Editorial - “All a-Board!”
The title of last month’s editorial, “A Night (and Week) to Remember!”, is an allusion to a famous book and movie about the sinking of the Titanic; the editorial that followed recounts the experiences of distinguished EP Charlotte Yeh, MD, after she had been struck by a car and became a patient in a busy Washington DC Level I trauma center. In Dr Yeh’s June 2014 article for Health Affairs she characterized her care as uneven and neglectful of her overall well-being. The care also appeared to be fragmented, sloppy, callous, and uncoordinated.
We did not comment last month on one aspect of her experience: after her radiologic studies were completed, Dr Yeh was brought back to the ED on a stretcher and parked in an ED hallway where she remained through the night, admitted but “boarding” in the ED waiting for an inpatient bed to become available. When the day crew that arrived 15 hours later recognized Dr Yeh as an EP, she was moved from the hallway to a private room. For Dr Yeh, being in an ED hallway was not the most significant problem associated with her ED care, but for most ED patients, being a hallway patient for many hours frequently overshadows all of the efforts of the many dedicated, hardworking EPs and nurses to provide our patients with the best care possible. Too often nowadays, the ED hallway has become the intersection of clinical care, comfort, length of stay, and patient satisfaction.
Ironically, Dr Yeh wrote that she “took comfort in being left in the hallway,” because to her “it meant that [she] was okay, that the hospital staff wasn’t so worried” about her and, conversely, after being moved to a darkened room with the door shut so that she could sleep, she felt abandoned.
Most patients in the overcrowded, urban, academic medical center EDs throughout the country prefer rooms—not hallways—until they are either discharged or admitted to an inpatient bed. Factoring in the constant noise and light, the uncomfortable ED stretchers, and the sometimes many hours spent in a hallway, is it any wonder that, nationwide, inpatient satisfaction scores of patients admitted through the ED are about 2 to 2.5 points lower than are those of patients admitted directly to an inpatient service? For many EPs and ED nurses, the hardest and most frequent decision they must make is whether to move a previously evaluated patient out of a room to a hallway, or to evaluate and treat a new patient outside of the room. Many factors contribute to this deplorable situation: ED overcrowding from other hospital closings, an increasing number of patients coming or sent to EDs because of the lack of primary care providers, and the growing number of patients waiting in EDs for inpatient isolation rooms. In fairness, the care of a patient on a hallway bed is not necessarily compromised. A 2012 Archives of Internal Medicine article questioned the assumption that favorable patient satisfaction scores correlate with quality of care; and bringing newly arrived patients into the ED as soon as possible, rather than making them wait in the waiting room for a room or cubicle to become available, certainly advances their care. But all that being said, why should so many patients have to spend time on hallway stretchers? If activities in EDs are closely integrated with activities in the rest of the hospital, the ED boarding situation can only improve significantly.

Letters to the Editor: Adverse Effects of Tramadol Overuse
Adverse Effects of Tramadol Overuse
To the Editor I very much enjoyed the review article “Appropriate Analgesic Use in the Emergency Department” (Emerg Med. 2014;46[6]:248-255). The discussion of tramadol neglected to mention the fact that overuse of Tramadol can precipitate hyponatremia and epileptic seizures. For this reason, Tramadol should be avoided in patients with seizure disorder. Similarly, other drugs like cyclobenzaprine and tricyclic antidepressants can provoke seizures. Tramadol should not be prescribed to patients on antidepressants or cyclobenzaprine.

You are correct that tramadol use, most commonly in overdose situations or withdrawal following chronic use, has been associated with seizures. Unfortunately, the same is true for many of the narcotic medications we discussed. Seizures in the setting of opioid administration usually occur when given in high doses via the parenteral route. Care must be taken when administering any opioid medication to a patient with an underlying seizure disorder. Given the space limitations of our article, we were unable to discuss all of the adverse effects associated with analgesic use.

Additional Therapy for Taxus Ingestion
To the Editor I read with interest your article “Death and Taxus” (Emerg Med. 2014;46[6]:256-259) as the taxus plant is so ubiquitous in community plantings. (We had a number of them in front of my childhood home, and I find it amazing that we never ate the berries.)
Regarding the treatment for yew berry intoxication, I did not see mention of lipid emulsion therapy for cardiac membrane stabilization. Any comments on this therapy? I have had good responses with lipid emulsion use in overdose scenarios with cardiovascular collapse where other agents, for example, bicarbonate infusion, have failed. Given the relative safety of the infusion as compared to the morbidity of the intoxication, it seems that intralipid therapy merits a mention.

In Reply We appreciate the thoughtful letter of Dr Silver. Indeed we believe there may be a role for intravenous lipid emulsion therapy in patients with Taxus (taxine) intoxication. The data supporting its benefit come from dozens of case reports and animal models, and the most convincing data derive from the treatment of bupivacaine toxicity. Lipid emulsion therapy is widely assumed to sequester lipophilic toxins within the circulating lipid emulsion and thereby assist in its removal from the affected organ. The Log P (a measure of lipid solubility) for taxine is similar to that for bupivacaine (both about 3)1 supporting its potential to be solubilized by the exogenously-administered lipid. There are no data from either experimental or clinical model to directly support its use, but as you suggest, the therapy is generally safe when administered appropriately.2 We therefore support its use in patients not otherwise responding to conventional therapy. Since lipid emulsion may also sequester medications administered therapeutically, such as amiodarone, appropriate caution should be observed.3

Better care is the best defense: High-value clinical practice vs defensive medicine
"I view every patient as a potential lawsuit." This statement is jolting. Yet more than 69% of neurosurgeons in a recent study said they agreed or strongly agreed with this survey question.1 What are its implications for patients, for clinical practice, and for the US health care system?
There are many frustrations in the delivery of health care today, for patients as well as for physicians. For physicians, concern about medical liability is a large one, with secondary implications for both health care costs and quality. The Institute of Medicine has estimated that $765 billion—or 30 cents out of every dollar spent on health care—is wasted annually in the United States, adding to the financial burden of health care without benefiting patients.2 A significant portion of this waste, estimated at $210 billion, is related to unnecessary services that are under the control of physicians, including overuse and misuse of diagnostic testing and treatment. This type of care is not only wasteful, but also has the potential to harm.
Factors thought to be responsible for this inappropriate care include the expectations of patients, physician or patient discomfort with uncertainty, and unnecessary and costly consultations. But the factor that physicians cite most often is concern about malpractice suits, raised by 76% of physicians responding to a survey.3
THE DILEMMAS ILLUSTRATED
Here are two cases—to which we will return later—that illustrate the dilemmas faced by physicians deciding how aggressively to pursue a diagnosis:
Patient 1. A 32-year-old woman comes to your office for evaluation of intermittent headaches over the past year. After a detailed history and a normal physical examination, you believe that these are tension headaches. Should you order an imaging study of the brain, just to avoid the risk of a malpractice suit in the unlikely event that this could be the presenting symptom of a brain tumor?
Patient 2. A 60-year-old man presents to the emergency room with pleuritic chest pain. Calculation of pretest probability by modified Wells criteria indicates that pulmonary embolus is unlikely. Because missing the diagnosis can lead to a malpractice suit, should you still order computed tomographic (CT) pulmonary angiography to rule out an embolus?
JUST ONE MORE TEST CAN’T HURT…
Defensive medicine is the ordering or avoiding of tests or procedures primarily out of concern about malpractice liability.4 It increases health care costs, but by how much is unclear.5 It can harm the patient-physician relationship and trust and can also harm patients, especially if overtesting and treatment lead to false-positive results and more tests, which actually can result in liability. And it is not the highest-value care for patients.
Physicians have an ethical duty to do what is best for the individual patient; they also have a responsibility to society to practice effective health care that uses resources responsibly.6 And despite telling ourselves and our patients that one more test will give us confirmation of results and therefore comfort, a recent review found that tests performed based on symptoms with low risk of being caused by serious illness “do little to reassure patients, decrease their anxiety, or resolve their symptoms.”7
MALPRACTICE LIABILITY RISK: PERCEPTION AND REALITY
Physicians often overestimate their risk of liability. Only a small percentage (5%) of claims go to trial, and of those, 90% are won by the physician, according to a 2008 analysis by the Physician Insurers Association of America.8 A study of claims between 2002 and 2005 found that 4.5% of claims resulted in trial verdicts, of which 80% were in favor of the physician, with cases against internists and internal medicine-based subspecialists least likely to result in a trial verdict (2.7%).9
Even so, being sued is extremely stressful and is associated with distinct physical and emotional distress for most physicians.10,11 Charles has found that, “As a group, physicians are acutely sensitive to any suggestions that they have failed to meet the standard of care or are not ‘good’ doctors… This accusation of failure represents a personal assault.”11
Physician concerns about liability are not very different in states with tort reforms such as damage caps compared with those without.5 Some posit that physicians may overestimate the risk of liability as part of the human tendency to overestimate the risk of rare events that are difficult to experience and difficult to control.12
In the study of neurosurgeons cited previously, 72% of respondents said they ordered imaging, 67% did laboratory tests, and 66% referred patients for consults “solely” to “minimize the risk of a lawsuit.”1 The authors of the study maintain that, over time, this affects the standard of care. “While physicians in the past may have used a thorough history and physical to guide imaging, in this study, 72% of neurosurgeons surveyed stated that they order additional imaging studies solely to mitigate liability risk. This suggests that in reality, imaging is becoming a standard part of the initial workup.”1 Unfortunately, this new standard of care is based on false assumptions and is artificially and inappropriately changed. That perception of liability risk deeply influences practice.
DO THE RIGHT THING: AVOIDING UNNECESSARY TESTING
But physicians also acknowledge the need to follow practice guidelines and to avoid unnecessary testing. In one survey,13 79% strongly or moderately agreed with the statement that physicians “should adhere to clinical guidelines that discourage the use of interventions that have a small proven advantage over standard intervention but cost much more”; 89% strongly or moderately agreed that “doctors need to take a more prominent role in limiting use of unnecessary tests”; and 78% said they “should be solely devoted to individual patients’ best interests, even if that is expensive.”13
This may be summarized as, “Provide the clinically appropriate care to the patient based on the best evidence.” But of course, this is easier said than done.
THE ROLE OF EVIDENCE-BASED GUIDELINES
Evidence-based practice guidelines can help support the provision of clinically (and ethically) appropriate care. Medical custom—the care expected of reasonable clinicians under similar circumstances—is generally the legal standard in determining whether a clinician has met a duty of care to a patient in a lawsuit.14 But practice guidelines can provide strong evidence of what constitutes reasonable care and can, over time, help set the standard for quality of care.
Clinical practice guidelines have grown in recent years, especially after the Institute of Medicine embraced them as a means to address variation in practice patterns and quality of care. But guidelines can conflict. Their effective implementation relies on clinical judgment. If a guideline is not appropriate in a particular case, documentation of why the guideline was not followed may prove prudent. Guidelines are not a safe harbor and have and will be used both defensively and offensively. They are not the last word, but rather another type of expert evidence.15 However, they are an important one. At the end of the day, the best care is the best defense.
Guidelines not only educate physicians, they also should be used by physicians to educate patients. In addition to developing guidelines for physicians, professional societies should develop and disseminate public education materials that inform patients and their families and caregivers about clinically appropriate care and the problems resulting from overuse and misuse of care.
GETTING BACK TO BASICS
Kroenke noted that preliminary data suggest that the history typically accounts for 75% or more of the diagnostic yield when evaluating common symptoms, the physical examination 10% to 15%, and testing generally less than 10%.16 Yet health care reimbursement in the United States contains incentives in precisely the reverse order. So, not surprisingly, we keep on testing away. Kroenke says that countering the rush to test will be as challenging and slow as trying to reverse a generation of antibiotic overprescribing.16
Over time, our reliance on technology as a diagnostic tool has increased, with less emphasis on the history and particularly on the physical examination to solve diagnostic puzzles. Yet most diagnostic errors in a study of outpatient primary care visits were related to breakdowns in the clinical interaction, including the taking of the medical history, the performance of the physical examination, and the ordering of tests. Technologies such as the electronic health record, which can assist in the care of patients, are also a potential source of error and shortcuts in care, as when copying and pasting is used inappropriately.17 Recognizing the increasing use of technology in practice and team-based approaches to improving care, Singh et al have called for caution and for more “focus on basic clinical skills and related cognitive processes.”18
The erosion of physical examination skills, discomfort with diagnostic uncertainty, and fear of malpractice litigation have combined to create a perfect storm of technologic overuse and misuse. Unfortunately, this means that our modus operandi is all too frequently built around testing rather than touching.19
At the same time, it is well established that patients often sue because of dissatisfaction, especially with physician communication and interpersonal skills.14 Emphasizing the basic skills that include taking a carefully crafted history, performing a skillful physical examination, and communicating effectively and compassionately with patients at every encounter is probably the most successful strategy for simultaneously avoiding malpractice litigation, reducing overused and misused diagnostic testing, and conserving precious health care resources.
Another part of the strategy should include routinely considering a number of straightforward questions before ordering diagnostic tests, such as “Will the test result change my care of the patient?” and “How does ordering this test compare in value with other management strategies for the patient?”20,21
RETURNING TO THE CASES
Regarding patient 1, the 32-year-old woman with intermittent headaches, the American College of Radiology identified imaging for headache in its list of five areas submitted to the Choosing Wisely campaign in which care may be overused or misused. Specifically, the American College of Radiology says, “Don’t do imaging for uncomplicated headache” in the absence of specific risk factors for structural disease, noting that “incidental findings lead to additional medical procedures and expense that do not improve patient well-being.”22
For patient 2, the 60-year-old man with pleuritic chest pain, both the American College of Physicians and the American College of Radiology strongly recommend against CT pulmonary angiography for patients in whom calculation of pretest probability indicates a low pretest probability of pulmonary embolism.22,23 Patients such as these should undergo D-dimer testing rather than CT pulmonary angiography. In this setting, a negative D-dimer test effectively rules out pulmonary embolism and avoids both the radiation and cost associated with the unnecessary imaging study.
According to the Ethics Manual of the American College of Physicians,6 “physicians have an obligation to promote their patients’ welfare in an increasingly complex health care system. This entails forthrightly helping patients to understand clinical recommendations and make informed choices among all appropriate care options… It also includes stewardship of finite health care resources so that as many health care needs as possible can be met, whether in the physician’s office, in the hospital or long-term care facility, or at home.”6 The basic principles of beneficence and nonmaleficence are aligned with doing the right thing for our patients—ie, providing the appropriate care at the right time and avoiding too much care or too little care. Guided by scientific evidence as well as by guidelines and official recommendations based on such evidence, we are in the best position to provide optimal care for our patients while simultaneously minimizing the risk of malpractice litigation.
As is the case with overprescribing, we must look critically at the inappropriate use of tests and other care applied under the rationale of not wanting to “miss anything”—and the unspoken drivers of financial incentives, new or advanced tests and procedures, and defensive medicine. We know what needs to be done. And nothing short of evidence-based high-value care will do.

"I view every patient as a potential lawsuit." This statement is jolting. Yet more than 69% of neurosurgeons in a recent study said they agreed or strongly agreed with this survey question.1 What are its implications for patients, for clinical practice, and for the US health care system?
There are many frustrations in the delivery of health care today, for patients as well as for physicians. For physicians, concern about medical liability is a large one, with secondary implications for both health care costs and quality. The Institute of Medicine has estimated that $765 billion—or 30 cents out of every dollar spent on health care—is wasted annually in the United States, adding to the financial burden of health care without benefiting patients.2 A significant portion of this waste, estimated at $210 billion, is related to unnecessary services that are under the control of physicians, including overuse and misuse of diagnostic testing and treatment. This type of care is not only wasteful, but also has the potential to harm.
Factors thought to be responsible for this inappropriate care include the expectations of patients, physician or patient discomfort with uncertainty, and unnecessary and costly consultations. But the factor that physicians cite most often is concern about malpractice suits, raised by 76% of physicians responding to a survey.3
THE DILEMMAS ILLUSTRATED
Here are two cases—to which we will return later—that illustrate the dilemmas faced by physicians deciding how aggressively to pursue a diagnosis:
Patient 1. A 32-year-old woman comes to your office for evaluation of intermittent headaches over the past year. After a detailed history and a normal physical examination, you believe that these are tension headaches. Should you order an imaging study of the brain, just to avoid the risk of a malpractice suit in the unlikely event that this could be the presenting symptom of a brain tumor?
Patient 2. A 60-year-old man presents to the emergency room with pleuritic chest pain. Calculation of pretest probability by modified Wells criteria indicates that pulmonary embolus is unlikely. Because missing the diagnosis can lead to a malpractice suit, should you still order computed tomographic (CT) pulmonary angiography to rule out an embolus?
JUST ONE MORE TEST CAN’T HURT…
Defensive medicine is the ordering or avoiding of tests or procedures primarily out of concern about malpractice liability.4 It increases health care costs, but by how much is unclear.5 It can harm the patient-physician relationship and trust and can also harm patients, especially if overtesting and treatment lead to false-positive results and more tests, which actually can result in liability. And it is not the highest-value care for patients.
Physicians have an ethical duty to do what is best for the individual patient; they also have a responsibility to society to practice effective health care that uses resources responsibly.6 And despite telling ourselves and our patients that one more test will give us confirmation of results and therefore comfort, a recent review found that tests performed based on symptoms with low risk of being caused by serious illness “do little to reassure patients, decrease their anxiety, or resolve their symptoms.”7
MALPRACTICE LIABILITY RISK: PERCEPTION AND REALITY
Physicians often overestimate their risk of liability. Only a small percentage (5%) of claims go to trial, and of those, 90% are won by the physician, according to a 2008 analysis by the Physician Insurers Association of America.8 A study of claims between 2002 and 2005 found that 4.5% of claims resulted in trial verdicts, of which 80% were in favor of the physician, with cases against internists and internal medicine-based subspecialists least likely to result in a trial verdict (2.7%).9
Even so, being sued is extremely stressful and is associated with distinct physical and emotional distress for most physicians.10,11 Charles has found that, “As a group, physicians are acutely sensitive to any suggestions that they have failed to meet the standard of care or are not ‘good’ doctors… This accusation of failure represents a personal assault.”11
Physician concerns about liability are not very different in states with tort reforms such as damage caps compared with those without.5 Some posit that physicians may overestimate the risk of liability as part of the human tendency to overestimate the risk of rare events that are difficult to experience and difficult to control.12
In the study of neurosurgeons cited previously, 72% of respondents said they ordered imaging, 67% did laboratory tests, and 66% referred patients for consults “solely” to “minimize the risk of a lawsuit.”1 The authors of the study maintain that, over time, this affects the standard of care. “While physicians in the past may have used a thorough history and physical to guide imaging, in this study, 72% of neurosurgeons surveyed stated that they order additional imaging studies solely to mitigate liability risk. This suggests that in reality, imaging is becoming a standard part of the initial workup.”1 Unfortunately, this new standard of care is based on false assumptions and is artificially and inappropriately changed. That perception of liability risk deeply influences practice.
DO THE RIGHT THING: AVOIDING UNNECESSARY TESTING
But physicians also acknowledge the need to follow practice guidelines and to avoid unnecessary testing. In one survey,13 79% strongly or moderately agreed with the statement that physicians “should adhere to clinical guidelines that discourage the use of interventions that have a small proven advantage over standard intervention but cost much more”; 89% strongly or moderately agreed that “doctors need to take a more prominent role in limiting use of unnecessary tests”; and 78% said they “should be solely devoted to individual patients’ best interests, even if that is expensive.”13
This may be summarized as, “Provide the clinically appropriate care to the patient based on the best evidence.” But of course, this is easier said than done.
THE ROLE OF EVIDENCE-BASED GUIDELINES
Evidence-based practice guidelines can help support the provision of clinically (and ethically) appropriate care. Medical custom—the care expected of reasonable clinicians under similar circumstances—is generally the legal standard in determining whether a clinician has met a duty of care to a patient in a lawsuit.14 But practice guidelines can provide strong evidence of what constitutes reasonable care and can, over time, help set the standard for quality of care.
Clinical practice guidelines have grown in recent years, especially after the Institute of Medicine embraced them as a means to address variation in practice patterns and quality of care. But guidelines can conflict. Their effective implementation relies on clinical judgment. If a guideline is not appropriate in a particular case, documentation of why the guideline was not followed may prove prudent. Guidelines are not a safe harbor and have and will be used both defensively and offensively. They are not the last word, but rather another type of expert evidence.15 However, they are an important one. At the end of the day, the best care is the best defense.
Guidelines not only educate physicians, they also should be used by physicians to educate patients. In addition to developing guidelines for physicians, professional societies should develop and disseminate public education materials that inform patients and their families and caregivers about clinically appropriate care and the problems resulting from overuse and misuse of care.
GETTING BACK TO BASICS
Kroenke noted that preliminary data suggest that the history typically accounts for 75% or more of the diagnostic yield when evaluating common symptoms, the physical examination 10% to 15%, and testing generally less than 10%.16 Yet health care reimbursement in the United States contains incentives in precisely the reverse order. So, not surprisingly, we keep on testing away. Kroenke says that countering the rush to test will be as challenging and slow as trying to reverse a generation of antibiotic overprescribing.16
Over time, our reliance on technology as a diagnostic tool has increased, with less emphasis on the history and particularly on the physical examination to solve diagnostic puzzles. Yet most diagnostic errors in a study of outpatient primary care visits were related to breakdowns in the clinical interaction, including the taking of the medical history, the performance of the physical examination, and the ordering of tests. Technologies such as the electronic health record, which can assist in the care of patients, are also a potential source of error and shortcuts in care, as when copying and pasting is used inappropriately.17 Recognizing the increasing use of technology in practice and team-based approaches to improving care, Singh et al have called for caution and for more “focus on basic clinical skills and related cognitive processes.”18
The erosion of physical examination skills, discomfort with diagnostic uncertainty, and fear of malpractice litigation have combined to create a perfect storm of technologic overuse and misuse. Unfortunately, this means that our modus operandi is all too frequently built around testing rather than touching.19
At the same time, it is well established that patients often sue because of dissatisfaction, especially with physician communication and interpersonal skills.14 Emphasizing the basic skills that include taking a carefully crafted history, performing a skillful physical examination, and communicating effectively and compassionately with patients at every encounter is probably the most successful strategy for simultaneously avoiding malpractice litigation, reducing overused and misused diagnostic testing, and conserving precious health care resources.
Another part of the strategy should include routinely considering a number of straightforward questions before ordering diagnostic tests, such as “Will the test result change my care of the patient?” and “How does ordering this test compare in value with other management strategies for the patient?”20,21
RETURNING TO THE CASES
Regarding patient 1, the 32-year-old woman with intermittent headaches, the American College of Radiology identified imaging for headache in its list of five areas submitted to the Choosing Wisely campaign in which care may be overused or misused. Specifically, the American College of Radiology says, “Don’t do imaging for uncomplicated headache” in the absence of specific risk factors for structural disease, noting that “incidental findings lead to additional medical procedures and expense that do not improve patient well-being.”22
For patient 2, the 60-year-old man with pleuritic chest pain, both the American College of Physicians and the American College of Radiology strongly recommend against CT pulmonary angiography for patients in whom calculation of pretest probability indicates a low pretest probability of pulmonary embolism.22,23 Patients such as these should undergo D-dimer testing rather than CT pulmonary angiography. In this setting, a negative D-dimer test effectively rules out pulmonary embolism and avoids both the radiation and cost associated with the unnecessary imaging study.
According to the Ethics Manual of the American College of Physicians,6 “physicians have an obligation to promote their patients’ welfare in an increasingly complex health care system. This entails forthrightly helping patients to understand clinical recommendations and make informed choices among all appropriate care options… It also includes stewardship of finite health care resources so that as many health care needs as possible can be met, whether in the physician’s office, in the hospital or long-term care facility, or at home.”6 The basic principles of beneficence and nonmaleficence are aligned with doing the right thing for our patients—ie, providing the appropriate care at the right time and avoiding too much care or too little care. Guided by scientific evidence as well as by guidelines and official recommendations based on such evidence, we are in the best position to provide optimal care for our patients while simultaneously minimizing the risk of malpractice litigation.
As is the case with overprescribing, we must look critically at the inappropriate use of tests and other care applied under the rationale of not wanting to “miss anything”—and the unspoken drivers of financial incentives, new or advanced tests and procedures, and defensive medicine. We know what needs to be done. And nothing short of evidence-based high-value care will do.

Home sleep tests have lower initial cost, but less value, too
A sleep physician, when presented with probable obstructive sleep apnea, needs to study the patient to confirm diagnosis, then treat the patient. The hard part is the treatment. The physician needs to convince people to accept continuous positive airway pressure (CPAP) therapy.
Dr. Charles W. Atwood, FCCP, associate professor of medicine at the University of Pittsburgh, recently reported that in a controlled Veterans Affairs environment, over 2 years the cost of a home sleep test was $564 less than that of an in-lab study (CHEST Physician, July 2014 p. 27). It is no surprise that the test cost less; however, he also stated that there was no difference in clinical outcomes after 2 years of follow up.
I have practiced sleep medicine in a group of five physicians, all of whom are board certified in pulmonary disease and sleep medicine. Our studies are usually performed in an American Academy of Sleep Medicine–accredited eight-bed lab or a neighboring, accredited two-bed lab.
Whenever possible, we perform split-night studies on OSA patients. We utilize home sleep tests (HSTs) when appropriate, in accord with AASM guidelines. Our HST patients are taught how to wear the testing device and if the study is positive, patients are given a 3-day trial of autotitrating CPAP, after a mask fitting, individual instructions, and the opportunity to call for help, 24/7.
On the other hand, we sometimes see HST devices that have been mailed to patients; and if the study is positive, a CPAP machine is mailed. We see patients who have had an HST ordered by a non-sleep physician, and the treatment is left to the durable medical equipment company. The physician seems to assume that the DME supplier will appropriately fit patient with mask and follow patient’s compliance.
Unfortunately, this does not always happen. Patients may never be followed. Patients have appeared in our office, after 5 years of using CPAP, because they heard that there is a way to check compliance, or that they can get a new machine. Some patients’ masks are held together with masking tape and superglue; and some patients have significant ulcerations on the bridge of their nose because of improper mask fit.
In our five-physician practice of sleep medicine, we use the equivalent of a full-time staff person to interact with the DME companies on the patient’s behalf, and to correct problems with CPAP machines and masks.
Clearly, an HST without follow-up does not yield equivalent compliance compared with a lab split-night study. In the lab, the patient is introduced to CPAP by a compassionate sleep technologist, who is present during the titration to allay anxiety, to change masks as needed, and to reassure apprehensive patients. Without follow-up care, there is a much higher noncompliance rate.
Not only does the patient suffer when noncompliant with CPAP because of lack of adequate follow-up after an HST, but the bed partner’s sleep is disturbed, families are disturbed by the patient’s symptoms, job performance may suffer, and a sleepy driver is a potential danger to self and community. Payers may save dollars by paying for the HST per se; but without adequate follow-up of a patient after an HST, future health issues or accidents obviate any savings to the payer.
Conclusion: In a controlled setting, such as a Veterans Affairs hospital, where a sleep physician has control of testing, CPAP delivery, and follow-up, an HST may offer compliance similar to that of an in-lab study. However, in a community practice, even in a suburb where patients are well informed regarding their health issues, unless an HST is performed in a sleep center or by a physician knowledgeable in sleep medicine, who follows the patient and checks compliance, there is a major difference in the clinical success rate.
Without clinical follow-up of patient compliance, an HST per se may initially cost less, but the HST provides less value.

Cruising With Disaster
I recently returned from a pleasure cruise to celebrate a milestone birthday. (I’m not telling you which one—but it did make me eligible for government health care!) Prior to embarking on this adventure, I had dreams of calm blue-green waters, endless plates of delectable food, sitting on the stateroom veranda drinking wine while watching the sunset, and exciting land and sea excursions.
However, I must admit that I also felt apprehensive. Just a year ago, one of my best friends lost his wife to severe influenza and necrotizing pneumonia while on a cruise. This disastrous event occurred very rapidly (what I call “from cough to death in less than 48 hours”) and in the same locale as my cruise. So, you can imagine my concern.
To prepare myself, I did a bit of research on the types of infectious diseases occurring aboard ship. The leading cause of human acute viral gastroenteritis on cruise ships is norovirus, outbreaks of which have increased significantly in recent years1 and always garner significant media attention.
However, the most frequent consultation with a ship’s medical team on most cruises is for respiratory illness.2 Outbreaks are not uncommon, particularly within flu season (October through May in the Northern hemisphere and April through September in the Southern hemisphere). Unfortunately, flu season is year round in the tropics and subtropics.3 There have also been occurrences of invasive meningococcal disease (four cases in the Mediterranean in October 2012, one of which was ultimately fatal)4 and cyclosporiasis (on two successive voyages embarking from Australia in 2010).5
Considering the detrimental consequences for passengers and the subsequent high costs for cruise companies, disease outbreaks on cruise ships represent a serious public health issue.6 Unfortunately, contagious disease on commercial ships tends to be poorly managed, as there is little capacity to confirm a case or isolate to curb transmission.7 (Personally, I was pleased—and relieved—to see that crew members stood outside every restaurant on the ship offering passengers hand disinfectant gel.)
I’m not trying to be alarmist. After all, I had a great cruise free of concerns. But I think anyone who sets sail should be aware of the circumstances should illness or injury occur. Here is some of what I learned through research and experience:
The cruise ship medical facility is not equivalent to your local hospital. Each ship in the fleet of a major cruise line contains a sick bay (to use a nautical term) with staff available 24 hours a day, but they are typically equipped to treat only minor, nonemergent conditions. I was told by the ship’s physician that he mostly sees upper respiratory infections, seasickness, and back pain. All ships have a physician on board who is trained in emergency medicine,8 and usually there are at least two RNs as well.
The medical facilities tend to resemble an infirmary or walk-in clinic rather than a “floating hospital.” There may be some simple equipment—a ventilator or a small x-ray machine—and the medical staff may be able to perform simple lab tests (eg, to check for infection or monitor glucose). But there is no capacity for advanced imaging, no ICU, and no store of blood in the event a transfusion is needed. Limited medications are available on board, but the inventories vary and are usually related to common conditions.
You should also know that there is no international body to regulate medical care on a passenger ship.9 The closest guidance comes from the American College of Emergency Physicians (ACEP), whose “Guidelines of Care for Cruise Ship Medical Facilities” was first published in 1996 (most recent revision, 2013).10,11 They stipulate that shipboard infirmaries must have equipment to handle a range of diagnoses and treatments: wheelchairs, a stretcher and backboard for spine immobilization, lab capabilities, oxygen, ECG, two defibrillators, cardiac monitors, and vital sign monitoring. Cruise RNs are required to have a minimum of two years of recent hospital experience, particularly in cardiac care, trauma, and internal medicine.
ACEP’s guidelines have become an international reference for the practice of cruise medicine.12 The proviso to their use is that they are based on member consensus rather than documented facts.
If there is an emergency on board, you are most likely on your own! You will be referred to a facility on land and disembarked to receive care—and the ship’s medical staff makes that call, not you. The “local” hospital may be at some distance from the port, necessitating transportation (which can be expensive), and in remote areas, the standards may not be what you are accustomed to in the United States. (There is the added difficulty that once you have recovered, you will have to make your own arrangements to get home.)
In the event of a serious emergency—a heart attack or stroke—the Coast Guard may step in to airlift you from the ship. But they aren’t obligated to risk a dangerous helicopter flight in bad weather, or if the ship is more than 250 miles from shore. Cruise ships do not commonly deviate course for evacuation purposes unless doing so will likely result in a markedly improved outcome.
On the next page: Will health insurance cover you?
See also: Dr. Bukata's comment on this editorial
What about health insurance? Will it cover you? Most plans do not cover medical services on board, which means you will pay out-of-pocket for any costs incurred. The bill can range from a few hundred to several thousand dollars. If you receive treatment or medicine from the ship’s medical team, the cost will be charged to your personal account. You could then file a claim with your personal insurance carrier to recoup whatever is covered by your health policy.
Travel insurance, which usually costs between 5% and 8% of the total cost of the trip, could cover the rest. In addition to medical costs, you can buy insurance policies that cover a wide range of trip interruption and cancellation situations, as well as medical evacuation.
Travel health insurance is your best protection. Consumer Reports recommends avoiding commission-driven policies sold by tour operators, cruise-line representatives, and travel agents. Instead, check out an online broker (such as insuremytrip.com) that sells coverage from multiple companies and allows you to tailor a plan to your needs.8
Many employers purchase travel insurance for their employees, which covers both business and pleasure trips. This type of policy is particularly convenient if an expensive emergency procedure, such as evacuation from the ship and/or a hospital stay in a foreign port, is necessary.
Not all perils at sea are contagious. Norovirus and motion sickness aren’t the only health concerns onboard. Falls and cardiac problems are also quite common. The CDC estimates that injuries, typically from slips, trips, or falls, account for 12% to 18% of shipboard medical visits. Obviously, anyone can fall, but those with limited mobility or who require assistance (eg, cane, walker, or wheelchair) are particularly at risk from wet decks and rough waters. (Factor in a cocktail or two, and even the normally ambulatory will have trouble navigating!)
If you have a bad outcome, don’t expect to win a lawsuit against the cruise line. Be sure to actually read the lengthy form you sign before boarding the ship. Courts have ruled that a cruise line may not be held vicariously liable for the negligence of a ship’s physician. There is no medical malpractice for care rendered on board. Traditionally, the physician and nurses are private contractors.
Ultimately, I think pleasure cruises are worth the time and effort for the prepared cruiser. I intend to go again. And this editorial is not an indictment of the physicians and nurses who work hard and do a wonderful job on cruises to maintain the health of passengers and crew. I just don’t want anyone caught unaware if they set sail for an adventure and find more than they wanted.
I would love to hear about any experience, positive or negative, that you have had with cruise medicine. Contact me at [email protected].

Prior to embarking on this adventure, I had dreams of calm blue-green waters, endless plates of delectable food, sitting on the stateroom veranda drinking wine while watching the sunset, and exciting land and sea excursions.
However, I must admit that I also felt apprehensive. Just a year ago, one of my best friends lost his wife to severe influenza and necrotizing pneumonia while on a cruise. This disastrous event occurred very rapidly (what I call “from cough to death in less than 48 hours”) and in the same locale as my cruise. So, you can imagine my concern.
To prepare myself, I did a bit of research on the types of infectious diseases occurring aboard ship. The leading cause of human acute viral gastroenteritis on cruise ships is norovirus, outbreaks of which have increased significantly in recent years1 and always garner significant media attention.
However, the most frequent consultation with a ship’s medical team on most cruises is for respiratory illness.2 Outbreaks are not uncommon, particularly within flu season (October through May in the Northern hemisphere and April through September in the Southern hemisphere). Unfortunately, flu season is year round in the tropics and subtropics.3 There have also been occurrences of invasive meningococcal disease (four cases in the Mediterranean in October 2012, one of which was ultimately fatal)4 and cyclosporiasis (on two successive voyages embarking from Australia in 2010).5
Considering the detrimental consequences for passengers and the subsequent high costs for cruise companies, disease outbreaks on cruise ships represent a serious public health issue.6 Unfortunately, contagious disease on commercial ships tends to be poorly managed, as there is little capacity to confirm a case or isolate to curb transmission.7 (Personally, I was pleased—and relieved—to see that crew members stood outside every restaurant on the ship offering passengers hand disinfectant gel.)
I’m not trying to be alarmist. After all, I had a great cruise free of concerns. But I think anyone who sets sail should be aware of the circumstances should illness or injury occur. Here is some of what I learned through research and experience:
The cruise ship medical facility is not equivalent to your local hospital. Each ship in the fleet of a major cruise line contains a sick bay (to use a nautical term) with staff available 24 hours a day, but they are typically equipped to treat only minor, nonemergent conditions. I was told by the ship’s physician that he mostly sees upper respiratory infections, seasickness, and back pain. All ships have a physician on board who is trained in emergency medicine,8 and usually there are at least two RNs as well.
The medical facilities tend to resemble an infirmary or walk-in clinic rather than a “floating hospital.” There may be some simple equipment—a ventilator or a small x-ray machine—and the medical staff may be able to perform simple lab tests (eg, to check for infection or monitor glucose). But there is no capacity for advanced imaging, no ICU, and no store of blood in the event a transfusion is needed. Limited medications are available on board, but the inventories vary and are usually related to common conditions.
You should also know that there is no international body to regulate medical care on a passenger ship.9 The closest guidance comes from the American College of Emergency Physicians (ACEP), whose “Guidelines of Care for Cruise Ship Medical Facilities” was first published in 1996 (most recent revision, 2013).10,11 They stipulate that shipboard infirmaries must have equipment to handle a range of diagnoses and treatments: wheelchairs, a stretcher and backboard for spine immobilization, lab capabilities, oxygen, ECG, two defibrillators, cardiac monitors, and vital sign monitoring. Cruise RNs are required to have a minimum of two years of recent hospital experience, particularly in cardiac care, trauma, and internal medicine.
ACEP’s guidelines have become an international reference for the practice of cruise medicine.12 The proviso to their use is that they are based on member consensus rather than documented facts.
If there is an emergency on board, you are most likely on your own! You will be referred to a facility on land and disembarked to receive care—and the ship’s medical staff makes that call, not you. The “local” hospital may be at some distance from the port, necessitating transportation (which can be expensive), and in remote areas, the standards may not be what you are accustomed to in the United States. (There is the added difficulty that once you have recovered, you will have to make your own arrangements to get home.)
In the event of a serious emergency—a heart attack or stroke—the Coast Guard may step in to airlift you from the ship. But they aren’t obligated to risk a dangerous helicopter flight in bad weather, or if the ship is more than 250 miles from shore. Cruise ships do not commonly deviate course for evacuation purposes unless doing so will likely result in a markedly improved outcome.
On the next page: Will health insurance cover you?

What about health insurance? Will it cover you? Most plans do not cover medical services on board, which means you will pay out-of-pocket for any costs incurred. The bill can range from a few hundred to several thousand dollars. If you receive treatment or medicine from the ship’s medical team, the cost will be charged to your personal account. You could then file a claim with your personal insurance carrier to recoup whatever is covered by your health policy.
Travel insurance, which usually costs between 5% and 8% of the total cost of the trip, could cover the rest. In addition to medical costs, you can buy insurance policies that cover a wide range of trip interruption and cancellation situations, as well as medical evacuation.
Travel health insurance is your best protection. Consumer Reports recommends avoiding commission-driven policies sold by tour operators, cruise-line representatives, and travel agents. Instead, check out an online broker (such as insuremytrip.com) that sells coverage from multiple companies and allows you to tailor a plan to your needs.8
Many employers purchase travel insurance for their employees, which covers both business and pleasure trips. This type of policy is particularly convenient if an expensive emergency procedure, such as evacuation from the ship and/or a hospital stay in a foreign port, is necessary.
Not all perils at sea are contagious. Norovirus and motion sickness aren’t the only health concerns onboard. Falls and cardiac problems are also quite common. The CDC estimates that injuries, typically from slips, trips, or falls, account for 12% to 18% of shipboard medical visits. Obviously, anyone can fall, but those with limited mobility or who require assistance (eg, cane, walker, or wheelchair) are particularly at risk from wet decks and rough waters. (Factor in a cocktail or two, and even the normally ambulatory will have trouble navigating!)
If you have a bad outcome, don’t expect to win a lawsuit against the cruise line. Be sure to actually read the lengthy form you sign before boarding the ship. Courts have ruled that a cruise line may not be held vicariously liable for the negligence of a ship’s physician. There is no medical malpractice for care rendered on board. Traditionally, the physician and nurses are private contractors.
Ultimately, I think pleasure cruises are worth the time and effort for the prepared cruiser. I intend to go again. And this editorial is not an indictment of the physicians and nurses who work hard and do a wonderful job on cruises to maintain the health of passengers and crew. I just don’t want anyone caught unaware if they set sail for an adventure and find more than they wanted.
I would love to hear about any experience, positive or negative, that you have had with cruise medicine. Contact me at [email protected].

The Medical Roundtable: Celiac Disease and Gluten Free: What's Real and What's Myth?
DR. LEFFLER: My name is Dr. Daniel Leffler. I’m in the Division of Gastroenterology at Beth Israel Deaconess Medical Center, and I direct the clinical research at our Celiac Center.
MS. DENNIS: My name is Melinda Dennis and I’m the nutrition coordinator of the Celiac Center at Beth Israel Deaconess Medical Center. I work with Dr. Leffler, Dr. Kelly, and the other Celiac Center gastroenterologists.
DR. MUSHLIN: Great. So, as the moderator of this conversation, I’d like to start us off with a case. This case presented to me in my primary care practice.
I saw a Harvard Medical student who came to see me regarding a stress fracture in her right foot. She was a runner and had run in 3marathons over the last 4 years. She was quite slender and had a BMI of only 19, but she quite adamantly denied being anorectic or bulimic.
She had been treated for anemia in her senior year of college with iron. She had no idea whether her anemia had improved. She had always had irregular menses since menarche, but for the past year as her running increased, she was completely amenorrheic.
After physical examination, x-ray examination revealed that she did indeed have a fracture of a metatarsal. I then obtained a bone density examination that showed osteoporosis—not just osteopenia but osteoporosis. She also had an anemia with a hematocrit of 33%, and she had microcytic hypochromic indices. I then, because of her osteoporosis, got a vitamin D level, which was definitely low. It was under 20, and that’s the lower limit of normal in our institution. She also had slightly elevated parathyroid hormone levels.
I obtained an IgA tissue transglutaminase (tTG) antibody test, and it was highly positive. I then placed her on a gluten-free diet with calcium, vitamin D, and oral iron supplementation, and that’s the case.
Dr. Leffler, would you say that this would be a pretty typical presentation of celiac disease?
DR. LEFFLER: Yes. I think all of us working with celiac disease have seen patients just like this, but it also highlights the fact that there really is no typical patient with celiac disease. A picture of what was previously considered typical involved severe malabsorptive symptoms, but that was really just scratching the tip of the iceberg for what is out there. While iron-deficiency anemia, osteoporosis, and vitamin D deficiency are very common in celiac disease, you can have all or none of these symptoms. Like this patient, you can have no gastrointestinal symptoms. Alternatively, you can have predominantly gastrointestinal symptoms.
Certainly, this patient had a number of red flags that would make you worry about celiac disease such as the early onset fracture, the osteoporosis, and the iron-deficiency anemia. Although the latter is not an uncommon thing to see in a young woman, it’s the combination of all these factors that, in my mind, would alert a clinician to the fact that these are not normal findings for a young healthy woman.
DR. MUSHLIN: If you looked at all the patients who were ultimately diagnosed with celiac disease who presented to the family practitioner or the primary care internist, what would you say would be the most common red flags? I know this case, which is a true case, had a lot of red flags, but what would be the most common symptoms that might raise your consciousness that you might be dealing with celiac disease?
DR. LEFFLER: Approximately 40% of patients with celiac disease will have chronic gastrointestinal symptoms. These can vary and can be very similar to those of irritable bowel syndrome, but gastrointestinal symptoms in the presence of a significant nutritional deficiency like iron deficiency or vitamin D deficiency, as in this case, would be very typical of celiac disease and raise a lot of red flags. A lot of these patients will also have either a personal history or a family history of other autoimmune diseases, type 1 diabetes, thyroid disease, and other similar conditions.
So, very common presentations and red flag conditions would include a patient who says, “my mother has thyroid disease” or “I have thyroid disease and now I’m iron deficient,” or “now I’m experiencing significant fatigue.” Overall, the most common presentations of celiac disease these days are gastrointestinal symptoms, iron-deficiency anemia, vitamin D deficiency, and fatigue.
DR. MUSHLIN: Certainly, all of those things are seen in an internist’s or a family practitioner’s office. I guess the real key here is that when you start to see this constellation, you should raise your consciousness that there may be one unifying diagnosis rather than multiple diagnoses.
DR. LEFFLER: Exactly. I think that the response to therapy can also be a good hint that there might be something else going on. Most young women with iron-deficiency anemia simply due to menses will do pretty well on oral iron supplementation alone. If they have severe and significant anemia and it’s just not responding to iron supplementation for instance, or if their vitamin D level is low and it does not improve with a regular dose of vitamin D, then you really have to wonder whether there is something that’s preventing absorption of this nutrient in the intestinal tract. Once you get to that level, then celiac disease is by far the most common diagnosis in these situations.
DR. MUSHLIN: We are having this colloquium here in Boston and there are a lot of people in the greater Boston area who are of Northern European extraction. Are there certain ethnic groups that have a predominance of celiac disease, or can it be found in virtually any ethnic group?
DR. LEFFLER: Earlier, we used to say this was essentially an Irish/Italian or western European disease, but now we can more easily pick out the populations that celiac disease doesn’t occur in. Celiac disease has a strong genetic predisposition with human leukocyte antigen (HLA) types, but really the populations that are at risk for celiac disease cover most of the globe: all of North and South America, Europe, the Middle East, North Africa, India, and northern China. Southeast Asians and Sub-Saharan Africans have a very low risk, but the majority of people have a significant risk of celiac disease, and I think that like all other autoimmune and inflammatory disorders, whether it’s type 1 diabetes or asthma or inflammatory bowel disease, the prevalence of celiac disease just continues to rise over time. We’re seeing it in populations that never had this disorder before.
DR. MUSHLIN: Why do you think the prevalence is increasing? Is it that our diagnostic ability is better, or do you think it’s truly increasing?
DR. LEFFLER: Well, we’ve certainly gotten a lot better at diagnosing celiac disease. You mentioned the celiac tTG antibody test earlier, which has really revolutionized the way that we diagnose celiac disease because it’s so accurate, affordable, and widespread. That being said, even in prevalence studies,1,2 there really is a dramatic increase—something in the range of a doubling—and true prevalence every 30 years or so. This is right alongside these other autoimmune and inflammatory diseases.
Clearly, nothing in our genetic heritability is changing that quickly. It’s something in the environment that is leading to an increase in the incidence of celiac disease and autoimmune diseases in general. Lots of people have theories about what that might be, and the most common theory is that we live in such a clean environment now that our immune system doesn’t have the normal feedback it needs to develop in a healthy way, and so, our immune function may start to become abnormal.
DR. MUSHLIN: This is similar to the asthma hypothesis.
DR. LEFFLER: Exactly. All of this can in some way be explained by the hygiene hypothesis.
DR. MUSHLIN: Right. When you live in Germany and the cows are housed in the same house that you live in, there’s less asthma.
DR. LEFFLER: Exactly. The same phenomenon has been seen in celiac disease in some populations, especially in northern Europe where you cross a national border and you encounter very different socioeconomic conditions. Even though you have virtually the same genetic lineage, you can have very different rates of celiac disease. I think this is very much the case.
DR. MUSHLIN: Ms. Dennis, I have a large number of patients who come into my office and say to me, “I went on a gluten-free diet and I feel so much better.” Can you address the question of gluten sensitivity versus true celiac disease? Do you feel comfortable doing that?
MS. DENNIS: Sure. We know that celiac disease is a genetic autoimmune disease, and we know that non-celiac gluten sensitivity is not considered an autoimmune disease. Dr. Leffler would be in a better position to address the issue of whether there is an inflammatory response, but there are plenty of people who come into the office confused about the 2. In order to obtain a diagnosis of non-celiac gluten sensitivity, celiac disease and wheat allergy would both need to be ruled out.
There is no positive gene testing for non-celiac gluten sensitivity, but what makes it difficult for patients is that the symptoms can mimic one another almost exactly. All the gastrointestinal symptoms, as well as some of the other extraintestinal manifestations like headaches, poor concentration, memory loss, and other similar conditions, can occur in both conditions. It’s complicated, and there is much more research that needs to be done in this area.
DR. LEFFLER: I’ll just corroborate all of that. We’ve known about celiac disease for a long time. Gluten intolerance, or non-celiac gluten sensitivity as it’s becoming more commonly known, is a very new entity that we’ve really only starting believing in, clinically at least, over the last couple of years. We’re learning about it quickly, but we still don’t have a very good sense of its prevalence.
It does appear to be a non-inflammatory disorder, which separates it from celiac disease. It doesn’t appear to have any autoimmune component and likely does not have a lot of the long-term risks associated with celiac disease such as osteoporosis or even cancer and infection risk, but at the same time, it can be associated with significant quality of life impairment, and the symptoms can mimic celiac disease. So, it is something that everyone needs to be aware of; however, while the diet-related treatment is similar, it seems that a lot of the peripheral things that we should do for our celiac patients such as getting them vaccinated and performing a bone mineral density study are not required for patients who have non-celiac gluten intolerance or gluten sensitivity. We do recommend that people work with their physicians to make a clear distinction between these 2 disorders.
DR. MUSHLIN: Just to expand on that point, would a negative tTG antibody test basically exclude celiac disease with a high degree of certainty and leave you with a diagnosis of gluten sensitivity without celiac disease (assuming the symptoms were consistent)?
DR. LEFFLER: Yes. For a typical patient who is on a regular gluten-containing diet and doesn’t have a strong family history of celiac disease or other factors that would increase risk, a negative tTG would certainly be sufficient and would imply that the chances that the patient has true celiac disease are quite low. We can then proceed with a non-celiac gluten sensitivity diagnosis and see how the patient does clinically.
DR. MUSHLIN: It seems that everywhere I go, there are more and more gluten-free choices. In fact, the wife of my closest friend here in town just started a gluten-free bakery and she’s so busy that he’s making deliveries for her now every day instead of 3 times a week. Are there any dangers to adhering to a gluten-free diet?
MS. DENNIS: There are inherent nutritional deficiencies in a gluten-free diet. So, if the diet is not proper, yes, you can lack certain vitamins and minerals. For example, wheat is a major source of protein and B vitamins as well as iron, trace minerals, and fiber.
When you switch to the gluten-free diet, you need to be able to replace those nutrients. Many people don’t focus immediately on the alternative whole and healthier gluten-free grains like amaranth, buckwheat, millet, quinoa, sorghum, and teff. They tend to move toward rice, corn, and potatoes, which tend to be lower in fiber, nutrient poor, and can cause or exacerbate constipation and weight gain when eaten in large quantities. So, that’s one of the main issues.
Additionally, we find that many people are concurrently lactose intolerant when they’re first diagnosed with celiac disease. So, we need to consider the possibility that their calcium and vitamin D intakes may be inadequate. Then, of course, we need to consider the B vitamins, which are present throughout the food chain but are present in large quantities in grains.
DR. MUSHLIN: Ms. Dennis, a lot of my patients are curious about purchasing gluten-free materials either from stores or online. Do you feel comfortable recommending any websites that you feel are legitimate for our patients to access?
Regarding consumer access, it is important to find safe gluten-free foods that are not cross-contaminated. We now have a Food Allergen Labeling and Consumer Protection Act in place that states that if wheat protein is in an FDA-regulated food, it must be labeled as such on the package. That applies to FDA foods but not USDA foods. Dieticians know the difference between these two and can educate their patients, but it’s not obvious by just reading a label.
The most obvious sources of gluten are wheat, rye, barley, malt, oats (unless they are specifically labeled and processed such that they are gluten free), and brewer’s yeast. These are easily identifiable, but it takes a little bit of education to get familiar with hidden gluten sources. One of the primary things that a person can do is make sure that their grains and flour-based products are labeled “gluten free” to help avoid some of the risks of cross-contamination that come when gluten-free grains are contaminated with wheat, rye, or barley during the farming, processing, or milling practices that typically occur in this country.
DR. MUSHLIN: So let’s say I’ve got a patient who says to me, “Doc, I’ve got celiac disease. Can I ever eat out again? Can I ever go to a restaurant?” How would you advise them?
MS. DENNIS: I have celiac disease myself, and yes you can absolutely eat out. I was diagnosed 22 years ago. So much has changed in these last 2 decades that makes life a lot easier for us, but you do have to pay attention when dining out, not only to the ingredients that are going into the food but also to the preparation technique used.
If a newly diagnosed person goes out to eat, they would want to first choose a celiac-friendly restaurant, meaning a restaurant that has a gluten-free menu. Even then, I would suggest asking questions related to the ingredients and the preparation methods. For example, it’s pretty common knowledge among people with celiac disease that fryers are contaminated, but what’s less commonly known is that scrambled eggs can often be mixed with pancake batter to make them fluffy and increase their volume. Roasts and beef cuts that are served in a restaurant are often held in a broth that contains wheat, prior to being served. Baked potatoes may be put into a fryer just before serving them at the table.
It’s important that in the kitchen, where the food is being prepared, different utensils and skillets are used, and that the person preparing the food is paying attention to what cutting boards he/she is using and not cross-contaminating with other gluten-containing products. All of this being said, there is much more opportunity for people to dine out these days. However, you have to be very, very careful, and there are resources that can lead you to restaurants that are more inclined to understand food allergies and make allowances and substitutions for those on the gluten-free diet.
DR. MUSHLIN: Ms. Dennis, would you elaborate on how to access those resources, and can you also discuss a few reputable websites that can be used by people with gluten sensitivity?
MS. DENNIS: There are a number of national organizations that are deeply committed to celiac disease, the gluten-free diet, and those with non-celiac gluten sensitivity. In no particular order, these include the Celiac Disease Foundation (www.celiac.org), the Gluten Intolerance Group (www.gluten.net), the Celiac Sprue Association of the United States (CSA/USA, Inc; www.csaceliacs.info), the American Celiac Disease Alliance (americanceliac.org), and the National Foundation for Celiac Awareness (www.celiaccentral.org). These can all be easily found by a Google search. Each of them contains multiple listings of resources including restaurants, information about dining out, tips on how to eat when traveling, nutrition information, hidden gluten sources, blogs, and how to budget on the gluten-free diet. Many of them list celiac centers across the United States and describe how to find specific clinicians who are experts in this field. All of these are reputable sites.
I should mention that we have also launched a multi-level website especially designed for the nutritional management of celiac disease: CeliacNow.org. It’s useful for anyone on the gluten-free diet as well as practitioners who want to gain more information.
Back to your original question about dining out in particular, there are 2 resources that I recommend to patients. One of them is TriumphDining.com. Not only do they list grocery stores and food sources across the state, they also list restaurants. CeceliasMarketplace.com is also another excellent website. Both of these sites also offer books on the topic. Finally, the forum at www.celiac.com is a place that most people find almost immediately when they’re diagnosed.
DR. MUSHLIN: Good. Is there any special designation for people who do nutritional work such as yourself who specialize in celiac counseling, or can any registered nutritionist counsel someone appropriately?
MS. DENNIS: They are actually working on a certification program for the counseling of patients with celiac disease. I joined a taskforce about 5 years ago that developed nutritional guidelines for the Academy of Nutrition and Dietetics.3 These guidelines are available if dieticians want to train themselves on how to counsel a patient on the gluten-free diet, beginning with the initial visit through the follow-up visits. The guidelines include laboratory tests, case studies, and multiple patient handouts, and they constitute the industry’s major educational piece on celiac disease. Beyond that, you can examine books, articles, etc, written by a number of experts in the field. There’s currently no certification.
DR. LEFFLER: A lot of patients will come to me saying, “I saw a dietician and I knew more about the diet than they did. They were no help at all.” That is really a terribly frustrating thing for patients. So, clinicians want to make sure that they send their patients to somebody who has a fair degree of knowledge, interest, and expertise in celiac disease. Unfortunately, this expertise is just not that common these days.
DR. MUSHLIN: Ms. Dennis, how many hours do you normally have to spend to get a newly diagnosed patient with true celiac disease, not just gluten sensitivity, up to speed assuming they have normal intelligence, at least a high school education, and some kind of familiarity with the basics of nutrition. How many hours might it take for you to meet with them? Often when physicians send a patient for a consultation, it’s helpful to tell the patient that they may need to be seen a few times to get it right because sometimes patients are surprised or dismayed that 20minutes with someone hasn’t fixed them.
MS. DENNIS: In this hospital setting, I’m not able to see patients as often or for as long of a period of time as I would like, and that’s common across many, many nutrition practices. We have an hour to educate patients initially. In an ideal world, the patients would be back within a few weeks for part 2 for at least an hour, and then they would check in periodically for the next 3months, 6months, and then yearly for a wellness check.
You can absolutely not do this in one session, and so, I’ve designed nutrition counseling sessions to give patients a tremendous amount of information that they can read. I also instruct them to explore reputable sites, read the material that we’ve created, and then come back with questions. I always link them to a local support group, which is absolutely critical for the management of this lifestyle adjustment. They can’t cope with the condition alone, and they certainly can’t do it on a few hours of nutrition consulting.
DR. MUSHLIN: Are you folks doing group counseling yet at your institution? For example, patients who’ve spent an hour or greater with you can come back in a group setting to get their questions answered, have an open discussion, and obtain support from other fellow patients or from other individuals following the same diet.
MS. DENNIS: Our clinic visits are one-on-one, but we do offer patient education nights 3 times a year where 10 to 40 people join us, and one of the doctors and I sit and answer questions for an hour and a half. That is a great experience for the patients. It’s always a very warm environment, and we again connect them to our larger support group that serves all of New England, the Healthy Villi, and they’re able to attend conferences, expos, or large meetings at least 3 times a year.
DR. MUSHLIN: I certainly think that if the paradigms of helping patients with chronic ongoing illness can be managed, their illnesses are going to gravitate more and more toward exactly those kinds of group support models.
MS. DENNIS: I agree.
DR. MUSHLIN: Dr. Leffler, you’ve mentioned briefly that in follow-up with your patients who have celiac disease, you need to be careful or be aware of the possibility of low bone density, and you also mentioned that they need vaccinations. What vaccinations do they require and why?
DR. LEFFLER: One of the things that is not widely known about celiac disease is that it’s actually associated with functional hyposplenism. So, people with celiac disease have an increased risk of infections—primarily those involving encapsulated organisms but also other infections—and these infections can be more severe. Our general recommendations are to vaccinate all celiac patients for flu and pneumococcus regardless of their age. Unfortunately, we have seen cases of very severe pneumococcal sepsis in otherwise totally healthy immunocompetent patients with celiac disease. So, it is something that we recommend routinely to all of our patients.
DR. MUSHLIN: Regarding the unusual association of celiac disease with other medical situations, one of my colleagues here saw a patient with pulmonary hemosiderosis who happened to have celiac disease. Are there other unusual conditions that are associated with celiac disease?
DR. LEFFLER: Yes. That pulmonary condition is called Lane-Hamilton syndrome. It is quite rare, but we’ve seen a few cases of it.
One of the fascinating things about celiac disease is that it can affect any organ system in the body. You can see effects in the central nervous system, skin, bones, kidneys, reproductive system, lungs, and heart, and there are a number of reasons why celiac disease can be so far-reaching.
Part of it is just that chronic nutritional deficiencies can lead to widespread problems, but more fundamentally, people with celiac disease produce antibodies to tTG. That’s the blood test that is most commonly ordered—the IgA anti-tTG blood test. The enzyme tTG is found in all parts of the body. Its main job is to crosslink collagen. It’s very active in wound repair and building connective tissue, and when antibodies attack this enzyme, inflammation can occur anywhere in the body. Presumably, depending on the exact type of antibodies produced and polymorphisms in tTGs, you can have a direct autoimmune effect that’s triggered in the intestine but attacks the brain or virtually any other organ.
Gluten ataxia is a cardinal well-known phenomenon where you have cerebellar inflammation and cerebellar atrophy due to the celiac reaction. You can have dermatitis herpetiformis, which is an inflammatory reaction of the skin that mostly affects extensor surfaces. So, you have this autoimmune reaction that can attack any part of the body but starts in the intestine. Once you get celiac disease under control, for example by going on a gluten-free diet, these antibody levels decrease and the autoimmune reactions cease just as they do in the intestine. This is really a very unique way of thinking about an autoimmune disease.
DR. MUSHLIN: Because we’re talking so much about antibodies, do you follow antibody titers in people you’ve placed on a gluten-free diet?
DR. LEFFLER: Yes, I do. I follow them not because they’re really wonderful at monitoring celiac disease, because they’re not. There is plenty of research including some that we’ve done ourselves4,5 that shows that they’re not great at telling, for instance, recent gluten exposure or the degree of intestinal healing. There are lots of people who have completely normal antibody levels, but their intestine’s ability to heal is significantly damaged and vice versa. Some people still have mild elevations in their antibody levels, but their intestine looks pretty good.
On the other hand, there’s really no other tool that we have, and if you have somebody with antibody levels that are persistently elevated and never drop, or drop slightly but are still 2 to 3 times the upper limit of normal, you can be fairly certain that gluten is sneaking in somewhere, and they may not know it. They may be doing their best to follow a gluten-free diet. It could be something as simple as a single generic medication or a supplement that has gluten in it that they’re taking on a daily basis. We’ve seen issues of that sort, but if their antibody level is still high, it’s very helpful as a red flag that something’s not going right.
The first thing I’ll do is send them back to see Ms. Dennis to review the diet and see where the problems are cropping up. That will fix many of the problems, but it can take an awful lot of detective work to sort through basically everything that they’re putting in their mouth and see where that bit of gluten might be.
DR. MUSHLIN: So let’s say the family practitioner diagnoses celiac disease based on the patient’s history and physical findings, and the tTG antibody test is highly positive. The practitioner then sends the patient to a nutritionist, and the patient goes on a gluten-free diet. How should that family practitioner then follow up with the patient? You mentioned immunizations—influenza yearly and Pneumovax. What else should be routinely done by that practitioner, for example, in a rural community where the patient might not have access to a specialist?
DR. LEFFLER: I want to just mention that even with a positive antibody level, endoscopy is still necessary at the beginning for diagnosis. The standard of care for celiac disease these days includes checking celiac serologies approximately every 3 to 6months until they normalize, which depends on how high they are at the beginning. Some people start off with a relative titer of 1000, and some start off with a relative titer of 50. Obviously, the latter will normalize much more quickly.
What you want to see is an improvement in those levels, so you follow them approximately every 6months until they normalize. Then you perform a celiac blood test approximately every year just to make sure that the levels are staying low and that something hasn’t changed such that the patient suddenly has an elevated level. At least 1 bone mineral density test should be performed approximately 1 year after diagnosis once their vitamin D and any other nutritional deficiencies have been repleted. We can mention the nutrients to check in a second, and if those are normal, then the patient can go back to the bone mineral density recommendations for the regular population.
If their bone mineral density is low, then you want to keep a closer eye on them depending on how low it is. You can see a lot of improvement in bone mineral density in the first year after diagnosis with celiac disease, which is why we don’t typically check bone density right off the bat unless the patient has had fractures or something that we’re really worried about. It’s only the residual osteopenia or osteoporosis that they have after a year that we would treat differently.
Even after the initial dietary counseling, we strongly recommend that patients check in with their dietician once a year. Again, a gluten-free diet is a really big change. It’s tough. Things change all the time, and by following up with a specialist, you can tell them about how the foods you eat have changed. New recommendations on a yearly basis are also recommended.
As for vitamins, the most common nutrient deficiencies in people with celiac disease are currently vitamin D, iron, and zinc. Zinc is not one that’s commonly on people’s radar, but it is actually responsible for a lot of the hair and skin manifestations that people with celiac disease complain about and potentially responsible for some of the immune dysregulation as well.
DR. LEFFLER: Correct. Sometimes we will encounter people with a normal B12level and macrocytosis, and we will wonder where that’s coming from. That’s a good thing to check. B12and folate are rarely low in people with celiac disease, so we don’t always check them.
We’ll also check liver function tests at least once in the beginning because autoimmune liver disease can be associated with celiac disease. Thyroid disease is also often associated with celiac disease, so it’s important to make sure patients have had a thyroid stimulating hormone (TSH) test at least once, and you should consider repeating that every few years. Those are the routine things that we keep an eye on in celiac disease. So, there’s a little bit of a to-do list for your patients with celiac disease.
DR. MUSHLIN: Do you ever do genetic HLA testing?
DR. LEFFLER: Yes, we do. The genetic testing for celiac disease is very interesting. Most of the genes we test for, for example those involved in hemochromatosis or cystic fibrosis, are relatively diagnostic, ie, if you have the gene, you worry that you have the disease. Celiac disease is just the opposite. The celiac genes are HLA-DQ2 and DQ8. They are actually prevalent in approximately 40% of the general population. So, they’re prerequisite genes, but they are not diagnostic genes.
If you have these genes, it means nothing because obviously the vast majority of people with these genes never get celiac disease. On the other hand, if you don’t have these genes, then you virtually cannot get celiac disease. So, these genes are helpful for 2 types of people specifically.
First, genetic testing is helpful for people who are already on a gluten-free diet and aren’t willing to do a gluten challenge. Obviously, your genes don’t change with diet, so if you get a negative genetic test, you can rule out celiac disease even while the patient is on a diet, and there’s no other way you can do that. Second, genetic testing is helpful for patients with a strong family history of celiac disease. The testing is very popular now among children whose parents have celiac disease. They have a pretty high chance of having the gene—at least 50%—but if they don’t, they’re off the hook for life, which is a nice thing to be able to tell someone. So, I think this test really does have its utility.
DR. MUSHLIN: Let’s go back to the initial diagnosis and the role of endoscopy.
DR. LEFFLER: The modern celiac blood tests, which are tTG, deamidated gliadin peptide (DGP), and endomysial antibody (EMA), are all highly accurate, have >90% sensitivity, and are specific. On the other hand, the average patient you’re going to test probably has a 5% to 10% pretest probability of celiac disease. Even the best of our tests only have a positive predictive value of approximately 80%, which means that if you rely on a serology alone, 1 out of 5 patients you diagnose with celiac disease is probably going to be a false positive. So, for that reason, because it’s a life-long diagnosis, you’re going to expose people to a lot of inconvenience to say the least as well as other medical testing, bone density analysis, and immunizations they may not need. The recommendation is still that all patients with a positive serology should follow up and get an endoscopy, which continues to be the gold standard for diagnosis.
DR. MUSHLIN: Would that be an endoscopy with a small bowel biopsy?
DR. LEFFLER: Right. A duodenal biopsy.
DR. MUSHLIN: So, depending on your population, there would be a 1in 5 chance of a false positive test. What would be the chance of a false negative test?
DR. LEFFLER: That would be well under 5% depending on the population.
DR. MUSHLIN: So, it’s 95% sensitive in picking it up, correct?
DR. LEFFLER: Right. In general, the one thing that can throw off some of these blood tests is IgA deficiency, which is a common problem that is also enriched in the celiac population. Approximately 2% of people with celiac disease have IgA deficiency, and because these blood tests are typically IgA-based, if you’re really worried about the diagnosis, you can check the total IgA level at the time of tTG measurement. If both of those are normal, and your patient is on a regular gluten-containing diet, you’re really fine in the vast majority of circumstances.
DR. MUSHLIN: In antibody testing, do you assay for endomysial antibodies in addition to transglutaminase, or do you assay for only one? Do you think that your ability to trust these tests is very dependent on the laboratory you’re using? How many of these antibody tests do you get?
DR. LEFFLER: Typically just one. There’s very little data to suggest that doing multiple tests at the same time does anything but drive up the cost. They’re all similar. They’re all typically very concordant.
So, you’re going to have one positive, and you’re going to have a second one positive. The only times I’ll consider it again are with somebody who has a borderline test and I’m considering whether or not they need an endoscopy. In that case, maybe a second one to help push me one way or the other would be helpful, but really, tTG is your workhorse. Although there are multiple assays available and almost all of them are good, I think that physicians across the country really can’t go wrong just sticking with IgA-tTG as their primary test.
DR. MUSHLIN: Terrific. Ms. Dennis, do you have anything else you want to articulate?
MS. DENNIS: Standard multivitamin mineral supplementation is a general recommendation for people with celiac disease. So, when they come into the clinic, I always recommend a gluten-free multivitamin and mineral supplement with or without iron depending on their age, gender, and laboratory values.
Sometimes our patients need vitamin B complex supplements. Sometimes it’s just a simple complaint of energy and may suggest that their B12level is lower than normal. We like to see it around 400mg/mL or above.
Calcium and vitamin D supplementation is also very common. In general, it’s difficult to get about 1200mg of calcium a day through diet alone, particularly if lactose intolerance is present. So, we often prescribe calcium supplements with vitamin D to get to that total goal.
Then, of course, Dr. Leffler was mentioning vitamin D. We recommend it based on laboratory values and diet, and almost all of our patients need vitamin D supplementation. I would also suggest that omega-3 fatty acids be considered in the dietary assessment of our patients.
DR. MUSHLIN: Why is that?
MS. DENNIS: In general, Americans aren’t getting the required amounts of omega-3 fatty acids, and eating fish is not always popular. Very few of our patients can tell me that they get approximately 6 ounces of a dark deep-water fatty fish per week, which is a general recommendation. So, if it’s necessary, I’ll suggest an omega-3supplement, but that’s always individually determined.
The last thing I wanted to mention was that just recently the North American Society for the Study of Celiac Disease was formed. It’s a clinician group, and their intention and mission is to spearhead celiac awareness in the medical and nutrition communities as well as in the public sector. They aim to be a guiding force because up until now, support has generally come from volunteer nonprofit organizations all across the country. So, we’re looking for a little bit more of a structured single entity that can help us bring awareness much more quickly to all populations.
DR. MUSHLIN: In the multivitamin supplement, would you also want to make sure that they got some zinc?
MS. DENNIS: Yes. All the multivitamins contain zinc, but often, we need to recommend extra zinc. There’s typically not 100% of your daily recommended zinc in a multi. It’s present in trace amounts. So, if needed, we’ll check serum zinc and give zinc for 6 to 8 weeks before retesting.
DR. MUSHLIN: Dr. Leffler, let’s go quickly to the question of malignancy associated with long-standing celiac disease. In my own clinical practice experience, I’ve actually had 2 patients with celiac disease who developed non-Hodgkin’s lymphoma. Do you think there’s a definite association between malignancies and celiac disease?
DR. LEFFLER: Unfortunately, it seems like that association is clear. The overall risk of malignancy in people with celiac disease is about twofold higher than what we see in the general population. The majority of that, as you saw with your patient, is due to non-Hodgkin’s lymphoma.
There’s also an increased risk of small intestinal adenocarcinomas and small intestinal lymphomas. They’re also known as enteropathy-associated T-cell lymphomas. So, there is a significant risk.
However, we don’t screen for malignancies in patients with celiac disease any differently than we do in the general population. This is because, thankfully, the risk of malignancy drops after diagnosis, and at approximately 5 years after diagnosis, the risk is pretty close to that of the general population. So, the risk seems to be related to chronic immune activation, and once you get that immune activation under control, the risk drops. It’s a little bit of a reward that helps patients to actually follow the diet and control their disease.
DR. MUSHLIN: Well, this has been a wonderful conversation. I’ve learned a tremendous amount, and I’m very grateful to you both.
FoxP2 Media LLC is the publisher of The Medical Roundtable.
DR. LEFFLER: My name is Dr. Daniel Leffler. I’m in the Division of Gastroenterology at Beth Israel Deaconess Medical Center, and I direct the clinical research at our Celiac Center.
MS. DENNIS: My name is Melinda Dennis and I’m the nutrition coordinator of the Celiac Center at Beth Israel Deaconess Medical Center. I work with Dr. Leffler, Dr. Kelly, and the other Celiac Center gastroenterologists.
DR. MUSHLIN: Great. So, as the moderator of this conversation, I’d like to start us off with a case. This case presented to me in my primary care practice.
I saw a Harvard Medical student who came to see me regarding a stress fracture in her right foot. She was a runner and had run in 3marathons over the last 4 years. She was quite slender and had a BMI of only 19, but she quite adamantly denied being anorectic or bulimic.
She had been treated for anemia in her senior year of college with iron. She had no idea whether her anemia had improved. She had always had irregular menses since menarche, but for the past year as her running increased, she was completely amenorrheic.
After physical examination, x-ray examination revealed that she did indeed have a fracture of a metatarsal. I then obtained a bone density examination that showed osteoporosis—not just osteopenia but osteoporosis. She also had an anemia with a hematocrit of 33%, and she had microcytic hypochromic indices. I then, because of her osteoporosis, got a vitamin D level, which was definitely low. It was under 20, and that’s the lower limit of normal in our institution. She also had slightly elevated parathyroid hormone levels.
I obtained an IgA tissue transglutaminase (tTG) antibody test, and it was highly positive. I then placed her on a gluten-free diet with calcium, vitamin D, and oral iron supplementation, and that’s the case.
Dr. Leffler, would you say that this would be a pretty typical presentation of celiac disease?
DR. LEFFLER: Yes. I think all of us working with celiac disease have seen patients just like this, but it also highlights the fact that there really is no typical patient with celiac disease. A picture of what was previously considered typical involved severe malabsorptive symptoms, but that was really just scratching the tip of the iceberg for what is out there. While iron-deficiency anemia, osteoporosis, and vitamin D deficiency are very common in celiac disease, you can have all or none of these symptoms. Like this patient, you can have no gastrointestinal symptoms. Alternatively, you can have predominantly gastrointestinal symptoms.
Certainly, this patient had a number of red flags that would make you worry about celiac disease such as the early onset fracture, the osteoporosis, and the iron-deficiency anemia. Although the latter is not an uncommon thing to see in a young woman, it’s the combination of all these factors that, in my mind, would alert a clinician to the fact that these are not normal findings for a young healthy woman.
DR. MUSHLIN: If you looked at all the patients who were ultimately diagnosed with celiac disease who presented to the family practitioner or the primary care internist, what would you say would be the most common red flags? I know this case, which is a true case, had a lot of red flags, but what would be the most common symptoms that might raise your consciousness that you might be dealing with celiac disease?
DR. LEFFLER: Approximately 40% of patients with celiac disease will have chronic gastrointestinal symptoms. These can vary and can be very similar to those of irritable bowel syndrome, but gastrointestinal symptoms in the presence of a significant nutritional deficiency like iron deficiency or vitamin D deficiency, as in this case, would be very typical of celiac disease and raise a lot of red flags. A lot of these patients will also have either a personal history or a family history of other autoimmune diseases, type 1 diabetes, thyroid disease, and other similar conditions.
So, very common presentations and red flag conditions would include a patient who says, “my mother has thyroid disease” or “I have thyroid disease and now I’m iron deficient,” or “now I’m experiencing significant fatigue.” Overall, the most common presentations of celiac disease these days are gastrointestinal symptoms, iron-deficiency anemia, vitamin D deficiency, and fatigue.
DR. MUSHLIN: Certainly, all of those things are seen in an internist’s or a family practitioner’s office. I guess the real key here is that when you start to see this constellation, you should raise your consciousness that there may be one unifying diagnosis rather than multiple diagnoses.
DR. LEFFLER: Exactly. I think that the response to therapy can also be a good hint that there might be something else going on. Most young women with iron-deficiency anemia simply due to menses will do pretty well on oral iron supplementation alone. If they have severe and significant anemia and it’s just not responding to iron supplementation for instance, or if their vitamin D level is low and it does not improve with a regular dose of vitamin D, then you really have to wonder whether there is something that’s preventing absorption of this nutrient in the intestinal tract. Once you get to that level, then celiac disease is by far the most common diagnosis in these situations.
DR. MUSHLIN: We are having this colloquium here in Boston and there are a lot of people in the greater Boston area who are of Northern European extraction. Are there certain ethnic groups that have a predominance of celiac disease, or can it be found in virtually any ethnic group?
DR. LEFFLER: Earlier, we used to say this was essentially an Irish/Italian or western European disease, but now we can more easily pick out the populations that celiac disease doesn’t occur in. Celiac disease has a strong genetic predisposition with human leukocyte antigen (HLA) types, but really the populations that are at risk for celiac disease cover most of the globe: all of North and South America, Europe, the Middle East, North Africa, India, and northern China. Southeast Asians and Sub-Saharan Africans have a very low risk, but the majority of people have a significant risk of celiac disease, and I think that like all other autoimmune and inflammatory disorders, whether it’s type 1 diabetes or asthma or inflammatory bowel disease, the prevalence of celiac disease just continues to rise over time. We’re seeing it in populations that never had this disorder before.
DR. MUSHLIN: Why do you think the prevalence is increasing? Is it that our diagnostic ability is better, or do you think it’s truly increasing?
DR. LEFFLER: Well, we’ve certainly gotten a lot better at diagnosing celiac disease. You mentioned the celiac tTG antibody test earlier, which has really revolutionized the way that we diagnose celiac disease because it’s so accurate, affordable, and widespread. That being said, even in prevalence studies,1,2 there really is a dramatic increase—something in the range of a doubling—and true prevalence every 30 years or so. This is right alongside these other autoimmune and inflammatory diseases.
Clearly, nothing in our genetic heritability is changing that quickly. It’s something in the environment that is leading to an increase in the incidence of celiac disease and autoimmune diseases in general. Lots of people have theories about what that might be, and the most common theory is that we live in such a clean environment now that our immune system doesn’t have the normal feedback it needs to develop in a healthy way, and so, our immune function may start to become abnormal.
DR. MUSHLIN: This is similar to the asthma hypothesis.
DR. LEFFLER: Exactly. All of this can in some way be explained by the hygiene hypothesis.
DR. MUSHLIN: Right. When you live in Germany and the cows are housed in the same house that you live in, there’s less asthma.
DR. LEFFLER: Exactly. The same phenomenon has been seen in celiac disease in some populations, especially in northern Europe where you cross a national border and you encounter very different socioeconomic conditions. Even though you have virtually the same genetic lineage, you can have very different rates of celiac disease. I think this is very much the case.
DR. MUSHLIN: Ms. Dennis, I have a large number of patients who come into my office and say to me, “I went on a gluten-free diet and I feel so much better.” Can you address the question of gluten sensitivity versus true celiac disease? Do you feel comfortable doing that?
MS. DENNIS: Sure. We know that celiac disease is a genetic autoimmune disease, and we know that non-celiac gluten sensitivity is not considered an autoimmune disease. Dr. Leffler would be in a better position to address the issue of whether there is an inflammatory response, but there are plenty of people who come into the office confused about the 2. In order to obtain a diagnosis of non-celiac gluten sensitivity, celiac disease and wheat allergy would both need to be ruled out.
There is no positive gene testing for non-celiac gluten sensitivity, but what makes it difficult for patients is that the symptoms can mimic one another almost exactly. All the gastrointestinal symptoms, as well as some of the other extraintestinal manifestations like headaches, poor concentration, memory loss, and other similar conditions, can occur in both conditions. It’s complicated, and there is much more research that needs to be done in this area.
DR. LEFFLER: I’ll just corroborate all of that. We’ve known about celiac disease for a long time. Gluten intolerance, or non-celiac gluten sensitivity as it’s becoming more commonly known, is a very new entity that we’ve really only starting believing in, clinically at least, over the last couple of years. We’re learning about it quickly, but we still don’t have a very good sense of its prevalence.
It does appear to be a non-inflammatory disorder, which separates it from celiac disease. It doesn’t appear to have any autoimmune component and likely does not have a lot of the long-term risks associated with celiac disease such as osteoporosis or even cancer and infection risk, but at the same time, it can be associated with significant quality of life impairment, and the symptoms can mimic celiac disease. So, it is something that everyone needs to be aware of; however, while the diet-related treatment is similar, it seems that a lot of the peripheral things that we should do for our celiac patients such as getting them vaccinated and performing a bone mineral density study are not required for patients who have non-celiac gluten intolerance or gluten sensitivity. We do recommend that people work with their physicians to make a clear distinction between these 2 disorders.
DR. MUSHLIN: Just to expand on that point, would a negative tTG antibody test basically exclude celiac disease with a high degree of certainty and leave you with a diagnosis of gluten sensitivity without celiac disease (assuming the symptoms were consistent)?
DR. LEFFLER: Yes. For a typical patient who is on a regular gluten-containing diet and doesn’t have a strong family history of celiac disease or other factors that would increase risk, a negative tTG would certainly be sufficient and would imply that the chances that the patient has true celiac disease are quite low. We can then proceed with a non-celiac gluten sensitivity diagnosis and see how the patient does clinically.
DR. MUSHLIN: It seems that everywhere I go, there are more and more gluten-free choices. In fact, the wife of my closest friend here in town just started a gluten-free bakery and she’s so busy that he’s making deliveries for her now every day instead of 3 times a week. Are there any dangers to adhering to a gluten-free diet?
MS. DENNIS: There are inherent nutritional deficiencies in a gluten-free diet. So, if the diet is not proper, yes, you can lack certain vitamins and minerals. For example, wheat is a major source of protein and B vitamins as well as iron, trace minerals, and fiber.
When you switch to the gluten-free diet, you need to be able to replace those nutrients. Many people don’t focus immediately on the alternative whole and healthier gluten-free grains like amaranth, buckwheat, millet, quinoa, sorghum, and teff. They tend to move toward rice, corn, and potatoes, which tend to be lower in fiber, nutrient poor, and can cause or exacerbate constipation and weight gain when eaten in large quantities. So, that’s one of the main issues.
Additionally, we find that many people are concurrently lactose intolerant when they’re first diagnosed with celiac disease. So, we need to consider the possibility that their calcium and vitamin D intakes may be inadequate. Then, of course, we need to consider the B vitamins, which are present throughout the food chain but are present in large quantities in grains.
DR. MUSHLIN: Ms. Dennis, a lot of my patients are curious about purchasing gluten-free materials either from stores or online. Do you feel comfortable recommending any websites that you feel are legitimate for our patients to access?
Regarding consumer access, it is important to find safe gluten-free foods that are not cross-contaminated. We now have a Food Allergen Labeling and Consumer Protection Act in place that states that if wheat protein is in an FDA-regulated food, it must be labeled as such on the package. That applies to FDA foods but not USDA foods. Dieticians know the difference between these two and can educate their patients, but it’s not obvious by just reading a label.
The most obvious sources of gluten are wheat, rye, barley, malt, oats (unless they are specifically labeled and processed such that they are gluten free), and brewer’s yeast. These are easily identifiable, but it takes a little bit of education to get familiar with hidden gluten sources. One of the primary things that a person can do is make sure that their grains and flour-based products are labeled “gluten free” to help avoid some of the risks of cross-contamination that come when gluten-free grains are contaminated with wheat, rye, or barley during the farming, processing, or milling practices that typically occur in this country.
DR. MUSHLIN: So let’s say I’ve got a patient who says to me, “Doc, I’ve got celiac disease. Can I ever eat out again? Can I ever go to a restaurant?” How would you advise them?
MS. DENNIS: I have celiac disease myself, and yes you can absolutely eat out. I was diagnosed 22 years ago. So much has changed in these last 2 decades that makes life a lot easier for us, but you do have to pay attention when dining out, not only to the ingredients that are going into the food but also to the preparation technique used.
If a newly diagnosed person goes out to eat, they would want to first choose a celiac-friendly restaurant, meaning a restaurant that has a gluten-free menu. Even then, I would suggest asking questions related to the ingredients and the preparation methods. For example, it’s pretty common knowledge among people with celiac disease that fryers are contaminated, but what’s less commonly known is that scrambled eggs can often be mixed with pancake batter to make them fluffy and increase their volume. Roasts and beef cuts that are served in a restaurant are often held in a broth that contains wheat, prior to being served. Baked potatoes may be put into a fryer just before serving them at the table.
It’s important that in the kitchen, where the food is being prepared, different utensils and skillets are used, and that the person preparing the food is paying attention to what cutting boards he/she is using and not cross-contaminating with other gluten-containing products. All of this being said, there is much more opportunity for people to dine out these days. However, you have to be very, very careful, and there are resources that can lead you to restaurants that are more inclined to understand food allergies and make allowances and substitutions for those on the gluten-free diet.
DR. MUSHLIN: Ms. Dennis, would you elaborate on how to access those resources, and can you also discuss a few reputable websites that can be used by people with gluten sensitivity?
MS. DENNIS: There are a number of national organizations that are deeply committed to celiac disease, the gluten-free diet, and those with non-celiac gluten sensitivity. In no particular order, these include the Celiac Disease Foundation (www.celiac.org), the Gluten Intolerance Group (www.gluten.net), the Celiac Sprue Association of the United States (CSA/USA, Inc; www.csaceliacs.info), the American Celiac Disease Alliance (americanceliac.org), and the National Foundation for Celiac Awareness (www.celiaccentral.org). These can all be easily found by a Google search. Each of them contains multiple listings of resources including restaurants, information about dining out, tips on how to eat when traveling, nutrition information, hidden gluten sources, blogs, and how to budget on the gluten-free diet. Many of them list celiac centers across the United States and describe how to find specific clinicians who are experts in this field. All of these are reputable sites.
I should mention that we have also launched a multi-level website especially designed for the nutritional management of celiac disease: CeliacNow.org. It’s useful for anyone on the gluten-free diet as well as practitioners who want to gain more information.
Back to your original question about dining out in particular, there are 2 resources that I recommend to patients. One of them is TriumphDining.com. Not only do they list grocery stores and food sources across the state, they also list restaurants. CeceliasMarketplace.com is also another excellent website. Both of these sites also offer books on the topic. Finally, the forum at www.celiac.com is a place that most people find almost immediately when they’re diagnosed.
DR. MUSHLIN: Good. Is there any special designation for people who do nutritional work such as yourself who specialize in celiac counseling, or can any registered nutritionist counsel someone appropriately?
MS. DENNIS: They are actually working on a certification program for the counseling of patients with celiac disease. I joined a taskforce about 5 years ago that developed nutritional guidelines for the Academy of Nutrition and Dietetics.3 These guidelines are available if dieticians want to train themselves on how to counsel a patient on the gluten-free diet, beginning with the initial visit through the follow-up visits. The guidelines include laboratory tests, case studies, and multiple patient handouts, and they constitute the industry’s major educational piece on celiac disease. Beyond that, you can examine books, articles, etc, written by a number of experts in the field. There’s currently no certification.
DR. LEFFLER: A lot of patients will come to me saying, “I saw a dietician and I knew more about the diet than they did. They were no help at all.” That is really a terribly frustrating thing for patients. So, clinicians want to make sure that they send their patients to somebody who has a fair degree of knowledge, interest, and expertise in celiac disease. Unfortunately, this expertise is just not that common these days.
DR. MUSHLIN: Ms. Dennis, how many hours do you normally have to spend to get a newly diagnosed patient with true celiac disease, not just gluten sensitivity, up to speed assuming they have normal intelligence, at least a high school education, and some kind of familiarity with the basics of nutrition. How many hours might it take for you to meet with them? Often when physicians send a patient for a consultation, it’s helpful to tell the patient that they may need to be seen a few times to get it right because sometimes patients are surprised or dismayed that 20minutes with someone hasn’t fixed them.
MS. DENNIS: In this hospital setting, I’m not able to see patients as often or for as long of a period of time as I would like, and that’s common across many, many nutrition practices. We have an hour to educate patients initially. In an ideal world, the patients would be back within a few weeks for part 2 for at least an hour, and then they would check in periodically for the next 3months, 6months, and then yearly for a wellness check.
You can absolutely not do this in one session, and so, I’ve designed nutrition counseling sessions to give patients a tremendous amount of information that they can read. I also instruct them to explore reputable sites, read the material that we’ve created, and then come back with questions. I always link them to a local support group, which is absolutely critical for the management of this lifestyle adjustment. They can’t cope with the condition alone, and they certainly can’t do it on a few hours of nutrition consulting.
DR. MUSHLIN: Are you folks doing group counseling yet at your institution? For example, patients who’ve spent an hour or greater with you can come back in a group setting to get their questions answered, have an open discussion, and obtain support from other fellow patients or from other individuals following the same diet.
MS. DENNIS: Our clinic visits are one-on-one, but we do offer patient education nights 3 times a year where 10 to 40 people join us, and one of the doctors and I sit and answer questions for an hour and a half. That is a great experience for the patients. It’s always a very warm environment, and we again connect them to our larger support group that serves all of New England, the Healthy Villi, and they’re able to attend conferences, expos, or large meetings at least 3 times a year.
DR. MUSHLIN: I certainly think that if the paradigms of helping patients with chronic ongoing illness can be managed, their illnesses are going to gravitate more and more toward exactly those kinds of group support models.
MS. DENNIS: I agree.
DR. MUSHLIN: Dr. Leffler, you’ve mentioned briefly that in follow-up with your patients who have celiac disease, you need to be careful or be aware of the possibility of low bone density, and you also mentioned that they need vaccinations. What vaccinations do they require and why?
DR. LEFFLER: One of the things that is not widely known about celiac disease is that it’s actually associated with functional hyposplenism. So, people with celiac disease have an increased risk of infections—primarily those involving encapsulated organisms but also other infections—and these infections can be more severe. Our general recommendations are to vaccinate all celiac patients for flu and pneumococcus regardless of their age. Unfortunately, we have seen cases of very severe pneumococcal sepsis in otherwise totally healthy immunocompetent patients with celiac disease. So, it is something that we recommend routinely to all of our patients.
DR. MUSHLIN: Regarding the unusual association of celiac disease with other medical situations, one of my colleagues here saw a patient with pulmonary hemosiderosis who happened to have celiac disease. Are there other unusual conditions that are associated with celiac disease?
DR. LEFFLER: Yes. That pulmonary condition is called Lane-Hamilton syndrome. It is quite rare, but we’ve seen a few cases of it.
One of the fascinating things about celiac disease is that it can affect any organ system in the body. You can see effects in the central nervous system, skin, bones, kidneys, reproductive system, lungs, and heart, and there are a number of reasons why celiac disease can be so far-reaching.
Part of it is just that chronic nutritional deficiencies can lead to widespread problems, but more fundamentally, people with celiac disease produce antibodies to tTG. That’s the blood test that is most commonly ordered—the IgA anti-tTG blood test. The enzyme tTG is found in all parts of the body. Its main job is to crosslink collagen. It’s very active in wound repair and building connective tissue, and when antibodies attack this enzyme, inflammation can occur anywhere in the body. Presumably, depending on the exact type of antibodies produced and polymorphisms in tTGs, you can have a direct autoimmune effect that’s triggered in the intestine but attacks the brain or virtually any other organ.
Gluten ataxia is a cardinal well-known phenomenon where you have cerebellar inflammation and cerebellar atrophy due to the celiac reaction. You can have dermatitis herpetiformis, which is an inflammatory reaction of the skin that mostly affects extensor surfaces. So, you have this autoimmune reaction that can attack any part of the body but starts in the intestine. Once you get celiac disease under control, for example by going on a gluten-free diet, these antibody levels decrease and the autoimmune reactions cease just as they do in the intestine. This is really a very unique way of thinking about an autoimmune disease.
DR. MUSHLIN: Because we’re talking so much about antibodies, do you follow antibody titers in people you’ve placed on a gluten-free diet?
DR. LEFFLER: Yes, I do. I follow them not because they’re really wonderful at monitoring celiac disease, because they’re not. There is plenty of research including some that we’ve done ourselves4,5 that shows that they’re not great at telling, for instance, recent gluten exposure or the degree of intestinal healing. There are lots of people who have completely normal antibody levels, but their intestine’s ability to heal is significantly damaged and vice versa. Some people still have mild elevations in their antibody levels, but their intestine looks pretty good.
On the other hand, there’s really no other tool that we have, and if you have somebody with antibody levels that are persistently elevated and never drop, or drop slightly but are still 2 to 3 times the upper limit of normal, you can be fairly certain that gluten is sneaking in somewhere, and they may not know it. They may be doing their best to follow a gluten-free diet. It could be something as simple as a single generic medication or a supplement that has gluten in it that they’re taking on a daily basis. We’ve seen issues of that sort, but if their antibody level is still high, it’s very helpful as a red flag that something’s not going right.
The first thing I’ll do is send them back to see Ms. Dennis to review the diet and see where the problems are cropping up. That will fix many of the problems, but it can take an awful lot of detective work to sort through basically everything that they’re putting in their mouth and see where that bit of gluten might be.
DR. MUSHLIN: So let’s say the family practitioner diagnoses celiac disease based on the patient’s history and physical findings, and the tTG antibody test is highly positive. The practitioner then sends the patient to a nutritionist, and the patient goes on a gluten-free diet. How should that family practitioner then follow up with the patient? You mentioned immunizations—influenza yearly and Pneumovax. What else should be routinely done by that practitioner, for example, in a rural community where the patient might not have access to a specialist?
DR. LEFFLER: I want to just mention that even with a positive antibody level, endoscopy is still necessary at the beginning for diagnosis. The standard of care for celiac disease these days includes checking celiac serologies approximately every 3 to 6months until they normalize, which depends on how high they are at the beginning. Some people start off with a relative titer of 1000, and some start off with a relative titer of 50. Obviously, the latter will normalize much more quickly.
What you want to see is an improvement in those levels, so you follow them approximately every 6months until they normalize. Then you perform a celiac blood test approximately every year just to make sure that the levels are staying low and that something hasn’t changed such that the patient suddenly has an elevated level. At least 1 bone mineral density test should be performed approximately 1 year after diagnosis once their vitamin D and any other nutritional deficiencies have been repleted. We can mention the nutrients to check in a second, and if those are normal, then the patient can go back to the bone mineral density recommendations for the regular population.
If their bone mineral density is low, then you want to keep a closer eye on them depending on how low it is. You can see a lot of improvement in bone mineral density in the first year after diagnosis with celiac disease, which is why we don’t typically check bone density right off the bat unless the patient has had fractures or something that we’re really worried about. It’s only the residual osteopenia or osteoporosis that they have after a year that we would treat differently.
Even after the initial dietary counseling, we strongly recommend that patients check in with their dietician once a year. Again, a gluten-free diet is a really big change. It’s tough. Things change all the time, and by following up with a specialist, you can tell them about how the foods you eat have changed. New recommendations on a yearly basis are also recommended.
As for vitamins, the most common nutrient deficiencies in people with celiac disease are currently vitamin D, iron, and zinc. Zinc is not one that’s commonly on people’s radar, but it is actually responsible for a lot of the hair and skin manifestations that people with celiac disease complain about and potentially responsible for some of the immune dysregulation as well.
DR. LEFFLER: Correct. Sometimes we will encounter people with a normal B12level and macrocytosis, and we will wonder where that’s coming from. That’s a good thing to check. B12and folate are rarely low in people with celiac disease, so we don’t always check them.
We’ll also check liver function tests at least once in the beginning because autoimmune liver disease can be associated with celiac disease. Thyroid disease is also often associated with celiac disease, so it’s important to make sure patients have had a thyroid stimulating hormone (TSH) test at least once, and you should consider repeating that every few years. Those are the routine things that we keep an eye on in celiac disease. So, there’s a little bit of a to-do list for your patients with celiac disease.
DR. MUSHLIN: Do you ever do genetic HLA testing?
DR. LEFFLER: Yes, we do. The genetic testing for celiac disease is very interesting. Most of the genes we test for, for example those involved in hemochromatosis or cystic fibrosis, are relatively diagnostic, ie, if you have the gene, you worry that you have the disease. Celiac disease is just the opposite. The celiac genes are HLA-DQ2 and DQ8. They are actually prevalent in approximately 40% of the general population. So, they’re prerequisite genes, but they are not diagnostic genes.
If you have these genes, it means nothing because obviously the vast majority of people with these genes never get celiac disease. On the other hand, if you don’t have these genes, then you virtually cannot get celiac disease. So, these genes are helpful for 2 types of people specifically.
First, genetic testing is helpful for people who are already on a gluten-free diet and aren’t willing to do a gluten challenge. Obviously, your genes don’t change with diet, so if you get a negative genetic test, you can rule out celiac disease even while the patient is on a diet, and there’s no other way you can do that. Second, genetic testing is helpful for patients with a strong family history of celiac disease. The testing is very popular now among children whose parents have celiac disease. They have a pretty high chance of having the gene—at least 50%—but if they don’t, they’re off the hook for life, which is a nice thing to be able to tell someone. So, I think this test really does have its utility.
DR. MUSHLIN: Let’s go back to the initial diagnosis and the role of endoscopy.
DR. LEFFLER: The modern celiac blood tests, which are tTG, deamidated gliadin peptide (DGP), and endomysial antibody (EMA), are all highly accurate, have >90% sensitivity, and are specific. On the other hand, the average patient you’re going to test probably has a 5% to 10% pretest probability of celiac disease. Even the best of our tests only have a positive predictive value of approximately 80%, which means that if you rely on a serology alone, 1 out of 5 patients you diagnose with celiac disease is probably going to be a false positive. So, for that reason, because it’s a life-long diagnosis, you’re going to expose people to a lot of inconvenience to say the least as well as other medical testing, bone density analysis, and immunizations they may not need. The recommendation is still that all patients with a positive serology should follow up and get an endoscopy, which continues to be the gold standard for diagnosis.
DR. MUSHLIN: Would that be an endoscopy with a small bowel biopsy?
DR. LEFFLER: Right. A duodenal biopsy.
DR. MUSHLIN: So, depending on your population, there would be a 1in 5 chance of a false positive test. What would be the chance of a false negative test?
DR. LEFFLER: That would be well under 5% depending on the population.
DR. MUSHLIN: So, it’s 95% sensitive in picking it up, correct?
DR. LEFFLER: Right. In general, the one thing that can throw off some of these blood tests is IgA deficiency, which is a common problem that is also enriched in the celiac population. Approximately 2% of people with celiac disease have IgA deficiency, and because these blood tests are typically IgA-based, if you’re really worried about the diagnosis, you can check the total IgA level at the time of tTG measurement. If both of those are normal, and your patient is on a regular gluten-containing diet, you’re really fine in the vast majority of circumstances.
DR. MUSHLIN: In antibody testing, do you assay for endomysial antibodies in addition to transglutaminase, or do you assay for only one? Do you think that your ability to trust these tests is very dependent on the laboratory you’re using? How many of these antibody tests do you get?
DR. LEFFLER: Typically just one. There’s very little data to suggest that doing multiple tests at the same time does anything but drive up the cost. They’re all similar. They’re all typically very concordant.
So, you’re going to have one positive, and you’re going to have a second one positive. The only times I’ll consider it again are with somebody who has a borderline test and I’m considering whether or not they need an endoscopy. In that case, maybe a second one to help push me one way or the other would be helpful, but really, tTG is your workhorse. Although there are multiple assays available and almost all of them are good, I think that physicians across the country really can’t go wrong just sticking with IgA-tTG as their primary test.
DR. MUSHLIN: Terrific. Ms. Dennis, do you have anything else you want to articulate?
MS. DENNIS: Standard multivitamin mineral supplementation is a general recommendation for people with celiac disease. So, when they come into the clinic, I always recommend a gluten-free multivitamin and mineral supplement with or without iron depending on their age, gender, and laboratory values.
Sometimes our patients need vitamin B complex supplements. Sometimes it’s just a simple complaint of energy and may suggest that their B12level is lower than normal. We like to see it around 400mg/mL or above.
Calcium and vitamin D supplementation is also very common. In general, it’s difficult to get about 1200mg of calcium a day through diet alone, particularly if lactose intolerance is present. So, we often prescribe calcium supplements with vitamin D to get to that total goal.
Then, of course, Dr. Leffler was mentioning vitamin D. We recommend it based on laboratory values and diet, and almost all of our patients need vitamin D supplementation. I would also suggest that omega-3 fatty acids be considered in the dietary assessment of our patients.
DR. MUSHLIN: Why is that?
MS. DENNIS: In general, Americans aren’t getting the required amounts of omega-3 fatty acids, and eating fish is not always popular. Very few of our patients can tell me that they get approximately 6 ounces of a dark deep-water fatty fish per week, which is a general recommendation. So, if it’s necessary, I’ll suggest an omega-3supplement, but that’s always individually determined.
The last thing I wanted to mention was that just recently the North American Society for the Study of Celiac Disease was formed. It’s a clinician group, and their intention and mission is to spearhead celiac awareness in the medical and nutrition communities as well as in the public sector. They aim to be a guiding force because up until now, support has generally come from volunteer nonprofit organizations all across the country. So, we’re looking for a little bit more of a structured single entity that can help us bring awareness much more quickly to all populations.
DR. MUSHLIN: In the multivitamin supplement, would you also want to make sure that they got some zinc?
MS. DENNIS: Yes. All the multivitamins contain zinc, but often, we need to recommend extra zinc. There’s typically not 100% of your daily recommended zinc in a multi. It’s present in trace amounts. So, if needed, we’ll check serum zinc and give zinc for 6 to 8 weeks before retesting.
DR. MUSHLIN: Dr. Leffler, let’s go quickly to the question of malignancy associated with long-standing celiac disease. In my own clinical practice experience, I’ve actually had 2 patients with celiac disease who developed non-Hodgkin’s lymphoma. Do you think there’s a definite association between malignancies and celiac disease?
DR. LEFFLER: Unfortunately, it seems like that association is clear. The overall risk of malignancy in people with celiac disease is about twofold higher than what we see in the general population. The majority of that, as you saw with your patient, is due to non-Hodgkin’s lymphoma.
There’s also an increased risk of small intestinal adenocarcinomas and small intestinal lymphomas. They’re also known as enteropathy-associated T-cell lymphomas. So, there is a significant risk.
However, we don’t screen for malignancies in patients with celiac disease any differently than we do in the general population. This is because, thankfully, the risk of malignancy drops after diagnosis, and at approximately 5 years after diagnosis, the risk is pretty close to that of the general population. So, the risk seems to be related to chronic immune activation, and once you get that immune activation under control, the risk drops. It’s a little bit of a reward that helps patients to actually follow the diet and control their disease.
DR. MUSHLIN: Well, this has been a wonderful conversation. I’ve learned a tremendous amount, and I’m very grateful to you both.
FoxP2 Media LLC is the publisher of The Medical Roundtable.
DR. LEFFLER: My name is Dr. Daniel Leffler. I’m in the Division of Gastroenterology at Beth Israel Deaconess Medical Center, and I direct the clinical research at our Celiac Center.
MS. DENNIS: My name is Melinda Dennis and I’m the nutrition coordinator of the Celiac Center at Beth Israel Deaconess Medical Center. I work with Dr. Leffler, Dr. Kelly, and the other Celiac Center gastroenterologists.
DR. MUSHLIN: Great. So, as the moderator of this conversation, I’d like to start us off with a case. This case presented to me in my primary care practice.
I saw a Harvard Medical student who came to see me regarding a stress fracture in her right foot. She was a runner and had run in 3marathons over the last 4 years. She was quite slender and had a BMI of only 19, but she quite adamantly denied being anorectic or bulimic.
She had been treated for anemia in her senior year of college with iron. She had no idea whether her anemia had improved. She had always had irregular menses since menarche, but for the past year as her running increased, she was completely amenorrheic.
After physical examination, x-ray examination revealed that she did indeed have a fracture of a metatarsal. I then obtained a bone density examination that showed osteoporosis—not just osteopenia but osteoporosis. She also had an anemia with a hematocrit of 33%, and she had microcytic hypochromic indices. I then, because of her osteoporosis, got a vitamin D level, which was definitely low. It was under 20, and that’s the lower limit of normal in our institution. She also had slightly elevated parathyroid hormone levels.
I obtained an IgA tissue transglutaminase (tTG) antibody test, and it was highly positive. I then placed her on a gluten-free diet with calcium, vitamin D, and oral iron supplementation, and that’s the case.
Dr. Leffler, would you say that this would be a pretty typical presentation of celiac disease?
DR. LEFFLER: Yes. I think all of us working with celiac disease have seen patients just like this, but it also highlights the fact that there really is no typical patient with celiac disease. A picture of what was previously considered typical involved severe malabsorptive symptoms, but that was really just scratching the tip of the iceberg for what is out there. While iron-deficiency anemia, osteoporosis, and vitamin D deficiency are very common in celiac disease, you can have all or none of these symptoms. Like this patient, you can have no gastrointestinal symptoms. Alternatively, you can have predominantly gastrointestinal symptoms.
Certainly, this patient had a number of red flags that would make you worry about celiac disease such as the early onset fracture, the osteoporosis, and the iron-deficiency anemia. Although the latter is not an uncommon thing to see in a young woman, it’s the combination of all these factors that, in my mind, would alert a clinician to the fact that these are not normal findings for a young healthy woman.
DR. MUSHLIN: If you looked at all the patients who were ultimately diagnosed with celiac disease who presented to the family practitioner or the primary care internist, what would you say would be the most common red flags? I know this case, which is a true case, had a lot of red flags, but what would be the most common symptoms that might raise your consciousness that you might be dealing with celiac disease?
DR. LEFFLER: Approximately 40% of patients with celiac disease will have chronic gastrointestinal symptoms. These can vary and can be very similar to those of irritable bowel syndrome, but gastrointestinal symptoms in the presence of a significant nutritional deficiency like iron deficiency or vitamin D deficiency, as in this case, would be very typical of celiac disease and raise a lot of red flags. A lot of these patients will also have either a personal history or a family history of other autoimmune diseases, type 1 diabetes, thyroid disease, and other similar conditions.
So, very common presentations and red flag conditions would include a patient who says, “my mother has thyroid disease” or “I have thyroid disease and now I’m iron deficient,” or “now I’m experiencing significant fatigue.” Overall, the most common presentations of celiac disease these days are gastrointestinal symptoms, iron-deficiency anemia, vitamin D deficiency, and fatigue.
DR. MUSHLIN: Certainly, all of those things are seen in an internist’s or a family practitioner’s office. I guess the real key here is that when you start to see this constellation, you should raise your consciousness that there may be one unifying diagnosis rather than multiple diagnoses.
DR. LEFFLER: Exactly. I think that the response to therapy can also be a good hint that there might be something else going on. Most young women with iron-deficiency anemia simply due to menses will do pretty well on oral iron supplementation alone. If they have severe and significant anemia and it’s just not responding to iron supplementation for instance, or if their vitamin D level is low and it does not improve with a regular dose of vitamin D, then you really have to wonder whether there is something that’s preventing absorption of this nutrient in the intestinal tract. Once you get to that level, then celiac disease is by far the most common diagnosis in these situations.
DR. MUSHLIN: We are having this colloquium here in Boston and there are a lot of people in the greater Boston area who are of Northern European extraction. Are there certain ethnic groups that have a predominance of celiac disease, or can it be found in virtually any ethnic group?
DR. LEFFLER: Earlier, we used to say this was essentially an Irish/Italian or western European disease, but now we can more easily pick out the populations that celiac disease doesn’t occur in. Celiac disease has a strong genetic predisposition with human leukocyte antigen (HLA) types, but really the populations that are at risk for celiac disease cover most of the globe: all of North and South America, Europe, the Middle East, North Africa, India, and northern China. Southeast Asians and Sub-Saharan Africans have a very low risk, but the majority of people have a significant risk of celiac disease, and I think that like all other autoimmune and inflammatory disorders, whether it’s type 1 diabetes or asthma or inflammatory bowel disease, the prevalence of celiac disease just continues to rise over time. We’re seeing it in populations that never had this disorder before.
DR. MUSHLIN: Why do you think the prevalence is increasing? Is it that our diagnostic ability is better, or do you think it’s truly increasing?
DR. LEFFLER: Well, we’ve certainly gotten a lot better at diagnosing celiac disease. You mentioned the celiac tTG antibody test earlier, which has really revolutionized the way that we diagnose celiac disease because it’s so accurate, affordable, and widespread. That being said, even in prevalence studies,1,2 there really is a dramatic increase—something in the range of a doubling—and true prevalence every 30 years or so. This is right alongside these other autoimmune and inflammatory diseases.
Clearly, nothing in our genetic heritability is changing that quickly. It’s something in the environment that is leading to an increase in the incidence of celiac disease and autoimmune diseases in general. Lots of people have theories about what that might be, and the most common theory is that we live in such a clean environment now that our immune system doesn’t have the normal feedback it needs to develop in a healthy way, and so, our immune function may start to become abnormal.
DR. MUSHLIN: This is similar to the asthma hypothesis.
DR. LEFFLER: Exactly. All of this can in some way be explained by the hygiene hypothesis.
DR. MUSHLIN: Right. When you live in Germany and the cows are housed in the same house that you live in, there’s less asthma.
DR. LEFFLER: Exactly. The same phenomenon has been seen in celiac disease in some populations, especially in northern Europe where you cross a national border and you encounter very different socioeconomic conditions. Even though you have virtually the same genetic lineage, you can have very different rates of celiac disease. I think this is very much the case.
DR. MUSHLIN: Ms. Dennis, I have a large number of patients who come into my office and say to me, “I went on a gluten-free diet and I feel so much better.” Can you address the question of gluten sensitivity versus true celiac disease? Do you feel comfortable doing that?
MS. DENNIS: Sure. We know that celiac disease is a genetic autoimmune disease, and we know that non-celiac gluten sensitivity is not considered an autoimmune disease. Dr. Leffler would be in a better position to address the issue of whether there is an inflammatory response, but there are plenty of people who come into the office confused about the 2. In order to obtain a diagnosis of non-celiac gluten sensitivity, celiac disease and wheat allergy would both need to be ruled out.
There is no positive gene testing for non-celiac gluten sensitivity, but what makes it difficult for patients is that the symptoms can mimic one another almost exactly. All the gastrointestinal symptoms, as well as some of the other extraintestinal manifestations like headaches, poor concentration, memory loss, and other similar conditions, can occur in both conditions. It’s complicated, and there is much more research that needs to be done in this area.
DR. LEFFLER: I’ll just corroborate all of that. We’ve known about celiac disease for a long time. Gluten intolerance, or non-celiac gluten sensitivity as it’s becoming more commonly known, is a very new entity that we’ve really only starting believing in, clinically at least, over the last couple of years. We’re learning about it quickly, but we still don’t have a very good sense of its prevalence.
It does appear to be a non-inflammatory disorder, which separates it from celiac disease. It doesn’t appear to have any autoimmune component and likely does not have a lot of the long-term risks associated with celiac disease such as osteoporosis or even cancer and infection risk, but at the same time, it can be associated with significant quality of life impairment, and the symptoms can mimic celiac disease. So, it is something that everyone needs to be aware of; however, while the diet-related treatment is similar, it seems that a lot of the peripheral things that we should do for our celiac patients such as getting them vaccinated and performing a bone mineral density study are not required for patients who have non-celiac gluten intolerance or gluten sensitivity. We do recommend that people work with their physicians to make a clear distinction between these 2 disorders.
DR. MUSHLIN: Just to expand on that point, would a negative tTG antibody test basically exclude celiac disease with a high degree of certainty and leave you with a diagnosis of gluten sensitivity without celiac disease (assuming the symptoms were consistent)?
DR. LEFFLER: Yes. For a typical patient who is on a regular gluten-containing diet and doesn’t have a strong family history of celiac disease or other factors that would increase risk, a negative tTG would certainly be sufficient and would imply that the chances that the patient has true celiac disease are quite low. We can then proceed with a non-celiac gluten sensitivity diagnosis and see how the patient does clinically.
DR. MUSHLIN: It seems that everywhere I go, there are more and more gluten-free choices. In fact, the wife of my closest friend here in town just started a gluten-free bakery and she’s so busy that he’s making deliveries for her now every day instead of 3 times a week. Are there any dangers to adhering to a gluten-free diet?
MS. DENNIS: There are inherent nutritional deficiencies in a gluten-free diet. So, if the diet is not proper, yes, you can lack certain vitamins and minerals. For example, wheat is a major source of protein and B vitamins as well as iron, trace minerals, and fiber.
When you switch to the gluten-free diet, you need to be able to replace those nutrients. Many people don’t focus immediately on the alternative whole and healthier gluten-free grains like amaranth, buckwheat, millet, quinoa, sorghum, and teff. They tend to move toward rice, corn, and potatoes, which tend to be lower in fiber, nutrient poor, and can cause or exacerbate constipation and weight gain when eaten in large quantities. So, that’s one of the main issues.
Additionally, we find that many people are concurrently lactose intolerant when they’re first diagnosed with celiac disease. So, we need to consider the possibility that their calcium and vitamin D intakes may be inadequate. Then, of course, we need to consider the B vitamins, which are present throughout the food chain but are present in large quantities in grains.
DR. MUSHLIN: Ms. Dennis, a lot of my patients are curious about purchasing gluten-free materials either from stores or online. Do you feel comfortable recommending any websites that you feel are legitimate for our patients to access?
Regarding consumer access, it is important to find safe gluten-free foods that are not cross-contaminated. We now have a Food Allergen Labeling and Consumer Protection Act in place that states that if wheat protein is in an FDA-regulated food, it must be labeled as such on the package. That applies to FDA foods but not USDA foods. Dieticians know the difference between these two and can educate their patients, but it’s not obvious by just reading a label.
The most obvious sources of gluten are wheat, rye, barley, malt, oats (unless they are specifically labeled and processed such that they are gluten free), and brewer’s yeast. These are easily identifiable, but it takes a little bit of education to get familiar with hidden gluten sources. One of the primary things that a person can do is make sure that their grains and flour-based products are labeled “gluten free” to help avoid some of the risks of cross-contamination that come when gluten-free grains are contaminated with wheat, rye, or barley during the farming, processing, or milling practices that typically occur in this country.
DR. MUSHLIN: So let’s say I’ve got a patient who says to me, “Doc, I’ve got celiac disease. Can I ever eat out again? Can I ever go to a restaurant?” How would you advise them?
MS. DENNIS: I have celiac disease myself, and yes you can absolutely eat out. I was diagnosed 22 years ago. So much has changed in these last 2 decades that makes life a lot easier for us, but you do have to pay attention when dining out, not only to the ingredients that are going into the food but also to the preparation technique used.
If a newly diagnosed person goes out to eat, they would want to first choose a celiac-friendly restaurant, meaning a restaurant that has a gluten-free menu. Even then, I would suggest asking questions related to the ingredients and the preparation methods. For example, it’s pretty common knowledge among people with celiac disease that fryers are contaminated, but what’s less commonly known is that scrambled eggs can often be mixed with pancake batter to make them fluffy and increase their volume. Roasts and beef cuts that are served in a restaurant are often held in a broth that contains wheat, prior to being served. Baked potatoes may be put into a fryer just before serving them at the table.
It’s important that in the kitchen, where the food is being prepared, different utensils and skillets are used, and that the person preparing the food is paying attention to what cutting boards he/she is using and not cross-contaminating with other gluten-containing products. All of this being said, there is much more opportunity for people to dine out these days. However, you have to be very, very careful, and there are resources that can lead you to restaurants that are more inclined to understand food allergies and make allowances and substitutions for those on the gluten-free diet.
DR. MUSHLIN: Ms. Dennis, would you elaborate on how to access those resources, and can you also discuss a few reputable websites that can be used by people with gluten sensitivity?
MS. DENNIS: There are a number of national organizations that are deeply committed to celiac disease, the gluten-free diet, and those with non-celiac gluten sensitivity. In no particular order, these include the Celiac Disease Foundation (www.celiac.org), the Gluten Intolerance Group (www.gluten.net), the Celiac Sprue Association of the United States (CSA/USA, Inc; www.csaceliacs.info), the American Celiac Disease Alliance (americanceliac.org), and the National Foundation for Celiac Awareness (www.celiaccentral.org). These can all be easily found by a Google search. Each of them contains multiple listings of resources including restaurants, information about dining out, tips on how to eat when traveling, nutrition information, hidden gluten sources, blogs, and how to budget on the gluten-free diet. Many of them list celiac centers across the United States and describe how to find specific clinicians who are experts in this field. All of these are reputable sites.
I should mention that we have also launched a multi-level website especially designed for the nutritional management of celiac disease: CeliacNow.org. It’s useful for anyone on the gluten-free diet as well as practitioners who want to gain more information.
Back to your original question about dining out in particular, there are 2 resources that I recommend to patients. One of them is TriumphDining.com. Not only do they list grocery stores and food sources across the state, they also list restaurants. CeceliasMarketplace.com is also another excellent website. Both of these sites also offer books on the topic. Finally, the forum at www.celiac.com is a place that most people find almost immediately when they’re diagnosed.
DR. MUSHLIN: Good. Is there any special designation for people who do nutritional work such as yourself who specialize in celiac counseling, or can any registered nutritionist counsel someone appropriately?
MS. DENNIS: They are actually working on a certification program for the counseling of patients with celiac disease. I joined a taskforce about 5 years ago that developed nutritional guidelines for the Academy of Nutrition and Dietetics.3 These guidelines are available if dieticians want to train themselves on how to counsel a patient on the gluten-free diet, beginning with the initial visit through the follow-up visits. The guidelines include laboratory tests, case studies, and multiple patient handouts, and they constitute the industry’s major educational piece on celiac disease. Beyond that, you can examine books, articles, etc, written by a number of experts in the field. There’s currently no certification.
DR. LEFFLER: A lot of patients will come to me saying, “I saw a dietician and I knew more about the diet than they did. They were no help at all.” That is really a terribly frustrating thing for patients. So, clinicians want to make sure that they send their patients to somebody who has a fair degree of knowledge, interest, and expertise in celiac disease. Unfortunately, this expertise is just not that common these days.
DR. MUSHLIN: Ms. Dennis, how many hours do you normally have to spend to get a newly diagnosed patient with true celiac disease, not just gluten sensitivity, up to speed assuming they have normal intelligence, at least a high school education, and some kind of familiarity with the basics of nutrition. How many hours might it take for you to meet with them? Often when physicians send a patient for a consultation, it’s helpful to tell the patient that they may need to be seen a few times to get it right because sometimes patients are surprised or dismayed that 20minutes with someone hasn’t fixed them.
MS. DENNIS: In this hospital setting, I’m not able to see patients as often or for as long of a period of time as I would like, and that’s common across many, many nutrition practices. We have an hour to educate patients initially. In an ideal world, the patients would be back within a few weeks for part 2 for at least an hour, and then they would check in periodically for the next 3months, 6months, and then yearly for a wellness check.
You can absolutely not do this in one session, and so, I’ve designed nutrition counseling sessions to give patients a tremendous amount of information that they can read. I also instruct them to explore reputable sites, read the material that we’ve created, and then come back with questions. I always link them to a local support group, which is absolutely critical for the management of this lifestyle adjustment. They can’t cope with the condition alone, and they certainly can’t do it on a few hours of nutrition consulting.
DR. MUSHLIN: Are you folks doing group counseling yet at your institution? For example, patients who’ve spent an hour or greater with you can come back in a group setting to get their questions answered, have an open discussion, and obtain support from other fellow patients or from other individuals following the same diet.
MS. DENNIS: Our clinic visits are one-on-one, but we do offer patient education nights 3 times a year where 10 to 40 people join us, and one of the doctors and I sit and answer questions for an hour and a half. That is a great experience for the patients. It’s always a very warm environment, and we again connect them to our larger support group that serves all of New England, the Healthy Villi, and they’re able to attend conferences, expos, or large meetings at least 3 times a year.
DR. MUSHLIN: I certainly think that if the paradigms of helping patients with chronic ongoing illness can be managed, their illnesses are going to gravitate more and more toward exactly those kinds of group support models.
MS. DENNIS: I agree.
DR. MUSHLIN: Dr. Leffler, you’ve mentioned briefly that in follow-up with your patients who have celiac disease, you need to be careful or be aware of the possibility of low bone density, and you also mentioned that they need vaccinations. What vaccinations do they require and why?
DR. LEFFLER: One of the things that is not widely known about celiac disease is that it’s actually associated with functional hyposplenism. So, people with celiac disease have an increased risk of infections—primarily those involving encapsulated organisms but also other infections—and these infections can be more severe. Our general recommendations are to vaccinate all celiac patients for flu and pneumococcus regardless of their age. Unfortunately, we have seen cases of very severe pneumococcal sepsis in otherwise totally healthy immunocompetent patients with celiac disease. So, it is something that we recommend routinely to all of our patients.
DR. MUSHLIN: Regarding the unusual association of celiac disease with other medical situations, one of my colleagues here saw a patient with pulmonary hemosiderosis who happened to have celiac disease. Are there other unusual conditions that are associated with celiac disease?
DR. LEFFLER: Yes. That pulmonary condition is called Lane-Hamilton syndrome. It is quite rare, but we’ve seen a few cases of it.
One of the fascinating things about celiac disease is that it can affect any organ system in the body. You can see effects in the central nervous system, skin, bones, kidneys, reproductive system, lungs, and heart, and there are a number of reasons why celiac disease can be so far-reaching.
Part of it is just that chronic nutritional deficiencies can lead to widespread problems, but more fundamentally, people with celiac disease produce antibodies to tTG. That’s the blood test that is most commonly ordered—the IgA anti-tTG blood test. The enzyme tTG is found in all parts of the body. Its main job is to crosslink collagen. It’s very active in wound repair and building connective tissue, and when antibodies attack this enzyme, inflammation can occur anywhere in the body. Presumably, depending on the exact type of antibodies produced and polymorphisms in tTGs, you can have a direct autoimmune effect that’s triggered in the intestine but attacks the brain or virtually any other organ.
Gluten ataxia is a cardinal well-known phenomenon where you have cerebellar inflammation and cerebellar atrophy due to the celiac reaction. You can have dermatitis herpetiformis, which is an inflammatory reaction of the skin that mostly affects extensor surfaces. So, you have this autoimmune reaction that can attack any part of the body but starts in the intestine. Once you get celiac disease under control, for example by going on a gluten-free diet, these antibody levels decrease and the autoimmune reactions cease just as they do in the intestine. This is really a very unique way of thinking about an autoimmune disease.
DR. MUSHLIN: Because we’re talking so much about antibodies, do you follow antibody titers in people you’ve placed on a gluten-free diet?
DR. LEFFLER: Yes, I do. I follow them not because they’re really wonderful at monitoring celiac disease, because they’re not. There is plenty of research including some that we’ve done ourselves4,5 that shows that they’re not great at telling, for instance, recent gluten exposure or the degree of intestinal healing. There are lots of people who have completely normal antibody levels, but their intestine’s ability to heal is significantly damaged and vice versa. Some people still have mild elevations in their antibody levels, but their intestine looks pretty good.
On the other hand, there’s really no other tool that we have, and if you have somebody with antibody levels that are persistently elevated and never drop, or drop slightly but are still 2 to 3 times the upper limit of normal, you can be fairly certain that gluten is sneaking in somewhere, and they may not know it. They may be doing their best to follow a gluten-free diet. It could be something as simple as a single generic medication or a supplement that has gluten in it that they’re taking on a daily basis. We’ve seen issues of that sort, but if their antibody level is still high, it’s very helpful as a red flag that something’s not going right.
The first thing I’ll do is send them back to see Ms. Dennis to review the diet and see where the problems are cropping up. That will fix many of the problems, but it can take an awful lot of detective work to sort through basically everything that they’re putting in their mouth and see where that bit of gluten might be.
DR. MUSHLIN: So let’s say the family practitioner diagnoses celiac disease based on the patient’s history and physical findings, and the tTG antibody test is highly positive. The practitioner then sends the patient to a nutritionist, and the patient goes on a gluten-free diet. How should that family practitioner then follow up with the patient? You mentioned immunizations—influenza yearly and Pneumovax. What else should be routinely done by that practitioner, for example, in a rural community where the patient might not have access to a specialist?
DR. LEFFLER: I want to just mention that even with a positive antibody level, endoscopy is still necessary at the beginning for diagnosis. The standard of care for celiac disease these days includes checking celiac serologies approximately every 3 to 6months until they normalize, which depends on how high they are at the beginning. Some people start off with a relative titer of 1000, and some start off with a relative titer of 50. Obviously, the latter will normalize much more quickly.
What you want to see is an improvement in those levels, so you follow them approximately every 6months until they normalize. Then you perform a celiac blood test approximately every year just to make sure that the levels are staying low and that something hasn’t changed such that the patient suddenly has an elevated level. At least 1 bone mineral density test should be performed approximately 1 year after diagnosis once their vitamin D and any other nutritional deficiencies have been repleted. We can mention the nutrients to check in a second, and if those are normal, then the patient can go back to the bone mineral density recommendations for the regular population.
If their bone mineral density is low, then you want to keep a closer eye on them depending on how low it is. You can see a lot of improvement in bone mineral density in the first year after diagnosis with celiac disease, which is why we don’t typically check bone density right off the bat unless the patient has had fractures or something that we’re really worried about. It’s only the residual osteopenia or osteoporosis that they have after a year that we would treat differently.
Even after the initial dietary counseling, we strongly recommend that patients check in with their dietician once a year. Again, a gluten-free diet is a really big change. It’s tough. Things change all the time, and by following up with a specialist, you can tell them about how the foods you eat have changed. New recommendations on a yearly basis are also recommended.
As for vitamins, the most common nutrient deficiencies in people with celiac disease are currently vitamin D, iron, and zinc. Zinc is not one that’s commonly on people’s radar, but it is actually responsible for a lot of the hair and skin manifestations that people with celiac disease complain about and potentially responsible for some of the immune dysregulation as well.
DR. LEFFLER: Correct. Sometimes we will encounter people with a normal B12level and macrocytosis, and we will wonder where that’s coming from. That’s a good thing to check. B12and folate are rarely low in people with celiac disease, so we don’t always check them.
We’ll also check liver function tests at least once in the beginning because autoimmune liver disease can be associated with celiac disease. Thyroid disease is also often associated with celiac disease, so it’s important to make sure patients have had a thyroid stimulating hormone (TSH) test at least once, and you should consider repeating that every few years. Those are the routine things that we keep an eye on in celiac disease. So, there’s a little bit of a to-do list for your patients with celiac disease.
DR. MUSHLIN: Do you ever do genetic HLA testing?
DR. LEFFLER: Yes, we do. The genetic testing for celiac disease is very interesting. Most of the genes we test for, for example those involved in hemochromatosis or cystic fibrosis, are relatively diagnostic, ie, if you have the gene, you worry that you have the disease. Celiac disease is just the opposite. The celiac genes are HLA-DQ2 and DQ8. They are actually prevalent in approximately 40% of the general population. So, they’re prerequisite genes, but they are not diagnostic genes.
If you have these genes, it means nothing because obviously the vast majority of people with these genes never get celiac disease. On the other hand, if you don’t have these genes, then you virtually cannot get celiac disease. So, these genes are helpful for 2 types of people specifically.
First, genetic testing is helpful for people who are already on a gluten-free diet and aren’t willing to do a gluten challenge. Obviously, your genes don’t change with diet, so if you get a negative genetic test, you can rule out celiac disease even while the patient is on a diet, and there’s no other way you can do that. Second, genetic testing is helpful for patients with a strong family history of celiac disease. The testing is very popular now among children whose parents have celiac disease. They have a pretty high chance of having the gene—at least 50%—but if they don’t, they’re off the hook for life, which is a nice thing to be able to tell someone. So, I think this test really does have its utility.
DR. MUSHLIN: Let’s go back to the initial diagnosis and the role of endoscopy.
DR. LEFFLER: The modern celiac blood tests, which are tTG, deamidated gliadin peptide (DGP), and endomysial antibody (EMA), are all highly accurate, have >90% sensitivity, and are specific. On the other hand, the average patient you’re going to test probably has a 5% to 10% pretest probability of celiac disease. Even the best of our tests only have a positive predictive value of approximately 80%, which means that if you rely on a serology alone, 1 out of 5 patients you diagnose with celiac disease is probably going to be a false positive. So, for that reason, because it’s a life-long diagnosis, you’re going to expose people to a lot of inconvenience to say the least as well as other medical testing, bone density analysis, and immunizations they may not need. The recommendation is still that all patients with a positive serology should follow up and get an endoscopy, which continues to be the gold standard for diagnosis.
DR. MUSHLIN: Would that be an endoscopy with a small bowel biopsy?
DR. LEFFLER: Right. A duodenal biopsy.
DR. MUSHLIN: So, depending on your population, there would be a 1in 5 chance of a false positive test. What would be the chance of a false negative test?
DR. LEFFLER: That would be well under 5% depending on the population.
DR. MUSHLIN: So, it’s 95% sensitive in picking it up, correct?
DR. LEFFLER: Right. In general, the one thing that can throw off some of these blood tests is IgA deficiency, which is a common problem that is also enriched in the celiac population. Approximately 2% of people with celiac disease have IgA deficiency, and because these blood tests are typically IgA-based, if you’re really worried about the diagnosis, you can check the total IgA level at the time of tTG measurement. If both of those are normal, and your patient is on a regular gluten-containing diet, you’re really fine in the vast majority of circumstances.
DR. MUSHLIN: In antibody testing, do you assay for endomysial antibodies in addition to transglutaminase, or do you assay for only one? Do you think that your ability to trust these tests is very dependent on the laboratory you’re using? How many of these antibody tests do you get?
DR. LEFFLER: Typically just one. There’s very little data to suggest that doing multiple tests at the same time does anything but drive up the cost. They’re all similar. They’re all typically very concordant.
So, you’re going to have one positive, and you’re going to have a second one positive. The only times I’ll consider it again are with somebody who has a borderline test and I’m considering whether or not they need an endoscopy. In that case, maybe a second one to help push me one way or the other would be helpful, but really, tTG is your workhorse. Although there are multiple assays available and almost all of them are good, I think that physicians across the country really can’t go wrong just sticking with IgA-tTG as their primary test.
DR. MUSHLIN: Terrific. Ms. Dennis, do you have anything else you want to articulate?
MS. DENNIS: Standard multivitamin mineral supplementation is a general recommendation for people with celiac disease. So, when they come into the clinic, I always recommend a gluten-free multivitamin and mineral supplement with or without iron depending on their age, gender, and laboratory values.
Sometimes our patients need vitamin B complex supplements. Sometimes it’s just a simple complaint of energy and may suggest that their B12level is lower than normal. We like to see it around 400mg/mL or above.
Calcium and vitamin D supplementation is also very common. In general, it’s difficult to get about 1200mg of calcium a day through diet alone, particularly if lactose intolerance is present. So, we often prescribe calcium supplements with vitamin D to get to that total goal.
Then, of course, Dr. Leffler was mentioning vitamin D. We recommend it based on laboratory values and diet, and almost all of our patients need vitamin D supplementation. I would also suggest that omega-3 fatty acids be considered in the dietary assessment of our patients.
DR. MUSHLIN: Why is that?
MS. DENNIS: In general, Americans aren’t getting the required amounts of omega-3 fatty acids, and eating fish is not always popular. Very few of our patients can tell me that they get approximately 6 ounces of a dark deep-water fatty fish per week, which is a general recommendation. So, if it’s necessary, I’ll suggest an omega-3supplement, but that’s always individually determined.
The last thing I wanted to mention was that just recently the North American Society for the Study of Celiac Disease was formed. It’s a clinician group, and their intention and mission is to spearhead celiac awareness in the medical and nutrition communities as well as in the public sector. They aim to be a guiding force because up until now, support has generally come from volunteer nonprofit organizations all across the country. So, we’re looking for a little bit more of a structured single entity that can help us bring awareness much more quickly to all populations.
DR. MUSHLIN: In the multivitamin supplement, would you also want to make sure that they got some zinc?
MS. DENNIS: Yes. All the multivitamins contain zinc, but often, we need to recommend extra zinc. There’s typically not 100% of your daily recommended zinc in a multi. It’s present in trace amounts. So, if needed, we’ll check serum zinc and give zinc for 6 to 8 weeks before retesting.
DR. MUSHLIN: Dr. Leffler, let’s go quickly to the question of malignancy associated with long-standing celiac disease. In my own clinical practice experience, I’ve actually had 2 patients with celiac disease who developed non-Hodgkin’s lymphoma. Do you think there’s a definite association between malignancies and celiac disease?
DR. LEFFLER: Unfortunately, it seems like that association is clear. The overall risk of malignancy in people with celiac disease is about twofold higher than what we see in the general population. The majority of that, as you saw with your patient, is due to non-Hodgkin’s lymphoma.
There’s also an increased risk of small intestinal adenocarcinomas and small intestinal lymphomas. They’re also known as enteropathy-associated T-cell lymphomas. So, there is a significant risk.
However, we don’t screen for malignancies in patients with celiac disease any differently than we do in the general population. This is because, thankfully, the risk of malignancy drops after diagnosis, and at approximately 5 years after diagnosis, the risk is pretty close to that of the general population. So, the risk seems to be related to chronic immune activation, and once you get that immune activation under control, the risk drops. It’s a little bit of a reward that helps patients to actually follow the diet and control their disease.
DR. MUSHLIN: Well, this has been a wonderful conversation. I’ve learned a tremendous amount, and I’m very grateful to you both.

The Medical Roundtable: Bone Density: Diagnosis and Management—What Is the True Burden of Disease?
Dr. Maricic, what are the different types of osteopenia that primary care clinicians encounter in their practice?
DR. MARICIC: Osteopenia has several connotations, depending on the setting in which it is diagnosed. Radiologists will describe a patient as being osteopenic based on the subjective assessment that the patient has low bone density on radiography. With particular reference to osteoporosis or bone densitometry, osteopenia refers to a dual-energy X-ray absorptiometry (DEXA) T-score, which is a comparison of the bone mass of a patient to that of a young, ideal patient of the same sex and ethnicity.
DR. GALL: Is osteoporosis the only disease or are there other diseases that we may see associated with osteopenia?
DR. MARICIC: Neither osteopenia nor osteoporosis diagnosed by the DEXA score is necessarily caused by estrogen deficiency. The DEXA report tells you whether a patient has low bone density but not about the etiology. Although estrogen deficiency is a common cause of osteopenia or osteoporosis, other conditions such as primary hyperparathyroidism, multiple myeloma, vitamin D deficiency, osteomalacia and the conditions associated with it, chronic renal failure with osteitis, fibrosis cystica, and hyperparathyroidism should be considered by the primary care physician.
It’s typically recommended that all patients with low bone density diagnosed by their DEXA score have a chemistry screening done to determine the calcium and alkaline phosphatase levels, as well as 25-hydroxy-vitamin D level, in order to ensure that the patient is not vitamin D deficient. A 24-hour urine test is also recommended to ensure that the vitamin D level is not low, suggesting malabsorption, such as what we see in vitamin D deficiency or celiac disease, or that it’s not high, suggesting idiopathic hypercalciuria.
Those are the main, most common disorders that we’d like to exclude in patients with osteopenia or especially osteoporosis. We would also want to exclude secondary hyperparathyroidism; vitamin D deficiency; and, when suspected, celiac disease, idiopathic hypercalciuria, and multiple myeloma. Those are some of the conditions to be considered, especially when the T-score does not accord with the clinical history.
DR. GALL: Dr. McClung, can you please discuss the use of X-ray and DEXA scan as diagnostic tools?
DR. MCCLUNG: These 2 tools have completely different roles. We use the DEXA scan to measure bone density, primarily in the hip and the spine, in postmenopausal women and older men to obtain a T-score that is, a value comparing the patient’s bone density to the average bone density value of young adults of the same sex. A T-score of −2.5 is thought to be consistent with osteoporosis in postmenopausal women and older men, but, as Dr. Maricic pointed out, a T-score of −2.5 only tells us that the patient has low bone density. Before we conclude that the patient has osteoporosis, all of the other causes of low bone density, including osteomalacia, osteogenesis imperfecta, and any of the secondary causes that were outlined, need to be excluded.
I believe that osteopenia, which is defined as a T-score value between −1 and −2.5, is not a very useful diagnostic term for clinical purposes. We know that low bone density is one of several risk factors for fracture. Within the group of patients with osteopenia are those who are at very high risk for fracture, including older people and those who have had fractures, as well as many patients who are not at high risk for fracture. In response to this problem, the World Health Organization developed the Fracture Risk Assessment Tool (FRAX), a fracture risk assessment tool used to help distinguish patients with high or low fracture risk.1
DR. GALL: Clinicians often find the terms used in the DEXA report confusing. Could you define absolute bone mineral density (BMD) and Z-score for the clinician?
DR. MCCLUNG: The BMD test measures the bone mineral content of a specific anatomic region and the area of that region and divides those 2 numbers to get an estimate of the BMD. It is not a true bone density test, but rather a measurement of calcium content within a region of bone.
The BMD value is translated into a T-score by comparing it to the average value for healthy young adults of the same sex and is then used for diagnosis in postmenopausal women. The Z-score is obtained by comparing the patient’s BMD value with the expected average value for healthy adults of the same age and sex and is used to determine whether a low BMD value for that patient is unexpected. A low T-score for a 55-year-old woman may be surprising, whereas a low T-score for a 90-year-old woman would be expected. A Z-score lets us know how concerned we should be.
DR. GALL: Dr. Lisse, you read a lot of DEXA scans. What can give a false value? Can you tell us about that and discuss the FRAX?
DR. LISSE: Dr. McClung wrote a very nice treatise on the FRAX,2 a tool that assesses the risk of fracture in bisphosphonate-naïve patients based on the consideration of risk factors, in addition to the BMD value. The DEXA measures bone quantity, but does not assess the risk factors for osteoporosis, of which I think prior fracture and patient age are the most important.
By considering the risk factors of smoking history, advanced age, prior fracture, and family history of fracture, and by adjusting for the country and racial origin of the patient, the FRAX provides a better measure of fracture risk for the osteopenic patient compared to BMD alone. It also provides a value, the 10-year fracture risk, that’s easier for the primary doctor to interpret compared to T-scores and Z-scores, which require comparison in terms of standard deviations.
DR. GALL: How can we use the FRAX if we are interested in doing so?
DR. LISSE: The tool is available online and very easy to use. Usually, you complete the assay using the BMD value. You can actually perform the assay without a BMD value, but I think that including the BMD value improves the precision and predictive value of the results. You just plug in the information online and are given a reading. Recent literature suggests that you can use it for patients who are taking bisphosphonates, but I think that’s a little bit further down the line in our discussion.
DR. GALL: A FRAX result states that a patient has a 10-year risk of major fracture of 8%. How do I use that result? Should I start treating the patient?
DR. LISSE: Several studies that examined local socioeconomic factors concluded that using a 20% risk of major osteoporotic fracture and a 3% risk of hip fracture are cost-effective thresholds for the diagnosis of patients in the United States. Although they should not be considered absolute, they are the current thresholds, and I think physicians can use them as criteria to make treatment decisions.
DR. MCCLUNG: That description is correct. FRAX has a scientific base and is a very highly validated tool that accurately predicts fracture probability in healthy middle-aged and older adults.1 Using the tool is a good first step while considering whether osteoporosis treatment is justified. The threshold values of a 10-year probability of hip fracture of 3% and a 10-year probability of major osteoporotic fracture of 20% are specific to the United States, which is based on the United States healthcare policy and where osteoporosis fits into the United States medical priorities. Other countries have their own thresholds that are very different.
DR. GALL: Dr. Maricic, we’ve talked about the DEXA and the FRAX. What other imaging tools are available and what are their roles?
DR. LISSE: The other issue is that the FRAX uses femoral neck density, which is a good predictor; however, in some patients, especially patients taking glucocorticoids, the spine density may be lower than the hip density. A low spine T-score should also be taken into account. We must individualize patients and not become overly focused on any one tool, although the use of the FRAX is certainly a major step forward from the use of only the T-score, for which, former guidelines recommended treatment for patients with scores within the wide range of −1 and −2.5.
DR. GALL: Another issue regarding DEXA is that we often get a false high BMD in patients with fracture of the lumbar spine, osteoarthritis, or issues with alignment of the spine. In such cases, it is important to examine the image, as the presence of bone abnormalities may render the spine DEXA score and the spine T-score less important.
DR. MARICIC: The role of other modalities in diagnosing osteoporosis in the United States is limited because of the widespread availability of DEXA in most communities. A few communities in Arizona have access to only quantitative computed tomography, which, although tends to overdiagnosise osteoporosis, can be helpful if bone density is found to be low and the clinical setting is appropriate.
Likewise, quantitative ultrasound in patients older than 65 years has a very valid role in estimating risk of fracture, but because DEXA is so widely available, we do not or usually should not use ultrasound instead of a DEXA scan and ultrasound cannot be used to monitor or follow-up patients with treatment. The only modality that should be used is the DEXA scan because of its very high precision.
DR. GALL: I have seen the use of ultrasound in both remote areas and nursing homes and other areas where it is difficult for patients to visit an office at which a DEXA scan performed, but it is not as accurate as the DEXA scan.
DR. MCCLUNG: Yes, but my understanding is that you use the ultrasound to determine whether you need a DEXA scan.
DR. MARICIC: Yes, but you shouldn’t use the ultrasound to start therapy or monitor therapy.
DR. MCCLUNG: FRAX, which can be calculated without a bone density test, provides a much more accurate assessment.
DR. MARICIC: And FRAX is probably cheaper and easier.
DR. GALL: Dr. McClung, would you talk a little bit about bone markers? I once heard you speak about their role in making a decision about when to treat patients with borderline DEXA and FRAX values.
DR. MCCLUNG: Bone markers are values obtained from blood and urine tests that reflect the activity of the bone cells. Generally, high levels of bone markers reflecting high levels of bone absorption are predictive of more rapid rates of bone loss. So, when a physician is deciding whether to treat, measuring a bone marker can sometimes provide important information to help make the decision. A bone turnover rate in the low–normal range in a bisphosphonate-naïve patient indicates that his/her bone density is stable and that he/she may benefit less from treatment compared to a patient with a high rate.
You can also use bone marker values to determine whether treatment has been effective, particularly if you use antiresorptive agents such as bisphosphonates. Patients with celiac disease or those who have had a gastrectomy may not absorb oral bisphosphonates, so their markers may remain high even if they are under treatment. Although there are certain patients for whom bone markers are helpful, the use of these markers is not routine in the management of most patients with osteoporosis.
DR. GALL: I would say that bone markers are generally overused. Another area in which the use of bone marker values may be helpful is compliance. I’ve used bone biomarker values in cases in which, for example, I start a patient on a weekly bisphosphonate and the patient comes back 12 weeks later saying that he/she doesn’t need a prescription. In such cases, I may perform bone marker testing to see whether the patient has been compliant.
Is there ever a time when we need to do a bone biopsy?
DR. MARICIC: I think a bone biopsy is only helpful for patients with long-term renal failure and dialysis to separate out the various forms of renal osteodystrophy. Although we used to perform a biopsy to help us understand bone turnover or detect osteomalacia, we can now do both with a biochemical test.
In some cases, we want to perform a bone marrow biopsy to look for marrow-based diseases such as mastocytosis or myeloma.
DR. GALL: I’d now like to discuss the prevention of osteoporosis and the risk factors that indicate testing and treatment of patients who are not postmenopausal.
DR. LISSE: There are risk factors that are nonmodifiable, including family history and genetics; modifiable risk factors, including level of exercise, especially weight-bearing exercise, which can be decreased; smoking, which can be discontinued or at least attenuated; and alcohol intake, which can be decreased. I think the role of caffeine is still controversial, although I’d love to hear from the other members of the panel about that.
I think we have overemphasized the importance of calcium and vitamin D supplementation. However, I measure the serum 25-hydroxy-vitamin D level, which according to me, is becoming more and more popular, and I try to keep it at around 30 ng/mL. I think all female patients should obtain some calcium supplementation, especially if their dietary intake is not adequate.
It was surprising to know that there’s probably a higher prevalence of vitamin D insufficiency in Arizona than in Minnesota in spite of the abundance of sunshine in the former.
DR. GALL: I consider patients who are thin, have poor bone stock, are malnourished, did not drink milk in their childhood, and have a family history of hip fracture in a close relative to be at higher risk, and I tend to test them early and consider either preventative treatment or just treatment for them.
I think an appropriate target for daily intake of calcium is between 800 and 1 200 mg, including that obtained from diet. The appropriate target for vitamin D intake in the absence of regular sun exposure is between 600 and 2 000 units per day.
DR. LISSE: Most recommendations that I’ve seen for calcium are about 800 mg, but they vary widely.
DR. MCCLUNG: Let’s get back to the management of premenopausal women with risk factors for low bone mass such as small body size, family history of osteoporosis, and medical problems that may lead to impaired bone health such as amenorrhea during early adolescence. For these women, maintaining adequate nutrition and physical activity and avoiding harmful lifestyle factors should be encouraged, but bone density testing is rarely necessary. If premenopausal women are estrogen replete, even if they have low bone density, treatment with osteoporosis drugs is not recommended. Individuals with risk factors for low bone density should be screened at the time of menopause to decide whether aggressive prevention of the rapid bone loss that occurs at that particularly important time is warranted.
DR. GALL: Dr. Maricic, there are 2 topics I’d like you to discuss. The first is comorbidities, specifically conditions such as thyroid disease, that we need to pay attention to, and the second is hormone replacement therapy and its current role.
DR. MARICIC: The NOF guidelines for the diagnosis and treatment of osteoporosis5 list a number of comorbid disorders and medications that may be responsible for a patient’s low bone density. We should consider the potential for osteoporosis in all men and women over the age of 50 years, especially if they have other disorders or medications known to affect bone mineral metabolism.
The NOF guidelines list about 30 diseases implicated in low bone density, including type 2 diabetes, hemochromatosis, and androgen- and estrogen-deficiency hypogonadism. Low bone density should be considered in patients with gastrointestinal (GI) disorders, of which celiac disease is the most important and common; those who have undergone GI bypass or other types of GI surgery; and those with hematological disorders such as mastocytosis and myeloma. Because chronic inflammatory production of cytokines and calcium immobilization lead to accelerated bone loss, low bone density should be considered in patients with rheumatic disorders, including systemic lupus; ankylosing spondylitis; and especially, rheumatoid arthritis, which FRAX identifies as a major risk factor for accelerated bone loss. Finally, low bone density should be considered in patients with a number of miscellaneous conditions, including chronic obstructive pulmonary disease, emphysema, chronic asthma, and sarcoidosis.
Regarding medications, the agents most commonly associated with low bone density are glucocorticoids. Low bone density should also be considered in patients taking certain anticonvulsants, especially phenobarbital and phenytoin, which can lead to accelerated degradation of 25-hydroxy-vitamin D and very low vitamin D levels and consequent osteomalacia, and in those taking aromatase inhibitors, which are now very important in the treatment of breast cancer.
DR. GALL: I’d just like to mention again the association between low bone density and both thyroid disease and overmedication in thyroid replacement therapy.
DR. MCCLUNG: We should probably also include proton pump inhibitors and selective serotonin reuptake inhibitors, which have been correlated with increased rates of fracture, although the mechanism underlying that correlation is unclear.
DR. LISSE: Do you mean that their wide use poses a concern?
DR. MCCLUNG: Yes, but their effect does not seem to be reflected in bone density testing. So, while recognizing their use as an independent risk factor for fracture is important, it is still unclear whether it should be considered while deciding whether to treat with an osteoporosis drug.
DR. MARICIC: Regarding hormone replacement therapy, we must first distinguish between hormone replacement, which is a combination of estrogen and progesterone for women with an intact uterus, and estrogen replacement or estrogen therapy, which is estrogen alone for women who have undergone a hysterectomy. Definitely, there are differences in the potential for adverse effects between these 2 groups.
I believe the data from the Women’s Health Initiative (WHI) suggested that increased risk of thrombosis and breast cancer is more commonly seen with hormone therapy and may be due more to progesterone than to estrogen replacement.6 There are also some differences in the risk with regard to the age of starting hormone therapy in our patients.
From the WHI, we know that hormone therapy prevents bone loss and reduces the risk of hip and other fractures. I think hormone therapy, especially estrogen therapy for women with an intact uterus, is an option to protect the skeleton in women with low bone density, especially those who are perimenopausal or early postmenopausal.
I personally avoid starting hormone therapy in patients above the age of 70 years and sometimes even above 65 years, but I believe it can be an option for women between the ages of 50 and 60 years with low bone density and no contraindications. For women with a strong family history of breast cancer, I usually recommend raloxifene. We’re now trying to limit the lifetime exposure of women to bisphosphonates, so I tend to reserve them for older women at very high risk of fracture, and almost never administer them to women aged 50 to 60 years.
I think that hormone therapy is the first option for women between 50 and 60 years with no strong family history of breast cancer. If there is, I start them on Evista, when possible.
DR. LISSE: I think that bisphosphonate therapy has been the primary choice of osteoporosis therapy since at least 2 000, which is when alendronate came into the market under its brand name. These drugs have been shown to reliably decrease fracture and improve the quality of life. Some drugs, particularly zoledronic acid, actually decrease mortality in patients with hip fracture.7
There are some differences among them. The first one on the market obviously was alendronate, so there’s probably the most data on it. Risedronate, alendronate, zoledronic acid, denosumab, and teriparatide have been shown to reduce vertebral and nonvertebral fracture; ibandronate, to reduce spinal but not nonvertebral fracture; alendronate, risedronate, denosumab, and zoledronic acid, to prevent hip fracture in postmenopausal women; and risedronate, to decrease vertebral and nonvertebral fracture in men.7
The original studies on the effect of many of these drugs on fracture risk were conducted with daily dosing, and equivalent dosing in weekly and monthly regimens has been used and approved, sometimes without fracture data. The drugs work, their safety-to-risk ratio is quite good, and we have long-term experience with them. I think it’s not surprising that a small percentage of patients who have been on them for a decade or more have issues and side effects. There are risks to taking these drugs, as there are with any other drug.
Probably, the most common risk is GI complications, ranging from irritation to esophageal perforation, which surfaced shortly after alendronate came on the market. To prevent GI complications, strict regimens have been developed for oral bisphosphonate use. To some extent, I think that they limit our patient population because many cannot or will not comply with the requirement of taking the drug first thing in the morning on an empty stomach with approximately 230 mL of water and remain upright for 30 to 60 minutes, depending on the medication, to realize any benefit.
Gastrointestinal complications, including those affecting the esophagus, are, by far, the most common issues observed with bisphosphonate therapy. Gastric ulcerations in certain patients, especially in those who use risedronate in coated form, have also been observed.
There are other probably less common but controversial issues, including a possible association with atrial fibrillation, which was identified in the Health Outcomes and Reduced Incidence with Zoledronic Acid Once Yearly (HORIZON) study.8 An association with alendronate was also suspected, but a recent meta-analysis does not support this association.9
An association with esophageal cancer has been anecdotally described in several populations, but I think that the data are mixed at this point. Then, there is the association with osteonecrosis of the jaw and atypical fracture, both of which are quite rare and occur in between 1 in 10 000 to 1 in 100 000 patients.10 I think that the wide coverage of this association in the lay press may have caused many patients who probably shouldn’t have gone off bisphosphonates, to go off them.
A positive byproduct of these associations being reported could be increased research into whether there should be a time or exposure limit to bisphosphonate use and whether a drug holiday from them is warranted.
DR. GALL: Dr. McClung, could you please describe how you monitor a patient after initiation of bisphosphonate therapy and then discuss an atypical fracture?
DR. MCCLUNG: Treatment with any osteoporosis drug is generally monitored by measuring BMD 2 years after the patient has started therapy. The changes in BMD with treatment are quite modest, so we expect to see either a modest increase or at least stability. If a clear decrease in BMD is observed, we consider noncompliance, secondary causes of bone loss, and other reasons for treatment failure.
In theory, biochemical testing of bone turnover should be useful in monitoring therapy. However, because of limitations in the quality and the reproducibility of the assays in the clinical setting, it is difficult to use the results. I think that marker measurement is not ready for use in the everyday clinic, although it has been very valuable in our research.
Atypical fracture is important. As mentioned earlier, there has been concern right from the time when bisphosphonate research began about the potential for skeletal consequences with long-term therapy because of the pharmacology of bisphosphonates. We know that these drugs accumulate in the skeleton over time, and there were concerns about whether we would see progressive inhibition of bone turnover with long-term therapy. Although we were pleased to observe persistent, but not progressive, reduction in bone turnover with long-term treatment, at least for up to 10 years,11 it appears that some individuals, or perhaps, a unique subset of patients, experience too much inhibition of bone metabolism for prolonged durations. When this happens, bone brittleness occurs and is manifested by atypical chalk stick-like fractures of the femur. It is clear that there is a duration-dependent increase in risk, with fractures occurring in roughly 1 in 1 000 patients who have completed at least 10 years of alendronate therapy.12 If we properly decide whom to treat and how to treat, it is important to recognize that this risk is much, much lower than the risk of important fracture, such as that of the hip and spine, in patients who are not treated with bisphosphonate therapy.13 We should reserve bisphosphonates for patients who clearly have osteoporosis or are at high risk for fracture.
DR. GALL: Dr. Maricic, can you conclude on the use of calcitonin, denosumab, and teriparatide, ie, some of the other drugs approved for the treatment of osteoporosis?
DR. MARICIC: Calcitonin is extremely safe but it isn’t very effective and has been shown to reduce spinal fracture risk by 33% and have no effect on hip fracture risk,14 so I personally haven’t prescribed it in almost 10 years.
Denosumab, a receptor activator of nuclear factor-kB (RANK)-ligand inhibitor and monoclonal antibody, is probably among the most effective medications we have. Because it bypasses the GI tract, it’s an excellent choice for patients who develop GI problems with bisphosphonates. Nevertheless, because it is a very potent osteoclast inhibitor, it must be used carefully in patients prone to hypocalcemia, with renal failure, or who are extremely vitamin D deficient. Although hypocalcemia must be considered before initiating its use, I think it is an extremely effective agent.
Teriparatide is the only anabolic agent currently approved for use in patients at high risk of fracture, and that’s for whom we mainly use it. Because its mode of action is completely different from that of bisphosphonates, we use it for patients with either very low bone density or with multiple fractures who have not responded to bisphosphonate therapy. The Food and Drug Administration (FDA) has approved teriparatide therapy for only 2 years, after which it must be followed by antiresorptive therapy. Unfortunately, I occasionally see patients who had not been given antiresorptives after 2 years of teriparatide, causing them to lose any benefit they may have derived from being on this very expensive drug for 2 years. It must always be followed up by an antiresorptive drug.
DR. MCCLUNG: Regarding a drug holiday, you can consider it if you observe a duration-dependent increase in the risk of atypical fracture.15,16 The FDA has provided us with at least a general template for when it should be considered.17 Based on the limited information we have, it is suggested that fracture risk be reassessed after 3 to 5 years of therapy. For patients with a modest risk for fracture at that point, ie, they no longer have osteoporosis according to the results of bone density testing, it is suggested that therapy be discontinued for 1 to 2 years.
For patients found to remain at high risk for fracture, especially spine fracture, continuation of therapy is recommended. The evidence for this recommendation came from 2 large extension studies of the alendronate and zoledronic acid clinical trials.18,19
If treatment is discontinued, the question of when, if ever, to restart therapy arises. The data from the clinical trials suggest that neither the measurement of bone density nor bone markers are helpful in that regard. So, in my clinic, we treat the holiday like a vacation that has a finite end.13 We take patients off alendronate for 2 or 3 years but off risedronate for only 1 year because its effects wear off more quickly. At that point, we reassess the patient. If he/she meets the criteria for treatment with an osteoporosis drug again, we decide on the best treatment option.
DR. GALL: Dr. Lisse, please describe how treating steroid-induced male osteoporosis differs from treating postmenopausal and female osteoporosis.
DR. LISSE: Before I do so, I wanted to add that a flu-like syndrome sometimes occurs with bisphosphonate use. In a corollary to what Dr. McClung just discussed, the European registries provide at least some reassuring evidence that when patients stop taking bisphosphonates, the risk of atypical fracture appears to decrease fairly rapidly, whereas bisphosphonate efficacy doesn’t seem to tail off as quickly.15 It should be reassuring that if patients stop taking a drug, they may have some protection during that period in terms of osteoporosis coverage, unlike when they stop taking estrogen or teriparatide, whose effects tail off rather rapidly.
With glucocorticoid-induced osteoporosis, the biggest issue is probably the fact that fractures tend to occur early and at a higher bone density than what we’re used to seeing with traditional postmenopausal osteoporosis. So it has thrown the old paradigm into disarray. Before the introduction of FRAX, treatment was recommended for patients with a T-score of −1. As the FRAX includes glucocorticoids as a risk factor, its use is very helpful in this regard.
FRAX does have its limitations, and there are physicians who are concerned that it does not include consideration of steroid duration or dose. I think the American College of Rheumatology’s recommendation is to measure bone density and then subdivide the patient population into low risk, moderate risk, and high risk according to the risk for major osteoporotic fracture of ≤10%, 10% to 20%, and ≥20%, respectively.20 Treatment should be considered based on the risk and dosage. Patients taking a dose of 7.5 mg or higher probably need treatment, even if they’re at low risk. Patients on lower doses probably need treatment if they remain on glucocorticoid therapy for more than 3 months.
Although most fractures due to steroid use are of the spine, not all are. I’m sure all of us on the panel are old enough to remember the old asthmatics who used to take large doses of steroids. Certainly, one of the easiest things to do is to taper patients off steroids or reduce the dose down to the lowest possible dose. The use of topical steroids is preferred to that of oral steroids or inhaled steroids.
The NOF guidelines for testing for male osteoporosis differ from those for testing female osteoporosis. Although they recommend that all women older than 65 years be tested, they do not recommend routine testing in men older than 70 years. I think that this latter recommendation, which is based on a US Preventative Health Service Task Force recommendation,21 is probably a mistake and rather confusing.
Even though there has been a study of raloxifene in men, the guidelines are more limited regarding how men who are hypogonadal should be treated. Testosterone should be measured in all men, and those found to be hypogonadal deserve testosterone replacement. Again, the backbone of therapy is the use of bisphosphonates for the most part. Teriparatide has also been approved for use in men, although it has not been proven to provide protection against hip fracture.
DR. GALL: We’ve had an extensive discussion today on low bone density diseases, focusing mostly on osteoporosis. We have discussed at some length the risk factors and the diagnostic tools that we have, particularly the DEXA scan and FRAX, to assess the risk of fracture. We then discussed the risk factors, including comorbidities; means of prevention; and the different treatment modalities, including physical therapy and several nonpharmacologic therapies, in addition to the various medical therapies, including hormone replacement, bisphosphonates, calcitonin, denosumab, and teriparatide. We’ve also briefly touched on the differences between postmenopausal osteoporosis and steroid-induced osteoporosis and male osteoporosis.

Dr. Maricic, what are the different types of osteopenia that primary care clinicians encounter in their practice?
DR. MARICIC: Osteopenia has several connotations, depending on the setting in which it is diagnosed. Radiologists will describe a patient as being osteopenic based on the subjective assessment that the patient has low bone density on radiography. With particular reference to osteoporosis or bone densitometry, osteopenia refers to a dual-energy X-ray absorptiometry (DEXA) T-score, which is a comparison of the bone mass of a patient to that of a young, ideal patient of the same sex and ethnicity.
DR. GALL: Is osteoporosis the only disease or are there other diseases that we may see associated with osteopenia?
DR. MARICIC: Neither osteopenia nor osteoporosis diagnosed by the DEXA score is necessarily caused by estrogen deficiency. The DEXA report tells you whether a patient has low bone density but not about the etiology. Although estrogen deficiency is a common cause of osteopenia or osteoporosis, other conditions such as primary hyperparathyroidism, multiple myeloma, vitamin D deficiency, osteomalacia and the conditions associated with it, chronic renal failure with osteitis, fibrosis cystica, and hyperparathyroidism should be considered by the primary care physician.
It’s typically recommended that all patients with low bone density diagnosed by their DEXA score have a chemistry screening done to determine the calcium and alkaline phosphatase levels, as well as 25-hydroxy-vitamin D level, in order to ensure that the patient is not vitamin D deficient. A 24-hour urine test is also recommended to ensure that the vitamin D level is not low, suggesting malabsorption, such as what we see in vitamin D deficiency or celiac disease, or that it’s not high, suggesting idiopathic hypercalciuria.
Those are the main, most common disorders that we’d like to exclude in patients with osteopenia or especially osteoporosis. We would also want to exclude secondary hyperparathyroidism; vitamin D deficiency; and, when suspected, celiac disease, idiopathic hypercalciuria, and multiple myeloma. Those are some of the conditions to be considered, especially when the T-score does not accord with the clinical history.
DR. GALL: Dr. McClung, can you please discuss the use of X-ray and DEXA scan as diagnostic tools?
DR. MCCLUNG: These 2 tools have completely different roles. We use the DEXA scan to measure bone density, primarily in the hip and the spine, in postmenopausal women and older men to obtain a T-score that is, a value comparing the patient’s bone density to the average bone density value of young adults of the same sex. A T-score of −2.5 is thought to be consistent with osteoporosis in postmenopausal women and older men, but, as Dr. Maricic pointed out, a T-score of −2.5 only tells us that the patient has low bone density. Before we conclude that the patient has osteoporosis, all of the other causes of low bone density, including osteomalacia, osteogenesis imperfecta, and any of the secondary causes that were outlined, need to be excluded.
I believe that osteopenia, which is defined as a T-score value between −1 and −2.5, is not a very useful diagnostic term for clinical purposes. We know that low bone density is one of several risk factors for fracture. Within the group of patients with osteopenia are those who are at very high risk for fracture, including older people and those who have had fractures, as well as many patients who are not at high risk for fracture. In response to this problem, the World Health Organization developed the Fracture Risk Assessment Tool (FRAX), a fracture risk assessment tool used to help distinguish patients with high or low fracture risk.1
DR. GALL: Clinicians often find the terms used in the DEXA report confusing. Could you define absolute bone mineral density (BMD) and Z-score for the clinician?
DR. MCCLUNG: The BMD test measures the bone mineral content of a specific anatomic region and the area of that region and divides those 2 numbers to get an estimate of the BMD. It is not a true bone density test, but rather a measurement of calcium content within a region of bone.
The BMD value is translated into a T-score by comparing it to the average value for healthy young adults of the same sex and is then used for diagnosis in postmenopausal women. The Z-score is obtained by comparing the patient’s BMD value with the expected average value for healthy adults of the same age and sex and is used to determine whether a low BMD value for that patient is unexpected. A low T-score for a 55-year-old woman may be surprising, whereas a low T-score for a 90-year-old woman would be expected. A Z-score lets us know how concerned we should be.
DR. GALL: Dr. Lisse, you read a lot of DEXA scans. What can give a false value? Can you tell us about that and discuss the FRAX?
DR. LISSE: Dr. McClung wrote a very nice treatise on the FRAX,2 a tool that assesses the risk of fracture in bisphosphonate-naïve patients based on the consideration of risk factors, in addition to the BMD value. The DEXA measures bone quantity, but does not assess the risk factors for osteoporosis, of which I think prior fracture and patient age are the most important.
By considering the risk factors of smoking history, advanced age, prior fracture, and family history of fracture, and by adjusting for the country and racial origin of the patient, the FRAX provides a better measure of fracture risk for the osteopenic patient compared to BMD alone. It also provides a value, the 10-year fracture risk, that’s easier for the primary doctor to interpret compared to T-scores and Z-scores, which require comparison in terms of standard deviations.
DR. GALL: How can we use the FRAX if we are interested in doing so?
DR. LISSE: The tool is available online and very easy to use. Usually, you complete the assay using the BMD value. You can actually perform the assay without a BMD value, but I think that including the BMD value improves the precision and predictive value of the results. You just plug in the information online and are given a reading. Recent literature suggests that you can use it for patients who are taking bisphosphonates, but I think that’s a little bit further down the line in our discussion.
DR. GALL: A FRAX result states that a patient has a 10-year risk of major fracture of 8%. How do I use that result? Should I start treating the patient?
DR. LISSE: Several studies that examined local socioeconomic factors concluded that using a 20% risk of major osteoporotic fracture and a 3% risk of hip fracture are cost-effective thresholds for the diagnosis of patients in the United States. Although they should not be considered absolute, they are the current thresholds, and I think physicians can use them as criteria to make treatment decisions.
DR. MCCLUNG: That description is correct. FRAX has a scientific base and is a very highly validated tool that accurately predicts fracture probability in healthy middle-aged and older adults.1 Using the tool is a good first step while considering whether osteoporosis treatment is justified. The threshold values of a 10-year probability of hip fracture of 3% and a 10-year probability of major osteoporotic fracture of 20% are specific to the United States, which is based on the United States healthcare policy and where osteoporosis fits into the United States medical priorities. Other countries have their own thresholds that are very different.
DR. GALL: Dr. Maricic, we’ve talked about the DEXA and the FRAX. What other imaging tools are available and what are their roles?
DR. LISSE: The other issue is that the FRAX uses femoral neck density, which is a good predictor; however, in some patients, especially patients taking glucocorticoids, the spine density may be lower than the hip density. A low spine T-score should also be taken into account. We must individualize patients and not become overly focused on any one tool, although the use of the FRAX is certainly a major step forward from the use of only the T-score, for which, former guidelines recommended treatment for patients with scores within the wide range of −1 and −2.5.
DR. GALL: Another issue regarding DEXA is that we often get a false high BMD in patients with fracture of the lumbar spine, osteoarthritis, or issues with alignment of the spine. In such cases, it is important to examine the image, as the presence of bone abnormalities may render the spine DEXA score and the spine T-score less important.
DR. MARICIC: The role of other modalities in diagnosing osteoporosis in the United States is limited because of the widespread availability of DEXA in most communities. A few communities in Arizona have access to only quantitative computed tomography, which, although tends to overdiagnosise osteoporosis, can be helpful if bone density is found to be low and the clinical setting is appropriate.
Likewise, quantitative ultrasound in patients older than 65 years has a very valid role in estimating risk of fracture, but because DEXA is so widely available, we do not or usually should not use ultrasound instead of a DEXA scan and ultrasound cannot be used to monitor or follow-up patients with treatment. The only modality that should be used is the DEXA scan because of its very high precision.
DR. GALL: I have seen the use of ultrasound in both remote areas and nursing homes and other areas where it is difficult for patients to visit an office at which a DEXA scan performed, but it is not as accurate as the DEXA scan.
DR. MCCLUNG: Yes, but my understanding is that you use the ultrasound to determine whether you need a DEXA scan.
DR. MARICIC: Yes, but you shouldn’t use the ultrasound to start therapy or monitor therapy.
DR. MCCLUNG: FRAX, which can be calculated without a bone density test, provides a much more accurate assessment.
DR. MARICIC: And FRAX is probably cheaper and easier.
DR. GALL: Dr. McClung, would you talk a little bit about bone markers? I once heard you speak about their role in making a decision about when to treat patients with borderline DEXA and FRAX values.
DR. MCCLUNG: Bone markers are values obtained from blood and urine tests that reflect the activity of the bone cells. Generally, high levels of bone markers reflecting high levels of bone absorption are predictive of more rapid rates of bone loss. So, when a physician is deciding whether to treat, measuring a bone marker can sometimes provide important information to help make the decision. A bone turnover rate in the low–normal range in a bisphosphonate-naïve patient indicates that his/her bone density is stable and that he/she may benefit less from treatment compared to a patient with a high rate.
You can also use bone marker values to determine whether treatment has been effective, particularly if you use antiresorptive agents such as bisphosphonates. Patients with celiac disease or those who have had a gastrectomy may not absorb oral bisphosphonates, so their markers may remain high even if they are under treatment. Although there are certain patients for whom bone markers are helpful, the use of these markers is not routine in the management of most patients with osteoporosis.
DR. GALL: I would say that bone markers are generally overused. Another area in which the use of bone marker values may be helpful is compliance. I’ve used bone biomarker values in cases in which, for example, I start a patient on a weekly bisphosphonate and the patient comes back 12 weeks later saying that he/she doesn’t need a prescription. In such cases, I may perform bone marker testing to see whether the patient has been compliant.
Is there ever a time when we need to do a bone biopsy?
DR. MARICIC: I think a bone biopsy is only helpful for patients with long-term renal failure and dialysis to separate out the various forms of renal osteodystrophy. Although we used to perform a biopsy to help us understand bone turnover or detect osteomalacia, we can now do both with a biochemical test.
In some cases, we want to perform a bone marrow biopsy to look for marrow-based diseases such as mastocytosis or myeloma.
DR. GALL: I’d now like to discuss the prevention of osteoporosis and the risk factors that indicate testing and treatment of patients who are not postmenopausal.
DR. LISSE: There are risk factors that are nonmodifiable, including family history and genetics; modifiable risk factors, including level of exercise, especially weight-bearing exercise, which can be decreased; smoking, which can be discontinued or at least attenuated; and alcohol intake, which can be decreased. I think the role of caffeine is still controversial, although I’d love to hear from the other members of the panel about that.
I think we have overemphasized the importance of calcium and vitamin D supplementation. However, I measure the serum 25-hydroxy-vitamin D level, which according to me, is becoming more and more popular, and I try to keep it at around 30 ng/mL. I think all female patients should obtain some calcium supplementation, especially if their dietary intake is not adequate.
It was surprising to know that there’s probably a higher prevalence of vitamin D insufficiency in Arizona than in Minnesota in spite of the abundance of sunshine in the former.
DR. GALL: I consider patients who are thin, have poor bone stock, are malnourished, did not drink milk in their childhood, and have a family history of hip fracture in a close relative to be at higher risk, and I tend to test them early and consider either preventative treatment or just treatment for them.
I think an appropriate target for daily intake of calcium is between 800 and 1 200 mg, including that obtained from diet. The appropriate target for vitamin D intake in the absence of regular sun exposure is between 600 and 2 000 units per day.
DR. LISSE: Most recommendations that I’ve seen for calcium are about 800 mg, but they vary widely.
DR. MCCLUNG: Let’s get back to the management of premenopausal women with risk factors for low bone mass such as small body size, family history of osteoporosis, and medical problems that may lead to impaired bone health such as amenorrhea during early adolescence. For these women, maintaining adequate nutrition and physical activity and avoiding harmful lifestyle factors should be encouraged, but bone density testing is rarely necessary. If premenopausal women are estrogen replete, even if they have low bone density, treatment with osteoporosis drugs is not recommended. Individuals with risk factors for low bone density should be screened at the time of menopause to decide whether aggressive prevention of the rapid bone loss that occurs at that particularly important time is warranted.
DR. GALL: Dr. Maricic, there are 2 topics I’d like you to discuss. The first is comorbidities, specifically conditions such as thyroid disease, that we need to pay attention to, and the second is hormone replacement therapy and its current role.
DR. MARICIC: The NOF guidelines for the diagnosis and treatment of osteoporosis5 list a number of comorbid disorders and medications that may be responsible for a patient’s low bone density. We should consider the potential for osteoporosis in all men and women over the age of 50 years, especially if they have other disorders or medications known to affect bone mineral metabolism.
The NOF guidelines list about 30 diseases implicated in low bone density, including type 2 diabetes, hemochromatosis, and androgen- and estrogen-deficiency hypogonadism. Low bone density should be considered in patients with gastrointestinal (GI) disorders, of which celiac disease is the most important and common; those who have undergone GI bypass or other types of GI surgery; and those with hematological disorders such as mastocytosis and myeloma. Because chronic inflammatory production of cytokines and calcium immobilization lead to accelerated bone loss, low bone density should be considered in patients with rheumatic disorders, including systemic lupus; ankylosing spondylitis; and especially, rheumatoid arthritis, which FRAX identifies as a major risk factor for accelerated bone loss. Finally, low bone density should be considered in patients with a number of miscellaneous conditions, including chronic obstructive pulmonary disease, emphysema, chronic asthma, and sarcoidosis.
Regarding medications, the agents most commonly associated with low bone density are glucocorticoids. Low bone density should also be considered in patients taking certain anticonvulsants, especially phenobarbital and phenytoin, which can lead to accelerated degradation of 25-hydroxy-vitamin D and very low vitamin D levels and consequent osteomalacia, and in those taking aromatase inhibitors, which are now very important in the treatment of breast cancer.
DR. GALL: I’d just like to mention again the association between low bone density and both thyroid disease and overmedication in thyroid replacement therapy.
DR. MCCLUNG: We should probably also include proton pump inhibitors and selective serotonin reuptake inhibitors, which have been correlated with increased rates of fracture, although the mechanism underlying that correlation is unclear.
DR. LISSE: Do you mean that their wide use poses a concern?
DR. MCCLUNG: Yes, but their effect does not seem to be reflected in bone density testing. So, while recognizing their use as an independent risk factor for fracture is important, it is still unclear whether it should be considered while deciding whether to treat with an osteoporosis drug.
DR. MARICIC: Regarding hormone replacement therapy, we must first distinguish between hormone replacement, which is a combination of estrogen and progesterone for women with an intact uterus, and estrogen replacement or estrogen therapy, which is estrogen alone for women who have undergone a hysterectomy. Definitely, there are differences in the potential for adverse effects between these 2 groups.
I believe the data from the Women’s Health Initiative (WHI) suggested that increased risk of thrombosis and breast cancer is more commonly seen with hormone therapy and may be due more to progesterone than to estrogen replacement.6 There are also some differences in the risk with regard to the age of starting hormone therapy in our patients.
From the WHI, we know that hormone therapy prevents bone loss and reduces the risk of hip and other fractures. I think hormone therapy, especially estrogen therapy for women with an intact uterus, is an option to protect the skeleton in women with low bone density, especially those who are perimenopausal or early postmenopausal.
I personally avoid starting hormone therapy in patients above the age of 70 years and sometimes even above 65 years, but I believe it can be an option for women between the ages of 50 and 60 years with low bone density and no contraindications. For women with a strong family history of breast cancer, I usually recommend raloxifene. We’re now trying to limit the lifetime exposure of women to bisphosphonates, so I tend to reserve them for older women at very high risk of fracture, and almost never administer them to women aged 50 to 60 years.
I think that hormone therapy is the first option for women between 50 and 60 years with no strong family history of breast cancer. If there is, I start them on Evista, when possible.
DR. LISSE: I think that bisphosphonate therapy has been the primary choice of osteoporosis therapy since at least 2 000, which is when alendronate came into the market under its brand name. These drugs have been shown to reliably decrease fracture and improve the quality of life. Some drugs, particularly zoledronic acid, actually decrease mortality in patients with hip fracture.7
There are some differences among them. The first one on the market obviously was alendronate, so there’s probably the most data on it. Risedronate, alendronate, zoledronic acid, denosumab, and teriparatide have been shown to reduce vertebral and nonvertebral fracture; ibandronate, to reduce spinal but not nonvertebral fracture; alendronate, risedronate, denosumab, and zoledronic acid, to prevent hip fracture in postmenopausal women; and risedronate, to decrease vertebral and nonvertebral fracture in men.7
The original studies on the effect of many of these drugs on fracture risk were conducted with daily dosing, and equivalent dosing in weekly and monthly regimens has been used and approved, sometimes without fracture data. The drugs work, their safety-to-risk ratio is quite good, and we have long-term experience with them. I think it’s not surprising that a small percentage of patients who have been on them for a decade or more have issues and side effects. There are risks to taking these drugs, as there are with any other drug.
Probably, the most common risk is GI complications, ranging from irritation to esophageal perforation, which surfaced shortly after alendronate came on the market. To prevent GI complications, strict regimens have been developed for oral bisphosphonate use. To some extent, I think that they limit our patient population because many cannot or will not comply with the requirement of taking the drug first thing in the morning on an empty stomach with approximately 230 mL of water and remain upright for 30 to 60 minutes, depending on the medication, to realize any benefit.
Gastrointestinal complications, including those affecting the esophagus, are, by far, the most common issues observed with bisphosphonate therapy. Gastric ulcerations in certain patients, especially in those who use risedronate in coated form, have also been observed.
There are other probably less common but controversial issues, including a possible association with atrial fibrillation, which was identified in the Health Outcomes and Reduced Incidence with Zoledronic Acid Once Yearly (HORIZON) study.8 An association with alendronate was also suspected, but a recent meta-analysis does not support this association.9
An association with esophageal cancer has been anecdotally described in several populations, but I think that the data are mixed at this point. Then, there is the association with osteonecrosis of the jaw and atypical fracture, both of which are quite rare and occur in between 1 in 10 000 to 1 in 100 000 patients.10 I think that the wide coverage of this association in the lay press may have caused many patients who probably shouldn’t have gone off bisphosphonates, to go off them.
A positive byproduct of these associations being reported could be increased research into whether there should be a time or exposure limit to bisphosphonate use and whether a drug holiday from them is warranted.
DR. GALL: Dr. McClung, could you please describe how you monitor a patient after initiation of bisphosphonate therapy and then discuss an atypical fracture?
DR. MCCLUNG: Treatment with any osteoporosis drug is generally monitored by measuring BMD 2 years after the patient has started therapy. The changes in BMD with treatment are quite modest, so we expect to see either a modest increase or at least stability. If a clear decrease in BMD is observed, we consider noncompliance, secondary causes of bone loss, and other reasons for treatment failure.
In theory, biochemical testing of bone turnover should be useful in monitoring therapy. However, because of limitations in the quality and the reproducibility of the assays in the clinical setting, it is difficult to use the results. I think that marker measurement is not ready for use in the everyday clinic, although it has been very valuable in our research.
Atypical fracture is important. As mentioned earlier, there has been concern right from the time when bisphosphonate research began about the potential for skeletal consequences with long-term therapy because of the pharmacology of bisphosphonates. We know that these drugs accumulate in the skeleton over time, and there were concerns about whether we would see progressive inhibition of bone turnover with long-term therapy. Although we were pleased to observe persistent, but not progressive, reduction in bone turnover with long-term treatment, at least for up to 10 years,11 it appears that some individuals, or perhaps, a unique subset of patients, experience too much inhibition of bone metabolism for prolonged durations. When this happens, bone brittleness occurs and is manifested by atypical chalk stick-like fractures of the femur. It is clear that there is a duration-dependent increase in risk, with fractures occurring in roughly 1 in 1 000 patients who have completed at least 10 years of alendronate therapy.12 If we properly decide whom to treat and how to treat, it is important to recognize that this risk is much, much lower than the risk of important fracture, such as that of the hip and spine, in patients who are not treated with bisphosphonate therapy.13 We should reserve bisphosphonates for patients who clearly have osteoporosis or are at high risk for fracture.
DR. GALL: Dr. Maricic, can you conclude on the use of calcitonin, denosumab, and teriparatide, ie, some of the other drugs approved for the treatment of osteoporosis?
DR. MARICIC: Calcitonin is extremely safe but it isn’t very effective and has been shown to reduce spinal fracture risk by 33% and have no effect on hip fracture risk,14 so I personally haven’t prescribed it in almost 10 years.
Denosumab, a receptor activator of nuclear factor-kB (RANK)-ligand inhibitor and monoclonal antibody, is probably among the most effective medications we have. Because it bypasses the GI tract, it’s an excellent choice for patients who develop GI problems with bisphosphonates. Nevertheless, because it is a very potent osteoclast inhibitor, it must be used carefully in patients prone to hypocalcemia, with renal failure, or who are extremely vitamin D deficient. Although hypocalcemia must be considered before initiating its use, I think it is an extremely effective agent.
Teriparatide is the only anabolic agent currently approved for use in patients at high risk of fracture, and that’s for whom we mainly use it. Because its mode of action is completely different from that of bisphosphonates, we use it for patients with either very low bone density or with multiple fractures who have not responded to bisphosphonate therapy. The Food and Drug Administration (FDA) has approved teriparatide therapy for only 2 years, after which it must be followed by antiresorptive therapy. Unfortunately, I occasionally see patients who had not been given antiresorptives after 2 years of teriparatide, causing them to lose any benefit they may have derived from being on this very expensive drug for 2 years. It must always be followed up by an antiresorptive drug.
DR. MCCLUNG: Regarding a drug holiday, you can consider it if you observe a duration-dependent increase in the risk of atypical fracture.15,16 The FDA has provided us with at least a general template for when it should be considered.17 Based on the limited information we have, it is suggested that fracture risk be reassessed after 3 to 5 years of therapy. For patients with a modest risk for fracture at that point, ie, they no longer have osteoporosis according to the results of bone density testing, it is suggested that therapy be discontinued for 1 to 2 years.
For patients found to remain at high risk for fracture, especially spine fracture, continuation of therapy is recommended. The evidence for this recommendation came from 2 large extension studies of the alendronate and zoledronic acid clinical trials.18,19
If treatment is discontinued, the question of when, if ever, to restart therapy arises. The data from the clinical trials suggest that neither the measurement of bone density nor bone markers are helpful in that regard. So, in my clinic, we treat the holiday like a vacation that has a finite end.13 We take patients off alendronate for 2 or 3 years but off risedronate for only 1 year because its effects wear off more quickly. At that point, we reassess the patient. If he/she meets the criteria for treatment with an osteoporosis drug again, we decide on the best treatment option.
DR. GALL: Dr. Lisse, please describe how treating steroid-induced male osteoporosis differs from treating postmenopausal and female osteoporosis.
DR. LISSE: Before I do so, I wanted to add that a flu-like syndrome sometimes occurs with bisphosphonate use. In a corollary to what Dr. McClung just discussed, the European registries provide at least some reassuring evidence that when patients stop taking bisphosphonates, the risk of atypical fracture appears to decrease fairly rapidly, whereas bisphosphonate efficacy doesn’t seem to tail off as quickly.15 It should be reassuring that if patients stop taking a drug, they may have some protection during that period in terms of osteoporosis coverage, unlike when they stop taking estrogen or teriparatide, whose effects tail off rather rapidly.
With glucocorticoid-induced osteoporosis, the biggest issue is probably the fact that fractures tend to occur early and at a higher bone density than what we’re used to seeing with traditional postmenopausal osteoporosis. So it has thrown the old paradigm into disarray. Before the introduction of FRAX, treatment was recommended for patients with a T-score of −1. As the FRAX includes glucocorticoids as a risk factor, its use is very helpful in this regard.
FRAX does have its limitations, and there are physicians who are concerned that it does not include consideration of steroid duration or dose. I think the American College of Rheumatology’s recommendation is to measure bone density and then subdivide the patient population into low risk, moderate risk, and high risk according to the risk for major osteoporotic fracture of ≤10%, 10% to 20%, and ≥20%, respectively.20 Treatment should be considered based on the risk and dosage. Patients taking a dose of 7.5 mg or higher probably need treatment, even if they’re at low risk. Patients on lower doses probably need treatment if they remain on glucocorticoid therapy for more than 3 months.
Although most fractures due to steroid use are of the spine, not all are. I’m sure all of us on the panel are old enough to remember the old asthmatics who used to take large doses of steroids. Certainly, one of the easiest things to do is to taper patients off steroids or reduce the dose down to the lowest possible dose. The use of topical steroids is preferred to that of oral steroids or inhaled steroids.
The NOF guidelines for testing for male osteoporosis differ from those for testing female osteoporosis. Although they recommend that all women older than 65 years be tested, they do not recommend routine testing in men older than 70 years. I think that this latter recommendation, which is based on a US Preventative Health Service Task Force recommendation,21 is probably a mistake and rather confusing.
Even though there has been a study of raloxifene in men, the guidelines are more limited regarding how men who are hypogonadal should be treated. Testosterone should be measured in all men, and those found to be hypogonadal deserve testosterone replacement. Again, the backbone of therapy is the use of bisphosphonates for the most part. Teriparatide has also been approved for use in men, although it has not been proven to provide protection against hip fracture.
DR. GALL: We’ve had an extensive discussion today on low bone density diseases, focusing mostly on osteoporosis. We have discussed at some length the risk factors and the diagnostic tools that we have, particularly the DEXA scan and FRAX, to assess the risk of fracture. We then discussed the risk factors, including comorbidities; means of prevention; and the different treatment modalities, including physical therapy and several nonpharmacologic therapies, in addition to the various medical therapies, including hormone replacement, bisphosphonates, calcitonin, denosumab, and teriparatide. We’ve also briefly touched on the differences between postmenopausal osteoporosis and steroid-induced osteoporosis and male osteoporosis.

Dr. Maricic, what are the different types of osteopenia that primary care clinicians encounter in their practice?
DR. MARICIC: Osteopenia has several connotations, depending on the setting in which it is diagnosed. Radiologists will describe a patient as being osteopenic based on the subjective assessment that the patient has low bone density on radiography. With particular reference to osteoporosis or bone densitometry, osteopenia refers to a dual-energy X-ray absorptiometry (DEXA) T-score, which is a comparison of the bone mass of a patient to that of a young, ideal patient of the same sex and ethnicity.
DR. GALL: Is osteoporosis the only disease or are there other diseases that we may see associated with osteopenia?
DR. MARICIC: Neither osteopenia nor osteoporosis diagnosed by the DEXA score is necessarily caused by estrogen deficiency. The DEXA report tells you whether a patient has low bone density but not about the etiology. Although estrogen deficiency is a common cause of osteopenia or osteoporosis, other conditions such as primary hyperparathyroidism, multiple myeloma, vitamin D deficiency, osteomalacia and the conditions associated with it, chronic renal failure with osteitis, fibrosis cystica, and hyperparathyroidism should be considered by the primary care physician.
It’s typically recommended that all patients with low bone density diagnosed by their DEXA score have a chemistry screening done to determine the calcium and alkaline phosphatase levels, as well as 25-hydroxy-vitamin D level, in order to ensure that the patient is not vitamin D deficient. A 24-hour urine test is also recommended to ensure that the vitamin D level is not low, suggesting malabsorption, such as what we see in vitamin D deficiency or celiac disease, or that it’s not high, suggesting idiopathic hypercalciuria.
Those are the main, most common disorders that we’d like to exclude in patients with osteopenia or especially osteoporosis. We would also want to exclude secondary hyperparathyroidism; vitamin D deficiency; and, when suspected, celiac disease, idiopathic hypercalciuria, and multiple myeloma. Those are some of the conditions to be considered, especially when the T-score does not accord with the clinical history.
DR. GALL: Dr. McClung, can you please discuss the use of X-ray and DEXA scan as diagnostic tools?
DR. MCCLUNG: These 2 tools have completely different roles. We use the DEXA scan to measure bone density, primarily in the hip and the spine, in postmenopausal women and older men to obtain a T-score that is, a value comparing the patient’s bone density to the average bone density value of young adults of the same sex. A T-score of −2.5 is thought to be consistent with osteoporosis in postmenopausal women and older men, but, as Dr. Maricic pointed out, a T-score of −2.5 only tells us that the patient has low bone density. Before we conclude that the patient has osteoporosis, all of the other causes of low bone density, including osteomalacia, osteogenesis imperfecta, and any of the secondary causes that were outlined, need to be excluded.
I believe that osteopenia, which is defined as a T-score value between −1 and −2.5, is not a very useful diagnostic term for clinical purposes. We know that low bone density is one of several risk factors for fracture. Within the group of patients with osteopenia are those who are at very high risk for fracture, including older people and those who have had fractures, as well as many patients who are not at high risk for fracture. In response to this problem, the World Health Organization developed the Fracture Risk Assessment Tool (FRAX), a fracture risk assessment tool used to help distinguish patients with high or low fracture risk.1
DR. GALL: Clinicians often find the terms used in the DEXA report confusing. Could you define absolute bone mineral density (BMD) and Z-score for the clinician?
DR. MCCLUNG: The BMD test measures the bone mineral content of a specific anatomic region and the area of that region and divides those 2 numbers to get an estimate of the BMD. It is not a true bone density test, but rather a measurement of calcium content within a region of bone.
The BMD value is translated into a T-score by comparing it to the average value for healthy young adults of the same sex and is then used for diagnosis in postmenopausal women. The Z-score is obtained by comparing the patient’s BMD value with the expected average value for healthy adults of the same age and sex and is used to determine whether a low BMD value for that patient is unexpected. A low T-score for a 55-year-old woman may be surprising, whereas a low T-score for a 90-year-old woman would be expected. A Z-score lets us know how concerned we should be.
DR. GALL: Dr. Lisse, you read a lot of DEXA scans. What can give a false value? Can you tell us about that and discuss the FRAX?
DR. LISSE: Dr. McClung wrote a very nice treatise on the FRAX,2 a tool that assesses the risk of fracture in bisphosphonate-naïve patients based on the consideration of risk factors, in addition to the BMD value. The DEXA measures bone quantity, but does not assess the risk factors for osteoporosis, of which I think prior fracture and patient age are the most important.
By considering the risk factors of smoking history, advanced age, prior fracture, and family history of fracture, and by adjusting for the country and racial origin of the patient, the FRAX provides a better measure of fracture risk for the osteopenic patient compared to BMD alone. It also provides a value, the 10-year fracture risk, that’s easier for the primary doctor to interpret compared to T-scores and Z-scores, which require comparison in terms of standard deviations.
DR. GALL: How can we use the FRAX if we are interested in doing so?
DR. LISSE: The tool is available online and very easy to use. Usually, you complete the assay using the BMD value. You can actually perform the assay without a BMD value, but I think that including the BMD value improves the precision and predictive value of the results. You just plug in the information online and are given a reading. Recent literature suggests that you can use it for patients who are taking bisphosphonates, but I think that’s a little bit further down the line in our discussion.
DR. GALL: A FRAX result states that a patient has a 10-year risk of major fracture of 8%. How do I use that result? Should I start treating the patient?
DR. LISSE: Several studies that examined local socioeconomic factors concluded that using a 20% risk of major osteoporotic fracture and a 3% risk of hip fracture are cost-effective thresholds for the diagnosis of patients in the United States. Although they should not be considered absolute, they are the current thresholds, and I think physicians can use them as criteria to make treatment decisions.
DR. MCCLUNG: That description is correct. FRAX has a scientific base and is a very highly validated tool that accurately predicts fracture probability in healthy middle-aged and older adults.1 Using the tool is a good first step while considering whether osteoporosis treatment is justified. The threshold values of a 10-year probability of hip fracture of 3% and a 10-year probability of major osteoporotic fracture of 20% are specific to the United States, which is based on the United States healthcare policy and where osteoporosis fits into the United States medical priorities. Other countries have their own thresholds that are very different.
DR. GALL: Dr. Maricic, we’ve talked about the DEXA and the FRAX. What other imaging tools are available and what are their roles?
DR. LISSE: The other issue is that the FRAX uses femoral neck density, which is a good predictor; however, in some patients, especially patients taking glucocorticoids, the spine density may be lower than the hip density. A low spine T-score should also be taken into account. We must individualize patients and not become overly focused on any one tool, although the use of the FRAX is certainly a major step forward from the use of only the T-score, for which, former guidelines recommended treatment for patients with scores within the wide range of −1 and −2.5.
DR. GALL: Another issue regarding DEXA is that we often get a false high BMD in patients with fracture of the lumbar spine, osteoarthritis, or issues with alignment of the spine. In such cases, it is important to examine the image, as the presence of bone abnormalities may render the spine DEXA score and the spine T-score less important.
DR. MARICIC: The role of other modalities in diagnosing osteoporosis in the United States is limited because of the widespread availability of DEXA in most communities. A few communities in Arizona have access to only quantitative computed tomography, which, although tends to overdiagnosise osteoporosis, can be helpful if bone density is found to be low and the clinical setting is appropriate.
Likewise, quantitative ultrasound in patients older than 65 years has a very valid role in estimating risk of fracture, but because DEXA is so widely available, we do not or usually should not use ultrasound instead of a DEXA scan and ultrasound cannot be used to monitor or follow-up patients with treatment. The only modality that should be used is the DEXA scan because of its very high precision.
DR. GALL: I have seen the use of ultrasound in both remote areas and nursing homes and other areas where it is difficult for patients to visit an office at which a DEXA scan performed, but it is not as accurate as the DEXA scan.
DR. MCCLUNG: Yes, but my understanding is that you use the ultrasound to determine whether you need a DEXA scan.
DR. MARICIC: Yes, but you shouldn’t use the ultrasound to start therapy or monitor therapy.
DR. MCCLUNG: FRAX, which can be calculated without a bone density test, provides a much more accurate assessment.
DR. MARICIC: And FRAX is probably cheaper and easier.
DR. GALL: Dr. McClung, would you talk a little bit about bone markers? I once heard you speak about their role in making a decision about when to treat patients with borderline DEXA and FRAX values.
DR. MCCLUNG: Bone markers are values obtained from blood and urine tests that reflect the activity of the bone cells. Generally, high levels of bone markers reflecting high levels of bone absorption are predictive of more rapid rates of bone loss. So, when a physician is deciding whether to treat, measuring a bone marker can sometimes provide important information to help make the decision. A bone turnover rate in the low–normal range in a bisphosphonate-naïve patient indicates that his/her bone density is stable and that he/she may benefit less from treatment compared to a patient with a high rate.
You can also use bone marker values to determine whether treatment has been effective, particularly if you use antiresorptive agents such as bisphosphonates. Patients with celiac disease or those who have had a gastrectomy may not absorb oral bisphosphonates, so their markers may remain high even if they are under treatment. Although there are certain patients for whom bone markers are helpful, the use of these markers is not routine in the management of most patients with osteoporosis.
DR. GALL: I would say that bone markers are generally overused. Another area in which the use of bone marker values may be helpful is compliance. I’ve used bone biomarker values in cases in which, for example, I start a patient on a weekly bisphosphonate and the patient comes back 12 weeks later saying that he/she doesn’t need a prescription. In such cases, I may perform bone marker testing to see whether the patient has been compliant.
Is there ever a time when we need to do a bone biopsy?
DR. MARICIC: I think a bone biopsy is only helpful for patients with long-term renal failure and dialysis to separate out the various forms of renal osteodystrophy. Although we used to perform a biopsy to help us understand bone turnover or detect osteomalacia, we can now do both with a biochemical test.
In some cases, we want to perform a bone marrow biopsy to look for marrow-based diseases such as mastocytosis or myeloma.
DR. GALL: I’d now like to discuss the prevention of osteoporosis and the risk factors that indicate testing and treatment of patients who are not postmenopausal.
DR. LISSE: There are risk factors that are nonmodifiable, including family history and genetics; modifiable risk factors, including level of exercise, especially weight-bearing exercise, which can be decreased; smoking, which can be discontinued or at least attenuated; and alcohol intake, which can be decreased. I think the role of caffeine is still controversial, although I’d love to hear from the other members of the panel about that.
I think we have overemphasized the importance of calcium and vitamin D supplementation. However, I measure the serum 25-hydroxy-vitamin D level, which according to me, is becoming more and more popular, and I try to keep it at around 30 ng/mL. I think all female patients should obtain some calcium supplementation, especially if their dietary intake is not adequate.
It was surprising to know that there’s probably a higher prevalence of vitamin D insufficiency in Arizona than in Minnesota in spite of the abundance of sunshine in the former.
DR. GALL: I consider patients who are thin, have poor bone stock, are malnourished, did not drink milk in their childhood, and have a family history of hip fracture in a close relative to be at higher risk, and I tend to test them early and consider either preventative treatment or just treatment for them.
I think an appropriate target for daily intake of calcium is between 800 and 1 200 mg, including that obtained from diet. The appropriate target for vitamin D intake in the absence of regular sun exposure is between 600 and 2 000 units per day.
DR. LISSE: Most recommendations that I’ve seen for calcium are about 800 mg, but they vary widely.
DR. MCCLUNG: Let’s get back to the management of premenopausal women with risk factors for low bone mass such as small body size, family history of osteoporosis, and medical problems that may lead to impaired bone health such as amenorrhea during early adolescence. For these women, maintaining adequate nutrition and physical activity and avoiding harmful lifestyle factors should be encouraged, but bone density testing is rarely necessary. If premenopausal women are estrogen replete, even if they have low bone density, treatment with osteoporosis drugs is not recommended. Individuals with risk factors for low bone density should be screened at the time of menopause to decide whether aggressive prevention of the rapid bone loss that occurs at that particularly important time is warranted.
DR. GALL: Dr. Maricic, there are 2 topics I’d like you to discuss. The first is comorbidities, specifically conditions such as thyroid disease, that we need to pay attention to, and the second is hormone replacement therapy and its current role.
DR. MARICIC: The NOF guidelines for the diagnosis and treatment of osteoporosis5 list a number of comorbid disorders and medications that may be responsible for a patient’s low bone density. We should consider the potential for osteoporosis in all men and women over the age of 50 years, especially if they have other disorders or medications known to affect bone mineral metabolism.
The NOF guidelines list about 30 diseases implicated in low bone density, including type 2 diabetes, hemochromatosis, and androgen- and estrogen-deficiency hypogonadism. Low bone density should be considered in patients with gastrointestinal (GI) disorders, of which celiac disease is the most important and common; those who have undergone GI bypass or other types of GI surgery; and those with hematological disorders such as mastocytosis and myeloma. Because chronic inflammatory production of cytokines and calcium immobilization lead to accelerated bone loss, low bone density should be considered in patients with rheumatic disorders, including systemic lupus; ankylosing spondylitis; and especially, rheumatoid arthritis, which FRAX identifies as a major risk factor for accelerated bone loss. Finally, low bone density should be considered in patients with a number of miscellaneous conditions, including chronic obstructive pulmonary disease, emphysema, chronic asthma, and sarcoidosis.
Regarding medications, the agents most commonly associated with low bone density are glucocorticoids. Low bone density should also be considered in patients taking certain anticonvulsants, especially phenobarbital and phenytoin, which can lead to accelerated degradation of 25-hydroxy-vitamin D and very low vitamin D levels and consequent osteomalacia, and in those taking aromatase inhibitors, which are now very important in the treatment of breast cancer.
DR. GALL: I’d just like to mention again the association between low bone density and both thyroid disease and overmedication in thyroid replacement therapy.
DR. MCCLUNG: We should probably also include proton pump inhibitors and selective serotonin reuptake inhibitors, which have been correlated with increased rates of fracture, although the mechanism underlying that correlation is unclear.
DR. LISSE: Do you mean that their wide use poses a concern?
DR. MCCLUNG: Yes, but their effect does not seem to be reflected in bone density testing. So, while recognizing their use as an independent risk factor for fracture is important, it is still unclear whether it should be considered while deciding whether to treat with an osteoporosis drug.
DR. MARICIC: Regarding hormone replacement therapy, we must first distinguish between hormone replacement, which is a combination of estrogen and progesterone for women with an intact uterus, and estrogen replacement or estrogen therapy, which is estrogen alone for women who have undergone a hysterectomy. Definitely, there are differences in the potential for adverse effects between these 2 groups.
I believe the data from the Women’s Health Initiative (WHI) suggested that increased risk of thrombosis and breast cancer is more commonly seen with hormone therapy and may be due more to progesterone than to estrogen replacement.6 There are also some differences in the risk with regard to the age of starting hormone therapy in our patients.
From the WHI, we know that hormone therapy prevents bone loss and reduces the risk of hip and other fractures. I think hormone therapy, especially estrogen therapy for women with an intact uterus, is an option to protect the skeleton in women with low bone density, especially those who are perimenopausal or early postmenopausal.
I personally avoid starting hormone therapy in patients above the age of 70 years and sometimes even above 65 years, but I believe it can be an option for women between the ages of 50 and 60 years with low bone density and no contraindications. For women with a strong family history of breast cancer, I usually recommend raloxifene. We’re now trying to limit the lifetime exposure of women to bisphosphonates, so I tend to reserve them for older women at very high risk of fracture, and almost never administer them to women aged 50 to 60 years.
I think that hormone therapy is the first option for women between 50 and 60 years with no strong family history of breast cancer. If there is, I start them on Evista, when possible.
DR. LISSE: I think that bisphosphonate therapy has been the primary choice of osteoporosis therapy since at least 2 000, which is when alendronate came into the market under its brand name. These drugs have been shown to reliably decrease fracture and improve the quality of life. Some drugs, particularly zoledronic acid, actually decrease mortality in patients with hip fracture.7
There are some differences among them. The first one on the market obviously was alendronate, so there’s probably the most data on it. Risedronate, alendronate, zoledronic acid, denosumab, and teriparatide have been shown to reduce vertebral and nonvertebral fracture; ibandronate, to reduce spinal but not nonvertebral fracture; alendronate, risedronate, denosumab, and zoledronic acid, to prevent hip fracture in postmenopausal women; and risedronate, to decrease vertebral and nonvertebral fracture in men.7
The original studies on the effect of many of these drugs on fracture risk were conducted with daily dosing, and equivalent dosing in weekly and monthly regimens has been used and approved, sometimes without fracture data. The drugs work, their safety-to-risk ratio is quite good, and we have long-term experience with them. I think it’s not surprising that a small percentage of patients who have been on them for a decade or more have issues and side effects. There are risks to taking these drugs, as there are with any other drug.
Probably, the most common risk is GI complications, ranging from irritation to esophageal perforation, which surfaced shortly after alendronate came on the market. To prevent GI complications, strict regimens have been developed for oral bisphosphonate use. To some extent, I think that they limit our patient population because many cannot or will not comply with the requirement of taking the drug first thing in the morning on an empty stomach with approximately 230 mL of water and remain upright for 30 to 60 minutes, depending on the medication, to realize any benefit.
Gastrointestinal complications, including those affecting the esophagus, are, by far, the most common issues observed with bisphosphonate therapy. Gastric ulcerations in certain patients, especially in those who use risedronate in coated form, have also been observed.
There are other probably less common but controversial issues, including a possible association with atrial fibrillation, which was identified in the Health Outcomes and Reduced Incidence with Zoledronic Acid Once Yearly (HORIZON) study.8 An association with alendronate was also suspected, but a recent meta-analysis does not support this association.9
An association with esophageal cancer has been anecdotally described in several populations, but I think that the data are mixed at this point. Then, there is the association with osteonecrosis of the jaw and atypical fracture, both of which are quite rare and occur in between 1 in 10 000 to 1 in 100 000 patients.10 I think that the wide coverage of this association in the lay press may have caused many patients who probably shouldn’t have gone off bisphosphonates, to go off them.
A positive byproduct of these associations being reported could be increased research into whether there should be a time or exposure limit to bisphosphonate use and whether a drug holiday from them is warranted.
DR. GALL: Dr. McClung, could you please describe how you monitor a patient after initiation of bisphosphonate therapy and then discuss an atypical fracture?
DR. MCCLUNG: Treatment with any osteoporosis drug is generally monitored by measuring BMD 2 years after the patient has started therapy. The changes in BMD with treatment are quite modest, so we expect to see either a modest increase or at least stability. If a clear decrease in BMD is observed, we consider noncompliance, secondary causes of bone loss, and other reasons for treatment failure.
In theory, biochemical testing of bone turnover should be useful in monitoring therapy. However, because of limitations in the quality and the reproducibility of the assays in the clinical setting, it is difficult to use the results. I think that marker measurement is not ready for use in the everyday clinic, although it has been very valuable in our research.
Atypical fracture is important. As mentioned earlier, there has been concern right from the time when bisphosphonate research began about the potential for skeletal consequences with long-term therapy because of the pharmacology of bisphosphonates. We know that these drugs accumulate in the skeleton over time, and there were concerns about whether we would see progressive inhibition of bone turnover with long-term therapy. Although we were pleased to observe persistent, but not progressive, reduction in bone turnover with long-term treatment, at least for up to 10 years,11 it appears that some individuals, or perhaps, a unique subset of patients, experience too much inhibition of bone metabolism for prolonged durations. When this happens, bone brittleness occurs and is manifested by atypical chalk stick-like fractures of the femur. It is clear that there is a duration-dependent increase in risk, with fractures occurring in roughly 1 in 1 000 patients who have completed at least 10 years of alendronate therapy.12 If we properly decide whom to treat and how to treat, it is important to recognize that this risk is much, much lower than the risk of important fracture, such as that of the hip and spine, in patients who are not treated with bisphosphonate therapy.13 We should reserve bisphosphonates for patients who clearly have osteoporosis or are at high risk for fracture.
DR. GALL: Dr. Maricic, can you conclude on the use of calcitonin, denosumab, and teriparatide, ie, some of the other drugs approved for the treatment of osteoporosis?
DR. MARICIC: Calcitonin is extremely safe but it isn’t very effective and has been shown to reduce spinal fracture risk by 33% and have no effect on hip fracture risk,14 so I personally haven’t prescribed it in almost 10 years.
Denosumab, a receptor activator of nuclear factor-kB (RANK)-ligand inhibitor and monoclonal antibody, is probably among the most effective medications we have. Because it bypasses the GI tract, it’s an excellent choice for patients who develop GI problems with bisphosphonates. Nevertheless, because it is a very potent osteoclast inhibitor, it must be used carefully in patients prone to hypocalcemia, with renal failure, or who are extremely vitamin D deficient. Although hypocalcemia must be considered before initiating its use, I think it is an extremely effective agent.
Teriparatide is the only anabolic agent currently approved for use in patients at high risk of fracture, and that’s for whom we mainly use it. Because its mode of action is completely different from that of bisphosphonates, we use it for patients with either very low bone density or with multiple fractures who have not responded to bisphosphonate therapy. The Food and Drug Administration (FDA) has approved teriparatide therapy for only 2 years, after which it must be followed by antiresorptive therapy. Unfortunately, I occasionally see patients who had not been given antiresorptives after 2 years of teriparatide, causing them to lose any benefit they may have derived from being on this very expensive drug for 2 years. It must always be followed up by an antiresorptive drug.
DR. MCCLUNG: Regarding a drug holiday, you can consider it if you observe a duration-dependent increase in the risk of atypical fracture.15,16 The FDA has provided us with at least a general template for when it should be considered.17 Based on the limited information we have, it is suggested that fracture risk be reassessed after 3 to 5 years of therapy. For patients with a modest risk for fracture at that point, ie, they no longer have osteoporosis according to the results of bone density testing, it is suggested that therapy be discontinued for 1 to 2 years.
For patients found to remain at high risk for fracture, especially spine fracture, continuation of therapy is recommended. The evidence for this recommendation came from 2 large extension studies of the alendronate and zoledronic acid clinical trials.18,19
If treatment is discontinued, the question of when, if ever, to restart therapy arises. The data from the clinical trials suggest that neither the measurement of bone density nor bone markers are helpful in that regard. So, in my clinic, we treat the holiday like a vacation that has a finite end.13 We take patients off alendronate for 2 or 3 years but off risedronate for only 1 year because its effects wear off more quickly. At that point, we reassess the patient. If he/she meets the criteria for treatment with an osteoporosis drug again, we decide on the best treatment option.
DR. GALL: Dr. Lisse, please describe how treating steroid-induced male osteoporosis differs from treating postmenopausal and female osteoporosis.
DR. LISSE: Before I do so, I wanted to add that a flu-like syndrome sometimes occurs with bisphosphonate use. In a corollary to what Dr. McClung just discussed, the European registries provide at least some reassuring evidence that when patients stop taking bisphosphonates, the risk of atypical fracture appears to decrease fairly rapidly, whereas bisphosphonate efficacy doesn’t seem to tail off as quickly.15 It should be reassuring that if patients stop taking a drug, they may have some protection during that period in terms of osteoporosis coverage, unlike when they stop taking estrogen or teriparatide, whose effects tail off rather rapidly.
With glucocorticoid-induced osteoporosis, the biggest issue is probably the fact that fractures tend to occur early and at a higher bone density than what we’re used to seeing with traditional postmenopausal osteoporosis. So it has thrown the old paradigm into disarray. Before the introduction of FRAX, treatment was recommended for patients with a T-score of −1. As the FRAX includes glucocorticoids as a risk factor, its use is very helpful in this regard.
FRAX does have its limitations, and there are physicians who are concerned that it does not include consideration of steroid duration or dose. I think the American College of Rheumatology’s recommendation is to measure bone density and then subdivide the patient population into low risk, moderate risk, and high risk according to the risk for major osteoporotic fracture of ≤10%, 10% to 20%, and ≥20%, respectively.20 Treatment should be considered based on the risk and dosage. Patients taking a dose of 7.5 mg or higher probably need treatment, even if they’re at low risk. Patients on lower doses probably need treatment if they remain on glucocorticoid therapy for more than 3 months.
Although most fractures due to steroid use are of the spine, not all are. I’m sure all of us on the panel are old enough to remember the old asthmatics who used to take large doses of steroids. Certainly, one of the easiest things to do is to taper patients off steroids or reduce the dose down to the lowest possible dose. The use of topical steroids is preferred to that of oral steroids or inhaled steroids.
The NOF guidelines for testing for male osteoporosis differ from those for testing female osteoporosis. Although they recommend that all women older than 65 years be tested, they do not recommend routine testing in men older than 70 years. I think that this latter recommendation, which is based on a US Preventative Health Service Task Force recommendation,21 is probably a mistake and rather confusing.
Even though there has been a study of raloxifene in men, the guidelines are more limited regarding how men who are hypogonadal should be treated. Testosterone should be measured in all men, and those found to be hypogonadal deserve testosterone replacement. Again, the backbone of therapy is the use of bisphosphonates for the most part. Teriparatide has also been approved for use in men, although it has not been proven to provide protection against hip fracture.
DR. GALL: We’ve had an extensive discussion today on low bone density diseases, focusing mostly on osteoporosis. We have discussed at some length the risk factors and the diagnostic tools that we have, particularly the DEXA scan and FRAX, to assess the risk of fracture. We then discussed the risk factors, including comorbidities; means of prevention; and the different treatment modalities, including physical therapy and several nonpharmacologic therapies, in addition to the various medical therapies, including hormone replacement, bisphosphonates, calcitonin, denosumab, and teriparatide. We’ve also briefly touched on the differences between postmenopausal osteoporosis and steroid-induced osteoporosis and male osteoporosis.

The Medical Roundtable: Osteoarthritis Coping Guidelines for the Elderly
DR. BLOCK: Throughout the 20th century, we always considered OA to be primarily a degenerative disease of cartilage, but during the past decade or more, 2 things have become apparent: First, from a clinical perspective, OA is not just a structural degenerative process, it is primarily a very painful disease with pain being its most prominent feature. Second, the degenerative process involves not only the cartilage but the entire joint and all the involved structures within it.
A reasonable working definition of OA right now would be a painful degenerative process involving all the joint structures and is not primarily inflammatory but involves progressive deterioration of joint structures including articular cartilage. It’s important to keep in mind that pain itself is critical because as individuals age, everybody has some degenerative processes in their joints, and if we look hard enough, we can find the pathological features of OA in all elderly people. However, not all elderly people actually have the clinical disease.
DR. GALL: In a moment, we’ll talk about the causes of this, but, Dr. Moskowitz, would you tell us what the burden of this disease is here in the United States and worldwide?
DR. MOSKOWITZ: Well, it’s the most common form of arthritis and affects nearly 27 million or more Americans.1 It’s the most common disabling disease of the rheumatologic group, and it’s very disabling among all diseases.
DR. GALL: In the United States, you say that there’s about—
DR. MOSKOWITZ: About 27 million people with OA. And, in a decade, it is anticipated that the number will significantly increase.
DR. GALL: How many of those people are affected to the point that they’re unable to do their normal activities of daily living (ADLs)?
DR. MOSKOWITZ: Well, in terms of disability, about 80% of patients with OA have some degree of movement limitation, 25% cannot perform major ADLs, 11% of adults with knee OA need help with personal care, and 14% require help with routine needs.2
DR. GALL: Dr. Block, you talked about pain as a major manifestation of this disease. Does everybody who has OA present with pain?
DR. BLOCK: Again, it’s a definitional question; there is a distinction between clinically evident OA and asymptomatic structural degeneration of the joint. The population that Dr. Moskowitz was just describing, which comprises 20 to 30 million people, has doctor-diagnosed symptomatic OA, which is a painful disease. A much higher number of people who have structural degenerative disease would be diagnosed by radiography and said to fulfill a radiographic definition of OA, but all of the people who Dr. Moskowitz refer to have pain.
DR. MOSKOWITZ: Pain is what brings a patient to the doctor. I’ll often ask my patients, “How are you doing and what can I do for you?” They have limited motion and can’t get around. They say, “Dr. Moskowitz, I just want to get rid of the pain. I’ll worry about the swelling and getting around later.” And, that’s what really motivates them to get medical attention.
DR. GALL: Often, we will get consultations from primary care physicians for a patient who has OA that’s been picked up by radiography, and the patients will come and really not complain of pain in that area or possibly might have another underlying disease that’s causing the pain that’s not related to the OA. Dr. Block, do you want to say a word about that?
DR. BLOCK: Sure. By the age of 80 years, essentially, 100% of the population will have evidence of radiographic OA in at least one of their large joints. If you start with that number and you’re then referred an elderly patient merely for the radiographic appearance of OA, that doesn’t tell you very much about what’s going on clinically, and so, most of us would not even describe that as a clinical disease.
They may have a degenerative process in their knee, hip, etc, but of that group, say at the age of 80 years where almost 100% of people will have radiographic evidence of OA, only about 15% to 20% have symptomatic disease.3 That’s the culprit that I think we’re talking about clinically—people who not only have degenerative structural disease but also have symptoms that are interfering with their quality of life or their daily activities.
DR. MOSKOWITZ: I think that’s an important point, Dr. Block. For example, we all see patients who come in complaining of hip pain and you examine their knees as well and they have terrible genu varum (bowleg) and you say, “Do your knees bother you?” and they say, “Doctor, my knees are fine.” You think, my goodness, how can you walk? It isn’t necessarily true that if you have a deformity or involvement of a joint that you’re going to have pain, but if you have painful joints, that brings you to the doctor.
DR. GALL: Dr. Block, once again, I would like you to summarize the etiology of OA. Obviously, there has been much research and much information that has come to light in recent years regarding the causes of this disease.
DR. BLOCK: As I said, throughout the 20th century, people interested in the pathophysiology of OA were quite convinced that it was a degenerative process of the articular cartilage. As people age, the articular cartilage starts degenerating, and when there is absence of intact cartilage that ought to be providing essentially frictionless articulation of the bones during motion, there is deterioration, and that’s what we always considered to be OA.
Of course, the missing link in that paradigm is that cartilage itself has no nerve or blood supply and is therefore painless, and yet, people have horrible pain with this disease. So, our understanding over the past 10 or 15 years has really dramatically progressed, and we have begun to appreciate both degenerative and reactive processes in the subchondral bone, the ligaments, and the muscle.
The way we look at the pathophysiology of the onset and progression of the disease today is that there is primarily a degenerative process that stimulates reactive processes throughout the joint and even in the immune and inflammatory pathways. So, the reaction to that degenerative process sometimes causes stimulation of nociceptors and a lot of pain because of either local inflammation or mechanical alterations.
The degeneration itself, as I said, is painless. Often, people can have very degenerative joints, as Dr. Moskowitz just mentioned, and have no pain and therefore no clinical symptoms, so the disease is a combination of the degeneration and the secondary stimulated pain.
DR. GALL: So, is this primarily a biochemical or a cellular disease? Is it a genetic disease?
DR. BLOCK: Yes to all.
DR. MOSKOWITZ: There are a number of factors, Dr. Gall, involved in this condition. First, for example, is aging. We see that the frequency of OA increases logarithmically as we age, and there are pathologic changes with age that appear to lead to OA. For example, pigmented collections in the joint, comprising advanced glycation end products, occur that may predispose a patient to OA. You’re going to find more OA in an aging population.
The second factor is trauma. Professional football and basketball players, for example, who have chronic trauma, meniscal injuries, or cruciate ligament injuries are predisposed to OA. Third—the big risk factor, of course—is being overweight or obese. Patients who are overweight have a much higher frequency of OA, particularly in the knees. Last, there are genetic factors. For example, OA in the hands, which is more often seen in women, is genetically oriented so that if your mother had it or your aunt had it, you’re more likely to get it. Accordingly, there are multifactorial etiological factors that we have to try to address.
DR. GALL: Can you say a word about the different areas of the body that are associated with OA and talk a little bit about the difference between OA of the hands that we see frequently in women in relation to OA of the knee, hips, and spine, which can be devastating for individuals?
DR. MOSKOWITZ: Any joint can have it. It can be in the ankle, for example, if there has been trauma, but we’re looking particularly at the knees, the hips, the hands, and the spine. It’s interesting—certain joints in the hands are predisposed to OA including the distal and proximal interphalangeal joints. It tends not to involve the metacarpophalangeal joints, although it can in severe cases. Of course, the first carpometacarpal joint is frequently involved, and OA in this joint can be very disabling.
I have patients, for example, who are pianists or people who use their hands in their daily occupation. Their problem is often unfortunately minimized, with the doctor saying, “Oh, you’ve got a touch of OA, you can live okay with it.” However, this is hard to do because of pain and decreased function—OA can be a very disabling disease. In a number of women, the joints of the hands can be very inflamed. There’s a form of hand OA called erosive inflammatory OA, which can be especially troublesome because it’s very destructive. It’s almost like a low-grade rheumatoid arthritis where you actually get a lot of joint breakdown and deformity—it can be very disabling. OA of the knees or hips obviously can be a problem because of difficulties with ambulation.
DR. BLOCK: Our medical model trains us that, in general, we should look for an abnormality on a laboratory test to make a diagnosis. We do look for radiographic evidence of OA because, as I have said several times already, almost every elderly patient will have radiographic evidence of OA-like degeneration; however, we primarily use radiography adjunctively to make sure nothing else is going on or to assess the severity of the degeneration.
We make a diagnosis purely clinically. We look for someone who has the appropriate degree of pain in specific joints and does not have evidence of a systemic inflammatory source of that pain or a systemic rheumatic disease and in whom the pain appears to be articular rather than extra-articular. Of course, clinically, we feel for crepitus when we move the joint because of the degenerative processes, and we feel for bony enlargements or osteophytes around the joint to assist in making the diagnosis of OA.
Radiography is helpful in the sense that it can tell us about the severity of the degeneration and help us to make sure that we’re not missing something else such as a malignancy; however, radiography itself is not critical for the clinical diagnosis of OA.
DR. GALL: Dr. Block, how can the clinician who first sees a patient with OA differentiate it from a common type of inflammatory arthritis such as rheumatoid arthritis?
DR. MOSKOWITZ: If I may comment on that; you’re looking at 2 things. First, you are looking for symptoms and signs that you expect to be associated with OA, and then, you are looking for signs and symptoms that are not consistent with OA. As we said earlier, you may get some inflammation in the knee. You may get some swelling, and you can have evidence of increased synovial fluid, but you wouldn’t have the diffuse inflammatory reaction that you would have in rheumatoid arthritis, and there are different joints involved. For example, in rheumatoid arthritis, there may be involvement of the proximal interphalangeal and metacarpophalangeal joints of the hands, wrists, elbows, or shoulders. You would have involvement of peripheral joints that are different from those that are characteristically involved with OA.
In OA, the patient doesn’t have systemic findings such as fever, weight loss, or generalized prolonged stiffness. The patient often has localized stiffness in the involved joint but not generalized stiffness like that seen in rheumatoid arthritis. In OA, you can have multiple joints involved, such as 2 knees and 1 hip, but involvement doesn’t come on all at once and with the same severity.
DR. BLOCK: I completely agree with everything Dr. Moskowitz said. Additionally, if one is still confused after all of the clinical signs, this is where radiography may be useful because the radiographic appearance of OA is really different from that of the inflammatory arthritides.
In OA, one expects asymmetric narrowing in the joint itself. Additionally, OA results in subchondral sclerosis instead of periarticular osteopenia, which is seen in inflammatory arthritis. Finally, often, in OA, there is osteophyte formation, which is in contrast to the erosions that may be seen in the inflammatory arthritides. This is one area where radiography can really help.
DR. MOSKOWITZ: You have to be careful with respect to diagnosis in older people because if you do a serum rheumatoid factor study, the rheumatoid factor may be positive, but this may be unrelated to the patient’s symptoms. Studies have shown that a positive rheumatoid factor may be nonspecifically related to aging. So, you have to be careful—this finding can be a red herring in the diagnosis.
DR. BLOCK: I agree completely, and because OA is so common, one needs to bear in mind that a patient might have both inflammatory arthritis and underlying OA at the same time.
DR. MOSKOWITZ: Great point. We all see patients who come in to the office with OA of the hands, and then they develop rheumatoid arthritis or lupus engrafted on that previous involvement.
DR. GALL: I’d like to move on now to the management of the disease and, Dr. Moskowitz, would you talk to us about the first approach, which would be prevention? This is an approach that has caught the attention of the Centers for Disease Control and the Arthritis Foundation, and there is a major ongoing campaign at this time about what we can do to prevent this disease. Could you summarize that for us, Dr. Moskowitz?
DR. MOSKOWITZ: Absolutely. It’s generally thought that there’s nothing you can do to prevent OA. Well, we now think that you can slow it down and perhaps prevent it. Number one, we talked about weight. If a patient were to lose just 10 or 12 pounds, that could have a significant impact on the destructive effect of weight on the progression or the development of the disease. Programmed exercise is also very important. People say, “Well, I have arthritis. I can’t exercise,” and this is a problem because if you’re overweight and you have OA of the knees, joint overuse may temporarily lead to more symptoms. But walking at a reasonable pace and duration can be helpful with respect to symptoms and disability—the body puts out pain-relieving endorphins, muscles are strengthened, and joint range-of-motion is improved. Walking on a treadmill at a reasonable pace helps to achieve weight loss.
The patient can walk on a prescribed basis according to his or her capabilities. It’s important not to ask the patient to do something you know they’re not going to be able to do. We wouldn’t ask them to lose 20 pounds in the next 2 months. We have to make the program practical—these things are not easy to do, so we’ve got to be very supportive.
While trying to prevent disease progression, you want to have the patient strengthen their joint-related muscles. You want them to do muscle-building exercises because if you have joint stability, you’re likely going to decrease the osteoarthritic process as well. Losing weight is very important. Exercise is important. Using hot and cold applications for local therapy, which is safer than medication, is helpful.
Importantly, you don’t want to limit the patient’s activities any more than necessary. The way that I’ve always practiced medicine is that you don’t want to take away the patient’s ability to live his or her life as normally as possible. You don’t want to prescribe “don’ts,” like “don’t walk” and “don’t climb steps.” You want the patient to walk and do exercises, but the exercises have to be programmed so that the patient is able to do them.
DR. GALL: This is actually a very common question that primary care physicians are faced with when a patient with this disease comes in and is afraid to exercise and has a difficult time losing weight. But, I think it’s important that we understand that the cartilage gets its nourishment by being compressed and released and it has no blood supply of its own, so a lack of exercise is going to further cartilage degeneration.
DR. MOSKOWITZ: There are other non-weight bearing activities such as aquatic exercises that most people can do. You don’t have to be able to swim. You can do water exercises where you have the buoyancy of the water allowing for passive assistive exercise.
DR. BLOCK: Let me just add one other thing to the exercise discussion. In addition to there being a structural benefit to controlled exercise, every single systematic evaluation that has been performed has demonstrated that there is a really substantial and sustained pain relief component to exercise. People who have OA who are able to exercise regularly get substantial pain relief just from the exercise, and this is really important because the pain is what’s slowing them down in the first place.
The problem, of course, is maintaining an exercise regimen for a long term. Remember, this is a disease of decades, and we are not that good at behavioral modification strategies. Patients often give up on the exercise after a while. But, if you can maintain it, there are structural benefits as well as really substantial pain relief benefits.
DR. MOSKOWITZ: Yes, I agree. The other thing is that it’s hard for the busy physician in the office to start teaching the patient how to exercise, so we need to use arthritis health professionals such as occupational therapists and physical therapists to create exercise programs and teach patients how to exercise more effectively.
DR. BLOCK: Can I add one more thing as long as we’re discussing prevention? One of the major societal risk factors right now is recreational trauma. We have a population of young individuals who are being brought up in various organized sports, and there’s a very substantial risk factor for adolescent and young women who are, for example, playing soccer. They are getting knee and anterior cruciate ligament injuries, and over the upcoming 10 to 15 years, these people are at an enormous risk for developing knee OA. So, we need to develop some strategies to reduce the recreational trauma that results in early OA in this population.
DR. GALL: So, now we realize that weight control and exercise are important. Can we now talk about the medical management of both the pain and the arthritis?
DR. MOSKOWITZ: I know we don’t want to take too much time with this, but before we finish, I wanted to mention that I keep getting asked about tai chi or acupuncture for treatment. There are data suggesting that these programs can be helpful, but they should be adjunctive considerations for patients not responding to more routine therapeutic programs.4
DR. GALL: Yes, I would certainly agree with that. These are adjunctive therapies that may be helpful in select patients, but we need to focus on the more proven aspects of the prevention of the disease. Let’s now divide our talk about treatment into pain management and disease management. Can we start with pain management?
DR. BLOCK: I think that, first of all, it’s really important not to neglect the adjunctive measures that we’ve already discussed, and so, pain management is multifactorial, but one needs to include a physical and occupational therapist because although regular exercise dramatically reduces pain, local measures such as heat or ice are often very useful.
When they don’t get sufficient relief from adjunctive measures, symptomatic patients with OA will need to move to the pharmacologic arena sooner or later. From my practice and from the literature, I would say that there are 2 kinds of pain that need to be treated in OA: Pain that occurs during a painful flare that may last a couple of weeks and chronic ongoing pain that may develop as the disease progresses.
During short painful flares, most of the organizations that have published guidelines over the years have suggested that acetaminophen is a good place to start.5,6 I think that the systematic literature at this point suggests that acetaminophen might be very good for short-term pain relief—meaning, a few weeks at most. It’s probably not very effective for long-term pain relief, and it has a fair amount of potential complications, especially in the elderly. I don’t tend to use a lot of acetaminophen in people who are having chronic pain from OA, but during short-term pain flares, it can be very useful.
One can choose various analgesics including topical nonsteroidal agents, which can be very effective for local and monoarticular pain, for example, pain in superficial joints such as the knees or fingers. However, sooner or later, I believe that if patients don’t have a contraindication, they will end up taking either nonsteroidal anti-inflammatory agents (NSAIDs) or COX-2 inhibitors (coxibs), and that’s probably for a good reason. The nonsteroidals and coxibs have been demonstrated repeatedly to retain pain relief during 2-year studies, and they’re almost unique among the pharmacologic agents in that they retain that pain relief over a couple of years.7,8
Of course, if people are undergoing adequate pharmacologic therapy and they have painful flares in single joints, then intra-articular therapies such as glucocorticoids or hyaluronans are often very effective.
DR. GALL: I’d like to just go back to the NSAIDs for a moment. There is increasing emphasis on the risk of NSAIDs, particularly in the elderly. How do we balance the benefits of NSAID use for chronic therapy versus the risks, and how would you monitor the patient?
DR. MOSKOWITZ: Well, I agree with the premises that Dr. Block mentioned. I think acetaminophen has varying efficacy, but I think it’s worth trying. If I am right, I think it was stated in the past that the acetaminophen dose could go up to 4 g/d.9 The current recommendation is that doses of acetaminophen should not exceed 3 g/d so as not to incur hepatic or renal toxicity. The problem is that acetaminophen is often present in other medicines that patients are taking, and so an excess total intake is not uncommon.10
I think a trial of acetaminophen is worthwhile because even if it doesn’t relieve all the pain, it’s a floor of analgesia that you can add to with nonsteroidals.
With regard to the question about whether nonsteroidals are dangerous in older people, I think that they can be. Most things we use are unfortunately associated with some risk, although pain itself is also a risk factor. Pain increases blood pressure and pulse rate. If you relieve the pain, you’re probably relieving more of the stress on the patient overall as opposed to the risk of the NSAID itself. If you use nonselective NSAIDs, I would suggest adding a proton pump inhibitor, especially if the patient has an increased risk of peptic ulcer disease. If you use a COX-2 selective inhibitor, data suggest there is a decreased gastrointestinal (GI) risk. Overall, I think that NSAIDs can be effective and reasonably safe. I’m more careful about using NSAIDs in individuals older than 75 or 80 years; however, many of these patients are physiologically younger than their numerical age, and they can more safely tolerate these agents.
Intra-articular steroids and intra-articular hyaluronans can be very helpful in the management of knee OA, and they have comfortable safety factors.
DR. GALL: I’ll just make a comment about my own approach to that. When I put a patient on an NSAID, and I do use them frequently, I mark it on a problem list. I’m careful to ask the patients about bleeding and to warn them about the signs of GI bleeding, and I do periodic blood counts to look at hemoglobin and creatinine levels. I also do a urinalysis to rule out silent GI or renal effects of these drugs, but I do use NSAIDs frequently.
Additionally, with the recent attention to the pain component of OA over the past decade, there has been a lot of systematic investigation into various neuroactive pain-directed medications. In fact, duloxetine, which is a neuroactive agent, was approved for use a couple of years ago. There are non–anti-inflammatory, non-purely analgesic medicines that can be very helpful for the treatment of the pain component of OA.
DR. GALL: Thank you. Could we just say a word about opioids and tramadol as adjunctive therapies and what the pluses and minuses of using these drugs are?
DR. MOSKOWITZ: I think there is not only a rationale but a place for these agents in treating OA, but we’ve got to be careful. I’m a little less concerned about using tramadol than using the classic opioids, per se, and I think tramadol can be a reasonable bridge when people are not responding to NSAIDS. A number of years ago, when I was writing a piece for the Arthritis Foundation pamphlet, I stated that there is never a place for opioids in the treatment of OA, and I can’t tell you how many of my colleagues wrote and said, “Dr. Moskowitz, there are times when we feel they need to be available.” I agree, but I think my guidance is that, if you use an opioid, use the lowest dose possible and for the shortest time possible.
I think if someone is in a lot of pain and they’re having a flare, particularly an older individual, it may be safer to use the opioids than to put them on NSAIDs, particularly if they have had past trouble with NSAIDS. I don’t think that we should never use opioids when treating OA. What are your thoughts on that, Dr. Block?
DR. BLOCK: I agree. I think that there is good evidence that the opiates provide really substantial pain relief, so they’re effective in OA. The problem, of course, is that they have very high side effect profiles, and the people that they’re the most dangerous for with regard to falling and injuring oneself are actually the same people who are at high risk with nonsteroidals—the very elderly with congestive heart failure. It really does put us in a bind.
I think that I agree with what you just said, which is that they are effective, and at times, I think that there is clearly a place for opiates in OA, but one needs to be judicious and careful when using them. Tramadol is, I think, much safer. It’s a weak opiate. On the other hand, it also has much less pain-relieving potential, so this is the bind we face.
Well, I think what we haven’t mentioned yet are the surgical approaches, which are critically important.
DR. MOSKOWITZ: Should we discuss glucosamine and chondroitin sulfate?
DR. BLOCK: So, more than half of patients who have symptomatic OA use various complementary medicine approaches. They are widely used because they’re widely believed to be beneficial, and I think that there has been a fair amount of systematic evaluation, specifically of glucosamine and chondroitin sulfate, over the past several years.
When we look at the independently sponsored studies, the evidence suggests that the side effect profile for both agents is very good. As long as they were manufactured in a safe manner, they are very safe and one shouldn’t worry about using them.
On the other hand, the efficacy above placebo is very low, but that doesn’t mean that they’re not effective in individual patients. The thing that’s really important to note here is that whenever there is a placebo-controlled study with pain as an outcome in OA, the placebo response is huge. More than half of the people who get placebo get very substantial clinically significant pain relief, and more importantly, it’s durable. In all of these placebo-controlled studies that go on for 2 years, the placebo group with pain relief had sustainability over 2 years,11,12 and so, if one gets more than a placebo response from glucosamine, and if it’s providing pain relief, I’m happy for them to use it.
The Glucosamine/Chondroitin Arthritis Intervention Trial (GAIT),7 the large National Institutes of Health multicenter study, which was a null study, showed that fundamentally, there was no systematic advantage of a combination glucosamine plus chondroitin sulfate. Even when that came out as a null study and was publicized as such, the market for glucosamine and chondroitin sulfate in the following year didn’t decrease in the United States.13,14
People who are getting a benefit, whether it’s due to an endorphin effect from placebo or the agent, are going to continue using the agent. As long as the agents are safe, I’m comfortable with my patients using them if they really are feeling like they are getting relief.
DR. MOSKOWITZ: Yes, I think that there are conflicting data, but there are a number of studies that seem to show that these agents do help some people. For example, this question about the GAIT study7 not showing an effect, if you’re using glucosamine and chondroitin sulfate in individuals who have high pain to start with—if they had a score of more than 300 mm on the Western Ontario and McMaster Universities Arthritis Index (WOMAC)—they appeared to do better, but there wasn’t a predefined endpoint, so the result has to be substantiated in a repeat study. However, I see enough people—like you do, Dr. Block—who seem to respond. They’re safe agents, and I think that they do have merit in patients who are not getting a benefit from other agents.
DR. GALL: Before we move on to surgery and the future of therapy, I just want to discuss intra-articular steroids. What are your thoughts on these?
DR. MOSKOWITZ: I would be lost without them. I remember when they were first used by Dr. Joseph Hollander in Philadelphia, and they failed to help because he used cortisone acetate instead of the hydrocortisone derivative, and cortisone has to be converted to hydrocortisone before it works.15 I use intra-articular corticosteroids a lot. The general recommendation is that you shouldn’t use it more than 4 times a year in the knee. I think maybe if somebody is older—for example, 88 years—and they cannot tolerate other therapy, you might use them that often. Studies have shown that an intra-articular corticosteroid injection every 3 months did not lead to deleterious anatomic effects.16 I think using them 2 or 3 times a year, if indicated, can be symptomatically effective and safe, and I don’t think that will lead to joint breakdown if the patient is careful about doing their exercises and other management.
DR. GALL: Let’s move on to the use of surgery, and without going into all the surgical procedures, when is it appropriate for the clinician and the patient to consider surgical intervention in OA?
DR. BLOCK: It is entirely patient-oriented. You can’t tell by structure or by X-ray. When the patient’s OA is painful and severe enough, when it cannot be controlled with medication and medical regimens, or when it’s interfering with their lifestyle and they can’t live with it, they’ll tell you they need surgery.
DR. MOSKOWITZ: I completely agree. I think you can’t tell them. They’ll let you know. They’ll say, “I just have so much pain and disability. I need something done.”
DR. GALL: I think it’s important also to bring the surgeon in, not as a plumber to fix something, but as a partner in making the decision. Certainly the primary care physician, often the rheumatologist, can also provide guidance and work with the patients and the surgeons in making that decision.
DR. MOSKOWITZ: Yes. Let me just add one thing: I don’t think the patient should be in an extreme state of pain and disability in order to have surgery. If the condition interferes with their ADLs and the pain is really encumbering their daily activities, then it’s not unreasonable to consider surgery. I don’t think they have to be so bad that they’re limping and in terrible distress.
DR. BLOCK: Having said that, we should mention that joint replacement, at least in the knees and the hips, is extraordinarily effective in relieving pain.
DR. GALL: Yes. I would agree and these advances have continued to increase over the years, and these replacements last for a longer period of time, so the amount of satisfaction has increased, and the number of complications in experienced centers has certainly decreased.
Let’s end by talking about the future of OA. There are 2 areas that I’d like to touch on: One is the disease-modifying OA drugs (DMOADs) and the other is cartilage regeneration with stem cells and other techniques. Dr. Moskowitz, maybe you can talk about the DMOADs, and Dr. Block, you can talk about cartilage regeneration.
DR. MOSKOWITZ: Disease retardation or reversal would be the holy grail of OA management: to be able to treat OA with medications—the so-called DMOADS—that not only relieve symptoms but also slow the disease down or actually reverse the disease process. Some of the agents described as possibly having disease-modification potential include glucosamine, chondroitin sulfate, intra-articular hyaluronans, diacerein, avocado/soybean unsaponifiables, and doxycycline among others.17 Further studies will help to define the purported role of such agents in disease modification.
DR. BLOCK: I think it’s fair to say that, as of today, there really are no strategies that have been proven to be effective at retarding the progression and pain of OA over long periods of time. I think that is the gold standard that we’re looking for, and there is suggestive evidence from studies performed on each of the agents that Dr. Moskowitz just mentioned and several others.
I think there is a lot of work being done to study various metalloproteinase inhibitors, especially the collagenase 3 (MMP-13) inhibitors, and the aggrecanase inhibitors. I think that if some of these things are demonstrated to be effective in delaying the progression of OA, they could be extremely exciting, but one needs to keep in mind that whatever we use as a DMOAD has to be extremely safe because it’s going to be used for decades in people who are basically asymptomatic. In order to justify that on a public health basis, it has to be extraordinarily safe. It’s a very high bar.
DR. GALL: Okay. Dr. Block, can you now attempt to discuss cartilage regeneration and the use of the stem cell?
DR. BLOCK: Yes. Mesenchymal stem cell technology is extremely exciting, and it has paid off in some areas of bone and other connective tissues. As everybody knows, there is one U.S. Food and Drug Administration-approved approach for replacing cartilage that has had some success, but it’s used for isolated chondral defects in young and otherwise healthy people—not for OA.
The problem, of course, is that as we understand OA better and better, it’s more than just cartilage degeneration, and more importantly, the cartilage, which is very important, is a very thin and delicate tissue. If we replace the cartilage alone without normalizing the aberrant biomechanics across the joint—without normalizing the subchondral bone that the cartilage sits on—we have very little chance of getting long-term relief.
Having said that, efforts are being carried out in a variety of laboratories around the world to focus on not only mesenchymal cell-directed cartilage formation but also on actual repair of most tissues of the joint. Once we understand how to grow new cartilage and actually have it integrate with the adjacent tissue, which we still are not able to do, and once we’re able to repair some of the subchondral bone, I think that there is a lot of promise for that strategy in the long run. But, in the short-term, again, it’s a very difficult process that is not yet well understood.
DR. MOSKOWITZ: Well said. I agree. I think that we’re on the brink of being able to repair, particularly, very focal defects—maybe 4- or 5-mm defects. But, to repair the joint, as Dr. Block pointed out, you can’t just repair the cartilage because joint changes such as inflammation, meniscal alterations, varus and valgus deformities, and other changes impacting the joint are going to impair cell-based regeneration. Until we get those impacts controlled, I think it’s going to be some time before we can say to someone, “We’re going to replace your cartilage and normalize your joint.” However, I am optimistic and think that down the line, we may be able to do it.
DR. GALL: Dr. Block also mentioned that the underlying bone has changed too, and so, that needs to be attacked as well in these approaches.
DR. BLOCK: My personal view is that in the short-term future—the next 5 to 10 years—big strides will be made in strategies for better pain relief, and there are a variety of biologics that are in phase II and phase III testing that already look very exciting. Again, my own personal research interest is in trying to normalize the mechanical loads across the joints so that we can protect the joints better and so that the OA won’t progress, and I think those kinds of strategies will be available over the next couple of years.
DR. GALL: I’d like to thank you both for a really enlightening and comprehensive discussion of this common disease. Just to review, we’ve discussed what OA is and defined it, talked about its burden and its diagnosis, and mentioned the various risk factors for OA, particularly in light of what we can do to prevent OA or prevent the progression of the disease. We also had a comprehensive talk about the treatment of OA from both the standpoint of pain and the actual disease, and we touched upon the future of this as well as the research that’s being done in these areas.
I really appreciate your wisdom and discussion, and I think we’re providing the primary care physicians and providers with a really comprehensive look at this disease.

DR. BLOCK: Throughout the 20th century, we always considered OA to be primarily a degenerative disease of cartilage, but during the past decade or more, 2 things have become apparent: First, from a clinical perspective, OA is not just a structural degenerative process, it is primarily a very painful disease with pain being its most prominent feature. Second, the degenerative process involves not only the cartilage but the entire joint and all the involved structures within it.
A reasonable working definition of OA right now would be a painful degenerative process involving all the joint structures and is not primarily inflammatory but involves progressive deterioration of joint structures including articular cartilage. It’s important to keep in mind that pain itself is critical because as individuals age, everybody has some degenerative processes in their joints, and if we look hard enough, we can find the pathological features of OA in all elderly people. However, not all elderly people actually have the clinical disease.
DR. GALL: In a moment, we’ll talk about the causes of this, but, Dr. Moskowitz, would you tell us what the burden of this disease is here in the United States and worldwide?
DR. MOSKOWITZ: Well, it’s the most common form of arthritis and affects nearly 27 million or more Americans.1 It’s the most common disabling disease of the rheumatologic group, and it’s very disabling among all diseases.
DR. GALL: In the United States, you say that there’s about—
DR. MOSKOWITZ: About 27 million people with OA. And, in a decade, it is anticipated that the number will significantly increase.
DR. GALL: How many of those people are affected to the point that they’re unable to do their normal activities of daily living (ADLs)?
DR. MOSKOWITZ: Well, in terms of disability, about 80% of patients with OA have some degree of movement limitation, 25% cannot perform major ADLs, 11% of adults with knee OA need help with personal care, and 14% require help with routine needs.2
DR. GALL: Dr. Block, you talked about pain as a major manifestation of this disease. Does everybody who has OA present with pain?
DR. BLOCK: Again, it’s a definitional question; there is a distinction between clinically evident OA and asymptomatic structural degeneration of the joint. The population that Dr. Moskowitz was just describing, which comprises 20 to 30 million people, has doctor-diagnosed symptomatic OA, which is a painful disease. A much higher number of people who have structural degenerative disease would be diagnosed by radiography and said to fulfill a radiographic definition of OA, but all of the people who Dr. Moskowitz refer to have pain.
DR. MOSKOWITZ: Pain is what brings a patient to the doctor. I’ll often ask my patients, “How are you doing and what can I do for you?” They have limited motion and can’t get around. They say, “Dr. Moskowitz, I just want to get rid of the pain. I’ll worry about the swelling and getting around later.” And, that’s what really motivates them to get medical attention.
DR. GALL: Often, we will get consultations from primary care physicians for a patient who has OA that’s been picked up by radiography, and the patients will come and really not complain of pain in that area or possibly might have another underlying disease that’s causing the pain that’s not related to the OA. Dr. Block, do you want to say a word about that?
DR. BLOCK: Sure. By the age of 80 years, essentially, 100% of the population will have evidence of radiographic OA in at least one of their large joints. If you start with that number and you’re then referred an elderly patient merely for the radiographic appearance of OA, that doesn’t tell you very much about what’s going on clinically, and so, most of us would not even describe that as a clinical disease.
They may have a degenerative process in their knee, hip, etc, but of that group, say at the age of 80 years where almost 100% of people will have radiographic evidence of OA, only about 15% to 20% have symptomatic disease.3 That’s the culprit that I think we’re talking about clinically—people who not only have degenerative structural disease but also have symptoms that are interfering with their quality of life or their daily activities.
DR. MOSKOWITZ: I think that’s an important point, Dr. Block. For example, we all see patients who come in complaining of hip pain and you examine their knees as well and they have terrible genu varum (bowleg) and you say, “Do your knees bother you?” and they say, “Doctor, my knees are fine.” You think, my goodness, how can you walk? It isn’t necessarily true that if you have a deformity or involvement of a joint that you’re going to have pain, but if you have painful joints, that brings you to the doctor.
DR. GALL: Dr. Block, once again, I would like you to summarize the etiology of OA. Obviously, there has been much research and much information that has come to light in recent years regarding the causes of this disease.
DR. BLOCK: As I said, throughout the 20th century, people interested in the pathophysiology of OA were quite convinced that it was a degenerative process of the articular cartilage. As people age, the articular cartilage starts degenerating, and when there is absence of intact cartilage that ought to be providing essentially frictionless articulation of the bones during motion, there is deterioration, and that’s what we always considered to be OA.
Of course, the missing link in that paradigm is that cartilage itself has no nerve or blood supply and is therefore painless, and yet, people have horrible pain with this disease. So, our understanding over the past 10 or 15 years has really dramatically progressed, and we have begun to appreciate both degenerative and reactive processes in the subchondral bone, the ligaments, and the muscle.
The way we look at the pathophysiology of the onset and progression of the disease today is that there is primarily a degenerative process that stimulates reactive processes throughout the joint and even in the immune and inflammatory pathways. So, the reaction to that degenerative process sometimes causes stimulation of nociceptors and a lot of pain because of either local inflammation or mechanical alterations.
The degeneration itself, as I said, is painless. Often, people can have very degenerative joints, as Dr. Moskowitz just mentioned, and have no pain and therefore no clinical symptoms, so the disease is a combination of the degeneration and the secondary stimulated pain.
DR. GALL: So, is this primarily a biochemical or a cellular disease? Is it a genetic disease?
DR. BLOCK: Yes to all.
DR. MOSKOWITZ: There are a number of factors, Dr. Gall, involved in this condition. First, for example, is aging. We see that the frequency of OA increases logarithmically as we age, and there are pathologic changes with age that appear to lead to OA. For example, pigmented collections in the joint, comprising advanced glycation end products, occur that may predispose a patient to OA. You’re going to find more OA in an aging population.
The second factor is trauma. Professional football and basketball players, for example, who have chronic trauma, meniscal injuries, or cruciate ligament injuries are predisposed to OA. Third—the big risk factor, of course—is being overweight or obese. Patients who are overweight have a much higher frequency of OA, particularly in the knees. Last, there are genetic factors. For example, OA in the hands, which is more often seen in women, is genetically oriented so that if your mother had it or your aunt had it, you’re more likely to get it. Accordingly, there are multifactorial etiological factors that we have to try to address.
DR. GALL: Can you say a word about the different areas of the body that are associated with OA and talk a little bit about the difference between OA of the hands that we see frequently in women in relation to OA of the knee, hips, and spine, which can be devastating for individuals?
DR. MOSKOWITZ: Any joint can have it. It can be in the ankle, for example, if there has been trauma, but we’re looking particularly at the knees, the hips, the hands, and the spine. It’s interesting—certain joints in the hands are predisposed to OA including the distal and proximal interphalangeal joints. It tends not to involve the metacarpophalangeal joints, although it can in severe cases. Of course, the first carpometacarpal joint is frequently involved, and OA in this joint can be very disabling.
I have patients, for example, who are pianists or people who use their hands in their daily occupation. Their problem is often unfortunately minimized, with the doctor saying, “Oh, you’ve got a touch of OA, you can live okay with it.” However, this is hard to do because of pain and decreased function—OA can be a very disabling disease. In a number of women, the joints of the hands can be very inflamed. There’s a form of hand OA called erosive inflammatory OA, which can be especially troublesome because it’s very destructive. It’s almost like a low-grade rheumatoid arthritis where you actually get a lot of joint breakdown and deformity—it can be very disabling. OA of the knees or hips obviously can be a problem because of difficulties with ambulation.
DR. BLOCK: Our medical model trains us that, in general, we should look for an abnormality on a laboratory test to make a diagnosis. We do look for radiographic evidence of OA because, as I have said several times already, almost every elderly patient will have radiographic evidence of OA-like degeneration; however, we primarily use radiography adjunctively to make sure nothing else is going on or to assess the severity of the degeneration.
We make a diagnosis purely clinically. We look for someone who has the appropriate degree of pain in specific joints and does not have evidence of a systemic inflammatory source of that pain or a systemic rheumatic disease and in whom the pain appears to be articular rather than extra-articular. Of course, clinically, we feel for crepitus when we move the joint because of the degenerative processes, and we feel for bony enlargements or osteophytes around the joint to assist in making the diagnosis of OA.
Radiography is helpful in the sense that it can tell us about the severity of the degeneration and help us to make sure that we’re not missing something else such as a malignancy; however, radiography itself is not critical for the clinical diagnosis of OA.
DR. GALL: Dr. Block, how can the clinician who first sees a patient with OA differentiate it from a common type of inflammatory arthritis such as rheumatoid arthritis?
DR. MOSKOWITZ: If I may comment on that; you’re looking at 2 things. First, you are looking for symptoms and signs that you expect to be associated with OA, and then, you are looking for signs and symptoms that are not consistent with OA. As we said earlier, you may get some inflammation in the knee. You may get some swelling, and you can have evidence of increased synovial fluid, but you wouldn’t have the diffuse inflammatory reaction that you would have in rheumatoid arthritis, and there are different joints involved. For example, in rheumatoid arthritis, there may be involvement of the proximal interphalangeal and metacarpophalangeal joints of the hands, wrists, elbows, or shoulders. You would have involvement of peripheral joints that are different from those that are characteristically involved with OA.
In OA, the patient doesn’t have systemic findings such as fever, weight loss, or generalized prolonged stiffness. The patient often has localized stiffness in the involved joint but not generalized stiffness like that seen in rheumatoid arthritis. In OA, you can have multiple joints involved, such as 2 knees and 1 hip, but involvement doesn’t come on all at once and with the same severity.
DR. BLOCK: I completely agree with everything Dr. Moskowitz said. Additionally, if one is still confused after all of the clinical signs, this is where radiography may be useful because the radiographic appearance of OA is really different from that of the inflammatory arthritides.
In OA, one expects asymmetric narrowing in the joint itself. Additionally, OA results in subchondral sclerosis instead of periarticular osteopenia, which is seen in inflammatory arthritis. Finally, often, in OA, there is osteophyte formation, which is in contrast to the erosions that may be seen in the inflammatory arthritides. This is one area where radiography can really help.
DR. MOSKOWITZ: You have to be careful with respect to diagnosis in older people because if you do a serum rheumatoid factor study, the rheumatoid factor may be positive, but this may be unrelated to the patient’s symptoms. Studies have shown that a positive rheumatoid factor may be nonspecifically related to aging. So, you have to be careful—this finding can be a red herring in the diagnosis.
DR. BLOCK: I agree completely, and because OA is so common, one needs to bear in mind that a patient might have both inflammatory arthritis and underlying OA at the same time.
DR. MOSKOWITZ: Great point. We all see patients who come in to the office with OA of the hands, and then they develop rheumatoid arthritis or lupus engrafted on that previous involvement.
DR. GALL: I’d like to move on now to the management of the disease and, Dr. Moskowitz, would you talk to us about the first approach, which would be prevention? This is an approach that has caught the attention of the Centers for Disease Control and the Arthritis Foundation, and there is a major ongoing campaign at this time about what we can do to prevent this disease. Could you summarize that for us, Dr. Moskowitz?
DR. MOSKOWITZ: Absolutely. It’s generally thought that there’s nothing you can do to prevent OA. Well, we now think that you can slow it down and perhaps prevent it. Number one, we talked about weight. If a patient were to lose just 10 or 12 pounds, that could have a significant impact on the destructive effect of weight on the progression or the development of the disease. Programmed exercise is also very important. People say, “Well, I have arthritis. I can’t exercise,” and this is a problem because if you’re overweight and you have OA of the knees, joint overuse may temporarily lead to more symptoms. But walking at a reasonable pace and duration can be helpful with respect to symptoms and disability—the body puts out pain-relieving endorphins, muscles are strengthened, and joint range-of-motion is improved. Walking on a treadmill at a reasonable pace helps to achieve weight loss.
The patient can walk on a prescribed basis according to his or her capabilities. It’s important not to ask the patient to do something you know they’re not going to be able to do. We wouldn’t ask them to lose 20 pounds in the next 2 months. We have to make the program practical—these things are not easy to do, so we’ve got to be very supportive.
While trying to prevent disease progression, you want to have the patient strengthen their joint-related muscles. You want them to do muscle-building exercises because if you have joint stability, you’re likely going to decrease the osteoarthritic process as well. Losing weight is very important. Exercise is important. Using hot and cold applications for local therapy, which is safer than medication, is helpful.
Importantly, you don’t want to limit the patient’s activities any more than necessary. The way that I’ve always practiced medicine is that you don’t want to take away the patient’s ability to live his or her life as normally as possible. You don’t want to prescribe “don’ts,” like “don’t walk” and “don’t climb steps.” You want the patient to walk and do exercises, but the exercises have to be programmed so that the patient is able to do them.
DR. GALL: This is actually a very common question that primary care physicians are faced with when a patient with this disease comes in and is afraid to exercise and has a difficult time losing weight. But, I think it’s important that we understand that the cartilage gets its nourishment by being compressed and released and it has no blood supply of its own, so a lack of exercise is going to further cartilage degeneration.
DR. MOSKOWITZ: There are other non-weight bearing activities such as aquatic exercises that most people can do. You don’t have to be able to swim. You can do water exercises where you have the buoyancy of the water allowing for passive assistive exercise.
DR. BLOCK: Let me just add one other thing to the exercise discussion. In addition to there being a structural benefit to controlled exercise, every single systematic evaluation that has been performed has demonstrated that there is a really substantial and sustained pain relief component to exercise. People who have OA who are able to exercise regularly get substantial pain relief just from the exercise, and this is really important because the pain is what’s slowing them down in the first place.
The problem, of course, is maintaining an exercise regimen for a long term. Remember, this is a disease of decades, and we are not that good at behavioral modification strategies. Patients often give up on the exercise after a while. But, if you can maintain it, there are structural benefits as well as really substantial pain relief benefits.
DR. MOSKOWITZ: Yes, I agree. The other thing is that it’s hard for the busy physician in the office to start teaching the patient how to exercise, so we need to use arthritis health professionals such as occupational therapists and physical therapists to create exercise programs and teach patients how to exercise more effectively.
DR. BLOCK: Can I add one more thing as long as we’re discussing prevention? One of the major societal risk factors right now is recreational trauma. We have a population of young individuals who are being brought up in various organized sports, and there’s a very substantial risk factor for adolescent and young women who are, for example, playing soccer. They are getting knee and anterior cruciate ligament injuries, and over the upcoming 10 to 15 years, these people are at an enormous risk for developing knee OA. So, we need to develop some strategies to reduce the recreational trauma that results in early OA in this population.
DR. GALL: So, now we realize that weight control and exercise are important. Can we now talk about the medical management of both the pain and the arthritis?
DR. MOSKOWITZ: I know we don’t want to take too much time with this, but before we finish, I wanted to mention that I keep getting asked about tai chi or acupuncture for treatment. There are data suggesting that these programs can be helpful, but they should be adjunctive considerations for patients not responding to more routine therapeutic programs.4
DR. GALL: Yes, I would certainly agree with that. These are adjunctive therapies that may be helpful in select patients, but we need to focus on the more proven aspects of the prevention of the disease. Let’s now divide our talk about treatment into pain management and disease management. Can we start with pain management?
DR. BLOCK: I think that, first of all, it’s really important not to neglect the adjunctive measures that we’ve already discussed, and so, pain management is multifactorial, but one needs to include a physical and occupational therapist because although regular exercise dramatically reduces pain, local measures such as heat or ice are often very useful.
When they don’t get sufficient relief from adjunctive measures, symptomatic patients with OA will need to move to the pharmacologic arena sooner or later. From my practice and from the literature, I would say that there are 2 kinds of pain that need to be treated in OA: Pain that occurs during a painful flare that may last a couple of weeks and chronic ongoing pain that may develop as the disease progresses.
During short painful flares, most of the organizations that have published guidelines over the years have suggested that acetaminophen is a good place to start.5,6 I think that the systematic literature at this point suggests that acetaminophen might be very good for short-term pain relief—meaning, a few weeks at most. It’s probably not very effective for long-term pain relief, and it has a fair amount of potential complications, especially in the elderly. I don’t tend to use a lot of acetaminophen in people who are having chronic pain from OA, but during short-term pain flares, it can be very useful.
One can choose various analgesics including topical nonsteroidal agents, which can be very effective for local and monoarticular pain, for example, pain in superficial joints such as the knees or fingers. However, sooner or later, I believe that if patients don’t have a contraindication, they will end up taking either nonsteroidal anti-inflammatory agents (NSAIDs) or COX-2 inhibitors (coxibs), and that’s probably for a good reason. The nonsteroidals and coxibs have been demonstrated repeatedly to retain pain relief during 2-year studies, and they’re almost unique among the pharmacologic agents in that they retain that pain relief over a couple of years.7,8
Of course, if people are undergoing adequate pharmacologic therapy and they have painful flares in single joints, then intra-articular therapies such as glucocorticoids or hyaluronans are often very effective.
DR. GALL: I’d like to just go back to the NSAIDs for a moment. There is increasing emphasis on the risk of NSAIDs, particularly in the elderly. How do we balance the benefits of NSAID use for chronic therapy versus the risks, and how would you monitor the patient?
DR. MOSKOWITZ: Well, I agree with the premises that Dr. Block mentioned. I think acetaminophen has varying efficacy, but I think it’s worth trying. If I am right, I think it was stated in the past that the acetaminophen dose could go up to 4 g/d.9 The current recommendation is that doses of acetaminophen should not exceed 3 g/d so as not to incur hepatic or renal toxicity. The problem is that acetaminophen is often present in other medicines that patients are taking, and so an excess total intake is not uncommon.10
I think a trial of acetaminophen is worthwhile because even if it doesn’t relieve all the pain, it’s a floor of analgesia that you can add to with nonsteroidals.
With regard to the question about whether nonsteroidals are dangerous in older people, I think that they can be. Most things we use are unfortunately associated with some risk, although pain itself is also a risk factor. Pain increases blood pressure and pulse rate. If you relieve the pain, you’re probably relieving more of the stress on the patient overall as opposed to the risk of the NSAID itself. If you use nonselective NSAIDs, I would suggest adding a proton pump inhibitor, especially if the patient has an increased risk of peptic ulcer disease. If you use a COX-2 selective inhibitor, data suggest there is a decreased gastrointestinal (GI) risk. Overall, I think that NSAIDs can be effective and reasonably safe. I’m more careful about using NSAIDs in individuals older than 75 or 80 years; however, many of these patients are physiologically younger than their numerical age, and they can more safely tolerate these agents.
Intra-articular steroids and intra-articular hyaluronans can be very helpful in the management of knee OA, and they have comfortable safety factors.
DR. GALL: I’ll just make a comment about my own approach to that. When I put a patient on an NSAID, and I do use them frequently, I mark it on a problem list. I’m careful to ask the patients about bleeding and to warn them about the signs of GI bleeding, and I do periodic blood counts to look at hemoglobin and creatinine levels. I also do a urinalysis to rule out silent GI or renal effects of these drugs, but I do use NSAIDs frequently.
Additionally, with the recent attention to the pain component of OA over the past decade, there has been a lot of systematic investigation into various neuroactive pain-directed medications. In fact, duloxetine, which is a neuroactive agent, was approved for use a couple of years ago. There are non–anti-inflammatory, non-purely analgesic medicines that can be very helpful for the treatment of the pain component of OA.
DR. GALL: Thank you. Could we just say a word about opioids and tramadol as adjunctive therapies and what the pluses and minuses of using these drugs are?
DR. MOSKOWITZ: I think there is not only a rationale but a place for these agents in treating OA, but we’ve got to be careful. I’m a little less concerned about using tramadol than using the classic opioids, per se, and I think tramadol can be a reasonable bridge when people are not responding to NSAIDS. A number of years ago, when I was writing a piece for the Arthritis Foundation pamphlet, I stated that there is never a place for opioids in the treatment of OA, and I can’t tell you how many of my colleagues wrote and said, “Dr. Moskowitz, there are times when we feel they need to be available.” I agree, but I think my guidance is that, if you use an opioid, use the lowest dose possible and for the shortest time possible.
I think if someone is in a lot of pain and they’re having a flare, particularly an older individual, it may be safer to use the opioids than to put them on NSAIDs, particularly if they have had past trouble with NSAIDS. I don’t think that we should never use opioids when treating OA. What are your thoughts on that, Dr. Block?
DR. BLOCK: I agree. I think that there is good evidence that the opiates provide really substantial pain relief, so they’re effective in OA. The problem, of course, is that they have very high side effect profiles, and the people that they’re the most dangerous for with regard to falling and injuring oneself are actually the same people who are at high risk with nonsteroidals—the very elderly with congestive heart failure. It really does put us in a bind.
I think that I agree with what you just said, which is that they are effective, and at times, I think that there is clearly a place for opiates in OA, but one needs to be judicious and careful when using them. Tramadol is, I think, much safer. It’s a weak opiate. On the other hand, it also has much less pain-relieving potential, so this is the bind we face.
Well, I think what we haven’t mentioned yet are the surgical approaches, which are critically important.
DR. MOSKOWITZ: Should we discuss glucosamine and chondroitin sulfate?
DR. BLOCK: So, more than half of patients who have symptomatic OA use various complementary medicine approaches. They are widely used because they’re widely believed to be beneficial, and I think that there has been a fair amount of systematic evaluation, specifically of glucosamine and chondroitin sulfate, over the past several years.
When we look at the independently sponsored studies, the evidence suggests that the side effect profile for both agents is very good. As long as they were manufactured in a safe manner, they are very safe and one shouldn’t worry about using them.
On the other hand, the efficacy above placebo is very low, but that doesn’t mean that they’re not effective in individual patients. The thing that’s really important to note here is that whenever there is a placebo-controlled study with pain as an outcome in OA, the placebo response is huge. More than half of the people who get placebo get very substantial clinically significant pain relief, and more importantly, it’s durable. In all of these placebo-controlled studies that go on for 2 years, the placebo group with pain relief had sustainability over 2 years,11,12 and so, if one gets more than a placebo response from glucosamine, and if it’s providing pain relief, I’m happy for them to use it.
The Glucosamine/Chondroitin Arthritis Intervention Trial (GAIT),7 the large National Institutes of Health multicenter study, which was a null study, showed that fundamentally, there was no systematic advantage of a combination glucosamine plus chondroitin sulfate. Even when that came out as a null study and was publicized as such, the market for glucosamine and chondroitin sulfate in the following year didn’t decrease in the United States.13,14
People who are getting a benefit, whether it’s due to an endorphin effect from placebo or the agent, are going to continue using the agent. As long as the agents are safe, I’m comfortable with my patients using them if they really are feeling like they are getting relief.
DR. MOSKOWITZ: Yes, I think that there are conflicting data, but there are a number of studies that seem to show that these agents do help some people. For example, this question about the GAIT study7 not showing an effect, if you’re using glucosamine and chondroitin sulfate in individuals who have high pain to start with—if they had a score of more than 300 mm on the Western Ontario and McMaster Universities Arthritis Index (WOMAC)—they appeared to do better, but there wasn’t a predefined endpoint, so the result has to be substantiated in a repeat study. However, I see enough people—like you do, Dr. Block—who seem to respond. They’re safe agents, and I think that they do have merit in patients who are not getting a benefit from other agents.
DR. GALL: Before we move on to surgery and the future of therapy, I just want to discuss intra-articular steroids. What are your thoughts on these?
DR. MOSKOWITZ: I would be lost without them. I remember when they were first used by Dr. Joseph Hollander in Philadelphia, and they failed to help because he used cortisone acetate instead of the hydrocortisone derivative, and cortisone has to be converted to hydrocortisone before it works.15 I use intra-articular corticosteroids a lot. The general recommendation is that you shouldn’t use it more than 4 times a year in the knee. I think maybe if somebody is older—for example, 88 years—and they cannot tolerate other therapy, you might use them that often. Studies have shown that an intra-articular corticosteroid injection every 3 months did not lead to deleterious anatomic effects.16 I think using them 2 or 3 times a year, if indicated, can be symptomatically effective and safe, and I don’t think that will lead to joint breakdown if the patient is careful about doing their exercises and other management.
DR. GALL: Let’s move on to the use of surgery, and without going into all the surgical procedures, when is it appropriate for the clinician and the patient to consider surgical intervention in OA?
DR. BLOCK: It is entirely patient-oriented. You can’t tell by structure or by X-ray. When the patient’s OA is painful and severe enough, when it cannot be controlled with medication and medical regimens, or when it’s interfering with their lifestyle and they can’t live with it, they’ll tell you they need surgery.
DR. MOSKOWITZ: I completely agree. I think you can’t tell them. They’ll let you know. They’ll say, “I just have so much pain and disability. I need something done.”
DR. GALL: I think it’s important also to bring the surgeon in, not as a plumber to fix something, but as a partner in making the decision. Certainly the primary care physician, often the rheumatologist, can also provide guidance and work with the patients and the surgeons in making that decision.
DR. MOSKOWITZ: Yes. Let me just add one thing: I don’t think the patient should be in an extreme state of pain and disability in order to have surgery. If the condition interferes with their ADLs and the pain is really encumbering their daily activities, then it’s not unreasonable to consider surgery. I don’t think they have to be so bad that they’re limping and in terrible distress.
DR. BLOCK: Having said that, we should mention that joint replacement, at least in the knees and the hips, is extraordinarily effective in relieving pain.
DR. GALL: Yes. I would agree and these advances have continued to increase over the years, and these replacements last for a longer period of time, so the amount of satisfaction has increased, and the number of complications in experienced centers has certainly decreased.
Let’s end by talking about the future of OA. There are 2 areas that I’d like to touch on: One is the disease-modifying OA drugs (DMOADs) and the other is cartilage regeneration with stem cells and other techniques. Dr. Moskowitz, maybe you can talk about the DMOADs, and Dr. Block, you can talk about cartilage regeneration.
DR. MOSKOWITZ: Disease retardation or reversal would be the holy grail of OA management: to be able to treat OA with medications—the so-called DMOADS—that not only relieve symptoms but also slow the disease down or actually reverse the disease process. Some of the agents described as possibly having disease-modification potential include glucosamine, chondroitin sulfate, intra-articular hyaluronans, diacerein, avocado/soybean unsaponifiables, and doxycycline among others.17 Further studies will help to define the purported role of such agents in disease modification.
DR. BLOCK: I think it’s fair to say that, as of today, there really are no strategies that have been proven to be effective at retarding the progression and pain of OA over long periods of time. I think that is the gold standard that we’re looking for, and there is suggestive evidence from studies performed on each of the agents that Dr. Moskowitz just mentioned and several others.
I think there is a lot of work being done to study various metalloproteinase inhibitors, especially the collagenase 3 (MMP-13) inhibitors, and the aggrecanase inhibitors. I think that if some of these things are demonstrated to be effective in delaying the progression of OA, they could be extremely exciting, but one needs to keep in mind that whatever we use as a DMOAD has to be extremely safe because it’s going to be used for decades in people who are basically asymptomatic. In order to justify that on a public health basis, it has to be extraordinarily safe. It’s a very high bar.
DR. GALL: Okay. Dr. Block, can you now attempt to discuss cartilage regeneration and the use of the stem cell?
DR. BLOCK: Yes. Mesenchymal stem cell technology is extremely exciting, and it has paid off in some areas of bone and other connective tissues. As everybody knows, there is one U.S. Food and Drug Administration-approved approach for replacing cartilage that has had some success, but it’s used for isolated chondral defects in young and otherwise healthy people—not for OA.
The problem, of course, is that as we understand OA better and better, it’s more than just cartilage degeneration, and more importantly, the cartilage, which is very important, is a very thin and delicate tissue. If we replace the cartilage alone without normalizing the aberrant biomechanics across the joint—without normalizing the subchondral bone that the cartilage sits on—we have very little chance of getting long-term relief.
Having said that, efforts are being carried out in a variety of laboratories around the world to focus on not only mesenchymal cell-directed cartilage formation but also on actual repair of most tissues of the joint. Once we understand how to grow new cartilage and actually have it integrate with the adjacent tissue, which we still are not able to do, and once we’re able to repair some of the subchondral bone, I think that there is a lot of promise for that strategy in the long run. But, in the short-term, again, it’s a very difficult process that is not yet well understood.
DR. MOSKOWITZ: Well said. I agree. I think that we’re on the brink of being able to repair, particularly, very focal defects—maybe 4- or 5-mm defects. But, to repair the joint, as Dr. Block pointed out, you can’t just repair the cartilage because joint changes such as inflammation, meniscal alterations, varus and valgus deformities, and other changes impacting the joint are going to impair cell-based regeneration. Until we get those impacts controlled, I think it’s going to be some time before we can say to someone, “We’re going to replace your cartilage and normalize your joint.” However, I am optimistic and think that down the line, we may be able to do it.
DR. GALL: Dr. Block also mentioned that the underlying bone has changed too, and so, that needs to be attacked as well in these approaches.
DR. BLOCK: My personal view is that in the short-term future—the next 5 to 10 years—big strides will be made in strategies for better pain relief, and there are a variety of biologics that are in phase II and phase III testing that already look very exciting. Again, my own personal research interest is in trying to normalize the mechanical loads across the joints so that we can protect the joints better and so that the OA won’t progress, and I think those kinds of strategies will be available over the next couple of years.
DR. GALL: I’d like to thank you both for a really enlightening and comprehensive discussion of this common disease. Just to review, we’ve discussed what OA is and defined it, talked about its burden and its diagnosis, and mentioned the various risk factors for OA, particularly in light of what we can do to prevent OA or prevent the progression of the disease. We also had a comprehensive talk about the treatment of OA from both the standpoint of pain and the actual disease, and we touched upon the future of this as well as the research that’s being done in these areas.
I really appreciate your wisdom and discussion, and I think we’re providing the primary care physicians and providers with a really comprehensive look at this disease.

DR. BLOCK: Throughout the 20th century, we always considered OA to be primarily a degenerative disease of cartilage, but during the past decade or more, 2 things have become apparent: First, from a clinical perspective, OA is not just a structural degenerative process, it is primarily a very painful disease with pain being its most prominent feature. Second, the degenerative process involves not only the cartilage but the entire joint and all the involved structures within it.
A reasonable working definition of OA right now would be a painful degenerative process involving all the joint structures and is not primarily inflammatory but involves progressive deterioration of joint structures including articular cartilage. It’s important to keep in mind that pain itself is critical because as individuals age, everybody has some degenerative processes in their joints, and if we look hard enough, we can find the pathological features of OA in all elderly people. However, not all elderly people actually have the clinical disease.
DR. GALL: In a moment, we’ll talk about the causes of this, but, Dr. Moskowitz, would you tell us what the burden of this disease is here in the United States and worldwide?
DR. MOSKOWITZ: Well, it’s the most common form of arthritis and affects nearly 27 million or more Americans.1 It’s the most common disabling disease of the rheumatologic group, and it’s very disabling among all diseases.
DR. GALL: In the United States, you say that there’s about—
DR. MOSKOWITZ: About 27 million people with OA. And, in a decade, it is anticipated that the number will significantly increase.
DR. GALL: How many of those people are affected to the point that they’re unable to do their normal activities of daily living (ADLs)?
DR. MOSKOWITZ: Well, in terms of disability, about 80% of patients with OA have some degree of movement limitation, 25% cannot perform major ADLs, 11% of adults with knee OA need help with personal care, and 14% require help with routine needs.2
DR. GALL: Dr. Block, you talked about pain as a major manifestation of this disease. Does everybody who has OA present with pain?
DR. BLOCK: Again, it’s a definitional question; there is a distinction between clinically evident OA and asymptomatic structural degeneration of the joint. The population that Dr. Moskowitz was just describing, which comprises 20 to 30 million people, has doctor-diagnosed symptomatic OA, which is a painful disease. A much higher number of people who have structural degenerative disease would be diagnosed by radiography and said to fulfill a radiographic definition of OA, but all of the people who Dr. Moskowitz refer to have pain.
DR. MOSKOWITZ: Pain is what brings a patient to the doctor. I’ll often ask my patients, “How are you doing and what can I do for you?” They have limited motion and can’t get around. They say, “Dr. Moskowitz, I just want to get rid of the pain. I’ll worry about the swelling and getting around later.” And, that’s what really motivates them to get medical attention.
DR. GALL: Often, we will get consultations from primary care physicians for a patient who has OA that’s been picked up by radiography, and the patients will come and really not complain of pain in that area or possibly might have another underlying disease that’s causing the pain that’s not related to the OA. Dr. Block, do you want to say a word about that?
DR. BLOCK: Sure. By the age of 80 years, essentially, 100% of the population will have evidence of radiographic OA in at least one of their large joints. If you start with that number and you’re then referred an elderly patient merely for the radiographic appearance of OA, that doesn’t tell you very much about what’s going on clinically, and so, most of us would not even describe that as a clinical disease.
They may have a degenerative process in their knee, hip, etc, but of that group, say at the age of 80 years where almost 100% of people will have radiographic evidence of OA, only about 15% to 20% have symptomatic disease.3 That’s the culprit that I think we’re talking about clinically—people who not only have degenerative structural disease but also have symptoms that are interfering with their quality of life or their daily activities.
DR. MOSKOWITZ: I think that’s an important point, Dr. Block. For example, we all see patients who come in complaining of hip pain and you examine their knees as well and they have terrible genu varum (bowleg) and you say, “Do your knees bother you?” and they say, “Doctor, my knees are fine.” You think, my goodness, how can you walk? It isn’t necessarily true that if you have a deformity or involvement of a joint that you’re going to have pain, but if you have painful joints, that brings you to the doctor.
DR. GALL: Dr. Block, once again, I would like you to summarize the etiology of OA. Obviously, there has been much research and much information that has come to light in recent years regarding the causes of this disease.
DR. BLOCK: As I said, throughout the 20th century, people interested in the pathophysiology of OA were quite convinced that it was a degenerative process of the articular cartilage. As people age, the articular cartilage starts degenerating, and when there is absence of intact cartilage that ought to be providing essentially frictionless articulation of the bones during motion, there is deterioration, and that’s what we always considered to be OA.
Of course, the missing link in that paradigm is that cartilage itself has no nerve or blood supply and is therefore painless, and yet, people have horrible pain with this disease. So, our understanding over the past 10 or 15 years has really dramatically progressed, and we have begun to appreciate both degenerative and reactive processes in the subchondral bone, the ligaments, and the muscle.
The way we look at the pathophysiology of the onset and progression of the disease today is that there is primarily a degenerative process that stimulates reactive processes throughout the joint and even in the immune and inflammatory pathways. So, the reaction to that degenerative process sometimes causes stimulation of nociceptors and a lot of pain because of either local inflammation or mechanical alterations.
The degeneration itself, as I said, is painless. Often, people can have very degenerative joints, as Dr. Moskowitz just mentioned, and have no pain and therefore no clinical symptoms, so the disease is a combination of the degeneration and the secondary stimulated pain.
DR. GALL: So, is this primarily a biochemical or a cellular disease? Is it a genetic disease?
DR. BLOCK: Yes to all.
DR. MOSKOWITZ: There are a number of factors, Dr. Gall, involved in this condition. First, for example, is aging. We see that the frequency of OA increases logarithmically as we age, and there are pathologic changes with age that appear to lead to OA. For example, pigmented collections in the joint, comprising advanced glycation end products, occur that may predispose a patient to OA. You’re going to find more OA in an aging population.
The second factor is trauma. Professional football and basketball players, for example, who have chronic trauma, meniscal injuries, or cruciate ligament injuries are predisposed to OA. Third—the big risk factor, of course—is being overweight or obese. Patients who are overweight have a much higher frequency of OA, particularly in the knees. Last, there are genetic factors. For example, OA in the hands, which is more often seen in women, is genetically oriented so that if your mother had it or your aunt had it, you’re more likely to get it. Accordingly, there are multifactorial etiological factors that we have to try to address.
DR. GALL: Can you say a word about the different areas of the body that are associated with OA and talk a little bit about the difference between OA of the hands that we see frequently in women in relation to OA of the knee, hips, and spine, which can be devastating for individuals?
DR. MOSKOWITZ: Any joint can have it. It can be in the ankle, for example, if there has been trauma, but we’re looking particularly at the knees, the hips, the hands, and the spine. It’s interesting—certain joints in the hands are predisposed to OA including the distal and proximal interphalangeal joints. It tends not to involve the metacarpophalangeal joints, although it can in severe cases. Of course, the first carpometacarpal joint is frequently involved, and OA in this joint can be very disabling.
I have patients, for example, who are pianists or people who use their hands in their daily occupation. Their problem is often unfortunately minimized, with the doctor saying, “Oh, you’ve got a touch of OA, you can live okay with it.” However, this is hard to do because of pain and decreased function—OA can be a very disabling disease. In a number of women, the joints of the hands can be very inflamed. There’s a form of hand OA called erosive inflammatory OA, which can be especially troublesome because it’s very destructive. It’s almost like a low-grade rheumatoid arthritis where you actually get a lot of joint breakdown and deformity—it can be very disabling. OA of the knees or hips obviously can be a problem because of difficulties with ambulation.
DR. BLOCK: Our medical model trains us that, in general, we should look for an abnormality on a laboratory test to make a diagnosis. We do look for radiographic evidence of OA because, as I have said several times already, almost every elderly patient will have radiographic evidence of OA-like degeneration; however, we primarily use radiography adjunctively to make sure nothing else is going on or to assess the severity of the degeneration.
We make a diagnosis purely clinically. We look for someone who has the appropriate degree of pain in specific joints and does not have evidence of a systemic inflammatory source of that pain or a systemic rheumatic disease and in whom the pain appears to be articular rather than extra-articular. Of course, clinically, we feel for crepitus when we move the joint because of the degenerative processes, and we feel for bony enlargements or osteophytes around the joint to assist in making the diagnosis of OA.
Radiography is helpful in the sense that it can tell us about the severity of the degeneration and help us to make sure that we’re not missing something else such as a malignancy; however, radiography itself is not critical for the clinical diagnosis of OA.
DR. GALL: Dr. Block, how can the clinician who first sees a patient with OA differentiate it from a common type of inflammatory arthritis such as rheumatoid arthritis?
DR. MOSKOWITZ: If I may comment on that; you’re looking at 2 things. First, you are looking for symptoms and signs that you expect to be associated with OA, and then, you are looking for signs and symptoms that are not consistent with OA. As we said earlier, you may get some inflammation in the knee. You may get some swelling, and you can have evidence of increased synovial fluid, but you wouldn’t have the diffuse inflammatory reaction that you would have in rheumatoid arthritis, and there are different joints involved. For example, in rheumatoid arthritis, there may be involvement of the proximal interphalangeal and metacarpophalangeal joints of the hands, wrists, elbows, or shoulders. You would have involvement of peripheral joints that are different from those that are characteristically involved with OA.
In OA, the patient doesn’t have systemic findings such as fever, weight loss, or generalized prolonged stiffness. The patient often has localized stiffness in the involved joint but not generalized stiffness like that seen in rheumatoid arthritis. In OA, you can have multiple joints involved, such as 2 knees and 1 hip, but involvement doesn’t come on all at once and with the same severity.
DR. BLOCK: I completely agree with everything Dr. Moskowitz said. Additionally, if one is still confused after all of the clinical signs, this is where radiography may be useful because the radiographic appearance of OA is really different from that of the inflammatory arthritides.
In OA, one expects asymmetric narrowing in the joint itself. Additionally, OA results in subchondral sclerosis instead of periarticular osteopenia, which is seen in inflammatory arthritis. Finally, often, in OA, there is osteophyte formation, which is in contrast to the erosions that may be seen in the inflammatory arthritides. This is one area where radiography can really help.
DR. MOSKOWITZ: You have to be careful with respect to diagnosis in older people because if you do a serum rheumatoid factor study, the rheumatoid factor may be positive, but this may be unrelated to the patient’s symptoms. Studies have shown that a positive rheumatoid factor may be nonspecifically related to aging. So, you have to be careful—this finding can be a red herring in the diagnosis.
DR. BLOCK: I agree completely, and because OA is so common, one needs to bear in mind that a patient might have both inflammatory arthritis and underlying OA at the same time.
DR. MOSKOWITZ: Great point. We all see patients who come in to the office with OA of the hands, and then they develop rheumatoid arthritis or lupus engrafted on that previous involvement.
DR. GALL: I’d like to move on now to the management of the disease and, Dr. Moskowitz, would you talk to us about the first approach, which would be prevention? This is an approach that has caught the attention of the Centers for Disease Control and the Arthritis Foundation, and there is a major ongoing campaign at this time about what we can do to prevent this disease. Could you summarize that for us, Dr. Moskowitz?
DR. MOSKOWITZ: Absolutely. It’s generally thought that there’s nothing you can do to prevent OA. Well, we now think that you can slow it down and perhaps prevent it. Number one, we talked about weight. If a patient were to lose just 10 or 12 pounds, that could have a significant impact on the destructive effect of weight on the progression or the development of the disease. Programmed exercise is also very important. People say, “Well, I have arthritis. I can’t exercise,” and this is a problem because if you’re overweight and you have OA of the knees, joint overuse may temporarily lead to more symptoms. But walking at a reasonable pace and duration can be helpful with respect to symptoms and disability—the body puts out pain-relieving endorphins, muscles are strengthened, and joint range-of-motion is improved. Walking on a treadmill at a reasonable pace helps to achieve weight loss.
The patient can walk on a prescribed basis according to his or her capabilities. It’s important not to ask the patient to do something you know they’re not going to be able to do. We wouldn’t ask them to lose 20 pounds in the next 2 months. We have to make the program practical—these things are not easy to do, so we’ve got to be very supportive.
While trying to prevent disease progression, you want to have the patient strengthen their joint-related muscles. You want them to do muscle-building exercises because if you have joint stability, you’re likely going to decrease the osteoarthritic process as well. Losing weight is very important. Exercise is important. Using hot and cold applications for local therapy, which is safer than medication, is helpful.
Importantly, you don’t want to limit the patient’s activities any more than necessary. The way that I’ve always practiced medicine is that you don’t want to take away the patient’s ability to live his or her life as normally as possible. You don’t want to prescribe “don’ts,” like “don’t walk” and “don’t climb steps.” You want the patient to walk and do exercises, but the exercises have to be programmed so that the patient is able to do them.
DR. GALL: This is actually a very common question that primary care physicians are faced with when a patient with this disease comes in and is afraid to exercise and has a difficult time losing weight. But, I think it’s important that we understand that the cartilage gets its nourishment by being compressed and released and it has no blood supply of its own, so a lack of exercise is going to further cartilage degeneration.
DR. MOSKOWITZ: There are other non-weight bearing activities such as aquatic exercises that most people can do. You don’t have to be able to swim. You can do water exercises where you have the buoyancy of the water allowing for passive assistive exercise.
DR. BLOCK: Let me just add one other thing to the exercise discussion. In addition to there being a structural benefit to controlled exercise, every single systematic evaluation that has been performed has demonstrated that there is a really substantial and sustained pain relief component to exercise. People who have OA who are able to exercise regularly get substantial pain relief just from the exercise, and this is really important because the pain is what’s slowing them down in the first place.
The problem, of course, is maintaining an exercise regimen for a long term. Remember, this is a disease of decades, and we are not that good at behavioral modification strategies. Patients often give up on the exercise after a while. But, if you can maintain it, there are structural benefits as well as really substantial pain relief benefits.
DR. MOSKOWITZ: Yes, I agree. The other thing is that it’s hard for the busy physician in the office to start teaching the patient how to exercise, so we need to use arthritis health professionals such as occupational therapists and physical therapists to create exercise programs and teach patients how to exercise more effectively.
DR. BLOCK: Can I add one more thing as long as we’re discussing prevention? One of the major societal risk factors right now is recreational trauma. We have a population of young individuals who are being brought up in various organized sports, and there’s a very substantial risk factor for adolescent and young women who are, for example, playing soccer. They are getting knee and anterior cruciate ligament injuries, and over the upcoming 10 to 15 years, these people are at an enormous risk for developing knee OA. So, we need to develop some strategies to reduce the recreational trauma that results in early OA in this population.
DR. GALL: So, now we realize that weight control and exercise are important. Can we now talk about the medical management of both the pain and the arthritis?
DR. MOSKOWITZ: I know we don’t want to take too much time with this, but before we finish, I wanted to mention that I keep getting asked about tai chi or acupuncture for treatment. There are data suggesting that these programs can be helpful, but they should be adjunctive considerations for patients not responding to more routine therapeutic programs.4
DR. GALL: Yes, I would certainly agree with that. These are adjunctive therapies that may be helpful in select patients, but we need to focus on the more proven aspects of the prevention of the disease. Let’s now divide our talk about treatment into pain management and disease management. Can we start with pain management?
DR. BLOCK: I think that, first of all, it’s really important not to neglect the adjunctive measures that we’ve already discussed, and so, pain management is multifactorial, but one needs to include a physical and occupational therapist because although regular exercise dramatically reduces pain, local measures such as heat or ice are often very useful.
When they don’t get sufficient relief from adjunctive measures, symptomatic patients with OA will need to move to the pharmacologic arena sooner or later. From my practice and from the literature, I would say that there are 2 kinds of pain that need to be treated in OA: Pain that occurs during a painful flare that may last a couple of weeks and chronic ongoing pain that may develop as the disease progresses.
During short painful flares, most of the organizations that have published guidelines over the years have suggested that acetaminophen is a good place to start.5,6 I think that the systematic literature at this point suggests that acetaminophen might be very good for short-term pain relief—meaning, a few weeks at most. It’s probably not very effective for long-term pain relief, and it has a fair amount of potential complications, especially in the elderly. I don’t tend to use a lot of acetaminophen in people who are having chronic pain from OA, but during short-term pain flares, it can be very useful.
One can choose various analgesics including topical nonsteroidal agents, which can be very effective for local and monoarticular pain, for example, pain in superficial joints such as the knees or fingers. However, sooner or later, I believe that if patients don’t have a contraindication, they will end up taking either nonsteroidal anti-inflammatory agents (NSAIDs) or COX-2 inhibitors (coxibs), and that’s probably for a good reason. The nonsteroidals and coxibs have been demonstrated repeatedly to retain pain relief during 2-year studies, and they’re almost unique among the pharmacologic agents in that they retain that pain relief over a couple of years.7,8
Of course, if people are undergoing adequate pharmacologic therapy and they have painful flares in single joints, then intra-articular therapies such as glucocorticoids or hyaluronans are often very effective.
DR. GALL: I’d like to just go back to the NSAIDs for a moment. There is increasing emphasis on the risk of NSAIDs, particularly in the elderly. How do we balance the benefits of NSAID use for chronic therapy versus the risks, and how would you monitor the patient?
DR. MOSKOWITZ: Well, I agree with the premises that Dr. Block mentioned. I think acetaminophen has varying efficacy, but I think it’s worth trying. If I am right, I think it was stated in the past that the acetaminophen dose could go up to 4 g/d.9 The current recommendation is that doses of acetaminophen should not exceed 3 g/d so as not to incur hepatic or renal toxicity. The problem is that acetaminophen is often present in other medicines that patients are taking, and so an excess total intake is not uncommon.10
I think a trial of acetaminophen is worthwhile because even if it doesn’t relieve all the pain, it’s a floor of analgesia that you can add to with nonsteroidals.
With regard to the question about whether nonsteroidals are dangerous in older people, I think that they can be. Most things we use are unfortunately associated with some risk, although pain itself is also a risk factor. Pain increases blood pressure and pulse rate. If you relieve the pain, you’re probably relieving more of the stress on the patient overall as opposed to the risk of the NSAID itself. If you use nonselective NSAIDs, I would suggest adding a proton pump inhibitor, especially if the patient has an increased risk of peptic ulcer disease. If you use a COX-2 selective inhibitor, data suggest there is a decreased gastrointestinal (GI) risk. Overall, I think that NSAIDs can be effective and reasonably safe. I’m more careful about using NSAIDs in individuals older than 75 or 80 years; however, many of these patients are physiologically younger than their numerical age, and they can more safely tolerate these agents.
Intra-articular steroids and intra-articular hyaluronans can be very helpful in the management of knee OA, and they have comfortable safety factors.
DR. GALL: I’ll just make a comment about my own approach to that. When I put a patient on an NSAID, and I do use them frequently, I mark it on a problem list. I’m careful to ask the patients about bleeding and to warn them about the signs of GI bleeding, and I do periodic blood counts to look at hemoglobin and creatinine levels. I also do a urinalysis to rule out silent GI or renal effects of these drugs, but I do use NSAIDs frequently.
Additionally, with the recent attention to the pain component of OA over the past decade, there has been a lot of systematic investigation into various neuroactive pain-directed medications. In fact, duloxetine, which is a neuroactive agent, was approved for use a couple of years ago. There are non–anti-inflammatory, non-purely analgesic medicines that can be very helpful for the treatment of the pain component of OA.
DR. GALL: Thank you. Could we just say a word about opioids and tramadol as adjunctive therapies and what the pluses and minuses of using these drugs are?
DR. MOSKOWITZ: I think there is not only a rationale but a place for these agents in treating OA, but we’ve got to be careful. I’m a little less concerned about using tramadol than using the classic opioids, per se, and I think tramadol can be a reasonable bridge when people are not responding to NSAIDS. A number of years ago, when I was writing a piece for the Arthritis Foundation pamphlet, I stated that there is never a place for opioids in the treatment of OA, and I can’t tell you how many of my colleagues wrote and said, “Dr. Moskowitz, there are times when we feel they need to be available.” I agree, but I think my guidance is that, if you use an opioid, use the lowest dose possible and for the shortest time possible.
I think if someone is in a lot of pain and they’re having a flare, particularly an older individual, it may be safer to use the opioids than to put them on NSAIDs, particularly if they have had past trouble with NSAIDS. I don’t think that we should never use opioids when treating OA. What are your thoughts on that, Dr. Block?
DR. BLOCK: I agree. I think that there is good evidence that the opiates provide really substantial pain relief, so they’re effective in OA. The problem, of course, is that they have very high side effect profiles, and the people that they’re the most dangerous for with regard to falling and injuring oneself are actually the same people who are at high risk with nonsteroidals—the very elderly with congestive heart failure. It really does put us in a bind.
I think that I agree with what you just said, which is that they are effective, and at times, I think that there is clearly a place for opiates in OA, but one needs to be judicious and careful when using them. Tramadol is, I think, much safer. It’s a weak opiate. On the other hand, it also has much less pain-relieving potential, so this is the bind we face.
Well, I think what we haven’t mentioned yet are the surgical approaches, which are critically important.
DR. MOSKOWITZ: Should we discuss glucosamine and chondroitin sulfate?
DR. BLOCK: So, more than half of patients who have symptomatic OA use various complementary medicine approaches. They are widely used because they’re widely believed to be beneficial, and I think that there has been a fair amount of systematic evaluation, specifically of glucosamine and chondroitin sulfate, over the past several years.
When we look at the independently sponsored studies, the evidence suggests that the side effect profile for both agents is very good. As long as they were manufactured in a safe manner, they are very safe and one shouldn’t worry about using them.
On the other hand, the efficacy above placebo is very low, but that doesn’t mean that they’re not effective in individual patients. The thing that’s really important to note here is that whenever there is a placebo-controlled study with pain as an outcome in OA, the placebo response is huge. More than half of the people who get placebo get very substantial clinically significant pain relief, and more importantly, it’s durable. In all of these placebo-controlled studies that go on for 2 years, the placebo group with pain relief had sustainability over 2 years,11,12 and so, if one gets more than a placebo response from glucosamine, and if it’s providing pain relief, I’m happy for them to use it.
The Glucosamine/Chondroitin Arthritis Intervention Trial (GAIT),7 the large National Institutes of Health multicenter study, which was a null study, showed that fundamentally, there was no systematic advantage of a combination glucosamine plus chondroitin sulfate. Even when that came out as a null study and was publicized as such, the market for glucosamine and chondroitin sulfate in the following year didn’t decrease in the United States.13,14
People who are getting a benefit, whether it’s due to an endorphin effect from placebo or the agent, are going to continue using the agent. As long as the agents are safe, I’m comfortable with my patients using them if they really are feeling like they are getting relief.
DR. MOSKOWITZ: Yes, I think that there are conflicting data, but there are a number of studies that seem to show that these agents do help some people. For example, this question about the GAIT study7 not showing an effect, if you’re using glucosamine and chondroitin sulfate in individuals who have high pain to start with—if they had a score of more than 300 mm on the Western Ontario and McMaster Universities Arthritis Index (WOMAC)—they appeared to do better, but there wasn’t a predefined endpoint, so the result has to be substantiated in a repeat study. However, I see enough people—like you do, Dr. Block—who seem to respond. They’re safe agents, and I think that they do have merit in patients who are not getting a benefit from other agents.
DR. GALL: Before we move on to surgery and the future of therapy, I just want to discuss intra-articular steroids. What are your thoughts on these?
DR. MOSKOWITZ: I would be lost without them. I remember when they were first used by Dr. Joseph Hollander in Philadelphia, and they failed to help because he used cortisone acetate instead of the hydrocortisone derivative, and cortisone has to be converted to hydrocortisone before it works.15 I use intra-articular corticosteroids a lot. The general recommendation is that you shouldn’t use it more than 4 times a year in the knee. I think maybe if somebody is older—for example, 88 years—and they cannot tolerate other therapy, you might use them that often. Studies have shown that an intra-articular corticosteroid injection every 3 months did not lead to deleterious anatomic effects.16 I think using them 2 or 3 times a year, if indicated, can be symptomatically effective and safe, and I don’t think that will lead to joint breakdown if the patient is careful about doing their exercises and other management.
DR. GALL: Let’s move on to the use of surgery, and without going into all the surgical procedures, when is it appropriate for the clinician and the patient to consider surgical intervention in OA?
DR. BLOCK: It is entirely patient-oriented. You can’t tell by structure or by X-ray. When the patient’s OA is painful and severe enough, when it cannot be controlled with medication and medical regimens, or when it’s interfering with their lifestyle and they can’t live with it, they’ll tell you they need surgery.
DR. MOSKOWITZ: I completely agree. I think you can’t tell them. They’ll let you know. They’ll say, “I just have so much pain and disability. I need something done.”
DR. GALL: I think it’s important also to bring the surgeon in, not as a plumber to fix something, but as a partner in making the decision. Certainly the primary care physician, often the rheumatologist, can also provide guidance and work with the patients and the surgeons in making that decision.
DR. MOSKOWITZ: Yes. Let me just add one thing: I don’t think the patient should be in an extreme state of pain and disability in order to have surgery. If the condition interferes with their ADLs and the pain is really encumbering their daily activities, then it’s not unreasonable to consider surgery. I don’t think they have to be so bad that they’re limping and in terrible distress.
DR. BLOCK: Having said that, we should mention that joint replacement, at least in the knees and the hips, is extraordinarily effective in relieving pain.
DR. GALL: Yes. I would agree and these advances have continued to increase over the years, and these replacements last for a longer period of time, so the amount of satisfaction has increased, and the number of complications in experienced centers has certainly decreased.
Let’s end by talking about the future of OA. There are 2 areas that I’d like to touch on: One is the disease-modifying OA drugs (DMOADs) and the other is cartilage regeneration with stem cells and other techniques. Dr. Moskowitz, maybe you can talk about the DMOADs, and Dr. Block, you can talk about cartilage regeneration.
DR. MOSKOWITZ: Disease retardation or reversal would be the holy grail of OA management: to be able to treat OA with medications—the so-called DMOADS—that not only relieve symptoms but also slow the disease down or actually reverse the disease process. Some of the agents described as possibly having disease-modification potential include glucosamine, chondroitin sulfate, intra-articular hyaluronans, diacerein, avocado/soybean unsaponifiables, and doxycycline among others.17 Further studies will help to define the purported role of such agents in disease modification.
DR. BLOCK: I think it’s fair to say that, as of today, there really are no strategies that have been proven to be effective at retarding the progression and pain of OA over long periods of time. I think that is the gold standard that we’re looking for, and there is suggestive evidence from studies performed on each of the agents that Dr. Moskowitz just mentioned and several others.
I think there is a lot of work being done to study various metalloproteinase inhibitors, especially the collagenase 3 (MMP-13) inhibitors, and the aggrecanase inhibitors. I think that if some of these things are demonstrated to be effective in delaying the progression of OA, they could be extremely exciting, but one needs to keep in mind that whatever we use as a DMOAD has to be extremely safe because it’s going to be used for decades in people who are basically asymptomatic. In order to justify that on a public health basis, it has to be extraordinarily safe. It’s a very high bar.
DR. GALL: Okay. Dr. Block, can you now attempt to discuss cartilage regeneration and the use of the stem cell?
DR. BLOCK: Yes. Mesenchymal stem cell technology is extremely exciting, and it has paid off in some areas of bone and other connective tissues. As everybody knows, there is one U.S. Food and Drug Administration-approved approach for replacing cartilage that has had some success, but it’s used for isolated chondral defects in young and otherwise healthy people—not for OA.
The problem, of course, is that as we understand OA better and better, it’s more than just cartilage degeneration, and more importantly, the cartilage, which is very important, is a very thin and delicate tissue. If we replace the cartilage alone without normalizing the aberrant biomechanics across the joint—without normalizing the subchondral bone that the cartilage sits on—we have very little chance of getting long-term relief.
Having said that, efforts are being carried out in a variety of laboratories around the world to focus on not only mesenchymal cell-directed cartilage formation but also on actual repair of most tissues of the joint. Once we understand how to grow new cartilage and actually have it integrate with the adjacent tissue, which we still are not able to do, and once we’re able to repair some of the subchondral bone, I think that there is a lot of promise for that strategy in the long run. But, in the short-term, again, it’s a very difficult process that is not yet well understood.
DR. MOSKOWITZ: Well said. I agree. I think that we’re on the brink of being able to repair, particularly, very focal defects—maybe 4- or 5-mm defects. But, to repair the joint, as Dr. Block pointed out, you can’t just repair the cartilage because joint changes such as inflammation, meniscal alterations, varus and valgus deformities, and other changes impacting the joint are going to impair cell-based regeneration. Until we get those impacts controlled, I think it’s going to be some time before we can say to someone, “We’re going to replace your cartilage and normalize your joint.” However, I am optimistic and think that down the line, we may be able to do it.
DR. GALL: Dr. Block also mentioned that the underlying bone has changed too, and so, that needs to be attacked as well in these approaches.
DR. BLOCK: My personal view is that in the short-term future—the next 5 to 10 years—big strides will be made in strategies for better pain relief, and there are a variety of biologics that are in phase II and phase III testing that already look very exciting. Again, my own personal research interest is in trying to normalize the mechanical loads across the joints so that we can protect the joints better and so that the OA won’t progress, and I think those kinds of strategies will be available over the next couple of years.
DR. GALL: I’d like to thank you both for a really enlightening and comprehensive discussion of this common disease. Just to review, we’ve discussed what OA is and defined it, talked about its burden and its diagnosis, and mentioned the various risk factors for OA, particularly in light of what we can do to prevent OA or prevent the progression of the disease. We also had a comprehensive talk about the treatment of OA from both the standpoint of pain and the actual disease, and we touched upon the future of this as well as the research that’s being done in these areas.
I really appreciate your wisdom and discussion, and I think we’re providing the primary care physicians and providers with a really comprehensive look at this disease.

The Medical Roundtable: Chronic Low Back Pain
Michael Kurisu is at the University of California San Diego Health System where he’s a faculty member in the Department of Family Medicine. He also teaches at a number of osteopathic medical schools across the country, has a particular interest in osteopathic manual therapy as well as prevention of musculoskeletal injury, and works closely with our colleagues in physical therapy. Hollis King, DO and PhD, is a fellow of the American Academy of Osteopathy, Program Director of Osteopathic Residency Education, and Professor in the Department of Family Medicine at the University of Wisconsin School of Medicine and Public Health. Howard Schubiner is the Director of the Mind-Body Medicine Center in the Department of Internal Medicine at Providence Hospital in Southfield, Michigan, and is a Clinical Professor at Wayne State University.
Chronic back pain is among the most common patient complaints. Its prevalence and impact have spawned a rapidly expanding range of tests and treatments. Some of these have become widely used for indications that are not well validated, leading to uncertainty about efficacy and safety, increasing complication rates, and marketing abuses. Recent studies document a 629% increase in Medicare expenditures for epidural steroid injections, a 423% increase in expenditures for opioids for back pain, a 307% increase in the number of lumbar magnetic resonance images among Medicare beneficiaries, and a 220% increase in spinal fusion surgery rates. The limited studies available suggest that these increases have not been accompanied by population-level improvements in patient outcomes or disability rates. We suggest a need for a better understanding of the basic science of pain mechanisms, more rigorous and independent trials of many treatments, a stronger regulatory stance toward approval and postmarketing surveillance of new drugs and devices for chronic pain, and a chronic disease model for managing chronic back pain.1
Despite this increase in investment, we have not seen a significant reduction in morbidity of low back pain.1
When we refer to integrative medicine, what we’re actually talking about is combining the therapies that work best to understand how humans heal within complex systems. Low back pain is a perfect example of how complexity based on biopsychosocial-spiritual influences can influence the severity of pain as well as suffering.
The Centers for Disease Control and Prevention National Health statistics report2 showed that low back pain was, by far, the most common condition for which patients seek complementary and alternative medicine care. We hope to eliminate these terms and refer to them instead as just good medicine, where the research guides us toward what works best. With this goal in mind, the National Institute of Clinical Excellence in England released their guidelines for low back pain that were published in the British Medical Journal.3 They summarized those therapies that had the best evidence for yielding beneficial effects.
The therapies that had the most benefit with the least potential for harm were physical therapy but not traction, exercise, mind/body influences including psychology, acupuncture, and surgery when indicated, particularly for severe radicular pain. That’s almost a different diagnosis when you have severe radicular pain. We will focus more on low back pain and chronic low back pain, without significant radicular symptoms. The guidelines also supported nonsteroidal anti-inflammatory drugs.
Two things that the guidelines did not support in this evidence-based review were epidural steroids and opioids. We use opioids a lot, but the research shows that maybe we shouldn’t do so. The Danish health and morbidity study4 of more than 10 000 patients who were treated with opioids for noncancer pain showed that the patients did not meet any of the 3 outcome measures associated with pain management. Surprisingly, opioids did not result in improved function, improved quality of life, or a reduction in pain.
When we talk about how to deal with these different aspects of pain, we’d like to use the expertise of our panel to focus on 3 main therapeutic areas. We will use a 3-legged stool model to highlight each of these 3 therapeutic areas. The first leg is the external or physical parts of low back pain, including structure and mechanics. The second leg is the internal or emotional aspect, ie, the importance of stress and emotions on why that pain might be persisting. The third leg of the stool is reconditioning. How can we get the body to be strong and supportive? How can we work with our colleagues to create these interdisciplinary teams to yield better outcomes, particularly as accountable care organizations become more popular with regard to improving outcome measures for low back pain? What professionals would we want to work with for the best outcome?
Dr. King, I’d like to start with you. You could talk about exploring the external and the physical piece. You have particular expertise in osteopathic manual therapy as well as research in this area. Would you mind sharing some of your insights with regard to manual therapy and the treatment of this condition?
DR. KING: In the present medical research context of needing to have your work be well justified by evidence-based medicine research, all the professions who use their hands in health care have been striving to generate acceptable research. At present, the chiropractic profession is probably the one that has produced the most practical research on spinal manipulation. The osteopathic profession has followed suit pretty well too. That’s where I have personally been involved in the research.
For instance, with chronic low back pain, this is one of the subjects where we actually have state-of-the-art evidence-based research. A systematic review and meta-analysis that was conducted by Licciardone et al and published in 2005,5 which is a Cochrane review level of evidence, describes all the necessary meta-analysis aspects indicating that osteopathic manipulative treatment (OMT) significantly reduces low back pain. From the osteopathic perspective, OMT is delivered to patients with the diagnoses of somatic dysfunction or malalignment of the vertebral column, as well as malalignment of the appendicular skeleton for upper and lower extremities. In this case, we’re talking about the low back.
We now have state-of-the-art evidence of the benefit of OMT for low back pain. This evidence has been established in practice guidelines published by the Agency for Healthcare Research and Quality.6 These guidelines indicate where OMT should be utilized in the treatment of chronic low back pain. This is in the context of conventional medical treatment of chronic low back pain, where essentially the guidelines say that OMT should be used. The administration of OMT typically occurs as a part of an outpatient visit, for either musculoskeletal pain or even for a sore throat, or the physician may have a day in his clinic schedule when all that is done is OMT—an OMT clinic if you will; this is my style of doing OMT. For a sore throat, OMT can quickly be done to enhance lymphatic drainage and augment the healing process and even help any prescribed medication get to the infected area through improved circulation.
We have reached this level of medical research. The outcome is that, in my experience at least, there is very little resistance on the part of third-party carriers including Medicare to reimburse people for the delivery of OMT wherein the diagnosis is low back pain and particularly, chronic low back pain. This has been very helpful because the reimbursement element is critical in order to provide this service.
There are several other research initiatives, one of which was undertaken by Licciardone et al,7 in which OMT for 488 subjects was compared for chronic low back pain by using ultrasound. I was a treatment provider in that study, the results of which support the meta-analysis discussed above. The first publication derived from this study reports a subgroup analysis that assesses cytokine production after OMT. The results were that the cytokine interleukin 6 was correlated with back pain severity.8
From the research side, we are gradually—certainly between the osteopathic and the chiropractic professions—generating the evidence that spinal manipulation, the hands-on work, is of definite benefit in the care of patients who have been diagnosed with chronic low back pain.
DR. RAKEL: You mentioned about reimbursement, which can be a significant barrier. There’s a study I just reviewed in the journal Spine that looked at what the patients perceived as most helpful for their low back pain. The number one response was massage. Number two was chiropractic therapy and OMT, and the last was conventional medicine. Unfortunately, massage isn’t covered by most reimbursement plans and acupuncture, included in the National Institute for Health and Care Excellence (NICE) guidelines,3 is also not covered. When you look at the cost-benefit of acupuncture versus epidural steroids, there’s a tremendous difference favoring acupuncture.7–10
So what you’re saying, Dr. King, is that this research is going to support the reimbursement for manual therapy whether that be OMT or chiropractic therapy?
DR. KING: Yes.
DR. RAKEL: Is that happening now? Isn’t OMT covered by most insurances?
DR. KING: It is. In the osteopathic professional societies that I belong to, these issues come up; for example, a certain third-party carrier would deny reimbursement for OMT services. We have been increasingly successful in educating the third-party carriers that there is a scientifically demonstrated benefit for manual medicine and manual therapy. This reimbursement advocacy based on evidenced-based research is an important element in making sure that it is readily available. If the third-party carriers accept the benefits of OMT, it will help research go forward. I’m just amazed that the interested companies don’t read the scientific literature; they seem to make us prove points. When the professional organizations have the opportunity to show them the evidence, the insurance companies say, “Well, yes, I guess we’ll have to reimburse it.”
The other element that I observed when I was in practice in San Diego and now in Madison, Wisconsin, is that if the patients who have benefited request that their coverage for OMT be increased, the insurance companies, especially the health maintenance organizations, respond and increase coverage, as the trend is for patient improvement and overall less insurance company payments for certain musculoskeletal conditions. Therefore, patient advocacy has helped, in my experience, in receiving sufficient reimbursement for the delivery of hands-on applications in health care.
DR. RAKEL: As we transition into our next topic with Dr. Schubiner, Dr. King, I know you have, as they say in the business, good hands. In your care of patients, it’s much more than just manipulation. Would you mind just touching quickly on that? You do more than just manipulation. In your delivery of care with your hands on the patient, what do you think makes the biggest difference in your ability to influence their outcomes?
DR. KING: I talk to the patient while I’m doing a 20- to 25-minute OMT service, about their life. Often, to a patient complaining of low back pain, I’ll ask, “Who’s the pain in your back?” Sometimes I refer to anatomy below the low back, but it gets the patient to think about their pain and talk about it, thus establishing a more direct mind-body connection.
My experience from body-mind-spirit integrative medicine is that if I’m able to address where the somatic dysfunction, that is, the malalignment, is, I associate it with the mental, emotional, and psychosocial components that the patient almost cannot resist. It’s what comes to their mind when I say, “Okay, who’s the pain in your rear?” They then start talking about some event or some situation, and you can feel the tissues of the low back respond even better when their mind is engaged in the full component of the true causes of the pain.
Sometimes, the key element in the benefit of the OMT is just re-living the incident itself—the injury, the fall, and the strain—and they go back to that moment of impact. You may be able to remind the person of the injury time that they may have forgotten about, sometimes on purpose. Just by undergoing the mental process of remembering the fear and the anger of falling or straining, they can remember the “injury,” “Oh darn, that hurts now.” If you take them back to the time of the initiation of the injury in the treatment of musculoskeletal malalignment, you do get a more effective, successful treatment, if you’re able to combine the mental and emotional as well as the physical aspects at the same time during the treatment.
So, yes, I go out of my way to do that. I think it really establishes a strong doctor-patient relationship when you have that kind of time, that 20- to 25-minute dialogue. The patients appreciate that you’re taking the time to do it, that you’re not only talking to them but you are touching them.
DR. RAKEL: That is a beautiful segue way to iterate the importance of the complexity of human beings with conditions such as low back pain. Dr. Schubiner has conducted research in this area and has developed patient resources.11 So, Dr. Schubiner, would you mind sharing some of your insights about how you might encourage us to explore this mind-body connection in our everyday practice of this common condition?
DR. SCHUBINER: There are 3 areas that I thought I could talk about. First, there is some cutting-edge neuroscience on the relationship between emotions and pain. Second, there’s some data on mind/body approaches to chronic pain, musculoskeletal pain, and fibromyalgia. And finally, I will briefly discuss how I approach this problem.
First, there’s been some cutting-edge research on the relationship between emotions and pain. At the University of California at Los Angeles, they’ve showed that social exclusion causes activation of the anterior cingulate cortex and decreases the pain threshold.12
Ethan Kross at the University of Michigan has shown that creating physical pain causes activation of the same pathways in the brain, ie, the so-called pain pathways, that are activated by causing someone to have emotional pain.13 John Burns, in Chicago, has shown that asking people with low back pain to recall a time when they were particularly angry causes spasm of the muscles of the low back, and that holding in emotion or asking people to suppress emotion decreases pains threshold.14,15 Finally, Apkarian and colleagues have shown that activation of emotional pathways in the brain (the nucleus accumbens in the limbic system) predicts which patients with subacute back pain are more likely to develop chronic back pain.16
The data on mind/body approaches to chronic musculoskeletal pain, primarily back pain, show that mindfulness mediation, cognitive behavioral therapies, acceptance and commitment therapy, loving/kindness meditative therapies, and expressive writing therapies are effective for this condition. However, the effect sizes are relatively small, in the range of 0.3 to 0.5.17
When these approaches are used, they generally do not challenge the traditional biomedical model that assumed that all people with back pain have a musculoskeletal condition or some kind of ongoing tissue damage process. However, if you follow the back pain research closely, you realize that 85% of back pain cannot be diagnosed accurately, according to Richard Deyo, on the basis of current testing that we have available.18
In my practice, I try to help determine if each patient has primarily a tissue-damage problem or, what I would call, a nerve-pathway problem. A nerve pathway consists of the connection of millions of neurons in the brain that have been trained to create some reaction in the body, such as pathways of how to talk, walk, sign one’s name, ride a bicycle, or swing a golf club. A recent realization is that nerve pathways can be causes of pain. If one has a nerve pathway problem, the pain, of course, is very real and often is as severe, or even more severe, as a tissue-damage–related pain. We have discovered that nerve pathway pain, whether it’s diagnosed as fibromyalgia, neck or back pain, headache, or any other painful condition in the body, can be dramatically reduced or even eliminated. The bottom line is that the majority of people with these painful conditions do not have ongoing tissue injury but have nerve pathway-related pain.
In brief, let me describe the approach that I have taken to reversing pain from nerve pathway-related conditions.11 First, I rule out a structural process such as a tumor, fracture, infection, or condition that causes clear evidence of nerve compression (ie, an abnormal neurologic examination). The program involves the following: (1) educate patients that they do not have tissue damage and that they can get better; (2) teach them to take control of the pain by removing the fear of pain and literally “telling the pain to go away” along with meditative and visualization techniques; (3) process past and current life stressors emotionally (using a therapy known as intensive short-term dynamic psychotherapy18); and (4) help them make positive changes in their life. We have conducted research to evaluate this model in patients with fibromyalgia19 and those with back and neck pain.20 The data are encouraging and show large effect sizes of approximately 1.1 to 1.4.
After a relatively brief 4-week intervention, approximately 50% of patients have more than a 50% reduction in pain at a 6-month follow-up assessment, which is obviously a very dramatic reduction in pain. The key to these results is in helping patients understand that they have a nerve-pathway problem as opposed to a tissue-damage problem and empower them to believe that they can actually overcome the pain. We offer them behavioral strategies to help them eliminate the pain and, most importantly, work on the emotions, as Dr. King was discussing. I’ve been using very specific techniques, such as intensive short-term dynamic psychotherapy, for dealing with emotions such as anger, guilt, fear, and sadness or grief to help people express and release the emotions that, from my point of view, comprise the underlying cause of the origin and perpetuation of nerve pathway pain.
DR. SCHUBINER: As I mentioned earlier, it’s been shown that emotional factors can cause significant muscle spasm, which can then, of course, create malalignments. So, treating the malalignment is important, but it is often necessary to identify the root cause. Studies have shown that patients with low back pain undergo a process known as “central sensitization,”21 as do patients with fibromyalgia.
When we look carefully at the new research on central sensitization, we’re beginning to realize that chronic pain is primarily a disorder of the brain, and not a disorder of the body.
DR. RAKEL: Our patients have visited Dr. King and Dr. Schubiner and are doing quite well, but they need to learn how to become empowered to understand what they can do to maintain this benefit over time. Dr. Kurisu, this is an area that interests you, and you have expertise in working to empower the patient and to work with some of our other colleagues to recondition the body and strengthen it to increase support. There’s been excellent research on yoga therapy for this as well as physical therapy.22–25
How can we sustain these benefits over time?
DR. KURISU: Well, one of the main questions I always get from patients is the question, “What can I do to prevent this from occurring? What are some of the things I can do at home?” From a primary care perspective for a provider examining a patient with low back pain, I believe that physical therapists or some manual therapists are some of the more underutilized people and referral sources that we have.
What I have done in my practice is to establish a very close network of people that I refer to: physical therapists, yoga therapists, massage therapists, etc. I also perform osteopathic manipulation. It is important for a provider to know all the therapists at a personal level to know what type of styles and techniques of therapy they will offer. It is important to remember that not all physical therapy is the same. Any provider should become educated about what type of exercises should be done for what specific condition. It’s one of those things that patients ask about when you demonstrate an exercise to them and you’re showing them how to do it.
Physical therapists excel at this because they have a lot of time to spend with the patient, while educating the patient about their condition. They also give the patients handouts listing different exercises and stretches for the patient to perform at home. I tend to call these handouts “homework.” I always tell the patient that the main trick is that you MUST do your homework because all of the research shows that you show improvement when you actually invest time and energy into your recovery.
Most of the patients that I’ve seen, and ones that I’ve talked to, enjoy the hands-on therapy. They enjoy the one-on-one attention they get from a provider who performs manual therapy. They enjoy that aspect a lot more than just taking a medicine that’s prescribed to them. So, I tell all my family medicine colleagues to try to think of writing a prescription for manual therapy (OMT, physical therapy, or chiropractic) instead of a prescription for medication or other interventions.
Therefore, if the prescription for physical therapy runs out, they might need a refill. Then, exactly as all providers do for medications, one can write a refill for that prescription of physical therapy. The physical aspect of chronic low back pain is just one part of the picture.
The emotional aspect is another part. We have a whole network of people to refer to in the mind/body area—psychologists, psychiatrists, and mind/body therapists—to help these patients deal with the chronicity of their pain. In addition, we attempt to empower ourselves as physicians to become more involved in the patient’s care plan. Too often, we see physicians treating low back pain with either just medications or physical therapy. However, you might not see the patient again for 6 to 8 weeks, and so much can happen in that time.
The sports medicine doctors do this very well, and they can actually write out a care plan for the patient. This goes along with the European guidelines for prevention of low back pain.26 These guidelines were released in 2004, and they group populations into 3 different groups. I’ve used a modified version of that. So, the first group is the general population dealing with low back pain, which includes the need for psychological therapy, physical therapy, and exercises and stretches.
The second group is of workers, because some people are hurt on the job and they need a specific guideline for when to go back to work and some sort of limitations that they have to maintain at work. The third group is school-age children, but I expand on this to include athletes as well. Many athletes really want a plan of action for when they can get back to a certain level in their sport. Patients can then take this plan with them and take it to their coaches.
There is a lot of one-on-one intervention that goes on when patients are dealing with a chronic injury or chronic pain. I would recommend you always make sure that you’re extending out to that network of people that you refer to. I have weekly conversations with the psychologists as well as the physical therapist that we refer patients to, to make sure that we’re all on the same page and no one’s giving overlapping advice on any treatment.
DR. RAKEL: I’ve heard from each of you about the importance of some key areas. Number one is the relationship, as Dr. Kurisu said—the quarterback, who is someone to help guide and create a plan to communicate among these different professionals to make sure we’re not overlapping treatment.
Also, it is important to match the patient to the therapy that they feel will work best for them. We’re not going to send everybody to a yoga therapist. I might not send everybody to physical therapists. If we can best match the patient’s belief system to the most appropriate team member, we will likely get a better clinical response.
Dr. Kurisu, you said it’s important when you get to know them so you can best make that match. Everybody talked about time. Let me mention the importance of laying on hands and then using the art of manual therapy to help reduce that pain and discomfort while also addressing the importance of the emotions and how internalized negative emotions might exacerbate or even trigger muscle spasm.
DR. SCHUBINER: One very important thing that I learned from you, Dr. Rakel, is that often, the majority of the therapeutic benefit results from the doctor-patient relationship. The most important ability a clinician has is the ability to listen, to take time with the patient, and to create an agreement between the doctor and the patient on defining the problem and deciding on the best form of therapy. So, I think you’re absolutely right in emphasizing that point.
DR. RAKEL: I think people get disgruntled when they perceive that they’re seeing silos of care that are just focused on a procedure or an imaging study that sees them as an object. I think everybody’s concerned about that. So I’m just going to encourage a little freedom. Any other areas that anybody wants to talk about before we finish?
DR. SCHUBINER: The other major mainstream medical approach to chronic pain comes from treatment in specialized pain clinics. Pain clinics initially arose in this country due to the widespread undertreatment of pain for people with severe pain often caused by cancer and other structural processes. The data that I’ve seen from pain programs do not typically show actual pain reduction, but rather improved coping with pain. However, I think we have shown that you can achieve significant reductions in pain. That process can only occur when we promote self-care on the part of the patient.
We have all been talking about this aspect of care. It’s promoting what the patient can do for themselves. If chronic pain is a condition of the brain, we have to help patients activate the parts of their mind, brain, and spirit that lead to healing. Healing consists of not only healing the back, but also working to heal the whole person. When we think about healing the whole person, we’re helping people to define their meaning and purpose in life. We’re promoting a deep social connection and encouraging people to align with their true selves.
DR. RAKEL: I think that’s an exciting point that you made very well, Dr. Schubiner. If I was to open a new low back pain clinic, we can change our intention from naming it the Chronic Low Back Pain Clinic to the Myofascial Health and Resiliency Clinic. That simple intention changes everything and helps the patient believe that they can get better.
DR. KING: I always appreciate it when a patient says that the work that I’ve done gives them hope. They have hope that they can get well. As soon as I hear a patient say that, I know that we’ve activated this part of their being that they need to utilize for their eventual resolution as to how “well” they can get. So, I experience an idea of what we do when giving the patient hope.
For example, we know that pain causes fear. We also know that fear causes pain. This vicious cycle is responsible for a tremendous amount of suffering. The techniques that we’re talking about can interrupt that cycle and lead to healing.
DR. RAKEL: That’s supported by the research on neuroplasticity and how we can change the brain.27 I think the most important thing I can do is convey to the patient that I believe they can get over the pain. Sometimes, they need to hear that from their health care provider. That may not always be the case, as we have to be real and truthful. But, having someone believe in their healing potential is half the journey.
DR. KURISU: Just a comment on the hope that Dr. King was talking about. Many a times, these patients have bounced around from many different pain clinics and many different specialists. The model that was presented to them is just more medications or conventional surgeries. So, when they finally get that sense of hope or finally feel that sense of empowerment, the light bulb goes on and they feel like, “Oh well, I can control this. This pain is a part of me as much as I’m a part of it. I can take these steps to help prevent this from happening.”
DR. SCHUBINER: It’s not false hope. It’s the truth, and what I always tell my patients is that “the truth will set you free.”
DR. RAKEL: Any final words anyone?
DR. KING: We have not mentioned that word “spirit” in the body–mind–spirit dimension. I think we talked around it in the mental-emotional-psychosocial aspect. This is something that I think the doctor-patient relationship, and the uniqueness of that, addresses as a relationship of one being with another being. How we operationally define that for research, is something to be seen. For the sake of our discussion, I don’t think we can avoid matters of “the spirit” or the soul. I just wanted to mention that because I think it is embodied through the approach where you’re talking to your patient and you’re putting your hands on them as all of us in the manual medicine/manual therapy will do.
DR. SCHUBINER: There is neurological research being conducted on this topic.28
When you activate social connectivity, you’re activating a sense of awe, and you’re activating the parts of the brain such as the dorsolateral prefrontal cortex that turn off the amygdala and the anterior cingulate cortex pathways that create pain. So, you’re absolutely right.
DR. RAKEL: Isn’t this a great opportunity for us to expand our strategies and research skills to look at the outcomes and the pragmatic controlled trials that ask us to determine what influences our quality of life the most? If we look at that bigger picture, we can’t help but bring up topics like meaning, belief, emotions, and spirituality. If we are going to create expertise to better understand how complex systems heal, we have to include these important ingredients.

Chronic back pain is among the most common patient complaints. Its prevalence and impact have spawned a rapidly expanding range of tests and treatments. Some of these have become widely used for indications that are not well validated, leading to uncertainty about efficacy and safety, increasing complication rates, and marketing abuses. Recent studies document a 629% increase in Medicare expenditures for epidural steroid injections, a 423% increase in expenditures for opioids for back pain, a 307% increase in the number of lumbar magnetic resonance images among Medicare beneficiaries, and a 220% increase in spinal fusion surgery rates. The limited studies available suggest that these increases have not been accompanied by population-level improvements in patient outcomes or disability rates. We suggest a need for a better understanding of the basic science of pain mechanisms, more rigorous and independent trials of many treatments, a stronger regulatory stance toward approval and postmarketing surveillance of new drugs and devices for chronic pain, and a chronic disease model for managing chronic back pain.1
Despite this increase in investment, we have not seen a significant reduction in morbidity of low back pain.1
When we refer to integrative medicine, what we’re actually talking about is combining the therapies that work best to understand how humans heal within complex systems. Low back pain is a perfect example of how complexity based on biopsychosocial-spiritual influences can influence the severity of pain as well as suffering.
The Centers for Disease Control and Prevention National Health statistics report2 showed that low back pain was, by far, the most common condition for which patients seek complementary and alternative medicine care. We hope to eliminate these terms and refer to them instead as just good medicine, where the research guides us toward what works best. With this goal in mind, the National Institute of Clinical Excellence in England released their guidelines for low back pain that were published in the British Medical Journal.3 They summarized those therapies that had the best evidence for yielding beneficial effects.
The therapies that had the most benefit with the least potential for harm were physical therapy but not traction, exercise, mind/body influences including psychology, acupuncture, and surgery when indicated, particularly for severe radicular pain. That’s almost a different diagnosis when you have severe radicular pain. We will focus more on low back pain and chronic low back pain, without significant radicular symptoms. The guidelines also supported nonsteroidal anti-inflammatory drugs.
Two things that the guidelines did not support in this evidence-based review were epidural steroids and opioids. We use opioids a lot, but the research shows that maybe we shouldn’t do so. The Danish health and morbidity study4 of more than 10 000 patients who were treated with opioids for noncancer pain showed that the patients did not meet any of the 3 outcome measures associated with pain management. Surprisingly, opioids did not result in improved function, improved quality of life, or a reduction in pain.
When we talk about how to deal with these different aspects of pain, we’d like to use the expertise of our panel to focus on 3 main therapeutic areas. We will use a 3-legged stool model to highlight each of these 3 therapeutic areas. The first leg is the external or physical parts of low back pain, including structure and mechanics. The second leg is the internal or emotional aspect, ie, the importance of stress and emotions on why that pain might be persisting. The third leg of the stool is reconditioning. How can we get the body to be strong and supportive? How can we work with our colleagues to create these interdisciplinary teams to yield better outcomes, particularly as accountable care organizations become more popular with regard to improving outcome measures for low back pain? What professionals would we want to work with for the best outcome?
Dr. King, I’d like to start with you. You could talk about exploring the external and the physical piece. You have particular expertise in osteopathic manual therapy as well as research in this area. Would you mind sharing some of your insights with regard to manual therapy and the treatment of this condition?
DR. KING: In the present medical research context of needing to have your work be well justified by evidence-based medicine research, all the professions who use their hands in health care have been striving to generate acceptable research. At present, the chiropractic profession is probably the one that has produced the most practical research on spinal manipulation. The osteopathic profession has followed suit pretty well too. That’s where I have personally been involved in the research.
For instance, with chronic low back pain, this is one of the subjects where we actually have state-of-the-art evidence-based research. A systematic review and meta-analysis that was conducted by Licciardone et al and published in 2005,5 which is a Cochrane review level of evidence, describes all the necessary meta-analysis aspects indicating that osteopathic manipulative treatment (OMT) significantly reduces low back pain. From the osteopathic perspective, OMT is delivered to patients with the diagnoses of somatic dysfunction or malalignment of the vertebral column, as well as malalignment of the appendicular skeleton for upper and lower extremities. In this case, we’re talking about the low back.
We now have state-of-the-art evidence of the benefit of OMT for low back pain. This evidence has been established in practice guidelines published by the Agency for Healthcare Research and Quality.6 These guidelines indicate where OMT should be utilized in the treatment of chronic low back pain. This is in the context of conventional medical treatment of chronic low back pain, where essentially the guidelines say that OMT should be used. The administration of OMT typically occurs as a part of an outpatient visit, for either musculoskeletal pain or even for a sore throat, or the physician may have a day in his clinic schedule when all that is done is OMT—an OMT clinic if you will; this is my style of doing OMT. For a sore throat, OMT can quickly be done to enhance lymphatic drainage and augment the healing process and even help any prescribed medication get to the infected area through improved circulation.
We have reached this level of medical research. The outcome is that, in my experience at least, there is very little resistance on the part of third-party carriers including Medicare to reimburse people for the delivery of OMT wherein the diagnosis is low back pain and particularly, chronic low back pain. This has been very helpful because the reimbursement element is critical in order to provide this service.
There are several other research initiatives, one of which was undertaken by Licciardone et al,7 in which OMT for 488 subjects was compared for chronic low back pain by using ultrasound. I was a treatment provider in that study, the results of which support the meta-analysis discussed above. The first publication derived from this study reports a subgroup analysis that assesses cytokine production after OMT. The results were that the cytokine interleukin 6 was correlated with back pain severity.8
From the research side, we are gradually—certainly between the osteopathic and the chiropractic professions—generating the evidence that spinal manipulation, the hands-on work, is of definite benefit in the care of patients who have been diagnosed with chronic low back pain.
DR. RAKEL: You mentioned about reimbursement, which can be a significant barrier. There’s a study I just reviewed in the journal Spine that looked at what the patients perceived as most helpful for their low back pain. The number one response was massage. Number two was chiropractic therapy and OMT, and the last was conventional medicine. Unfortunately, massage isn’t covered by most reimbursement plans and acupuncture, included in the National Institute for Health and Care Excellence (NICE) guidelines,3 is also not covered. When you look at the cost-benefit of acupuncture versus epidural steroids, there’s a tremendous difference favoring acupuncture.7–10
So what you’re saying, Dr. King, is that this research is going to support the reimbursement for manual therapy whether that be OMT or chiropractic therapy?
DR. KING: Yes.
DR. RAKEL: Is that happening now? Isn’t OMT covered by most insurances?
DR. KING: It is. In the osteopathic professional societies that I belong to, these issues come up; for example, a certain third-party carrier would deny reimbursement for OMT services. We have been increasingly successful in educating the third-party carriers that there is a scientifically demonstrated benefit for manual medicine and manual therapy. This reimbursement advocacy based on evidenced-based research is an important element in making sure that it is readily available. If the third-party carriers accept the benefits of OMT, it will help research go forward. I’m just amazed that the interested companies don’t read the scientific literature; they seem to make us prove points. When the professional organizations have the opportunity to show them the evidence, the insurance companies say, “Well, yes, I guess we’ll have to reimburse it.”
The other element that I observed when I was in practice in San Diego and now in Madison, Wisconsin, is that if the patients who have benefited request that their coverage for OMT be increased, the insurance companies, especially the health maintenance organizations, respond and increase coverage, as the trend is for patient improvement and overall less insurance company payments for certain musculoskeletal conditions. Therefore, patient advocacy has helped, in my experience, in receiving sufficient reimbursement for the delivery of hands-on applications in health care.
DR. RAKEL: As we transition into our next topic with Dr. Schubiner, Dr. King, I know you have, as they say in the business, good hands. In your care of patients, it’s much more than just manipulation. Would you mind just touching quickly on that? You do more than just manipulation. In your delivery of care with your hands on the patient, what do you think makes the biggest difference in your ability to influence their outcomes?
DR. KING: I talk to the patient while I’m doing a 20- to 25-minute OMT service, about their life. Often, to a patient complaining of low back pain, I’ll ask, “Who’s the pain in your back?” Sometimes I refer to anatomy below the low back, but it gets the patient to think about their pain and talk about it, thus establishing a more direct mind-body connection.
My experience from body-mind-spirit integrative medicine is that if I’m able to address where the somatic dysfunction, that is, the malalignment, is, I associate it with the mental, emotional, and psychosocial components that the patient almost cannot resist. It’s what comes to their mind when I say, “Okay, who’s the pain in your rear?” They then start talking about some event or some situation, and you can feel the tissues of the low back respond even better when their mind is engaged in the full component of the true causes of the pain.
Sometimes, the key element in the benefit of the OMT is just re-living the incident itself—the injury, the fall, and the strain—and they go back to that moment of impact. You may be able to remind the person of the injury time that they may have forgotten about, sometimes on purpose. Just by undergoing the mental process of remembering the fear and the anger of falling or straining, they can remember the “injury,” “Oh darn, that hurts now.” If you take them back to the time of the initiation of the injury in the treatment of musculoskeletal malalignment, you do get a more effective, successful treatment, if you’re able to combine the mental and emotional as well as the physical aspects at the same time during the treatment.
So, yes, I go out of my way to do that. I think it really establishes a strong doctor-patient relationship when you have that kind of time, that 20- to 25-minute dialogue. The patients appreciate that you’re taking the time to do it, that you’re not only talking to them but you are touching them.
DR. RAKEL: That is a beautiful segue way to iterate the importance of the complexity of human beings with conditions such as low back pain. Dr. Schubiner has conducted research in this area and has developed patient resources.11 So, Dr. Schubiner, would you mind sharing some of your insights about how you might encourage us to explore this mind-body connection in our everyday practice of this common condition?
DR. SCHUBINER: There are 3 areas that I thought I could talk about. First, there is some cutting-edge neuroscience on the relationship between emotions and pain. Second, there’s some data on mind/body approaches to chronic pain, musculoskeletal pain, and fibromyalgia. And finally, I will briefly discuss how I approach this problem.
First, there’s been some cutting-edge research on the relationship between emotions and pain. At the University of California at Los Angeles, they’ve showed that social exclusion causes activation of the anterior cingulate cortex and decreases the pain threshold.12
Ethan Kross at the University of Michigan has shown that creating physical pain causes activation of the same pathways in the brain, ie, the so-called pain pathways, that are activated by causing someone to have emotional pain.13 John Burns, in Chicago, has shown that asking people with low back pain to recall a time when they were particularly angry causes spasm of the muscles of the low back, and that holding in emotion or asking people to suppress emotion decreases pains threshold.14,15 Finally, Apkarian and colleagues have shown that activation of emotional pathways in the brain (the nucleus accumbens in the limbic system) predicts which patients with subacute back pain are more likely to develop chronic back pain.16
The data on mind/body approaches to chronic musculoskeletal pain, primarily back pain, show that mindfulness mediation, cognitive behavioral therapies, acceptance and commitment therapy, loving/kindness meditative therapies, and expressive writing therapies are effective for this condition. However, the effect sizes are relatively small, in the range of 0.3 to 0.5.17
When these approaches are used, they generally do not challenge the traditional biomedical model that assumed that all people with back pain have a musculoskeletal condition or some kind of ongoing tissue damage process. However, if you follow the back pain research closely, you realize that 85% of back pain cannot be diagnosed accurately, according to Richard Deyo, on the basis of current testing that we have available.18
In my practice, I try to help determine if each patient has primarily a tissue-damage problem or, what I would call, a nerve-pathway problem. A nerve pathway consists of the connection of millions of neurons in the brain that have been trained to create some reaction in the body, such as pathways of how to talk, walk, sign one’s name, ride a bicycle, or swing a golf club. A recent realization is that nerve pathways can be causes of pain. If one has a nerve pathway problem, the pain, of course, is very real and often is as severe, or even more severe, as a tissue-damage–related pain. We have discovered that nerve pathway pain, whether it’s diagnosed as fibromyalgia, neck or back pain, headache, or any other painful condition in the body, can be dramatically reduced or even eliminated. The bottom line is that the majority of people with these painful conditions do not have ongoing tissue injury but have nerve pathway-related pain.
In brief, let me describe the approach that I have taken to reversing pain from nerve pathway-related conditions.11 First, I rule out a structural process such as a tumor, fracture, infection, or condition that causes clear evidence of nerve compression (ie, an abnormal neurologic examination). The program involves the following: (1) educate patients that they do not have tissue damage and that they can get better; (2) teach them to take control of the pain by removing the fear of pain and literally “telling the pain to go away” along with meditative and visualization techniques; (3) process past and current life stressors emotionally (using a therapy known as intensive short-term dynamic psychotherapy18); and (4) help them make positive changes in their life. We have conducted research to evaluate this model in patients with fibromyalgia19 and those with back and neck pain.20 The data are encouraging and show large effect sizes of approximately 1.1 to 1.4.
After a relatively brief 4-week intervention, approximately 50% of patients have more than a 50% reduction in pain at a 6-month follow-up assessment, which is obviously a very dramatic reduction in pain. The key to these results is in helping patients understand that they have a nerve-pathway problem as opposed to a tissue-damage problem and empower them to believe that they can actually overcome the pain. We offer them behavioral strategies to help them eliminate the pain and, most importantly, work on the emotions, as Dr. King was discussing. I’ve been using very specific techniques, such as intensive short-term dynamic psychotherapy, for dealing with emotions such as anger, guilt, fear, and sadness or grief to help people express and release the emotions that, from my point of view, comprise the underlying cause of the origin and perpetuation of nerve pathway pain.
DR. SCHUBINER: As I mentioned earlier, it’s been shown that emotional factors can cause significant muscle spasm, which can then, of course, create malalignments. So, treating the malalignment is important, but it is often necessary to identify the root cause. Studies have shown that patients with low back pain undergo a process known as “central sensitization,”21 as do patients with fibromyalgia.
When we look carefully at the new research on central sensitization, we’re beginning to realize that chronic pain is primarily a disorder of the brain, and not a disorder of the body.
DR. RAKEL: Our patients have visited Dr. King and Dr. Schubiner and are doing quite well, but they need to learn how to become empowered to understand what they can do to maintain this benefit over time. Dr. Kurisu, this is an area that interests you, and you have expertise in working to empower the patient and to work with some of our other colleagues to recondition the body and strengthen it to increase support. There’s been excellent research on yoga therapy for this as well as physical therapy.22–25
How can we sustain these benefits over time?
DR. KURISU: Well, one of the main questions I always get from patients is the question, “What can I do to prevent this from occurring? What are some of the things I can do at home?” From a primary care perspective for a provider examining a patient with low back pain, I believe that physical therapists or some manual therapists are some of the more underutilized people and referral sources that we have.
What I have done in my practice is to establish a very close network of people that I refer to: physical therapists, yoga therapists, massage therapists, etc. I also perform osteopathic manipulation. It is important for a provider to know all the therapists at a personal level to know what type of styles and techniques of therapy they will offer. It is important to remember that not all physical therapy is the same. Any provider should become educated about what type of exercises should be done for what specific condition. It’s one of those things that patients ask about when you demonstrate an exercise to them and you’re showing them how to do it.
Physical therapists excel at this because they have a lot of time to spend with the patient, while educating the patient about their condition. They also give the patients handouts listing different exercises and stretches for the patient to perform at home. I tend to call these handouts “homework.” I always tell the patient that the main trick is that you MUST do your homework because all of the research shows that you show improvement when you actually invest time and energy into your recovery.
Most of the patients that I’ve seen, and ones that I’ve talked to, enjoy the hands-on therapy. They enjoy the one-on-one attention they get from a provider who performs manual therapy. They enjoy that aspect a lot more than just taking a medicine that’s prescribed to them. So, I tell all my family medicine colleagues to try to think of writing a prescription for manual therapy (OMT, physical therapy, or chiropractic) instead of a prescription for medication or other interventions.
Therefore, if the prescription for physical therapy runs out, they might need a refill. Then, exactly as all providers do for medications, one can write a refill for that prescription of physical therapy. The physical aspect of chronic low back pain is just one part of the picture.
The emotional aspect is another part. We have a whole network of people to refer to in the mind/body area—psychologists, psychiatrists, and mind/body therapists—to help these patients deal with the chronicity of their pain. In addition, we attempt to empower ourselves as physicians to become more involved in the patient’s care plan. Too often, we see physicians treating low back pain with either just medications or physical therapy. However, you might not see the patient again for 6 to 8 weeks, and so much can happen in that time.
The sports medicine doctors do this very well, and they can actually write out a care plan for the patient. This goes along with the European guidelines for prevention of low back pain.26 These guidelines were released in 2004, and they group populations into 3 different groups. I’ve used a modified version of that. So, the first group is the general population dealing with low back pain, which includes the need for psychological therapy, physical therapy, and exercises and stretches.
The second group is of workers, because some people are hurt on the job and they need a specific guideline for when to go back to work and some sort of limitations that they have to maintain at work. The third group is school-age children, but I expand on this to include athletes as well. Many athletes really want a plan of action for when they can get back to a certain level in their sport. Patients can then take this plan with them and take it to their coaches.
There is a lot of one-on-one intervention that goes on when patients are dealing with a chronic injury or chronic pain. I would recommend you always make sure that you’re extending out to that network of people that you refer to. I have weekly conversations with the psychologists as well as the physical therapist that we refer patients to, to make sure that we’re all on the same page and no one’s giving overlapping advice on any treatment.
DR. RAKEL: I’ve heard from each of you about the importance of some key areas. Number one is the relationship, as Dr. Kurisu said—the quarterback, who is someone to help guide and create a plan to communicate among these different professionals to make sure we’re not overlapping treatment.

I might not send everybody to physical therapists. If we can best match the patient’s belief system to the most appropriate team member, we will likely get a better clinical response.
Dr. Kurisu, you said it’s important when you get to know them so you can best make that match. Everybody talked about time. Let me mention the importance of laying on hands and then using the art of manual therapy to help reduce that pain and discomfort while also addressing the importance of the emotions and how internalized negative emotions might exacerbate or even trigger muscle spasm.
DR. SCHUBINER: One very important thing that I learned from you, Dr. Rakel, is that often, the majority of the therapeutic benefit results from the doctor-patient relationship. The most important ability a clinician has is the ability to listen, to take time with the patient, and to create an agreement between the doctor and the patient on defining the problem and deciding on the best form of therapy. So, I think you’re absolutely right in emphasizing that point.
DR. RAKEL: I think people get disgruntled when they perceive that they’re seeing silos of care that are just focused on a procedure or an imaging study that sees them as an object. I think everybody’s concerned about that. So I’m just going to encourage a little freedom. Any other areas that anybody wants to talk about before we finish?
DR. SCHUBINER: The other major mainstream medical approach to chronic pain comes from treatment in specialized pain clinics.

When we think about healing the whole person, we’re helping people to define their meaning and purpose in life. We’re promoting a deep social connection and encouraging people to align with their true selves.
DR. RAKEL: I think that’s an exciting point that you made very well, Dr. Schubiner. If I was to open a new low back pain clinic, we can change our intention from naming it the Chronic Low Back Pain Clinic to the Myofascial Health and Resiliency Clinic.

The model that was presented to them is just more medications or conventional surgeries. So, when they finally get that sense of hope or finally feel that sense of empowerment, the light bulb goes on and they feel like, “Oh well, I can control this. This pain is a part of me as much as I’m a part of it. I can take these steps to help prevent this from happening.”
DR. SCHUBINER: It’s not false hope. It’s the truth, and what I always tell my patients is that “the truth will set you free.”
DR. RAKEL: Any final words anyone?
DR. KING: We have not mentioned that word “spirit” in the body–mind–spirit dimension. I think we talked around it in the mental-emotional-psychosocial aspect. This is something that I think the doctor-patient relationship, and the uniqueness of that, addresses as a relationship of one being with another being. How we operationally define that for research, is something to be seen. For the sake of our discussion, I don’t think we can avoid matters of “the spirit” or the soul. I just wanted to mention that because I think it is embodied through the approach where you’re talking to your patient and you’re putting your hands on them as all of us in the manual medicine/manual therapy will do.
DR. SCHUBINER: There is neurological research being conducted on this topic.28
When you activate social connectivity, you’re activating a sense of awe, and you’re activating the parts of the brain such as the dorsolateral prefrontal cortex that turn off the amygdala and the anterior cingulate cortex pathways that create pain. So, you’re absolutely right.
DR. RAKEL: Isn’t this a great opportunity for us to expand our strategies and research skills to look at the outcomes and the pragmatic controlled trials that ask us to determine what influences our quality of life the most? If we look at that bigger picture, we can’t help but bring up topics like meaning, belief, emotions, and spirituality. If we are going to create expertise to better understand how complex systems heal, we have to include these important ingredients.

Chronic back pain is among the most common patient complaints. Its prevalence and impact have spawned a rapidly expanding range of tests and treatments. Some of these have become widely used for indications that are not well validated, leading to uncertainty about efficacy and safety, increasing complication rates, and marketing abuses. Recent studies document a 629% increase in Medicare expenditures for epidural steroid injections, a 423% increase in expenditures for opioids for back pain, a 307% increase in the number of lumbar magnetic resonance images among Medicare beneficiaries, and a 220% increase in spinal fusion surgery rates. The limited studies available suggest that these increases have not been accompanied by population-level improvements in patient outcomes or disability rates. We suggest a need for a better understanding of the basic science of pain mechanisms, more rigorous and independent trials of many treatments, a stronger regulatory stance toward approval and postmarketing surveillance of new drugs and devices for chronic pain, and a chronic disease model for managing chronic back pain.1
Despite this increase in investment, we have not seen a significant reduction in morbidity of low back pain.1
When we refer to integrative medicine, what we’re actually talking about is combining the therapies that work best to understand how humans heal within complex systems. Low back pain is a perfect example of how complexity based on biopsychosocial-spiritual influences can influence the severity of pain as well as suffering.
The Centers for Disease Control and Prevention National Health statistics report2 showed that low back pain was, by far, the most common condition for which patients seek complementary and alternative medicine care. We hope to eliminate these terms and refer to them instead as just good medicine, where the research guides us toward what works best. With this goal in mind, the National Institute of Clinical Excellence in England released their guidelines for low back pain that were published in the British Medical Journal.3 They summarized those therapies that had the best evidence for yielding beneficial effects.
The therapies that had the most benefit with the least potential for harm were physical therapy but not traction, exercise, mind/body influences including psychology, acupuncture, and surgery when indicated, particularly for severe radicular pain. That’s almost a different diagnosis when you have severe radicular pain. We will focus more on low back pain and chronic low back pain, without significant radicular symptoms. The guidelines also supported nonsteroidal anti-inflammatory drugs.
Two things that the guidelines did not support in this evidence-based review were epidural steroids and opioids. We use opioids a lot, but the research shows that maybe we shouldn’t do so. The Danish health and morbidity study4 of more than 10 000 patients who were treated with opioids for noncancer pain showed that the patients did not meet any of the 3 outcome measures associated with pain management. Surprisingly, opioids did not result in improved function, improved quality of life, or a reduction in pain.
When we talk about how to deal with these different aspects of pain, we’d like to use the expertise of our panel to focus on 3 main therapeutic areas. We will use a 3-legged stool model to highlight each of these 3 therapeutic areas. The first leg is the external or physical parts of low back pain, including structure and mechanics. The second leg is the internal or emotional aspect, ie, the importance of stress and emotions on why that pain might be persisting. The third leg of the stool is reconditioning. How can we get the body to be strong and supportive? How can we work with our colleagues to create these interdisciplinary teams to yield better outcomes, particularly as accountable care organizations become more popular with regard to improving outcome measures for low back pain? What professionals would we want to work with for the best outcome?
Dr. King, I’d like to start with you. You could talk about exploring the external and the physical piece. You have particular expertise in osteopathic manual therapy as well as research in this area. Would you mind sharing some of your insights with regard to manual therapy and the treatment of this condition?
DR. KING: In the present medical research context of needing to have your work be well justified by evidence-based medicine research, all the professions who use their hands in health care have been striving to generate acceptable research. At present, the chiropractic profession is probably the one that has produced the most practical research on spinal manipulation. The osteopathic profession has followed suit pretty well too. That’s where I have personally been involved in the research.
For instance, with chronic low back pain, this is one of the subjects where we actually have state-of-the-art evidence-based research. A systematic review and meta-analysis that was conducted by Licciardone et al and published in 2005,5 which is a Cochrane review level of evidence, describes all the necessary meta-analysis aspects indicating that osteopathic manipulative treatment (OMT) significantly reduces low back pain. From the osteopathic perspective, OMT is delivered to patients with the diagnoses of somatic dysfunction or malalignment of the vertebral column, as well as malalignment of the appendicular skeleton for upper and lower extremities. In this case, we’re talking about the low back.
We now have state-of-the-art evidence of the benefit of OMT for low back pain. This evidence has been established in practice guidelines published by the Agency for Healthcare Research and Quality.6 These guidelines indicate where OMT should be utilized in the treatment of chronic low back pain. This is in the context of conventional medical treatment of chronic low back pain, where essentially the guidelines say that OMT should be used. The administration of OMT typically occurs as a part of an outpatient visit, for either musculoskeletal pain or even for a sore throat, or the physician may have a day in his clinic schedule when all that is done is OMT—an OMT clinic if you will; this is my style of doing OMT. For a sore throat, OMT can quickly be done to enhance lymphatic drainage and augment the healing process and even help any prescribed medication get to the infected area through improved circulation.
We have reached this level of medical research. The outcome is that, in my experience at least, there is very little resistance on the part of third-party carriers including Medicare to reimburse people for the delivery of OMT wherein the diagnosis is low back pain and particularly, chronic low back pain. This has been very helpful because the reimbursement element is critical in order to provide this service.
There are several other research initiatives, one of which was undertaken by Licciardone et al,7 in which OMT for 488 subjects was compared for chronic low back pain by using ultrasound. I was a treatment provider in that study, the results of which support the meta-analysis discussed above. The first publication derived from this study reports a subgroup analysis that assesses cytokine production after OMT. The results were that the cytokine interleukin 6 was correlated with back pain severity.8
From the research side, we are gradually—certainly between the osteopathic and the chiropractic professions—generating the evidence that spinal manipulation, the hands-on work, is of definite benefit in the care of patients who have been diagnosed with chronic low back pain.
DR. RAKEL: You mentioned about reimbursement, which can be a significant barrier. There’s a study I just reviewed in the journal Spine that looked at what the patients perceived as most helpful for their low back pain. The number one response was massage. Number two was chiropractic therapy and OMT, and the last was conventional medicine. Unfortunately, massage isn’t covered by most reimbursement plans and acupuncture, included in the National Institute for Health and Care Excellence (NICE) guidelines,3 is also not covered. When you look at the cost-benefit of acupuncture versus epidural steroids, there’s a tremendous difference favoring acupuncture.7–10
So what you’re saying, Dr. King, is that this research is going to support the reimbursement for manual therapy whether that be OMT or chiropractic therapy?
DR. KING: Yes.
DR. RAKEL: Is that happening now? Isn’t OMT covered by most insurances?
DR. KING: It is. In the osteopathic professional societies that I belong to, these issues come up; for example, a certain third-party carrier would deny reimbursement for OMT services. We have been increasingly successful in educating the third-party carriers that there is a scientifically demonstrated benefit for manual medicine and manual therapy. This reimbursement advocacy based on evidenced-based research is an important element in making sure that it is readily available. If the third-party carriers accept the benefits of OMT, it will help research go forward. I’m just amazed that the interested companies don’t read the scientific literature; they seem to make us prove points. When the professional organizations have the opportunity to show them the evidence, the insurance companies say, “Well, yes, I guess we’ll have to reimburse it.”
The other element that I observed when I was in practice in San Diego and now in Madison, Wisconsin, is that if the patients who have benefited request that their coverage for OMT be increased, the insurance companies, especially the health maintenance organizations, respond and increase coverage, as the trend is for patient improvement and overall less insurance company payments for certain musculoskeletal conditions. Therefore, patient advocacy has helped, in my experience, in receiving sufficient reimbursement for the delivery of hands-on applications in health care.
DR. RAKEL: As we transition into our next topic with Dr. Schubiner, Dr. King, I know you have, as they say in the business, good hands. In your care of patients, it’s much more than just manipulation. Would you mind just touching quickly on that? You do more than just manipulation. In your delivery of care with your hands on the patient, what do you think makes the biggest difference in your ability to influence their outcomes?
DR. KING: I talk to the patient while I’m doing a 20- to 25-minute OMT service, about their life. Often, to a patient complaining of low back pain, I’ll ask, “Who’s the pain in your back?” Sometimes I refer to anatomy below the low back, but it gets the patient to think about their pain and talk about it, thus establishing a more direct mind-body connection.
My experience from body-mind-spirit integrative medicine is that if I’m able to address where the somatic dysfunction, that is, the malalignment, is, I associate it with the mental, emotional, and psychosocial components that the patient almost cannot resist. It’s what comes to their mind when I say, “Okay, who’s the pain in your rear?” They then start talking about some event or some situation, and you can feel the tissues of the low back respond even better when their mind is engaged in the full component of the true causes of the pain.
Sometimes, the key element in the benefit of the OMT is just re-living the incident itself—the injury, the fall, and the strain—and they go back to that moment of impact. You may be able to remind the person of the injury time that they may have forgotten about, sometimes on purpose. Just by undergoing the mental process of remembering the fear and the anger of falling or straining, they can remember the “injury,” “Oh darn, that hurts now.” If you take them back to the time of the initiation of the injury in the treatment of musculoskeletal malalignment, you do get a more effective, successful treatment, if you’re able to combine the mental and emotional as well as the physical aspects at the same time during the treatment.
So, yes, I go out of my way to do that. I think it really establishes a strong doctor-patient relationship when you have that kind of time, that 20- to 25-minute dialogue. The patients appreciate that you’re taking the time to do it, that you’re not only talking to them but you are touching them.
DR. RAKEL: That is a beautiful segue way to iterate the importance of the complexity of human beings with conditions such as low back pain. Dr. Schubiner has conducted research in this area and has developed patient resources.11 So, Dr. Schubiner, would you mind sharing some of your insights about how you might encourage us to explore this mind-body connection in our everyday practice of this common condition?
DR. SCHUBINER: There are 3 areas that I thought I could talk about. First, there is some cutting-edge neuroscience on the relationship between emotions and pain. Second, there’s some data on mind/body approaches to chronic pain, musculoskeletal pain, and fibromyalgia. And finally, I will briefly discuss how I approach this problem.
First, there’s been some cutting-edge research on the relationship between emotions and pain. At the University of California at Los Angeles, they’ve showed that social exclusion causes activation of the anterior cingulate cortex and decreases the pain threshold.12
Ethan Kross at the University of Michigan has shown that creating physical pain causes activation of the same pathways in the brain, ie, the so-called pain pathways, that are activated by causing someone to have emotional pain.13 John Burns, in Chicago, has shown that asking people with low back pain to recall a time when they were particularly angry causes spasm of the muscles of the low back, and that holding in emotion or asking people to suppress emotion decreases pains threshold.14,15 Finally, Apkarian and colleagues have shown that activation of emotional pathways in the brain (the nucleus accumbens in the limbic system) predicts which patients with subacute back pain are more likely to develop chronic back pain.16
The data on mind/body approaches to chronic musculoskeletal pain, primarily back pain, show that mindfulness mediation, cognitive behavioral therapies, acceptance and commitment therapy, loving/kindness meditative therapies, and expressive writing therapies are effective for this condition. However, the effect sizes are relatively small, in the range of 0.3 to 0.5.17
When these approaches are used, they generally do not challenge the traditional biomedical model that assumed that all people with back pain have a musculoskeletal condition or some kind of ongoing tissue damage process. However, if you follow the back pain research closely, you realize that 85% of back pain cannot be diagnosed accurately, according to Richard Deyo, on the basis of current testing that we have available.18
In my practice, I try to help determine if each patient has primarily a tissue-damage problem or, what I would call, a nerve-pathway problem. A nerve pathway consists of the connection of millions of neurons in the brain that have been trained to create some reaction in the body, such as pathways of how to talk, walk, sign one’s name, ride a bicycle, or swing a golf club. A recent realization is that nerve pathways can be causes of pain. If one has a nerve pathway problem, the pain, of course, is very real and often is as severe, or even more severe, as a tissue-damage–related pain. We have discovered that nerve pathway pain, whether it’s diagnosed as fibromyalgia, neck or back pain, headache, or any other painful condition in the body, can be dramatically reduced or even eliminated. The bottom line is that the majority of people with these painful conditions do not have ongoing tissue injury but have nerve pathway-related pain.
In brief, let me describe the approach that I have taken to reversing pain from nerve pathway-related conditions.11 First, I rule out a structural process such as a tumor, fracture, infection, or condition that causes clear evidence of nerve compression (ie, an abnormal neurologic examination). The program involves the following: (1) educate patients that they do not have tissue damage and that they can get better; (2) teach them to take control of the pain by removing the fear of pain and literally “telling the pain to go away” along with meditative and visualization techniques; (3) process past and current life stressors emotionally (using a therapy known as intensive short-term dynamic psychotherapy18); and (4) help them make positive changes in their life. We have conducted research to evaluate this model in patients with fibromyalgia19 and those with back and neck pain.20 The data are encouraging and show large effect sizes of approximately 1.1 to 1.4.
After a relatively brief 4-week intervention, approximately 50% of patients have more than a 50% reduction in pain at a 6-month follow-up assessment, which is obviously a very dramatic reduction in pain. The key to these results is in helping patients understand that they have a nerve-pathway problem as opposed to a tissue-damage problem and empower them to believe that they can actually overcome the pain. We offer them behavioral strategies to help them eliminate the pain and, most importantly, work on the emotions, as Dr. King was discussing. I’ve been using very specific techniques, such as intensive short-term dynamic psychotherapy, for dealing with emotions such as anger, guilt, fear, and sadness or grief to help people express and release the emotions that, from my point of view, comprise the underlying cause of the origin and perpetuation of nerve pathway pain.
DR. SCHUBINER: As I mentioned earlier, it’s been shown that emotional factors can cause significant muscle spasm, which can then, of course, create malalignments. So, treating the malalignment is important, but it is often necessary to identify the root cause. Studies have shown that patients with low back pain undergo a process known as “central sensitization,”21 as do patients with fibromyalgia.
When we look carefully at the new research on central sensitization, we’re beginning to realize that chronic pain is primarily a disorder of the brain, and not a disorder of the body.
DR. RAKEL: Our patients have visited Dr. King and Dr. Schubiner and are doing quite well, but they need to learn how to become empowered to understand what they can do to maintain this benefit over time. Dr. Kurisu, this is an area that interests you, and you have expertise in working to empower the patient and to work with some of our other colleagues to recondition the body and strengthen it to increase support. There’s been excellent research on yoga therapy for this as well as physical therapy.22–25
How can we sustain these benefits over time?
DR. KURISU: Well, one of the main questions I always get from patients is the question, “What can I do to prevent this from occurring? What are some of the things I can do at home?” From a primary care perspective for a provider examining a patient with low back pain, I believe that physical therapists or some manual therapists are some of the more underutilized people and referral sources that we have.
What I have done in my practice is to establish a very close network of people that I refer to: physical therapists, yoga therapists, massage therapists, etc. I also perform osteopathic manipulation. It is important for a provider to know all the therapists at a personal level to know what type of styles and techniques of therapy they will offer. It is important to remember that not all physical therapy is the same. Any provider should become educated about what type of exercises should be done for what specific condition. It’s one of those things that patients ask about when you demonstrate an exercise to them and you’re showing them how to do it.
Physical therapists excel at this because they have a lot of time to spend with the patient, while educating the patient about their condition. They also give the patients handouts listing different exercises and stretches for the patient to perform at home. I tend to call these handouts “homework.” I always tell the patient that the main trick is that you MUST do your homework because all of the research shows that you show improvement when you actually invest time and energy into your recovery.
Most of the patients that I’ve seen, and ones that I’ve talked to, enjoy the hands-on therapy. They enjoy the one-on-one attention they get from a provider who performs manual therapy. They enjoy that aspect a lot more than just taking a medicine that’s prescribed to them. So, I tell all my family medicine colleagues to try to think of writing a prescription for manual therapy (OMT, physical therapy, or chiropractic) instead of a prescription for medication or other interventions.
Therefore, if the prescription for physical therapy runs out, they might need a refill. Then, exactly as all providers do for medications, one can write a refill for that prescription of physical therapy. The physical aspect of chronic low back pain is just one part of the picture.
The emotional aspect is another part. We have a whole network of people to refer to in the mind/body area—psychologists, psychiatrists, and mind/body therapists—to help these patients deal with the chronicity of their pain. In addition, we attempt to empower ourselves as physicians to become more involved in the patient’s care plan. Too often, we see physicians treating low back pain with either just medications or physical therapy. However, you might not see the patient again for 6 to 8 weeks, and so much can happen in that time.
The sports medicine doctors do this very well, and they can actually write out a care plan for the patient. This goes along with the European guidelines for prevention of low back pain.26 These guidelines were released in 2004, and they group populations into 3 different groups. I’ve used a modified version of that. So, the first group is the general population dealing with low back pain, which includes the need for psychological therapy, physical therapy, and exercises and stretches.
The second group is of workers, because some people are hurt on the job and they need a specific guideline for when to go back to work and some sort of limitations that they have to maintain at work. The third group is school-age children, but I expand on this to include athletes as well. Many athletes really want a plan of action for when they can get back to a certain level in their sport. Patients can then take this plan with them and take it to their coaches.
There is a lot of one-on-one intervention that goes on when patients are dealing with a chronic injury or chronic pain. I would recommend you always make sure that you’re extending out to that network of people that you refer to. I have weekly conversations with the psychologists as well as the physical therapist that we refer patients to, to make sure that we’re all on the same page and no one’s giving overlapping advice on any treatment.
DR. RAKEL: I’ve heard from each of you about the importance of some key areas. Number one is the relationship, as Dr. Kurisu said—the quarterback, who is someone to help guide and create a plan to communicate among these different professionals to make sure we’re not overlapping treatment.
Also, it is important to match the patient to the therapy that they feel will work best for them. We’re not going to send everybody to a yoga therapist. I might not send everybody to physical therapists. If we can best match the patient’s belief system to the most appropriate team member, we will likely get a better clinical response.
Dr. Kurisu, you said it’s important when you get to know them so you can best make that match. Everybody talked about time. Let me mention the importance of laying on hands and then using the art of manual therapy to help reduce that pain and discomfort while also addressing the importance of the emotions and how internalized negative emotions might exacerbate or even trigger muscle spasm.
DR. SCHUBINER: One very important thing that I learned from you, Dr. Rakel, is that often, the majority of the therapeutic benefit results from the doctor-patient relationship. The most important ability a clinician has is the ability to listen, to take time with the patient, and to create an agreement between the doctor and the patient on defining the problem and deciding on the best form of therapy. So, I think you’re absolutely right in emphasizing that point.
DR. RAKEL: I think people get disgruntled when they perceive that they’re seeing silos of care that are just focused on a procedure or an imaging study that sees them as an object. I think everybody’s concerned about that. So I’m just going to encourage a little freedom. Any other areas that anybody wants to talk about before we finish?
DR. SCHUBINER: The other major mainstream medical approach to chronic pain comes from treatment in specialized pain clinics. Pain clinics initially arose in this country due to the widespread undertreatment of pain for people with severe pain often caused by cancer and other structural processes. The data that I’ve seen from pain programs do not typically show actual pain reduction, but rather improved coping with pain. However, I think we have shown that you can achieve significant reductions in pain. That process can only occur when we promote self-care on the part of the patient.
We have all been talking about this aspect of care. It’s promoting what the patient can do for themselves. If chronic pain is a condition of the brain, we have to help patients activate the parts of their mind, brain, and spirit that lead to healing. Healing consists of not only healing the back, but also working to heal the whole person. When we think about healing the whole person, we’re helping people to define their meaning and purpose in life. We’re promoting a deep social connection and encouraging people to align with their true selves.
DR. RAKEL: I think that’s an exciting point that you made very well, Dr. Schubiner. If I was to open a new low back pain clinic, we can change our intention from naming it the Chronic Low Back Pain Clinic to the Myofascial Health and Resiliency Clinic. That simple intention changes everything and helps the patient believe that they can get better.
DR. KING: I always appreciate it when a patient says that the work that I’ve done gives them hope. They have hope that they can get well. As soon as I hear a patient say that, I know that we’ve activated this part of their being that they need to utilize for their eventual resolution as to how “well” they can get. So, I experience an idea of what we do when giving the patient hope.
For example, we know that pain causes fear. We also know that fear causes pain. This vicious cycle is responsible for a tremendous amount of suffering. The techniques that we’re talking about can interrupt that cycle and lead to healing.
DR. RAKEL: That’s supported by the research on neuroplasticity and how we can change the brain.27 I think the most important thing I can do is convey to the patient that I believe they can get over the pain. Sometimes, they need to hear that from their health care provider. That may not always be the case, as we have to be real and truthful. But, having someone believe in their healing potential is half the journey.
DR. KURISU: Just a comment on the hope that Dr. King was talking about. Many a times, these patients have bounced around from many different pain clinics and many different specialists. The model that was presented to them is just more medications or conventional surgeries. So, when they finally get that sense of hope or finally feel that sense of empowerment, the light bulb goes on and they feel like, “Oh well, I can control this. This pain is a part of me as much as I’m a part of it. I can take these steps to help prevent this from happening.”
DR. SCHUBINER: It’s not false hope. It’s the truth, and what I always tell my patients is that “the truth will set you free.”
DR. RAKEL: Any final words anyone?
DR. KING: We have not mentioned that word “spirit” in the body–mind–spirit dimension. I think we talked around it in the mental-emotional-psychosocial aspect. This is something that I think the doctor-patient relationship, and the uniqueness of that, addresses as a relationship of one being with another being. How we operationally define that for research, is something to be seen. For the sake of our discussion, I don’t think we can avoid matters of “the spirit” or the soul. I just wanted to mention that because I think it is embodied through the approach where you’re talking to your patient and you’re putting your hands on them as all of us in the manual medicine/manual therapy will do.
DR. SCHUBINER: There is neurological research being conducted on this topic.28
When you activate social connectivity, you’re activating a sense of awe, and you’re activating the parts of the brain such as the dorsolateral prefrontal cortex that turn off the amygdala and the anterior cingulate cortex pathways that create pain. So, you’re absolutely right.
DR. RAKEL: Isn’t this a great opportunity for us to expand our strategies and research skills to look at the outcomes and the pragmatic controlled trials that ask us to determine what influences our quality of life the most? If we look at that bigger picture, we can’t help but bring up topics like meaning, belief, emotions, and spirituality. If we are going to create expertise to better understand how complex systems heal, we have to include these important ingredients.

Hysteroscopic electromechanical power morcellation
One of the hottest and most controversial topics in gynecologic surgery, at present, is laparoscopic electromechanical power morcellation.
In April of this year, the Food and Drug Administration sent out a news release regarding the potential risk of spread of sarcomatous tissue at the time of this procedure. In that release, the agency "discouraged" use of laparoscopic electromechanical power morcellation. Responses came from many societies, including the American College of Obstetricians and Gynecologists and the AAGL, which indicated that laparoscopic electromechanical power morcellation could be used if proper care was taken.
I am personally proud that the Master Class in Gynecologic Surgery has been very proactive and diligent in its discussion of laparoscopic electromechanical power morcellation. This is the third in our series regarding this topic.
In our first segment, I discussed the issue of electromechanical power morcellation relative to the inadvertent spread of sarcomatous tissue. In our second in the series, Dr. Ceana Nezhat, Dr. Bernard Taylor, and Dr. Tony Shibley discussed ways to minimize this risk – including morcellation in a bag. Videos of their individual techniques of electromechanical power morcellation, as well as that of Dr. Douglas Brown, can be viewed on SurgeryU. In addition, my partner, Dr. Aarathi Cholkeri-Singh, and I have a video on SurgeryU illustrating our technique of morcellation in a bag.
This current Master Class in Gynecologic Surgery is now devoted to hysteroscopic electromechanical power morcellation. In my discussions with physicians throughout the country relative to this technique, it has become evident that some institutions have not only banned the use of electromechanical power morcellation at time of laparoscopy, but have also stopped usage of hysteroscopic electromechanical power morcellation. While neither the FDA nor the lay press has ever questioned the use of hysteroscopic morcellators, I believe it is imperative that this topic be reviewed. I am sure that it will be obvious that hysteroscopic electromechanical power morcellation has thus far proved to be a safe and effective treatment option for various pathologic entities, including submucosal uterine fibroids.
To review hysteroscopic electromechanical power morcellation, I have invited Dr. Joseph S. Sanfilippo, professor of obstetrics, gynecology, and reproductive sciences at the University of Pittsburgh and director of the division of reproductive endocrinology and infertility at Magee-Womens Hospital in Pittsburgh.
Dr. Sanfilippo is a lecturer and educator. He has written an extensive number of peer-reviewed articles, and has been a contributor to several textbooks. In addition, Dr. Sanfilippo has been and remains a very active member of the AAGL.
It is a pleasure and honor to welcome Dr. Sanfilippo to this edition of the Master Class in Gynecologic Surgery, the third installment on morcellation.
Dr. Miller is clinical associate professor at the University of Illinois at Chicago, immediate past president of the International Society for Gynecologic Endoscopy, and a past president of the AAGL. He is a reproductive endocrinologist and minimally invasive gynecologic surgeon in private practice in Naperville, Ill., and Schaumburg, Ill.; the director of minimally invasive gynecologic surgery at Advocate Lutheran General Hospital, Park Ridge, Ill. and the medical editor of this column, Master Class. Dr. Miller disclosed that he is a consultant to Hologic and is on the speakers bureau for Smith & Nephew. Videos for this and past Master Class in Gynecology Surgery articles can be viewed on SurgeryU.

To review hysteroscopic electromechanical power morcellation, I have invited Dr. Joseph S. Sanfilippo, professor of obstetrics, gynecology, and reproductive sciences at the University of Pittsburgh and director of the division of reproductive endocrinology and infertility at Magee-Womens Hospital in Pittsburgh.
Dr. Sanfilippo is a lecturer and educator. He has written an extensive number of peer-reviewed articles, and has been a contributor to several textbooks. In addition, Dr. Sanfilippo has been and remains a very active member of the AAGL.
It is a pleasure and honor to welcome Dr. Sanfilippo to this edition of the Master Class in Gynecologic Surgery, the third installment on morcellation.
Dr. Miller is clinical associate professor at the University of Illinois at Chicago, immediate past president of the International Society for Gynecologic Endoscopy, and a past president of the AAGL. He is a reproductive endocrinologist and minimally invasive gynecologic surgeon in private practice in Naperville, Ill., and Schaumburg, Ill.; the director of minimally invasive gynecologic surgery at Advocate Lutheran General Hospital, Park Ridge, Ill. and the medical editor of this column, Master Class. Dr. Miller disclosed that he is a consultant to Hologic and is on the speakers bureau for Smith & Nephew. Videos for this and past Master Class in Gynecology Surgery articles can be viewed on SurgeryU.
One of the hottest and most controversial topics in gynecologic surgery, at present, is laparoscopic electromechanical power morcellation.
In April of this year, the Food and Drug Administration sent out a news release regarding the potential risk of spread of sarcomatous tissue at the time of this procedure. In that release, the agency "discouraged" use of laparoscopic electromechanical power morcellation. Responses came from many societies, including the American College of Obstetricians and Gynecologists and the AAGL, which indicated that laparoscopic electromechanical power morcellation could be used if proper care was taken.
I am personally proud that the Master Class in Gynecologic Surgery has been very proactive and diligent in its discussion of laparoscopic electromechanical power morcellation. This is the third in our series regarding this topic.
In our first segment, I discussed the issue of electromechanical power morcellation relative to the inadvertent spread of sarcomatous tissue. In our second in the series, Dr. Ceana Nezhat, Dr. Bernard Taylor, and Dr. Tony Shibley discussed ways to minimize this risk – including morcellation in a bag. Videos of their individual techniques of electromechanical power morcellation, as well as that of Dr. Douglas Brown, can be viewed on SurgeryU. In addition, my partner, Dr. Aarathi Cholkeri-Singh, and I have a video on SurgeryU illustrating our technique of morcellation in a bag.
This current Master Class in Gynecologic Surgery is now devoted to hysteroscopic electromechanical power morcellation. In my discussions with physicians throughout the country relative to this technique, it has become evident that some institutions have not only banned the use of electromechanical power morcellation at time of laparoscopy, but have also stopped usage of hysteroscopic electromechanical power morcellation. While neither the FDA nor the lay press has ever questioned the use of hysteroscopic morcellators, I believe it is imperative that this topic be reviewed. I am sure that it will be obvious that hysteroscopic electromechanical power morcellation has thus far proved to be a safe and effective treatment option for various pathologic entities, including submucosal uterine fibroids.
