Docs gain new flexibility treating osteoporosis from steroids
Doctors caring for patients taking steroids now have broader flexibility for which drugs to use to prevent osteoporosis associated with the medications.
The American College of Rheumatology (ACR) has released an updated guideline that advises treatment providers on when and how long to prescribe therapies that prevent or treat glucocorticoid-induced osteoporosis (GIOP). Since the ACR last updated the guideline in 2017, the Food and Drug Administration has approved new treatments for osteoporosis, which are now included in the recommendations.
The new guideline also advises physicians that they may need to transition patients to a second treatment after concluding a first course – so-called sequential therapy – to better protect them against bone loss and fracture. It also offers detailed instructions for which drugs to use, when, and how long these medications should be administered for patients taking glucocorticoids over a long period of time.
The guideline’s inclusion of sequential therapy is significant and will be helpful to practicing clinicians, according to S.B. Tanner IV, MD, director of the Osteoporosis Clinic at Vanderbilt Health, Nashville, Tenn.
“For the first time, the ACR has offered guidance for starting and stopping treatments,” Dr. Tanner said. “This guideline supports awareness that osteoporosis is lifelong – something that will consistently need monitoring.”
An estimated 2.5 million Americans use glucocorticoids, according to a 2013 study in Arthritis Care & Research. Meanwhile, a 2019 study of residents in Denmark found 3% of people in the country were prescribed glucocorticoids annually. That study estimated 54% of glucocorticoid users were female and found the percentage of people taking glucocorticoids increased with age.
Glucocorticoids are used to treat a variety of inflammatory conditions, from multiple sclerosis to lupus, and often are prescribed to transplant patients to prevent their immune systems from rejecting new organs. When taken over time these medications can cause osteoporosis, which in turn raises the risk of fracture.
More than 10% of patients who receive long-term glucocorticoid treatment are diagnosed with clinical fractures. In addition, even low-dose glucocorticoid therapy is associated with a bone loss rate of 10% per year for a patient.
Osteoporosis prevention
After stopping some prevention therapies for GIOP, a high risk of bone loss or fracture still persists, according to Linda A. Russell, MD, director of the Osteoporosis and Metabolic Bone Health Center for the Hospital for Special Surgery, New York, and co-principal investigator of the new guideline.
“We wanted to be sure the need for sequential treatment is adequately communicated, including to patients who might not know they need to start a second medication,” Dr. Russell said.
Physicians and patients must be aware that when completing a course of one GIOP treatment, another drug for the condition should be started, as specified in the guideline.
“Early intervention can prevent glucocorticoid-induced fractures that can lead to substantial morbidity and increased mortality,” said Mary Beth Humphrey, MD, PhD, interim vice president for research at the University of Oklahoma Health Sciences Center in Oklahoma City and co-principal investigator of the ACR guideline.
Janet Rubin, MD, vice chair for research in the Department of medicine at the University of North Carolina at Chapel Hill, said she is hopeful the guideline will change practice.”The risk of bone loss, fractures, and osteoporosis due to glucocorticoids has been known since the beginning of time, but the guideline reinforces the risk and treatment strategies for rheumatologists,” she said. “Such recommendations are known to influence doctor prescribing habits.”
Anyone can fracture
While age and other risk factors, including menopause, increase the risk of developing GIOP, bone loss can occur rapidly for a patient of any age.
Even a glucocorticoid dose as low as 2.5 mg will increase the risk of vertebral fractures, with some occurring as soon as 3 months after treatment starts, Dr. Humphrey said. For patients taking up to 7.5 mg daily, the risk of vertebral fracture doubles. Doses greater than 10 mg daily for more than 3 months raise the likelihood of a vertebral fracture by a factor of 14, and result in a 300% increase in the likelihood of hip fractures, according to Dr. Humphrey.
“When on steroids, even patients with high bone density scores can fracture,” Dr. Tanner said. “The 2017 guideline was almost too elaborate in its effort to calculate risk. The updated guideline acknowledges moderate risk and suggests that this is a group of patients who need treatment.”
Rank ordering adds flexibility
The updated ACR guideline no longer ranks medications based on patient fracture data, side effects, cost care, and whether the drug is provided through injection, pill, or IV.
All of the preventive treatments the panel recommends reduce the risk of steroid-induced bone loss, Dr. Humphrey said.
“We thought the 2017 guideline was too restrictive,” Dr. Russell said. “We’re giving physicians and patients more leeway to choose a medication based on their preferences.”
Patient preference of delivery mechanism – such as a desire for pills only – can now be weighed more heavily into drug treatment decisions.
“In the exam room, there are three dynamics going on: What the patient wants, what the doctor knows is most effective, and what the insurer will pay,” Dr. Tanner said. “Doing away with rank ordering opens up the conversation beyond cost to consider all those factors.”
The guideline team conducted a systematic literature review for clinical questions on nonpharmacologic and pharmacologic treatment addressed in the 2017 guideline, and for questions on new pharmacologic treatments, discontinuation of medications, and sequential and combination therapy. The voting panel consisted of two patient representatives and 13 experts representing adult and pediatric rheumatology and endocrinology, nephrology, and gastroenterology.
A full manuscript has been submitted for publication in Arthritis & Rheumatology and Arthritis Care and Research for peer review, and is expected to publish in early 2023.
Dr. Humphrey and Dr. Russell, the co-principal investigators for the guideline, and Dr. Rubin have disclosed no relevant financial relationships. Dr. Tanner reported a current research grant funded by Amgen through the University of Alabama at Birmingham and being a paid course instructor for the International Society for Clinical Densitometry bone density course, Osteoporosis Essentials.

Cell-killing cancer therapy treats lupus successfully
In a first-of-its-kind clinical trial, researchers in Germany used a cancer-killing cell therapy to successfully treat lupus in a small number of patients.
Their study, published online in Nature Medicine, included five patients with systemic lupus erythematosus (SLE). All of the patients were treated with chimeric antigen receptor (CAR) T-cell therapy, a treatment regularly used to kill cancer cells. Researchers harvested the patients’ immune cells and engineered them to destroy dysfunctional cells when infused back into the body.
The five patients – all of whom had an aggressive form of the autoimmune disease – underwent a single infusion of the experimental treatment. All five patients were able to stop their standard treatments for as long as 17 months following the therapy, the study found. The patients also stopped experiencing severe symptoms such as lung inflammation, fibrosis of the heart valves, arthritis, and fatigue. The patients have not relapsed.
“Our data reveal unexpected insights for a role of CAR T cells in nonmalignant diseases that could provide new opportunities for the treatment of autoimmune disease,” the study authors wrote.
Lupus is a chronic inflammatory disease in which the immune system attacks the body’s own cells. Both antibody-producing B and T cells in individuals with lupus become overactive, which can lead to a flare of symptoms that range from mild pain and fatigue to life-threatening inflammation and tissue damage. They are often treated with medications that deplete their B cells or change the way they function to help wipe out infected cells.
The approach used by the study researchers is similar to monoclonal antibody therapies that destroy dysfunctional B cells, such as rituximab (Rituxan and biosimilars) and obinutuzumab (Gazyva), according to Michael Belmont, MD, codirector of New York University’s Lupus Center and medical director of Bellevue Hospital Lupus Clinic, also in New York.
“Previously, this has been accomplished with monoclonal antibodies that target surface markers on B cells and results in their removal,” said Dr. Belmont, who was not connected to the study. “The report describes a novel approach that harnesses a patient’s own T cells, another type of white blood cell, to eliminate that patient’s own B cells.”
Preclinical studies involving mice previously showed that CAR T-cell therapy could help to reset the immune system. However, this latest study also found that patients did not need to continue any of their previous therapies, even after they regained their B cells about 4 months after the therapy.
“A deep depletion of CD19+ B cells and plasmablasts in the tissues could trigger an immune reset in SLE that could allow the cessation of immunosuppressive treatment,” said Mehrnaz Hojjati, MD, a rheumatologist and director of rheumatology operations at Loma Linda (Calif.) University Health. Dr. Hojjati was not affiliated with the study.
While the single-treatment therapy is promising, transfused T cells do carry risks. Some of the patients in the study experienced fever and muscle pain following the procedure, the authors noted. Dr. Belmont said more serious risks for this kind of therapy may include organ injury.
“This treatment can [also] increase incidence, for example, of pneumonia or shingles,” he said.
The study authors initially documented their work in a correspondence published in August 2021 in the New England Journal of Medicine. At that time, they reported that a 20-year-old woman with a severe refractory SLE went into remission following the treatment.
The five patients in the current study – four women and one man – were aged 18-24 years. All of the patients had previously been treated with several immunosuppressive medications, the study authors noted.
“This is an exciting approach, but many more patients need to be treated to really understand the efficacy and safety,” Dr. Belmont said.
Experts, including Dr. Belmont, also said the procedure is also costly and requires access to labs that can engineer a patient’s own T cells after they’ve been donated.
“The entire process must maintain sterility to avoid contamination, which would be harmful when reinfused into the patient,” he said.
According to Arthur Kavanaugh, MD, professor of medicine at UC San Diego Health, this form of therapy may be an option for severe refractory patients who have not responded well to other more established therapies.
“[It’s] exciting data, but very intense and so not likely to be something for an average patient in the near future,” said Dr. Kavanaugh, who was not affiliated with the study.
The study authors say they intend to create a larger trial to further explore which type of patient may benefit the most from this treatment, and for how long.
The study was supported by the German Research Foundation, the German Federal Ministry of Education and Research, the European Union, and the Innovative Medicines Initiative–funded project, Rheuma Tolerance for Cure. The study received no commercial funding, and the authors said they had no competing interests related to the study. None of the experts interviewed reported relevant financial relationships.

High iron levels predict greater fracture risk, more so in men
than matched control patients, in a large study.
Compared with control patients, those with iron overload had a roughly twofold increased risk of a vertebral fracture, as well as an increased risk of a hip or humerus fracture, but not a forearm fracture.
The increased risk of fracture in men with iron overload (compared with other matched men) was greater than the increased risk of fracture in women with iron overload (compared with other matched women).
Andrea Burden, PhD, presented the findings during a late-breaking clinical science session at the annual meeting of the American Society of Bone and Mineral Research.
‘We should worry about the bones as well as the liver’
Based on these results, clinicians should probably do earlier bone mineral density (BMD) determinations to screen for osteoporosis and perhaps consider prophylaxis with vitamin D and calcium, said Dr. Burden, assistant professor, Institute of Pharmaceutical Sciences, ETH Zürich.
“However, I say that with a bunch of caution,” she added, “because we actually don’t have much evidence of the impact of these treatment differences on fracture risk.”
“This is the first large population study on this topic,” although there have been a few case reports, Dr. Burden explained in an interview.
However, “the high iron overload of greater than 1,000 mcg/L is not common, and hereditary hemochromatosis or thalassemia also are very rare,” she noted.
“The study shows that, once patients have an iron overload of more than 1,000 mcg/L, we need to be doing regular checks for their BMD and figuring how to best minimize their fracture risk,” she said.
“A twofold risk for a vertebral fracture” in patients with iron overload “is really high,” she noted. It is known that men with iron overload have loss of testosterone, but it may be less well known that they have an increased fracture risk.
“We worry about the liver,” she said, “not so much about the bones, and this shows us that we really should.”
Session comoderator Michael J. Econs, MD, who was not involved with the research, agreed. “Iron overload does occur, and it is a clinically important problem and can lead to hemochromatosis, which can lead to a whole host of diseases, but the most common is liver disease,” he told this news organization.
“So, it is a clinically important problem, not only in people who are genetically predisposed but in people who get frequent transfusion,” said Dr. Econs, distinguished professor of medicine and medical and molecular genetics at Indiana University, Indianapolis.
Now this new study has found an increase in fractures in such people, he noted.
Large case-control study used U.K. database
Using data from the IQVIA Medical Research Database, researchers identified 21,166 iron overload patients aged 18 years and older who saw a general practitioner in the United Kingdom between 2010 and 2020 and had a serum ferritin level above 1,000 mcg/L or a diagnostic code for hemochromatosis or nonanemic thalassemia.
They matched each iron overload patient with up to 10 control patients based on age, sex, year, and general practitioner, for a total of 198,037 control patients.
Patients were a mean age of 59 years and 59% were men.
During follow-up there were 777 fractures in the iron-overload patients (9.61 fractures per 1,000 patient-years) and 4,344 fractures in the control group (4.68 fractures per 1,000 patient-years).
In adjusted hazard ratio models, researchers adjusted for age, sex, body mass index, alcohol, smoking, history of fractures earlier than 365 days prior to study entry, hypogonadism, osteoporosis, medications, and comorbidities.
Overall, patients in the iron overload group had a 60% higher risk of an osteoporotic fracture (aHR, 1.60).
Among women, the incidence of osteoporotic fracture was 12.63 per 1,000 patient-years in the iron overload group and 7.09 per 1,000 patient-years in the control group.
Women with iron overload had a 48% higher risk of osteoporotic fracture, compared with other women (aHR, 1.48).
Among men, the incidence of osteoporotic fracture was 6.71 per 1,000 patient-years in the iron overload group and 3.01 per 1,000 patient-years in the control group.
Men with iron overload therefore had an 82% higher risk of osteoporotic fracture, compared with other men (aHR, 1.82).
Compared with patients without iron overload, patients with iron overload had an increased risk of a vertebral (aHR, 2.18), hip (aHR, 1.60), and humerus (aHR, 1.82) fracture but not a forearm fracture.
The researchers acknowledge that study limitations include they did not look at phlebotomy or changes in ferritin levels, and they excluded patients with hereditary hemochromatosis diagnosed before age 18.

than matched control patients, in a large study.
Compared with control patients, those with iron overload had a roughly twofold increased risk of a vertebral fracture, as well as an increased risk of a hip or humerus fracture, but not a forearm fracture.
The increased risk of fracture in men with iron overload (compared with other matched men) was greater than the increased risk of fracture in women with iron overload (compared with other matched women).
Andrea Burden, PhD, presented the findings during a late-breaking clinical science session at the annual meeting of the American Society of Bone and Mineral Research.
‘We should worry about the bones as well as the liver’
Based on these results, clinicians should probably do earlier bone mineral density (BMD) determinations to screen for osteoporosis and perhaps consider prophylaxis with vitamin D and calcium, said Dr. Burden, assistant professor, Institute of Pharmaceutical Sciences, ETH Zürich.
“However, I say that with a bunch of caution,” she added, “because we actually don’t have much evidence of the impact of these treatment differences on fracture risk.”
“This is the first large population study on this topic,” although there have been a few case reports, Dr. Burden explained in an interview.
However, “the high iron overload of greater than 1,000 mcg/L is not common, and hereditary hemochromatosis or thalassemia also are very rare,” she noted.
“The study shows that, once patients have an iron overload of more than 1,000 mcg/L, we need to be doing regular checks for their BMD and figuring how to best minimize their fracture risk,” she said.
“A twofold risk for a vertebral fracture” in patients with iron overload “is really high,” she noted. It is known that men with iron overload have loss of testosterone, but it may be less well known that they have an increased fracture risk.
“We worry about the liver,” she said, “not so much about the bones, and this shows us that we really should.”
Session comoderator Michael J. Econs, MD, who was not involved with the research, agreed. “Iron overload does occur, and it is a clinically important problem and can lead to hemochromatosis, which can lead to a whole host of diseases, but the most common is liver disease,” he told this news organization.
“So, it is a clinically important problem, not only in people who are genetically predisposed but in people who get frequent transfusion,” said Dr. Econs, distinguished professor of medicine and medical and molecular genetics at Indiana University, Indianapolis.
Now this new study has found an increase in fractures in such people, he noted.
Large case-control study used U.K. database
Using data from the IQVIA Medical Research Database, researchers identified 21,166 iron overload patients aged 18 years and older who saw a general practitioner in the United Kingdom between 2010 and 2020 and had a serum ferritin level above 1,000 mcg/L or a diagnostic code for hemochromatosis or nonanemic thalassemia.

Lower BMI linked with better knee osteoarthritis outcomes
Losing weight and lowering body mass index may help people slow, delay, or even prevent the structural defects of knee osteoarthritis, especially on the medial side of the knee, results of a prospective multicohort study from Australia suggest.
“We showed that the more weight that is lost, the greater the apparent benefit for delaying or preventing knee joint degradation in osteoarthritis,” senior study author Amanda Sainsbury, PhD, professor of obesity research at the University of Western Australia, Perth, said in an interview. “For example, a person weighing 100 kilograms [220 pounds] who loses 10 kilograms [22 pounds] is likely to have double the benefit compared to losing 5 kilograms [11 pounds].”
“We showed evidence of association, not causality,” she and her colleagues wrote in Arthritis & Rheumatology. “Future randomized, controlled trials are required to demonstrate causality.”
Dr. Sainsbury and colleagues analyzed radiographs of knees from three independent cohort studies from the United States and the Netherlands – the Osteoarthritis Initiative (OAI), the Multicenter Osteoarthritis Study (MOST), and the Cohort Hip and Cohort Knee (CHECK) study – at baseline and again 4-5 years later.
The authors created two groups of knees at baseline: the “incidence cohort” of 9,683 knees from 5,774 participants without OA structural defects (Kellgren-Lawrence grade 0 or 1) and the “progression cohort” of 6,075 knees from 3,988 participants with OA structural defects (KL grade 2 or higher). After 4-5 years, they determined OA incidence (KL grade 2 or higher in participants without baseline knee OA) and progression (increase of one or more KL grades in those with baseline knee OA).At baseline, the mean patient age in both groups was around 60, and around 60% of participants were female. In the incidence and progression groups, respectively, White patients comprised 87.5% and 80.4% of participants; mean body mass index was 28.2 and 30.4 kg/m2; and 32.6% and 48.4% of participants were obese (BMI, 30 or higher). The authors combined data from the three studies and used logistic regression and generalized estimating equations, with clustering of both knees within individuals. On multivariable analysis, they found that change in BMI 4-5 years post baseline was positively linked with both incidence and progression of knee OA structural defects.
In the incidence group, BMI decreased 1 or more units in 1,101 patients and increased 1 or more units in 1,611. In the progression group, BMI decreased 1 or more units in 798 patients and increased in 1,008.
The adjusted odds ratio for overall structural defects in the incidence group was 1.05 (95% confidence interval, 1.02-1.09) and 1.05 (95% CI, 1.01-1.09) in the progression group was. A 1-unit decrease in BMI was linked with a nearly 5% drop in odds of incidence and progression of knee OA, and a 5-unit decrease was linked with a more than 21% drop in odds of incidence and progression.
In the incidence group, change in BMI was positively linked with medial, but not lateral, joint space degeneration (narrowing; OR, 1.08; 95% CI, 1.04-1.12) and with medial femoral surface degeneration indicated by osteophytes (OR, 1.07; 95% CI, 1.03-1.12).
In the progression group, change in BMI was positively linked with overall structural defects (OR, 1.05; 95% CI, 1.01-1.09) as well as medial, but not lateral, joint space degeneration (OR, 1.08; 95% CI, 1.03-1.12).
“Previous research showed that weight loss helps reduce symptoms of knee osteoarthritis, such as pain and impaired physical function,” said lead study author Zübeyir Salis, BEng, a PhD student in public health at the University of New South Wales, Kensington, Australia. “Weight loss is emerging as a suitable strategy for potentially delaying and preventing osteoarthritic knee joint degeneration.”
Two experts not involved in the study welcome its results
Kai Sun, MD, MS, assistant professor of medicine, rheumatology, and immunology at Duke University, Durham, N. C., said it makes mechanical sense that less weight bearing decreases knee damage over time, but she was somewhat surprised that even people who started with normal BMI improved their outcomes by decreasing BMI further.
“Knee osteoarthritis and obesity prevalence are both growing,” Dr. Sun said. “Knee osteoarthritis may one day be considered an obesity-related comorbidity like hypertension and diabetes and be used as additional justification for pharmacologic or nonpharmacologic interventions to treat obesity.”
She noted that the study’s major strengths include its large sample size, long follow-up, and separate inclusion of disease incidence and progression, but also noted some limitations.
“BMI data at only two time points does not consider BMI fluctuations between those times,” she added. “Limited data were presented on physical activity levels, and most participants being White and elderly limited the generalizability of the results.”
Eduardo Grunvald, MD, professor of medicine and medical director of the weight management program at the University of California, San Diego, agreed about the study’s strengths and pointed out its lack of information about the cause of BMI changes.
Dr. Grunvald would like to know whether the BMI changes contributed to the knee changes or vice versa. “An individual’s worsening knee pain could lead to less physical activity and possible increased BMI.
“Long-term weight-loss maintenance is extremely challenging, and for optimal outcomes, medical professionals who treat joint disease should partner with clinicians trained to treat obesity,” he advised.
The authors are planning further related research. “We’re looking forward to running a randomized, controlled clinical weight-loss trial,” Dr. Sainsbury said.The study was supported by scholarship and fellowship funds from the Australian government. Mr. Salis and Dr. Sainsbury each own 50% of shares in a company that provides educational resources and services in adult weight management. Dr. Sainsbury and one coauthor reported relevant financial relationships with various pharmaceutical companies. Dr. Sun and Dr. Grunvald reported no relevant financial relationships.

New ESC guidelines for cutting CV risk in noncardiac surgery
The European Society of Cardiology guidelines on cardiovascular assessment and management of patients undergoing noncardiac surgery have seen extensive revision since the 2014 version.
They still have the same aim – to prevent surgery-related bleeding complications, perioperative myocardial infarction/injury (PMI), stent thrombosis, acute heart failure, arrhythmias, pulmonary embolism, ischemic stroke, and cardiovascular (CV) death.
Cochairpersons Sigrun Halvorsen, MD, PhD, and Julinda Mehilli, MD, presented highlights from the guidelines at the annual congress of the European Society of Cardiology and the document was simultaneously published online in the European Heart Journal.
The document classifies noncardiac surgery into three levels of 30-day risk of CV death, MI, or stroke. Low (< 1%) risk includes eye or thyroid surgery; intermediate (1%-5%) risk includes knee or hip replacement or renal transplant; and high (> 5%) risk includes aortic aneurysm, lung transplant, or pancreatic or bladder cancer surgery (see more examples below).
It classifies patients as low risk if they are younger than 65 without CV disease or CV risk factors (smoking, hypertension, diabetes, dyslipidemia, family history); intermediate risk if they are 65 or older or have CV risk factors; and high risk if they have CVD.
In an interview, Dr. Halvorsen, professor in cardiology, University of Oslo, zeroed in on three important revisions:
First, recommendations for preoperative ECG and biomarkers are more specific, he noted.
The guidelines advise that before intermediate- or high-risk noncardiac surgery, in patients who have known CVD, CV risk factors (including age 65 or older), or symptoms suggestive of CVD:
- It is recommended to obtain a preoperative 12-lead ECG (class I).
- It is recommended to measure high-sensitivity cardiac troponin T (hs-cTn T) or high-sensitivity cardiac troponin I (hs-cTn I). It is also recommended to measure these biomarkers at 24 hours and 48 hours post surgery (class I).
- It should be considered to measure B-type natriuretic peptide or N-terminal of the prohormone BNP (NT-proBNP).
However, for low-risk patients undergoing low- and intermediate-risk noncardiac surgery, it is not recommended to routinely obtain preoperative ECG, hs-cTn T/I, or BNP/NT-proBNP concentrations (class III).
Troponins have a stronger class I recommendation, compared with the IIA recommendation for BNP, because they are useful for preoperative risk stratification and for diagnosis of PMI, Dr. Halvorsen explained. “Patients receive painkillers after surgery and may have no pain,” she noted, but they may have PMI, which has a bad prognosis.
Second, the guidelines recommend that “all patients should stop smoking 4 weeks before noncardiac surgery [class I],” she noted. Clinicians should also “measure hemoglobin, and if the patient is anemic, treat the anemia.”
Third, the sections on antithrombotic treatment have been significantly revised. “Bridging – stopping an oral antithrombotic drug and switching to a subcutaneous or IV drug – has been common,” Dr. Halvorsen said, “but recently we have new evidence that in most cases that increases the risk of bleeding.”
“We are [now] much more restrictive with respect to bridging” with unfractionated heparin or low-molecular-weight heparin, she said. “We recommend against bridging in patients with low to moderate thrombotic risk,” and bridging should only be considered in patients with mechanical prosthetic heart valves or with very high thrombotic risk.
More preoperative recommendations
In the guideline overview session at the congress, Dr. Halverson highlighted some of the new recommendations for preoperative risk assessment.
If time allows, it is recommended to optimize guideline-recommended treatment of CVD and control of CV risk factors including blood pressure, dyslipidemia, and diabetes, before noncardiac surgery (class I).
Patients commonly have “murmurs, chest pain, dyspnea, and edema that may suggest severe CVD, but may also be caused by noncardiac disease,” she noted. The guidelines state that “for patients with a newly detected murmur and symptoms or signs of CVD, transthoracic echocardiography is recommended before noncardiac surgery (class I).
“Many studies have been performed to try to find out if initiation of specific drugs before surgery could reduce the risk of complications,” Dr. Halvorsen noted. However, few have shown any benefit and “the question of presurgery initiation of beta-blockers has been greatly debated,” she said. “We have again reviewed the literature and concluded ‘Routine initiation of beta-blockers perioperatively is not recommended (class IIIA).’ “
“We adhere to the guidelines on acute and chronic coronary syndrome recommending 6-12 months of dual antiplatelet treatment as a standard before elective surgery,” she said. “However, in case of time-sensitive surgery, the duration of that treatment can be shortened down to a minimum of 1 month after elective PCI and a minimum of 3 months after PCI and ACS.”
Patients with specific types of CVD
Dr. Mehilli, a professor at Landshut-Achdorf (Germany) Hospital, highlighted some new guideline recommendations for patients who have specific types of cardiovascular disease.
Coronary artery disease (CAD). “For chronic coronary syndrome, a cardiac workup is recommended only for patients undergoing intermediate risk or high-risk noncardiac surgery.”
“Stress imaging should be considered before any high risk, noncardiac surgery in asymptomatic patients with poor functional capacity and prior PCI or coronary artery bypass graft (new recommendation, class IIa).”
Mitral valve regurgitation. For patients undergoing scheduled noncardiac surgery, who remain symptomatic despite guideline-directed medical treatment for mitral valve regurgitation (including resynchronization and myocardial revascularization), consider a valve intervention – either transcatheter or surgical – before noncardiac surgery in eligible patients with acceptable procedural risk (new recommendation).
Cardiac implantable electronic devices (CIED). For high-risk patients with CIEDs undergoing noncardiac surgery with high probability of electromagnetic interference, a CIED checkup and necessary reprogramming immediately before the procedure should be considered (new recommendation).
Arrhythmias. “I want only to stress,” Dr. Mehilli said, “in patients with atrial fibrillation with acute or worsening hemodynamic instability undergoing noncardiac surgery, an emergency electrical cardioversion is recommended (class I).”
Peripheral artery disease (PAD) and abdominal aortic aneurysm. For these patients “we do not recommend a routine referral for a cardiac workup. But we recommend it for patients with poor functional capacity or with significant risk factors or symptoms (new recommendations).”
Chronic arterial hypertension. “We have modified the recommendation, recommending avoidance of large perioperative fluctuations in blood pressure, and we do not recommend deferring noncardiac surgery in patients with stage 1 or 2 hypertension,” she said.
Postoperative cardiovascular complications
The most frequent postoperative cardiovascular complication is PMI, Dr. Mehilli noted.
“In the BASEL-PMI registry, the incidence of this complication around intermediate or high-risk noncardiac surgery was up to 15% among patients older than 65 years or with a history of CAD or PAD, which makes this kind of complication really important to prevent, to assess, and to know how to treat.”
“It is recommended to have a high awareness for perioperative cardiovascular complications, combined with surveillance for PMI in patients undergoing intermediate- or high-risk noncardiac surgery” based on serial measurements of high-sensitivity cardiac troponin.
The guidelines define PMI as “an increase in the delta of high-sensitivity troponin more than the upper level of normal,” Dr. Mehilli said. “It’s different from the one used in a rule-in algorithm for non-STEMI acute coronary syndrome.”
Postoperative atrial fibrillation (AFib) is observed in 2%-30% of noncardiac surgery patients in different registries, particularly in patients undergoing intermediate or high-risk noncardiac surgery, she noted.
“We propose an algorithm on how to prevent and treat this complication. I want to highlight that in patients with hemodynamic unstable postoperative AF[ib], an emergency cardioversion is indicated. For the others, a rate control with the target heart rate of less than 110 beats per minute is indicated.”
In patients with postoperative AFib, long-term oral anticoagulation therapy should be considered in all patients at risk for stroke, considering the anticipated net clinical benefit of oral anticoagulation therapy as well as informed patient preference (new recommendations).
Routine use of beta-blockers to prevent postoperative AFib in patients undergoing noncardiac surgery is not recommended.
The document also covers the management of patients with kidney disease, diabetes, cancer, obesity, and COVID-19. In general, elective noncardiac surgery should be postponed after a patient has COVID-19, until he or she recovers completely, and coexisting conditions are optimized.
The guidelines are available from the ESC website in several formats: pocket guidelines, pocket guidelines smartphone app, guidelines slide set, essential messages, and the European Heart Journal article.
Noncardiac surgery risk categories
The guideline includes a table that classifies noncardiac surgeries into three groups, based on the associated 30-day risk of death, MI, or stroke:
- Low (< 1%): breast, dental, eye, thyroid, and minor gynecologic, orthopedic, and urologic surgery.
- Intermediate (1%-5%): carotid surgery, endovascular aortic aneurysm repair, gallbladder surgery, head or neck surgery, hernia repair, peripheral arterial angioplasty, renal transplant, major gynecologic, orthopedic, or neurologic (hip or spine) surgery, or urologic surgery
- High (> 5%): aortic and major vascular surgery (including aortic aneurysm), bladder removal (usually as a result of cancer), limb amputation, lung or liver transplant, pancreatic surgery, or perforated bowel repair.
The guidelines were endorsed by the European Society of Anaesthesiology and Intensive Care. The guideline authors reported numerous disclosures.

The European Society of Cardiology guidelines on cardiovascular assessment and management of patients undergoing noncardiac surgery have seen extensive revision since the 2014 version.
They still have the same aim – to prevent surgery-related bleeding complications, perioperative myocardial infarction/injury (PMI), stent thrombosis, acute heart failure, arrhythmias, pulmonary embolism, ischemic stroke, and cardiovascular (CV) death.
Cochairpersons Sigrun Halvorsen, MD, PhD, and Julinda Mehilli, MD, presented highlights from the guidelines at the annual congress of the European Society of Cardiology and the document was simultaneously published online in the European Heart Journal.
The document classifies noncardiac surgery into three levels of 30-day risk of CV death, MI, or stroke. Low (< 1%) risk includes eye or thyroid surgery; intermediate (1%-5%) risk includes knee or hip replacement or renal transplant; and high (> 5%) risk includes aortic aneurysm, lung transplant, or pancreatic or bladder cancer surgery (see more examples below).
It classifies patients as low risk if they are younger than 65 without CV disease or CV risk factors (smoking, hypertension, diabetes, dyslipidemia, family history); intermediate risk if they are 65 or older or have CV risk factors; and high risk if they have CVD.
In an interview, Dr. Halvorsen, professor in cardiology, University of Oslo, zeroed in on three important revisions:
First, recommendations for preoperative ECG and biomarkers are more specific, he noted.
The guidelines advise that before intermediate- or high-risk noncardiac surgery, in patients who have known CVD, CV risk factors (including age 65 or older), or symptoms suggestive of CVD:
- It is recommended to obtain a preoperative 12-lead ECG (class I).
- It is recommended to measure high-sensitivity cardiac troponin T (hs-cTn T) or high-sensitivity cardiac troponin I (hs-cTn I). It is also recommended to measure these biomarkers at 24 hours and 48 hours post surgery (class I).
- It should be considered to measure B-type natriuretic peptide or N-terminal of the prohormone BNP (NT-proBNP).
However, for low-risk patients undergoing low- and intermediate-risk noncardiac surgery, it is not recommended to routinely obtain preoperative ECG, hs-cTn T/I, or BNP/NT-proBNP concentrations (class III).
Troponins have a stronger class I recommendation, compared with the IIA recommendation for BNP, because they are useful for preoperative risk stratification and for diagnosis of PMI, Dr. Halvorsen explained. “Patients receive painkillers after surgery and may have no pain,” she noted, but they may have PMI, which has a bad prognosis.
Second, the guidelines recommend that “all patients should stop smoking 4 weeks before noncardiac surgery [class I],” she noted. Clinicians should also “measure hemoglobin, and if the patient is anemic, treat the anemia.”
Third, the sections on antithrombotic treatment have been significantly revised. “Bridging – stopping an oral antithrombotic drug and switching to a subcutaneous or IV drug – has been common,” Dr. Halvorsen said, “but recently we have new evidence that in most cases that increases the risk of bleeding.”
“We are [now] much more restrictive with respect to bridging” with unfractionated heparin or low-molecular-weight heparin, she said. “We recommend against bridging in patients with low to moderate thrombotic risk,” and bridging should only be considered in patients with mechanical prosthetic heart valves or with very high thrombotic risk.

Autoimmune diseases linked to spike in post-MI events
, in a large propensity-matched analysis.
At a median of 2 years after their MI, Medicare beneficiaries with an IMID had adjusted risks that were:
- 15% higher for all-cause death (hazard ratio, 1.15);
- 12% higher for heart failure (HR, 1.12);
- 8% higher for recurrent MI (HR, 1.08); and
- 6% higher risk for coronary reintervention (HR, 1.06; P < .05 for all).
In addition, interventions known to improve outcomes in this context, such as coronary revascularization, were less common in patients with IMID.
“This could be because they usually are sicker and have more risk factors when they present, like kidney disease, so maybe they’re not eligible for the therapy. But by itself, it was surprising they’re not offered these interventions as common[ly] as people who don’t have the disease,” Amgad Mentias, MD, a clinical cardiologist at the Cleveland Clinic, said in an interview.
The study was published Sept. 14 in the Journal of the American Heart Association, with Dr. Mentias as senior author and Heba Wassif, MD, MPH, also with Cleveland Clinic, as first author.
IMIDs, such as rheumatoid arthritis, psoriasis, lupus, and inflammatory bowel disease, are known to be associated with significantly higher cardiovascular disease (CVD) risk due to a greater prevalence of traditional CVD risk factors and chronic systemic inflammation.
Certain disease-modifying agents may also increase patients’ cardiovascular risk. This has been a long-simmering issue for the arthritis and ulcerative colitis drug tofacitinib (Xeljanz, Xeljanz XR), resulting in an updated boxed warning in 2021.
Many of these patients also have joint disease, pain, and fatigue, which can limit physical activity, Dr. Mentias said. “So these small nuances of how to manage these patients, or balance between controlling the inflammation but also improv[ing] cardiac risk factors, is not an easy task.”
Evidence regarding post-MI events has been inconsistent and limited to smaller single-center studies, he said. After propensity-score matching, the present study included 59,820 patients with and 178,547 patients without rheumatic IMIDs followed for a maximum of 6 years.
They were drawn from a cohort of 1.6 million persons aged 65 or older in the Medicare Provider Analysis and Review (MedPAR) file who had been admitted for an MI between 2014 and 2019. Of these, 60,072 had a prior history of rheumatic IMIDs, most commonly rheumatoid arthritis (77.8%), followed by systemic lupus erythematosus (12.2%), psoriasis (5.1%), systemic sclerosis (2.8%), and myositis/dermatomyositis (1.8%).
Patients with an IMID were more often women; had a higher prevalence of valve disease, pulmonary hypertension, hypothyroidism, and anemia; and were more likely to present with non–ST-segment MI (NSTEMI).
Rates of coronary angiography (46.1% vs. 51.5%), percutaneous coronary intervention (31.6% vs. 33.6%), and coronary artery bypass grafting (7.7% vs. 10.7%) were significantly lower in patients with IMIDs who had NSTEMI, compared with patients without an IMID who had NSTEMI. Rates of these interventions were also lower in patients with IMIDs who presented with STEMI versus their peers without an IMID, at 78.2% vs. 80.7%, 70.2% vs. 71.5%, and 4.9% vs. 6.4%, respectively.
Dr. Mentias pointed out that the emerging subspecialty of cardiorheumatology is gaining traction, especially at large hospitals and academic centers, but that less than one-third of persons in the United States with an IMID are likely to be under the care of such specialists.
“It’s important before developing an MI to try and control the different risk factors and improve the risk profile for these patients as much as possible by both specialties, and then, after an unfortunate event like MI happens, it’s important to make sure we offer therapies and treatments that are known to improve outcomes,” he said.
Commenting for this article, Jon Tyler Giles, MD, a clinical researcher who focuses on cardiovascular diseases in rheumatology at Columbia University Vagelos College of Physicians and Surgeons, New York, said that “at least for rheumatoid arthritis, this is something that we already knew. People with rheumatic arthritis, when they have a heart attack, are less likely to get the standard kind of treatments and have worse outcomes. This is a little larger sample, but it’s not a surprise, not a surprise at all.”
He noted that the study could have answered questions regarding potential drivers, but “they didn’t dig down into any of the factors that were associated with the poorer outcomes in the patients with rheumatoid arthritis and lupus and scleroderma.”
Indeed, the investigators acknowledge that the study lacked information on coronary anatomy, duration and severity of the autoimmune disease, imaging data, and medications such as anti-inflammatory or immune-targeted therapies.
Dr. Giles highlighted several factors that can contribute to a poorer post-MI prognosis in patients with rheumatic diseases; these include frailty, being more hypercoaguable, increased rates of myocardial dysfunction and other heart and blood vessel diseases, and chronic treatment with steroids and nonsteroidal anti-inflammatory drugs that often interferes with anticoagulation after a MI or when putting in a stent. “So, there’s lot of moving parts, and not one single thing that is likely the answer.”
In addition, he said, “there’s always going to be a portion of these patients who, despite doing the best that we can with treatment, are going to have very severe disease. That may or may not be the subset of patients that did the worst, but likely they’re overrepresented in those patients.”
Finally, the inability to move the needle may lie with the lack of evidence-based screening and management guidelines for cardiovascular disease in any rheumatic disease, Dr. Giles observed. “There’s no guideline for us to use to decide who needs screening over and above what’s recommended for the general population, and then, even if you do screen, what do you do other than what you would normally?”
Rheumatologists are often reluctant to take up the cardiovascular screening side of things because visits are short, and a lot of that time is spent trying to manage the inflammatory components of a patient’s disease, he said. There’s also a barrier in getting some patients to add a cardiologist to the mix of physicians they already see, especially if they don’t have any symptoms.
“If someone has had an event, it’s a lot easier for people to be convinced to go see the cardiologist, obviously, but prior to having an event, the preventative side of things is something that often gets missed or goes to the wayside,” Dr. Giles said.
The study was partly funded by philanthropic gifts by the Haslam family, Bailey family, and Khouri family to the Cleveland Clinic for coauthor Dr. Milind Desai’s research. Dr. Desai is a consultant for Medtronic and Bristol Myers Squibb and serves on an executive steering committee of a BMS-sponsored trial. The remaining authors report having no relevant disclosures. Dr. Giles is a consultant on drug cardiovascular safety for Pfizer, AbbVie, and Eli Lilly.

Of these, 60,072 had a prior history of rheumatic IMIDs, most commonly rheumatoid arthritis (77.8%), followed by systemic lupus erythematosus (12.2%), psoriasis (5.1%), systemic sclerosis (2.8%), and myositis/dermatomyositis (1.8%).
Patients with an IMID were more often women; had a higher prevalence of valve disease, pulmonary hypertension, hypothyroidism, and anemia; and were more likely to present with non–ST-segment MI (NSTEMI).
Rates of coronary angiography (46.1% vs. 51.5%), percutaneous coronary intervention (31.6% vs. 33.6%), and coronary artery bypass grafting (7.7% vs. 10.7%) were significantly lower in patients with IMIDs who had NSTEMI, compared with patients without an IMID who had NSTEMI. Rates of these interventions were also lower in patients with IMIDs who presented with STEMI versus their peers without an IMID, at 78.2% vs. 80.7%, 70.2% vs. 71.5%, and 4.9% vs. 6.4%, respectively.
Dr. Mentias pointed out that the emerging subspecialty of cardiorheumatology is gaining traction, especially at large hospitals and academic centers, but that less than one-third of persons in the United States with an IMID are likely to be under the care of such specialists.
“It’s important before developing an MI to try and control the different risk factors and improve the risk profile for these patients as much as possible by both specialties, and then, after an unfortunate event like MI happens, it’s important to make sure we offer therapies and treatments that are known to improve outcomes,” he said.
Commenting for this article, Jon Tyler Giles, MD, a clinical researcher who focuses on cardiovascular diseases in rheumatology at Columbia University Vagelos College of Physicians and Surgeons, New York, said that “at least for rheumatoid arthritis, this is something that we already knew. People with rheumatic arthritis, when they have a heart attack, are less likely to get the standard kind of treatments and have worse outcomes. This is a little larger sample, but it’s not a surprise, not a surprise at all.”
He noted that the study could have answered questions regarding potential drivers, but “they didn’t dig down into any of the factors that were associated with the poorer outcomes in the patients with rheumatoid arthritis and lupus and scleroderma.”
Indeed, the investigators acknowledge that the study lacked information on coronary anatomy, duration and severity of the autoimmune disease, imaging data, and medications such as anti-inflammatory or immune-targeted therapies.
Dr. Giles highlighted several factors that can contribute to a poorer post-MI prognosis in patients with rheumatic diseases; these include frailty, being more hypercoaguable, increased rates of myocardial dysfunction and other heart and blood vessel diseases, and chronic treatment with steroids and nonsteroidal anti-inflammatory drugs that often interferes with anticoagulation after a MI or when putting in a stent. “So, there’s lot of moving parts, and not one single thing that is likely the answer.”
In addition, he said, “there’s always going to be a portion of these patients who, despite doing the best that we can with treatment, are going to have very severe disease. That may or may not be the subset of patients that did the worst, but likely they’re overrepresented in those patients.”
Finally, the inability to move the needle may lie with the lack of evidence-based screening and management guidelines for cardiovascular disease in any rheumatic disease, Dr. Giles observed. “There’s no guideline for us to use to decide who needs screening over and above what’s recommended for the general population, and then, even if you do screen, what do you do other than what you would normally?”
Rheumatologists are often reluctant to take up the cardiovascular screening side of things because visits are short, and a lot of that time is spent trying to manage the inflammatory components of a patient’s disease, he said. There’s also a barrier in getting some patients to add a cardiologist to the mix of physicians they already see, especially if they don’t have any symptoms.
“If someone has had an event, it’s a lot easier for people to be convinced to go see the cardiologist, obviously, but prior to having an event, the preventative side of things is something that often gets missed or goes to the wayside,” Dr. Giles said.
The study was partly funded by philanthropic gifts by the Haslam family, Bailey family, and Khouri family to the Cleveland Clinic for coauthor Dr. Milind Desai’s research. Dr. Desai is a consultant for Medtronic and Bristol Myers Squibb and serves on an executive steering committee of a BMS-sponsored trial. The remaining authors report having no relevant disclosures.

, in a large propensity-matched analysis.
At a median of 2 years after their MI, Medicare beneficiaries with an IMID had adjusted risks that were:
- 15% higher for all-cause death (hazard ratio, 1.15);
- 12% higher for heart failure (HR, 1.12);
- 8% higher for recurrent MI (HR, 1.08); and
- 6% higher risk for coronary reintervention (HR, 1.06; P < .05 for all).
In addition, interventions known to improve outcomes in this context, such as coronary revascularization, were less common in patients with IMID.
“This could be because they usually are sicker and have more risk factors when they present, like kidney disease, so maybe they’re not eligible for the therapy. But by itself, it was surprising they’re not offered these interventions as common[ly] as people who don’t have the disease,” Amgad Mentias, MD, a clinical cardiologist at the Cleveland Clinic, said in an interview.
The study was published Sept. 14 in the Journal of the American Heart Association, with Dr. Mentias as senior author and Heba Wassif, MD, MPH, also with Cleveland Clinic, as first author.
IMIDs, such as rheumatoid arthritis, psoriasis, lupus, and inflammatory bowel disease, are known to be associated with significantly higher cardiovascular disease (CVD) risk due to a greater prevalence of traditional CVD risk factors and chronic systemic inflammation.
Certain disease-modifying agents may also increase patients’ cardiovascular risk. This has been a long-simmering issue for the arthritis and ulcerative colitis drug tofacitinib (Xeljanz, Xeljanz XR), resulting in an updated boxed warning in 2021.
Many of these patients also have joint disease, pain, and fatigue, which can limit physical activity, Dr. Mentias said. “So these small nuances of how to manage these patients, or balance between controlling the inflammation but also improv[ing] cardiac risk factors, is not an easy task.”

Fish oil pills do not reduce fractures in healthy seniors: VITAL
Omega-3 supplements did not reduce fractures during a median 5.3-year follow-up in the more than 25,000 generally healthy men and women (≥ age 50 and ≥ age 55, respectively) in the Vitamin D and Omega-3 Trial (VITAL).
The large randomized controlled trial tested whether omega-3 fatty acid or vitamin D supplements prevented cardiovascular disease or cancer in a representative sample of midlife and older adults from 50 U.S. states – which they did not. In a further analysis of VITAL, vitamin D supplements (cholecalciferol, 2,000 IU/day) did not lower the risk of incident total, nonvertebral, and hip fractures, compared with placebo.
Now this new analysis shows that omega-3 fatty acid supplements (1 g/day of fish oil) did not reduce the risk of such fractures in the VITAL population either. Meryl S. LeBoff, MD, presented the latest findings during an oral session at the annual meeting of the American Society for Bone and Mineral Research.
“In this, the largest randomized controlled trial in the world, we did not find an effect of omega-3 fatty acid supplements on fractures,” Dr. LeBoff, from Brigham and Women’s Hospital and Harvard Medical School, both in Boston, told this news organization.
The current analysis did “unexpectedly” show that among participants who received the omega-3 fatty acid supplements, there was an increase in fractures in men, and fracture risk was higher in people with a normal or low body mass index and lower in people with higher BMI.
However, these subgroup findings need to be interpreted with caution and may be caused by chance, Dr. LeBoff warned. The researchers will be investigating these findings in further analyses.
Should patients take omega-3 supplements or not?
Asked whether, in the meantime, patients should start or keep taking fish oil supplements for possible health benefits, she noted that certain individuals might benefit.
For example, in VITAL, participants who ate less than 1.5 servings of fish per week and received omega-3 fatty acid supplements had a decrease in the combined cardiovascular endpoint, and Black participants who took fish oil supplements had a substantially reduced risk of the outcome, regardless of fish intake.
“I think everybody needs to review [the study findings] with clinicians and make a decision in terms of what would be best for them,” she said.
Session comoderator Bente Langdahl, MD, PhD, commented that “many people take omega-3 because they think it will help” knee, hip, or other joint pain.
Perhaps men are more prone to joint pain because of osteoarthritis and the supplements lessen the pain, so these men became more physically active and more prone to fractures, she speculated.
The current study shows that, “so far, we haven’t been able to demonstrate a reduced rate of fractures with fish oil supplements in clinical randomized trials” conducted in relatively healthy and not the oldest patients, she summarized. “We’re not talking about 80-year-olds.”
In this “well-conducted study, they were not able to see any difference” with omega-3 fatty acid supplements versus placebo, but apparently, there are no harms associated with taking these supplements, she said.
To patients who ask her about such supplements, Dr. Langdahl advised: “Try it out for 3 months. If it really helps you, if it takes away your joint pain or whatever, then that might work for you. But then remember to stop again because it might just be a temporary effect.”
Could fish oil supplements protect against fractures?
An estimated 22% of U.S. adults aged 60 and older take omega-3 fatty acid supplements, Dr. LeBoff noted.
Preclinical studies have shown that omega-3 fatty acids reduce bone resorption and have anti-inflammatory effects, but observational studies have reported conflicting findings.
The researchers conducted this ancillary study of VITAL to fill these knowledge gaps.
VITAL enrolled a national sample of 25,871 U.S. men and women, including 5,106 Black participants, with a mean age of 67 and a mean BMI of 28 kg/m2.
Importantly, participants were not recruited by low bone density, fractures, or vitamin D deficiency. Prior to entry, participants were required to stop taking omega-3 supplements and limit nonstudy vitamin D and calcium supplements.
The omega-3 fatty acid supplements used in the study contained eicosapentaenoic acid and docosahexaenoic acid in a 1.2:1 ratio.
VITAL had a 2x2 factorial design whereby 6,463 participants were randomized to receive the omega-3 fatty acid supplement and 6,474 were randomized to placebo. (Remaining participants were randomized to receive vitamin D or placebo.)
Participants in the omega-3 fatty acid and placebo groups had similar baseline characteristics. For example, about half (50.5%) were women, and on average, they ate 1.1 servings of dark-meat fish (such as salmon) per week.
Participants completed detailed questionnaires at baseline and each year.
Plasma omega-3 levels were measured at baseline and, in 1,583 participants, at 1 year of follow-up. The mean omega-3 index rose 54.7% in the omega-3 fatty acid group and changed less than 2% in the placebo group at 1 year.
Study pill adherence was 87.0% at 2 years and 85.7% at 5 years.
Fractures were self-reported on annual questionnaires and centrally adjudicated in medical record review.
No clinically meaningful effect of omega-3 fatty acids on fractures
During a median 5.3-year follow-up, researchers adjudicated 2,133 total fractures and confirmed 1,991 fractures (93%) in 1551 participants.
Incidences of total, nonvertebral, and hip fractures were similar in both groups.
Compared with placebo, omega-3 fatty acid supplements had no significant effect on risk of total fractures (hazard ratio, 1.02; 95% confidence interval, 0.92-1.13), nonvertebral fractures (HR, 1.01; 95% CI, 0.91-1.12), or hip fractures (HR, 0.89; 95% CI, 0.61-1.30), all adjusted for age, sex, and race.
The “confidence intervals were narrow, likely excluding a clinically meaningful effect,” Dr. LeBoff noted.
Among men, those who received fish oil supplements had a greater risk of fracture than those who received placebo (HR, 1.27; 95% CI, 1.07-1.51), but this result “was not corrected for multiple hypothesis testing,” Dr. LeBoff cautioned.
In the overall population, participants with a BMI less than 25 who received fish oil versus placebo had an increased risk of fracture, and those with a BMI of at least 30 who received fish oil versus placebo had a decreased risk of fracture, but the limits of the confidence intervals crossed 1.00.
After excluding digit, skull, and pathologic fractures, there was no significant reduction in total fractures (HR, 1.02; 95% CI, 0.92-1.14), nonvertebral fractures (HR, 1.02; 95% CI, 0.92-1.14), or hip fractures (HR, 0.90; 95% CI, 0.61-1.33), with omega-3 supplements versus placebo.
Similarly, there was no significant reduction in risk of major osteoporotic fractures (hip, wrist, humerus, and clinical spine fractures) or wrist fractures with omega-3 supplements versus placebo.
VITAL only studied one dose of omega-3 fatty acid supplements, and results may not be generalizable to younger adults, or older adults living in residential communities, Dr. LeBoff noted.
The study was supported by grants from the National Institute of Arthritis Musculoskeletal and Skin Diseases. VITAL was funded by the National Cancer Institute and the National Heart, Lung, and Blood Institute. Dr. LeBoff and Dr. Langdahl have reported no relevant financial relationships.

Among men, those who received fish oil supplements had a greater risk of fracture than those who received placebo (HR, 1.27; 95% CI, 1.07-1.51), but this result “was not corrected for multiple hypothesis testing,” Dr. LeBoff cautioned.
In the overall population, participants with a BMI less than 25 who received fish oil versus placebo had an increased risk of fracture, and those with a BMI of at least 30 who received fish oil versus placebo had a decreased risk of fracture, but the limits of the confidence intervals crossed 1.00.
After excluding digit, skull, and pathologic fractures, there was no significant reduction in total fractures (HR, 1.02; 95% CI, 0.92-1.14), nonvertebral fractures (HR, 1.02; 95% CI, 0.92-1.14), or hip fractures (HR, 0.90; 95% CI, 0.61-1.33), with omega-3 supplements versus placebo.
Similarly, there was no significant reduction in risk of major osteoporotic fractures (hip, wrist, humerus, and clinical spine fractures) or wrist fractures with omega-3 supplements versus placebo.
VITAL only studied one dose of omega-3 fatty acid supplements, and results may not be generalizable to younger adults, or older adults living in residential communities, Dr. LeBoff noted.
The study was supported by grants from the National Institute of Arthritis Musculoskeletal and Skin Diseases. VITAL was funded by the National Cancer Institute and the National Heart, Lung, and Blood Institute. Dr. LeBoff and Dr. Langdahl have reported no relevant financial relationships.

Possible sex differences found in response to first treatments for early RA
Men with early rheumatoid arthritis who had previously never been treated with disease-modifying antirheumatic drugs (DMARDs) achieved remission significantly more often than women when given the interleukin (IL)-6 inhibitor tocilizumab (Actemra), according to new findings published in The Lancet Rheumatology.
Researchers also found that men had higher rates of remission than women when treated with certolizumab pegol (Cimzia), abatacept (Orencia), or conventional synthetic DMARDs, but the differences were not statistically significant.
The findings are based on a post-hoc analysis of data from the randomized, controlled, phase 4 NORD-STAR trial performed across Scandinavia, Iceland, and the Netherlands that is believed to be the first study on treatment-naive patients to specifically analyze the interaction between sex and treatment using interaction terms. In the study, outcomes for men versus women were compared within each treatment group and also to the conventional treatment arm used as the reference group.
“Our findings could provide guidance about the optimal treatment choice for DMARD-naive men and women with early RA,” said first author Kristina Lend, MSc, research assistant at the Karolinska Institute, Stockholm, and PhD student at Amsterdam University Medical Center.
Researchers enrolled 812 patients between 2012 and 2018 and randomly assigned them to receive:
- Conventional treatment involving methotrexate plus prednisolone tapered from 20 mg per day to 5 mg per day within 9 weeks or methotrexate plus sulfasalazine (2 g per day), hydroxychloroquine (35 mg/kg per week or 200 mg per day), and intra-articular glucocorticoids in the swollen joint (maximally four joints and 80 mg per visit);
- the tumor necrosis factor (TNF) inhibitor certolizumab pegol with methotrexate;
- the T-cell co-stimulation modulator abatacept with methotrexate; or
- tocilizumab with methotrexate.
All of the patients were newly diagnosed, with symptoms for less than 24 months, and they had never taken a DMARD. Researchers used the Clinical Disease Activity Index (CDAI) as the primary tool for assessing remission. Patients started oral methotrexate initially at 10-15 mg per week and escalated within 4 weeks to a target dose of 25 mg per week.
In all groups, men achieved remission after 24 weeks at higher rates than women: 55% compared with 50% in the conventional arm; 57% vs. 52% with certolizumab pegol; 65% vs. 51% with abatacept; and 61% vs. 40% with tocilizumab. But in most cases, the 95% confidence intervals overlapped for men and women, meaning the differences didn’t reach statistical significance.
However, in the tocilizumab group, the difference was significant.
Ms. Lend said it was interesting to see this difference with tocilizumab. The drug is known to reduce acute-phase reactants, such as C-reactive protein (CRP). But the CDAI doesn’t take CRP or other acute phase reactants into account. Both men and women taking tocilizumab had significant reductions in CRP, and yet men ultimately did much better on the drug according to the CDAI, as well as other scales, such as the Disease Activity Score in 28 joints and Simplified Disease Activity Index.
Women in the conventional treatment arm actually achieved remission more often, at least in absolute numbers, than did women taking tocilizumab.
“It was surprising to see that men on tocilizumab treatment achieved higher remission rates than men in conventional treatment while women in tocilizumab treatment achieved lower remission rates than women in conventional treatment,” she said.
Several factors could account for the differences in remission, she said. Subjective components when assessing remission – such as tender joint counts and a patient’s own assessment of their disease activity – tend to be higher for women. Underlying biological mechanisms can play a role as well, with evidence suggesting that gonadal hormone concentrations modulate the immune system and affect pain signaling, influencing how the disease is experienced, she said.
Findings such as these could lead to a redrafting of treatment recommendations, Ms. Lend suggested.
“Conventional treatment is currently recommended over tocilizumab and other biologics for DMARD-naive men and women with early RA,” she said. “We do feel that the overall results of the NORD-STAR trial could lead to a reassessment of these recommendations, and that more personalized treatment decisions will become the standard.”
In an accompanying editorial, Alexandre Sepriano, MD, PhD, a rheumatologist at Hospital Egaz Moniz in Lisbon, and Elena Nikiphorou, MD, consultant rheumatologist at King’s College London, said the analysis was generally well-designed, although perhaps too small.
“The NORD-STAR trial, compared to other studies, comes the closest to answering the question at hand,” they wrote. “A fair conclusion is that (with the exception of tocilizumab) men and women respond similarly to biological DMARDs compared with conventional therapy. If true, this is reassuring news both to patients and clinicians.”
They cautioned that the study was “probably underpowered” to answer the question authoritatively.
“Despite this, the study provides useful insights into sex-driven responses to treatment,” they said. “Differences in methodological and analytical approaches will need to be considered in studies with similar intentions when interpreting the findings.”
Ruth Fritsch-Stork, MD, PhD, professor of rheumatology at Sigmund Freud University in Vienna, who has studied sex and RA treatment in the Austrian BIOREG registry, said the findings are an important contribution to the literature.
“I think it is a very interesting paper, as little literature has been published about sex differences in RA patients regarding therapy,” she said. “And the little that is known is ambiguous. So this paper is a badly needed piece in the puzzle of treatment response in RA.”
She said she wondered how much these findings will be applicable to typical clinical scenarios, in which tocilizumab is usually at least a second-line therapy, after use of conventional synthetic DMARDs – and often after anti-TNF therapy as well. But this study population was DMARD naive.
“Also, the literature usually describes a better outcome in men for anti-TNF, which was not seen here,” she added.
“As the effect of tocilizumab seems to be greater in men not only in remission rates, but also in infection rates, I do believe an effect on the IL-6 signaling and immunological sequelae to be the underlying factor,” Dr. Fritsch-Stork said. “However, I agree with the authors that unknown, noninflammatory, sex-dependent effects on pain sensation might play a role.”
Even though the applicability of the study isn’t clear, she said, “it is important information for future investigations.”
Ms. Lend and Dr. Fritsch-Stork reported no relevant financial disclosures. Dr. Sepriano reported financial relationships with UCB, Novartis, and Lilly. Dr. Nikiphorou reported financial relationships with Pfizer, Gilead, Galapagos, Lilly, and Fresenius.

Hip fractures likely to double by 2050 as population ages
The annual incidence of hip fractures declined in most countries from 2005 to 2018, but this rate is projected to roughly double by 2050, according to a new study of 19 countries/regions.
The study by Chor-Wing Sing, PhD, and colleagues was presented at the annual meeting of the American Society of Bone and Mineral Research. The predicted increase in hip fractures is being driven by the aging population, with the population of those age 85 and older projected to increase 4.5-fold from 2010 to 2050, they note.
The researchers also estimate that from 2018 to 2050 the incidence of fractures will increase by 1.9-fold overall – more in men (2.4-fold) than in women (1.7-fold).
In addition, rates of use of osteoporosis drugs 1 year after a hip fracture were less than 50%, with less treatment in men. Men were also more likely than women to die within 1 year of a hip fracture.
The researchers conclude that “larger and more collaborative efforts among health care providers, policymakers, and patients are needed to prevent hip fractures and improve the treatment gap and post-fracture care, especially in men and the oldest old.”
Aging will fuel rise in hip fractures; more preventive treatment needed
“Even though there is a decreasing trend of hip fracture incidence in some countries, such a percentage decrease is insufficient to offset the percentage increase in the aging population,” senior co-author Ching-Lung Cheung, PhD, associate professor in the department of pharmacology and pharmacy at the University of Hong Kong, explained to this news organization.
The takeaways from the study are that “a greater effort on fracture prevention should be made to avoid the continuous increase in the number of hip fractures,” he said.
In addition, “although initiation of anti-osteoporosis medication after hip fracture is recommended in international guidelines, the 1-year treatment rate [was] well below 50% in most of the countries and regions studied. This indicates the treatment rate is far from optimal.”
“Our study also showed that the use of anti-osteoporosis medications following a hip fracture is lower in men than in women by 30% to 67%,” he said. “Thus, more attention should be paid to preventing and treating hip fractures in men.”
“The greater increase in the projected number of hip fractures in men than in women “could be [because] osteoporosis is commonly perceived as a ‘woman’s disease,’ ” he speculated.
Invited to comment, Juliet Compston, MD, who selected the study as one of the top clinical science highlight abstracts at the ASBMR meeting, agrees that “there is substantial room for improvement” in osteoporosis treatment rates following a hip fracture “in all the regions covered by the study.”
“In addition,” she continues, “the wide variations in treatment rates can provide important lessons about the most effective models of care for people who sustain a hip fracture: for example, fracture liaison services.”
Men suffer as osteoporosis perceived to be a ‘woman’s disease’
The even lower treatment rate in men than women is “concerning and likely reflects the mistaken perception that osteoporosis is predominantly a disease affecting women,” notes Dr. Compston, emeritus professor of bone medicine, University of Cambridge, United Kingdom.
Also invited to comment, Peter R. Ebeling, MD, outgoing president of the ASBMR, said that the projected doubling of hip fractures “is likely mainly due to aging of the population, with increasing lifespan for males in particular. However, increasing urbanization and decreasing weight-bearing exercise as a result are likely to also contribute in developing countries.”
“Unfortunately, despite the advances in treatments for osteoporosis over the last 25 years, osteoporosis treatment rates remain low, and osteoporosis remains undiagnosed in postmenopausal women and older men,” added Dr. Ebeling, from Monash University, Melbourne, who was not involved with the research.
“More targeted screening for osteoporosis would help,” he said, “as would treating patients for it following other minimal trauma fractures (vertebral, distal radius, and humerus, etc.), since if left untreated, about 50% of these patients will have hip fractures later in life.”
“Some countries may be doing better because they have health quality standards for hip fracture (for example, surgery within 24 hours, investigation, and treatment for osteoporosis). In other countries like Australia, bone density tests and treatment for osteoporosis are reimbursed, increasing their uptake.”
The public health implications of this study are “substantial” according to Dr. Compston. “People who have sustained a hip fracture are at high risk of subsequent fractures if untreated. There is a range of safe, cost-effective pharmacological therapies to reduce fracture rate, and wider use of these would have a major impact on the current and future burden imposed by hip fractures in the elderly population.”
Similarly, Dr. Ebeling noted that “prevention is important to save a huge health burden for patients and costs for society.”
“Patients with minimal trauma fractures (particularly hip or spinal fractures) should be investigated and treated for osteoporosis with care pathways established in the hospitals, reaching out to the community [fracture liaison services],” he said.
Support for these is being sought under Medicare in the United States, he noted, and bone densitometry reimbursement rates also need to be higher in the United States.
Projections for number of hip fractures to 2050
Previous international reviews of hip fractures have been based on heterogeneous data from more than 10 to 30 years ago, the researchers note.
They performed a retrospective cohort study using a common protocol across 19 countries/regions, as described in an article about the protocol published in BMJ Open.
They analyzed data from adults aged 50 and older who were hospitalized with a hip fracture to determine 1) the annual incidence of hip fractures in 2008-2015; 2) the uptake of drugs to treat osteoporosis at 1 year after a hip fracture; and 3) all-cause mortality at 1 year after a hip fracture.
In a second step, they estimated the number of hip fractures that would occur from 2030 to 2050, using World Bank population growth projections.
The data are from 20 health care databases from 19 countries/regions: Oceania (Australia, New Zealand), Asia (Hong Kong, Japan, Singapore, South Korea, Taiwan, and Thailand), Northern Europe (Denmark, Finland, and U.K.), Western Europe (France, Germany, Italy, The Netherlands, and Spain), and North and South America (Canada, United States, and Brazil).
The population in Japan was under age 75. U.S. data are from two databases: Medicare (age ≥ 65) and Optum.
Most databases (13) covered 90%-100% of the national population, and the rest covered 5%-70% of the population.
From 2008 to 2015, the annual incidence of hip fractures declined in 11 countries/regions (Singapore, Denmark, Hong Kong, Taiwan, Finland, U.K., Italy, Spain, United States [Medicare], Canada, and New Zealand).
“One potential reason that some countries have seen relatively large declines in hip fractures is better osteoporosis management and post-fracture care,” said Dr. Sing in a press release issued by ASBMR. “Better fall-prevention programs and clearer guidelines for clinical care have likely made a difference.”
Hip fracture incidence increased in five countries (The Netherlands, South Korea, France, Germany, and Brazil) and was stable in four countries (Australia, Japan, Thailand, and United States [Optum]).
The United Kingdom had the highest rate of osteoporosis treatment at 1-year after a hip fracture (50.3%). Rates in the other countries/regions ranged from 11.5% to 37%.
Fewer men than women were receiving drugs for osteoporosis at 1 year (range 5.1% to 38.2% versus 15.0% to 54.7%).
From 2005 to 2018, rates of osteoporosis treatment at 1 year after a hip fracture declined in six countries, increased in four countries, and were stable in five countries.
All-cause mortality within 1 year of hip fracture was higher in men than in women (range 19.2% to 35.8% versus 12.1% to 25.4%).
“Among the studied countries and regions, the U.S. ranks fifth with the highest hip fracture incidence,” Dr. Cheung replied when specifically asked about this. “The risk of hip fracture is determined by multiple factors: for example, lifestyle, diet, genetics, as well as management of osteoporosis,” he noted.
“Denmark is the only country showing no projected increase, and it is because Denmark had a continuous and remarkable decrease in the incidence of hip fractures,” he added, which “can offset the number of hip fractures contributed by the population aging.”
The study was funded by Amgen. Dr. Sing and Dr. Cheung have reported no relevant financial relationships. One of the study authors is employed by Amgen.

“Unfortunately, despite the advances in treatments for osteoporosis over the last 25 years, osteoporosis treatment rates remain low, and osteoporosis remains undiagnosed in postmenopausal women and older men,” added Dr. Ebeling, from Monash University, Melbourne, who was not involved with the research.
“More targeted screening for osteoporosis would help,” he said, “as would treating patients for it following other minimal trauma fractures (vertebral, distal radius, and humerus, etc.), since if left untreated, about 50% of these patients will have hip fractures later in life.”
“Some countries may be doing better because they have health quality standards for hip fracture (for example, surgery within 24 hours, investigation, and treatment for osteoporosis). In other countries like Australia, bone density tests and treatment for osteoporosis are reimbursed, increasing their uptake.”
The public health implications of this study are “substantial” according to Dr. Compston. “People who have sustained a hip fracture are at high risk of subsequent fractures if untreated. There is a range of safe, cost-effective pharmacological therapies to reduce fracture rate, and wider use of these would have a major impact on the current and future burden imposed by hip fractures in the elderly population.”
Similarly, Dr. Ebeling noted that “prevention is important to save a huge health burden for patients and costs for society.”
“Patients with minimal trauma fractures (particularly hip or spinal fractures) should be investigated and treated for osteoporosis with care pathways established in the hospitals, reaching out to the community [fracture liaison services],” he said.
Support for these is being sought under Medicare in the United States, he noted, and bone densitometry reimbursement rates also need to be higher in the United States.
Projections for number of hip fractures to 2050
Previous international reviews of hip fractures have been based on heterogeneous data from more than 10 to 30 years ago, the researchers note.
They performed a retrospective cohort study using a common protocol across 19 countries/regions, as described in an article about the protocol published in BMJ Open.
They analyzed data from adults aged 50 and older who were hospitalized with a hip fracture to determine 1) the annual incidence of hip fractures in 2008-2015; 2) the uptake of drugs to treat osteoporosis at 1 year after a hip fracture; and 3) all-cause mortality at 1 year after a hip fracture.
In a second step, they estimated the number of hip fractures that would occur from 2030 to 2050, using World Bank population growth projections.
The data are from 20 health care databases from 19 countries/regions: Oceania (Australia, New Zealand), Asia (Hong Kong, Japan, Singapore, South Korea, Taiwan, and Thailand), Northern Europe (Denmark, Finland, and U.K.), Western Europe (France, Germany, Italy, The Netherlands, and Spain), and North and South America (Canada, United States, and Brazil).
The population in Japan was under age 75. U.S. data are from two databases: Medicare (age ≥ 65) and Optum.
Most databases (13) covered 90%-100% of the national population, and the rest covered 5%-70% of the population.
From 2008 to 2015, the annual incidence of hip fractures declined in 11 countries/regions (Singapore, Denmark, Hong Kong, Taiwan, Finland, U.K., Italy, Spain, United States [Medicare], Canada, and New Zealand).
“One potential reason that some countries have seen relatively large declines in hip fractures is better osteoporosis management and post-fracture care,” said Dr. Sing in a press release issued by ASBMR. “Better fall-prevention programs and clearer guidelines for clinical care have likely made a difference.”
Hip fracture incidence increased in five countries (The Netherlands, South Korea, France, Germany, and Brazil) and was stable in four countries (Australia, Japan, Thailand, and United States [Optum]).
The United Kingdom had the highest rate of osteoporosis treatment at 1-year after a hip fracture (50.3%). Rates in the other countries/regions ranged from 11.5% to 37%.
Fewer men than women were receiving drugs for osteoporosis at 1 year (range 5.1% to 38.2% versus 15.0% to 54.7%).
From 2005 to 2018, rates of osteoporosis treatment at 1 year after a hip fracture declined in six countries, increased in four countries, and were stable in five countries.
All-cause mortality within 1 year of hip fracture was higher in men than in women (range 19.2% to 35.8% versus 12.1% to 25.4%).
“Among the studied countries and regions, the U.S. ranks fifth with the highest hip fracture incidence,” Dr. Cheung replied when specifically asked about this. “The risk of hip fracture is determined by multiple factors: for example, lifestyle, diet, genetics, as well as management of osteoporosis,” he noted.
“Denmark is the only country showing no projected increase, and it is because Denmark had a continuous and remarkable decrease in the incidence of hip fractures,” he added, which “can offset the number of hip fractures contributed by the population aging.”
The study was funded by Amgen. Dr. Sing and Dr. Cheung have reported no relevant financial relationships. One of the study authors is employed by Amgen.

The annual incidence of hip fractures declined in most countries from 2005 to 2018, but this rate is projected to roughly double by 2050, according to a new study of 19 countries/regions.
The study by Chor-Wing Sing, PhD, and colleagues was presented at the annual meeting of the American Society of Bone and Mineral Research. The predicted increase in hip fractures is being driven by the aging population, with the population of those age 85 and older projected to increase 4.5-fold from 2010 to 2050, they note.
The researchers also estimate that from 2018 to 2050 the incidence of fractures will increase by 1.9-fold overall – more in men (2.4-fold) than in women (1.7-fold).
In addition, rates of use of osteoporosis drugs 1 year after a hip fracture were less than 50%, with less treatment in men. Men were also more likely than women to die within 1 year of a hip fracture.
The researchers conclude that “larger and more collaborative efforts among health care providers, policymakers, and patients are needed to prevent hip fractures and improve the treatment gap and post-fracture care, especially in men and the oldest old.”
Aging will fuel rise in hip fractures; more preventive treatment needed
“Even though there is a decreasing trend of hip fracture incidence in some countries, such a percentage decrease is insufficient to offset the percentage increase in the aging population,” senior co-author Ching-Lung Cheung, PhD, associate professor in the department of pharmacology and pharmacy at the University of Hong Kong, explained to this news organization.
The takeaways from the study are that “a greater effort on fracture prevention should be made to avoid the continuous increase in the number of hip fractures,” he said.
In addition, “although initiation of anti-osteoporosis medication after hip fracture is recommended in international guidelines, the 1-year treatment rate [was] well below 50% in most of the countries and regions studied. This indicates the treatment rate is far from optimal.”
“Our study also showed that the use of anti-osteoporosis medications following a hip fracture is lower in men than in women by 30% to 67%,” he said. “Thus, more attention should be paid to preventing and treating hip fractures in men.”
“The greater increase in the projected number of hip fractures in men than in women “could be [because] osteoporosis is commonly perceived as a ‘woman’s disease,’ ” he speculated.
Invited to comment, Juliet Compston, MD, who selected the study as one of the top clinical science highlight abstracts at the ASBMR meeting, agrees that “there is substantial room for improvement” in osteoporosis treatment rates following a hip fracture “in all the regions covered by the study.”
“In addition,” she continues, “the wide variations in treatment rates can provide important lessons about the most effective models of care for people who sustain a hip fracture: for example, fracture liaison services.”
Men suffer as osteoporosis perceived to be a ‘woman’s disease’
The even lower treatment rate in men than women is “concerning and likely reflects the mistaken perception that osteoporosis is predominantly a disease affecting women,” notes Dr. Compston, emeritus professor of bone medicine, University of Cambridge, United Kingdom.
Also invited to comment, Peter R. Ebeling, MD, outgoing president of the ASBMR, said that the projected doubling of hip fractures “is likely mainly due to aging of the population, with increasing lifespan for males in particular.

Crystal bone algorithm predicts early fractures, uses ICD codes
The Crystal Bone (Amgen) novel algorithm predicted 2-year risk of osteoporotic fractures in a large dataset with an accuracy that was consistent with FRAX 10-year risk predictions, researchers report.
The algorithm was built using machine learning and artificial intelligence to predict fracture risk based on International Classification of Diseases (ICD) codes, as described in an article published in the Journal of Medical Internet Research.
The current validation study was presented September 9 as a poster at the annual meeting of the American Society for Bone and Mineral Research.
The scientists validated the algorithm in more than 100,000 patients aged 50 and older (that is, at risk of fracture) who were part of the Reliant Medical Group dataset (a subset of Optum Care).
Importantly, the algorithm predicted increased fracture in many patients who did not have a diagnosis of osteoporosis.
The next steps are validation in other datasets to support the generalizability of Crystal Bone across U.S. health care systems, Elinor Mody, MD, Reliant Medical Group, and colleagues report.
“Implementation research, in which patients identified by Crystal Bone undergo a bone health assessment and receive ongoing management, will help inform the clinical utility of this novel algorithm,” they conclude.
At the poster session, Tina Kelley, Optum Life Sciences, explained: “It’s a screening tool that says: ‘These are your patients that maybe you should spend a little extra time with, ask a few extra questions.’ ”
However, further study is needed before it should be used in clinical practice, she emphasized to this news organization.
‘A very useful advance’ but needs further validation
Invited to comment, Peter R. Ebeling, MD, outgoing president of the ASBMR, noted that “many clinicians now use FRAX to calculate absolute fracture risk and select patients who should initiate anti-osteoporosis drugs.”
With FRAX, clinicians input a patient’s age, sex, weight, height, previous fracture, [history of] parent with fractured hip, current smoking status, glucocorticoids, rheumatoid arthritis, secondary osteoporosis, alcohol (3 units/day or more), and bone mineral density (by DXA at the femoral neck) into the tool, to obtain a 10-year probability of fracture.
“Crystal Bone takes a different approach,” Dr. Ebeling, from Monash University, Melbourne, who was not involved with the research but who disclosed receiving funding from Amgen, told this news organization in an email.
The algorithm uses electronic health records (EHRs) to identify patients who are likely to have a fracture within the next 2 years, he explained, based on diagnoses and medications associated with osteoporosis and fractures. These include ICD-10 codes for fractures at various sites and secondary causes of osteoporosis (such as rheumatoid and other inflammatory arthritis, chronic obstructive pulmonary disease, asthma, celiac disease, and inflammatory bowel disease).
“This is a very useful advance,” Dr. Ebeling summarized, “in that it would alert the clinician to patients in their practice who have a high fracture risk and need to be investigated for osteoporosis and initiated on treatment. Otherwise, the patients would be missed, as currently often occurs.”
“It would need to be adaptable to other [EMR] systems and to be validated in a large separate population to be ready to enter clinical practice,” he said, “but these data look very promising with a good [positive predictive value (PPV)].”
Similarly, Juliet Compston, MD, said: “It provides a novel, fully automated approach to population-based screening for osteoporosis using EHRs to identify people at high imminent risk of fracture.”
Dr. Compston, emeritus professor of bone medicine, University of Cambridge, England, who was not involved with the research but who also disclosed being a consultant for Amgen, selected the study as one of the top clinical science highlights abstracts at the meeting.
“The algorithm looks at ICD codes for previous history of fracture, medications that have adverse effects on bone – for example glucocorticoids, aromatase inhibitors, and anti-androgens – as well as chronic diseases that increase the risk of fracture,” she explained.
“FRAX is the most commonly used tool to estimate fracture probability in clinical practice and to guide treatment decisions,” she noted. However, “currently it requires human input of data into the FRAX website and is generally only performed on individuals who are selected on the basis of clinical risk factors.”
“The Crystal Bone algorithm offers the potential for fully automated population-based screening in older adults to identify those at high risk of fracture, for whom effective therapies are available to reduce fracture risk,” she summarized.
“It needs further validation,” she noted, “and implementation into clinical practice requires the availability of high-quality EHRs.”
Algorithm validated in 106,328 patients aged 50 and older
Despite guidelines that recommend screening for osteoporosis in women aged 65 and older, men older than 70, and adults aged 50-79 with risk factors, real-world data suggest such screening is low, the researchers note.
The current validation study identified 106,328 patients aged 50 and older who had at least 2 years of consecutive medical history with the Reliant Medical Group from December 2014 to November 2020 as well as at least two EHR codes.
The accuracy of predicting a fracture within 2 years, expressed as area under the receiver operating characteristic (AUROC), was 0.77, where 1 is perfect, 0.5 is no better than random selection, 0.7 to 0.8 is acceptable, and 0.8 to 0.9 indicates excellent predictive accuracy.
In the entire Optum Reliant population older than 50, the risk of fracture within 2 years was 1.95%.
The algorithm identified four groups with a greater risk: 19,100 patients had a threefold higher risk of fracture within 2 years, 9,246 patients had a fourfold higher risk, 3,533 patients had a sevenfold higher risk, and 1,735 patients had a ninefold higher risk.
Many of these patients had no prior diagnosis of osteoporosis
For example, in the 19,100 patients with a threefold greater risk of fracture in 2 years, 69% of patients had not been diagnosed with osteoporosis (49% of them had no history of fracture and 20% did have a history of fracture).
The algorithm had a positive predictive value of 6%-18%, a negative predictive value of 98%-99%, a specificity of 81%-98%, and a sensitivity of 18%-59%, for the four groups.
The study was funded by Amgen. Dr. Mody and another author are Reliant Medical Group employees. Ms. Kelley and another author are Optum Life Sciences employees. One author is an employee at Landing AI. Two authors are Amgen employees and own Amgen stock. Dr. Ebeling has disclosed receiving research funding from Amgen, Sanofi, and Alexion, and his institution has received honoraria from Amgen and Kyowa Kirin.
