A small cohort study of pediatric rheumatology patients with generalized joint hypermobility (GJH) who presented to a specialized rheumatology* clinic suggests that many such patients have abnormal bleeding symptoms, in comparison with health control patients.

The study of 81 patients with GJH found that about three quarters had significantly elevated median bleeding scores, but only 12% had been assessed by hematology for bleeding.

Dr. Nicole E. Kendel

“We propose that screening for bleeding symptoms should be integrated into the routine care for all patients with GJH, with hematology referrals for patients with increased bleeding concerns,” wrote a research team led by Nicole E. Kendel, MD, a pediatric hematologist-oncologist at Akron Children’s Hospital in Ohio, in a study published online in Arthritis Care and Research.

“Further studies are needed to understand the mechanism of bleeding, evaluate comorbidities associated with these bleeding symptoms, and potentially allow for tailored pharmacologic therapy,” the authors stated.
 

Background

Dr. Kendel’s team had reported moderate menstruation-associated limitations in school, social, and physical activities among female adolescents with GJH. “This cohort also experienced nonreproductive bleeding symptoms and demonstrated minimal hemostatic laboratory abnormalities, indicating that this population may be underdiagnosed and subsequently poorly managed,” she said in an interview. “As excessive bleeding symptoms could have a significant impact on overall health and quality of life, we thought it was important to define the incidence and natural course of bleeding symptoms in a more generalized subset of this population.”

Although the investigators hypothesized that there would be a statistically significant increase in bleeding scores, “we were still impressed by the frequency of abnormal scores, particularly when looking at the low percentage of patients [12%] who had previously been referred to hematology,” she said.
 

Study results

The median age of the study cohort was 13 years (interquartile range, 10-16 years), and 72.8% were female. The mean Beighton score, which measures joint flexibility, was 6.2 (range, 4-9). All participants were seen by rheumatologists and were diagnosed for conditions on the hypermobility spectrum. Those conditions ranged from GJH to hypermobile Ehlers-Danlos syndrome (hEDS).

Abnormal bleeding, as measured by the International Society on Thrombosis and Haemostasis Bleeding Assessment Tool, was found in 75% (95% confidence interval [CI], 64%-84%). Overall mean and median bleeding scores were 5.2 and 4, respectively; scores ranged from 0 to 16. Abnormal scores of ≥ 3 were observed for patients < 8 years of age, ≥ 4 for men ≥ 18 years of age, and ≥ 6 for women ≥ 18 years of age. These measures were significantly elevated compared with those reported for historical healthy pediatric control persons (P < .001).

The most common hemorrhagic symptom was oral bleeding (74.1%) that occurred with tooth brushing, flossing, tooth loss, or eruption. Others reported easy bruising (59.3%) and bleeding from minor wounds (42%). In terms of procedures, tooth extraction requiring additional packing was reported by 25.9%, and 22.2% reported significant bleeding after otolaryngologic procedures, such as tonsillectomy/adenoidectomy, septoplasty, and nasal turbinate reduction.

Prolonged or heavy menstrual periods were reported by 37.3% of female patients.

Bleeding scores did not differ by biological sex or NSAID use, nor did any correlation emerge between patients’ bleeding and Beighton scores. However, there was a positive correlation with increasing age, a phenomenon observed with other bleeding disorders and in the healthy population, the authors noted.

Of the 10 study participants who had previously undergone hematologic assessment, one had been diagnosed with acquired, heart disease–related von Willebrand disease, and another with mild bleeding disorder.

Severe connective tissue disorders are associated with increased bleeding symptoms in the adult population, Dr. Kendel said, but few studies have assessed bleeding across the GJH spectrum, particularly in children.

Bleeding is thought to be due to modifications of collagen in the blood vessels. “These modifications create mechanical weakness of the vessel wall, as well as defective subendothelial connective tissue supporting those blood vessels,” Dr. Kendel explained. She noted that altered collagen creates defective interactions between collagen and other coagulation factors.

“Even in the presence of a normal laboratory evaluation, GJH can lead to symptoms consistent with a mild bleeding disorder,” she continued. “These symptoms are both preventable and treatable. I’m hopeful more centers will start routinely evaluating for increased bleeding symptoms, with referral to hematology for those with increased bleeding concerns.”

Commenting on the study’s recommendation, Beth S. Gottlieb, MD, chief of the division of pediatric rheumatology at Northwell Health in New Hyde Park, N.Y., who was not involved in the investigation, said a brief questionnaire on bleeding risk is a reasonable addition to a rheumatology office visit.

Dr. Beth S. Gottlieb

“Joint hypermobility is very common, but not all affected children meet the criteria for the hypermobile form of hEDS,” she told this news organization. “Screening for bleeding tendency is often done as routine medical history questions. Once a child is identified as hypermobile, these screening questions are usually asked, but utilizing one of the formal bleeding risk questionnaires is not currently routine.”

According to Dr. Gottlieb, it remains unclear whether screening would have a significant impact on children who have been diagnosed with hypermobility. “Most of these children are young and may not yet have a significant history for bleeding tendency,” she said. “Education of families is always important, and it will be essential to educate without adding unnecessary stress. Screening guidelines may be an important tool that is easy to incorporate into routine clinical practice.”
 

 

 

Limitation

The study was limited by selection bias, as patients had all been referred to a specialized rheumatology clinic.

The study was supported by the Clinical and Translational Intramural Funding Program of the Abigail Wexner Research Institute. The authors and Dr. Gottlieb have disclosed no relevant financial relationships.

Corticosteroid injections may worsen knee OA progression

Article Type

Tue, 12/20/2022 - 12:20

Corticosteroid (CS) injections may worsen progression of knee osteoarthritis as seen on radiography and whole-knee MRI. Injecting hyaluronic acid (HA) instead, or managing the condition without injections, may better preserve knee structure and cartilage, according to results of two related studies presented at the annual meeting of the Radiological Society of North America.

The findings come nonrandomized, observational cohort studies, leading knee OA experts to call for further study in randomized trial settings. In the meantime, shared decision-making between patients and clinicians is advised on the use of these injections.

For knee OA, most patients seek a noninvasive treatment for symptomatic relief. “At least 10% of these patients undergo local treatment with injectable corticosteroids or hyaluronic acid,” the lead author of one of the studies, Upasana Upadhyay Bharadwaj, MD, research fellow in musculoskeletal radiology at the University of California, San Francisco, said in a video press release.

Researchers in both studies used data and images from the Osteoarthritis Initiative (OAI), a multicenter, longitudinal, observational study of 4,796 U.S. patients aged 45-79 years with knee OA. Participants were enrolled from February 2004 to May 2006.

The OAI maintains a natural history database of information regarding participants’ clinical evaluation data, x-rays, MRI scans, and a biospecimen repository. Data are available to researchers worldwide.
 

Two studies draw similar conclusions

In one study, Dr. Bharadwaj and colleagues found that HA injections appeared to show decreased knee OA progression in bone marrow lesions.

They investigated 8 patients who received one CS injection, 12 who received one HA injection, and 40 control persons who received neither treatment. Participants were propensity-score matched by age, sex, body mass index (BMI), Kellgren-Lawrence (KL) grade, Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), and Physical Activity Scale for the Elderly (PASE).

The researchers semiquantitatively graded three Tesla MRI scans that had been obtained at baseline, 2 years before the injection, and 2 years after the injection, using whole-organ MRI score (WORMS) for the meniscus, bone marrow lesions, cartilage, joint effusion, and ligaments.

They quantified OA progression using the difference in WORMS between baseline and 2-year follow-up, and they used linear regression models, adjusted for age, sex, BMI, KL grade, WOMAC, and PASE, to identify the link between type of injection and progression of WORMS.

At 2 years, the authors found a significant association between CS injection and postinjection progression of WORMS over 2 years for the knee overall, the lateral meniscus, lateral cartilage, and medial cartilage. There was no significant link between HA injection and postinjection progression of WORMS or between either injection type and progression of pain, as quantified by WOMAC. There was also no significant difference in progression of WORMS over the 2 years prior to injection for CS and HA injections.

“Corticosteroid injections must be administered with caution with respect to long-term effects on osteoarthritis,” Dr. Bharadwaj advised. “Hyaluronic acid injections, on the other hand, may slow down progression of knee osteoarthritis and alleviate long-term effects while offering similar symptomatic relief to corticosteroid injections. Overall, they are perhaps a safer alternative when looking at medium- and long-term disease course of knee osteoarthritis.”

In the second study, lead author Azad Darbandi, MS, a fourth-year medical student at Chicago Medical School, North Chicago, and colleagues found that patients who received CS injections experienced significantly more medial joint space narrowing.

They identified 210 knees with imaging at baseline and at 48 months that received CS injections, and 59 that received HA injections; 6,827 knees served as controls. The investigators matched 50 patients per group on the basis of confounding factors, which included age, sex, BMI, comorbidities, surgery, and semiquantitative imaging outcomes at baseline. They performed ANCOVA testing using 48-month semiquantitative imaging outcomes as dependent variables and confounding variables as covariates.

The researchers analyzed joint space narrowing, KL grade, and tibia/femur medial/lateral compartment osteophyte formation and sclerosis.

At 4 years, the average KL grade in the CS group was 2.79, it was 2.11 in the HA group,;and it was 2.37 in the control group. Intergroup comparisons showed significant differences in KL grade between CS and HA groups and between CS and control groups. Medial compartment joint space narrowing was 1.56 in the CS group, 1.11 in the HA group, and 1.18 in controls. There was a significant difference between the CS and control groups. Other dependent variables were not significant.

“These preliminary results suggest that corticosteroid injections accelerated the radiographic progression of osteoarthritis, specifically medial joint space narrowing and Kellgren-Lawrence grading, whereas hyaluronic acid injections did not,” Mr. Darbandi said in an interview.

“OA radiographic progression does not always correlate with clinical progression, and further research is needed,” he added.

Proper matching of patients at baseline for confounding factors is a strength of the study, Mr. Darbandi said, while the retrospective study design is a weakness.
 

 

 

Experts share their perspectives on the preliminary results

Michael M. Kheir, MD, assistant professor of orthopedic surgery at the University of Michigan Health System, who was not involved in the studies, said he would like to see further related research.

“Perhaps steroid injections are not as benign as they once seemed,” he added. “They should be reserved for patients who already have significant arthritis and are seeking temporary relief prior to surgical reconstruction with a joint replacement, or for patients with recalcitrant pain after having already tried HA injections.”

William A. Jiranek, MD, professor and orthopedic surgeon at Duke Health in Morrisville, N.C., who also was not involved in the studies, was not surprised by the findings.

“It is important to do these studies to learn that steroid injections do not come with zero cost,” he said.

“I am pretty sure that a percentage of these patients had no cartilage loss at all,” he added. “We need to understand which OA phenotypes are not at risk of progressive cartilage loss from steroid injections.”

Annunziato (Ned) Amendola, MD, professor and sports medicine orthopedic surgeon at Duke Health in Durham, N.C., who was also not involved in the studies, said he would like to know how injection effectiveness and activity level are related.

“If the injections were effective at relieving pain, and the patients were more active, that may have predisposed to more joint wear,” he said. “It’s like tires that last longer if you don’t abuse them.”
 

Shared decision-making and further research recommended

Amanda E. Nelson, MD, associate professor of medicine in the division of rheumatology, allergy, and immunology at the University of North Carolina at Chapel Hill, said: “The lack of randomization introduces potential biases around why certain therapies (CS injection, HA injection, or neither) were selected over others (such as disease severity, preference, comorbid conditions, other contraindications, etc), thus making interpretation of the findings challenging.

“The causal relationship remains in question, and questions around the efficacy of intra-articular HA in particular, and the ideal settings for intra-articular therapy in general, persist,” noted Dr. Nelson, who was also not involved in the studies. “Thus, shared decision-making between patients and their providers is essential when considering these options.”

C. Kent Kwoh, MD, professor of medicine and medical imaging at the University of Arizona and director of the University of Arizona Arthritis Center, both in Tucson, said in an interview that these types of studies are important because CS injections are common treatments for knee OA, they are recommended in treatment guidelines, and other good options are lacking.

But he pointed out that the results of these two studies need to be interpreted with caution and should not be used to decide the course of treatment.

“These data are hypothesis generating. They suggest association, but they do not show causation,” said Dr. Kwoh, who was also not involved in the studies. “Both studies are secondary analyses of data collected from the OAI, which was not specifically designed to answer the questions these studies are posing.

“The OAI was not a treatment study, and participants were seen only once a year or so. They may have had joint injections anytime from only days to around 1 year before their visit, and their levels of activity or pain just prior to or just after their joint injections were not reported,” Dr. Kwoh explained.

The reasons why patients did or did not receive a specific joint injection – including their socioeconomic status, race, access to insurance, and other confounding factors – were not assessed and may have affected the results, he added.

The fact that both studies used the same data and came to the same conclusions gives the conclusions some strength, he said, but “the gold standard to understanding causation would be a randomized, controlled trial.”

Mr. Darbandi’s research received grant support from Boeing, His c-authors, as well as all experts not involved in the studies, reported no relevant financial relationshiips. Dr. Bharadwaj did not provide conflict-of-interest and funding details. Dr. Kwoh reported membership on panels that have developed guidelines for the management of knee OA.

Nelson, MD, associate professor of medicine in the division of rheumatology, allergy, and immunology at the University of North Carolina at Chapel Hill, said: “The lack of randomization introduces potential biases around why certain therapies (CS injection, HA injection, or neither) were selected over others (such as disease severity, preference, comorbid conditions, other contraindications, etc), thus making interpretation of the findings challenging.

“The causal relationship remains in question, and questions around the efficacy of intra-articular HA in particular, and the ideal settings for intra-articular therapy in general, persist,” noted Dr. Nelson, who was also not involved in the studies. “Thus, shared decision-making between patients and their providers is essential when considering these options.”

C. Kent Kwoh, MD, professor of medicine and medical imaging at the University of Arizona and director of the University of Arizona Arthritis Center, both in Tucson, said in an interview that these types of studies are important because CS injections are common treatments for knee OA, they are recommended in treatment guidelines, and other good options are lacking.

But he pointed out that the results of these two studies need to be interpreted with caution and should not be used to decide the course of treatment.

“These data are hypothesis generating. They suggest association, but they do not show causation,” said Dr. Kwoh, who was also not involved in the studies. “Both studies are secondary analyses of data collected from the OAI, which was not specifically designed to answer the questions these studies are posing.

“The OAI was not a treatment study, and participants were seen only once a year or so. They may have had joint injections anytime from only days to around 1 year before their visit, and their levels of activity or pain just prior to or just after their joint injections were not reported,” Dr. Kwoh explained.

The reasons why patients did or did not receive a specific joint injection – including their socioeconomic status, race, access to insurance, and other confounding factors – were not assessed and may have affected the results, he added.

The fact that both studies used the same data and came to the same conclusions gives the conclusions some strength, he said, but “the gold standard to understanding causation would be a randomized, controlled trial.”

Mr. Darbandi’s research received grant support from Boeing, His c-authors, as well as all experts not involved in the studies, reported no relevant financial relationshiips. Dr. Bharadwaj did not provide conflict-of-interest and funding details. Dr. Kwoh reported membership on panels that have developed guidelines for the management of knee OA.

Corticosteroid (CS) injections may worsen progression of knee osteoarthritis as seen on radiography and whole-knee MRI. Injecting hyaluronic acid (HA) instead, or managing the condition without injections, may better preserve knee structure and cartilage, according to results of two related studies presented at the annual meeting of the Radiological Society of North America.

The findings come nonrandomized, observational cohort studies, leading knee OA experts to call for further study in randomized trial settings. In the meantime, shared decision-making between patients and clinicians is advised on the use of these injections.

For knee OA, most patients seek a noninvasive treatment for symptomatic relief. “At least 10% of these patients undergo local treatment with injectable corticosteroids or hyaluronic acid,” the lead author of one of the studies, Upasana Upadhyay Bharadwaj, MD, research fellow in musculoskeletal radiology at the University of California, San Francisco, said in a video press release.

Researchers in both studies used data and images from the Osteoarthritis Initiative (OAI), a multicenter, longitudinal, observational study of 4,796 U.S. patients aged 45-79 years with knee OA. Participants were enrolled from February 2004 to May 2006.

The OAI maintains a natural history database of information regarding participants’ clinical evaluation data, x-rays, MRI scans, and a biospecimen repository. Data are available to researchers worldwide.
 

Two studies draw similar conclusions

In one study, Dr. Bharadwaj and colleagues found that HA injections appeared to show decreased knee OA progression in bone marrow lesions.

They investigated 8 patients who received one CS injection, 12 who received one HA injection, and 40 control persons who received neither treatment. Participants were propensity-score matched by age, sex, body mass index (BMI), Kellgren-Lawrence (KL) grade, Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), and Physical Activity Scale for the Elderly (PASE).

The researchers semiquantitatively graded three Tesla MRI scans that had been obtained at baseline, 2 years before the injection, and 2 years after the injection, using whole-organ MRI score (WORMS) for the meniscus, bone marrow lesions, cartilage, joint effusion, and ligaments.

They quantified OA progression using the difference in WORMS between baseline and 2-year follow-up, and they used linear regression models, adjusted for age, sex, BMI, KL grade, WOMAC, and PASE, to identify the link between type of injection and progression of WORMS.

At 2 years, the authors found a significant association between CS injection and postinjection progression of WORMS over 2 years for the knee overall, the lateral meniscus, lateral cartilage, and medial cartilage. There was no significant link between HA injection and postinjection progression of WORMS or between either injection type and progression of pain, as quantified by WOMAC. There was also no significant difference in progression of WORMS over the 2 years prior to injection for CS and HA injections.

“Corticosteroid injections must be administered with caution with respect to long-term effects on osteoarthritis,” Dr. Bharadwaj advised. “Hyaluronic acid injections, on the other hand, may slow down progression of knee osteoarthritis and alleviate long-term effects while offering similar symptomatic relief to corticosteroid injections. Overall, they are perhaps a safer alternative when looking at medium- and long-term disease course of knee osteoarthritis.”

In the second study, lead author Azad Darbandi, MS, a fourth-year medical student at Chicago Medical School, North Chicago, and colleagues found that patients who received CS injections experienced significantly more medial joint space narrowing.

They identified 210 knees with imaging at baseline and at 48 months that received CS injections, and 59 that received HA injections; 6,827 knees served as controls. The investigators matched 50 patients per group on the basis of confounding factors, which included age, sex, BMI, comorbidities, surgery, and semiquantitative imaging outcomes at baseline. They performed ANCOVA testing using 48-month semiquantitative imaging outcomes as dependent variables and confounding variables as covariates.

The researchers analyzed joint space narrowing, KL grade, and tibia/femur medial/lateral compartment osteophyte formation and sclerosis.

At 4 years, the average KL grade in the CS group was 2.79, it was 2.11 in the HA group,;and it was 2.37 in the control group. Intergroup comparisons showed significant differences in KL grade between CS and HA groups and between CS and control groups. Medial compartment joint space narrowing was 1.56 in the CS group, 1.11 in the HA group, and 1.18 in controls. There was a significant difference between the CS and control groups. Other dependent variables were not significant.

“These preliminary results suggest that corticosteroid injections accelerated the radiographic progression of osteoarthritis, specifically medial joint space narrowing and Kellgren-Lawrence grading, whereas hyaluronic acid injections did not,” Mr. Darbandi said in an interview.

“OA radiographic progression does not always correlate with clinical progression, and further research is needed,” he added.

Proper matching of patients at baseline for confounding factors is a strength of the study, Mr. Darbandi said, while the retrospective study design is a weakness.
 

 

 

Experts share their perspectives on the preliminary results

Michael M. Kheir, MD, assistant professor of orthopedic surgery at the University of Michigan Health System, who was not involved in the studies, said he would like to see further related research.

“Perhaps steroid injections are not as benign as they once seemed,” he added. “They should be reserved for patients who already have significant arthritis and are seeking temporary relief prior to surgical reconstruction with a joint replacement, or for patients with recalcitrant pain after having already tried HA injections.”

William A. Jiranek, MD, professor and orthopedic surgeon at Duke Health in Morrisville, N.C., who also was not involved in the studies, was not surprised by the findings.

“It is important to do these studies to learn that steroid injections do not come with zero cost,” he said.

“I am pretty sure that a percentage of these patients had no cartilage loss at all,” he added. “We need to understand which OA phenotypes are not at risk of progressive cartilage loss from steroid injections.”

Annunziato (Ned) Amendola, MD, professor and sports medicine orthopedic surgeon at Duke Health in Durham, N.C., who was also not involved in the studies, said he would like to know how injection effectiveness and activity level are related.

“If the injections were effective at relieving pain, and the patients were more active, that may have predisposed to more joint wear,” he said. “It’s like tires that last longer if you don’t abuse them.”

Nelson, MD, associate professor of medicine in the division of rheumatology, allergy, and immunology at the University of North Carolina at Chapel Hill, said: “The lack of randomization introduces potential biases around why certain therapies (CS injection, HA injection, or neither) were selected over others (such as disease severity, preference, comorbid conditions, other contraindications, etc), thus making interpretation of the findings challenging.

Mind the geriatrician gap

These should be the best of times for geriatric medicine.

The baby boom has become a senior surge, bringing in a rapidly growing pool of aging patients for geriatricians to treat. According to the U.S. Census Bureau, more than 56 million adults aged 65 and older live in the United States. They account for about 17% of the nation’s population. That number is expected to hit 73 million by 2030 and 86 million by 2050.

The American Geriatrics Society estimates that 30% of older people require the attention of geriatricians. These clinicians excel in managing complex cases – patients with multiple comorbidities, such as coronary artery disease, dementia, and osteoporosis, who are taking a half dozen, and often more, medications.

But instead of thriving, geriatrics as a medical specialty appears to be hobbling. In the 2010s, geriatricians called for “25,000 [such specialists] by 2025.” As of 2021, 7123 certified geriatricians were practicing in the United States, according to the American Board of Medical Specialties.

The Health Resources and Services Administration, a federal agency that addresses medical workforce shortages, estimates that there will be 6,230 geriatricians by 2025, or approximately 1 for every 3,000 older adults requiring geriatric care. HRSA projects a shortage of 27,000 geriatricians by 2025.

The specialty has faced an uphill battle to attract fellows. This year, only 43% of the nation’s 177 geriatrics fellowship slots were filled, according to November’s National Resident Match Program report. Family medicine–based geriatrics achieved only a 32% fill rate, while internal medicine–based programs saw a rate of 45%.

“Our numbers are shrinking so we need another approach to make sure older adults get the care they need and deserve,” said G. Michael Harper, MD, president of the 6,000-member AGS.

But Dr. Harper, who practices at the University of California, San Francisco, and the San Francisco VA Medical Center, added a positive note: “We may be struggling to increase the number of board-certified geriatricians, but the field itself has made a lot of progress in terms of improving clinical care through advancements in science and in the ways we deliver care.”

Dr. Harper cited the Hospital Elder Life Program, a hospital model developed at the Harvard-affiliated Marcus Institute for Aging Research, which uses an interprofessional team and trained volunteers to prevent delirium and functional decline. HELP has been adopted by more than 200 hospitals worldwide and has been successful at returning older adults to their homes or previous living situations with maintained or improved ability to function, he said.

Mark Supiano, MD, professor and chief of geriatrics at the University of Utah, Salt Lake City, said the specialty has been in shortage mode since ABMS recognized it in 1988. He was in the initial cohort of fellowship-trained geriatricians, sitting for the first certifying exam in geriatrics offered that year.

“Back then, the demographic imperative of the aging of our society was on the horizon. We’re living it now. I knew enough to recognize it was coming and saw an opportunity,” Dr. Supiano said in an interview. “There was so much then that we didn’t know about how to understand aging or how to care for older adults that there really was such a knowledge gap.”

Dr. Supiano is an associate editor of Hazzard’s Geriatric Medicine and Gerontology (McGraw-Hill Education), which has more than doubled in pages and word count during his career.
 

 

 

Unfavorable finances

Katherine Thompson, MD, director of the geriatrics fellowship program at the University of Chicago and codirector of UChicago’s Successful Aging and Frailty Evaluation Clinic, said money is a major reason for the struggle. “I think probably the biggest driver is financial,” she said. “A lot of people are graduating medical school with really astronomical amounts of medical school loans.”

Geriatricians, like other doctors, carry a large debt – $200,000, on average, not counting undergraduate debt, according to the Association of American Medical Colleges.

But the typical geriatrician earns less than an internist or family medicine doctor who doesn’t undergo the additional year of training, Dr. Thompson said. “There’s not a lot of financial motivation to do this fellowship,” she said.

The jobs website Zippia reports that geriatricians earned roughly $165,000 per year on average in 2022. The average annual incomes in 2022 were $191,000 for pediatricians, $215,000 for family physicians, and $223,000 for internists, according to the site.

In other words, Dr. Harper said, “geriatrics is one of the few professions where you can actually do additional training and make less money.”

The reason for the pay issue is simple: Geriatricians treat patients covered by Medicare, whose reimbursement schedules lag behind those of commercial insurers. The Kaiser Family Foundation reported in 2020 that private insurance paid 143% of Medicare rates on average for physician services.

Dr. Harper said overall compensation for geriatricians has “not gained a lot of traction,” but they can earn comfortable livings.

Still, representation of the specialty on the American Medical Association’s Relative Value Scale Update Committee has led to approval by the Centers for Medicare & Medicaid Services of billing codes that pay geriatricians “for what they do. Examples include chronic care management, advance care planning, and dementia evaluation,” he said.

But the geriatrician gap goes beyond money.

Ageism, too, may play a role in residents not choosing geriatrics.

“Our culture is ageist. It definitely focuses on youth and looks at aging as being loss rather than just a change in what works well and what doesn’t work well,” said Mary Tinetti, MD, a geriatrician and researcher at Yale University, New Haven, Conn. “Ageism happens among physicians, just because they’re part of the broader society.”
 

Time for a new goal?

Dr. Tinetti said she’s optimistic that new ideas about geriatricians teaching other primary care clinicians about the tenets of geriatric medicine, which offer a wholistic approach to comorbidities, such as diabetes, atrial fibrillation, dementia, hypertension, hyperlipidemia, and polypharmacy problems faced by this population, especially those 85 and older.

She has called on her profession to abandon the goal of increasing the numbers of board-certified geriatricians – whom she refers to as big “G” geriatricians. She instead wants to develop a “small, elite workforce” that discovers and tests geriatrics principles through research, teaches these principles to all healthcare professions and to the public, and disseminates and implements the policies.

“We need a cadre of geriatricians who train all other clinicians in the care of older adults,” Dr. Tinetti said. “The goal is not more geriatricians but rather the preparation of all clinicians in the care of older adults.”

Dr. Thompson said geriatricians are teaching primary care specialists, nurses, social workers, and other health care providers the principles of age-friendly care. AGS has for the past 20 years led a program called the Geriatrics for Specialists Initiative to increase geriatrics knowledge and expertise of surgical and medical specialists.

Some specialties have taken the cue and have added geriatrics-related hyphens through additional training: geriatric-emergency, geriatric-general surgery, geriatric-hospitalists, and more.

HRSA runs programs to encourage physicians to train as geriatricians and geriatrics faculty, and it encourages the geriatrics interdisciplinary team approach.

Richard Olague, director of public affairs for HRSA, said his agency has invested over $160 million over the past 4 years in the education and training of geriatricians and other health care professionals who care for the elderly through its Geriatrics Workforce Enhancement Program and Geriatrics Academic Career Awards Program. In the academic year 2020-2021, the two programs trained 109 geriatricians; 456 other geriatric/gerontology providers and students; 44,450 other healthcare workforce professionals and students; and served 17,666 patients and 5,409 caregivers.

Dr. Harper, like his fellow geriatricians, tells young doctors that geriatrics is a fulfilling specialty.

“I get to care for the whole person and sometimes their families, too, and in the process form rich and meaningful relationships. And while I’m rarely in the position to cure, I always have the ability to care,” he said. “Sometimes that can mean being an advocate trying to make sure my patients receive the care they need, and other times it might mean protecting them from burdensome care that is unlikely to lead to any meaningful benefit. There is great reward in all of that.”

Dr. Supiano said geriatric patients are being helped by the Age-Friendly Health System initiative of the John A. Hartford Foundation and the Institute for Healthcare Improvement in partnership with the American Hospital Association and the Catholic Health Association of the United States. This is sort of a seal of approval for facilities committed to age-friendly care.

“When you go to your hospital, if they don’t have this age-friendly health system banner on the front door ... you either ask why that is not there, or you vote with your feet and go to another health system that is age friendly,” he said. “Geriatricians are eternal optimists.”

Katherine Thompson, MD, director of the geriatrics fellowship program at the University of Chicago and codirector of UChicago’s Successful Aging and Frailty Evaluation Clinic, said money is a major reason for the struggle. “I think probably the biggest driver is financial,” she said. “A lot of people are graduating medical school with really astronomical amounts of medical school loans.”

Geriatricians, like other doctors, carry a large debt – $200,000, on average, not counting undergraduate debt, according to the Association of American Medical Colleges.

But the typical geriatrician earns less than an internist or family medicine doctor who doesn’t undergo the additional year of training, Dr. Thompson said. “There’s not a lot of financial motivation to do this fellowship,” she said.

The jobs website Zippia reports that geriatricians earned roughly $165,000 per year on average in 2022. The average annual incomes in 2022 were $191,000 for pediatricians, $215,000 for family physicians, and $223,000 for internists, according to the site.

In other words, Dr. Harper said, “geriatrics is one of the few professions where you can actually do additional training and make less money.”

The reason for the pay issue is simple: Geriatricians treat patients covered by Medicare, whose reimbursement schedules lag behind those of commercial insurers. The Kaiser Family Foundation reported in 2020 that private insurance paid 143% of Medicare rates on average for physician services.

Dr. Harper said overall compensation for geriatricians has “not gained a lot of traction,” but they can earn comfortable livings.

Still, representation of the specialty on the American Medical Association’s Relative Value Scale Update Committee has led to approval by the Centers for Medicare & Medicaid Services of billing codes that pay geriatricians “for what they do. Examples include chronic care management, advance care planning, and dementia evaluation,” he said.

But the geriatrician gap goes beyond money.

Ageism, too, may play a role in residents not choosing geriatrics.

“Our culture is ageist. It definitely focuses on youth and looks at aging as being loss rather than just a change in what works well and what doesn’t work well,” said Mary Tinetti, MD, a geriatrician and researcher at Yale University, New Haven, Conn. “Ageism happens among physicians, just because they’re part of the broader society.”
 

Time for a new goal?

Dr. Tinetti said she’s optimistic that new ideas about geriatricians teaching other primary care clinicians about the tenets of geriatric medicine, which offer a wholistic approach to comorbidities, such as diabetes, atrial fibrillation, dementia, hypertension, hyperlipidemia, and polypharmacy problems faced by this population, especially those 85 and older.

She has called on her profession to abandon the goal of increasing the numbers of board-certified geriatricians – whom she refers to as big “G” geriatricians. She instead wants to develop a “small, elite workforce” that discovers and tests geriatrics principles through research, teaches these principles to all healthcare professions and to the public, and disseminates and implements the policies.

“We need a cadre of geriatricians who train all other clinicians in the care of older adults,” Dr. Tinetti said. “The goal is not more geriatricians but rather the preparation of all clinicians in the care of older adults.”

Dr. Thompson said geriatricians are teaching primary care specialists, nurses, social workers, and other health care providers the principles of age-friendly care. AGS has for the past 20 years led a program called the Geriatrics for Specialists Initiative to increase geriatrics knowledge and expertise of surgical and medical specialists.

Some specialties have taken the cue and have added geriatrics-related hyphens through additional training: geriatric-emergency, geriatric-general surgery, geriatric-hospitalists, and more.

HRSA runs programs to encourage physicians to train as geriatricians and geriatrics faculty, and it encourages the geriatrics interdisciplinary team approach.

Richard Olague, director of public affairs for HRSA, said his agency has invested over $160 million over the past 4 years in the education and training of geriatricians and other health care professionals who care for the elderly through its Geriatrics Workforce Enhancement Program and Geriatrics Academic Career Awards Program. In the academic year 2020-2021, the two programs trained 109 geriatricians; 456 other geriatric/gerontology providers and students; 44,450 other healthcare workforce professionals and students; and served 17,666 patients and 5,409 caregivers.

Dr. Harper, like his fellow geriatricians, tells young doctors that geriatrics is a fulfilling specialty.

“I get to care for the whole person and sometimes their families, too, and in the process form rich and meaningful relationships. And while I’m rarely in the position to cure, I always have the ability to care,” he said. “Sometimes that can mean being an advocate trying to make sure my patients receive the care they need, and other times it might mean protecting them from burdensome care that is unlikely to lead to any meaningful benefit. There is great reward in all of that.”

Dr. Supiano said geriatric patients are being helped by the Age-Friendly Health System initiative of the John A. Hartford Foundation and the Institute for Healthcare Improvement in partnership with the American Hospital Association and the Catholic Health Association of the United States. This is sort of a seal of approval for facilities committed to age-friendly care.

“When you go to your hospital, if they don’t have this age-friendly health system banner on the front door ... you either ask why that is not there, or you vote with your feet and go to another health system that is age friendly,” he said. “Geriatricians are eternal optimists.”

FDA alert: ‘Substantial’ hypocalcemia risk with denosumab use in dialysis patients

Article Type
Changed
Wed, 11/23/2022 - 11:16

The Food and Drug Administration issued an alert on Nov. 22 that cited preliminary evidence for a “substantial risk” for severe and symptomatic hypocalcemia and serious outcomes related to abnormally low calcium levels in people being treated with dialysis and receiving the osteoporosis medication denosumab (Prolia), including hospitalization and death.

In its alert, the FDA advised clinicians to make sure that people on dialysis who receive Prolia ingest adequate calcium and vitamin D supplementation and undergo frequent blood calcium monitoring, “possibly more often than is already being conducted,” which “may help decrease the likelihood or severity of these risks.”

The agency also called on clinicians to “advise patients on dialysis to immediately seek help if they experience symptoms of hypocalcemia,” such as unusual tingling or numbness in the hands, arms, legs, or feet; painful muscle spasms or cramps; voice box or lung spasms causing difficulty breathing; vomiting; seizures; or irregular heart rhythm.

The FDA had a similar message for people being treated with dialysis who are also receiving Prolia. The alert advised patients to watch for these symptoms and to tell their health care provider if they occur. The agency also advised patients who are undergoing dialysis and receiving Prolia to not stop the agent on their own, without first discussing this step with their care provider.

The FDA also advised providers and patients to contact the agency about episodes of side effects from Prolia (or other medications) via the FDA’s MedWatch program.
 

Frequent and serious

The FDA explained it issued the alert because of “the frequency and seriousness” of the risk for hypocalcemia and resulting complications. The agency noted that the risk seems most acute for people on dialysis who also receive Prolia, but the risk may also extend to people with advanced kidney disease who are not being treated with hemodialysis.

The alert stemmed from “interim results” in an ongoing safety study of Prolia that the FDA required the agent’s manufacturer, Amgen, to run when the agency first approved denosumab for U.S. marketing in 2010. The FDA said its review of these interim results suggested an increased risk of hypocalcemia with Prolia in patients with advanced kidney disease.

In addition, adverse event reports submitted to the FDA suggested in a separate, internal study that patients on dialysis treated with Prolia are at “substantial risk for severe and symptomatic hypocalcemia, including hospitalization and death.”

The alert explained that “because of the frequency and seriousness of these risks, we are alerting healthcare professionals and patients about them and that we are continuing to evaluate this potential safety issue with Prolia use in patients with advanced kidney disease, particularly those on dialysis.” The FDA added that “we will communicate our final conclusions and recommendations when we have completed our review or have more information to share.”

AAP issues clinical update to cerebral palsy guidelines

Article Type
Changed
Mon, 11/28/2022 - 10:46

Updated clinical guidelines for the early diagnosis and management of cerebral palsy have been issued by the American Academy of Pediatrics.

Coauthored with the American Academy for Cerebral Palsy and Developmental Medicine, the report builds on new evidence for improved care and outcomes since the 2006 consensus guidelines.

Cerebral palsy, the most common neuromotor disorder of childhood, is often accompanied by cognitive impairments, epilepsy, sensory impairments, behavioral problems, communication difficulties, breathing and sleep problems, gastrointestinal and nutritional problems, and bone and orthopedic problems.

In the United States, the estimated prevalence of cerebral palsy ranges from 1.5 to 4 per 1,000 live births.

“Early identification and initiation of evidence-based motor therapies can improve outcomes by taking advantage of the neuroplasticity in the infant brain,” said the guideline authors in an executive summary.

The guideline, published in Pediatrics, is directed to primary care physicians with pediatrics, family practice, or internal medicine training. “It’s a much more comprehensive overview of the important role that primary care providers play in the lifetime care of people with cerebral palsy,” explained Garey Noritz, MD, chair of the 2021-2022 Executive Committee of the Council on Children with Disabilities. Dr. Noritz, a professor of pediatrics at Ohio State University and division chief of the complex health care program at Nationwide Children’s Hospital, both in Columbus, said: “The combined efforts of the primary care physician and specialty providers are needed to achieve the best outcomes.”

The AAP recommends that primary care pediatricians, neonatologists, and other specialists caring for hospitalized newborns recognize those at high risk of cerebral palsy, diagnose them as early as possible, and promptly refer them for therapy. Primary care physicians are advised to identify motor delays early by formalizing standardized developmental surveillance and screening at 9, 18, and 30 months, and to implement family-centered care across multiple specialists.

“If a motor disorder is suspected, primary care physicians should simultaneously begin a medical evaluation, refer to a specialist for definitive diagnosis, and to therapists for treatment,” Dr. Noritz emphasized.

“The earlier any possible movement disorder is recognized and intervention begins, the better a child can develop a gait pattern and work toward living an independent life, said Manish N. Shah, MD, associate professor of pediatric neurosurgery at the University of Texas, Houston, who was not involved in developing the guidelines.

For children in whom physical therapy and medication have not reduced leg spasticity, a minimally invasive spinal procedure can help release contracted tendons and encourage independent walking. The optimal age for selective dorsal rhizotomy is about 4 years, said Dr. Shah, who is director of the Texas Comprehensive Spasticity Center at Children’s Memorial Hermann Hospital in Houston. “You can turn these children into walkers. As adults, they can get jobs, have their own families. It’s life-changing.”

Importantly, the guidelines address the health care disparities leading to a higher prevalence of cerebral palsy in Black children and in those from families with lower socioeconomic status. “Efforts to combat racism and eliminate barriers to culturally sensitive prenatal, perinatal, and later pediatric care may help to improve outcomes for all children with cerebral palsy,” the authors said.

“Every child with cerebral palsy needs an individual plan, but only 30% or 40% are getting interventions,” said Dr. Shah. The updated guidelines could help payers rethink the 15-20 visits a year that are often approved, compared with the 2-3 visits per week that are needed for speech, physical, and occupational therapy, he pointed out.

“Financial issues often compromise the interdisciplinary and coordinated care associated with favorable outcomes in children with cerebral palsy,” said Heidi Feldman, MD, PhD, a developmental and behavioral pediatric specialist at Stanford (Calif.) Medicine Children’s Health’s Johnson Center for Pregnancy and Newborn Services. “With a new guideline, there may be greater willingness to fund these essential services.”

In the meantime, the AAP recommends that pediatricians advise families about available medical, social, and educational services, such as early intervention services, the Title V Maternal and Child Health block grant program, and special education services through the public school system.

Children with cerebral palsy need the same standardized primary care as any child, including the full schedule of recommended vaccinations and vision and hearing testing. They also need to be monitored and treated for the many problems that commonly co-occur, including chronic pain.

When secondary complications arise, the frequency of visits should increase.

Pneumonia, the leading cause of death in children and adolescents with cerebral palsy, can be prevented or minimized through immunization against respiratory diseases and screening for signs and symptoms of aspiration and sleep-disordered breathing.

The AAP also recommends that symptoms or functional declines undergo full investigation into other potential causes.

Since the sedentary lifestyle associated with cerebral palsy is now known to be related to the higher rates of cardiovascular complications in this patient population, the AAP recommends more attention be paid to physical activity and a healthy diet early in life. Pediatricians are advised to help families locate suitable opportunities for adaptive sports and recreation.

Almost 50% of children and adolescents with cerebral palsy have intellectual disability, 60%-80% have difficulty speaking, and about 25% are nonverbal. To address this, pediatricians should maximize the use of augmentative and alternative communication devices and involve experts in speech and language pathology, according to the guidelines.

“Many individuals with cerebral palsy and severe motor limitations have active, creative minds, and may need assistive technology, such as electronic talking devices, to demonstrate that mental life,” said Dr. Feldman. “Primary care clinicians should advocate for assistive technology.”

For challenging behavior, especially in the patient with limited verbal skills, potential nonbehavioral culprits such as constipation, esophageal reflux disease, and musculoskeletal or dental pain must be ruled out.

In the lead-up to adolescence, youth with cerebral palsy must be prepared for puberty, menstruation, and healthy, safe sexual relationships, much like their nonaffected peers. Since a disproportionate number of children with cerebral palsy experience neglect and physical, sexual, and emotional abuse, however, family stressors should be identified and caregivers referred for support services.

For the transition from pediatric to adult health care, the AAP recommends that structured planning begin between 12 and 14 years of age. Before transfer, the pediatrician should prepare a comprehensive medical summary with the input of the patient, parent/guardian, and pediatric subspecialists.

Without a proper handoff, “there is an increased risk of morbidity, medical complications, unnecessary emergency department visits, hospitalizations, and procedures,” the authors warned.

Transitions are likely to run more smoothly when youth are given the opportunity to understand their medical condition and be involved in decisions about their health. With this in mind, the AAP recommends that pediatricians actively discourage overprotective parents from getting in the way of their child developing “maximal independence.”

No potential conflicts of interest were disclosed by the authors, Dr. Shah, or Dr. Feldman.

Sarilumab effective for polymyalgia rheumatica in phase 3 trial

– Treatment with the interleukin-6 receptor antagonist sarilumab (Kevzara), along with a 14-week taper of glucocorticoids, proved to have significant efficacy in patients with relapsing polymyalgia rheumatica (PMR) who were resistant to glucocorticoids in a phase 3 trial.

No new safety concerns were found with sarilumab in the multicenter, randomized, double-blind, placebo-controlled SAPHYR trial. Sarilumab is approved in the United States for the treatment of moderate to severe active rheumatoid arthritis in adults who have had an inadequate response or intolerance to one or more disease-modifying antirheumatic drugs.

The results, presented at the annual meeting of the American College of Rheumatology by Robert Spiera, MD, director of the Scleroderma, Vasculitis, and Myositis Center at the Hospital for Special Surgery in New York, included clinically meaningful improvement in quality-of-life scores.

The disease, which primarily affects people over age 65, can cause widespread aching and stiffness. It’s one of the most common inflammatory diseases among older adults.

PMR is relatively easy to treat with glucocorticoids, but relapses are common, which means long courses of glucocorticoid therapy and the side effects that come with them.
 

Need for a steroid-sparing therapy

“We recognize that a steroid-sparing drug in polymyalgia rheumatica seems to be an unmet need,” Dr. Spiera said at the meeting.

The trial, sponsored by Sanofi, included active, refractory PMR patients who flared within 3 months of study entry while on at least 7.5 mg/day of prednisone or the equivalent. They were randomly assigned (1:1) to 52 weeks of treatment with subcutaneous sarilumab 200 mg every 2 weeks plus the rapid 14-week glucocorticoid tapering regimen or were given placebo every 2 weeks plus a more traditional 52-week tapering of glucocorticoids.
 

COVID hampered recruitment

Recruitment was stopped early because of complications during the COVID-19 pandemic, so between October 2018 and July 2020, 118 of the intended 280 patients were recruited, and 117 were treated (sarilumab = 59, placebo = 58). Median age was 69 years in the treatment group and 70 among those taking placebo.

Of the 117 treated, only 78 patients (67%) completed treatment (sarilumab = 42, placebo = 36). The main reasons for stopping treatment were adverse events – including seven with sarilumab and four with placebo – and lack of efficacy (sarilumab = four, placebo = nine).

The primary outcome was the proportion of patients who reached sustained remission at 52 weeks, defined as disease remission by week 12 and no disease flare, normal C-reactive protein (CRP), and adherence to the glucocorticoid taper during weeks 12-52.

The researchers found that sustained remission was significantly higher in the sarilumab arm versus the control group (28.3% versus 10.3%; P = .0193).

IL-6 inhibitors lower CRP, but if you take CRP out of the definition, Dr. Spiera said, “we still saw this difference: 31.7% of patients treated with sarilumab and 13.8% treated with placebo and a longer taper achieved that endpoint.”
 

Forty-four percent lower risk of flare with sarilumab

Patients in the sarilumab group also had 44% lower risk of having a flare after achieving clinical remission versus the comparator group (16.7% versus 29.3%; hazard ratio, 0.56; 95% confidence interval, 0.35-0.90; P = .0153).

Patient-reported outcomes, which included physical and mental health scores and disability index results, favored sarilumab.

The incidence of treatment-emergent adverse events (TEAEs) was numerically higher in the sarilumab group, compared with the control group (94.9% versus 84.5%). TEAEs included neutropenia (15.3%) and arthralgia (15.3%) in the sarilumab group and insomnia (15.5%) in the comparator arm.

However, the frequency of serious AEs was higher in the control group, compared with the sarilumab arm (20.7% versus 13.6%). No deaths were reported, and, importantly in this age group treated with concurrent glucocorticoids and an IL-6 inhibitor, Dr. Spiera said, “there were no cases of diverticulitis requiring intervention.”

Dr. Spiera was asked about a seemingly low remission rate. He answered that the bar was very high for remission in this study.

Patients had to achieve remission by week 12 and with the rapid 14-week taper. “That means by week 12 the sarilumab arm patients were only on 2 mg of daily prednisone or its equivalent,” he said.

Patients had to maintain that for another 40 weeks, he noted, adding, “I think especially in the context of quality of life and function indices, these were important results.”

Dr. Sebastian E. Sattui

Sebastian E. Sattui, MD, director of the University of Pittsburgh Medical Center vasculitis clinic, told this news organization that prolonged use of glucocorticoids in patients with PMR remains an important concern and the need for other options is critical.

“Around 30% of patients with PMR remain on prednisone 5 years after diagnosis,” he said. “Low-dose glucocorticoids are still associated with significant morbidity. Until recently, there has been a paucity of high-quality data regarding the use of steroid-sparing agents in PMR. “

He noted that the SAPHYR trial data are promising “with sarilumab being successful in achieving remission while minimizing glucocorticoids in patients with relapsing PMR.” The clinically meaningful improvement in patient-reported outcomes was just as important, he added.

The main unanswered question is whether the disease-modifying ability of sarilumab will continue after it is stopped, Dr. Sattui said.

Dr. Spiera is a consultant for Sanofi, which funded the trial. He also disclosed financial relationships with GlaxoSmithKline, Boehringer Ingelheim, Corbus, InflaRx, AbbVie/Abbott, Novartis, Chemocentryx, Roche, and Vera. Dr. Sattui has received research support from AstraZeneca and has done unpaid consulting work for Sanofi.

Children with autism show distinct brain features related to motor impairment

Brain indicators of motor impairment were distinct among children with autism spectrum disorder (ASD), those with developmental coordination disorder (DCD), and controls, in a new study.

Previous research suggests that individuals with ASD overlap in motor impairment with those with DCD. But these two conditions may differ significantly in some areas, as children with ASD tend to show weaker skills in social motor tasks such as imitation, wrote Emil Kilroy, PhD, of the University of Southern California, Los Angeles, and colleagues.

The neurobiological basis of autism remains unknown, despite many research efforts, in part because of the heterogeneity of the disease, said corresponding author Lisa Aziz-Zadeh, PhD, also of the University of Southern California, in an interview.

Comorbidity with other disorders is a strong contributing factor to heterogeneity, and approximately 80% of autistic individuals have motor impairments and meet criteria for a diagnosis of DCD, said Dr. Aziz-Zadeh. “Controlling for other comorbidities, such as developmental coordination disorder, when trying to understand the neural basis of autism is important, so that we can understand which neural circuits are related to [core symptoms of autism] and which ones are related to motor impairments that are comorbid with autism, but not necessarily part of the core symptomology,” she explained. “We focused on white matter pathways here because many researchers now think the underlying basis of autism, besides genetics, is brain connectivity differences.”

In their study published in Scientific Reports, the researchers reviewed data from whole-brain correlational tractography for 22 individuals with autism spectrum disorder, 16 with developmental coordination disorder, and 21 normally developing individuals, who served as the control group. The mean age of the participants was approximately 11 years; the age range was 8-17 years.

Overall, patterns of brain diffusion (movement of fluid, mainly water molecules, in the brain) were significantly different in ASD children, compared with typically developing children.

The ASD group showed significantly reduced diffusivity in the bilateral fronto-parietal cingulum and the left parolfactory cingulum. This finding reflects previous studies suggesting an association between brain patterns in the cingulum area and ASD. But the current study is “the first to identify the fronto-parietal and the parolfactory portions of the cingulum as well as the anterior caudal u-fibers as specific to core ASD symptomatology and not related to motor-related comorbidity,” the researchers wrote.

Differences in brain diffusivity were associated with worse performance on motor skills and behavioral measures for children with ASD and children with DCD, compared with controls.

Motor development was assessed using the Total Movement Assessment Battery for Children-2 (MABC-2) and the Florida Apraxia Battery modified for children (FAB-M). The MABC-2 is among the most common tools for measuring motor skills and identifying clinically relevant motor deficits in children and teens aged 3-16 years. The test includes three subtest scores (manual dexterity, gross-motor aiming and catching, and balance) and a total score. Scores are based on a child’s best performance on each component, and higher scores indicate better functioning. In the new study, The MABC-2 total scores averaged 10.57 for controls, compared with 5.76 in the ASD group, and 4.31 in the DCD group.

Children with ASD differed from the other groups in social measures. Social skills were measured using several tools, including the Social Responsivity Scale (SRS Total), which is a parent-completed survey that includes a total score designed to reflect the severity of social deficits in ASD. It is divided into five subscales for parents to assess a child’s social skill impairment: social awareness, social cognition, social communication, social motivation, and mannerisms. Scores for the SRS are calculated in T-scores, in which a score of 50 represents the mean. T-scores of 59 and below are generally not associated with ASD, and patients with these scores are considered to have low to no symptomatology. Scores on the SRS Total in the new study were 45.95, 77.45, and 55.81 for the controls, ASD group, and DCD group, respectively.
 

 

 

Results should raise awareness

“The results were largely predicted in our hypotheses – that we would find specific white matter pathways in autism that would differ from [what we saw in typically developing patients and those with DCD], and that diffusivity in ASD would be related to socioemotional differences,” Dr. Aziz-Zadeh said, in an interview.

“What was surprising was that some pathways that had previously been thought to be different in autism were also compromised in DCD, indicating that they were common to motor deficits which both groups shared, not to core autism symptomology,” she noted.

A message for clinicians from the study is that a dual diagnosis of DCD is often missing in ASD practice, said Dr. Aziz-Zadeh. “Given that approximately 80% of children with ASD have DCD, testing for DCD and addressing potential motor issues should be more common practice,” she said.

Dr. Aziz-Zadeh and colleagues are now investigating relationships between the brain, behavior, and the gut microbiome. “We think that understanding autism from a full-body perspective, examining interactions between the brain and the body, will be an important step in this field,” she emphasized.

The study was limited by several factors, including the small sample size, the use of only right-handed participants, and the use of self-reports by children and parents, the researchers noted. Additionally, they noted that white matter develops at different rates in different age groups, and future studies might consider age as a factor, as well as further behavioral assessments, they said.
 

Small sample size limits conclusions

“Understanding the neuroanatomic differences that may contribute to the core symptoms of ASD is a very important goal for the field, particularly how they relate to other comorbid symptoms and neurodevelopmental disorders,” said Michael Gandal, MD, of the department of psychiatry at the University of Pennsylvania, Philadelphia, and a member of the Lifespan Brain Institute at the Children’s Hospital of Philadelphia, in an interview.

“While this study provides some clues into how structural connectivity may relate to motor coordination in ASD, it will be important to replicate these findings in a much larger sample before we can really appreciate how robust these findings are and how well they generalize to the broader ASD population,” Dr. Gandal emphasized.

The study was supported by the Eunice Kennedy Shriver National Institute of Child Health and Human Development. The researchers had no financial conflicts to disclose. Dr. Gandal had no financial conflicts to disclose.

But the current study is “the first to identify the fronto-parietal and the parolfactory portions of the cingulum as well as the anterior caudal u-fibers as specific to core ASD symptomatology and not related to motor-related comorbidity,” the researchers wrote.

Differences in brain diffusivity were associated with worse performance on motor skills and behavioral measures for children with ASD and children with DCD, compared with controls.

Motor development was assessed using the Total Movement Assessment Battery for Children-2 (MABC-2) and the Florida Apraxia Battery modified for children (FAB-M). The MABC-2 is among the most common tools for measuring motor skills and identifying clinically relevant motor deficits in children and teens aged 3-16 years. The test includes three subtest scores (manual dexterity, gross-motor aiming and catching, and balance) and a total score. Scores are based on a child’s best performance on each component, and higher scores indicate better functioning. In the new study, The MABC-2 total scores averaged 10.57 for controls, compared with 5.76 in the ASD group, and 4.31 in the DCD group.

Children with ASD differed from the other groups in social measures. Social skills were measured using several tools, including the Social Responsivity Scale (SRS Total), which is a parent-completed survey that includes a total score designed to reflect the severity of social deficits in ASD. It is divided into five subscales for parents to assess a child’s social skill impairment: social awareness, social cognition, social communication, social motivation, and mannerisms. Scores for the SRS are calculated in T-scores, in which a score of 50 represents the mean. T-scores of 59 and below are generally not associated with ASD, and patients with these scores are considered to have low to no symptomatology. Scores on the SRS Total in the new study were 45.95, 77.45, and 55.81 for the controls, ASD group, and DCD group, respectively.
 

 

 

Results should raise awareness

“The results were largely predicted in our hypotheses – that we would find specific white matter pathways in autism that would differ from [what we saw in typically developing patients and those with DCD], and that diffusivity in ASD would be related to socioemotional differences,” Dr. Aziz-Zadeh said, in an interview.

“What was surprising was that some pathways that had previously been thought to be different in autism were also compromised in DCD, indicating that they were common to motor deficits which both groups shared, not to core autism symptomology,” she noted.

A message for clinicians from the study is that a dual diagnosis of DCD is often missing in ASD practice, said Dr. Aziz-Zadeh. “Given that approximately 80% of children with ASD have DCD, testing for DCD and addressing potential motor issues should be more common practice,” she said.

Dr. Aziz-Zadeh and colleagues are now investigating relationships between the brain, behavior, and the gut microbiome. “We think that understanding autism from a full-body perspective, examining interactions between the brain and the body, will be an important step in this field,” she emphasized.

The study was limited by several factors, including the small sample size, the use of only right-handed participants, and the use of self-reports by children and parents, the researchers noted. Additionally, they noted that white matter develops at different rates in different age groups, and future studies might consider age as a factor, as well as further behavioral assessments, they said.
 

Small sample size limits conclusions

“Understanding the neuroanatomic differences that may contribute to the core symptoms of ASD is a very important goal for the field, particularly how they relate to other comorbid symptoms and neurodevelopmental disorders,” said Michael Gandal, MD, of the department of psychiatry at the University of Pennsylvania, Philadelphia, and a member of the Lifespan Brain Institute at the Children’s Hospital of Philadelphia, in an interview.

“While this study provides some clues into how structural connectivity may relate to motor coordination in ASD, it will be important to replicate these findings in a much larger sample before we can really appreciate how robust these findings are and how well they generalize to the broader ASD population,” Dr. Gandal emphasized.

The study was supported by the Eunice Kennedy Shriver National Institute of Child Health and Human Development. The researchers had no financial conflicts to disclose. Dr. Gandal had no financial conflicts to disclose.

First classification criteria proposed for chronic osteomyelitis

Article Type
Changed
Fri, 11/18/2022 - 15:07

– An international group of researchers has proposed the first classification criteria for chronic nonbacterial osteomyelitis (CNO) and a severe form of it, chronic recurrent multifocal osteomyelitis (CRMO).

CNO/CRMO most frequently affect children and adolescents and can significantly affect quality of life.

Dr. Yongdong (Dan) Zhao

Yongdong (Dan) Zhao, MD, PhD, a pediatric rheumatologist at Seattle Children’s Hospital, Seattle, Washington, and Seza Ozen, MD, MSc, medical faculty head at Hacettepe University in Ankara, Turkey – members of the expert panel for criteria development – explained the proposed criteria, developed over 6 years, at the American College of Rheumatology 2022 Annual Meeting.

They gave examples of the point system that will help researchers correctly classify CNO/CRMO if the criteria are approved by ACR and the European Alliance of Associations for Rheumatology (EULAR).

Dr. Melissa S. Oliver

Melissa S. Oliver, MD, a pediatric rheumatologist at Riley Children’s Hospital and Indiana University, Indianapolis, told this news organization: “This proposal is important because CNO/CRMO has primarily been a diagnosis of exclusion. There are no specific tests or biomarkers for this disease. It can mimic malignancy and infectious osteomyelitis in its presentation, and these must be ruled out thoroughly first.”

However, she noted, this can be challenging and can delay diagnosis and treatment.

The classification criteria are novel, she said, because an international collaborative group used a consensus process involving physicians managing CNO and patients or caregivers of children with CNO.
 

Findings for and against CNO

Dr. Ozen summarized some examples of findings for and against a CNO/CRMO classification.

Statistically significant findings in favor of CNO/CRMO, she said, include intermittent bone pain; bone pain in upper torso; swelling of upper torso; presence of symmetric lesions; and presence of adaptive immune cell and/or fibrosis in biopsy.

Conversely, findings against CNO/CRMO include fever; signs of infection by labs; signs of cancer by biopsy; specific abnormal x-ray/CT scan; specific abnormal MRI; or pain resolved with antibiotics alone.

Dr. Zhao described a point system with a threshold of 55 points for classification of CNO/CRMO.

He gave actual examples from the registry to demonstrate high and low probability of CNO/CRMO.
 

Pro-CNO example

The first was a boy, aged 7 years 10 months, who had a year and a half of pain in his back and legs, but no fever. Pain was constant, waxing and waning. He had a personal and family history of psoriasis and was tender to palpation at multiple sites. Labs were normal and bone biopsy and vitamin C tests were not done; imaging findings showed multiple bones were affected. There was no antibiotic treatment.

That patient was scored 81, much higher than the threshold of 55, and would be classified as having CNO.
 

Non-CNO example

Conversely, the following example of a patient would score 47 – under the threshold – and would not be classified as having CNO.

That patient was an 11-year-old boy who had 2 months of pain in his right thigh with no fever. The pain was constantly waxing and waning. He was tender to palpation at only his right thigh without swelling. Labs were normal. He had no coexisting conditions. Erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) were not measured, and no vitamin C test was performed. Imaging showed one right femur lesion on a PET-CT scan. There was no antibiotic treatment, and a bone biopsy culture showed malignancy but no inflammation or fibrosis.

Dr. Zhao said the mimickers most likely to be misclassified are vitamin C deficiency; hypophosphatasia; benign bone tumor, such as osteogenic osteoma; and a malignancy with normal labs and multifocal pattern of bone lesions.

The classification criteria will be “extremely helpful to diagnose patients with CNO/CRMO earlier,” said Dr. Oliver, who helped develop the criteria.

“The goal is that the proposed classification criteria will be used by all physicians to diagnose suspected CNO patients earlier and refer to a rheumatologist earlier so that appropriate therapies will not be delayed.”

The group will seek ACR and EULAR endorsement, and if granted, work toward widespread implementation. The criteria will allow researchers to have a more homogeneous study population for future clinical trials, Dr. Zhao said.

Dr. Zhao, Dr. Ozen, and Dr. Oliver declared no relevant financial relationships. Dr. Oliver helped develop the proposed guidelines.

Combination therapy may boost remission in JIA

Article Type

Tue, 11/15/2022 - 12:58

Benefit endures at 3 years

– Aggressive therapy using conventional synthetic disease-modifying antirheumatic drugs (DMARDs) in combination with biologic agents early, soon after a child is diagnosed with polyarticular juvenile idiopathic arthritis (pJIA), enabled more patients to achieve clinical remission and longer times in inactive disease than more conventional therapeutic approaches, 3-year results of prospective, observational study demonstrated.

The results of The Childhood Arthritis and Rheumatology Research Alliance STOP-JIA study, which Yukiko Kimura, MD, presented at the annual meeting of the American College of Rheumatology, showed early combination therapy had benefits, compared with other treatment strategies that were more evident at 3 years than at 1 year of study.

Dr. Yukiko Kimura

“The STOP-JIA study showed that, after 3 years, patients who started a biologic early on in combination with methotrexate spent more time in inactive disease and achieved clinical remission more often when compared to those started on traditional step-up therapy,” Dr. Kimura, chief of pediatric rheumatology at Hackensack (N.J.) Meridian Health and professor of pediatrics at the Hackensack Meridian School of Medicine, said at a press conference. “This study shows that the treatment of poly-JIA patients receive initially very early on in their disease matters even 3 years after that treatment was started.”

The study compared three CARRA consensus treatment plans (CTP) for untreated pediatric pJIA patients: step-up (SU) – starting conventional synthetic DMARD therapy and adding a biologic if needed after 3 or more months; early-combination (EC) therapy – starting synthetic and biologic DMARDs together; and biologic first (BF) therapy – starting biologic DMARD monotherapy.

Dr. Kimura explained the rationale for the study. “Since biologic treatments were introduced more than 20 years ago, the prognosis for JIA significantly improved. These very effective medicines often work wonders, quickly reducing pain and inflammation in joint disease activity,” she said in the press conference. “What is not known, however, is when is the best time to start these very effective treatments.”

The most common approach is to start with a synthetic DMARD, typically methotrexate, and wait before starting a biologic, Dr. Kimura said.

“But even though methotrexate can work very well by itself, it does not work for every patient, and we don’t know whether waiting months for it to work and then starting a biologic might potentially lessen their effectiveness,” Dr. Kimura added. “We don’t know if there’s a window of opportunity that’s lost while waiting to see whether methotrexate will work.”



The study originally enrolled 400 patients, 297 of whom completed the 3-year visit – 190 in SU, 76 in EC and 31 in BF. At 12 months, the study found no statistically significant difference in clinically inactive disease (CID) between the groups, Dr. Kimura said.

Even at the 3-year visit, the percentage of patients in CID off glucocorticoids and clinical Juvenile Arthritis Disease Activity Score based on 10 joints inactive disease (cJADAS 10 ID) did not differ among the three groups, Dr. Kimura said in presenting the results. “But,” she added, “greater proportions of early-combination CTP group were able to achieve clinical remissions and spend more time with inactive disease in both CID and cJADAS 10.”

A closer look at the outcomes showed some separation between early-combination therapy and the other two treatment plans. The incidence of clinical remission (at any time point over 36 months) was 67.1% in the EC group vs. 49.1% and 47.3%, respectively, in the BF and SU groups, Dr. Kimura said. “The difference between the early-combination and step-up groups was highly significant [P = .007],” she added.

EC also had an edge in the percentage of time patients spent in CID (over 36 months): 39.2% versus 32% and 27.4%, respectively, in the BF and SU groups (P = .006 for EV vs. SU), as well as cJADAS 10 ID (50.6% in EC group vs. 42.8% and 37.5%, respectively in the BF and SU groups; P = .005 for EC vs. SU).

Dr. Kimura said that the STOP JIA trial will continue with longer-term analysis and ongoing monitoring of study patients through the CARRA registry. “These longer-term analyses and readouts will be important because even though the results at 12 months didn’t seem as definitive, it seems the longer we go, the more impact we see of the treatments that were started early on in this disease.”

Dr. Nina T. Washington

The findings from this study are “significantly important,” Nina T. Washington, MD, MPH, a pediatric rheumatologist at the University of New Mexico Hospital, Albuquerque, and the Mary Bridge Children’s Hospital in Tacoma, Wash., said in an interview. “At least for the past decade we’ve really been advocating towards earlier and aggressive therapy, and that’s what this study shows: the sooner you can treat this disease, the sooner you can attack those joints that are inflamed, the better outcome you give the patient.”

The study also confirms that pediatric rheumatologists are not overtreating patients with pJIA, she added.

“In a sense we’re actually treating and preventing and if you have a child that has arthritis, it’s okay to treat that child,” Dr. Washington said. “For me that’s the most reassuring thing: that I’m not necessarily going overboard. If I have a child with polyarticular JIA and they have multiple inflamed joints and I have the evidence as they’re sitting in front of me, and I treat them. I’m going to give them the best outcome.”

The Patient Centered Outcomes Research Institute provided study funding. Dr. Kimura is chair of the CARRA JIA disease research committee and cochair of the CARRA Registry and Research Oversight Committee. She disclosed a financial relationship with Genentech. Dr. Washington has no relevant relationships to disclose.

EC also had an edge in the percentage of time patients spent in CID (over 36 months): 39.2% versus 32% and 27.4%, respectively, in the BF and SU groups (P = .006 for EV vs. SU), as well as cJADAS 10 ID (50.6% in EC group vs. 42.8% and 37.5%, respectively in the BF and SU groups; P = .005 for EC vs. SU).

Dr. Kimura said that the STOP JIA trial will continue with longer-term analysis and ongoing monitoring of study patients through the CARRA registry. “These longer-term analyses and readouts will be important because even though the results at 12 months didn’t seem as definitive, it seems the longer we go, the more impact we see of the treatments that were started early on in this disease.”

Dr. Nina T. Washington

The findings from this study are “significantly important,” Nina T. Washington, MD, MPH, a pediatric rheumatologist at the University of New Mexico Hospital, Albuquerque, and the Mary Bridge Children’s Hospital in Tacoma, Wash., said in an interview. “At least for the past decade we’ve really been advocating towards earlier and aggressive therapy, and that’s what this study shows: the sooner you can treat this disease, the sooner you can attack those joints that are inflamed, the better outcome you give the patient.”

The study also confirms that pediatric rheumatologists are not overtreating patients with pJIA, she added.

“In a sense we’re actually treating and preventing and if you have a child that has arthritis, it’s okay to treat that child,” Dr. Washington said. “For me that’s the most reassuring thing: that I’m not necessarily going overboard. If I have a child with polyarticular JIA and they have multiple inflamed joints and I have the evidence as they’re sitting in front of me, and I treat them. I’m going to give them the best outcome.”

The Patient Centered Outcomes Research Institute provided study funding. Dr. Kimura is chair of the CARRA JIA disease research committee and cochair of the CARRA Registry and Research Oversight Committee. She disclosed a financial relationship with Genentech. Dr. Washington has no relevant relationships to disclose.

Total replacement and fusion yield similar outcomes for ankle osteoarthritis

Adults who underwent either total ankle replacement or ankle fusion for end-stage ankle osteoarthritis showed similar clinical scores and adverse event numbers, in a randomized controlled trial of approximately 300 patients.

Ankle osteoarthritis remains a cause of severe pain and disability. Patients are treated nonoperatively if possible, but surgery is often needed for individuals with end-stage disease, wrote Andrew Goldberg, MBBS, of University College London and colleagues in the Annals of Internal Medicine.

“Most patients with ankle arthritis respond to nonoperative treatments, such as weight loss, activity modification, support braces, and analgesia, [but] once the disease has progressed to end-stage osteoarthritis, the main surgical treatments are total ankle re-placement or ankle arthrodesis,” Dr. Goldberg said, in an interview.

In the new study, patients were randomized to receive either a total ankle replacement (TAR) or ankle fusion (AF).

“We showed that, in both treatment groups the clinical scores improved hugely, by more than three times the minimal clinically important difference,” Dr. Goldberg said in an interview.

“Although the ankle replacement arm improved, on average, by more than an extra 4 points over ankle fusion, this was not considered clinically or statistically significant,” he said.

The study is the first randomized trial to show high-quality and robust results, he noted, and findings support data from previous studies.

“Although both TAR and ankle fusion have been shown to be effective, they are very different treatments, with one fusing the bones so that there is no ankle joint movement, and the other replacing the joint with the aim of retaining ankle joint movement. It is difficult for a patient to know which treatment is more suitable for them, with most seeking guidance from their surgeon,” he said.

Generating high-quality evidence

The study, a randomized, multicenter, open-label trial known as TARVA (Total Ankle Replacement Versus Ankle Arthrodesis), aimed to compare the clinical effectiveness of the two existing publicly funded U.K. treatment options, the authors wrote.

Patients were recruited at 17 U.K. centers between March 6, 2015, and Jan. 10, 2019. The study enrolled 303 adults aged 50-85 years with end-stage ankle osteoarthritis. The mean age of the participants was 68 years; 71% were men. A total of 137 TAR patients and 144 ankle fusion patients completed their surgeries with clinical scores available for analysis. Baseline characteristics were mainly similar between the groups.

Blinding was not possible because of the nature of the procedures, but the surgeons who screened the patients were not aware of the randomization allocations, the researchers noted. A total of 33 surgeons participated in the trial, with a median number of seven patients per surgeon during the study period.

For TAR, U.K. surgeons use both two-component, fixed-bearing and three-component, mobile-bearing implants, the authors write. Ankle fusion was done using the surgeon’s usual technique of either arthroscopic-assisted or open ankle fusion.

The primary outcome was the change in the Manchester–Oxford Foot Questionnaire walking/standing (MOXFQ-W/S) domain scores from baseline to 52 weeks after surgery. The MOXFQ-W/S uses a scale of 0-100, with lower scores representing better outcomes. Secondary outcomes included change in the MOXFQ-W/S scores at 26 weeks after surgery, as well as measures of patient quality of life.

 

 

No statistically significant difference

Overall, the mean MOXFQ-W/S scores improved significantly from baseline to 52 weeks for both groups, with average improvements of 49.9 in the TAR group and 44.4 points in the AF group. The average scores at 52 weeks were 31.4 in the TAR group and 36.8 in the AF group.

The adjusted difference in score change from baseline was –5.56, showing a slightly greater degree of improvement with TAR, but this difference was not clinically or statistically significant, the researchers noted.

Adverse event numbers were similar for both procedures, with 54% of TAR patients and 53% of AF patients experiencing at least 1 adverse event during the study period. Of those, 18% of TAR patients and 24% of AF patients experienced at least 1 serious adverse event.

However, the TAR patients experienced a higher rate of wound healing complications and nerve injuries, while thromboembolism was higher in the AF patients, the researchers noted.

A prespecified subgroup analysis of patients with osteoarthritis in adjacent joints suggested a greater improvement in TAR, compared with AF, a difference that increased when fixed-bearing TAR was compared with AF, the authors wrote.

“This reinforces previous reports that suggest that the presence of adjacent joint arthritis may be an indication for ankle replacement over AF,” the authors wrote in their discussion.

“Many of these patients did not have any symptoms in the adjacent joints,” they noted.

“The presence of adjacent joint arthritis, meaning the wear and tear of the joints around the ankle joint, seemed to favor ankle replacement,” Dr. Goldberg said. Approximately 30 joints in the foot continue to move after the ankle is fused, and if these adjacent joints are not healthy before surgery [as was the case in 42% of the study patients], the results of fusion were less successful, he explained.

A post hoc analysis between TAR subtypes showed that patients who had fixed-bearing TAR had significantly greater improvements, compared with AF patients, but this difference was not observed in patients who had mobile-bearing TAR, the researchers noted.

Dr. Goldberg said it was surprising “that, in a separate analysis, we found that the fixed-bearing ankle replacement patients [who accounted for half of the implants used] improved by a much greater difference when compared to ankle fusion.”

The study findings were limited by several factors including the short follow-up and study design that allowed surgeons to choose any implant and technique, the researchers noted.

Other limitations include a lack of data on cost-effectiveness and the impact of comorbidities on outcomes, they wrote. However, the study is the first completed multicenter randomized controlled trial to compare TAR and AF procedures for end-stage ankle osteoarthritis and shows that both yield similar clinical improvements, they concluded.

Data can inform treatment discussion

The take-home messages for clinicians are that both ankle replacement and ankle fusion are effective treatments that improve patients’ quality of life, and it is important to establish the health of adjacent joints before making treatment recommendations, Dr. Goldberg said.

“Careful counseling on the relative risks of each procedure should be part of the informed consent process,” he added. Ideally, all patients seeking surgical care for ankle arthritis should have a choice between ankle replacement and ankle fusion, but sometimes there is inequity of provision of the two treatments, he noted.

“We now encourage all surgeons to work in ankle arthritis networks so that every patient, no matter where they live, can have choice about the best treatment for them,” he said.

 

 

Researchers met the challenge of surgical RCT

Randomized trials of surgical interventions are challenging to conduct, and therefore limited, wrote Bruce Sangeorzan, MD, of the University of Washington, Seattle, and colleagues in an accompanying editorial. However, the new study was strengthened by the inclusion of 17 centers for heterogeneity of implant type and surgeon experience level, the editorialists said in the Annals of Internal Medicine.

The study is especially important, because ankle arthritis treatment is very understudied, compared with hip and knee arthritis, but it has a similar impact on activity, editorial coauthor Dr. Sangeorzan said in an interview.

“Randomized controlled trials are the gold standard for comparing medical therapies,” he said, “but they are very difficult to do in surgical treatments, particularly when the two treatments can be differentiated, in this case by movement of the ankle.”

In addition, there is a strong placebo effect attached to interventions, Dr. Sangeorzan noted. “Determining best-case treatment relies on prospective research, preferably randomized. Since both ankle fusion and ankle replacement are effective therapies, a prospective randomized trial is the best way to help make treatment decisions,” he said.

The current study findings are not surprising, but they are preliminary, and 1 year of follow-up is not enough to determine effectiveness, Dr. Sangeorzan emphasized. However, “the authors have done the hard work of randomizing the patients and collecting the data, and the patients can now be followed for a longer time,” he said.

“In addition, the trial was designed with multiple secondary outcome measures, so the data can be matched up with larger trials that were not randomized to identify key elements of success for each procedure,” he noted.

The key message for clinicians is that ankle arthritis has a significant impact on patients’ lives, but there are two effective treatments that can reduce the impact of the disease, said Dr. Sangeorzan. “The data suggest that there are differences in implant design and differences in comorbidities that should influence decision-making,” he added.

Additional research is needed in the form of a longer study duration with larger cohorts, said Dr. Sangeorzan. In particular, researchers need to determine what comorbidities might drive patients to one type of care vs. another, he said. “The suggestion that [patients receiving implants with two motion segments have better outcomes than those receiving implants with a one-motion segment] also deserves further study,” he added.

The research was supported by the UK National Institute for Health and Care Research Health Technology Assessment Programme. The trial was sponsored by University College London. Dr. Goldberg disclosed grant support from NIHR HTA, as well as financial relationships with companies including Stryker, Paragon 28, and stock options with Standing CT Company, Elstree Waterfront Outpatients, and X Bolt Orthopedics.

The editorialists had no financial conflicts to disclose.
