Pain

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.

A 70-year-old man with a history of coronary artery disease (CAD) is seen for concerns about erectile dysfunction (ED). He is requesting sildenafil. He has stable angina, having chest pain with exercise. He uses sublingual nitroglycerin (SL NTG prn) about three times a month. His blood pressure is 140/70 mm Hg. His pulse is 60 beats per minute. His current medications are lisinopril, atorvastatin, aspirin, and SL NTG tablets as needed.

What would you recommend?

A. No sildenafil; refer to urologist for other ED options.

B. Okay to use sildenafil if greater than 6 hours from NTG use.

C. Recommend tadalafil.

Is coprescribing nitrates and phosphodiesterase inhibitors safe?

The FDA warns against the use of phosphodiesterase inhibitors in patients taking nitrates. Combining nitrates with phosphodiesterase type 5 (PDE5) inhibitors is contraindicated because of a synergistic blood pressure lowering effect.¹ This warning/contraindication was based on theoretical concerns, as well as concern that of the first 130 deaths reported in patients who took sildenafil, 16 of the patients also were taking nitrates.²

Parker and colleagues studied the safety of giving IV nitroglycerin to patients with coronary artery disease (CAD) who have taken sildenafil.³ The study was a randomized, placebo-controlled, crossover trial. Participants received sildenafil 100 mg or placebo, then received intravenous NTG. Patients who received sildenafil had a 4-6 mm Hg systolic BP drop compared with those who took the placebo. There was no difference in severe events between the sildenafil and placebo groups. The blood levels of nitroglycerin in this study were very likely much higher than the levels that occur with SL NTG.

A recent study by Holt et al. looked at overall cardiovascular outcomes with coprescribing nitrates and phosphodiesterase inhibitors.⁴ The study was a case crossover design, using a nationwide Danish health registry over the period of 2000-2018. In 2000, the rate of coprescribing of phosphodiesterase inhibitors in ischemic heart disease patients on nitrates was .9 per 100 persons/year and rose to 19.5 prescriptions per 100 persons/year in 2018. During this same time, no statistically significant association was found between the coprescription of nitrates with PDE5 inhibitors and the risk for MI, cardiac arrest, syncope, stroke, or an adverse drug event.
 

Does nitroglycerin response help determine cause of chest pain?

Nitroglycerin response has long been used as a clinical indicator on whether a patient’s chest pain is cardiac or not. Eric A. Shry, MD, and his colleagues looked at the usefulness of nitroglycerin response in the treatment of chest pain as a predictor of ischemic chest pain in an emergency department setting.⁵

The study was a retrospective review of 223 patients who presented to the emergency department over a 5-month period with ongoing chest pain. They looked at patients who had ongoing chest pain in the emergency department, received nitroglycerin, and did not receive any therapy other than aspirin within 10 minutes of receiving nitroglycerin. Response to the drug was compared with the final diagnosis of cardiac versus noncardiac chest pain.

Of the patients with a final determination of cardiac chest pain, 88% had a nitroglycerin response, whereas 92% of the patients with noncardiac chest pain had a nitroglycerin response (P = .50).

Deborah B. Diercks, MD, and her colleagues looked at improvement in chest pain scores in the emergency department in patients treated with nitroglycerin and whether it correlated with a cardiac etiology of chest pain.⁶ The study was a prospective, observational study of 664 patients in an urban tertiary care emergency department over a 16-month period. An 11-point numeric chest pain scale was assessed and recorded by research assistants before and 5 minutes after receiving nitroglycerin. The scale ranged from 0 (no pain) to 10 (worst pain imaginable).

A final diagnosis of a cardiac etiology for chest pain was found in 18% of the patients in the study. Of the patients who had cardiac-related chest pain, 20% had no reduction in pain with nitroglycerin, compared with 19% of the patients without cardiac-related chest pain.

A complete or significant reduction in chest pain occurred with nitroglycerin in 31% of patients with cardiac chest pain and 27% of the patients without cardiac chest pain (P = .76).

Nitroglycerin response does not appear to be helpful in distinguishing cardiac from noncardiac chest pain, but a study by His and colleagues offers an interesting twist.⁷

The authors of this research studied 118 patients looking to see if the side effect of headache with nitroglycerin was more common in patients who did not have CAD than in those who did. All the patients had a varying degree of relief of chest pain with NTG administration within 10 minutes. In patients with normal coronary arteries or minimal CAD, 73% had headache caused by NTG, whereas in patients with obstructive CAD, only 23% had headache after NTG use.
 

Take-home messages

• Short acting nitroglycerin may not be a contraindication for phosphodiesterase inhibitor use.
• More data are still needed.
• Nitroglycerin response does not help distinguish chest pain from CAD from noncardiac causes.

Is coprescribing nitrates and phosphodiesterase inhibitors safe?

The FDA warns against the use of phosphodiesterase inhibitors in patients taking nitrates. Combining nitrates with phosphodiesterase type 5 (PDE5) inhibitors is contraindicated because of a synergistic blood pressure lowering effect.¹ This warning/contraindication was based on theoretical concerns, as well as concern that of the first 130 deaths reported in patients who took sildenafil, 16 of the patients also were taking nitrates.²

Parker and colleagues studied the safety of giving IV nitroglycerin to patients with coronary artery disease (CAD) who have taken sildenafil.³ The study was a randomized, placebo-controlled, crossover trial. Participants received sildenafil 100 mg or placebo, then received intravenous NTG. Patients who received sildenafil had a 4-6 mm Hg systolic BP drop compared with those who took the placebo. There was no difference in severe events between the sildenafil and placebo groups. The blood levels of nitroglycerin in this study were very likely much higher than the levels that occur with SL NTG.

A recent study by Holt et al. looked at overall cardiovascular outcomes with coprescribing nitrates and phosphodiesterase inhibitors.⁴ The study was a case crossover design, using a nationwide Danish health registry over the period of 2000-2018. In 2000, the rate of coprescribing of phosphodiesterase inhibitors in ischemic heart disease patients on nitrates was .9 per 100 persons/year and rose to 19.5 prescriptions per 100 persons/year in 2018. During this same time, no statistically significant association was found between the coprescription of nitrates with PDE5 inhibitors and the risk for MI, cardiac arrest, syncope, stroke, or an adverse drug event.
 

Does nitroglycerin response help determine cause of chest pain?

Nitroglycerin response has long been used as a clinical indicator on whether a patient’s chest pain is cardiac or not. Eric A. Shry, MD, and his colleagues looked at the usefulness of nitroglycerin response in the treatment of chest pain as a predictor of ischemic chest pain in an emergency department setting.⁵

The study was a retrospective review of 223 patients who presented to the emergency department over a 5-month period with ongoing chest pain. They looked at patients who had ongoing chest pain in the emergency department, received nitroglycerin, and did not receive any therapy other than aspirin within 10 minutes of receiving nitroglycerin. Response to the drug was compared with the final diagnosis of cardiac versus noncardiac chest pain.

Of the patients with a final determination of cardiac chest pain, 88% had a nitroglycerin response, whereas 92% of the patients with noncardiac chest pain had a nitroglycerin response (P = .50).

Deborah B. Diercks, MD, and her colleagues looked at improvement in chest pain scores in the emergency department in patients treated with nitroglycerin and whether it correlated with a cardiac etiology of chest pain.⁶ The study was a prospective, observational study of 664 patients in an urban tertiary care emergency department over a 16-month period. An 11-point numeric chest pain scale was assessed and recorded by research assistants before and 5 minutes after receiving nitroglycerin. The scale ranged from 0 (no pain) to 10 (worst pain imaginable).

A final diagnosis of a cardiac etiology for chest pain was found in 18% of the patients in the study. Of the patients who had cardiac-related chest pain, 20% had no reduction in pain with nitroglycerin, compared with 19% of the patients without cardiac-related chest pain.

A complete or significant reduction in chest pain occurred with nitroglycerin in 31% of patients with cardiac chest pain and 27% of the patients without cardiac chest pain (P = .76).

Nitroglycerin response does not appear to be helpful in distinguishing cardiac from noncardiac chest pain, but a study by His and colleagues offers an interesting twist.⁷

The authors of this research studied 118 patients looking to see if the side effect of headache with nitroglycerin was more common in patients who did not have CAD than in those who did. All the patients had a varying degree of relief of chest pain with NTG administration within 10 minutes. In patients with normal coronary arteries or minimal CAD, 73% had headache caused by NTG, whereas in patients with obstructive CAD, only 23% had headache after NTG use.
 

Take-home messages

• Short acting nitroglycerin may not be a contraindication for phosphodiesterase inhibitor use.
• More data are still needed.
• Nitroglycerin response does not help distinguish chest pain from CAD from noncardiac causes.

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.”

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.”

This combination of vascular features with excess keratin fit perfectly with the name of the diagnosis: angiokeratoma. The dark color of the lesion on magnification, or in this case with dermoscopy, showed the lacunar pattern of dilated vessels. The overlying keratin was likely accentuated because it was on an extensor surface; the rim of hyperpigmentation is common for these lesions.

Angiokeratomas result from dilation of the blood vessels underneath the epidermis. There are different inciting events that lead to the 5 different types of angiokeratomas. The overlying epidermal changes are secondary to the underlying process of capillary ectasia.¹ This lesion was not part of a cluster, so it was characterized as a solitary angiokeratoma. Smaller lesions are usually less keratinized and are commonly seen on the scrotum and vulva, where there are usually multiple lesions (referred to as angiokeratoma of Fordyce).

Zaballos² studied the dermoscopic characteristics of 32 solitary angiokeratomas and reported 6 findings in at least half of the solitary lesions. The most common features were dark lacunae in 94% of the lesions, white veil in 91%, and erythema in 69%. Peripheral erythema, red lacunae, and hemorrhagic crusts were all seen at a rate of 53%. The most common location was the lower extremities.

This patient’s previous pathology report from a shave biopsy was found, confirming that the original diagnosis was angiokeratoma. Since the patient’s lesion had not resolved and was symptomatic from minor trauma, he was scheduled to come back in for an elliptical excision to remove the lesion.

CHICAGO – Taking NSAIDs for knee osteoarthritis may worsen inflammation and pain over time, suggest new data revealed at the annual meeting of the Radiological Society of North America.

Johanna Luitjens, MD, a postdoctoral scholar in the department of radiology and biomedical Imaging at the University of California, San Francisco, told this news organization that NSAIDs are frequently used to treat OA pain because inflammation is one of the main drivers of OA, but whether they actually help outcomes has been unclear. Her study suggests that they don’t help – and may actually worsen – outcomes.

Denise Fulton/MDedge News

In particular, this study looked at the impact of NSAIDs on synovitis – the inflammation of the membrane lining the knee joint – by using MRI-based structural biomarkers.

OA, the most common form of arthritis, affects more than 32 million adults in the United States and more than 500 million people worldwide.
 

No approved therapy to reduce OA progression

Little is known of the long-term effects of NSAIDs on OA progression. Currently, there’s no approved therapy to cure OA or to reduce its advance.

Dr. Luitjens noted, however, that the synovial membrane mediates development and progression of OA and may be a good therapeutic target.

Researchers studied participants from the Osteoarthritis Initiative (OAI) cohort with moderate to severe OA who used NSAIDs regularly for at least 1 year between baseline and 4-year follow-up. All participants had high-quality 3T MRI of the knee at baseline and after 4 years. Images were scored for biomarkers of inflammation, including cartilage thickness and composition.

Dr. Luitjens and associates studied 721 participants who matched the inclusion criteria (129 with and 592 participants without regular NSAID use). The available data did not further specify amounts of NSAIDs used.

At baseline, significantly higher signal intensity in the infrapatellar fat pad (IFP) was seen in patients who used NSAID, compared with controls (adjusted difference in score, 0.26; 95% confidence interval, –0.5 to –0.129; P = .039).

In addition, at the end of the study period, there was a significantly greater increase in signal intensity of IFP (adjusted difference in score, 0.46; 95% CI, 0.2-0.72; P < .001) and higher increase in effusion synovitis (adjusted difference in score, 0.27; 95% CI, 0.06-0.47;  P = .01) in NSAID users, compared with controls.

IFP size and synovial proliferation score did not different significantly between groups at the start of the study and showed no significant change over time.

The results showed no long-term benefit of NSAID use. Joint inflammation and cartilage quality were worse at baseline in the participants taking NSAIDs, compared with the control group, and worsened at 4-year follow-up.

Design limits strength

Amanda E. Nelson, MD, associate professor of medicine, division of rheumatology, allergy, and immunology at the University of North Carolina at Chapel Hill, cautioned against assuming causality, pointing out that the OAI is an observational cohort study. (Dr. Nelson was not involved in the OAI or Dr. Luitjens’ analysis.)

“[The OAI is] large and well known, but it wasn’t designed to compare these groups, and this was a small subset,” she said in an interview. Without randomization, it’s hard to judge the results.

“It may be that people on NSAIDs for the duration of the study had more pain and had more disease to begin with, or had more symptoms or had failed other treatments,” she said, adding that the effect sizes were small.

Measures such as the IFP are ranked 0-3, so “the clinical difference of a 0.26 difference on a 0-3 scale is a bit uncertain,” she said.

Dr. Luitjens said that the researchers tried to adjust for potential confounders but agreed that randomized controlled trials are needed to better advise physicians and patients on the benefits or harms of using NSAIDs for OA.

Weighing the risks in older adults

Una Makris, MD, associate professor of internal medicine in the division of rheumatic diseases at the University of Texas Southwestern Medical Center, Dallas, noted that NSAIDs are “not always the safest option.”

“We are still in desperate need of disease-modifying drugs in OA with rigorous randomized trials to show efficacy for outcomes that are most meaningful to patients,” Dr. Makris, who was not involved in the study, told this news organization.

“OA is most common in older adults, those often with multiple comorbidities, so we must always weigh the risks – including known adverse effects which can be amplified in older adults – and benefits with the goal of improved function and less pain,” Dr. Makris said.

NSAID use also should be considered in the context of body mass index, cardiovascular risk, prior trauma or injury, other medication use, and behavioral factors, including physical activity, she said.

Dr. Luitjens, Dr. Nelson, and Dr. Makris reported no relevant financial relationships.

Strength training is the most effective form of exercise for reducing migraine, with high-intensity aerobics coming in second, and both beating top-line migraine medications topiramate and amitriptyline, new research suggests.

The new results should encourage clinicians to recommend patients with migraine engage in strength-training exercise whenever possible, study investigator Yohannes W. Woldeamanuel, MD, a physician-scientist and instructor, department of neurology and neurological sciences, Stanford (Calif.) University, told this news organization.

“Exercise is something patients can do all their lives and use it to prevent migraine attacks instead of taking daily medications or repetitive injections that have several adverse effects.”

The findings were published online in the Journal of Headache and Pain.
 

Head-to-head comparison

Several clinical trials have shown exercise is effective for migraine management, but to date, there have been no head-to-head comparisons of strength training and aerobic exercise, said Dr. Woldeamanuel.

This new study used a systematic review with network meta-analysis (NMA), which compares multiple interventions and ranks the efficacy of each one.

After a literature search, researchers included 21 clinical trials with an exercise regimen arm and a comparison control arm. All study data reported monthly frequency of migraine at baseline and at the end of the intervention.

The total combined sample size was 1,195 patients with migraine, who were a mean age of 35.5 years, with a female-to-male ratio of 6.7:1. All studies used International Classification of Headache Disorders (ICHD) criteria for migraine diagnosis.

The NMA provided 27 pairwise comparisons and 8 indirect comparisons. The pairwise comparisons provided direct evidence between the different interventions.

Researchers combined strength training, including weightlifting, with resistance training. Both modalities target muscles, while aerobic exercise targets cardiovascular health.

The average number of weeks was 9.3, 9.3, and 10.7, and the average number of hours per session for strength/resistance training, high-intensity aerobic exercise, and moderate-intensity aerobic exercise interventions was 50, 56, and 45.3, respectively.

The analysis showed all exercise interventions were more effective than the placebo groups in reducing the frequency of migraine. In terms of ranking, strength training came out on top, with a mean difference in monthly migraine days of −3.55 (95% confidence interval, −6.15 to −0.95) between the active and placebo groups.

Next was high-intensity aerobic exercise (−3.13; 95% CI, −5.28 to −0.97) and moderate-intensity aerobic exercise (−2.18; 95% CI, −3.25 to −1.11), followed by topiramate, placebo, and then amitriptyline.

Strength/resistance training was superior possibly because it targets muscle strengthening, particularly major muscles in the neck and shoulder area, which can be a source of the pain trigger, said Dr. Woldeamanuel. He added neck pain is highly comorbid with migraine.

Interestingly, patients doing exercises that focus on unaffected muscles – for example, squats – still get the benefits of less migraine burden, said Dr. Woldeamanuel.
 

Training recommendations

Strength training also increases or preserves lean muscle mass, which is associated with reduced migraine frequency. Research shows preservation of lean body mass combats central sensitization in various pain syndromes, said Dr. Woldeamanuel.

The superior effects of high- versus moderate-intensity aerobic exercise may be due to recruitment of endogenous molecules involved in exercise-mediated hypoalgesia (pain reduction).

The most common pathways are the opioid and endocannabinoid systems, although other systems are also likely involved, said Dr. Woldeamanuel. He noted migraine has been linked to a deficiency of both opioidergic and endocannabinoidergic signaling.

Dr. Woldeamanuel commented on the difficulty of comparing exercise interventions for patients with chronic versus episodic migraine, as many studies include both.

However, the two studies with moderate-intensity aerobic exercise exclusively involving patients with chronic migraine showed large effect sizes (Cohen’s d) of 0.80 and 1.10 in reducing monthly headache frequency.

Based on these new results and their own experience, the researchers recommend strength training start with 50% of repetition maximum (RM) with 2-3 sets of 12-15 repetitions three times a week along with 10 minutes of warm-up, stretching, and cool-down, totaling 45-60 minutes per session. Weight/resistance load can then be increased weekly by 5% of RM if the patient is capable of successfully completing three sets.

They also recommend including active recovery days (low-intensity exercise) between training days. All major muscles, including neck, shoulder, and upper limb muscles, should be trained in a rotation.

For high-intensity aerobic exercise, the authors recommend starting with interval training at 55% VO_2max (maximum respiratory capacity), or 50% HRmax (maximal heart rate) for 45-60 minutes per session, including 10 minutes of warm-up and cool-down, three times per week. The intensity can then be increased by 5%-10% each week to reach a maximum target of 80%-90% by week 12.

It is best for patients to start with a trainer for guidance and supervision, but once they master the routines, they can do the exercises independently, said Dr. Woldeamanuel.
 

Managing flare-ups

Headache flare-ups are normal during exercise, which may be caused by “boom and bust cycles” – exercising excessively when feeling good then completely stopping when feeling bad, said Dr. Woldeamanuel. He noted these flare-ups don’t mean “there’s something wrong with the brain or there’s some injury to muscles.”

The best way to manage such flare-ups is to use a pacing strategy that involves “not going overboard on good days and avoiding excessive rest on bad days,” the investigators note.

Dr. Woldeamanuel noted exercise is a lifestyle-based intervention; it not only helps reduce migraine attacks but also helps control other known comorbidities such as obesity and hypertension.

In a comment, Elizabeth Loder, MD, vice-chair, academic affairs, department of neurology, Brigham and Women’s Hospital, and professor of neurology, Harvard Medical School, both in Boston, said, “It’s useful to collect and summarize all of these studies, and to focus on helping patients and doctors understand the possible value of different kinds of exercise.”

The review was “well done,” said Dr. Loder, adding the researchers “have looked carefully at the quality of included studies.”

The study received support from the National Institute of Neurological Disorders and Stroke of the National Institutes of Health. Dr. Woldeamanuel has reported no relevant financial relationships.

The new results should encourage clinicians to recommend patients with migraine engage in strength-training exercise whenever possible, study investigator Yohannes W. Woldeamanuel, MD, a physician-scientist and instructor, department of neurology and neurological sciences, Stanford (Calif.) University, told this news organization.

“Exercise is something patients can do all their lives and use it to prevent migraine attacks instead of taking daily medications or repetitive injections that have several adverse effects.”

The findings were published online in the Journal of Headache and Pain.
 

Head-to-head comparison

Several clinical trials have shown exercise is effective for migraine management, but to date, there have been no head-to-head comparisons of strength training and aerobic exercise, said Dr. Woldeamanuel.

This new study used a systematic review with network meta-analysis (NMA), which compares multiple interventions and ranks the efficacy of each one.

After a literature search, researchers included 21 clinical trials with an exercise regimen arm and a comparison control arm. All study data reported monthly frequency of migraine at baseline and at the end of the intervention.

The total combined sample size was 1,195 patients with migraine, who were a mean age of 35.5 years, with a female-to-male ratio of 6.7:1. All studies used International Classification of Headache Disorders (ICHD) criteria for migraine diagnosis.

The NMA provided 27 pairwise comparisons and 8 indirect comparisons. The pairwise comparisons provided direct evidence between the different interventions.

Researchers combined strength training, including weightlifting, with resistance training. Both modalities target muscles, while aerobic exercise targets cardiovascular health.

The average number of weeks was 9.3, 9.3, and 10.7, and the average number of hours per session for strength/resistance training, high-intensity aerobic exercise, and moderate-intensity aerobic exercise interventions was 50, 56, and 45.3, respectively.

The analysis showed all exercise interventions were more effective than the placebo groups in reducing the frequency of migraine. In terms of ranking, strength training came out on top, with a mean difference in monthly migraine days of −3.55 (95% confidence interval, −6.15 to −0.95) between the active and placebo groups.

Next was high-intensity aerobic exercise (−3.13; 95% CI, −5.28 to −0.97) and moderate-intensity aerobic exercise (−2.18; 95% CI, −3.25 to −1.11), followed by topiramate, placebo, and then amitriptyline.

Strength/resistance training was superior possibly because it targets muscle strengthening, particularly major muscles in the neck and shoulder area, which can be a source of the pain trigger, said Dr. Woldeamanuel. He added neck pain is highly comorbid with migraine.

Interestingly, patients doing exercises that focus on unaffected muscles – for example, squats – still get the benefits of less migraine burden, said Dr. Woldeamanuel.
 

Training recommendations

Strength training also increases or preserves lean muscle mass, which is associated with reduced migraine frequency. Research shows preservation of lean body mass combats central sensitization in various pain syndromes, said Dr. Woldeamanuel.

The superior effects of high- versus moderate-intensity aerobic exercise may be due to recruitment of endogenous molecules involved in exercise-mediated hypoalgesia (pain reduction).

The most common pathways are the opioid and endocannabinoid systems, although other systems are also likely involved, said Dr. Woldeamanuel. He noted migraine has been linked to a deficiency of both opioidergic and endocannabinoidergic signaling.

Dr. Woldeamanuel commented on the difficulty of comparing exercise interventions for patients with chronic versus episodic migraine, as many studies include both.

However, the two studies with moderate-intensity aerobic exercise exclusively involving patients with chronic migraine showed large effect sizes (Cohen’s d) of 0.80 and 1.10 in reducing monthly headache frequency.

Based on these new results and their own experience, the researchers recommend strength training start with 50% of repetition maximum (RM) with 2-3 sets of 12-15 repetitions three times a week along with 10 minutes of warm-up, stretching, and cool-down, totaling 45-60 minutes per session. Weight/resistance load can then be increased weekly by 5% of RM if the patient is capable of successfully completing three sets.

They also recommend including active recovery days (low-intensity exercise) between training days. All major muscles, including neck, shoulder, and upper limb muscles, should be trained in a rotation.

For high-intensity aerobic exercise, the authors recommend starting with interval training at 55% VO_2max (maximum respiratory capacity), or 50% HRmax (maximal heart rate) for 45-60 minutes per session, including 10 minutes of warm-up and cool-down, three times per week. The intensity can then be increased by 5%-10% each week to reach a maximum target of 80%-90% by week 12.

It is best for patients to start with a trainer for guidance and supervision, but once they master the routines, they can do the exercises independently, said Dr. Woldeamanuel.
 

Managing flare-ups

Headache flare-ups are normal during exercise, which may be caused by “boom and bust cycles” – exercising excessively when feeling good then completely stopping when feeling bad, said Dr. Woldeamanuel. He noted these flare-ups don’t mean “there’s something wrong with the brain or there’s some injury to muscles.”

The best way to manage such flare-ups is to use a pacing strategy that involves “not going overboard on good days and avoiding excessive rest on bad days,” the investigators note.

Dr. Woldeamanuel noted exercise is a lifestyle-based intervention; it not only helps reduce migraine attacks but also helps control other known comorbidities such as obesity and hypertension.

In a comment, Elizabeth Loder, MD, vice-chair, academic affairs, department of neurology, Brigham and Women’s Hospital, and professor of neurology, Harvard Medical School, both in Boston, said, “It’s useful to collect and summarize all of these studies, and to focus on helping patients and doctors understand the possible value of different kinds of exercise.”

The review was “well done,” said Dr. Loder, adding the researchers “have looked carefully at the quality of included studies.”

The study received support from the National Institute of Neurological Disorders and Stroke of the National Institutes of Health. Dr. Woldeamanuel has reported no relevant financial relationships.

PHILADELPHIA – 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.”

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.

Texas-based researchers have developed a vaccine that blocks the euphoric effects of fentanyl, a potent synthetic opioid that is increasingly involved in opioid overdose deaths in the United States.

In studies in male and female mice, the vaccine generated significant and long-lasting levels of anti-fentanyl antibodies that were highly effective at reducing the antinociceptive, behavioral, and physiological effects of the drug.

The vaccine prevents fentanyl from entering the brain. “Thus, the individual will not feel the euphoric effects and can ‘get back on the wagon’ to sobriety,” lead investigator Colin Haile, MD, PhD, with University of Houston and founding member of the UH Drug Discovery Institute, said in a news release. The study was published online in the journal Pharmaceutics.

“The anti-fentanyl antibodies were specific to fentanyl and a fentanyl derivative and did not cross-react with other opioids, such as morphine. That means a vaccinated person would still be able to be treated for pain relief with other opioids,” said Dr. Haile.

The vaccine did not cause any adverse effects in the immunized mice. The research team plans to start manufacturing clinical-grade vaccine in the coming months with clinical trials in humans planned soon.

If proven safe and effective in clinical testing, the vaccine could have major implications for the nation’s opioid epidemic by becoming a relapse prevention agent for people trying to quit using opioids, the researchers note.

The United States in 2021 recorded more than 107,000 drug overdose deaths – a record high, according to federal health officials – and fentanyl was involved in most of these deaths. 

Senior author Therese Kosten, PhD, director of the UH Developmental, Cognitive & Behavioral Neuroscience program, calls the new fentanyl vaccine a potential “game changer.”

“Fentanyl use and overdose is a particular treatment challenge that is not adequately addressed with current medications because of its pharmacodynamics, and managing acute overdose with the short-acting naloxone [Narcan] is not appropriately effective as multiple doses of naloxone are often needed to reverse fentanyl’s fatal effects,” said Dr. Kosten.

Funding for the study was provided by the Department of Defense through the Alcohol and Substance Abuse Disorders Program managed by RTI International’s Pharmacotherapies for Alcohol and Substance Use Disorders Alliance, which has funded Dr. Haile’s lab for several years to develop the anti-fentanyl vaccine. The authors have no relevant conflicts of interest. A provisional patent has been submitted by the University of Houston on behalf of four of the investigators containing technology related to the fentanyl vaccine.

The vaccine prevents fentanyl from entering the brain. “Thus, the individual will not feel the euphoric effects and can ‘get back on the wagon’ to sobriety,” lead investigator Colin Haile, MD, PhD, with University of Houston and founding member of the UH Drug Discovery Institute, said in a news release. The study was published online in the journal Pharmaceutics.

“The anti-fentanyl antibodies were specific to fentanyl and a fentanyl derivative and did not cross-react with other opioids, such as morphine. That means a vaccinated person would still be able to be treated for pain relief with other opioids,” said Dr. Haile.

The vaccine did not cause any adverse effects in the immunized mice. The research team plans to start manufacturing clinical-grade vaccine in the coming months with clinical trials in humans planned soon.

If proven safe and effective in clinical testing, the vaccine could have major implications for the nation’s opioid epidemic by becoming a relapse prevention agent for people trying to quit using opioids, the researchers note.

The United States in 2021 recorded more than 107,000 drug overdose deaths – a record high, according to federal health officials – and fentanyl was involved in most of these deaths. 

Senior author Therese Kosten, PhD, director of the UH Developmental, Cognitive & Behavioral Neuroscience program, calls the new fentanyl vaccine a potential “game changer.”

“Fentanyl use and overdose is a particular treatment challenge that is not adequately addressed with current medications because of its pharmacodynamics, and managing acute overdose with the short-acting naloxone [Narcan] is not appropriately effective as multiple doses of naloxone are often needed to reverse fentanyl’s fatal effects,” said Dr. Kosten.

Funding for the study was provided by the Department of Defense through the Alcohol and Substance Abuse Disorders Program managed by RTI International’s Pharmacotherapies for Alcohol and Substance Use Disorders Alliance, which has funded Dr. Haile’s lab for several years to develop the anti-fentanyl vaccine. The authors have no relevant conflicts of interest. A provisional patent has been submitted by the University of Houston on behalf of four of the investigators containing technology related to the fentanyl vaccine.

Roughly 7% of all adult Americans may currently have had long COVID, with symptoms that have lasted 3 months or longer, according to the latest U.S. government survey done in October. More than a quarter say their condition is severe enough to significantly limit their day-to-day activities – yet the problem is only barely starting to get the attention of employers, the health care system, and policymakers.

With no cure or treatment in sight, long COVID is already burdening not only the health care system, but also the economy – and that burden is set to grow. Many experts worry about the possible long-term ripple effects, from increased spending on medical care costs to lost wages due to not being able to work, as well as the policy implications that come with addressing these issues.

“At this point, anyone who’s looking at this seriously would say this is a huge deal,” says senior Brookings Institution fellow Katie Bach, the author of a study that analyzed long COVID’s impact on the labor market.

“We need a real concerted focus on treating these people, which means both research and the clinical side, and figuring out how to build a labor market that is more inclusive of people with disabilities,” she said.

It’s not only that many people are affected. It’s that they are often affected for months and possibly even years.

The U.S. government figures suggest more than 18 million people could have symptoms of long COVID right now. The latest Household Pulse Survey by the Census Bureau and the National Center for Health Statistics takes data from 41,415 people.

A preprint of a study by researchers from City University of New York, posted on medRxiv in September and based on a similar population survey done between June 30 and July 2, drew comparable results. The study has not been peer reviewed.

More than 7% of all those who answered said they had long COVID at the time of the survey, which the researchers said corresponded to approximately 18.5 million U.S. adults. The same study found that a quarter of those, or an estimated 4.7 million adults, said their daily activities were impacted “a lot.”

This can translate into pain not only for the patients, but for governments and employers, too.

In high-income countries around the world, government surveys and other studies are shedding light on the extent to which post-COVID-19 symptoms – commonly known as long COVID – are affecting populations. While results vary, they generally fall within similar ranges.

The World Health Organization estimates that between 10% and 20% of those with COVID-19 go on to have an array of medium- to long-term post-COVID-19 symptoms that range from mild to debilitating. The U.S. Government Accountability Office puts that estimate at 10% to 30%; one of the latest studies published at the end of October in The Journal of the American Medical Association found that 15% of U.S. adults who had tested positive for COVID-19 reported current long COVID symptoms. Elsewhere, a study from the Netherlands published in The Lancet in August found that one in eight COVID-19 cases, or 12.7%, were likely to become long COVID.

“It’s very clear that the condition is devastating people’s lives and livelihoods,” WHO Director-General Tedros Adhanom Ghebreyesus wrote in an article for The Guardian newspaper in October.

“The world has already lost a significant number of the workforce to illness, death, fatigue, unplanned retirement due to an increase in long-term disability, which not only impacts the health system, but is a hit to the overarching economy … the impact of long COVID for all countries is very serious and needs immediate and sustained action equivalent to its scale.”
 

Global snapshot: Lasting symptoms, impact on activities

Patients describe a spectrum of persistent issues, with extreme fatigue, brain fog or cognitive problems, and shortness of breath among the most common complaints. Many also have manageable symptoms that worsen significantly after even mild physical or mental exertion.

Women appear almost twice as likely as men to get long COVID. Many patients have other medical conditions and disabilities that make them more vulnerable to the condition. Those who face greater obstacles accessing health care due to discrimination or socioeconomic inequity are at higher risk as well. 

While many are older, a large number are also in their prime working age. The Census Bureau data show that people ages 40-49 are more likely than any other group to get long COVID, which has broader implications for labor markets and the global economy. Already, experts have estimated that long COVID is likely to cost the U.S. trillions of dollars and affect multiple industries.

“Whether they’re in the financial world, the medical system, lawyers, they’re telling me they’re sitting at the computer screen and they’re unable to process the data,” said Zachary Schwartz, MD, medical director for Vancouver General Hospital’s Post-COVID-19 Recovery Clinic.

“That is what’s most distressing for people, in that they’re not working, they’re not making money, and they don’t know when, or if, they’re going to get better.”

Nearly a third of respondents in the Census Bureau’s Household Pulse Survey who said they have had COVID-19 reported symptoms that lasted 3 months or longer. People between the ages of 30 and 59 were the most affected, with about 32% reporting symptoms. Across the entire adult U.S. population, the survey found that 1 in 7 adults have had long COVID at some point during the pandemic, with about 1 in 18 saying it limited their activity to some degree, and 1 in 50 saying they have faced “a lot” of limits on their activities. Any way these numbers are dissected, long COVID has impacted a large swath of the population.

Yet research into the causes and possible treatments of long COVID is just getting underway.

“The amount of energy and time devoted to it is way, way less than it should, given how many people are likely affected,” said David Cutler, PhD, professor of economics at Harvard University, Cambridge, Mass., who has written about the economic cost of long COVID. “We’re way, way underdoing it here. And I think that’s really a terrible thing.”

Population surveys and studies from around the world show that long COVID lives up to its name, with people reporting serious symptoms for months on end.

In October, Statistics Canada and the Public Health Agency of Canada published early results from a questionnaire done between spring and summer 2022 that found just under 15% of adults who had a confirmed or suspected case of COVID-19 went on to have new or continuing symptoms 3 or more months later. Nearly half, or 47.3%, dealt with symptoms that lasted a year or more. More than one in five said their symptoms “often or always” limited their day-to-day activities, which included routine tasks such as preparing meals, doing errands and chores, and basic functions such as personal care and moving around in their homes.

Nearly three-quarters of workers or students said they missed an average of 20 days of work or school. 

“We haven’t yet been able to determine exactly when symptoms resolve,” said Rainu Kaushal, MD, the senior associate dean for clinical research at Weill Cornell Medicine in New York. She is co-leading a national study on long COVID in adults and children, funded by the National Institutes of Health RECOVER Initiative.

“But there does seem to be, for many of the milder symptoms, resolution at about 4-6 weeks. There seems to be a second point of resolution around 6 months for certain symptoms, and then some symptoms do seem to be permanent, and those tend to be patients who have underlying conditions,” she said.
 

Reducing the risk

Given all the data so far, experts recommend urgent policy changes to help people with long COVID.

“The population needs to be prepared, that understanding long COVID is going to be a very long and difficult process,” said Alexander Charney, MD, PhD, associate professor and the lead principal investigator of the RECOVER adult cohort at Icahn School of Medicine at Mount Sinai in New York. He said the government can do a great deal to help, including setting up a network of connected clinics treating long COVID, standardizing best practices, and sharing information.

“That would go a long way towards making sure that every person feels like they’re not too far away from a clinic where they can get treated for this particular condition,” he said.

But the only known way to prevent long COVID is to prevent COVID-19 infections in the first place, experts say. That means equitable access to tests, therapeutics, and vaccines.

“I will say that avoiding COVID remains the best treatment in the arsenal right now,” said Dr. Kaushal. This means masking, avoiding crowded places with poor ventilation and high exposure risk, and being up to date on vaccinations, she said.

A number of papers – including a large U.K. study published in May 2022, another one from July, and the JAMA study from October – all suggest that vaccinations can help reduce the risk of long COVID.

“I am absolutely of the belief that vaccination has reduced the incidence and overall amount of long COVID … [and is] still by far the best thing the public can do,” said Dr. Schwartz.

PHILADELPHIA – For patients with rheumatoid arthritis who are already at increased risk for major adverse cardiovascular events (MACE), NSAIDs may be safer than opioids, results of a new-user active comparator study suggest.

Among 6,866 patients with RA who started on opioids and 13,698 patients who started on NSAIDs for pain, the use of both weak and strong opioids was associated with a 33% increase in risk for all-cause mortality and a trend toward higher rates of venous thromboembolism (VTE), compared with NSAID use, reported Gulsen Ozen, MD, of the University of Nebraska Medical Center, Omaha.

Neil Osterweil/MDedge News

“Pain in RA is a very complex process, and we know that it’s not solely dependent on the disease activity, but there is no evidence that opioids have any benefit in long-term pain management, and it can even cause hyperalgesia. And as we show, it’s not safer than NSAIDs,” she said in an oral abstract session at the annual meeting of the American College of Rheumatology.

She stressed that patients should be assessed for non-RA causes of pain and should use nonpharmacologic methods when possible.

“If a pharmacological treatment is needed and NSAIDs are contraindicated, the lowest possible dose of weak opioids can be used for a very limited time for acute pain only,” she said.
 

Pain despite disease control

Even when their disease is well controlled, approximately 60% of patients with RA still report pain. NSAIDs are commonly used to treat pain in patients with RA, but they are associated with modest increases in risk for cardiovascular disease (CVD), gastrointestinal bleeding, renal injury, and hypertension.

Some providers are leery of NSAIDs and will instead prescribe either regular or intermittent opioids for pain control in their patients.

Disease-modifying antirheumatic drugs have only minimal pain-relieving benefits, “and even worse, opioids can delay initiation of DMARDs in RA,” Dr. Ozen said.

Opioids have been shown to increase oxidative stress, platelet aggregation, and myocardial fibrosis, as well as hypogonadism, weight gain, and CVD risk factors.

There is little evidence, however, on whether opioids are associated with cardiovascular events in patients with RA. This dearth of data prompted Dr. Ozen and colleagues to study the relative risks for MACE in patients with RA starting on opioids or NSAIDs for pain.

Matched cohorts

They used data from FORWARD, a joint Canadian and U.S. databank for rheumatic diseases, to conduct a new-user active comparator cohort study. The cohort included adults with RA without cancer who participated in FORWARD for a minimum of 1 year between 1998 and 2021.

The patients were followed either from drug initiation until 3 months after the end of treatment, defined as either discontinuation or a switch to a different analgesic, end of study follow-up, or the development of a MACE outcome.

The investigators used propensity score matching to compare each opioid initiator with two NSAID initiators. The participants were matched by age, sex, body mass index, smoking, alcohol, RA duration, disease activity, Health Assessment Questionnaire, visual analog scale for pain, joint surgeries, prior CVD and VTE, hypertension, diabetes, rheumatic diseases comorbidity index, osteoporosis/fractures, thyroid, chronic liver, kidney, lung and mental health diseases, hospitalizations, 36-Item Short Form Health Survey scores, and sleep scores.

The two groups were well matched, except for a slightly higher incidence of VTE in opioid initiators, although incidence rates were low in both groups (0.9% vs. 0.6% of NSAID initiators).
 

Higher death rate in opioid users

The incidence rate of MACE among opioid initiators was 20.6% versus18.9% among NSAID initiators, a difference that was not statistically significant. There were also no significant differences in incidence rates of the individual components of the MACE composite outcome: myocardial infarction, stroke, heart failure, CVD death, or VTE.

There were, however, significantly more deaths from any cause among patients in the opioid group, with an incidence rate of 13.5% versus 10.8% in the NSAID group.

An analysis of the associaion of drug type with outcomes, adjusted for propensity score weight and prior VTE showed that patients on opioids had a statistically significant hazard ratio for death from any cause of 1.33 (95% confidence interval, 1.06-1.67).

The increased risk for all-cause mortality occurred both in patients starting on weak opioids (hydrocodone, tramadol, codeine, pentazocine, and propoxyphene) and on strong opioids (hydromorphone, dihydromorphinone, oxymorphone, butorphanol, methadone, morphine, oxycodone, meperidine, and fentanyl).

As noted before, there was a trend toward an increased risk for VTE among opioid initiators, but this was not statistically significant.

The increase in risk was higher among patients on strong versus weak opioids, suggesting a dose-dependent relationship, Dr. Ozen said.

A comparison of opioid-associated risk for all-cause mortality vs. NSAIDs according to type (nonselective or selective) showed that most of the increase in risk was relative to selective cycloxygenase-2 inhibitors.

‘Beautiful’ analysis

“This is a beautiful piece of analysis on a really difficult question to address because the confounding is really hard to unpick,” commented James Galloway, MBBS, deputy head of the center for rheumatic diseases at King’s College London and consulting rheumatologist at King’s College Hospital, also in London.

“The headline message is that there didn’t appear to be a clear signal that NSAIDs were worse, which is what I thought the preexisting view might have been. And so, people may have paradoxically prescribed opioids in favor of NSAIDs in a person with cardiovascular risk,” he said in an interview. Dr. Galloway attended the oral abstract session but was not involved in the study.

The study was supported by a grant to Dr. Ozen from the Rheumatology Research Foundation. Dr. Galloway reported having no relevant disclosures.

PHILADELPHIA – For patients with rheumatoid arthritis who are already at increased risk for major adverse cardiovascular events (MACE), NSAIDs may be safer than opioids, results of a new-user active comparator study suggest.

Among 6,866 patients with RA who started on opioids and 13,698 patients who started on NSAIDs for pain, the use of both weak and strong opioids was associated with a 33% increase in risk for all-cause mortality and a trend toward higher rates of venous thromboembolism (VTE), compared with NSAID use, reported Gulsen Ozen, MD, of the University of Nebraska Medical Center, Omaha.

“Pain in RA is a very complex process, and we know that it’s not solely dependent on the disease activity, but there is no evidence that opioids have any benefit in long-term pain management, and it can even cause hyperalgesia. And as we show, it’s not safer than NSAIDs,” she said in an oral abstract session at the annual meeting of the American College of Rheumatology.

She stressed that patients should be assessed for non-RA causes of pain and should use nonpharmacologic methods when possible.

“If a pharmacological treatment is needed and NSAIDs are contraindicated, the lowest possible dose of weak opioids can be used for a very limited time for acute pain only,” she said.
 

Pain despite disease control

Even when their disease is well controlled, approximately 60% of patients with RA still report pain. NSAIDs are commonly used to treat pain in patients with RA, but they are associated with modest increases in risk for cardiovascular disease (CVD), gastrointestinal bleeding, renal injury, and hypertension.

Some providers are leery of NSAIDs and will instead prescribe either regular or intermittent opioids for pain control in their patients.

Disease-modifying antirheumatic drugs have only minimal pain-relieving benefits, “and even worse, opioids can delay initiation of DMARDs in RA,” Dr. Ozen said.

Opioids have been shown to increase oxidative stress, platelet aggregation, and myocardial fibrosis, as well as hypogonadism, weight gain, and CVD risk factors.

There is little evidence, however, on whether opioids are associated with cardiovascular events in patients with RA. This dearth of data prompted Dr. Ozen and colleagues to study the relative risks for MACE in patients with RA starting on opioids or NSAIDs for pain.

Matched cohorts

They used data from FORWARD, a joint Canadian and U.S. databank for rheumatic diseases, to conduct a new-user active comparator cohort study. The cohort included adults with RA without cancer who participated in FORWARD for a minimum of 1 year between 1998 and 2021.

The patients were followed either from drug initiation until 3 months after the end of treatment, defined as either discontinuation or a switch to a different analgesic, end of study follow-up, or the development of a MACE outcome.
