Rheumatology

The first biosimilar for Humira, adalimumab-atto (Amjevita), is now available in the United States, according to an announcement on Jan. 31 by the manufacturer, Amgen. At least seven other U.S. Food and Drug Administration–approved Humira biosimilars are expected to become available later in 2023.

Amjevita was approved by the FDA in September 2016 for multiple inflammatory diseases, including rheumatoid arthritis, psoriatic arthritis, ankylosing spondylitis, Crohn’s disease, ulcerative colitis, and plaque psoriasis. The delayed launch was part of a global settlement with Humira’s manufacturer, AbbVie.

Humira (adalimumab) has been available since 2002 and is consistently one of the top-selling drugs in the United States. A single 40-mg Amjevita pen device will be available at two prices: a list price (wholesale acquisition cost) of $1,557.59, 55% below the current Humira list price, and a list price of $3,288.24, 5% below the current Humira list price, according to Amgen.

“Amgen’s goal is to provide broad access for patients by offering two options to health plans and pharmacy benefit managers,” the company said in the press release.

Patients are less likely to benefit from the more significant discount, said Marta Wosinska, PhD, a health care economist at the Brookings Institute in Washington, DC. It's expected that insurance companies will use the higher list price for Amjevita, she said, as this higher price will also likely have higher rebates. Rebates are payments to health insurance payers provided by drug manufacturers to promote use of an expensive drug. Some pharmacy benefit managers have already said that they plan to charge patients the same amount for Humira as its biosimilars, Dr. Wosinska said.

"For an existing patient, there's really no incentive for them to switch," she said in an interview.

So far only one insurance company, Kaiser Permanente, has plans to switch patients over to biosimilars, according to the health policy podcast Tradeoffs, and the insurer will stop covering Humira by the end of this year.

If you could go back in time 75 years and tell Dr. Sidney Farber, the developer of methotrexate for cancer therapy, that 21st-century medicine would utilize his specially designed drug more in rheumatology than oncology, he might be surprised. He might scratch his head even more, hearing of his drug sparking interest in still other medical fields, like cardiology.

But drug repurposing is not so uncommon. One classic example is aspirin. Once the most common pain medication and used also in rheumatology, aspirin now finds a range of applications, from colorectal cancer to the prevention of cardiovascular and cerebrovascular thrombosis. Minoxidil is another example, developed for hypertension but used today mostly to stop hair loss. Perhaps most ironic is thalidomide, utilized today for leprosy and multiple myeloma, yet actually contraindicated for its original application, nausea of pregnancy.

Methotrexate, thus, has much in common with other medical treatments, and yet its origin story is as unique and as fascinating as the story of Dr. Farber himself. While this is a rheumatology article, it’s also a story about the origin of a particular rheumatologic treatment, and so the story of that origin will take us mostly through a discussion of hematologic malignancy and of the clinical researcher who dared search for a cure.

Born in 1903, in Buffalo, New York, third of fourteen children of Jewish immigrants from Poland, Dr. Farber grew up in a household that was crowded but academically rigorous. His father, Simon, routinely brought home textbooks, assigning each child a book to read and on which to write a report. His mother, Matilda, was as devoted as her husband to raising the children to succeed in their adopted new country. Upstairs, the children were permitted to speak Yiddish, but downstairs they were required to use only English and German.

As a teen, Dr. Farber lived through the 1918 influenza pandemic that killed at least 50 million people worldwide, including more than 2,000 Buffalonians. This probably helped motivate him to study medicine, but with antisemitism overt in the America of the early 1920s, securing admission to a U.S. medical school was close to impossible. So, in what now seems like the greatest of ironies, Dr. Farber began medical studies in Germany, then transferred for the second year to a U.S. program that seemed adequate – Harvard Medical School, from which he graduated in 1927. From there, he trained as a pathologist, focusing ultimately on pediatric pathology. But, frustrated by case after case of malignancy, whose young victims he’d often have to autopsy, Dr. Farber decided that he wanted to advance the pitiful state of cancer therapeutics, especially for hematologic malignancy.

This was a tall order in the 1930s and early 1940s, when cancer therapeutics consisted only of surgical resection and very primitive forms of radiation therapy. Applicable only to neoplasia that was localized, these options were useless against malignancies in the blood, like acute lymphoblastic leukemia (ALL), but by January 1948 there was at least one glimmer of hope. At that time, one patient with ALL, 2-year-old Robert Sandler, was too ill to join his twin brother Elliott for snow play outside their home in the Dorchester section of Boston. Diagnosed back in August, Robert had suffered multiple episodes of fever, anemia, and thrombocytopenia. His illness had enlarged his spleen dramatically and caused pathologic bone fractures with excruciating bone pain, and for a while he couldn’t walk because of pressure on his lower spinal cord. All of this was the result of uncontrolled mitosis and cell division of lymphoblasts, immature lymphocytes. By December, these out-of-control cells had elevated the boy’s white blood cell count to a peak of 70,000/mcL, more than six times the high end of the normal range (4,500-11,000/mcL). This had happened despite treatment with an experimental drug, developed at Boston Children’s Hospital by Dr. Farber and his team, working on the assumption that inhibition of folate metabolism should slow the growth of tumor cells. On Dec. 28, however, Dr. Farber had switched the child to a new drug with a chemical structure just slightly different from the other agent’s.

Merely another chemical modification in a series of attempts by the research team, the new drug, aminopterin, was not expected to do anything dramatic, but Dr. Farber and the team had come such a long way since the middle of 1947, when he’d actually done the opposite of what he was doing now. On the basis of British research from India showing folic acid deficiency as the basis of a common type of anemia in malnourished people, Dr. Farber had reasoned that children with leukemia, who also suffered from anemia, might also benefit from folic acid supplementation. Even without prior rodent testing, Dr. Farber had tried giving the nutrient to patients with ALL, a strategy made possible by the presence of a spectacular chemist working on folic acid synthesis at Farber’s own hospital to help combat folate deficiency. Born into a poor Brahmin family in India, the chemist, Dr. Yellapragada SubbaRow, had begun life with so much stacked against him as to appear even less likely during childhood than the young Dr. Farber to grow up to make major contributions to medicine. Going through childhood with death all around him, Dr. SubbaRow was motivated to study medicine, but getting into medical school had been an uphill fight, given his family’s economic difficulty. Knowing that he’d also face discrimination on account of his low status after receiving admission to a medical program, SubbaRow could have made things a bit easier for himself by living within the norms of the British Imperial system, but as a supporter of Mohandas Gandhi’s nationalist movement, he boycotted British goods. As a medical student, this meant doing things like wearing Indian-made surgical gloves, instead of the English products that were expected of the students. Such actions led Dr. SubbaRow to receive a kind of second-rate medical degree, rather than the prestigious MBBS.

The political situation also led Dr. SubbaRow to emigrate to the United States, where, ironically, his medical degree initially was taken less seriously than it had been taken in his British-occupied homeland. He thus worked in the capacity of a hospital night porter at Peter Bent Brigham Hospital (the future Brigham and Women’s Hospital), doing menial tasks like changing sheets to make ends meet. He studied, however, and made enough of an impression to gain admission to the same institution that also admitted Farber through the backdoor, Harvard Medical School. This launched him into a research career in which he not only would be instrumental in developing folate antagonists and other classes of drugs, but also would make him the codiscoverer of the role of creatine phosphate and ATP in cellular energy metabolism. Sadly, even after obtaining his top-notch American credentials and contributing through his research to what you might say is a good chunk of the biochemistry pathways that first year medical students memorize without ever learning who discovered them, Dr. SubbaRow still faced prejudice for the rest of his life, which turned out to last only until the age of 53. To add insult to injury, he is rarely remembered for his role.

Dr. Farber proceeded with the folic acid supplementation idea in patients with ALL, even though ALL caused a hypoproliferative anemia, whereas anemia from folate deficiency was megaloblastic, meaning that erythrocytes were produced but they were oversized and dysfunctional. Tragically, folic acid had accelerated the disease process in children with ALL, but the process of chemical experimentation aimed at synthesizing folate also produced some compounds that mimicked chemical precursors of folate in a way that made them antifolates, inhibitors of folate metabolism. If folic acid made lymphoblasts grow faster, Dr. Farber had reasoned that antifolates should inhibit their growth. He thus asked the chemistry lab to focus on folate inhibitors. Testing aminopterin, beginning with young Robert Sandler at the end of December, is what proved his hypothesis correct. By late January, aminopterin had brought the child’s WBC count down to the realm of 12,000, just slightly above normal, with symptoms and signs abating as well, and by February, the child could play with his twin brother. It was not a cure; malignant lymphoblasts still showed on microscopy of Robert’s blood. While he and some 15 other children whom Dr. Farber treated in this early trial would all succumb to ALL, they experienced remission lasting several months.

This was a big deal because the concept of chemotherapy was based only on serendipitous observations of WBC counts dropping in soldiers exposed to nitrogen mustard gas during World War I and during an incident in World War II, yet aminopterin had been designed from the ground up. Though difficult to synthesize in quantities, there was no reason for Dr. Farber’s team not to keep tweaking the drug, and so they did. Replacing one hydrogen atom with a methyl group, they turned it into methotrexate.

Proving easier to synthesize and less toxic, methotrexate would become a workhorse for chemotherapy over the next couple of decades, but the capability of both methotrexate and aminopterin to blunt the growth of white blood cells and other cells did not go unnoticed outside the realm of oncology. As early as the 1950s, dermatologists were using aminopterin to treat psoriasis. This led to the approval of methotrexate for psoriasis in 1972.

Meanwhile, like oncology, infectious diseases, aviation medicine, and so many other areas of practice, rheumatology had gotten a major boost from research stemming from World War II. During the war, Dr. Philip Hench of the Mayo Clinic developed cortisone, which pilots used to stay alert and energetic during trans-Atlantic flights. But it turned out that cortisone had a powerful immunosuppressive effect that dramatically improved rheumatoid arthritis, leading Dr. Hench to receive the Nobel Prize in Physiology or Medicine in 1950. By the end of the 1950s, however, the significant side effects of long-term corticosteroid therapy were very clear, so over the next few decades there was a major effort to develop different treatments for RA and other rheumatologic diseases.

Top on the list of such agents was methotrexate, developed for RA in part by Dr. Michael Weinblatt of Brigham and Women’s Hospital in Boston. In the 1980s, Dr. Weinblatt published the first clinical trial showing the benefits of methotrexate for RA patients. This has since developed into a standard treatment, noticeably different from the original malignancy application in that it is a low-dose regimen. Patients taking methotrexate for RA typically receive no more than 25 mg per week orally, and often much less. Rheumatology today includes expertise in keeping long-term methotrexate therapy safe by monitoring liver function and through other routine tests. The routine nature of the therapy has brought methotrexate to the point of beckoning in a realm that Dr. Farber might not have predicted in his wildest imagination: cardiology. This is on account of the growing appreciation of the inflammatory process in the pathophysiology of atherosclerotic heart disease.

Meanwhile, being an antimetabolite, harmful to rapidly dividing cells, the danger of methotrexate to the embryo and fetus was recognized early. This made methotrexate off-limits to pregnant women, yet it also has made the drug useful as an abortifacient. Though not as good for medication abortion in unwanted but thriving pregnancies, where mifepristone/misoprostol has become the regimen of choice, methotrexate has become a workhorse in other obstetrical settings, such as for ending ectopic pregnancy.

Looking at the present and into the future, the potential for this very old medication looks wide open, as if it could go in any direction, so let’s wind up the discussion with the thought that we may be in for some surprises. Rather than jumping deeply into any rheumatologic issue, we spent most of this article weaving through other medical issues, but does this not make today’s story fairly analogous to rheumatology itself?

Dr. Warmflash is a physician from Portland, Ore. He reported no conflicts of interest.

Merely another chemical modification in a series of attempts by the research team, the new drug, aminopterin, was not expected to do anything dramatic, but Dr. Farber and the team had come such a long way since the middle of 1947, when he’d actually done the opposite of what he was doing now. On the basis of British research from India showing folic acid deficiency as the basis of a common type of anemia in malnourished people, Dr. Farber had reasoned that children with leukemia, who also suffered from anemia, might also benefit from folic acid supplementation. Even without prior rodent testing, Dr. Farber had tried giving the nutrient to patients with ALL, a strategy made possible by the presence of a spectacular chemist working on folic acid synthesis at Farber’s own hospital to help combat folate deficiency. Born into a poor Brahmin family in India, the chemist, Dr. Yellapragada SubbaRow, had begun life with so much stacked against him as to appear even less likely during childhood than the young Dr. Farber to grow up to make major contributions to medicine. Going through childhood with death all around him, Dr. SubbaRow was motivated to study medicine, but getting into medical school had been an uphill fight, given his family’s economic difficulty. Knowing that he’d also face discrimination on account of his low status after receiving admission to a medical program, SubbaRow could have made things a bit easier for himself by living within the norms of the British Imperial system, but as a supporter of Mohandas Gandhi’s nationalist movement, he boycotted British goods. As a medical student, this meant doing things like wearing Indian-made surgical gloves, instead of the English products that were expected of the students. Such actions led Dr. SubbaRow to receive a kind of second-rate medical degree, rather than the prestigious MBBS.

The political situation also led Dr. SubbaRow to emigrate to the United States, where, ironically, his medical degree initially was taken less seriously than it had been taken in his British-occupied homeland. He thus worked in the capacity of a hospital night porter at Peter Bent Brigham Hospital (the future Brigham and Women’s Hospital), doing menial tasks like changing sheets to make ends meet. He studied, however, and made enough of an impression to gain admission to the same institution that also admitted Farber through the backdoor, Harvard Medical School. This launched him into a research career in which he not only would be instrumental in developing folate antagonists and other classes of drugs, but also would make him the codiscoverer of the role of creatine phosphate and ATP in cellular energy metabolism. Sadly, even after obtaining his top-notch American credentials and contributing through his research to what you might say is a good chunk of the biochemistry pathways that first year medical students memorize without ever learning who discovered them, Dr. SubbaRow still faced prejudice for the rest of his life, which turned out to last only until the age of 53. To add insult to injury, he is rarely remembered for his role.

Dr. Farber proceeded with the folic acid supplementation idea in patients with ALL, even though ALL caused a hypoproliferative anemia, whereas anemia from folate deficiency was megaloblastic, meaning that erythrocytes were produced but they were oversized and dysfunctional. Tragically, folic acid had accelerated the disease process in children with ALL, but the process of chemical experimentation aimed at synthesizing folate also produced some compounds that mimicked chemical precursors of folate in a way that made them antifolates, inhibitors of folate metabolism. If folic acid made lymphoblasts grow faster, Dr. Farber had reasoned that antifolates should inhibit their growth. He thus asked the chemistry lab to focus on folate inhibitors. Testing aminopterin, beginning with young Robert Sandler at the end of December, is what proved his hypothesis correct. By late January, aminopterin had brought the child’s WBC count down to the realm of 12,000, just slightly above normal, with symptoms and signs abating as well, and by February, the child could play with his twin brother. It was not a cure; malignant lymphoblasts still showed on microscopy of Robert’s blood. While he and some 15 other children whom Dr. Farber treated in this early trial would all succumb to ALL, they experienced remission lasting several months.

This was a big deal because the concept of chemotherapy was based only on serendipitous observations of WBC counts dropping in soldiers exposed to nitrogen mustard gas during World War I and during an incident in World War II, yet aminopterin had been designed from the ground up. Though difficult to synthesize in quantities, there was no reason for Dr. Farber’s team not to keep tweaking the drug, and so they did. Replacing one hydrogen atom with a methyl group, they turned it into methotrexate.

Proving easier to synthesize and less toxic, methotrexate would become a workhorse for chemotherapy over the next couple of decades, but the capability of both methotrexate and aminopterin to blunt the growth of white blood cells and other cells did not go unnoticed outside the realm of oncology. As early as the 1950s, dermatologists were using aminopterin to treat psoriasis. This led to the approval of methotrexate for psoriasis in 1972.

Meanwhile, like oncology, infectious diseases, aviation medicine, and so many other areas of practice, rheumatology had gotten a major boost from research stemming from World War II. During the war, Dr. Philip Hench of the Mayo Clinic developed cortisone, which pilots used to stay alert and energetic during trans-Atlantic flights. But it turned out that cortisone had a powerful immunosuppressive effect that dramatically improved rheumatoid arthritis, leading Dr. Hench to receive the Nobel Prize in Physiology or Medicine in 1950. By the end of the 1950s, however, the significant side effects of long-term corticosteroid therapy were very clear, so over the next few decades there was a major effort to develop different treatments for RA and other rheumatologic diseases.

Top on the list of such agents was methotrexate, developed for RA in part by Dr. Michael Weinblatt of Brigham and Women’s Hospital in Boston. In the 1980s, Dr. Weinblatt published the first clinical trial showing the benefits of methotrexate for RA patients. This has since developed into a standard treatment, noticeably different from the original malignancy application in that it is a low-dose regimen. Patients taking methotrexate for RA typically receive no more than 25 mg per week orally, and often much less. Rheumatology today includes expertise in keeping long-term methotrexate therapy safe by monitoring liver function and through other routine tests. The routine nature of the therapy has brought methotrexate to the point of beckoning in a realm that Dr. Farber might not have predicted in his wildest imagination: cardiology. This is on account of the growing appreciation of the inflammatory process in the pathophysiology of atherosclerotic heart disease.

Meanwhile, being an antimetabolite, harmful to rapidly dividing cells, the danger of methotrexate to the embryo and fetus was recognized early. This made methotrexate off-limits to pregnant women, yet it also has made the drug useful as an abortifacient. Though not as good for medication abortion in unwanted but thriving pregnancies, where mifepristone/misoprostol has become the regimen of choice, methotrexate has become a workhorse in other obstetrical settings, such as for ending ectopic pregnancy.

Looking at the present and into the future, the potential for this very old medication looks wide open, as if it could go in any direction, so let’s wind up the discussion with the thought that we may be in for some surprises. Rather than jumping deeply into any rheumatologic issue, we spent most of this article weaving through other medical issues, but does this not make today’s story fairly analogous to rheumatology itself?

Dr. Warmflash is a physician from Portland, Ore. He reported no conflicts of interest.

High levels of high-density lipoprotein cholesterol (HDL-C) in older adults are associated with a higher risk of sustaining a fracture than lower HDL-C levels, a new study suggests.

“Two animal studies showing that HDL-C reduces bone mineral density by reducing osteoblast number and function provide a plausible explanation for why high HDL-C may increase the risk of fractures,” Monira Hussain, MBBS, MPH, PhD, of Monash University in Melbourne, told this news organization. “So, it was not surprising when our analyses provided evidence that amongst those in the highest quintile of HDL-C (> 74 mg/dL), there was a [33%] increased risk of fractures.”

After adjustment, one standard deviation increment in HDL-C level was associated with a 14% higher risk of fracture during a 4-year follow-up.

Based on this and other studies, Dr. Hussain said, “I believe that the finding of a very high HDL-C [should] alert clinicians to a higher risk of mortality, fractures, and possibly other threats to their patient’s health.”

The study was published online in JAMA Cardiology.
 

Independent risk factor

For this report, the researchers conducted a post hoc analysis of data from the Aspirin in Reducing Events in the Elderly (ASPREE) clinical trial and the ASPREE-Fracture substudy.

ASPREE was a double-blind, randomized, placebo-controlled primary prevention trial of aspirin. Participants were 16,703 community-dwelling Australians and 2,411 individuals from the United States with a mean age of 75 and without evident cardiovascular disease, dementia, physical disability, or life-limiting chronic illness.

The ASPREE-Fracture substudy collected data on fractures reported post randomization from the Australian participants. Fractures were confirmed by imaging and adjudicated by an expert panel and included both traumatic and minimal trauma fractures.

Of the 16,262 participants who had a plasma HDL-C measurement at baseline (55% women), 1,659 (10.2%) experienced at least one fracture over a median of 4 years. This included 711 minimal trauma fractures (for example, falls from standing height) and 948 other trauma fractures, mainly falls on stairs, ladders, or stools.

Higher rates of fractures occurred in the highest quintile of HDL-C level where the mean level was 89 mg/dL. At baseline, participants in that quintile had a lower BMI, a high prevalence of current/former smoking and current alcohol use, 12 years or longer of school, more physical activity, and higher use of antiosteoporosis medication. They also had less chronic kidney disease, diabetes, prefrailty/frailty, or treatment with lipid-lowering drugs.

In a fully adjusted model, each standard deviation increment in HDL-C level was associated with a 14% higher risk of fractures (hazard ratio, 1.14). When analyzed in quintiles, compared with participants in Q1, those in Q5 had a 33% higher risk for fracture (HR, 1.33).

Prevalence rates were similar between the sexes. The increase in fracture risk appeared to be independent of traditional risk factors for fractures, including age, sex, physical activity, alcohol use, frailty, BMI, smoking status, diabetes, chronic kidney disease, use of lipid-lowering or antiosteoporosis drugs, and education, the authors note.

The results persisted in sensitivity analyses in restricted subgroups of interest and in stratified analyses – including, for example, only minimal fractures; participants not taking antiosteoporosis drugs or statins; never smokers; nondrinkers; and those engaging in minimal physical activity (walking less than 30 minutes per day).

No association was observed between non–HDL-C levels and fractures.

The authors conclude that the study “provides robust evidence that higher levels of HDL-C are associated with incident fractures in both male and female individuals, independent of conventional risk factors.”
 

Clinically useful?

Commenting on the study for this news organization, Marilyn Tan, MD, clinic chief of the Endocrine Clinic and clinical associate professor of medicine at Stanford (Calif.) University, said, “I certainly would not recommend anyone do anything to actively lower their HDL levels. HDL levels are largely determined by genetics, diet, and lifestyle, with some effects from certain medications/supplements. Studies have demonstrated that moderately higher HDL levels may be protective for atherosclerosis.”

In the current study, she said, “Causation has not been proven, and importantly there is no evidence that reducing HDL levels reduces fracture risk. Also, this association between raised HDL levels and fracture risk has not been demonstrated consistently in other studies.”

Furthermore, she noted, the preclinical trials on which the authors based their hypothesis – that is, an association between HDL and a reduction in the number and function of osteoblasts – “has not been demonstrated widely in human subjects.”

“We have a large armamentarium of FDA-approved treatments for osteoporosis that have been clinically proven to reduce fracture risk very significantly, and these are the tools [in addition to lifestyle changes] we should use to reduce fracture risk,” Dr. Tan concluded.

John Wilkins, MD, of Northwestern University, Chicago, and Anand Rohatgi, MD, MSCS, of UT Southwestern Medical Center, Dallas, also point out some limitations of the study in a related editorial.

They note the inclusion of predominantly healthy adults with a mean age of 75, a population that could yield different findings from middle-aged cohorts with chronic illnesses, as well as a lack of clarity regarding the possible role of alcohol intake among the study participants.

Furthermore, the editorialists write, although significant associations were shown in this study, “models were not adjusted for detailed measures of exercise/activity, triglycerides, or any other lipids, including other HDL compositional measures such as HDL-P or ApoA-I levels. There was no assessment of whether HDL-C improved discrimination, reclassification, or any other validated measures of risk prediction performance.

“Taken together,” they conclude, “this study alone leaves several unanswered questions as to whether high HDL-C could be a useful biomarker to detect fracture risk.”

No commercial funding was disclosed. The authors report no relevant financial relationships.

A recently discovered inflammatory disease known as VEXAS syndrome is more common, variable, and dangerous than previously understood, according to results of a retrospective observational study of a large health care system database. The findings, published in JAMA, found that it struck 1 in 4,269 men over the age of 50 in a largely White population and caused a wide variety of symptoms.

“The disease is quite severe,” study lead author David Beck, MD, PhD, of the department of medicine at NYU Langone Health, said in an interview. Patients with the condition “have a variety of clinical symptoms affecting different parts of the body and are being managed by different medical specialties.”

Dr. Beck and colleagues first described VEXAS (vacuoles, E1-ubiquitin-activating enzyme, X-linked, autoinflammatory, somatic) syndrome in 2020. They linked it to mutations in the UBA1 (ubiquitin-like modifier activating enzyme 1) gene. The enzyme initiates a process that identifies misfolded proteins as targets for degradation.

“VEXAS syndrome is characterized by anemia and inflammation in the skin, lungs, cartilage, and joints,” Dr. Beck said. “These symptoms are frequently mistaken for other rheumatic or hematologic diseases. However, this syndrome has a different cause, is treated differently, requires additional monitoring, and can be far more severe.”

According to him, hundreds of people have been diagnosed with the disease in the short time since it was defined. The disease is believed to be fatal in some cases. A previous report found that the median survival was 9 years among patients with a certain variant; that was significantly less than patients with two other variants.

For the new study, researchers searched for UBA1 variants in genetic data from 163,096 subjects (mean age, 52.8 years; 94% White, 61% women) who took part in the Geisinger MyCode Community Health Initiative. The 1996-2022 data comes from patients at 10 Pennsylvania hospitals.

Eleven people (9 males, 2 females) had likely UBA1 variants, and all had anemia. The cases accounted for 1 in 13,591 unrelated people (95% confidence interval, 1:7,775-1:23,758), 1 in 4,269 men older than 50 years (95% CI, 1:2,319-1:7,859), and 1 in 26,238 women older than 50 years (95% CI, 1:7,196-1:147,669).

Other common findings included macrocytosis (91%), skin problems (73%), and pulmonary disease (91%). Ten patients (91%) required transfusions.

Five of the 11 subjects didn’t meet the previously defined criteria for VEXAS syndrome. None had been diagnosed with the condition, which is not surprising considering that it hadn’t been discovered and described until recently.

Just over half of the patients – 55% – had a clinical diagnosis that was previously linked to VEXAS syndrome. “This means that slightly less than half of the patients with VEXAS syndrome had no clear associated clinical diagnosis,” Dr. Beck said. “The lack of associated clinical diagnoses may be due to the variety of nonspecific clinical characteristics that span different subspecialities in VEXAS syndrome. VEXAS syndrome represents an example of a multisystem disease where patients and their symptoms may get lost in the shuffle.”

In the future, “professionals should look out for patients with unexplained inflammation – and some combination of hematologic, rheumatologic, pulmonary, and dermatologic clinical manifestations – that either don’t carry a clinical diagnosis or don’t respond to first-line therapies,” Dr. Beck said. “These patients will also frequently be anemic, have low platelet counts, elevated markers of inflammation in the blood, and be dependent on corticosteroids.”

Diagnosis can be made via genetic testing, but the study authors note that it “is not routinely offered on standard workup for myeloid neoplasms or immune dysregulation diagnostic panels.”

As for treatment, Dr. Beck said the disease “can be partially controlled by multiple different anticytokine therapies or biologics. However, in most cases, patients still need additional steroids and/or disease-modifying antirheumatic agents [DMARDs]. In addition, bone marrow transplantation has shown signs of being a highly effective therapy.”

The study authors say more research is needed to understand the disease’s prevalence in more diverse populations.

In an interview, Matthew J. Koster, MD, a rheumatologist at Mayo Clinic in Rochester, Minn., who’s studied the disease but didn’t take part in this research project, said the findings are valid and “highly important.

“The findings of this study highlight what many academic and quaternary referral centers were wondering: Is VEXAS really more common than we think, with patients hiding in plain sight? The answer is yes,” he said. “Currently, there are less than 400 cases reported in the literature of VEXAS, but large centers are diagnosing this condition with some frequency. For example, at Mayo Clinic in Rochester, we diagnose on average one new patient with VEXAS every 7-14 days and have diagnosed 60 in the past 18 months. A national collaborative group in France has diagnosed approximately 250 patients over that same time frame when pooling patients nationwide.”

The prevalence is high enough, he said, that “clinicians should consider that some of the patients with diseases that are not responding to treatment may in fact have VEXAS rather than ‘refractory’ relapsing polychondritis or ‘recalcitrant’ rheumatoid arthritis, etc.”

The National Institute of Health funded the study. Dr. Beck, the other authors, and Dr. Koster report no disclosures.

In the future, “professionals should look out for patients with unexplained inflammation – and some combination of hematologic, rheumatologic, pulmonary, and dermatologic clinical manifestations – that either don’t carry a clinical diagnosis or don’t respond to first-line therapies,” Dr. Beck said. “These patients will also frequently be anemic, have low platelet counts, elevated markers of inflammation in the blood, and be dependent on corticosteroids.”

Diagnosis can be made via genetic testing, but the study authors note that it “is not routinely offered on standard workup for myeloid neoplasms or immune dysregulation diagnostic panels.”

As for treatment, Dr. Beck said the disease “can be partially controlled by multiple different anticytokine therapies or biologics. However, in most cases, patients still need additional steroids and/or disease-modifying antirheumatic agents [DMARDs]. In addition, bone marrow transplantation has shown signs of being a highly effective therapy.”

The study authors say more research is needed to understand the disease’s prevalence in more diverse populations.

In an interview, Matthew J. Koster, MD, a rheumatologist at Mayo Clinic in Rochester, Minn., who’s studied the disease but didn’t take part in this research project, said the findings are valid and “highly important.

“The findings of this study highlight what many academic and quaternary referral centers were wondering: Is VEXAS really more common than we think, with patients hiding in plain sight? The answer is yes,” he said. “Currently, there are less than 400 cases reported in the literature of VEXAS, but large centers are diagnosing this condition with some frequency. For example, at Mayo Clinic in Rochester, we diagnose on average one new patient with VEXAS every 7-14 days and have diagnosed 60 in the past 18 months. A national collaborative group in France has diagnosed approximately 250 patients over that same time frame when pooling patients nationwide.”

The prevalence is high enough, he said, that “clinicians should consider that some of the patients with diseases that are not responding to treatment may in fact have VEXAS rather than ‘refractory’ relapsing polychondritis or ‘recalcitrant’ rheumatoid arthritis, etc.”

The National Institute of Health funded the study. Dr. Beck, the other authors, and Dr. Koster report no disclosures.

A recently discovered inflammatory disease known as VEXAS syndrome is more common, variable, and dangerous than previously understood, according to results of a retrospective observational study of a large health care system database. The findings, published in JAMA, found that it struck 1 in 4,269 men over the age of 50 in a largely White population and caused a wide variety of symptoms.

“The disease is quite severe,” study lead author David Beck, MD, PhD, of the department of medicine at NYU Langone Health, said in an interview. Patients with the condition “have a variety of clinical symptoms affecting different parts of the body and are being managed by different medical specialties.”

Dr. Beck and colleagues first described VEXAS (vacuoles, E1-ubiquitin-activating enzyme, X-linked, autoinflammatory, somatic) syndrome in 2020. They linked it to mutations in the UBA1 (ubiquitin-like modifier activating enzyme 1) gene. The enzyme initiates a process that identifies misfolded proteins as targets for degradation.

“VEXAS syndrome is characterized by anemia and inflammation in the skin, lungs, cartilage, and joints,” Dr. Beck said. “These symptoms are frequently mistaken for other rheumatic or hematologic diseases. However, this syndrome has a different cause, is treated differently, requires additional monitoring, and can be far more severe.”

According to him, hundreds of people have been diagnosed with the disease in the short time since it was defined. The disease is believed to be fatal in some cases. A previous report found that the median survival was 9 years among patients with a certain variant; that was significantly less than patients with two other variants.

For the new study, researchers searched for UBA1 variants in genetic data from 163,096 subjects (mean age, 52.8 years; 94% White, 61% women) who took part in the Geisinger MyCode Community Health Initiative. The 1996-2022 data comes from patients at 10 Pennsylvania hospitals.

Eleven people (9 males, 2 females) had likely UBA1 variants, and all had anemia. The cases accounted for 1 in 13,591 unrelated people (95% confidence interval, 1:7,775-1:23,758), 1 in 4,269 men older than 50 years (95% CI, 1:2,319-1:7,859), and 1 in 26,238 women older than 50 years (95% CI, 1:7,196-1:147,669).

Other common findings included macrocytosis (91%), skin problems (73%), and pulmonary disease (91%). Ten patients (91%) required transfusions.

Five of the 11 subjects didn’t meet the previously defined criteria for VEXAS syndrome. None had been diagnosed with the condition, which is not surprising considering that it hadn’t been discovered and described until recently.

Just over half of the patients – 55% – had a clinical diagnosis that was previously linked to VEXAS syndrome. “This means that slightly less than half of the patients with VEXAS syndrome had no clear associated clinical diagnosis,” Dr. Beck said. “The lack of associated clinical diagnoses may be due to the variety of nonspecific clinical characteristics that span different subspecialities in VEXAS syndrome.

Exercise helps patients with knee osteoarthritis, but more isn’t necessarily better, new research shows.

A low-dose exercise regimen helped patients with knee OA about as much as a more intense workout plan, according to trial results published online in Annals of Internal Medicine.

Both high and low doses of exercise reduced pain and improved function and quality of life.

The improvements with the lower-dose plan and its 98% adherence rate are encouraging, said Nick Trasolini, MD, assistant professor of orthopedic surgery at Atrium Health Wake Forest Baptist Medical Center, Winston-Salem, N.C.

“This is a very doable amount of medical exercise therapy for patients with knee osteoarthritis, and one that makes a big difference in patient-reported symptoms,” Dr. Trasolini, who was not involved in the study, said in an interview.
 

What’s the right dose?

Exercise is a go-to treatment for knee OA, but the precise dose to recommend has been unclear. To study this question, Tom Arild Torstensen, MSc, RPT, with Karolinska Institutet, Huddinge, Sweden, and Holten Institute, Stockholm, and colleagues conducted a trial at four centers in Sweden and Norway.

The study included 189 men and women with knee OA. Participants were randomly assigned to low- or high-dose exercise plans, which they performed three times per week for 12 weeks under the supervision of a physiotherapist.

Participants in the high-dose group performed 11 exercises during each session, which lasted 70-90 minutes.

The low-dose regimen consisted of five exercises – cycling, squats, step-ups, step-downs, and knee extensions – performed for 20–30 minutes.

The researchers measured outcomes using the Knee Injury and Osteoarthritis Outcome Score, which assesses pain, other symptoms, function in daily living, function in sports and recreation, and knee-related quality of life.

“Patients in both groups improved significantly over time, but high-dose exercise was not superior to low-dose exercise in most comparisons,” the study investigators reported

High-dose exercise was associated with better function in sports and recreational activity and knee-related quality of life at 6 months. Those differences did not persist at 1 year, however. The researchers reported no safety concerns with either intervention.

Adherence was “nearly perfect” in the low-dose group. It was slightly lower in the high-dose group, the researchers said.

“Interestingly, it seems that high-dose treatment could be preferable to low-dose treatment in the long run for people who lead active lives,” they wrote. “This should be the subject of future studies.”

All clinical practice guidelines for knee OA recommend exercise, but “we do not know the optimal dose,” Kim Bennell, PhD, a research physiotherapist at the University of Melbourne, said in an interview.

Dose has components, including number of times per week, number of exercises, sets and repetitions, intensity, and duration of exercise sessions, Dr. Bennell said.

“These results suggest that an exercise program that involves less time and fewer exercises can still offer benefits and may be easier for patients to undertake and stick at than one that involves greater time and effort,” she said.

The study was supported by the Swedish Rheumatic Fund. Dr. Trasolini and Dr. Bennell have disclosed no relevant financial relationships.

Helen Tanner remembers stealing glimpses of her husband, Philip (“Phil”) Robinson, MBChB, PhD, associate professor at the University of Queensland (Australia), catching and rehoming huge Huntsman spiders. Robinson made the extra effort because he didn’t want to hurt them; he wasn’t a big fan of the large spider with a potential leg span of 6 inches that’s commonly found in Australia, per the Australian Museum.

Robinson also relished taking his children, Eddie, 4, and Tommy, 7, on roller coaster rides, which they enjoyed, despite the experience typically giving him motion sickness, Tanner said.

“He would do anything to make the children happy,” she said. “His children meant the world to him.”

Robinson died Jan. 3 as a result of diffuse gastric adenocarcinoma, according to his wife, who added that it was a short, 2-week-long illness.
 

A leader of global effort to understand COVID-19 and rheumatic disease

Jinoos Yazdany, MD, MPH, chief of the division of rheumatology at Zuckerberg San Francisco General Hospital and professor of medicine at the University of California, San Francisco, described Robinson as “one of the hardest-working people I have ever known. ... [still] his deep love and dedication for his family and kids was always present.”

Robinson would wake up early, even on weekends, to lead international calls across multiple time zones, Yazdany said. “He was driven by a deep curiosity and an intense desire to generate scholarship that would help people with rheumatic diseases.”

Yazdany added that Robinson had a full research portfolio in gout and spondyloarthritis and a busy clinical practice.

She often caught glimpses of Robinson’s young children during Zoom calls. “He was also a talented baker and loved to bake with his kids, often posting pictures of his creations on social media,” Yazdany said.

A mutual colleague compiled some of Robinson’s baking successes. That includes “ ‘probably about to be locked down’ cookies” on July 17, 2021, and “Queensland lockdown cookies!!!” on July 2, 2021. Reuters reported on July 21, 2021, that Australia was witnessing an alarming increase in COVID-19 cases.

Robinson also worked his social media skills to rally support for the COVID-19 Global Rheumatology Alliance, according to an article published by his colleagues in The Rheumatologist. Yazdany collaborated with him in this effort.

Launched on March 12, 2020, the Global Rheumatology Alliance’s mission is to “collect, analyze, and disseminate information about COVID-19 and rheumatology to patients, physicians, and other relevant groups to improve the care of patients with rheumatic disease.” Robinson served as chair of governance and policy for the collaborative effort.

Inspired by a conversation on Twitter by Leonard Calabrese, DO, a rheumatologist at the Cleveland Clinic in Ohio, about an outcomes registry created by gastroenterologists specific to patients with inflammatory bowel disease, Robinson launched a discussion about a similar effort for rheumatology on Twitter, they write.

Along with colleagues and within a single Zoom conference call, Yazdany and Robinson had a plan to organize the registry, Robinson’s colleagues write.

Two projects of the Global Rheumatology Alliance are a health care provider–entered registry for providers to enter data about rheumatology patients with COVID-19 infections, and their COVID-19 Vax Survey, which is available in 12 languages, including English.

Yazdany had never met Robinson before she started working with him on the Global Rheumatology Alliance. They started chatting on Twitter, then moved to Zoom conference calls, and subsequently had weeks when they talked by phone and “emailed constantly,” she said.

“As I reflect on our initial interactions, I am struck by how brilliantly we got along and trusted each other,” Yazdany told this news organization. “We both liked to think big, believed in inclusive collaborations, and were committed to helping people with rheumatic diseases during a scary and uncertain time.”

Still, Yazdany noted that she and Phil brought different strengths to their collaborations. She brought her skills related to the technical aspects of research databases, while “Phil worked his magic in mobilizing friends and colleagues from all over the world,” she said. “He served as a wonderful leader, one whom people believed in and would follow.”

The two colleagues, who spent much of their collaborations over Zoom calls, email, and Slack, while living more than 7,000 miles apart, finally met in person at ACR Convergence 2022, which took place in Philadelphia that year. “It felt like the best kind of reunion with a dear friend,” Yazdany remembered.
 

A mentor who created a platform for ‘good people to do great things’

David Liew, MBBS, PhD, consultant rheumatologist and clinical pharmacologist at Austin Health in Melbourne, marveled at Robinson’s ability to “distill things simply and cleanly, with clarity but without losing detail.” Liew, who collaborated with Robinson throughout the COVID-19 pandemic, likens the experience to “jamming with [jazz musician John] Coltrane.”

“What I think was particularly remarkable was the capacity to not only have those thoughts himself, but to facilitate others to have that springboard,” said Liew, who added that Robinson “took enormous pleasure in facilitating others’ success.”

“I think the greatest joy he drew out of the COVID-19 Global Rheumatology Alliance, apart from facing up to the challenge that needed to be faced, was creating a platform for good people to do great things,” said Liew, who recalled one situation where Robinson gently challenged him. Looking back now, Liew can “now see he very clearly was laying me up, giving me the best chance to shine.”

He describes Robinson as “a deep soul who loved his wife and two sons enormously” and “a whiskey aficionado.” “[Whiskey] suited his contemplative style,” Liew recalled. “Some of my fondest conversations with him were over a whiskey, either in person or virtually, pondering the ‘big issues.’”
 

A ‘friend and a colleague and so much more’

Claire Barrett, MBBS, president of the Australian Rheumatology Association, described Robinson as a “friend and a colleague and so much more. ... [He was] someone who I worked, laughed, ate, drank, danced, and had fun with,” she told this news organization. They served together as volunteers for the Australian Rheumatology Association and its Queensland branch, as well as Arthritis Queensland; they were also colleagues at Metro North Hospital and Health Service in Brisbane, Queensland.

Robinson was her “go to” for insightful comment on a variety of topics, she said. That could be advice on managing a patient with difficult gout, challenging spondyloarthritis, or the best treatment for a patient with COVID-19.

“[Phil] was a friend I could ask about anything, knowing I would not be judged,” Barrett said. “His kids and our grandkids are similar ages, so we would swap stories and photos and laugh about how cute/funny/cuddly/busy/etc. they were. My heart is broken he won’t get the chance to enjoy their future and the excitement of having Phil continuing to be such an active dad.”

Tanner, Robinson’s wife, said, “he loved everything.” That included the academic side of medicine, and working out what was wrong with his patients and helping them get better. “He was dedicated to this,” she added.

“He also loved the camaraderie of the job – all the people he met and interacted with. [Phil] loved sharing his ideas for research and also discussing complex patients with colleagues. He was driven by finding the answers to problems and doing this as part of a team of researchers/clinicians. He wasn’t interested in personal success.”

Robinson received his medical degree from Otago Medical School in Dunedin, New Zealand, according to the University of Queensland. His specialty training in general and acute care medicine and rheumatology was completed in Wellington, New Zealand, and Dunedin. Robinson also achieved a PhD in human genetics at the University of Queensland Diamantina Institute and had a postdoctoral fellowship at the Queensland Brain Institute at the University of Queensland.

Before his death, he worked at the Royal Brisbane and Women’s Hospital in Herston, Queensland, and at St. Andrew’s War Memorial Hospital in Spring Hill in Brisbane.

Jinoos Yazdany, MD, MPH, chief of the division of rheumatology at Zuckerberg San Francisco General Hospital and professor of medicine at the University of California, San Francisco, described Robinson as “one of the hardest-working people I have ever known. ... [still] his deep love and dedication for his family and kids was always present.”

Robinson would wake up early, even on weekends, to lead international calls across multiple time zones, Yazdany said. “He was driven by a deep curiosity and an intense desire to generate scholarship that would help people with rheumatic diseases.”

Yazdany added that Robinson had a full research portfolio in gout and spondyloarthritis and a busy clinical practice.

She often caught glimpses of Robinson’s young children during Zoom calls. “He was also a talented baker and loved to bake with his kids, often posting pictures of his creations on social media,” Yazdany said.

A mutual colleague compiled some of Robinson’s baking successes. That includes “ ‘probably about to be locked down’ cookies” on July 17, 2021, and “Queensland lockdown cookies!!!” on July 2, 2021. Reuters reported on July 21, 2021, that Australia was witnessing an alarming increase in COVID-19 cases.

Robinson also worked his social media skills to rally support for the COVID-19 Global Rheumatology Alliance, according to an article published by his colleagues in The Rheumatologist. Yazdany collaborated with him in this effort.

Launched on March 12, 2020, the Global Rheumatology Alliance’s mission is to “collect, analyze, and disseminate information about COVID-19 and rheumatology to patients, physicians, and other relevant groups to improve the care of patients with rheumatic disease.” Robinson served as chair of governance and policy for the collaborative effort.

Inspired by a conversation on Twitter by Leonard Calabrese, DO, a rheumatologist at the Cleveland Clinic in Ohio, about an outcomes registry created by gastroenterologists specific to patients with inflammatory bowel disease, Robinson launched a discussion about a similar effort for rheumatology on Twitter, they write.

Along with colleagues and within a single Zoom conference call, Yazdany and Robinson had a plan to organize the registry, Robinson’s colleagues write.

Two projects of the Global Rheumatology Alliance are a health care provider–entered registry for providers to enter data about rheumatology patients with COVID-19 infections, and their COVID-19 Vax Survey, which is available in 12 languages, including English.

Yazdany had never met Robinson before she started working with him on the Global Rheumatology Alliance. They started chatting on Twitter, then moved to Zoom conference calls, and subsequently had weeks when they talked by phone and “emailed constantly,” she said.

“As I reflect on our initial interactions, I am struck by how brilliantly we got along and trusted each other,” Yazdany told this news organization. “We both liked to think big, believed in inclusive collaborations, and were committed to helping people with rheumatic diseases during a scary and uncertain time.”

Still, Yazdany noted that she and Phil brought different strengths to their collaborations. She brought her skills related to the technical aspects of research databases, while “Phil worked his magic in mobilizing friends and colleagues from all over the world,” she said. “He served as a wonderful leader, one whom people believed in and would follow.”

The two colleagues, who spent much of their collaborations over Zoom calls, email, and Slack, while living more than 7,000 miles apart, finally met in person at ACR Convergence 2022, which took place in Philadelphia that year. “It felt like the best kind of reunion with a dear friend,” Yazdany remembered.
 

A mentor who created a platform for ‘good people to do great things’

David Liew, MBBS, PhD, consultant rheumatologist and clinical pharmacologist at Austin Health in Melbourne, marveled at Robinson’s ability to “distill things simply and cleanly, with clarity but without losing detail.” Liew, who collaborated with Robinson throughout the COVID-19 pandemic, likens the experience to “jamming with [jazz musician John] Coltrane.”

“What I think was particularly remarkable was the capacity to not only have those thoughts himself, but to facilitate others to have that springboard,” said Liew, who added that Robinson “took enormous pleasure in facilitating others’ success.”

“I think the greatest joy he drew out of the COVID-19 Global Rheumatology Alliance, apart from facing up to the challenge that needed to be faced, was creating a platform for good people to do great things,” said Liew, who recalled one situation where Robinson gently challenged him. Looking back now, Liew can “now see he very clearly was laying me up, giving me the best chance to shine.”

He describes Robinson as “a deep soul who loved his wife and two sons enormously” and “a whiskey aficionado.” “[Whiskey] suited his contemplative style,” Liew recalled. “Some of my fondest conversations with him were over a whiskey, either in person or virtually, pondering the ‘big issues.’”
 

A ‘friend and a colleague and so much more’

Claire Barrett, MBBS, president of the Australian Rheumatology Association, described Robinson as a “friend and a colleague and so much more. ... [He was] someone who I worked, laughed, ate, drank, danced, and had fun with,” she told this news organization. They served together as volunteers for the Australian Rheumatology Association and its Queensland branch, as well as Arthritis Queensland; they were also colleagues at Metro North Hospital and Health Service in Brisbane, Queensland.

Robinson was her “go to” for insightful comment on a variety of topics, she said. That could be advice on managing a patient with difficult gout, challenging spondyloarthritis, or the best treatment for a patient with COVID-19.

“[Phil] was a friend I could ask about anything, knowing I would not be judged,” Barrett said. “His kids and our grandkids are similar ages, so we would swap stories and photos and laugh about how cute/funny/cuddly/busy/etc. they were. My heart is broken he won’t get the chance to enjoy their future and the excitement of having Phil continuing to be such an active dad.”

Tanner, Robinson’s wife, said, “he loved everything.” That included the academic side of medicine, and working out what was wrong with his patients and helping them get better. “He was dedicated to this,” she added.

“He also loved the camaraderie of the job – all the people he met and interacted with. [Phil] loved sharing his ideas for research and also discussing complex patients with colleagues. He was driven by finding the answers to problems and doing this as part of a team of researchers/clinicians. He wasn’t interested in personal success.”

Robinson received his medical degree from Otago Medical School in Dunedin, New Zealand, according to the University of Queensland. His specialty training in general and acute care medicine and rheumatology was completed in Wellington, New Zealand, and Dunedin. Robinson also achieved a PhD in human genetics at the University of Queensland Diamantina Institute and had a postdoctoral fellowship at the Queensland Brain Institute at the University of Queensland.

Before his death, he worked at the Royal Brisbane and Women’s Hospital in Herston, Queensland, and at St. Andrew’s War Memorial Hospital in Spring Hill in Brisbane.

A new study likely makes the best estimate yet of the degree of retinopathy risk that patients who take the antimalarial drug hydroxychloroquine (HCQ) can expect, deriving mainly from the cumulative dose taken during the first 5 years of use, according to a study published in Annals of Internal Medicine.

HCQ works to decrease activity in a patient’s immune system, which is effective in many cases of systemic lupus erythematosus, one of the most common indications for the drug. However, an adverse outcome of treatment can be HCQ retinopathy, a progressive form of vision loss in patients taking HCQ over an extended period (mostly for longer than 5 years). The disease is often asymptomatic, although some patients do present a paracentral scotoma and a decrease in color vision. Patients may also notice flashing shapes in their vision and find that they have difficulty reading. Eventually, HCQ retinopathy can lead to loss of visual acuity, loss of peripheral vision, and loss of night vision.

Researchers from Kaiser Permanente Northern California and Harvard Medical School analyzed 3,325 persons who received HCQ for 5 or more years between 2004 and 2020. Their goal was to both characterize the long-term risk for incident HCQ retinopathy and examine the degree to which average HCQ dose within the first 5 years of treatment serves as a prediction of the risk.

The researchers then estimated the risk for developing retinopathy after 15 years, according to patients’ average dosing levels during the first 5 years of therapy. Overall, 81 participants developed HCQ retinopathy with overall cumulative incidences of 2.5% after 10 years and 8.6% after 15 years; the risk was greater for those given a higher dose during the first 5 years of treatment.

The mechanism of how HCQ toxicity may occur is still not completely known. There is evidence that toxicity happens because HCQ binds to melanin in both the retinal pigment epithelium and uvea in high concentrations. HCQ can interfere with lysosomal function, leading to oxidation and accumulation of lysosomes, which can cause dysfunction of the retinal pigment epithelium.

Progressive retinopathy can continue even after the drug is stopped. “It’s thought to be a very mild but important risk,” said Nilanjana Bose, MD, MBA, a rheumatologist with Memorial Hermann Health System in Houston. “Patients taking HCQ must be screened for retinal issues, most certainly elderly patients and patients with any kind of comorbidities.”

“Examination alone is not sufficient to evaluate early changes, and specialized testing must be done. These include color photos, visual field tests, optical coherence tomography, fundus autofluorescence and in some cases, multifocal electroretinogram. Also, the AAO [American Academy of Ophthalmology] has specific recommendations related to Asian patients as they may have a different pattern of retinopathy that must also be considered.”
 

More accurate risk measurements

This news organization asked study coauthor April Jorge, MD, assistant professor of medicine in the division of rheumatology, allergy, and immunology at Massachusetts General Hospital and Harvard Medical School, Boston, to discuss the study, how it correlates to past research, and what it adds that’s new and useful to rheumatologists and ophthalmologists:

Question: Your research found that a higher dose of HCQ in the first 5 years of treatment led to a greater risk of retinopathy. Is there any indication that a lower dose given more frequently, either within that 5-year period or longer, would pose a similar risk?

Answer: In our study, we assessed the HCQ dose in the first 5 years of use but followed patients who continued the medication longer than 5 years, through up to 15 years of use. Therefore, we compared the risk of HCQ retinopathy associated with different HCQ dosages but for the same duration of use. We found that for any dose of HCQ, the risk of retinopathy increases the longer the medication is used. However, patients who used a higher dose of HCQ had a higher risk of developing retinopathy over time.

Also unique to our study, we graded the severity of HCQ retinopathy outcomes. This was important, as we found that the majority of retinopathy cases detected through routine screening are mild and presumed to be asymptomatic. This will likely be reassuring news for patients that we can screen for this adverse event to detect it early and prevent vision loss.

Another important difference was that we assessed the risk of retinopathy associated with using over 6 mg/kg per day, between 5 and 6 mg/kg per day, and less than 5 mg/kg per day, whereas the highest dosing group assessed in the 2014 study included all patients using over 5 mg/kg per day. The risk was considerably higher in the > 6 mg/kg per day group than in the 5-6 mg/kg per day group.

Q: How can rheumatologists and ophthalmologists use this new information specifically to better treat their patients?

A: Our study provides more accurate estimates of the risk of HCQ retinopathy than in prior studies. These risk estimates can be used when rheumatologists (and other clinicians who prescribe HCQ) consider the risks and benefits of this otherwise important and well-tolerated medication. The risk associated with different dose ranges could also inform dosing decisions, since dosing over 6 mg/kg per day may be more of a concern than using doses in the 5-6 mg/kg range. Ophthalmologists can also use these new risk estimates to counsel patients of the importance of HCQ retinopathy screening and can also hopefully provide some reassurance to patients that the risk of severe retinopathy is low as long as they are being monitored.

The study authors were supported by grants from the National Institute of Arthritis and Musculoskeletal and Skin Diseases and the Rheumatology Research Foundation. The authors report no relevant financial relationships. Dr. Bose and Dr. Mirza had no relevant disclosures.

The largest combined analysis of birth outcome data for women with systemic lupus erythematosus (SLE) who took belimumab (Benlysta) during pregnancy appears to indicate that the biologic is “unlikely to cause very frequent birth defects,” but the full extent of possible risk remains unknown. The drug’s effect on B cells, immune function, and infections in exposed offspring were not captured in the data, but a separate case report published after the belimumab pregnancy data report indicates that the drug does cross the placenta and builds up in the blood of the newborn, reducing B cells at birth.

Children of women with SLE have increased birth defect risks, and standard SLE therapeutic agents (for example, cyclophosphamide, methotrexate, mycophenolate mofetil) have been implicated in birth defects and pregnancy loss, but birth defect data for biologic drugs such as belimumab are limited. While belimumab animal data revealed no evidence of fetal harm or pregnancy loss rates, there was evidence of immature and mature B-cell count reductions.

Belimumab is approved by the Food and Drug Administration for use in patients aged 5 years and older with active, autoantibody-positive SLE who are taking standard therapy, and also for those with lupus nephritis.

Michelle Petri, MD, of Johns Hopkins University, Baltimore, and coauthors reported in Annals of the Rheumatic Diseases on data they compiled through March 8, 2020, from belimumab clinical trials, the Belimumab Pregnancy Registry (BPR), and postmarketing/spontaneous reports that encompassed 319 pregnancies with known outcomes.

Across 18 clinical trials with 223 live births, birth defects occurred in 4 of 72 (5.6%) belimumab-exposed pregnancies and in 0 of 9 in placebo-exposed pregnancies. Pregnancy loss (excluding elective terminations) occurred in 31.8% (35 of 110) of belimumab-exposed women and 43.8% (7 of 16) of placebo-exposed women in clinical trials. In the BPR retrospective cohort, 4.2% had pregnancy loss. Postmarketing and spontaneous reports had a pregnancy loss rate of 31.4% (43 of 137). Concomitant medications, confounding factors, and/or missing data were noted in all belimumab-exposed women in clinical trials and the BPR cohort. Dr. Petri and colleagues reported no consistent pattern of birth defects across datasets but stated: “Low numbers of exposed pregnancies, presence of confounding factors/other biases, and incomplete information preclude informed recommendations regarding risk of birth defects and pregnancy loss with belimumab use.”

In an interview, coauthor Megan E. B. Clowse, MD, MPH, associate professor of medicine and director of the division of rheumatology and immunology at Duke University, Durham, N.C., said that “the Annals of the Rheumatic Diseases article provides some reassurance that belimumab is unlikely to cause very frequent birth defects. It is clearly not in the risk-range for thalidomide or mycophenolate. However, due to the complexity of collecting these data, this manuscript can’t explore the full extent of possible risks. It also did not provide information about B cells, immune function, or infection risks in exposed offspring.”

A separate case report by Helle Bitter of the department of rheumatology at Sorlandet Hospital Kristiansand (Norway) in Annals of the Rheumatic Diseases is the first to show transplacental passage of belimumab in humans. Other prior reports have shown such transplacental passage for monoclonal IgG antibodies (tumor necrosis factor inhibitors and rituximab). Even though the last infusion was given late in the second trimester, belimumab was present in cord serum at birth, suggesting much higher concentrations before treatment was stopped. While B-cell numbers were reduced at birth, they returned to normal ranges by 4 months post partum when they were undetectable. In the mother, B-cell numbers remained low throughout the study period extending to 7 months after delivery. The authors stated that the child had a normal vaccination response, and except for the reduced B-cell levels at birth, had no adverse effects of prenatal exposure to maternal medication through age 6 years.

“The belimumab transfer in the case report is the level that we would anticipate based on similar studies in infant/mother pairs on other IgG1 antibody biologics like adalimumab – about 60% higher than the maternal level at birth,” Dr. Clowse said. “That the baby has very low B cells at birth is worrisome to me, demonstrating the lasting effect of maternal belimumab on the infant’s immune system, even when the drug was stopped 14 weeks prior to delivery. While this single infant did not have problems with infections, with more widespread use it seems possible that infants would be found to have higher rates of infections after in utero belimumab exposure.”

The field of lupus research greatly needs controlled studies of newer biologics in pregnancy, Dr. Clowse said. “Women with active lupus in pregnancy – particularly with active lupus nephritis – continue to suffer tragic outcomes at an alarming rate. Newer treatments for lupus nephritis provide some hope that we might be able to control lupus nephritis in pregnancy more effectively. The available data suggests the risks of these medications are not so large as to make studies unreasonable. Our current data doesn’t allow us to sufficiently balance the potential risks and benefits in a way that provides clinically useful guidance. Trials of these medications, however, would enable us to identify improved treatment strategies that could result in healthier women, pregnancies, and babies.”

GlaxoSmithKline funded the study. Dr. Clowse reported receiving consulting fees and grants from UCB and GlaxoSmithKline that relate to pregnancy in women with lupus.

Trials of these medications, however, would enable us to identify improved treatment strategies that could result in healthier women, pregnancies, and babies.”

GlaxoSmithKline funded the study. Dr. Clowse reported receiving consulting fees and grants from UCB and GlaxoSmithKline that relate to pregnancy in women with lupus.

The largest combined analysis of birth outcome data for women with systemic lupus erythematosus (SLE) who took belimumab (Benlysta) during pregnancy appears to indicate that the biologic is “unlikely to cause very frequent birth defects,” but the full extent of possible risk remains unknown. The drug’s effect on B cells, immune function, and infections in exposed offspring were not captured in the data, but a separate case report published after the belimumab pregnancy data report indicates that the drug does cross the placenta and builds up in the blood of the newborn, reducing B cells at birth.

Children of women with SLE have increased birth defect risks, and standard SLE therapeutic agents (for example, cyclophosphamide, methotrexate, mycophenolate mofetil) have been implicated in birth defects and pregnancy loss, but birth defect data for biologic drugs such as belimumab are limited. While belimumab animal data revealed no evidence of fetal harm or pregnancy loss rates, there was evidence of immature and mature B-cell count reductions.

Belimumab is approved by the Food and Drug Administration for use in patients aged 5 years and older with active, autoantibody-positive SLE who are taking standard therapy, and also for those with lupus nephritis.

Michelle Petri, MD, of Johns Hopkins University, Baltimore, and coauthors reported in Annals of the Rheumatic Diseases on data they compiled through March 8, 2020, from belimumab clinical trials, the Belimumab Pregnancy Registry (BPR), and postmarketing/spontaneous reports that encompassed 319 pregnancies with known outcomes.

Across 18 clinical trials with 223 live births, birth defects occurred in 4 of 72 (5.6%) belimumab-exposed pregnancies and in 0 of 9 in placebo-exposed pregnancies. Pregnancy loss (excluding elective terminations) occurred in 31.8% (35 of 110) of belimumab-exposed women and 43.8% (7 of 16) of placebo-exposed women in clinical trials. In the BPR retrospective cohort, 4.2% had pregnancy loss. Postmarketing and spontaneous reports had a pregnancy loss rate of 31.4% (43 of 137). Concomitant medications, confounding factors, and/or missing data were noted in all belimumab-exposed women in clinical trials and the BPR cohort. Dr. Petri and colleagues reported no consistent pattern of birth defects across datasets but stated: “Low numbers of exposed pregnancies, presence of confounding factors/other biases, and incomplete information preclude informed recommendations regarding risk of birth defects and pregnancy loss with belimumab use.”

In an interview, coauthor Megan E. B. Clowse, MD, MPH, associate professor of medicine and director of the division of rheumatology and immunology at Duke University, Durham, N.C., said that “the Annals of the Rheumatic Diseases article provides some reassurance that belimumab is unlikely to cause very frequent birth defects. It is clearly not in the risk-range for thalidomide or mycophenolate. However, due to the complexity of collecting these data, this manuscript can’t explore the full extent of possible risks. It also did not provide information about B cells, immune function, or infection risks in exposed offspring.”

A separate case report by Helle Bitter of the department of rheumatology at Sorlandet Hospital Kristiansand (Norway) in Annals of the Rheumatic Diseases is the first to show transplacental passage of belimumab in humans. Other prior reports have shown such transplacental passage for monoclonal IgG antibodies (tumor necrosis factor inhibitors and rituximab). Even though the last infusion was given late in the second trimester, belimumab was present in cord serum at birth, suggesting much higher concentrations before treatment was stopped. While B-cell numbers were reduced at birth, they returned to normal ranges by 4 months post partum when they were undetectable. In the mother, B-cell numbers remained low throughout the study period extending to 7 months after delivery. The authors stated that the child had a normal vaccination response, and except for the reduced B-cell levels at birth, had no adverse effects of prenatal exposure to maternal medication through age 6 years.

“The belimumab transfer in the case report is the level that we would anticipate based on similar studies in infant/mother pairs on other IgG1 antibody biologics like adalimumab – about 60% higher than the maternal level at birth,” Dr. Clowse said. “That the baby has very low B cells at birth is worrisome to me, demonstrating the lasting effect of maternal belimumab on the infant’s immune system, even when the drug was stopped 14 weeks prior to delivery. While this single infant did not have problems with infections, with more widespread use it seems possible that infants would be found to have higher rates of infections after in utero belimumab exposure.”

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.

“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.

“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.

A re-evaluation of cardiovascular risk management guidelines intended for use by rheumatologists may be warranted based on findings from a recently published population-based study of the risks for 12 different cardiovascular disease outcomes in patients with autoimmune diseases.

“The notion that patients with rheumatic diseases are at increased risk of developing cardiovascular diseases has been ongoing for many years,” Nathalie Conrad, PhD, and coauthors wrote in a viewpoint article in Annals of the Rheumatic Diseases.

This has “sparked much debate concerning whether and when to initiate cardiovascular prevention therapies,” they said.

Dr. Conrad was first author on the population-based study published in The Lancet in August 2022 that used linked primary and secondary care records from datasets in the U.K. Clinical Practice Research Datalink involving individuals who were recently diagnosed with any of 19 different autoimmune diseases during an 18-year period stretching from 2000 to 2017 but free of cardiovascular disease until at least 12 months after incident autoimmune disease. “Every single autoimmune disorder we looked at was associated with increased cardiovascular risk,” Dr. Conrad, of the department of public health and primary care at Catholic University Leuven (Belgium), said in an interview.

Not only was the risk for cardiovascular disease increased for people with rheumatic diseases by an average of 68%, compared with people without rheumatic diseases, but also the whole spectrum of cardiovascular disorders was seen.

“We saw increases in thromboembolic diseases, degenerative heart diseases, and heart inflammation,” Dr. Conrad said.
 

Large datasets examined

The idea for the epidemiologic study came from mounting evidence for cardiovascular disease risk among people with autoimmune diseases but not enough to support the design of specific prevention measures.

Dr. Conrad’s Lancet study examined electronic health records of 446,449 individuals with autoimmune diseases and matched them to 2,102,830 individuals without autoimmune disease. This included 160,217 individuals with seven rheumatic diseases: rheumatoid arthritis, polymyalgia rheumatica, vasculitis, systemic lupus erythematosus, Sjögren’s syndrome, ankylosing spondylitis, and systemic sclerosis.

In addition to looking for any evidence of cardiovascular disease, Dr. Conrad and coauthors looked at 12 specific outcomes: atherosclerotic diseases, peripheral arterial disease, stroke or transient ischemic attack, heart failure, valve disorders, thromboembolic disease, atrial fibrillation or flutter, conduction system disease, supraventricular arrhythmias, aortic aneurysm, myocarditis and pericarditis, and infective endocarditis.
 

CV risk in rheumatic diseases

As might be expected, “greater magnitudes of risk” were seen for individuals with systemic lupus erythematosus and systemic sclerosis than for people in the general population, with the chances of cardiovascular disease being two to four times higher. But what perhaps wasn’t expected was that all rheumatic diseases carried an increased risk for heart or vascular-related problems.

Furthermore, the increased risk could not solely be accounted for by the presence of traditional risk factors, such as blood pressure, smoking, or obesity.

“The background here is that any context of systemic inflammation would be predicted to lead to an increased vascular risk,” Iain McInnes, MD, PhD, professor of medicine and rheumatology at the University of Glasgow, said in an interview. Dr. McInnes was a coauthor of the viewpoint article in Annals of the Rheumatic Diseases.

“The implication is that there may well be increased vascular risk across the whole range of immune-mediated inflammatory diseases,” he added. “We should not, however, infer the magnitude of risk will be the same for each disease.”

What is more intriguing, Dr. McInnes said, is that “we don’t know yet whether there’s one final common pathway that leads to the blood vessel being damaged or whether different diseases might contribute different pathways.”

He added: “A question for the future is to see what are those mechanisms that drive risk across different diseases? And the reason that matters, of course, is that we might want to think about the effectiveness of different therapeutic interventions.”
 

Determining cardiovascular risk

Dr. Conrad and associates in their viewpoint article suggested that an update to the European Alliance of Associations for Rheumatology guidelines for cardiovascular risk management of rheumatic and musculoskeletal diseases (RMDs) could tailor cardiovascular risk scores to certain diseases.

They suggested that the guidelines could consider a risk multiplier of 2.5 for systemic sclerosis, 2.0 for lupus, and 1.5 for any other rheumatic disease.

“We argue that [EULAR] recommendations should consider this new evidence of poorer cardiovascular health in numerous RMDs and envisage cardiovascular screening and associated prevention measures,” Dr. Conrad said.

While they recognize that risk multipliers aren’t perfect, “they are the best available option until personalized risk prediction tools are developed specifically for patients with RMDs.”
 

Addressing cardiovascular risk

As a former president of EULAR, Dr. McInnes was keen to point out that “EULAR’s recommendations are evidence based and are rigorously built on [standard operating procedures] that work and have stood the test of time. I’m quite sure that the members of relevant EULAR task forces will be looking at these data, but they’ll be looking at the whole range of literature to see whether change is necessary.”

Good-quality inflammatory disease control will certainly contribute to reducing vascular risk, “but we should not make the assumption that it will be sufficient,” he cautioned. “We still have to be very careful in addressing so called conventional risk factors, but in particular thinking about obesity and cardiometabolic syndrome to be sure that when those are present, that we detect them and we treat them appropriately.”

As to who is best placed to manage a patient’s cardiovascular risk profile, Dr. McInnes said: “I think the rheumatologist has a responsibility to make sure that as much of the patient’s disease spectrum is being treated as possible.”

“As a rheumatologist, I would like to know that those elements of a patient’s disease presentation are being addressed,” whether that is by a primary care physician, cardiologist, diabetologist, or other specialist involved in the optimal management of the patient.

Dr. Conrad acknowledged receiving support from the European Union’s Horizon 2020 Program, the European Society for Cardiology, and grant funding paid to her institution from the Belgian-based Research Foundation Flounders. She also acknowledged receipt of royalties in regard to the intellectual property of a home-monitoring system for heart failure paid to Oxford University Innovation. Dr. McInnes acknowledged financial relationships with many pharmaceutical companies.

As a former president of EULAR, Dr. McInnes was keen to point out that “EULAR’s recommendations are evidence based and are rigorously built on [standard operating procedures] that work and have stood the test of time. I’m quite sure that the members of relevant EULAR task forces will be looking at these data, but they’ll be looking at the whole range of literature to see whether change is necessary.”

Good-quality inflammatory disease control will certainly contribute to reducing vascular risk, “but we should not make the assumption that it will be sufficient,” he cautioned. “We still have to be very careful in addressing so called conventional risk factors, but in particular thinking about obesity and cardiometabolic syndrome to be sure that when those are present, that we detect them and we treat them appropriately.”

As to who is best placed to manage a patient’s cardiovascular risk profile, Dr. McInnes said: “I think the rheumatologist has a responsibility to make sure that as much of the patient’s disease spectrum is being treated as possible.”

“As a rheumatologist, I would like to know that those elements of a patient’s disease presentation are being addressed,” whether that is by a primary care physician, cardiologist, diabetologist, or other specialist involved in the optimal management of the patient.

A re-evaluation of cardiovascular risk management guidelines intended for use by rheumatologists may be warranted based on findings from a recently published population-based study of the risks for 12 different cardiovascular disease outcomes in patients with autoimmune diseases.

“The notion that patients with rheumatic diseases are at increased risk of developing cardiovascular diseases has been ongoing for many years,” Nathalie Conrad, PhD, and coauthors wrote in a viewpoint article in Annals of the Rheumatic Diseases.

This has “sparked much debate concerning whether and when to initiate cardiovascular prevention therapies,” they said.

Dr. Conrad was first author on the population-based study published in The Lancet in August 2022 that used linked primary and secondary care records from datasets in the U.K. Clinical Practice Research Datalink involving individuals who were recently diagnosed with any of 19 different autoimmune diseases during an 18-year period stretching from 2000 to 2017 but free of cardiovascular disease until at least 12 months after incident autoimmune disease. “Every single autoimmune disorder we looked at was associated with increased cardiovascular risk,” Dr. Conrad, of the department of public health and primary care at Catholic University Leuven (Belgium), said in an interview.

Not only was the risk for cardiovascular disease increased for people with rheumatic diseases by an average of 68%, compared with people without rheumatic diseases, but also the whole spectrum of cardiovascular disorders was seen.

“We saw increases in thromboembolic diseases, degenerative heart diseases, and heart inflammation,” Dr. Conrad said.
 

Large datasets examined

The idea for the epidemiologic study came from mounting evidence for cardiovascular disease risk among people with autoimmune diseases but not enough to support the design of specific prevention measures.

Dr. Conrad’s Lancet study examined electronic health records of 446,449 individuals with autoimmune diseases and matched them to 2,102,830 individuals without autoimmune disease. This included 160,217 individuals with seven rheumatic diseases: rheumatoid arthritis, polymyalgia rheumatica, vasculitis, systemic lupus erythematosus, Sjögren’s syndrome, ankylosing spondylitis, and systemic sclerosis.

In addition to looking for any evidence of cardiovascular disease, Dr. Conrad and coauthors looked at 12 specific outcomes: atherosclerotic diseases, peripheral arterial disease, stroke or transient ischemic attack, heart failure, valve disorders, thromboembolic disease, atrial fibrillation or flutter, conduction system disease, supraventricular arrhythmias, aortic aneurysm, myocarditis and pericarditis, and infective endocarditis.
 

CV risk in rheumatic diseases

As might be expected, “greater magnitudes of risk” were seen for individuals with systemic lupus erythematosus and systemic sclerosis than for people in the general population, with the chances of cardiovascular disease being two to four times higher. But what perhaps wasn’t expected was that all rheumatic diseases carried an increased risk for heart or vascular-related problems.

Furthermore, the increased risk could not solely be accounted for by the presence of traditional risk factors, such as blood pressure, smoking, or obesity.

“The background here is that any context of systemic inflammation would be predicted to lead to an increased vascular risk,” Iain McInnes, MD, PhD, professor of medicine and rheumatology at the University of Glasgow, said in an interview. Dr. McInnes was a coauthor of the viewpoint article in Annals of the Rheumatic Diseases.

“The implication is that there may well be increased vascular risk across the whole range of immune-mediated inflammatory diseases,” he added. “We should not, however, infer the magnitude of risk will be the same for each disease.”

What is more intriguing, Dr. McInnes said, is that “we don’t know yet whether there’s one final common pathway that leads to the blood vessel being damaged or whether different diseases might contribute different pathways.”

He added: “A question for the future is to see what are those mechanisms that drive risk across different diseases? And the reason that matters, of course, is that we might want to think about the effectiveness of different therapeutic interventions.”
 

Determining cardiovascular risk

Dr. Conrad and associates in their viewpoint article suggested that an update to the European Alliance of Associations for Rheumatology guidelines for cardiovascular risk management of rheumatic and musculoskeletal diseases (RMDs) could tailor cardiovascular risk scores to certain diseases.

They suggested that the guidelines could consider a risk multiplier of 2.5 for systemic sclerosis, 2.0 for lupus, and 1.5 for any other rheumatic disease.

“We argue that [EULAR] recommendations should consider this new evidence of poorer cardiovascular health in numerous RMDs and envisage cardiovascular screening and associated prevention measures,” Dr. Conrad said.

While they recognize that risk multipliers aren’t perfect, “they are the best available option until personalized risk prediction tools are developed specifically for patients with RMDs.”
