Patients with rheumatic disease are at least half as likely to develop long COVID after a SARS-CoV-2 infection if they have been fully vaccinated against COVID-19, according to research published in Annals of the Rheumatic Diseases (2022 Nov 28. doi: 10.1136/ard-2022-223439).

“Moreover, those who were vaccinated prior to getting COVID-19 had less pain and fatigue after their infection,” Zachary S. Wallace, MD, MSc, an assistant professor of medicine at Harvard Medical School, Boston, and a study author, said in an interview. “These findings reinforce the importance of vaccination in this population.”

Messaging around the value of COVID vaccination has been confusing for some with rheumatic disease “because our concern regarding a blunted response to vaccination has led many patients to think that they do not provide much benefit if they are on immunosuppression,” Dr. Wallace said. “In our cohort, which included many patients on immunosuppression of varying degrees, being vaccinated was quite beneficial.”

Leonard H. Calabrese, DO, director of the R.J. Fasenmyer Center for Clinical Immunology and a professor of medicine at the Cleveland Clinic, said in an interview that the study is an “extremely important contribution to our understanding of COVID-19 and its pattern of recovery in patients with immune-mediated inflammatory diseases [IMIDs].” Remaining unanswered questions are “whether patients with IMIDs develop more frequent PASC [post–acute sequelae of COVID-19] from COVID-19 and, if so, is it milder or more severe, and does it differ in its clinical phenotype?”
 

Long COVID risk assessed at 4 weeks and 3 months after infection

The researchers prospectively tracked 280 adult patients in the Mass General Brigham health care system in the greater Boston area who had systemic autoimmune rheumatic diseases and had an acute COVID-19 infection between March 2020 and July 2022. Patients were an average 53 years old, and most were White (82%) and female (80%). More than half (59%) had inflammatory arthritis, a quarter (24%) had connective tissue disease, and most others had a vasculitis condition or multiple conditions.

A total of 11% of patients were unvaccinated, 28% were partially vaccinated with one mRNA COVID-19 vaccine dose, and 41% were fully vaccinated with two mRNA vaccine doses or one Johnson & Johnson dose. The 116 fully vaccinated patients were considered to have a breakthrough infection while the other 164 were considered to have a nonbreakthrough infection. The breakthrough and nonbreakthrough groups were similar in terms of age, sex, race, ethnicity, smoking status, and type of rheumatic disease. Comorbidities were also similar, except obesity, which was more common in the non–breakthrough infection group (25%) than the breakthrough infection group (10%).

The researchers queried patients on their COVID-19 symptoms, how long symptoms lasted, treatments they received, and hospitalization details. COVID-19 symptoms assessed included fever, sore throat, new cough, nasal congestion/rhinorrhea, dyspnea, chest pain, rash, myalgia, fatigue/malaise, headache, nausea/vomiting, diarrhea, anosmia, dysgeusia, and joint pain.

Patients completed surveys about symptoms at 4 weeks and 3 months after infection. Long COVID, or PASC, was defined as any persistent symptom at the times assessed.
 

Vaccinated patients fared better across outcomes

At 4 weeks after infection, 41% of fully vaccinated patients had at least one persistent symptom, compared with 54% of unvaccinated or partially vaccinated patients (P = .04). At 3 months after infection, 21% of fully vaccinated patients had at least one persistent symptom, compared with 41% of unvaccinated or partially vaccinated patients (P < .0001).

Vaccinated patients were half as likely to have long COVID at 4 weeks after infection (adjusted odds ratio, 0.49) and 90% less likely to have long COVID 3 months after infection (aOR, 0.1), after adjustment for age, sex, race, comorbidities, and use of any of four immune-suppressing medications (anti-CD20 monoclonal antibodies, methotrexate, mycophenolate, or glucocorticoids).

Fully vaccinated patients with breakthrough infections had an average 21 additional days without symptoms during follow-up, compared with unvaccinated and partially vaccinated patients (P = .04).

Reduced risk of long COVID did not change for vaccinated patients after sensitivity analyses for those who did not receive nirmatrelvir/ritonavir (Paxlovid) or monoclonal antibodies, those who didn’t receive any COVID-19-related treatment, those who completed their questionnaires within 6 months after infection, and those who were not hospitalized.

“One important message is that among those who did get PASC, the severity appears similar among those with and without a breakthrough infection,” Dr. Wallace said. “This highlights the need for ongoing research to improve recognition, diagnosis, and treatment of PASC.”

Many more breakthrough infections (72%) than nonbreakthrough infections (2%) occurred during Omicron. The authors acknowledged that different variants might play a role in different long COVID risks but said such potential confounding is unlikely to fully explain the results.

“Even with data suggesting that the Omicron variants may be intrinsically less severe, vaccination still has an impact on severity of infection, rates of hospitalization, and other outcomes and thus may play a role in the risk of PASC,” lead author Naomi Patel, MD, an instructor at Harvard Medical School and a rheumatologist at Massachusetts General Hospital, said in an interview. “A study evaluating the proportions with PASC by vaccination status during the time in which a single variant is predominant, such as the early Omicron era, could help to better assess the more isolated impact of vaccination on PASC.”

Dr. Calabrese said he is convinced that Omicron infections are less likely to result in more severe forms of acute COVID than pre-Omicron infections, and he suspects Omicron infections are also less likely to result in long COVID, although less evidence currently supports this hypothesis.

Hospitalization was more common in unvaccinated/partly vaccinated patients than in vaccinated patients (27% vs. 5%; P = .001). Although pain and fatigue were lower in those with breakthrough infections, functional scores and health-related quality of life were similar in both groups.

Some symptoms significantly differed between vaccinated and unvaccinated/partly vaccinated groups, possibly caused partly by different variants. Nasal congestion was more common (73%) in those with breakthrough infections than in those with nonbreakthrough infections (46%; P < .0001). Those who were unvaccinated/partly vaccinated were significantly more likely to have loss of smell (46% vs. 22%) or taste (45% vs. 28%) or to have joint pain (11% vs. 4%).

Treatment with nirmatrelvir/ritonavir was also more common in vaccinated patients (12%) than in unvaccinated/partly vaccinated patients (1%; P < .0001), as was treatment with monoclonal antibodies (34% vs. 8%; P < .0001).

The study was limited by its low diversity and being at a single health care system, the authors said. Study coauthor Jeffrey A. Sparks, MD, MMSc, an assistant professor of medicine at Brigham and Women’s Hospital and Harvard Medical School, said in an interview that the group is planning additional studies as their cohort grows, including “investigating the relationships between COVID-19 and specific rheumatic diseases and immunomodulating medications, expansion of autoimmunity and systemic inflammation, and lung damage among specific patient populations.”

Dr. Calabrese said it will be important for follow-up study of the symptomatic patients to “determine how many of these patients will fit the clinical picture of long COVID or long-haul phenotypes over the months and years ahead, including documenting exertional malaise and quality of life.

This study only assessed patients who received zero, one, or two doses of a vaccine, but many patients with rheumatic disease today will likely have received booster doses. However, Dr. Calabrese said it would be difficult to quantify whether a third, fourth, or fifth dose offers additional protection from long-term COVID complications after full vaccination or hybrid vaccination.

Mickey Research Scholar Fund, and the Llura Gund Award for Rheumatoid Arthritis Research and Care.

Competition between five biologic drugs and their skinny-label biosimilars saved Medicare an estimated $1.5 billion during 2015-2020. But these savings accruing to Medicare and the availability of those and other biosimilars through skinny labeling is under threat from recent court rulings, according to a research letter published online in JAMA Internal Medicine.

The authors highlighted the need for such savings by noting that, while biologics comprise less than 5% of prescription drug use, their price tag amounts to about 40% of U.S. drug spending, Biologic manufacturers often delay the availability of biosimilars for additional years beyond the original patent expiration through further patents for supplemental indications. To provide a counterbalance, federal law allows the Food and Drug Administration to approve “skinny-label” generics and biosimilars that carve out patent-protected indications or regulatory exclusivities. But once a generic drug reaches the market through this process with a skinny label, it may often be substituted for indications that go beyond the ones listed on the skinny label. In fact, some state laws mandate that pharmacists substitute interchangeable generics for brand-name drugs, helping to decrease drug prices. In response to legal threats to the skinny-label pathway, Alexander C. Egilman and colleagues at Brigham and Women’s Hospital and Harvard Medical School, both in Boston, assessed the frequency of approval and marketing of skinny-label biosimilars from 2015 to 2021 and the resultant savings to Medicare.

TheaDesign/Thinkstock

The authors estimated annual Part B (clinician-administered) savings from skinny-label biosimilars through 2020 by comparing actual biologic and skinny-label biosimilar spending with estimated biologic spending without competition using the Medicare Dashboard. They assumed that the unit price of the biologic would increase at its 5-year compound annual growth rate prior to competition.

In that period, the FDA approved 33 biosimilars linked to 11 biologics. Among them, 22 (66.7%) had a skinny label. Of 21 biosimilars marketed before 2022, 13 (61.9%) were launched with a skinny label. Of the 8 biologics linked to these 21 biosimilars, 5 of the first-to-market biosimilars had skinny labels (bevacizumab, filgrastim, infliximab, pegfilgrastim, and rituximab), leading to earlier competition through 2021.

The estimated $1.5 billion in savings to Medicare from these skinny-label biosimilars over the 2015-2020 span represents 4.9% of the $30.2 billion that Medicare spent on the five biologics during this period. The researchers pointed out that once adalimumab (Humira) faces skinny-label biosimilar competition in 2023, savings will likely grow substantially.

In response to the research letter, an editor’s note by JAMA Internal Medicine Editorial Fellow Eric Ward, MD, and JAMA Internal Medicine Editor at Large and Online Editor Robert Steinbrook, MD, stated that, between 2015 and 2019, 24 (43%) of 56 brand-name drugs had competition from skinny-labeled generic formulations after first becoming available as generics.

The editors also referenced a JAMA Viewpoints article from 2021 that reviewed the most recent case challenging the skinny-label pathway in which GlaxoSmithKline sued Teva for its marketing of a skinny-label generic of the brand-name beta-blocker carvedilol (Coreg) that the plaintive claimed “induced physicians to prescribe carvedilol for indications that had been carved out by Teva’s skinny label, thus infringing GlaxoSmithKline’s patents.” A $235 million judgment against Teva was overturned by a district court and then reversed again by a Federal Circuit court that, after receiving criticism, reconsidered the case, and a panel affirmed the judgment against Teva.

“The Federal Circuit panel’s decision has the potential to put generic drugs that fail to adequately carve out indications from the brand name labeling at risk for damages related to infringement,” the authors wrote. Similar claims of infringement are being heard in other courts, they wrote, and they urged careful targeting of skinny-label carveouts, and suggest also that challenges to the arguments used against Teva focus on preservation of First Amendment rights as protection for lawful and accurate speech in drug labels.

“The legal uncertainties are likely to continue, as manufacturers pursue novel and complex strategies to protect the patents and regulatory exclusivities of brand-name drugs and biologics,” Dr. Ward and Dr. Steinbrook wrote, adding that “the path forward is for Congress to enact additional legislation that reaffirms and strengthens the permissibility of skinny labeling.”

The research letter’s corresponding author, Ameet Sarpatwari, PhD, JD, assistant professor at Harvard Medical School, and assistant director for the Harvard Program On Regulation, Therapeutics, And Law, echoed concerns over the Teva case in an interview. “There has certainly been concern that should the appellate decision stand, there will be a chilling effect. As the lone dissenter in that case noted, ‘no skinny-label generic is safe.’ I think many generic and biosimilar manufacturers are awaiting to see whether the Supreme Court will take the case.”

He added: “I do not believe the likelihood of skinny-label-supportive legislation making it through Congress will be greatly diminished in a divided Congress. Democrats and Republicans alike should seek to promote competition in the marketplace, which is what the skinny-labeling pathway accomplishes.”

The authors reported no relevant conflicts of interest. The research was funded by a grant from Arnold Ventures.

The editors also referenced a JAMA Viewpoints article from 2021 that reviewed the most recent case challenging the skinny-label pathway in which GlaxoSmithKline sued Teva for its marketing of a skinny-label generic of the brand-name beta-blocker carvedilol (Coreg) that the plaintive claimed “induced physicians to prescribe carvedilol for indications that had been carved out by Teva’s skinny label, thus infringing GlaxoSmithKline’s patents.” A $235 million judgment against Teva was overturned by a district court and then reversed again by a Federal Circuit court that, after receiving criticism, reconsidered the case, and a panel affirmed the judgment against Teva.

“The Federal Circuit panel’s decision has the potential to put generic drugs that fail to adequately carve out indications from the brand name labeling at risk for damages related to infringement,” the authors wrote. Similar claims of infringement are being heard in other courts, they wrote, and they urged careful targeting of skinny-label carveouts, and suggest also that challenges to the arguments used against Teva focus on preservation of First Amendment rights as protection for lawful and accurate speech in drug labels.

“The legal uncertainties are likely to continue, as manufacturers pursue novel and complex strategies to protect the patents and regulatory exclusivities of brand-name drugs and biologics,” Dr. Ward and Dr. Steinbrook wrote, adding that “the path forward is for Congress to enact additional legislation that reaffirms and strengthens the permissibility of skinny labeling.”

The research letter’s corresponding author, Ameet Sarpatwari, PhD, JD, assistant professor at Harvard Medical School, and assistant director for the Harvard Program On Regulation, Therapeutics, And Law, echoed concerns over the Teva case in an interview. “There has certainly been concern that should the appellate decision stand, there will be a chilling effect. As the lone dissenter in that case noted, ‘no skinny-label generic is safe.’ I think many generic and biosimilar manufacturers are awaiting to see whether the Supreme Court will take the case.”

He added: “I do not believe the likelihood of skinny-label-supportive legislation making it through Congress will be greatly diminished in a divided Congress. Democrats and Republicans alike should seek to promote competition in the marketplace, which is what the skinny-labeling pathway accomplishes.”

The authors reported no relevant conflicts of interest. The research was funded by a grant from Arnold Ventures.

Competition between five biologic drugs and their skinny-label biosimilars saved Medicare an estimated $1.5 billion during 2015-2020. But these savings accruing to Medicare and the availability of those and other biosimilars through skinny labeling is under threat from recent court rulings, according to a research letter published online in JAMA Internal Medicine.

The authors highlighted the need for such savings by noting that, while biologics comprise less than 5% of prescription drug use, their price tag amounts to about 40% of U.S. drug spending, Biologic manufacturers often delay the availability of biosimilars for additional years beyond the original patent expiration through further patents for supplemental indications. To provide a counterbalance, federal law allows the Food and Drug Administration to approve “skinny-label” generics and biosimilars that carve out patent-protected indications or regulatory exclusivities. But once a generic drug reaches the market through this process with a skinny label, it may often be substituted for indications that go beyond the ones listed on the skinny label. In fact, some state laws mandate that pharmacists substitute interchangeable generics for brand-name drugs, helping to decrease drug prices. In response to legal threats to the skinny-label pathway, Alexander C. Egilman and colleagues at Brigham and Women’s Hospital and Harvard Medical School, both in Boston, assessed the frequency of approval and marketing of skinny-label biosimilars from 2015 to 2021 and the resultant savings to Medicare.

The authors estimated annual Part B (clinician-administered) savings from skinny-label biosimilars through 2020 by comparing actual biologic and skinny-label biosimilar spending with estimated biologic spending without competition using the Medicare Dashboard. They assumed that the unit price of the biologic would increase at its 5-year compound annual growth rate prior to competition.

In that period, the FDA approved 33 biosimilars linked to 11 biologics. Among them, 22 (66.7%) had a skinny label. Of 21 biosimilars marketed before 2022, 13 (61.9%) were launched with a skinny label. Of the 8 biologics linked to these 21 biosimilars, 5 of the first-to-market biosimilars had skinny labels (bevacizumab, filgrastim, infliximab, pegfilgrastim, and rituximab), leading to earlier competition through 2021.

The estimated $1.5 billion in savings to Medicare from these skinny-label biosimilars over the 2015-2020 span represents 4.9% of the $30.2 billion that Medicare spent on the five biologics during this period. The researchers pointed out that once adalimumab (Humira) faces skinny-label biosimilar competition in 2023, savings will likely grow substantially.

PHILADELPHIA – The new American College of Rheumatology Guideline for Vaccinations in Patients with Rheumatic and Musculoskeletal Diseases (RMDs) emphasizes that both adult and pediatric patients should receive recommended vaccinations whenever possible.

But the guideline, currently in press, also offers recommendations about whether and when to withhold vaccines from patients with RMDs, such as avoiding the use of live attenuated virus vaccines in patients who are on immunosuppressive drug regimens, such as conventional synthetic disease-modifying antirheumatic drugs (DMARDs), biologic DMARDs, or targeted synthetic DMARDs.

The new consensus guideline was formulated with the understanding that patients with RMDs are at increased risk for vaccine-preventable infections and more serious complications from infections, compared with the general population.

However, the guideline also acknowledges that the immunogenicity and safety of vaccines may differ among patients with RMDs, and that, depending on the patient age and disease state, individuals may benefit from modified vaccine indications, schedules, or modified medication schedules, said guideline panel member Anne Bass, MD, a rheumatologist at Hospital for Special Surgery and a professor of clinical medicine at Weill Cornell Medicine in New York, who presented the guideline with other panel members in a session outlining the recommendations at the annual meeting of the ACR.

“In addition, vaccination recommendations – since much of it relates to medications – really applies across diseases, and so the ACR felt that, rather than having vaccine recommendations tacked onto the end of treatment guidelines for each individual disease, that the topic should be discussed or tackled as a whole,” she said.

The guideline does not cover vaccinations in patients taking nonsteroidal anti-inflammatory drugs because this class of agents has minimal or no impact on antibody responses to vaccines. The guideline also does not address vaccinations against COVID-19 infections since the rapidly changing formulations would make the recommendations obsolete before they were even published, and because the U.S. Centers for Disease Control and Prevention provides up-to-date guidance on COVID-19 vaccinations in patients with compromised immunity, she said.
 

Guiding principles

The overarching principles of the guideline are to give indicated vaccines to patients with RMD whenever possible and that any decision to hold medications before or after vaccination consider the dosage used, RMD disease activity, and the patient’s risk for vaccine-preventable infection.

The guideline also states that “shared decision-making with patients is a key component of any vaccination strategy.”

Panel member Clifton O. Bingham III, MD, professor of medicine at Johns Hopkins University in Baltimore, outlined expanded indications for vaccinations against influenza, pneumococcal infections, varicella zoster virus (VZV) and human papillomavirus (HPV).
 

Influenza

The guideline conditionally recommends that patients with RMD aged 65 years and older and adults older than age 18 years who are on immunosuppressive medications should receive either high-dose or adjuvanted influenza vaccination rather than regular-dose vaccines.

“It’s recognized that the high-dose or adjuvanted vaccinations may be unavailable for patients when they’re seen in your practice,” Dr. Bingham said,” and we came out with two additional statements within the guidelines that said that any flu vaccine is recommended over no flu vaccinations, because we do know that responses are elicited, and a flu vaccination today is preferred over a flu vaccination delay.”
 

Pneumococcal vaccination

The panelists strongly recommended that patients with RMD younger than age 65 years who are on immunosuppressive medication receive pneumococcal vaccinations.

The ACR guideline is in sync with those issued by the CDC’s Advisory Committee on Immunization Practices, Dr. Bingham said. He urged audience members to visit a CDC-ACIP web page for more information on who should receive pneumococcal vaccination and when.
 

Recombinant varicella zoster

The recommendations strongly support that patients aged 18 years and over who are on immunosuppressive therapies should receive the recombinant VZV vaccine (Shingrix).

HPV

A less robust, conditional recommendation is for patients with RMDs who are between the ages of 26 and 45 years and on immunosuppressive medications to receive the HPV vaccine (if they have not already received the vaccine).

Non-live attenuated vaccines

Kevin Winthrop, MD, MPH, professor of infectious diseases and public health at Oregon Health & Science University, Portland, summarized the recommendations for managing immunosuppressive therapies in patients scheduled to receive vaccinations using killed or nonactive antigens.

“In influenza season, don’t pass up the opportunity to vaccinate,” he said, adding, “if you can wait on rituximab dosing, do it, and if you can’t, go ahead and vaccinate.”

The guidelines also recommend a 2-week methotrexate hold at the time of influenza vaccination; other DMARD dosing changes are likely not necessary at the time of vaccination, “but this is an area of fervent study, and I think in a year or two we’ll have more experimental hold data with regard to other DMARDs,” Dr. Winthrop said.

For other nonlive attenuated vaccinations, recommendations are similar to those for influenza, except with more flexible timing because these vaccinations are not seasonal. When and how to hold methotrexate is still up in the air, he said.

Additionally, it’s recommended that vaccinations be delayed in patients on high-dose prednisone until the drug is tapered to below 20 mg per day, and ideally to less than 10 mg per day, he said.
 

Live-attenuated vaccines

The guideline conditionally recommends deferring live-attenuated vaccines in patients on immunosuppressive drugs. It also recommends holding these medications “for an appropriate period before” vaccination and for 4 weeks afterward.

“Although the evidence around conventional synthetic DMARDs and TNF inhibitors is reassuring in terms of their safety at the time of live attenuated vaccines, as you can see the number of studies is quite small, and so the voting panel conditionally recommend against administering live-attenuated virus vaccines to patients who are on conventional synthetics, biologic, or targeted DMARDs,” Dr. Bass said.
 

In utero exposures

Most women with RMD who have recently given birth will consult their general pediatricians rather than rheumatologists for infant vaccinations, but pediatricians may not be aware of the affect that in utero exposures to biologic DMARDs can have on vaccine safety and immunogenicity in infants, Dr, Bass said.

“It’s important that you, as a provider, give your recommendations regarding infant rotavirus vaccination after in utero exposure to the pregnant rheumatic disease patient prior to delivery, and let that patient know that this is something that they should share with their pediatrician to be,” she advised audience members.
 

Getting the message out

In an interview, session moderator and guidelines panelist Lisa F. Imundo, MD, director of the center for adolescent rheumatology at Columbia University in New York, noted that rheumatologists don’t usually have the full schedule of pediatric vaccinations in stock and often leave the decisions about what to give – and when – to general practitioners.

“Pediatric rheumatologists sometimes will give patients flu vaccinations because they’re a high-risk population of patients, and we want to make sure that they’re getting it in a timely manner,” she said.

In addition, because pneumococcal polysaccharide vaccines are not indicated in the general pediatric population, children on biologic DMARDs who have completed their standard series of pneumococcal conjugate vaccines (PCV13 or PVC15) are recommended to get a 23-valent pneumococcal polysaccharide vaccine, Dr. Imundo said.

She also noted that communication between pediatric rheumatologists and general practitioners about vaccine recommendations can be challenging.

“It’s a huge issue, figuring out how we’re going to communicate all of this information to our pediatric colleagues,” she said. “With individual patients, we may sometimes remind doctors, especially with our younger patients who haven’t gotten their live vaccines, that they really shouldn’t get live vaccines until they’re off medication or until we arrange holding medication for some period of time.”

She said that ACR vaccine committee members are working with infectious disease specialists and guideline developers for the American Academy of Pediatrics to ensure guidelines include the most important vaccination recommendations for pediatric patients with RMDs.

The development process for the guidelines was supported by the ACR. Dr. Bass reported no relevant disclosures, Dr. Bingham disclosed consulting activities, grant/research support, and royalties from various corporate entities. Dr. Winthrop disclosed consulting activities for and research funding from various companies. Dr. Imundo reported no relevant financial relationships.

PHILADELPHIA – Women with spondyloarthritis (SpA) who are desiring pregnancy may want to consider decreasing use or discontinuing use (with supervision) of nonsteroidal anti-inflammatory drugs before conception, new data suggest.

Researchers have found a connection between NSAID use and age and a significantly longer time to conception among women with spondyloarthritis. Sabrina Hamroun, MMed, with the rheumatology department at the University Hospital Cochin, Paris, presented the findings during a press conference at the annual meeting of the American College of Rheumatology.

Subfertility group took an average of 16 months to get pregnant

Subfertility was observed in 40 (45.4%) of the women, with an average time to conception of 16.1 months. A woman was considered subfertile if her time to conception was more than 12 months or if she did not become pregnant.

The average preconception Bath Ankylosing Spondylitis Disease Activity Index score was 2.9 (+/- 2.1), the authors noted. The average age of the participants was 32 years.

Twenty-three patients were treated with NSAIDs, eight with corticosteroids, 12 with conventional synthetic disease-modifying antirheumatic drugs, and 61 with biologics.

Researchers adjusted for factors including age, body mass index, disease duration and severity, smoking, form of SpA (axial, peripheral, or both), and medication in the preconception period.

They found significant associations between longer time to conception and age (hazard ratio, 1.22; 95% confidence interval, 1.08-1.40; P < .001), and a much higher hazard ratio with the use of NSAIDs during preconception (HR, 3.01; 95% CI, 2.15-3.85; P = .01).

Some data unavailable

Ms. Hamroun acknowledged that no data were available on the frequency of sexual intercourse or quality of life, factors that could affect time to conception. Women were asked when they discontinued contraceptive use and actively began trying to become pregnant.

She stated that information on the dose of NSAIDs used by the patients was incomplete, noting, “We were therefore unable to adjust the results of our statistical analyses on the dose used by patients.”

Additionally, because the study participants were patients at tertiary centers in France and had more severe disease, the results may not be generalizable to all women of childbearing age. Patients with less severe SpA are often managed in outpatient settings in France, she said.

When asked about alternatives to NSAIDs, Ms. Hamroun said that anti–tumor necrosis factor agents with low placental passage may be a good alternative “if a woman with long-standing difficulties to conceive needs a regular use of NSAIDs to control disease activity, in the absence of any other cause of subfertility.”

The patient’s age must also be considered, she noted.

“A therapeutic switch may be favored in a woman over 35 years of age, for example, whose fertility is already impaired by age,” Ms. Hamroun said.

As for the mechanism that might explain the effects of NSAIDs on conception, Ms. Hamroun said that prostaglandins are essential to ovulation and embryo implantation and explained that NSAIDs may work against ovulation and result in poor implantation (miscarriage) by blocking prostaglandins.

She pointed out that her results are in line with the ACR’s recommendation to discontinue NSAID use during the preconception period in women with SpA who are having difficulty conceiving.
 

Control before conception is important

Sinead Maguire, MD, a clinical and research fellow in the Spondylitis Program at Toronto (Ont.) Western Hospital who was not part of the study, said the study highlights the importance of optimizing disease control before conception.

“There are a number of things rheumatologists can do to support our SpA patients when they are trying to conceive,” she told this news organization. “One of the most important issues to address is ensuring their SpA is in remission and continues to remain so. For that reason, if a woman is requiring regular NSAIDs for symptom control, the results of this study might encourage me to consider a biologic agent sooner to ensure remission.”

She urged women who want to become pregnant to discuss medications with their rheumatologist before trying to conceive.

“It is very exciting to see studies such as this so that rheumatologists can provide answers to our patients’ questions with evidence-based advice,” she said.

Ms. Hamroun and several coauthors had no disclosures.

PHILADELPHIA – Women with spondyloarthritis (SpA) who are desiring pregnancy may want to consider decreasing use or discontinuing use (with supervision) of nonsteroidal anti-inflammatory drugs before conception, new data suggest.

Researchers have found a connection between NSAID use and age and a significantly longer time to conception among women with spondyloarthritis. Sabrina Hamroun, MMed, with the rheumatology department at the University Hospital Cochin, Paris, presented the findings during a press conference at the annual meeting of the American College of Rheumatology.

Subfertility group took an average of 16 months to get pregnant

Subfertility was observed in 40 (45.4%) of the women, with an average time to conception of 16.1 months. A woman was considered subfertile if her time to conception was more than 12 months or if she did not become pregnant.

The average preconception Bath Ankylosing Spondylitis Disease Activity Index score was 2.9 (+/- 2.1), the authors noted. The average age of the participants was 32 years.

Twenty-three patients were treated with NSAIDs, eight with corticosteroids, 12 with conventional synthetic disease-modifying antirheumatic drugs, and 61 with biologics.

Researchers adjusted for factors including age, body mass index, disease duration and severity, smoking, form of SpA (axial, peripheral, or both), and medication in the preconception period.

They found significant associations between longer time to conception and age (hazard ratio, 1.22; 95% confidence interval, 1.08-1.40; P < .001), and a much higher hazard ratio with the use of NSAIDs during preconception (HR, 3.01; 95% CI, 2.15-3.85; P = .01).

Some data unavailable

Ms. Hamroun acknowledged that no data were available on the frequency of sexual intercourse or quality of life, factors that could affect time to conception. Women were asked when they discontinued contraceptive use and actively began trying to become pregnant.

She stated that information on the dose of NSAIDs used by the patients was incomplete, noting, “We were therefore unable to adjust the results of our statistical analyses on the dose used by patients.”

Additionally, because the study participants were patients at tertiary centers in France and had more severe disease, the results may not be generalizable to all women of childbearing age. Patients with less severe SpA are often managed in outpatient settings in France, she said.

When asked about alternatives to NSAIDs, Ms. Hamroun said that anti–tumor necrosis factor agents with low placental passage may be a good alternative “if a woman with long-standing difficulties to conceive needs a regular use of NSAIDs to control disease activity, in the absence of any other cause of subfertility.”

The patient’s age must also be considered, she noted.

“A therapeutic switch may be favored in a woman over 35 years of age, for example, whose fertility is already impaired by age,” Ms. Hamroun said.

PHILADELPHIA – When patients with inflammatory rheumatic diseases were switched from one biosimilar agent to another, treatment retention rates were high, investigators in Denmark reported.

The findings suggest patient-related factors rather than drug-related factors appear to determine whether patients will stay on the new drug, the researchers said.

One year after a Danish government-mandated switch from one infliximab (Remicade) biosimilar to another equally efficacious but less costly biosimilar, 83% of patients who had started therapy on a biosimilar (so-called “originator-naive” patients) stayed on the newly assigned therapy. And so did 92% of patients who had started on the original infliximab (“originator experienced”) before they were switched to one biosimilar and then another.

“In regards to potential baseline predictors, we found that treatment withdrawal was more frequent among originator-naive switchers and patients with higher baseline disease activity, especially [in] patient-reported outcomes, which may indicate that treatment-related outcomes may be more affected by patient-related rather than drug-related factors,” said lead author Hafsah Nabi, MD from the Danish biosimilar registry DANBIO and a PhD candidate at the Copenhagen Center for Arthritis Research.

Dr. Nabi reported the results in an oral abstract session at the annual meeting of the American College of Rheumatology.
 

Annual review of biologic agents

In Denmark, health authorities issue annual recommendations for the use of biologic agents. “And since patients receive this treatment free from the hospital, based on the tax system, the switches are made due to these cost considerations,” Dr. Nabi said in an interview.

To get the nod from Danish pharmaceutical regulators, pharmaceutical manufacturers submit drugs that have already been approved by the European Medicines Agency for consideration for treatment of specific indications, explained coauthor Merete Lund Hetland, MD, PhD, DMSc, from Rigshospitalet in Copenhagen.

“Those drugs that are then considered equally safe and effective are invited to this process where they will give their bid, and then the cheapest one will win,” she said.

The winning formulation will be able to capture about 80% of prescriptions for that indication for the coming year.
 

Awake at the switch

Dr. Nabi, Dr. Hetland, and colleagues studied how one such recent government-mandated switch from one biosimilar to another affected efficacy and patterns of care among patients with rheumatoid arthritis, psoriatic arthritis (PsA) and axial spondyloarthritis (axSpA).

To identify prior comorbidities, they drew data from the DANBIO registry, which is linked to patient specific but anonymous data from other comprehensive birth-to-death patient registries in Denmark.

They looked at all patients with RA, PsA, or axSpA who were switched from CT-P13 (Remsira, Inflectra) to GP1111 (Zessly) from April 1, 2019, to Feb. 1, 2020.

They identified a total of 1,605 patients, including 685 with RA, 314 with PsA, and 606 with axSpa. The median disease duration was 9 years, and 37% of all patients were in remission according to Clinical Disease Activity Index or Ankylosing Spondylitis Disease Activity Scale.

Of this group, 1,171 had started therapy on a biosimilar.

As noted above, 83% of patients who had never received original infliximab, and 92% of those who were originator experienced were still on the new biosimilar 1 year after the switch.

In a multivariate analysis controlling for demographic and clinical factors at baseline, the variables significantly associated with treatment withdrawal from the new biosimilar (GP11110) included previous Remicade exposure (hazard ratio, 0.36), methotrexate use (HR, 0.60), and patient-reported global visual analog scale (HR, 1.02).

Among all patients, disease activity was stable 6 months before and after the switch, Dr. Nabi said, although she did not show data to support it.
 

Patient education benefit

During the session, Jonathan Kay, MD, professor of rheumatology and chair of the division of rheumatology at the University of Massachusetts, Worcester, who was not involved the study, asked Dr. Nabi whether patients were educated about equivalent efficacy and safety of biosimilars prior to the switch. He noted that education prior to switching led to a much lower patient withdrawal rate in a similar switching study conducted in The Netherlands.

“In this study, we haven’t looked more specifically into the education and which strategies have been used prior to switching, and we also conclude in the study that there may be the presence of a nocebo effect, which can be handled by better educating the patients,” she replied.

The nocebo effect refers to the phenomenon in which a patient’s belief that a specific intervention may cause harm actually can lead to negative outcomes – in other words, the opposite of the placebo effect.

In an interview, Dr. Kay said that he is confident about the efficacy, safety, and equivalency of approved biosimilar agents.

“A biosimilar that has been reviewed and approved by a regulatory agency such as the [Food and Drug Administration or the [European Medicines Agency] should be equivalent in efficacy and comparable in safety and immunogenicity. I would be fully confident in switching from the reference product to the biosimilar,” he said.

Dr. Nabi reported that the study was partly funded by a research grant from Sandoz, the maker of GP1111. Dr. Hetland has disclosed grants from various companies, not including Sandoz. Dr. Kay disclosed consulting fees from various companies, not including Sandoz.

Therapeutic drug monitoring allowed patients with rheumatoid arthritis, psoriatic arthritis, and spondyloarthritis to reduce their dosage of tumor necrosis factor–alpha (TNF) inhibitors, based on data from 239 individuals.

Use of TNF-alpha inhibitors improves treatment response for many arthritis patients but dosage is rarely adjusted on an individual level, which may lead to unnecessary overdosing in some patients, Mogens Pfeiffer-Jensen, MD, of Aarhus (Denmark) University Hospital, and colleagues wrote.

Data from previous studies suggest that therapeutic drug monitoring (TDM) based on serum trough levels may allow for dose optimization and dose reduction in inflammatory bowel disease patients, but data in patients with arthritis are lacking, they wrote.

In a study published in the Scandinavian Journal of Rheumatology, the researchers recruited 99 patients with RA, 48 with psoriatic arthritis (PsA), and 92 with spondyloarthritis (SpA). The participants were randomized to standard care or standard care plus TDM. Serum trough levels were assessed at baseline and at every 4 months, and prescription changes or drug switches were implemented based on these levels. At baseline, 81 patients were being treated with infliximab (Remicade and biosimilars), 79 with etanercept (Enbrel), and 79 with adalimumab (Humira).

The primary endpoint was reduced drug prescription after 48 weeks.

Overall, TDM significantly reduced prescription of infliximab by 12% (P = .001) and prescription of etanercept by 15% (P = .01), compared with standard care. TDM also prolonged the interdosing intervals of etanercept by 235% (P = .02) and of adalimumab by 28% (P = .04), compared with standard care.

TDM patients taking infliximab had more frequent dose reduction and less frequent dose increases during and after the study when compared with patients who stayed with standard care; similar trends were seen with adalimumab. TDM also accelerated the switch to other biologics for patients on all three medications.

No significant differences occurred in adverse events or hospitalizations between the TDM and standard care patients.

Clinical composite scores (Disease Activity Score based on 28 joints with C-reactive protein) were reduced in patients with RA and PsA who were taking adalimumab and randomized to TDM, but no other clinical outcome differences were noted. Scores on the Health Assessment Questionnaire and global Visual Analog Scale for pain were significantly lower in patients in the TDM group who were taking infliximab and adalimumab, “indicating equally or superior sustained remission across diagnoses,” the researchers emphasized.

The findings were limited by several factors, including the variations in pathophysiology and open-label design. “However, since the TDM was based on an objective serum value and decision procedures were clear, we do not consider the potential of unconscious bias to outweigh the benefits of dose-changing abilities,” they wrote.

The researchers expressed surprise that the reduced use of TNF-alpha inhibitors did not significantly reduce adverse events or serious adverse events, compared with standard care, but they proposed that standard of care may have taken adverse events into account, because all patients had received prescriptions at least 3 months before the study.

As for clinical implications, the current costs of the biochemical assays necessary for TDM may be a barrier to implementing TDM as a standard part of daily clinical practice, the researchers added. However, the study was strengthened by the inclusion of patients with RA, PsA, and SpA, and is the first known to include patients receiving etanercept or adalimumab in an examination of TDM.

“Our data support TDM based solely on serum trough levels in [TNF-alpha inhibitors] with different pharmacokinetics as a future key player in personalized medicine for chronic rheumatoid diseases treated with biologics,” they concluded.

The study was supported by Spydspidspuljen, Region Midt, Denmark, and Department of Rheumatology, Aarhus University Hospital. The researchers had no financial conflicts to disclose.

The study was supported by Spydspidspuljen, Region Midt, Denmark, and Department of Rheumatology, Aarhus University Hospital. The researchers had no financial conflicts to disclose. 

Therapeutic drug monitoring allowed patients with rheumatoid arthritis, psoriatic arthritis, and spondyloarthritis to reduce their dosage of tumor necrosis factor–alpha (TNF) inhibitors, based on data from 239 individuals.

Use of TNF-alpha inhibitors improves treatment response for many arthritis patients but dosage is rarely adjusted on an individual level, which may lead to unnecessary overdosing in some patients, Mogens Pfeiffer-Jensen, MD, of Aarhus (Denmark) University Hospital, and colleagues wrote.

Data from previous studies suggest that therapeutic drug monitoring (TDM) based on serum trough levels may allow for dose optimization and dose reduction in inflammatory bowel disease patients, but data in patients with arthritis are lacking, they wrote.

In a study published in the Scandinavian Journal of Rheumatology, the researchers recruited 99 patients with RA, 48 with psoriatic arthritis (PsA), and 92 with spondyloarthritis (SpA). The participants were randomized to standard care or standard care plus TDM. Serum trough levels were assessed at baseline and at every 4 months, and prescription changes or drug switches were implemented based on these levels. At baseline, 81 patients were being treated with infliximab (Remicade and biosimilars), 79 with etanercept (Enbrel), and 79 with adalimumab (Humira).

The primary endpoint was reduced drug prescription after 48 weeks.

Overall, TDM significantly reduced prescription of infliximab by 12% (P = .001) and prescription of etanercept by 15% (P = .01), compared with standard care. TDM also prolonged the interdosing intervals of etanercept by 235% (P = .02) and of adalimumab by 28% (P = .04), compared with standard care.

TDM patients taking infliximab had more frequent dose reduction and less frequent dose increases during and after the study when compared with patients who stayed with standard care; similar trends were seen with adalimumab. TDM also accelerated the switch to other biologics for patients on all three medications.

No significant differences occurred in adverse events or hospitalizations between the TDM and standard care patients.

Clinical composite scores (Disease Activity Score based on 28 joints with C-reactive protein) were reduced in patients with RA and PsA who were taking adalimumab and randomized to TDM, but no other clinical outcome differences were noted. Scores on the Health Assessment Questionnaire and global Visual Analog Scale for pain were significantly lower in patients in the TDM group who were taking infliximab and adalimumab, “indicating equally or superior sustained remission across diagnoses,” the researchers emphasized.

The findings were limited by several factors, including the variations in pathophysiology and open-label design. “However, since the TDM was based on an objective serum value and decision procedures were clear, we do not consider the potential of unconscious bias to outweigh the benefits of dose-changing abilities,” they wrote.

The researchers expressed surprise that the reduced use of TNF-alpha inhibitors did not significantly reduce adverse events or serious adverse events, compared with standard care, but they proposed that standard of care may have taken adverse events into account, because all patients had received prescriptions at least 3 months before the study.

As for clinical implications, the current costs of the biochemical assays necessary for TDM may be a barrier to implementing TDM as a standard part of daily clinical practice, the researchers added. However, the study was strengthened by the inclusion of patients with RA, PsA, and SpA, and is the first known to include patients receiving etanercept or adalimumab in an examination of TDM.

“Our data support TDM based solely on serum trough levels in [TNF-alpha inhibitors] with different pharmacokinetics as a future key player in personalized medicine for chronic rheumatoid diseases treated with biologics,” they concluded.

Vedolizumab (Entyvio) and ustekinumab (Stelara) appear to be equally effective for extraintestinal manifestation (EIM) of inflammatory bowel disease (IBD), according to results of a retrospective study published online in Digestive and Liver Disease.

Between 25% and 40% of patients with IBD experience EIM, which reduces quality of life, according to the Crohn’s & Colitis Foundation. EIM commonly involves the joints, skin, bones, eyes, kidney, and liver. Anemia is another extraintestinal complication.

Until now, it’s been unclear whether vedolizumab and ustekinumab are equally effective for treating EIM.

Vedolizumab specifically targets the gastrointestinal tract, a potential disadvantage in reducing EIM, while ustekinumab is thought to have a systemic effect, a potential treatment advantage, Moran Livne-Margolin, MD, and colleagues, Chaim Sheba Medical Center, Ramat Gan, Israel, point out.

To investigate, they included 111 adults with IBD who were treated at the medical center between 2015 and 2021 – 53 with vedolizumab and 58 with ustekinumab. Before starting treatment, all of them had active EIM, most commonly arthralgia (84%).

After 6 weeks of treatment, 66% of patients in both groups had a clinical response to their intestinal disease.

After 14 and 26 weeks of treatment, clinical response rates were 59% and 50%, respectively, with vedolizumab, and 48% and 41%, respectively, with ustekinumab.

Over 52 weeks, both biologics were equally effective against the intestinal disease, with clinical response rates of 42% with vedolizumab and 44% with ustekinumab.

A similar pattern emerged when looking at improvement in EIM.

At week 6, 44% of patients taking vedolizumab and 35% taking ustekinumab had improvement in EIM, with no significant difference between the two biologics (P = .4).

At week 14, rates of improvement in EIM were 43% for vedolizumab and 33% for ustekinumab (P = .39); at 26 weeks, rates were 39% and 33%, respectively (P = .6); and at 52 weeks, rates were 34% and 36% (P = .9).

Researchers also found a significant positive correlation between improvement of the intestinal disease and clinical improvement of EIM at each time point.

Ustekinumab is usually preferred in patients with EIM, Dr. Livne-Margolin and colleagues note. But their findings “may raise some questions whether ustekinumab is, in fact, a better choice in those specific patients.”

Limitations of the study include its retrospective design and small cohort size.

Additionally, vedolizumab is given intravenously in the clinic and mandates patients to have a routine checkup every 1-2 months, whereas ustekinumab can be given at home. As a result, data were missing on some of the patients treated with ustekinumab during the follow-up.

Another limitation is that most of the patients had articular complaints with a small presentation of other EIM.

Also, most of the patients had Crohn’s disease, with only one patient with ulcerative colitis in the ustekinumab group, compared with 12 in the vedolizumab group.

Finally, patients treated with ustekinumab had more experience with anti-TNF treatment, compared with the vedolizumab group, which might have influenced the results with a negative bias toward ustekinumab.

The study had no specific funding. Three authors have disclosed relationships with Janssen, which makes ustekinumab.

The United States Food and Drug Administration has approved the Janus kinase (JAK) inhibitor upadacitinib (Rinvoq) for adults with nonradiographic axial spondyloarthritis (nr-axSpA) who have objective signs of inflammation and who have had an inadequate response to or are intolerant of one or more tumor necrosis factor (TNF) inhibitors, according to an announcement from the manufacturer, AbbVie.

The indication is the sixth in the United States for the JAK inhibitor. Upadacitinib 15 mg once daily is already approved in the United States for adults with moderately to severely active rheumatoid arthritis, active psoriatic arthritis (PsA), and active ankylosing spondylitis (AS). All these indications are for patients who have had an inadequate response to or are intolerant of one or more TNF inhibitors.

Upadacitinib is now the only JAK inhibitor that has been approved for both nr-axSpA and AS.

“Many patients living with nr-axSpA continue to experience symptoms and are unable to control disease with current treatments. In the SELECT-AXIS 2 trials, Rinvoq demonstrated efficacy in both nr-axSpA and AS with safety that was consistent across indications,” Atul Deodhar, MD, lead investigator of the trial, said in the announcement. “Today’s FDA approval offers an important new therapeutic option for patients and their caregivers to help take control of their symptoms and disease.”

Upadacitinib is also approved at a dose of 15 mg once daily for adults and children 12 years of age and older who weigh at least 40 kg and who have refractory, moderate to severe atopic dermatitis that is not adequately controlled with other systemic drug products, including biologics, or when use of those therapies is inadvisable.

It is approved as well at 45 mg once daily for 8 weeks as an induction therapy for adult patients with moderately to severely active ulcerative colitis who have had an inadequate response to or are intolerant of one or more TNF blockers. Following induction therapy for patients with ulcerative colitis, the recommended dose for maintenance treatment is 15 mg once daily, but a dose of 30 mg once daily may be considered for patients with refractory, severe, or extensive disease.

The FDA’s decision is supported by data from the phase 3 SELECT-AXIS 2 clinical trial, which assessed the efficacy, safety, and tolerability of upadacitinib in adults with active nr-axSpA.

Nearly half of patients treated with upadacitinib had achieved 40% improvement in Assessment of Spondyloarthritis International Society response criteria (ASAS 40), the primary endpoint, at week 14, compared with placebo (44.9% vs. 22.3%). These responses were observed as early as 2 weeks after initiation of therapy. The safety profile was consistent with what’s known in patients with RA, PsA, and AS.

Upadacitinib can lower the ability to fight infections. Serious infections, some fatal, have occurred, including tuberculosis and infections caused by bacteria, fungi, or viruses. It is associated with an increased risk of death and major cardiovascular events in people aged 50 and older who have at least one heart disease risk factor, and it is associated with an increased risk of some cancers, including lymphoma and skin cancers.

Syndesmophytes are not present in a subgroup of patients with ankylosing spondylitis (AS) and sacroiliac (SI) joint fusion who have had the disease for 20 years or longer, according to findings from a nested case-control study.

Syndesmophytes did not occur in only 23 (7%) of 354 patients, and these patients without spinal-fusing bone growths were less likely to be female but very likely to be HLA-B27 positive, Lauren K. Ridley, MD, a rheumatologist at the University of Texas Health Science Center at Houston, and colleagues reported in The Journal of Rheumatology.

“Women appear to have a different phenotype in AS; we found that they are less likely to form syndesmophytes despite fused SI joints with at least 20 years of disease duration. We do not understand the reasons behind these differences among the possibilities of genetic, hormonal, and bio-mechanical factors,” the authors wrote.

AS is a heterogenous disease that affects different people in various ways, Dr. Ridley noted. “Prior research has shown that and hasn’t really elucidated how different people manifest their disease. Previous research has shown that women tend to have more nonradiographic spondylitis,” Dr. Ridley said in an interview.

“This is still a very heterogenous disease. We don’t fully understand it, and we don’t know why some patients present with SI joint disease [and] no syndesmophytes, or some patients have the opposite. Truly, we do need to do more studies to find out why some patients behave differently and if there are ways we can try to alter that,” Dr. Ridley continued.

The researchers evaluated 354 patients from the Prospective Study of Outcomes in Ankylosing Spondylitis (PSOAS). Of these patients, 23 did not have syndesmophytes. Patients were selected if they had fused SI joints (bilateral grade 4 sacroiliac joint disease) and had a disease course lasting 20 years or more. The researchers identified risk factors for syndesmophytes using classification and regression trees (CART) analysis and then reassessed their validity with univariable logistic regression models.

All 23 patients who had no syndesmophytes were HLA-B27 positive, and all patients older than 45 years at symptom onset had syndesmophytes.

The results also highlighted age of disease onset as an important predictor of syndesmophytes in males. Syndesmophytes were less likely to be reported in males with a disease onset at 16 years or younger.

The presence of syndesmophytes was linked with an age older than 16 years at symptom onset (OR, 2.72; 95% confidence interval, 1.15-6.45), and syndesmophytes were less likely to occur among HLA-B27 positive individuals (P = .03).

Females were less likely than males to have syndesmophytes, as verified by univariable analysis (odds ratio, 0.17; 95% confidence interval, 0.07-0.41).

“There is likely a complex interplay of factors leading to differences in radiographic damage between the sacroiliac joints and the spine in AS, and it is interesting to consider if HLA-B27 may have more effect on sacroiliac joint damage than spinal damage,” the authors noted.

Some limitations of the study include the researchers’ choice to compare a subtype with overt spinal involvement and a subtype with limited spinal involvement when other criteria could have been used to separate cases, and their use of the modified Stoke Ankylosing Spondylitis Scoring System (mSaSSS) to examine radiographic changes over time, as the mSaSSS does not take into account radiographic variation in the zygaphophyseal joints and thoracic spine (and were not part of the dataset). Another limitation was the relatively small cohort size, the researchers noted.

“This was a small study, and further studies are needed to elucidate why AS disease may behave differently in this and other subgroups,” Dr. Ridley and colleagues concluded.
 

Expert commentary

Researchers agree that spinal structural damage is a predictor of further damage in patients with radiographic AS, Marina Magrey, MD, the Roland W. Moskowitz Professor in Rheumatic Diseases at Case Western Reserve University, Cleveland, said in an interview. She pointed out that previous literature has shown that longer disease durations make it more likely that patients will have syndesmophytes.

Previous research has also shown that there was an association between structural damage in the SI joints and the function and mobility of the spine. This observation was independent of the disease activity and prior structural damage in the spine, Dr. Magrey noted.

“This is a very complex disease with very diverse manifestations. Traditionally, it was thought to be a disease of men, but now we believe it is equally common between men and women. The burden is equal between men and women, and they need to be treated equally. Both of them need to be treated early on to prevent this radiographic damage,” she said.

Looking ahead, there need to be more translational studies looking for answers as to why there are phenotypic differences between men and women, as well as why men have spinal fusion more often than women. Bed-to-the-bench studies are warranted to get more answers, she said.

The study was supported by an NIH Centers for Translational Science Award grant. The researchers declared having no conflicts of interest related to the study. One author is supported by the National Institute of Arthritis and Musculoskeletal and Skin Diseases Intramural Research Program, and another by the Spondyloarthritis Association of America and the University of Texas Health Center for Clinical and Translational Sciences KL2 program. Another author is an adviser for AbbVie, Eli Lilly, Gilead, Janssen, MoonLake, Novartis, Pfizer, and UCB, and has grant support from Novartis, Pfizer, and UCB.

Dr. Magrey disclosed being a consultant for Novartis, UCB, Pfizer, AbbVie, Janssen, Bristol-Myers Squibb, and Eli Lilly.

Researchers agree that spinal structural damage is a predictor of further damage in patients with radiographic AS, Marina Magrey, MD, the Roland W. Moskowitz Professor in Rheumatic Diseases at Case Western Reserve University, Cleveland, said in an interview. She pointed out that previous literature has shown that longer disease durations make it more likely that patients will have syndesmophytes.

Previous research has also shown that there was an association between structural damage in the SI joints and the function and mobility of the spine. This observation was independent of the disease activity and prior structural damage in the spine, Dr. Magrey noted.

“This is a very complex disease with very diverse manifestations. Traditionally, it was thought to be a disease of men, but now we believe it is equally common between men and women. The burden is equal between men and women, and they need to be treated equally. Both of them need to be treated early on to prevent this radiographic damage,” she said.

Looking ahead, there need to be more translational studies looking for answers as to why there are phenotypic differences between men and women, as well as why men have spinal fusion more often than women. Bed-to-the-bench studies are warranted to get more answers, she said.

The study was supported by an NIH Centers for Translational Science Award grant. The researchers declared having no conflicts of interest related to the study.

Syndesmophytes are not present in a subgroup of patients with ankylosing spondylitis (AS) and sacroiliac (SI) joint fusion who have had the disease for 20 years or longer, according to findings from a nested case-control study.

Syndesmophytes did not occur in only 23 (7%) of 354 patients, and these patients without spinal-fusing bone growths were less likely to be female but very likely to be HLA-B27 positive, Lauren K. Ridley, MD, a rheumatologist at the University of Texas Health Science Center at Houston, and colleagues reported in The Journal of Rheumatology.

“Women appear to have a different phenotype in AS; we found that they are less likely to form syndesmophytes despite fused SI joints with at least 20 years of disease duration. We do not understand the reasons behind these differences among the possibilities of genetic, hormonal, and bio-mechanical factors,” the authors wrote.

AS is a heterogenous disease that affects different people in various ways, Dr. Ridley noted. “Prior research has shown that and hasn’t really elucidated how different people manifest their disease. Previous research has shown that women tend to have more nonradiographic spondylitis,” Dr. Ridley said in an interview.

“This is still a very heterogenous disease. We don’t fully understand it, and we don’t know why some patients present with SI joint disease [and] no syndesmophytes, or some patients have the opposite. Truly, we do need to do more studies to find out why some patients behave differently and if there are ways we can try to alter that,” Dr. Ridley continued.

The researchers evaluated 354 patients from the Prospective Study of Outcomes in Ankylosing Spondylitis (PSOAS). Of these patients, 23 did not have syndesmophytes. Patients were selected if they had fused SI joints (bilateral grade 4 sacroiliac joint disease) and had a disease course lasting 20 years or more. The researchers identified risk factors for syndesmophytes using classification and regression trees (CART) analysis and then reassessed their validity with univariable logistic regression models.

All 23 patients who had no syndesmophytes were HLA-B27 positive, and all patients older than 45 years at symptom onset had syndesmophytes.

The results also highlighted age of disease onset as an important predictor of syndesmophytes in males. Syndesmophytes were less likely to be reported in males with a disease onset at 16 years or younger.

The presence of syndesmophytes was linked with an age older than 16 years at symptom onset (OR, 2.72; 95% confidence interval, 1.15-6.45), and syndesmophytes were less likely to occur among HLA-B27 positive individuals (P = .03).

Females were less likely than males to have syndesmophytes, as verified by univariable analysis (odds ratio, 0.17; 95% confidence interval, 0.07-0.41).

“There is likely a complex interplay of factors leading to differences in radiographic damage between the sacroiliac joints and the spine in AS, and it is interesting to consider if HLA-B27 may have more effect on sacroiliac joint damage than spinal damage,” the authors noted.

Some limitations of the study include the researchers’ choice to compare a subtype with overt spinal involvement and a subtype with limited spinal involvement when other criteria could have been used to separate cases, and their use of the modified Stoke Ankylosing Spondylitis Scoring System (mSaSSS) to examine radiographic changes over time, as the mSaSSS does not take into account radiographic variation in the zygaphophyseal joints and thoracic spine (and were not part of the dataset). Another limitation was the relatively small cohort size, the researchers noted.

“This was a small study, and further studies are needed to elucidate why AS disease may behave differently in this and other subgroups,” Dr. Ridley and colleagues concluded.

People with immune-mediated inflammatory diseases who are taking immunosuppressants don’t mount as strong of an immune defense against the Omicron variant as they did against the original SARS-CoV-2 wild-type virus, according to two studies published in Annals of the Rheumatic Diseases. One of the studies further showed that vaccinated individuals taking immunosuppressants have poorer cross-neutralizing responses to Omicron than do healthy vaccinated individuals, even after three doses of the COVID-19 mRNA vaccines.

“We carefully suggest that if Omicron-specific vaccination can be administered, it may be an effective way to reduce the risk of breakthrough infections in patients with autoimmune rheumatic disease,” Sang Tae Choi, MD, PhD, of the University College of Medicine, Seoul, Korea, and one of the authors of the study on cross-neutralizing protection, told this news organization. “However, further research is needed on Omicron-specific vaccine effectiveness in patients with immune dysfunctions. We believe that these study results can be of great benefit in determining the strategy of vaccination in the future.”

The earlier study, published in July, examined the ability of COVID-19 vaccines to induce cross-reactive antibody responses against Omicron infections in patients with autoimmune rheumatic diseases (ARDs). The observational study involved 149 patients with ARDs and 94 health care workers as controls, all of whom provided blood samples a median 15 weeks after their second COVID vaccine dose or a median 8 weeks after their third dose. A little more than two-thirds of the patients (68.5%) had received a third mRNA vaccine dose. None of the participants previously had COVID-19.

The researchers compared the rate of breakthrough infections with the Omicron variant to the neutralizing responses in patients’ blood, specifically the cross-neutralizing antibody responses because the original mRNA vaccines targeted a different variant than Omicron. Breakthrough infections were assessed by survey questions.

“Our findings suggested that neither primary series vaccinations nor booster doses are sufficient to induce Omicron-neutralizing responses above the threshold in patients with ARDs, although responses were noticeably increased following the third dose of an mRNA vaccine,” write Woo-Joong Kim, of the Chung-Ang University College of Medicine, Seoul, Korea, and his colleagues. “This impairment of cross-neutralization responses across most of our patients contrasts starkly with a potent elicitation of the Omicron-neutralizing responses after the third vaccination in healthy recipients.”

The average neutralizing responses against the original SARS-CoV-2 strain were similar in both groups: 76% in patients with ARDs and 72% in health care workers after the second dose. The mean response after a third dose was 97% in health care workers and 88% in patients.

The average cross-neutralizing response against the Omicron variant was far lower, particularly in those with rheumatic disease: only 11.5%, which rose to 27% after the third dose. Only 39% of the patient sera showed neutralization of Omicron, even after the third dose. Meanwhile, the mean cross-neutralizing response in health care workers was 18% after the second dose and 50% after the third.

When the researchers compared seropositivity rates against the original virus to neutralizing responses against Omicron, the association between these was stronger in health care workers than in those with ARDs. In fact, among patients with ARDs who seroconverted, only 41% showed any response against Omicron. Among all the patients, most of those who didn’t respond to Omicron (93.5%) had initially seroconverted.

The researchers also looked at the ability to neutralize Omicron on the basis of disease in those who received three doses of the vaccine. About half of those with lupus (52%) showed any neutralization against Omicron, compared with 25% of those with rheumatoid arthritis, 37.5% of those with ankylosing spondylitis, 33% of those with Behçet snydrome, and all of those with adult-onset Still’s disease.

The rate of breakthrough infections was lower in patients (19%) than in health care workers (33%). A similar pattern was seen in the more recent study published Sept. 5. Researchers used data from a prospective cohort study in the Netherlands to examine incidence and severity of Omicron breakthrough infections in patients with immune-mediated inflammatory diseases. The researchers compared infection rates and severity among 1,593 vaccinated patients with inflammatory disease who were taking immunosuppressants and 579 vaccinated controls (418 patients with inflammatory disease not on immunosuppressants and 161 healthy controls).

One in five patients with inflammatory disease (21%) were taking immunosuppressants that substantially impair antibodies, such as anti-CD20 therapy, S1P modulators, or mycophenolate mofetil combination therapy, and 48% of these patients seroconverted after primary vaccination, compared with 96% of patients taking other immunosuppressants and 98% of controls.

Breakthrough infection rates were similar between the control group (31%) and those taking immunosuppressants (30%). Only three participants had severe disease requiring hospitalization: one control and two patients taking immunosuppressants.

“In both studies, the controls had similar or higher rates of breakthrough infections, compared with the immunosuppressed,” noted Alfred Kim, MD, an assistant professor of medicine at Washington University, St Louis, but he added, “one has to consider differences in mitigation strategies, such as masking, that may explain these findings.” That is, patients taking immunosuppressants may be taking fewer risks in the community or have fewer potential exposures, especially in the Korean study, wherein the controls were health care workers.

A greater disparity in infections occurred when considering seroconversion rates. Breakthrough incidence was 38% among those taking immunosuppressants who did not seroconvert, compared with 29% among those who did. A similar trend was seen in breakthrough incidence between those taking strongly antibody-impairing immunosuppressants (36% breakthrough rate) and those taking other immunosuppressants (28%).
