DUBLIN – Patients with psoriatic disease (PsD) face an elevated risk for depression and suicidality that stems from both pathologic inflammatory factors associated with the disease as well as societal stigma, warranting routine screening and having community contacts for mental health professional referrals, Elizabeth Wallace, MD, said at the annual meeting of the Group for Research and Assessment of Psoriasis and Psoriatic Arthritis.

Dr. Wallace, of Cherry Hills Dermatology, Englewood, Colo., discussed the complex interactions between mental illness and psoriatic disease and the potential pitfalls of this comorbidity for these patients.

The topic of mental health is “consistently at the top of our patients’ minds, and certainly our minds too,” said session comoderator and GRAPPA president-elect Joseph F. Merola, MD, MMSc.

“In the U.S., around 17% of people with psoriasis have depression vs. 9% in those without psoriasis,” Dr. Wallace explained. “Psoriasis patients are twice as likely to have depression, compared to those without psoriasis, and psoriasis patients are 33% more likely to attempt suicide and 20% more likely to complete suicide, compared to those without psoriasis.” More severe psoriasis and younger age of onset are also associated with a greater likelihood of suicidality, she added.
 

Mediators of depression

“The inflammatory mechanisms driving PsD can drive depression and anxiety, and vice-versa,” she said. “There are often also genetic links, for example genetic variations in serotonin receptors, and psychological issues in psoriatic disease are predictably worsened by feelings of stigmatization, embarrassment, and social isolation.”

There are also efforts underway in clinics to “normalize” screening for anxiety and depression among this patient cohort, Dr. Wallace said. “We know that our psoriasis patients face social stigma from the visibility of their disease, and that stress can lead to flares of their condition,” she told the attendees. “We also know that patients who experience stigma also have an increased risk of depressive symptoms. We all know now that psoriasis has well-established pathways with upregulated proinflammatory cytokines.

“Increased cytokines stimulate indoleamine 2,3-dioxygenase, which converts tryptophan to kynurenine. Kynurenine is metabolized to quinolinic acid, which is neurotoxic.” She explained that because serotonin derives from tryptophan, decreases in tryptophan lead to reduced serotonin, and therefore increased risk of depression.

Interleukin-6 is known to be upregulated in depression and downregulated with the use of antidepressant medications, Dr. Wallace said. Mouse models in research have shown that deletion of the IL-6 gene produces antidepressant effects, and studies in humans have shown that IL-6, more than any other serum cytokine, is found at higher levels in humans with depression and psoriatic disease.

IL-17 is also implicated in psoriatic disease and mental health problems, Dr. Wallace said. “With stress, you get upregulation of the Tc17 cells, which produce IL-17,” she explained. “IL-17, along with other inflammatory markers, can actually make the blood-brain barrier more permeable, and when you get more permeability to the blood-brain barrier, you get these cytokines that can cross from the periphery and into the brain.

“With this crossing into the brain, you get further activation of more Th17 [cells] and that, on neurons, leads to increased potassium production, which is directly neurotoxic, so you get neuron destruction.”
 

Talking about depression

“So, what can we share with our patients?” Dr. Wallace asked. “We can discuss with them that psoriatic patients in general are more likely to be depressed or to have higher rates of suicide. The literature consistently shows that patients whose psoriasis is successfully treated experience reduced depression, and we can provide an understandable review of systemic medications, with warnings on depression and/or suicidality.”

Dr. Wallace advised to screen for depression with the Patient Health Questionnaire-2 (PHQ-2), a validated, two-item tool that asks, “Over the past 2 weeks, how often have you been bothered by having little interest or pleasure in doing things?” and “Over the past 2 weeks, how often have you been bothered by feeling down, depressed, or hopeless?”

She presented a case study illustrative of the type of presentation she sees in her clinic. It involved a 32-year-old man with plaque psoriasis and a high degree of body surface affected. “It’s now July in Colorado, it’s getting warm, people want to wear their shorts and T-shirts, but he said he could no longer hide his psoriasis,” said Dr. Wallace. “Further, it’s in areas that he cannot hide, such as his scalp, his beard, and he also has nail disease. Often, these patients don’t want to shake hands with their bosses or their colleagues and that’s very embarrassing for them.”

Dr. Wallace explained that this patient had seen advertisements for biologic drugs and requested to commence a treatment course. “During the exam, and now that you are developing some rapport with him, you discover that he is feeling down, is embarrassed at work, and has started to avoid social situations.” This is illustrative of a patient who should be screened for mental health conditions, specifically using PHQ-2, she said.

“You can be the person at the front line to screen these patients for mental health conditions, and, specifically for depression, with PHQ-2,” she said. PHQ-2 scores range from 0 to 6, and a score of 3 or higher is considered a positive screen.

“This is where your relationship with another health provider who is most qualified to care for these patients and validate them for their mental health condition can be absolutely critical,” Dr. Wallace said.

Successful PsD treatment lessens the risk for mental health comorbidities, and this is also seen in psoriatic arthritis, Dr. Wallace pointed out. Patient education is critical regarding their increased risk for depression and potential suicidal ideation, she added.

“It’s our job as clinicians to provide patients with an understandable, easy-to-digest review of systemic medications and warnings on depression and suicidality so that they can be aware of these factors.”

Perspective from Dr. Merola

In an interview, Dr. Merola, a double board-certified dermatologist and rheumatologist at Brigham and Women’s Hospital, Boston, discussed the interactions between mental and physical illness.

“One of the things we are learning is that it’s very much a multifactorial issue, in that skin and joints contribute, in some obvious ways, to anxiety and depression, like the fact that somebody doesn’t feel good about their appearance, or they can’t complete daily activities,” he said. “Those are the more obvious ones. But there is data and evidence that there is a biology behind that as well – inflammatory cytokines that drive skin disease probably also have a direct impact on the CNS and probably also drive anxiety and depression.

“We know that disordered sleep contributes to anxiety – think about how we feel if we get a horrible night’s sleep ... it’s hard to pick apart: ‘Am I depressed, am I anxious because I am having too much coffee? Because I am fatigued?’ So, we get into these circles, but the point is, we have to break these cycles, and we have to do it in multiple places. Yes, we have to fix the skin and the joints, but we also have to have interventions and think about how to screen for anxiety and depression. We also have to think about identifying disordered sleep, and how we intervene there as well.”

These challenges require a collaborative approach among physicians. “We can help patients to build their team that gets them help for their skin, for their joints, for their anxiety or depression, their disordered sleep, for their nutritional disorders, their obesity, and so on. So, we are trying to pick apart and unpack those complexities,” he said.

In regard to the potential impacts of this holistic strategy on physician workloads, Dr. Merola acknowledged it is important to consider physician wellness. “There’s no question that we want to be doing the best we can for our colleagues, but we don’t want to overload our colleagues by saying, ‘By the way, not only should we be treating their skin and joints,’ which of course we should be doing, but ‘could you also manage their diabetes, their obesity, their disordered sleep, their anxiety, their depression, difficulties with insurance, getting access to treatments, etc.’ 

“This is where effective collaboration between physicians becomes important,” he stressed. “We can’t manage every single piece, but we can make sure our patients are informed, are aware, and assist them to get the help that they need.”

In the United States, there “is a real issue” with access to mental health care and greater awareness needs to be created around this issue, he added.

Dr. Wallace and Dr. Merola report no relevant financial relationships.

People who experience chronic pain and tiredness from fibromyalgia have an increased risk for all-cause mortality, a new analysis of evidence says.

The condition can lead people to be vulnerable to accidents, infections, and even suicide, according to the report published in RMD Open.

The researchers suggest that care providers monitor physical and mental health to lower the dangers.

People with fibromyalgia often have other health issues, including rheumatic, gut, neurological, and mental health disorders, according to The BMJ. More and more people are being diagnosed with fibromyalgia. The cause of the illness remains unclear.

The researchers looked at eight studies published between 1999 and 2020 and pooled results from six of them. The studies involved a total of 188,000 adults.

The analysis of the data revealed that fibromyalgia was linked to a 27% greater risk of death from all causes.

Those with fibromyalgia were at a 44% greater risk of infections, including pneumonia. Their suicide risk was more than three times higher.

The greater risk of all-cause death could result from fatigue, poor sleep, and concentration problems, The BMJ said.

The patients had a 12% lower risk of dying from cancer, the analysis found. This could be because they tend to make more visits to health care professionals, the authors suggest.

“Fibromyalgia is often called an ‘imaginary condition,’ with ongoing debates on the legitimacy and clinical usefulness of this diagnosis. Our review provides further proof that fibromyalgia patients should be taken seriously, with particular focus on screening for suicidal ideation, prevention of accidents, and prevention and treatment of infections,” the researchers say.

TOPLINE:

In patients with rheumatoid arthritis, the presence of antidrug antibodies was associated with a diminished response to biologic disease-modifying antirheumatic drugs in a prospective cohort study.

METHODOLOGY:

• Researchers prospectively analyzed data from 230 patients (mean age, 54.3 years; 77.0% women) with RA diagnosis recruited from March 3, 2014, to June 21, 2016.
• All were initiating new treatment with an anti–tumor necrosis factor (TNF) monoclonal antibody (mAb; either infliximab or adalimumab), etanercept, tocilizumab, or rituximab, according to the choice of the treating physician.
• The primary outcome was the association of antidrug antibody positivity with European Alliance of Associations for Rheumatology (EULAR) response to treatment at month 12, assessed through univariate logistic regression.

TAKEAWAY:

• At month 12, antidrug antibody positivity was 38.2% in patients who were treated with anti-TNF mAbs, 6.1% with etanercept, 50.0% with rituximab, and 20.0% with tocilizumab.
• There was an inverse association between antidrug antibody positivity directed against all biologic drugs and EULAR response at month 12 (odds ratio, 0.19; 95% confidence interval, 0.09-0.38; P < .001).
• In the multivariable analysis, antidrug antibodies, body mass index, and rheumatoid factor were independently and inversely associated with response to treatment.
• There was a significantly higher drug concentration of anti-TNF mAbs in patients with antidrug antibody–negative vs. antidrug antibody–positive status (mean difference, –9.6 mg/L; 95% CI, –12.4 to –6.9; P < .001).

IN PRACTICE:

Findings of this study suggest that antidrug antibodies are associated with nonresponse to biologic drugs and can be monitored in the management of patients with RA, particularly nonresponders.

SOURCE:

Samuel Bitouin, MD, PhD, of the rheumatology department at Paris-Saclay University, and coauthors in the ABIRISK (Anti-Biopharmaceutical Immunization: Prediction and Analysis of Clinical Relevance to Minimize the Risk) consortium reported the study in JAMA Network Open. The work was funded by a grant from the European Union Innovative Medicines Initiative.

LIMITATIONS:

Though the study demonstrated an association when all biologic drugs were analyzed together, it was not powered to demonstrate an association for each drug class.

DISCLOSURES:

Many authors reported financial relationships with pharmaceutical companies.

TOPLINE:

In patients with rheumatoid arthritis, the presence of antidrug antibodies was associated with a diminished response to biologic disease-modifying antirheumatic drugs in a prospective cohort study.

METHODOLOGY:

• Researchers prospectively analyzed data from 230 patients (mean age, 54.3 years; 77.0% women) with RA diagnosis recruited from March 3, 2014, to June 21, 2016.
• All were initiating new treatment with an anti–tumor necrosis factor (TNF) monoclonal antibody (mAb; either infliximab or adalimumab), etanercept, tocilizumab, or rituximab, according to the choice of the treating physician.
• The primary outcome was the association of antidrug antibody positivity with European Alliance of Associations for Rheumatology (EULAR) response to treatment at month 12, assessed through univariate logistic regression.

TAKEAWAY:

• At month 12, antidrug antibody positivity was 38.2% in patients who were treated with anti-TNF mAbs, 6.1% with etanercept, 50.0% with rituximab, and 20.0% with tocilizumab.
• There was an inverse association between antidrug antibody positivity directed against all biologic drugs and EULAR response at month 12 (odds ratio, 0.19; 95% confidence interval, 0.09-0.38; P < .001).
• In the multivariable analysis, antidrug antibodies, body mass index, and rheumatoid factor were independently and inversely associated with response to treatment.
• There was a significantly higher drug concentration of anti-TNF mAbs in patients with antidrug antibody–negative vs. antidrug antibody–positive status (mean difference, –9.6 mg/L; 95% CI, –12.4 to –6.9; P < .001).

IN PRACTICE:

Findings of this study suggest that antidrug antibodies are associated with nonresponse to biologic drugs and can be monitored in the management of patients with RA, particularly nonresponders.

Flares of systemic lupus erythematosus (SLE), particularly those involving severe kidney disease, were associated with growth spikes of the gut bacteria Ruminococcus blautia gnavus in a small, 4-year observational study that also demonstrated an underlying, inherent instability in the gut microbiome of patients with SLE.

Of 16 patients with SLE studied during the provision of routine care and monitoring, 5 had R. gnavus blooms that were “strikingly concordant with periods of raised disease activity,” Gregg J. Silverman, MD, of NYU Grossman School of Medicine, New York, and coinvestigators reported in Annals of the Rheumatic Diseases.

Four of the five patients with flare-associated R. gnavus blooms had lupus nephritis (LN); the other had a flare involving inflammation in multiple joints. The four patients with concurrent LN and spikes in R. gnavus also represented almost half of patients who had LN disease flares (four of nine) during the study period. The nine patients in the study with renal involvement, and the four with concurrent R. gnavus spikes and flares, represented different races and ethnicities.

The findings build upon research published by the NYU group several years ago showing that patients with SLE had more R. gnavus in the gut than similar patients without the disease, and that flares closely tracked major increases in R. gnavus growth. Evidence of R. gnavus expansions in patients with SLE now comes from several cohorts in the United States as well as cohorts in Europe and China, the researchers noted in their new paper.
 

An underlying, unstable microbiome

The new study at NYU took a “deeper dive” than previous research, looking at individuals over a longer period of time, Dr. Silverman, the study’s senior investigator and associate director of rheumatology at NYU Langone Health, said in an interview. Blood and a total of 44 stool samples from the 16 patients were analyzed, as were a total of 72 stool samples from 22 healthy control volunteers.

Importantly, he said, the gut microbiome in patients with SLE was found to be inherently unstable over time, compared with the microbiota communities of the controls. “There was an instability, a shifting dynamic composition of the microbiome [in patients with lupus]. ... Healthy individuals had more of a balance, with small changes over time” and a stable, low abundance of R. gnavus, Dr. Silverman said.

Transient expansions of several pathogenic species occurred in some of the patients with lupus (and not in controls), but blooms of R. gnavus were the most common. The researchers said in their paper that they “speculate that susceptibility for specific clinical features during R. gnavus blooms reflect in part differences in genetic susceptibility of the patient.”

Patients on cytotoxic agents or antibiotics were excluded from the study, but the study was not designed to disentangle the potential influence of diet or prior antibiotic exposure, they noted. Larger studies are needed that are better controlled and that include more frequent assessments, Dr. Silverman added.
 

A sure association and probable cause

“There seems to be a special connection [of R. gnavus] to lupus nephritis, which is an important, major subset of disease,” said Martin Kriegel, MD, PhD, chief or rheumatology and clinical immunology at the University of Munster (Germany). Dr. Kriegel also researches the gut microbiome in lupus and was asked to comment on the new findings from NYU.

The “difficult question is, is the bug driving the flare [as the NYU paper proposes], or is it the lupus nephritis that leads to overgrowth?” he said, noting that it “is well known that kidney disease, whether from lupus or other causes, creates disturbances in the microbiome.”

It’s “likely the case” that the pathobiome – with R. gnavus being an important pathobiont – helps to drive flares, he said. The new research shows only an association, but studies done in mice – including prior research by Dr. Silverman – support a mechanistic link, said Dr. Kriegel, also adjunct associate professor of immunobiology and of medicine at Yale University, New Haven, Conn.

Investigators in the microbiome space are moving toward more strain-level analysis – “not only measuring what organisms are there, but culturing them and sequencing them,” Dr. Kriegel noted, and the new study does just this.

The R. gnavus strains isolated during lupus flares were distinguishable from strains found in healthy people – and from strains found by other researchers in patients with inflammatory bowel disease – by their common expression of a novel type of cell membrane–associated lipoglycan. The lipoglycans were recognized by specific serum IgG2 antibodies that were detected concurrently with R. gnavus blooms and lupus flares, Dr. Silverman and his colleagues reported.

Dr. Silverman and Dr. Kriegel both study the paradigm of a gut-barrier breach, whereby pathogenic bacteria cause intestinal permeability, allowing bacterial leakages that trigger inflammation and immune responses. “We think that in lupus and other rheumatic diseases like rheumatoid arthritis, a leaky gut barrier is an important mechanism, even though these patients don’t have gastrointestinal symptoms,” said Dr. Kriegel, who has studied the role of another potentially pathogenic bacteria, Enterococcus gallinarum, in SLE.

Strengthening the gut barrier may be a plausible, general approach to reducing the severity of diseases like SLE and RA until more personalized approaches targeting individuals’ microbiome are developed, he noted.

Future treatments involving antibacterial agents, probiotics or dietary regimens that prevent imbalances in the gut microbiome would be “benign,” compared with currently utilized immunosuppressive medications, Dr. Silverman said.

The NYU study was funded in part by grants from the National Institutes of Health and the Lupus Research Alliance. Dr. Silverman disclosed that NYU has filed a patent application for an antibody test to detect serum antibodies to the lipoglycan made by some strains of R. gnavus. Dr. Kriegel disclosed that he holds a patent at Yale related to the Enterococcus bacteria he studies, and that he consults for Roche, Enterome, and Eligo Biosciences.

The effectiveness and safety of biosimilars for psoriasis appear to be similar to the originator biologics, reported the authors of a review of studies comparing the two.

“This systematic review found that there was no clinically or statistically significant difference in the efficacy and safety between biosimilars and originators of adalimumab, etanercept, infliximab, and ustekinumab for the treatment of psoriasis,” senior study author and clinical lecturer Zenas Z. N. Yiu, MBChB, PhD, and his colleagues at the University of Manchester, England, wrote in JAMA Dermatology.“The biosimilars evaluated in this study could be considered alongside originators for biologic-naive patients to improve the accessibility of biological treatments,” they added. “Switching patients currently on originators to biosimilars could be considered where clinically appropriate to reduce treatment costs.”

Biologics versus biosimilars

In contrast to most chemically synthesized drugs, biologics are created from living organisms, and they have complex structures that can vary slightly from batch to batch, Luigi Naldi, MD, director of the department of dermatology of Ospedale San Bortolo, Vicenza, Italy, and Antonio Addis, PharmD, researcher in the department of epidemiology, Regione Lazio, in Rome, wrote in an accompanying editorial.

Once the patent on the “originator” biologic expires, U.S. and European regulators allow other manufacturers to develop similar molecules – biosimilars – through an abbreviated approval process. If the results of a limited number of equivalence or noninferiority clinical trials are acceptable, registration for all the indications of the originator is allowed for its biosimilars. Referring to the expense of biologics, Dr. Naldi and Dr. Addis noted that in the United States, “biologics comprise less than 3% of the volume of drugs on the market, but account for more than one-third of all drug spending.”

Systematic review

Dr. Yiu and his colleagues queried standard medical research databases in August 2022, and included 14 randomized clinical trials (10 adalimumab, 2 etanercept, 1 infliximab, and 1 ustekinumab) and 3 cohort studies (1 adalimumab, 1 etanercept, 1 infliximab and etanercept) in their review.

Twelve trials compared biosimilars vs. originators in originator-naive patients, and 11 trials compared switching from originators to biosimilars vs. continuous treatment with the originator.

The researchers found the following:

At week 16, mean PASI75 (Psoriasis Area and Severity Index) response rates ranges from 60.7% to 90.6% for adalimumab biosimilars, vs. 61.5% to 91.7% for the originator. Mean PASI75 responses for the two etanercept biosimilars were 56.1% and 76.7% vs. 55.5% and 73.4% for the originator. In the ustekinumab study, mean PASI75 responses were 86.1% for the biosimilar vs. 84.0% for the originator.

At week 52, mean PASI75 responses were between 86.3% and 92.8% for adalimumab biosimilars vs. 84.9% and 93.9% for the originator. In the one comparison of an etanercept biosimilar, mean PAS175 responses were 80.9% for the biosimilar vs. 82.9% for the originator.

In studies involving patients switching from the originator to a biosimilar vs. continuing treatment with the originator, 32-week response rates ranged from 87.0% to 91.3% for adalimumab biosimilars and from 88.2% to 93.2% for the originator. In the one ustekinumab study, the 32-week mean PASI75 response was 92.6% after switching from the originator to a biosimilar vs. 92.9% with continuous treatment with the originator.

At week 52, mean PASI75 responses to adalimumab were between 84.2% and 94.8% for patients who switched to biosimilars and between 88.1% and 93.9% for those who stayed on the originator.

At week 52, in all the randomized trials, the incidence of adverse events and serious adverse events among those who switched to the biosimilar and those who continued with the originator were similar. Two cohort studies showed similar safety outcomes between originators and biosimilars, but one reported more adverse events in patients who switched to adalimumab biosimilars (P = .04).

Three clinical trials showed low risk for bias, 11 had moderate risk, and all cohort studies had moderate to high risk for bias.

Experts weigh in

Asked to comment on the study, Steven R. Feldman, MD, PhD, professor of dermatology at Wake Forest University, Winston-Salem, N.C., told this news organization that he expects that the results will affect patient care.

However, he added, “I believe the decision of whether to use a biosimilar instead of the originator biologic may be more in the hands of the insurers than in the hands of physicians and patients.

“Biologics for psoriasis are so complicated that even the originator products vary from batch to batch. A biosimilar is basically like another batch of the innovative product,” explained Dr. Feldman, who was not involved in the study. “If we’re comfortable with patients being on different batches of the innovator product, we probably should be comfortable with them being on a biosimilar, as we have more evidence for the similarity of the biosimilar than we do for the current batch of the originator product.”

Aída Lugo-Somolinos, MD, professor of dermatology and director of the Contact Dermatitis Clinic at the University of North Carolina, Chapel Hill, said that “biologics have become the treatment of choice for moderate to severe psoriasis, and the use of biosimilars may be an alternative to reduce psoriasis treatment costs.

“Unfortunately, this study included a comparison of the existing biosimilars, which are drugs that are not the first line of treatment for psoriasis any longer,” added Dr. Lugo-Somolinos, who was not involved in the study.

Neil J. Korman, MD, PhD, professor of dermatology and codirector of the Skin Study Center at Case Western Reserve University, Cleveland, said the study was an important systematic review.

“This is a very timely publication because in the United States, several biosimilars are reaching the market in 2023,” he said. “The costs of the originator biologics are extraordinarily high, and the promise of biosimilars is that their costs will be significantly lower.”

Because all the studies were short term, Dr. Korman, who was not involved in the study, joins the study authors in recommending further related research into the long-term safety and efficacy of these agents.

Dr. Feldman, as well as one study author and one editorial author, reported relevant relationships with various pharmaceutical companies, including those that develop biosimilars. The remaining study authors, as well as Dr. Lugo-Somolinos and Dr. Korman, reported no relevant relationships. The study was funded by the Psoriasis Association and supported by the NIHR (National Institute for Health and Care Research) Manchester Biomedical Research Centre.

Yiu, MBChB, PhD, and his colleagues at the University of Manchester, England, wrote in JAMA Dermatology.“The biosimilars evaluated in this study could be considered alongside originators for biologic-naive patients to improve the accessibility of biological treatments,” they added. “Switching patients currently on originators to biosimilars could be considered where clinically appropriate to reduce treatment costs.”

Biologics versus biosimilars

In contrast to most chemically synthesized drugs, biologics are created from living organisms, and they have complex structures that can vary slightly from batch to batch, Luigi Naldi, MD, director of the department of dermatology of Ospedale San Bortolo, Vicenza, Italy, and Antonio Addis, PharmD, researcher in the department of epidemiology, Regione Lazio, in Rome, wrote in an accompanying editorial.

Once the patent on the “originator” biologic expires, U.S. and European regulators allow other manufacturers to develop similar molecules – biosimilars – through an abbreviated approval process. If the results of a limited number of equivalence or noninferiority clinical trials are acceptable, registration for all the indications of the originator is allowed for its biosimilars. Referring to the expense of biologics, Dr. Naldi and Dr. Addis noted that in the United States, “biologics comprise less than 3% of the volume of drugs on the market, but account for more than one-third of all drug spending.”

Systematic review

Dr. Yiu and his colleagues queried standard medical research databases in August 2022, and included 14 randomized clinical trials (10 adalimumab, 2 etanercept, 1 infliximab, and 1 ustekinumab) and 3 cohort studies (1 adalimumab, 1 etanercept, 1 infliximab and etanercept) in their review.

Twelve trials compared biosimilars vs. originators in originator-naive patients, and 11 trials compared switching from originators to biosimilars vs. continuous treatment with the originator.

The researchers found the following:

At week 16, mean PASI75 (Psoriasis Area and Severity Index) response rates ranges from 60.7% to 90.6% for adalimumab biosimilars, vs. 61.5% to 91.7% for the originator. Mean PASI75 responses for the two etanercept biosimilars were 56.1% and 76.7% vs. 55.5% and 73.4% for the originator. In the ustekinumab study, mean PASI75 responses were 86.1% for the biosimilar vs. 84.0% for the originator.

At week 52, mean PASI75 responses were between 86.3% and 92.8% for adalimumab biosimilars vs. 84.9% and 93.9% for the originator. In the one comparison of an etanercept biosimilar, mean PAS175 responses were 80.9% for the biosimilar vs. 82.9% for the originator.

In studies involving patients switching from the originator to a biosimilar vs. continuing treatment with the originator, 32-week response rates ranged from 87.0% to 91.3% for adalimumab biosimilars and from 88.2% to 93.2% for the originator. In the one ustekinumab study, the 32-week mean PASI75 response was 92.6% after switching from the originator to a biosimilar vs. 92.9% with continuous treatment with the originator.

At week 52, mean PASI75 responses to adalimumab were between 84.2% and 94.8% for patients who switched to biosimilars and between 88.1% and 93.9% for those who stayed on the originator.

At week 52, in all the randomized trials, the incidence of adverse events and serious adverse events among those who switched to the biosimilar and those who continued with the originator were similar. Two cohort studies showed similar safety outcomes between originators and biosimilars, but one reported more adverse events in patients who switched to adalimumab biosimilars (P = .04).

Three clinical trials showed low risk for bias, 11 had moderate risk, and all cohort studies had moderate to high risk for bias.

Experts weigh in

Asked to comment on the study, Steven R. Feldman, MD, PhD, professor of dermatology at Wake Forest University, Winston-Salem, N.C., told this news organization that he expects that the results will affect patient care.

However, he added, “I believe the decision of whether to use a biosimilar instead of the originator biologic may be more in the hands of the insurers than in the hands of physicians and patients.

“Biologics for psoriasis are so complicated that even the originator products vary from batch to batch. A biosimilar is basically like another batch of the innovative product,” explained Dr. Feldman, who was not involved in the study. “If we’re comfortable with patients being on different batches of the innovator product, we probably should be comfortable with them being on a biosimilar, as we have more evidence for the similarity of the biosimilar than we do for the current batch of the originator product.”

Aída Lugo-Somolinos, MD, professor of dermatology and director of the Contact Dermatitis Clinic at the University of North Carolina, Chapel Hill, said that “biologics have become the treatment of choice for moderate to severe psoriasis, and the use of biosimilars may be an alternative to reduce psoriasis treatment costs.

“Unfortunately, this study included a comparison of the existing biosimilars, which are drugs that are not the first line of treatment for psoriasis any longer,” added Dr. Lugo-Somolinos, who was not involved in the study.

Neil J. Korman, MD, PhD, professor of dermatology and codirector of the Skin Study Center at Case Western Reserve University, Cleveland, said the study was an important systematic review.

“This is a very timely publication because in the United States, several biosimilars are reaching the market in 2023,” he said. “The costs of the originator biologics are extraordinarily high, and the promise of biosimilars is that their costs will be significantly lower.”

Because all the studies were short term, Dr. Korman, who was not involved in the study, joins the study authors in recommending further related research into the long-term safety and efficacy of these agents.

Dr. Feldman, as well as one study author and one editorial author, reported relevant relationships with various pharmaceutical companies, including those that develop biosimilars. The remaining study authors, as well as Dr. Lugo-Somolinos and Dr. Korman, reported no relevant relationships. The study was funded by the Psoriasis Association and supported by the NIHR (National Institute for Health and Care Research) Manchester Biomedical Research Centre.

The recent Food and Drug Administration approval of colchicine 0.5 mg (Lodoco) for use in atherosclerotic cardiovascular disease (ASCVD) prevention will possibly create opportunities to use the drug to treat residual risk for ASCVD in some patients with immune-mediated inflammatory diseases, particularly in rheumatology.

Potential in rheumatology

The 0.5-mg dose is just a shade under the 0.6-mg, twice daily dosing rheumatologists typically prescribe for gout, Christie Bartels, MD, MS, chief of rheumatology at the University of Wisconsin–Madison, said in an interview. Clinicians also use the 0.6-mg dose off-label for pseudogout or calcium pyrophosphate deposition disease (CPPD), Dr. Bartels noted.

University of Wisconsin

The new formulation opens the consideration for using colchicine more in patients with psoriatic arthritis, lupus, and rheumatoid arthritis, she said. “I think we could certainly discuss it, particularly, in secondary prevention patients who already had an event or who are at the highest risk and already on optimal traditional agents,” she said.

She cited previous comments by Paul Ridker, MD, director of the center for cardiovascular disease prevention at Brigham and Women’s Hospital in Boston, and developer of the high-sensitivity C-reactive protein (hsCRP) test for measuring inflammatory markers. “We might not know the answer because Dr. Ridker pointed out he used colchicine 0.5 mg in patients that had a high-sensitivity CRP that was high; we need patients who have had inflammation of unknown origin, so those patients presumably weren’t already on another anti-inflammatory,” she said, noting that hydroxychloroquine, methotrexate, and some biologics provide some protection from cardiovascular risks.

However, a potential role for long-term colchicine 0.5 mg in ASCVD prevention may cause consideration for changing the drug’s role in gout treatment, Dr. Bartels said. “In gout, where we do have an FDA-approved indication for colchicine, we used to use it only for the first 6 months while we were getting patients to goal on allopurinol, which was usually then monotherapy after the first 6 months,” she said. “I think this will likely change how I treat gout patients in that I may also offer to continue both medications [colchicine and allopurinol] if they are tolerating them well.

“And then in patients where I’m using it off-label in CPPD, I might again share with them that in addition to possibly helping their CPPD, there may be this added benefit to reduce inflammation just in discussing the risks and benefits of the medicine.”

However, rheumatologists must be careful in using colchicine beyond the typical 6-month cycle, Dr. Bartels said. “One of the tricky things with colchicine, and part of the reason we did not traditionally continue it specifically past the first 6 months, was that it can cause myopathies or cytopenias, so we still have to counsel patients regarding these risks and monitor that,” she said.

Additionally, colchicine can have drug interactions with statins or calcium channel blockers that can change colchicine levels. “I think the dose here is so low, the 0.5 mg, that it’s probably still safe, but again, it’s something that we have to take a look at in the patient’s whole picture and the rest of their burden of their meds in order to make a decision with them,” Dr. Bartels said.

Possibilities in dermatology

The LoDoCo2 trial one of two major randomized trials that supported approval of colchicine 0.5 mg, reported that treated patients had a 60% lower rate of gout than the placebo group (1.4% vs. 3.4%). Joel Gelfand, MD, MSCE, the James J. Leyden professor of dermatology and epidemiology at the University of Pennsylvania, Philadelphia, pointed to this in evaluating the dermatologic implications of the drug’s approval. “This may be of particular interest as people with psoriasis have an increased risk of gout,” he said in emailed comments.

Colchicine’s mechanism of action to reduce inflammation parallels that of tumor necrosis factor (TNF) inhibitors used for dermatologic indications, namely by inhibiting leukocyte adhesion to disrupt the downregulation of TNF receptors, Dr. Gelfand said.

“Interestingly, observational data suggests biologics that target TNF such as adalimumab, etanercept, etc., are associated with a reduction in CV events, and in placebo-controlled trials we conducted in psoriasis patients, it reduced key inflammatory mediators of cardiovascular disease, including IL [interleukin]-6,” he said. “Randomized clinical trials to evaluate the ability of TNF inhibitors, which are now available as biosimilars, to prevent cardiovascular events in high-risk patients, should be conducted, and more work is needed to identify which additional immune-targeted treatments may lower CV risk with an acceptable safety profile.”

Colchicine currently has few indications for rare conditions in dermatology, Dr. Gelfand said, including Sweets syndrome, subcorneal pustular dermatosis, and cutaneous vasculitis. “There are some reports to suggest it may help psoriatic disease, but current data are limited and insufficient to recommend its use for psoriasis and/or psoriatic arthritis,” he said.

The approval of colchicine 0.5 mg for ASCVD could be meaningful for people with psoriasis who are also being treated for CV risk factors, Dr. Gelfand said. “Additional considerations such as signs of residual inflammation (elevated hsCRP) and CV imaging findings may be used to further guide shared decision-making for optimal use,” he said.

Another consideration he noted: “This is also a novel 0.5-mg formulation, and thus cost may be an issue.”
 

Would side effects bar use in gastroenterology?

Colchicine 0.5 mg may not move the needle much for expanding treatment of ASCVD in patients with inflammatory bowel disease (IBD) and potentially other gastrointestinal conditions, Edward Loftus Jr., MD, the Maxine and Jack Zarrow Family professor of gastroenterology specifically for IBD at the Mayo Clinic in Rochester, Minn., told MDEdge in emailed comments. “Given the GI side effect profile [of colchicine], I am not sure I would go there,” he said.

Mayo Clinic

“Hopefully, the prescribers of this low-dose formulation are aware of the gastrointestinal side effects, such as diarrhea and nausea, and educate patients about these side effects so that a proper risk-benefit discussion can ensue,” he said.

A European Alliance of Associations for Rheumatology task force has released new guidance on imaging of crystal-induced arthropathies (CiA). The document provides recommendations for using imaging for diagnosis and monitoring of these types of diseases.

“These are the first-ever EULAR recommendations on imaging in this group of diseases. In fact, we are not aware of any similar international recommendations which provide guidance on which imaging technique, when, and how [they] should be used for crystal-induced arthropathies,” lead author Peter Mandl, MD, PhD, of the division of rheumatology at the Medical University of Vienna, told this news organization. Dr. Mandl presented the new recommendations at the annual European Congress of Rheumatology.

While some rheumatologists very familiar with crystal-induced arthropathies already regularly use imaging with these patients, these formal recommendations could highlight to wider audiences that “these imaging modalities can be very sensitive and specific for CiA,” said Sara K. Tedeschi, MD, MPH, assistant professor of medicine at Harvard Medical School and head of crystal-induced arthritis diseases at Brigham and Women’s Hospital in Boston. She was not involved with the work.

The document included general recommendations for imaging in CiA as well as specific recommendations for gout, basic calcium phosphate deposition disease (BCPD), and calcium pyrophosphate deposition disease (CPPD). Across all disease types, performing imaging on symptomatic areas as well as disease-specific target sites should be considered, the recommendations state. This includes the first metatarsophalangeal joint in gout, the wrist and knee in CPPD, and the shoulder in BCPD.

Both ultrasound (US) and dual-energy CT (DECT) are the recommended imaging modalities in gout. If imaging reveals characteristic features of monosodium urate (MSU) crystal deposition, synovial fluid analysis is not necessary to confirm a gout diagnosis. The volume of MSU crystals on imaging can also be used to predict future disease flares.

Showing imaging and explaining imaging findings may help patients understand their condition and adhere to treatment regimens, the recommendations state. “I think it’s a very powerful way to counsel patients,” Dr. Tedeschi said in an interview.

Imaging is necessary in the diagnosis of BCPD, and clinicians should use either conventional radiography or US. These imagining modalities are recommended for CPPD, and clinicians can use CT if they suspect axial involvement. The document does not recommend serial imaging for either BCPD or CPPD unless there has been an “unsuspected change in clinical characteristics.”

These recommendations highlight how imaging can have a “powerful impact on patient counseling and diagnosis,” said Dr. Tedeschi. She emphasized the importance of US training in rheumatology fellowship programs.

During his presentation at EULAR 2023, Dr. Mandl also highlighted a robust research agenda to further investigate how imaging can aid in the diagnosis and treatment of CiA. “It would be great to have an imaging modality someday that would help us differentiate between various types of calcium crystal,” he said.

Dr. Mandl has financial relationships with AbbVie, Bristol-Myers Squibb, Celgene, Eli Lilly, Janssen, Merck Sharp & Dohme, Novartis, Roche, and UCB. Dr. Tedeschi has worked as a consultant for Novartis.

While some rheumatologists very familiar with crystal-induced arthropathies already regularly use imaging with these patients, these formal recommendations could highlight to wider audiences that “these imaging modalities can be very sensitive and specific for CiA,” said Sara K. Tedeschi, MD, MPH, assistant professor of medicine at Harvard Medical School and head of crystal-induced arthritis diseases at Brigham and Women’s Hospital in Boston. She was not involved with the work.

The document included general recommendations for imaging in CiA as well as specific recommendations for gout, basic calcium phosphate deposition disease (BCPD), and calcium pyrophosphate deposition disease (CPPD). Across all disease types, performing imaging on symptomatic areas as well as disease-specific target sites should be considered, the recommendations state. This includes the first metatarsophalangeal joint in gout, the wrist and knee in CPPD, and the shoulder in BCPD.

Both ultrasound (US) and dual-energy CT (DECT) are the recommended imaging modalities in gout. If imaging reveals characteristic features of monosodium urate (MSU) crystal deposition, synovial fluid analysis is not necessary to confirm a gout diagnosis. The volume of MSU crystals on imaging can also be used to predict future disease flares.

Showing imaging and explaining imaging findings may help patients understand their condition and adhere to treatment regimens, the recommendations state. “I think it’s a very powerful way to counsel patients,” Dr. Tedeschi said in an interview.

Imaging is necessary in the diagnosis of BCPD, and clinicians should use either conventional radiography or US. These imagining modalities are recommended for CPPD, and clinicians can use CT if they suspect axial involvement. The document does not recommend serial imaging for either BCPD or CPPD unless there has been an “unsuspected change in clinical characteristics.”

These recommendations highlight how imaging can have a “powerful impact on patient counseling and diagnosis,” said Dr. Tedeschi. She emphasized the importance of US training in rheumatology fellowship programs.

During his presentation at EULAR 2023, Dr. Mandl also highlighted a robust research agenda to further investigate how imaging can aid in the diagnosis and treatment of CiA. “It would be great to have an imaging modality someday that would help us differentiate between various types of calcium crystal,” he said.

Dr. Mandl has financial relationships with AbbVie, Bristol-Myers Squibb, Celgene, Eli Lilly, Janssen, Merck Sharp & Dohme, Novartis, Roche, and UCB. Dr. Tedeschi has worked as a consultant for Novartis.

TOPLINE:

Methotrexate (MTX) is not associated with testicular toxicity, so therapy can be safety started in men pursuing parenthood, a small study finds.

METHODOLOGY:

• Lack of evidence regarding MTX’s effect on sperm quality has resulted in inconsistent recommendations for men actively pursuing parenthood.
• Researchers enrolled 20 men aged 18 years or older with an immune-mediated inflammatory disease (IMID) who were about to begin MTX therapy and 25 healthy men as controls.
• Participants provided semen samples prior to beginning MTX therapy and 13 weeks after beginning therapy.
• Researchers tested samples in both groups for markers of testicular toxicity.
• Also evaluated whether MTX polyglutamates could be detected in sperm of seminal fluid, as a secondary outcome.

TAKEAWAY:

• Found no significant differences in conventional semen parameters, sperm DNA damage, or male reproductive endocrine axis between the MTX group and controls.
• The concentration of MTX polyglutamates is low in both sperm and seminal fluid and is particularly low in sperm.

IN PRACTICE:

“Therapy with MTX can be safely started or continued in men diagnosed with an IMID and with an active wish to become a father,” the authors write.

STUDY DETAILS:

Luis Fernando Perez-Garcia, MD, Erasmus Medical Center, Rotterdam, the Netherlands, led the research. The study was published online in Annals of the Rheumatic Diseases on June 1, 2023.

LIMITATIONS:

The small number of participants and that the study included only MTX starters and not those who have taken MTX longer term.

DISCLOSURES:

Grants from the Dutch Arthritis Foundation, The Netherlands Organization for Health Research and Development, and Consejo Nacional de Ciencia y Tecnologia funded the project. Researchers disclosed financial relationships with Galapagos NV and UCB.

Adalimumab, sold under the brand name Humira, enjoyed a long run as one of the world’s best-selling medicines. But its 20-year, competition-free period has ended, and despite its best efforts to delay their arrival, drug manufacturer AbbVie now faces increasing competition from biosimilars entering the marketplace.
 

But one biosimilar about to be launched may be something of a game changer. Coherus BioSciences has announced plans to market its biosimilar Yusimry (adalimumab-aqvh) at a cost of $995 for two autoinjectors. This represents an approximate 85% discount over Humira’s sale list price of $6922.

This price, however, is slated to plunge even further as Coherus has also revealed that it will work with the Mark Cuban Cost Plus Drug Company (MCCPDC) to offer an even lower price. When Yusimry launches in July, it will sell for about $579 for two autoinjectors, making it the lowest-priced adalimumab biosimilar on the market.

“Coherus and Cost Plus Drug Company share a common mission, to increase access to high-quality medicine for patients at an affordable price,” said Dennis Lanfear, MBA, president, CEO and chairman of Coherus. “Mark Cuban and his team offer innovative solutions to health care problems, and Coherus is also a highly innovative company focused on unmet patient needs.”

He noted that, with adalimumab biosimilar pricing, this translates to a low list price approach. “We are pleased that Yusimry will be a part of that, as the first biologic they carry,” Mr. Lanfear said.

MCCPDC prices are based on the cost of ingredients and manufacturing plus 15% margin, a $3 pharmacy dispensing fee, and a $5 shipping fee. The company has expanded its inventory from 100 generics to more than 350 medications since it launched in January 2022. While MCCPDC is primarily directed to people who are paying cash for drugs, it does take insurance from select plans. And even for people who are covered by other insurers, the cost of drugs from Mr. Cuban’s company may be less than their out-of-pocket costs if they did go through their payer.

The low pricing of Yusimry is welcome, said Marcus Snow, MD, an assistant professor in the division of rheumatology at the University of Nebraska Medical Center, Omaha, but he pointed out that it is still a very expensive drug. “For patients who can’t afford Humira due to poor insurance coverage and high out-of-pocket costs, it is a welcome option. But it’s also unclear how many patients who lack adequate health insurance coverage can afford to pay $579 a month out of their own pockets.”
 

The biosimilars are coming

By early December 2022, the Food and Drug Administration had approved seven Humira biosimilars, and Amgen launched the first biosimilar to come on the market, Amjevita, soon afterward. By July 2023, half a dozen more are expected to enter the marketplace, said Steven Horvitz, managing director of EMC Analytics Group, a pharmaceutical research firm.

Mr. Horvitz agrees that the system is out of control, but it is unclear how much of an effect the low price tag on the Coherus product will have. “Some insurers may say, ‘we want the lowest price, and we don’t care about rebates,’ and will go with it,” he said. “PBMs [pharmacy benefit managers] are all about economics, so we have to see how many of their major clients will ask for the lowest price.”

Amgen has more or less followed the status quo on pricing for its biosimilar, but with a twist. It›s being offered at two different prices: $85,494 a year, which is only a 5% discount from Humira’s list price, or at $40,497 a year, a 55% discount. However, to date, the lower price has generally not been granted favorable formulary placement by PBMs. The plans that adopt the higher-priced biosimilar will get bigger rebates, but patients with coinsurance and deductibles will pay more out of pocket.

It is yet unknown how the pricing on Yusimry will affect the biosimilars ready to launch. “Will it give them pause for thought or not make any difference?” Mr. Horvitz said. “The companies do not reveal their pricing before the fact, so we have to wait and see.”

Large PBMs have not jumped at the opportunity to offer the Coherus biosimilar, but SmithRx, which bills itself as “next-generation pharmacy benefits management,” announced that it will offer Yusimry to its members at a discount of more than 90%.

“Unlike traditional PBMs, SmithRx prioritizes transparency and up-front cost savings. Humira is often an employer’s top drug expense so offering a low-cost alternative will have significant impact,” Jake Frenz, CEO and founder of SmithRx, said in a statement. “We’re excited to work with Cost Plus Drugs to bring this biosimilar to our members – and significantly reduce costs for them and their employers.”

MILAN – The impact of the COVID-19 pandemic on patients with rheumatic and nonrheumatic autoimmune diseases is ongoing and not yet fully comprehended. New data presented at the annual European Congress of Rheumatology, primarily derived from the global COVID-19 in Autoimmune Diseases (COVAD) survey but not limited to it, provide reassurance regarding the protection and safety of COVID-19 vaccines for older and younger adults, as well as for pregnant and breastfeeding women. These data also explore the influence of underlying diseases and medications on breakthrough SARS-CoV-2 infections and infection outcomes.

Safety of vaccines in patients with autoimmune or immune-mediated diseases

Following vaccination, even with low levels of antibodies, the risk of severe COVID-19 remains relatively low for patients who receive immunosuppressive therapy for various immune-mediated inflammatory diseases (IMIDs). This encouraging finding comes from the Nor-vaC study, presented by Hilde Ørbo, MD, of the Center for Treatment of Rheumatic and Musculoskeletal Diseases, Diakonhjemmet Hospital, Oslo.

During the presentation, Dr. Ørbo stated: “We did not find any specific diagnosis or medication associated with a significantly higher risk of hospitalization.” Receiving booster doses of the vaccine, having high levels of anti-spike antibodies after vaccination, and achieving hybrid immunity are correlated with further reductions in the risk of breakthrough SARS-CoV-2 infections.

Dr. Hilde Ørbo

Between Feb. 15, 2021, and Feb. 15, 2023, COVID-19 affected a similar proportion among the 729 patients and 350 healthy control persons (67% and 68%, respectively). Among the patients, 22 reported severe COVID-19, whereas none of the healthy control persons did. However, there were no fatalities among the patients. The study cohort consisted of patients with various IMIDs; 70% had an inflammatory joint disease. The use of immunosuppressive medications also varied, with 63% of patients using tumor necrosis factor inhibitors, either as monotherapy or in combination with other treatments, and other patients taking medications such as methotrexate, interleukin inhibitors, Janus kinase inhibitors, vedolizumab (Entyvio), and others.

While being older than 70 years and the presence of comorbidities were identified as risk factors for severe COVID-19, there was a significant reduction in risk with each additional vaccine dose. These results support the protective role of repeated COVID-19 vaccination for patients with IMIDs who are receiving immunosuppressive therapies; they yield a favorable prognosis even with the Omicron variant.

The study further compared the risk of severe COVID-19 between a group with hybrid immunity (having received three vaccine doses and experiencing breakthrough infection with the Omicron variant) and a group that received a fourth vaccine dose within the same time frame. The difference was striking: Hybrid immunity was associated with a 5.8-fold decrease in risk, compared with four-dose vaccination (P < .0001).

The level of antibodies, measured 2-4 weeks after the last vaccination, was predictive of the risk of breakthrough COVID-19. An antibody level above 6000 binding antibody units/mL after vaccination was significantly associated with a reduction in risk. “We can conclude that patients who receive multiple vaccine doses have a lower risk of COVID-19,” Dr. Ørbo said. “In patients who recently experienced breakthrough infections, the administration of a booster vaccine dose might be delayed.”

EULAR

“The virus has undergone changes throughout the pandemic, while the vaccines have remained relatively stable. Are we anticipating more infections over time?” asked Hendrik Schulze-Koops, MD, PhD, of Ludwig Maximilians University of Munich (Germany), the session moderator. In response, Dr. Ørbo stated that 85% of the recorded infections in the study occurred after the emergence of the Omicron variant, and time was considered a covariable in the analysis.

These data shed light on a topic discussed by Pedro Machado, MD, PhD, professor and consultant in rheumatology and neuromuscular diseases at University College London, during his scientific session talk entitled, “Unsolved Issues of COVID Vaccination and Re-vaccination.” Dr. Machado referred to the VROOM study published in 2022, which examined the interruption of methotrexate for 2 weeks following booster administration. Both groups demonstrated a significant antibody response, but the group that stopped taking methotrexate showed double the antibody titers.

However, he emphasized, “what remains unknown is the clinical relevance of these differences in terms of severe infection, hospitalization, or even death. The potential benefit of increased immunogenicity by interrupting conventional synthetic disease-modifying antirheumatic drugs [csDMARDs] such as methotrexate before or after vaccination needs to be balanced against the potential risk of disease flare. Ultimately, decision-making should be individualized based on factors such as comorbidities, disease activity, and other considerations.” The results presented by Dr. Ørbo suggest that, while there may be a clinical difference in terms of severe infection, the overall prognosis for vaccinated patients is reasonably good.

Regarding other DMARDs, such as biologics, the approach may differ. Dr. Machado suggested: “In patients using rituximab or other B cell–depleting therapies, SARS-CoV-2 vaccination should be scheduled in a way that optimizes vaccine immunogenicity. A minimum of 10 B cells/mcL of blood is likely a relevant threshold above which a sufficient cellular and immune response is established.”
 

COVID vaccines are safe for pregnant and breastfeeding women

According to data from the COVAD study, which comprised two global cross-sectional surveys conducted in 2021 and 2022, the COVID-19 vaccine appeared safe for pregnant and breastfeeding women with autoimmune diseases (AID).

Presenter Laura Andreoli, MD, PhD, of the University of Brescia (Italy), said that, although pregnant patients with AID reported more adverse events related to vaccination, these rates were not significantly higher than those among pregnant, healthy control persons who were without AID. No difference in adverse events was observed between breastfeeding women and healthy control persons, and the incidence of disease flares did not significantly differ among all groups.

“In summary, this study provides initial insights into the safety of COVID-19 vaccination during the gestational and postpartum periods in women with autoimmune diseases. These reassuring observations will hopefully improve clinician-patient communication and address hesitancy towards COVID-19 vaccination, as the benefits for the mother and fetus through passive immunization appear to outweigh potential risks,” Dr. Andreoli said in an interview.

“The large number of participants and the global geographical spread of the COVAD survey were very beneficial in gaining access to this important subset of patients,” added Dr. Andreoli. However, she acknowledged that patients with low socioeconomic status and/or high disability were likely underrepresented. While no data on pregnancy outcomes have been collected thus far, Dr. Andreoli expressed the desire to include them in the study’s follow-up.

The COVAD survey data also indicate that, in general, vaccine hesitancy among patients with AID is decreasing; from 2021 to 2022, it declined from 16.5% to 5.1%, as Dr. Machado indicated in his presentation.
 

Multiple factors contribute to breakthrough infections

The risk of breakthrough SARS-CoV-2 infections after vaccination varies among patients with rheumatoid arthritis and rheumatic or nonrheumatic autoimmune diseases, primarily depending on the underlying condition rather than the immunosuppressive medication. Environmental factors also appear to play a role. This complex landscape emerges from a further analysis of the COVAD survey dataset.

Alessia Alunno, MD, PhD, of the University of L’Aquila (Italy), presented a detailed and occasionally counterintuitive picture of similarities and differences among young adult patients (aged 18-35 years), mostly women, with various rheumatic and nonrheumatic diseases in relation to COVID-19. Most notably, the type of disease seemed to have more significance than the immunosuppression resulting from the treatment regimen. This held true for vaccine safety as well as for the risk of breakthrough COVID-19 and symptom profiles.

Patients with rheumatic disease (RMD) and nonrheumatic autoimmune disease (nr-AD) had significantly different therapeutic profiles on average. Before vaccination, 45% of patients with RMD used glucocorticoids (GC), and 91% used immunosuppressants (IS). In contrast, only 9.5% of nr-AD patients used GC, and 21% were taking IS.

Interestingly, the overall prevalence of reported SARS-CoV-2 infections was not influenced by medication and was practically identical (25% to 28%) across all groups. However, there were intriguing differences in the occurrence of infections before and after vaccination between disease groups. Prevaccine infections were less frequent among patients with RMD compared with healthy control persons (adjusted odds ratio, 0.6), while the rates were similar among patients with nr-AD and healthy control persons. On the other hand, breakthrough infections were more frequent in patients with RMD (aOR, 2.7), whereas the rate was similar between healthy control persons and patients with nr-AD.

Despite a much lower rate of GC/IS use, patients with nr-AD experienced repeated infections more frequently. In contrast, patients with RMD were less prone to multiple infections, even compared with healthy control persons (aOR, 0.5).

Regarding the disease profile, fewer than 5% of all infected patients required advanced therapies for SARS-CoV-2 infection. Notably, all SARS-CoV-2 infections in patients with nr-AD were symptomatic, whereas among patients with RMD and healthy control persons, the incidence of asymptomatic infections was 3%. The rate of hospital admissions was 4% for patients with RMD, compared with 2% for patients with nr-AD and 1% for control persons. The RMD group exhibited some differences between prevaccine infections and breakthrough infections, including a significantly lower frequency of loss of smell and taste during breakthrough infections. Overall, patients with RMD and COVID-19 experienced cough, runny nose, throat pain, nausea, and vomiting more frequently. In contrast, patients with nr-AD had a much higher risk of skin rashes during breakthrough infections (aOR, 8.7).

Vaccine adverse events (AEs) were also influenced by the underlying disease. Patients with RMD and those with nr-AD were more likely to experience mild AEs after the first or second dose, compared with healthy control persons (adjusted OR, 2.4 and 2.0, respectively). The most common early, mild AEs across all groups were injection-site pain, headache, and fatigue, but they occurred more frequently in the nr-AD group than in the RMD or healthy control group. Additionally, fever and chills occurred more frequently among the nr-AD group. Late, mild AEs and severe AEs were rare and affected all groups equally.

“The overall incidence of AEs was very low. Our results certainly do not undermine the safety of vaccines,” Dr. Alunno said.

Disease flares were more common after vaccination (10% with RMD and 7% with nr-AD) than after infection (5% with RMD and 1.5% with nr-AD). Furthermore, in many cases, after vaccination, flares required a change of medications, particularly for patients with RMD.

Dr. Naveen Ravichandran

Additional results from the COVAD survey from January to July 2022, presented by Naveen Ravichandran, MD, DM, of Sanjay Gandhi Postgraduate Institute of Medical Sciences, Lucknow, India, revealed a higher prevalence (OR, 1.2; P = .001) of breakthrough infections among patients with RA. A total of 22.6% of patients with RA experienced breakthrough infections, compared with 20.6% for patients with other autoimmune rheumatic diseases and 18.4% of healthy control persons. Hospitalizations and the need for advanced treatment were also more common among patients with RA (30.9%) than among healthy control persons (13.9%). Patients with RA who had breakthrough infections tended to be older (closer to 50 years of age on average) and female, and they were more likely to have comorbidities and mental disorders. The human development index of the patient’s country of residence also played a role. Further research is necessary to understand how breakthrough infection outcomes are affected by a patient’s socioeconomic situation.

According to Dr. Ravichandran, medication was not a significant factor, except for the use of steroids and rituximab, which were associated with a higher risk of severe COVID-19 and hospitalization. Patients using rituximab, in particular, faced significantly increased odds for hospitalization (OR, 3.4) and severe breakthrough COVID-19 (OR, 3.0).

Session moderator Kim Lauper, MD, of the University of Geneva, cautioned: “The roles of disease and medication are challenging to separate. Some diseases require a more aggressive immunosuppressive regimen. It’s possible that different diseases affect the immune system differently, but it is not easy to demonstrate.”

The complications observed in the data warrant further study, as mentioned by Dr. Schulze-Koops: “We have a problem tied to the time line of the pandemic, where we had different viruses, different population behaviors, different treatments, and different standards of care over time. We also have differences between ethnic communities and regions of the world. But most importantly, we have different viruses: From the original strain to Delta to Omicron, we know they have very different clinical outcomes. I believe we need more scientific research to unravel these factors.”

MILAN – The impact of the COVID-19 pandemic on patients with rheumatic and nonrheumatic autoimmune diseases is ongoing and not yet fully comprehended. New data presented at the annual European Congress of Rheumatology, primarily derived from the global COVID-19 in Autoimmune Diseases (COVAD) survey but not limited to it, provide reassurance regarding the protection and safety of COVID-19 vaccines for older and younger adults, as well as for pregnant and breastfeeding women. These data also explore the influence of underlying diseases and medications on breakthrough SARS-CoV-2 infections and infection outcomes.

Safety of vaccines in patients with autoimmune or immune-mediated diseases

Following vaccination, even with low levels of antibodies, the risk of severe COVID-19 remains relatively low for patients who receive immunosuppressive therapy for various immune-mediated inflammatory diseases (IMIDs). This encouraging finding comes from the Nor-vaC study, presented by Hilde Ørbo, MD, of the Center for Treatment of Rheumatic and Musculoskeletal Diseases, Diakonhjemmet Hospital, Oslo.

During the presentation, Dr. Ørbo stated: “We did not find any specific diagnosis or medication associated with a significantly higher risk of hospitalization.” Receiving booster doses of the vaccine, having high levels of anti-spike antibodies after vaccination, and achieving hybrid immunity are correlated with further reductions in the risk of breakthrough SARS-CoV-2 infections.

Dr. Hilde Ørbo

Between Feb. 15, 2021, and Feb. 15, 2023, COVID-19 affected a similar proportion among the 729 patients and 350 healthy control persons (67% and 68%, respectively). Among the patients, 22 reported severe COVID-19, whereas none of the healthy control persons did. However, there were no fatalities among the patients. The study cohort consisted of patients with various IMIDs; 70% had an inflammatory joint disease. The use of immunosuppressive medications also varied, with 63% of patients using tumor necrosis factor inhibitors, either as monotherapy or in combination with other treatments, and other patients taking medications such as methotrexate, interleukin inhibitors, Janus kinase inhibitors, vedolizumab (Entyvio), and others.

While being older than 70 years and the presence of comorbidities were identified as risk factors for severe COVID-19, there was a significant reduction in risk with each additional vaccine dose. These results support the protective role of repeated COVID-19 vaccination for patients with IMIDs who are receiving immunosuppressive therapies; they yield a favorable prognosis even with the Omicron variant.

The study further compared the risk of severe COVID-19 between a group with hybrid immunity (having received three vaccine doses and experiencing breakthrough infection with the Omicron variant) and a group that received a fourth vaccine dose within the same time frame. The difference was striking: Hybrid immunity was associated with a 5.8-fold decrease in risk, compared with four-dose vaccination (P < .0001).

The level of antibodies, measured 2-4 weeks after the last vaccination, was predictive of the risk of breakthrough COVID-19. An antibody level above 6000 binding antibody units/mL after vaccination was significantly associated with a reduction in risk. “We can conclude that patients who receive multiple vaccine doses have a lower risk of COVID-19,” Dr. Ørbo said. “In patients who recently experienced breakthrough infections, the administration of a booster vaccine dose might be delayed.”

“The virus has undergone changes throughout the pandemic, while the vaccines have remained relatively stable. Are we anticipating more infections over time?” asked Hendrik Schulze-Koops, MD, PhD, of Ludwig Maximilians University of Munich (Germany), the session moderator. In response, Dr. Ørbo stated that 85% of the recorded infections in the study occurred after the emergence of the Omicron variant, and time was considered a covariable in the analysis.

These data shed light on a topic discussed by Pedro Machado, MD, PhD, professor and consultant in rheumatology and neuromuscular diseases at University College London, during his scientific session talk entitled, “Unsolved Issues of COVID Vaccination and Re-vaccination.” Dr. Machado referred to the VROOM study published in 2022, which examined the interruption of methotrexate for 2 weeks following booster administration. Both groups demonstrated a significant antibody response, but the group that stopped taking methotrexate showed double the antibody titers.

However, he emphasized, “what remains unknown is the clinical relevance of these differences in terms of severe infection, hospitalization, or even death. The potential benefit of increased immunogenicity by interrupting conventional synthetic disease-modifying antirheumatic drugs [csDMARDs] such as methotrexate before or after vaccination needs to be balanced against the potential risk of disease flare. Ultimately, decision-making should be individualized based on factors such as comorbidities, disease activity, and other considerations.” The results presented by Dr. Ørbo suggest that, while there may be a clinical difference in terms of severe infection, the overall prognosis for vaccinated patients is reasonably good.

Regarding other DMARDs, such as biologics, the approach may differ. Dr. Machado suggested: “In patients using rituximab or other B cell–depleting therapies, SARS-CoV-2 vaccination should be scheduled in a way that optimizes vaccine immunogenicity. A minimum of 10 B cells/mcL of blood is likely a relevant threshold above which a sufficient cellular and immune response is established.”
 

COVID vaccines are safe for pregnant and breastfeeding women

According to data from the COVAD study, which comprised two global cross-sectional surveys conducted in 2021 and 2022, the COVID-19 vaccine appeared safe for pregnant and breastfeeding women with autoimmune diseases (AID).

Presenter Laura Andreoli, MD, PhD, of the University of Brescia (Italy), said that, although pregnant patients with AID reported more adverse events related to vaccination, these rates were not significantly higher than those among pregnant, healthy control persons who were without AID. No difference in adverse events was observed between breastfeeding women and healthy control persons, and the incidence of disease flares did not significantly differ among all groups.

“In summary, this study provides initial insights into the safety of COVID-19 vaccination during the gestational and postpartum periods in women with autoimmune diseases. These reassuring observations will hopefully improve clinician-patient communication and address hesitancy towards COVID-19 vaccination, as the benefits for the mother and fetus through passive immunization appear to outweigh potential risks,” Dr. Andreoli said in an interview.

“The large number of participants and the global geographical spread of the COVAD survey were very beneficial in gaining access to this important subset of patients,” added Dr. Andreoli. However, she acknowledged that patients with low socioeconomic status and/or high disability were likely underrepresented. While no data on pregnancy outcomes have been collected thus far, Dr. Andreoli expressed the desire to include them in the study’s follow-up.

The COVAD survey data also indicate that, in general, vaccine hesitancy among patients with AID is decreasing; from 2021 to 2022, it declined from 16.5% to 5.1%, as Dr. Machado indicated in his presentation.
 

Multiple factors contribute to breakthrough infections

The risk of breakthrough SARS-CoV-2 infections after vaccination varies among patients with rheumatoid arthritis and rheumatic or nonrheumatic autoimmune diseases, primarily depending on the underlying condition rather than the immunosuppressive medication. Environmental factors also appear to play a role. This complex landscape emerges from a further analysis of the COVAD survey dataset.

Alessia Alunno, MD, PhD, of the University of L’Aquila (Italy), presented a detailed and occasionally counterintuitive picture of similarities and differences among young adult patients (aged 18-35 years), mostly women, with various rheumatic and nonrheumatic diseases in relation to COVID-19. Most notably, the type of disease seemed to have more significance than the immunosuppression resulting from the treatment regimen. This held true for vaccine safety as well as for the risk of breakthrough COVID-19 and symptom profiles.

Patients with rheumatic disease (RMD) and nonrheumatic autoimmune disease (nr-AD) had significantly different therapeutic profiles on average. Before vaccination, 45% of patients with RMD used glucocorticoids (GC), and 91% used immunosuppressants (IS). In contrast, only 9.5% of nr-AD patients used GC, and 21% were taking IS.

Interestingly, the overall prevalence of reported SARS-CoV-2 infections was not influenced by medication and was practically identical (25% to 28%) across all groups. However, there were intriguing differences in the occurrence of infections before and after vaccination between disease groups. Prevaccine infections were less frequent among patients with RMD compared with healthy control persons (adjusted odds ratio, 0.6), while the rates were similar among patients with nr-AD and healthy control persons. On the other hand, breakthrough infections were more frequent in patients with RMD (aOR, 2.7), whereas the rate was similar between healthy control persons and patients with nr-AD.

Despite a much lower rate of GC/IS use, patients with nr-AD experienced repeated infections more frequently. In contrast, patients with RMD were less prone to multiple infections, even compared with healthy control persons (aOR, 0.5).

Regarding the disease profile, fewer than 5% of all infected patients required advanced therapies for SARS-CoV-2 infection. Notably, all SARS-CoV-2 infections in patients with nr-AD were symptomatic, whereas among patients with RMD and healthy control persons, the incidence of asymptomatic infections was 3%. The rate of hospital admissions was 4% for patients with RMD, compared with 2% for patients with nr-AD and 1% for control persons. The RMD group exhibited some differences between prevaccine infections and breakthrough infections, including a significantly lower frequency of loss of smell and taste during breakthrough infections. Overall, patients with RMD and COVID-19 experienced cough, runny nose, throat pain, nausea, and vomiting more frequently. In contrast, patients with nr-AD had a much higher risk of skin rashes during breakthrough infections (aOR, 8.7).

Vaccine adverse events (AEs) were also influenced by the underlying disease. Patients with RMD and those with nr-AD were more likely to experience mild AEs after the first or second dose, compared with healthy control persons (adjusted OR, 2.4 and 2.0, respectively). The most common early, mild AEs across all groups were injection-site pain, headache, and fatigue, but they occurred more frequently in the nr-AD group than in the RMD or healthy control group. Additionally, fever and chills occurred more frequently among the nr-AD group. Late, mild AEs and severe AEs were rare and affected all groups equally.

“The overall incidence of AEs was very low. Our results certainly do not undermine the safety of vaccines,” Dr. Alunno said.

Disease flares were more common after vaccination (10% with RMD and 7% with nr-AD) than after infection (5% with RMD and 1.5% with nr-AD). Furthermore, in many cases, after vaccination, flares required a change of medications, particularly for patients with RMD.

Dr. Naveen Ravichandran

Additional results from the COVAD survey from January to July 2022, presented by Naveen Ravichandran, MD, DM, of Sanjay Gandhi Postgraduate Institute of Medical Sciences, Lucknow, India, revealed a higher prevalence (OR, 1.2; P = .001) of breakthrough infections among patients with RA. A total of 22.6% of patients with RA experienced breakthrough infections, compared with 20.6% for patients with other autoimmune rheumatic diseases and 18.4% of healthy control persons. Hospitalizations and the need for advanced treatment were also more common among patients with RA (30.9%) than among healthy control persons (13.9%). Patients with RA who had breakthrough infections tended to be older (closer to 50 years of age on average) and female, and they were more likely to have comorbidities and mental disorders. The human development index of the patient’s country of residence also played a role. Further research is necessary to understand how breakthrough infection outcomes are affected by a patient’s socioeconomic situation.

According to Dr. Ravichandran, medication was not a significant factor, except for the use of steroids and rituximab, which were associated with a higher risk of severe COVID-19 and hospitalization. Patients using rituximab, in particular, faced significantly increased odds for hospitalization (OR, 3.4) and severe breakthrough COVID-19 (OR, 3.0).

Session moderator Kim Lauper, MD, of the University of Geneva, cautioned: “The roles of disease and medication are challenging to separate. Some diseases require a more aggressive immunosuppressive regimen. It’s possible that different diseases affect the immune system differently, but it is not easy to demonstrate.”

The complications observed in the data warrant further study, as mentioned by Dr. Schulze-Koops: “We have a problem tied to the time line of the pandemic, where we had different viruses, different population behaviors, different treatments, and different standards of care over time. We also have differences between ethnic communities and regions of the world. But most importantly, we have different viruses: From the original strain to Delta to Omicron, we know they have very different clinical outcomes. I believe we need more scientific research to unravel these factors.”
