Atopic Dermatitis

With so many treatment options available for atopic dermatitis (AD) and more in the pipeline, one common question Raj Chovatiya, MD, PhD, hears from his fellow dermatologists is: How do I choose the right therapy for my patients?

“There isn’t going to be a one-size-fits-all approach, and it may be impossible to differentiate, given that these agents are not likely to be studied head-to-head,” Dr. Chovatiya, assistant professor in the department of dermatology at Northwestern University, Chicago, said during the Revolutionizing Atopic Dermatitis (RAD) Virtual Conference.

Dr. Chovatiya

He shared a list of factors to consider when engaged in shared decision-making with patients about their AD treatment options. These include:

• Severity of disease (mild vs moderate vs severe).
• Extent of disease (low vs high body surface area).
• Rapidity of drug onset (hours vs days vs weeks).
• Depth of response based on different endpoints such as itch and number of lesions.
• Long-term efficacy (durability on treatment vs off treatment).
• Adverse events (cutaneous vs systemic).
• Black box warnings (present vs absent).
• Tolerance (selective areas vs the entire skin).
• Vehicle (ointment vs cream).
• Patient preference. “This may be the biggest driver; what do patients want?” Dr. Chovatiya said.
• Access to the drug. Is it easily obtainable for the patient?

He concluded his remarks by posing a question to attendees: “Are we closer to living in a topical steroid–free world for AD? Is that what we want?” he asked. “I wholeheartedly say that’s what we’ve been working toward all these years, and we should keep up the good fight. We have more data for targeted therapy to treat very specific disease with very specific outcomes and endpoints, because I think that’s [what] we all dream about in dermatology.”

Dr. Chovatiya disclosed that he is speaker for and/or a consultant and advisory board member to many pharmaceutical companies.

Safety data spanning up to 5 years from clinical trials of adolescents and adults using 15 mg or 30 mg of upadacitinib to treat moderate to severe atopic dermatitis (AD) indicates that rates of treatment-emergent adverse events remained low and consistent, with no new safety risks identified, underscoring the medication’s stable safety profile over an extended duration.

Those are among the key findings from an integrated analysis of long-term upadacitinib use presented by Christopher G. Bunick, MD, PhD, during a late-breaking abstract session at the Revolutionizing Atopic Dermatitis Virtual Conference. Upadacitinib (Rinvoq) is an oral Janus kinase (JAK) inhibitor, approved by the Food and Drug Administration for adults and pediatric patients aged 12 years of age and older with refractory, moderate to severe AD in January 2022.

“What makes this study special is that these patients are followed for 260 weeks, or 5 years, and it encompasses over 7,000 patient-years of exposure,” said Dr. Bunick, associate professor of dermatology at Yale University, New Haven, Connecticut. “This is a milestone because it’s the longest safety study ever published for any systemic drug for AD.”

He and his colleagues evaluated the safety data for up to 5 years of upadacitinib 15 mg and 30 mg use in adolescents and adults with moderate to severe AD, based on the results of integrated data from three ongoing global multicenter phase 3 trials: Measure Up 1, Measure Up 2, and AD Up. Patients in the trials were randomized 1:1:1 to receive oral upadacitinib 15 mg, upadacitinib 30 mg, or placebo once daily alone (Measure Up 1 and 2) or with concomitant topical corticosteroids (AD Up). At week 16, patients receiving 15 mg or 30 mg upadacitinib during the double-blind period continued their assigned treatment in the blinded extension (BE) period, whereas patients receiving placebo were randomized 1:1 to receive either 15 mg or 30 mg upadacitinib in the BE period. The integrated analysis included 2683 patients (529 adolescents and 2154 adults) who received at least one dose of upadacitinib. Of these, 1337 received the 15-mg dose, while 1346 received the 30-mg dose. The researchers analyzed treatment-emergent events of special interest as exposure-adjusted rates per 100 patient-years (PY) for the entire treatment period to adjust for potentially different follow-up durations.

According to Dr. Bunick, researchers often refer to “100 patient-years” in safety analyses to measure how common certain events are. “It is a straightforward way to convey the collective experience of the study’s participants over time,” he told this news organization. “For instance, if 100 patients are each monitored for 1 year, or 50 patients for 2 years each, both scenarios amount to 100 patient-years. This metric allows clinicians to understand how often certain adverse events occur across a diverse group over a specific time frame, providing a clear picture of long-term safety.”

Upadacitinib trials in atopic dermatitis have included diverse patient groups with varying risk factors. “Patients were not cherry-picked,” he said. “What I mean by that is that about 50% of patients enrolled in these trials had, at baseline, at least one cardiovascular risk factor: about 30% used tobacco; 10% had hypertension, and 5% had a history of a cardiovascular event.” In addition, about 15% were over age 50 with one cardiovascular risk factor and about 20% had a body mass index (BMI) greater than 30 kg/m². Among women in the study, about 20% were on oral contraceptives, yet none developed a venous thromboembolism (VTE).

In the integrated analysis, the rate of treatment-emergent adverse events that led to discontinuation of upadacitinib was about 4.2 events per 100 PY, “meaning that this medicine shows durability,” Dr. Bunick said. “Very few people are discontinuing due to adverse events.”

Serious and opportunistic infections ranged from 1.6 to 2.8 events per 100 PY, but these were stable across the 1- to 5-year time points. The rates of active TB were less than 0.1 per 100 PY, while the rates of herpes zoster ranged from 3.5 to 5.5 events per 100 PY. “The key take-home point here is that 5% or less of the patients at baseline had received the shingles vaccine, so it’s very important to talk to patients about receiving the shingles vaccine before they go on upadacitinib,” Dr. Bunick advised, because “this could reduce risk of herpes zoster occurring in upadacitinib-treated patients substantially.”

In other findings, incidence rates of nonmelanoma skin cancer (NMSC) ranged between 0.3 and 0.4 per 100 PY, while the rate of malignancy excluding NMSC ranged between 0.3 and 0.4 per 100 PY. Meanwhile, the rates of gastrointestinal perforations and VTE stood at 0.1 per 100 PY or lower, and MACE incidence rates ranged from 0.1 to 0.2 per 100 PY.

During his presentation, Dr. Bunick compared findings related to malignancy (excluding NMSC), MACE, and VTE to other published real-world background rates observed in moderate to severe AD populations. He noted that, while the malignancy rate in the current trial ranged from 0.3 to 0.4 per 100 PY, an observational study of more than 66,000 AD patients in the United Kingdom reported a malignancy (excluding NMSC) background incidence rate of 0.33 per 100 PY, and SEER data estimate that the malignancy incidence rate in the US general population is 0.45 per 100 PY. “Therefore, patients on upadacitinib at the 5-year mark are right at the AD population baseline risk,” he said.

And while the incidence rate of MACE in the current trial ranged from less than 0.1 to 0.2 per 100 PY, the background incidence rate of MACE in a Danish observational study of more than 2,500 patients with moderate to severe AD was 0.63 per 100 PY. “This suggests that there may be an anti-inflammatory and even a cardiovascular protective effect for patients on upadacitinib,” Dr. Bunick said.

As for VTE, the incidence rate in the current trial was 0.1 per 100 PY, but VTE background incidence rate observed in a moderate to severe AD population in the United States is 0.31 per 100 PY. “Again, this suggests anti-inflammatory and cardiovascular protective effects of upadacitinib in AD patients at the 5-year mark,” he said. “Reporting of MACE, VTE, and malignancy (excluding NMSC) in upadacitinib phase 3 clinical trials for AD generally reflects the background observations of these events in the AD population.”

He acknowledged certain limitations of the study, including the fact that observational data may overestimate the risk of adverse events.

Discussing the incidence rates for MACE, VTE, and malignancy in upadacitinib AD trials, Dr. Bunick remarked, “these are rock-bottom rates that have been low through 5 years of treatment.”

Dr. Bunick disclosed that he has received grant or research support from AbbVie (the manufacturer of upadacitinib), Almirall, Ortho Dermatologics, Timber, and Palvella. He is also a consultant and/or an adviser to AbbVie, Almirall, Apogee, Connect Bropharma, Arcutis, Eli Lilly, Novartis, Pfizer, Sanofi-Regeneron, Ortho Dermatologics, Leo Pharma, and UCB.

The prevalence of clinically meaningful conjunctivitis in patients taking dupilumab for atopic dermatitis (AD) is likely about 2%, and it most often occurs in the first 16 weeks of therapy.

Those are key findings from an analysis of published trials of dupilumab for AD and other conditions that study author Matthew Zirwas, MD, presented during a late-breaking abstract session at the Revolutionizing Atopic Dermatitis (RAD) Virtual Conference.

Adults with AD have a significant and disease severity–dependent increased risk of developing ocular surface diseases, including conjunctivitis and keratitis, compared with the general population and independent of any drug effect, according to Dr. Zirwas, a dermatologist with Probity Medical Research of Columbus, Ohio.

Dupilumab inhibits signaling of interleukin (IL)-4 and IL-13, which drive type 2 inflammatory diseases such as AD, asthma, chronic rhinosinusitis with nasal polyposis (CRSwNP), eosinophilic esophagitis (EoE), prurigo nodularis (PN), and chronic spontaneous urticaria (CSU).

In randomized, placebo-controlled trials of dupilumab in patients with moderate to severe AD, conjunctivitis was reported in more patients who received dupilumab treatment than in placebo-treated patients.

“When it comes to dupilumab-induced conjunctivitis, we have a good idea of the etiology, but the question of how frequently it occurs versus how frequently the conjunctivitis is unrelated to dupilumab is an interesting one,” he said. “How often is it clinically meaningful? What is it that is so unique about AD patients? We’ve all heard that it is a unique adverse event that only happens to people with AD and not to people using dupilumab for other indications. Where it gets interesting to me is how do we differentiate the cases that are dupilumab induced versus the cases that are just part of the underlying AD process?”

For their analysis, Dr. Zirwas and co-authors reviewed the incidence of conjunctivitis adverse events in patients from 15 completed, randomized, double-blind placebo-controlled trials evaluating dupilumab in AD, asthma, CRSwNP, EoE, PN, and CSU, along with the severity and resolution of conjunctivitis events in adults with AD.

Of the 15 trials, 7 were conducted in patients with AD: 4 in adults, 1 in adolescents, 1 in school-aged children, and 1 in preschoolers. One of the AD trials, LIBERTY AD CHRONOS, extends 52 weeks. The remaining eight trials of patients with asthma, CRSwNP, EoE, PN, and CSU lasted 24-52 weeks.

In the non-AD trials, the researchers observed that conjunctivitis rates were generally in the 1%-3% range, with less pronounced or no differences between the dupilumab and placebo groups. In the AD trials, conjunctivitis rates were higher in patients receiving dupilumab, compared with those receiving placebo across age groups.

In the 16-week SOLO 1 & 2 and AD-1021 monotherapy trials, 12 conjunctivitis events occurred in 517 patients who received placebo (2%), compared with 103 of 1047 patients (9.84%) who received dupilumab. Of the dupilumab-associated conjunctivitis cases, 80 (78%) patients recovered by the end of the trials. Of the 23 cases of conjunctivitis that did not recover or dropped out of the trial, 15 were among the 529 patients who received 300 mg dupilumab once every 2 weeks (q2w) (3%) and eight were among the 518 who received 300 mg dupilumab once weekly (qw) (2%).

In the 52-week LIBERTY AD CHRONOS trial, 29 conjunctivitis events occurred in 315 patients who received placebo plus topical corticosteroid (TCS) (9%), compared with 113 of 425 patients (27%) who received dupilumab plus TCS. Of these, 103 (91%) recovered by the end of the trial. Of the 11 patients with conjunctivitis who did not recover or dropped out of the trial, 3 were among the 110 patients who received 300 mg dupilumab q2w plus TCS (3%), and 8 were among the 315 who received 300 mg dupilumab qw plus TCS (3%).

“When I look at all of this data, I think that about 2% of people treated with dupilumab are going to get clinically very meaningful conjunctivitis that may be therapy limiting,” Dr. Zirwas concluded. “The vast majority of those cases appear to happen in the first 16 weeks. This is just not something we see in cases of patients treated with dupilumab treated for other reasons.”

Following his presentation, a meeting attendee asked Dr. Zirwas if conjunctivitis occurs more often in patients with facial dermatitis. “My perception is that it happens more often in people who have facial or eyelid dermatitis, but I’ve seen it in plenty of people who didn’t have any facial or eyelid dermatitis,” he said. “I have seen more conjunctivitis in people with more severe AD and more severe atopic comorbidities. That is anecdotal. The data that I have seen has been back and forth on this topic.”

Those are key findings from an analysis of published trials of dupilumab for AD and other conditions that study author Matthew Zirwas, MD, presented during a late-breaking abstract session at the Revolutionizing Atopic Dermatitis (RAD) Virtual Conference.

Adults with AD have a significant and disease severity–dependent increased risk of developing ocular surface diseases, including conjunctivitis and keratitis, compared with the general population and independent of any drug effect, according to Dr. Zirwas, a dermatologist with Probity Medical Research of Columbus, Ohio.

Dupilumab inhibits signaling of interleukin (IL)-4 and IL-13, which drive type 2 inflammatory diseases such as AD, asthma, chronic rhinosinusitis with nasal polyposis (CRSwNP), eosinophilic esophagitis (EoE), prurigo nodularis (PN), and chronic spontaneous urticaria (CSU).

In randomized, placebo-controlled trials of dupilumab in patients with moderate to severe AD, conjunctivitis was reported in more patients who received dupilumab treatment than in placebo-treated patients.

“When it comes to dupilumab-induced conjunctivitis, we have a good idea of the etiology, but the question of how frequently it occurs versus how frequently the conjunctivitis is unrelated to dupilumab is an interesting one,” he said. “How often is it clinically meaningful? What is it that is so unique about AD patients? We’ve all heard that it is a unique adverse event that only happens to people with AD and not to people using dupilumab for other indications. Where it gets interesting to me is how do we differentiate the cases that are dupilumab induced versus the cases that are just part of the underlying AD process?”

For their analysis, Dr. Zirwas and co-authors reviewed the incidence of conjunctivitis adverse events in patients from 15 completed, randomized, double-blind placebo-controlled trials evaluating dupilumab in AD, asthma, CRSwNP, EoE, PN, and CSU, along with the severity and resolution of conjunctivitis events in adults with AD.

Of the 15 trials, 7 were conducted in patients with AD: 4 in adults, 1 in adolescents, 1 in school-aged children, and 1 in preschoolers. One of the AD trials, LIBERTY AD CHRONOS, extends 52 weeks. The remaining eight trials of patients with asthma, CRSwNP, EoE, PN, and CSU lasted 24-52 weeks.

In the non-AD trials, the researchers observed that conjunctivitis rates were generally in the 1%-3% range, with less pronounced or no differences between the dupilumab and placebo groups. In the AD trials, conjunctivitis rates were higher in patients receiving dupilumab, compared with those receiving placebo across age groups.

In the 16-week SOLO 1 & 2 and AD-1021 monotherapy trials, 12 conjunctivitis events occurred in 517 patients who received placebo (2%), compared with 103 of 1047 patients (9.84%) who received dupilumab. Of the dupilumab-associated conjunctivitis cases, 80 (78%) patients recovered by the end of the trials. Of the 23 cases of conjunctivitis that did not recover or dropped out of the trial, 15 were among the 529 patients who received 300 mg dupilumab once every 2 weeks (q2w) (3%) and eight were among the 518 who received 300 mg dupilumab once weekly (qw) (2%).

In the 52-week LIBERTY AD CHRONOS trial, 29 conjunctivitis events occurred in 315 patients who received placebo plus topical corticosteroid (TCS) (9%), compared with 113 of 425 patients (27%) who received dupilumab plus TCS. Of these, 103 (91%) recovered by the end of the trial. Of the 11 patients with conjunctivitis who did not recover or dropped out of the trial, 3 were among the 110 patients who received 300 mg dupilumab q2w plus TCS (3%), and 8 were among the 315 who received 300 mg dupilumab qw plus TCS (3%).

“When I look at all of this data, I think that about 2% of people treated with dupilumab are going to get clinically very meaningful conjunctivitis that may be therapy limiting,” Dr. Zirwas concluded. “The vast majority of those cases appear to happen in the first 16 weeks. This is just not something we see in cases of patients treated with dupilumab treated for other reasons.”

Following his presentation, a meeting attendee asked Dr. Zirwas if conjunctivitis occurs more often in patients with facial dermatitis. “My perception is that it happens more often in people who have facial or eyelid dermatitis, but I’ve seen it in plenty of people who didn’t have any facial or eyelid dermatitis,” he said. “I have seen more conjunctivitis in people with more severe AD and more severe atopic comorbidities. That is anecdotal. The data that I have seen has been back and forth on this topic.”

Among patients with moderate-to-severe atopic dermatitis (AD) treated with the oral Janus kinase inhibitor upadacitinib for 4 or more weeks, more than half achieved clear or almost clear skin and 45% or more reported no or minimal itch, results from an analysis of registry data showed.

“We know from clinical trials that upadacitinib is effective, but we have very little real-world experience on its effectiveness,” presenting study author Melinda Gooderham, MD, medical director of the Skin Center for Dermatology in Peterborough, Ontario, Canada, said during a late-breaking abstract session at the Revolutionizing Atopic Dermatitis (RAD) Virtual Conference.

For the analysis, she and her coauthors evaluated the real-world clinical and patient-reported outcomes of 335 adults enrolled in the CorEvitas AD Registry from July 21, 2020, through Aug. 7, 2023. They included patients who were on upadacitinib for at least 4 weeks and persisted on the drug until the time of evaluation.

The CorEvitas AD Registry is a prospective, non-interventional registry of adults diagnosed with AD by a dermatologist or qualified dermatology practitioner. Outcomes measures included the proportion of patients who achieved skin clearance as defined by a Validated Investigators Global Assessment Scale for Atopic Dermatitis (vIGA) score of 0 or 1, an Eczema Area and Severity Index (EASI) score of 3 or less, a Peak Pruritus Numeric Rating Scale (PP-NRS) score of 0 or 1, Patient-Oriented Eczema Measure (POEM) scores of 0-2, Dermatology Life Quality Index (DLQI) scores of 0 or 1, or an Atopic Dermatitis Control Tool (ADCT) score of <7.

The researchers evaluated cross-sectional data from three different cohorts: data from the last registry visit (the overall cohort), data from a visit within 1 month to less than 5 months of upadacitinib initiation (the 1-5 months cohort), and data from a visit within 5-9 months following upadacitinib initiation (the 5-9 months cohort). They also conducted subgroup analyses of patients with prior use of biologics for AD (bio-experience) and those with no such history (bio-naive). Safety events were not assessed in this analysis.

The mean age of the 335 patients was 45.6 years, 51.6% were female, 64.2% were White, 64.2% were based in the United States and the rest were based in Canada. Most patients (70.8%) were treated with the 15-mg dose of upadacitinib. The median duration of treatment was 6.9 months. Slightly more than one-quarter of patients (28.1%) reported concomitant use of topical corticosteroids for AD, while 45.4% reported prior use of dupilumab and 6% reported prior use of tralokinumab.

Dr. Gooderham reported that 57.5% of patients in the total cohort total cohort achieved clear or almost clear skin (a vIGA-AD score of 0 or 1), with slight differences between the bio-naive (60.6%) and bio-experienced (54.1%) subgroups.

The other outcomes were similarly close between the 176 bio-naive and 159 bio-experienced patients. Specifically, 74.8% in the total cohort, 79.4% in the bio-naive subgroup, and 69.6% in the bio-experienced subgroup achieved an EASI score of 3 or less. In the measure of the worst itch in the past 24 hours, 45.3%, 47.7%, and 42.8% respectively achieved a PP-NRS of 0 or 1. In the patient-reported disease burden, 36.4%, 41%, and 31.4% achieved a POEM score of 0-2. In the quality of life measure, 39.8%, 42.8%, and 36.5% achieved a DLQI score of 0 or 1. In the measure of disease control, 69.3%, 70.5%, and 67.9% achieved an ADCT score of <7. In a combination of skin clearance and itch control, 40.9%, 43.2%, and 38.4% of the total cohort, bio-naive, and bio-experienced respectively achieved both an EASI score of 3 or less and a PP-NRS of 0 or 1.

The study outcomes were similar between the 1-5 months cohort and the 5-9 months cohort, but there was a trend toward more clearance the longer patients were on therapy.

“The findings suggest that low levels of disease severity are observed in patients on upadacitinib in a real-world setting,” Dr. Gooderham concluded. “This confirms what we see in the clinical trials.”

Patients with psoriasis being treated with biologics have a low overall risk for developing the paradoxical symptoms of eczema, with interleukin (IL)-23 inhibitors found to confer the lowest risk of the drug classes examined in a large observational analysis.

Using data from the British Association of Dermatologists Biologics and Immunomodulators Register (BADBIR) database, Ali Al-Janabi, MA, from the University of Manchester (England) and associates found that 273 (1%) of approximately 25,000 drug exposures in 13,699 biologic-treated patients with psoriasis were associated with paradoxical eczema.

The incidence of paradoxical eczema was found to vary by class. The highest rate was seen for IL-17 inhibitors, at 1.22 per 100,000 person-years, and the lowest rate was seen with IL-23 inhibitors, at 0.56 per 100,000 person-years. The respective incidence rates for tumor necrosis factor (TNF) inhibitors and IL-12/IL-23 inhibitors were a respective 0.94 and 0.80 per 100,000 person-years.

“Compared with TNF inhibitors, IL-23 inhibitor exposure was associated with significantly lower risk of paradoxical eczema,” the BADBIR Study Group reported in JAMA Dermatology. Indeed, patients treated with IL-23 inhibitors were 61% less likely than were those taking TNF-inhibitors to experience a paradoxical eczema event.

“These findings remained when restricting the analysis to first-line biologic exposures and were specific to this eczema phenotype” the group said.

Cautious Interpretation

As the corresponding author for the work, Mr. Al-Janabi observed in an email that the research needs to be replicated, and the findings need to be interpreted with caution.

“As well as usual clinical variables influencing biologic selection, clinicians could consider IL-23 inhibitors in patients with previous atopic dermatitis, hay fever, or paradoxical eczema episodes, as this class was associated with the lowest risk of paradoxical eczema,” he suggested.

A prior history of atopic dermatitis (AD) and hay fever appears to be particularly relevant, as both substantially upped the chances that paradoxical eczema would occur, with hazard ratios of 12.40 and 3.78, respectively. Increasing age also increased the risk, albeit slightly (hazard ratio [HR], 1.02 per year), and there was an apparent lower risk (HR, 0.60) comparing men and women.

The BADBIR Study Group authors believe that, to the best of their knowledge, this is the first study to compare paradoxical eczema risk by biologic class. “Based on clinical experience and prevalence of eczematous reactions reported in some IL-17 inhibitor clinical trials, we suspected an association between IL-17 inhibitor exposure and paradoxical eczema,” they wrote.

“While the incidence of paradoxical eczema was numerically highest among IL-17 inhibitor exposures, it was not significantly different from the incidence among TNF inhibitor exposures.” The low overall incidence of paradoxical eczema “may be reassuring for patients and clinicians,” they added, “but it is possible that the incidence was underestimated due to underreporting or exclusion of adverse events with insufficient detail.”

Details of the Analysis, Other Findings

To explore the risk of paradoxical eczema by biologic class and identify possible risk factors, the BADBIR Study Group performed a prospective cohort study using data held within the BADBIR database between September 2007 and December 2022.

Adults over the age of 18 year or older with plaque psoriasis and who had been treated with at least one of the following biologics were eligible for inclusion: the TNF inhibitors adalimumab, certolizumab pegol, etanercept, and infliximab; the IL-17 inhibitors bimekizumab, brodalumab, ixekizumab, and secukinumab; the IL-12/23 inhibitor ustekinumab; and the IL-23 inhibitors guselkumab, risankizumab, and tildrakizumab.

Patient records and adverse event data were reviewed to determine the incidence of paradoxical eczema events, using terms such as eczema, eczematized, eczematous, atopy, atopic, and dermatitis.

Of 24,952 drug exposures analyzed, the majority (11,819) were for TNF inhibitors, followed by IL-17 inhibitors (4,776), IL-12/23 inhibitors (6,423), and finally, IL-23 inhibitors (1,934).

Mr. Al-Janabi and coauthors reported that the median time to onset of paradoxical eczema events was 294 days — approximately 9.8 months. The earliest that these events were recorded was at 120 days (4 months), and the latest at 699 days (almost 2 years).

The face and neck were the most common sites affected (26% of exposures), with other sites including the limbs (23%), the trunk (13%), and hands or feet (12%). Itching (18%), redness (7%), and dryness (4%) were the most commonly reported symptoms.

The researchers noted that 21 patients had skin biopsies taken and “all showed spongiosis or a feature of eczema, with 1 having overlapping features of psoriasis.”

In the majority (92 %) of cases, patients experienced only one eczema event. Of the 20 patients who had more than one event, just over one-fifth of repeat events occurred after receiving the same biologic as for the index event. A quarter of events occurred after a different biologic of the same class had been used, and just over half of events occurred after a different class of biologic had been given.

Strengths and Limitations

The “large sample size and inclusion of multiple lines of exposure per participant” are strengths of the study, said the researchers. “We included data for all currently available biologics, originating from more than 160 dermatology centers in the UK and Ireland.”

They added, however, that the “main limitation is the small numbers of observations within certain subgroups, such as specific biologic exposures or participants in ethnic minority groups, restricting generalizability of our findings and the interpretation of some subgroup analyses.”

Moreover, the small number of paradoxical eczema events seen may have resulted in imprecise effect estimates, they observe, noting that the number of exposures to IL-23 inhibitors was low compared with other classes.

“Future studies with more exposures and paradoxical eczema events would enable a more robust analysis of individual drugs and patient subgroups,” the authors concluded.

The study was funded by the Medical Research Council. BADBIR is coordinated by The University of Manchester, and funded by the British Association of Dermatologists (BAD). The BAD receives income from AbbVie, Almirall, Amgen, Celgene, Janssen, LEO Pharma, Lilly, Novartis, Samsung Bioepis, Sandoz Hexal AG, and UCB Pharma for providing pharmacovigilance services. This income finances a separate contract between the BAD and The University of Manchester, which coordinates BADBIR. Mr. Al-Janabi reported receiving grants from the Medical Research Council during the conduct of the study; nonfinancial support from UCB, Almirall, and Janssen; and personal fees from UCB outside the submitted work.

The BADBIR Study Group authors believe that, to the best of their knowledge, this is the first study to compare paradoxical eczema risk by biologic class. “Based on clinical experience and prevalence of eczematous reactions reported in some IL-17 inhibitor clinical trials, we suspected an association between IL-17 inhibitor exposure and paradoxical eczema,” they wrote.

“While the incidence of paradoxical eczema was numerically highest among IL-17 inhibitor exposures, it was not significantly different from the incidence among TNF inhibitor exposures.” The low overall incidence of paradoxical eczema “may be reassuring for patients and clinicians,” they added, “but it is possible that the incidence was underestimated due to underreporting or exclusion of adverse events with insufficient detail.”

Details of the Analysis, Other Findings

To explore the risk of paradoxical eczema by biologic class and identify possible risk factors, the BADBIR Study Group performed a prospective cohort study using data held within the BADBIR database between September 2007 and December 2022.

Adults over the age of 18 year or older with plaque psoriasis and who had been treated with at least one of the following biologics were eligible for inclusion: the TNF inhibitors adalimumab, certolizumab pegol, etanercept, and infliximab; the IL-17 inhibitors bimekizumab, brodalumab, ixekizumab, and secukinumab; the IL-12/23 inhibitor ustekinumab; and the IL-23 inhibitors guselkumab, risankizumab, and tildrakizumab.

Patient records and adverse event data were reviewed to determine the incidence of paradoxical eczema events, using terms such as eczema, eczematized, eczematous, atopy, atopic, and dermatitis.

Of 24,952 drug exposures analyzed, the majority (11,819) were for TNF inhibitors, followed by IL-17 inhibitors (4,776), IL-12/23 inhibitors (6,423), and finally, IL-23 inhibitors (1,934).

Mr. Al-Janabi and coauthors reported that the median time to onset of paradoxical eczema events was 294 days — approximately 9.8 months. The earliest that these events were recorded was at 120 days (4 months), and the latest at 699 days (almost 2 years).

The face and neck were the most common sites affected (26% of exposures), with other sites including the limbs (23%), the trunk (13%), and hands or feet (12%). Itching (18%), redness (7%), and dryness (4%) were the most commonly reported symptoms.

The researchers noted that 21 patients had skin biopsies taken and “all showed spongiosis or a feature of eczema, with 1 having overlapping features of psoriasis.”

In the majority (92 %) of cases, patients experienced only one eczema event. Of the 20 patients who had more than one event, just over one-fifth of repeat events occurred after receiving the same biologic as for the index event. A quarter of events occurred after a different biologic of the same class had been used, and just over half of events occurred after a different class of biologic had been given.

Strengths and Limitations

The “large sample size and inclusion of multiple lines of exposure per participant” are strengths of the study, said the researchers. “We included data for all currently available biologics, originating from more than 160 dermatology centers in the UK and Ireland.”

They added, however, that the “main limitation is the small numbers of observations within certain subgroups, such as specific biologic exposures or participants in ethnic minority groups, restricting generalizability of our findings and the interpretation of some subgroup analyses.”

Moreover, the small number of paradoxical eczema events seen may have resulted in imprecise effect estimates, they observe, noting that the number of exposures to IL-23 inhibitors was low compared with other classes.

“Future studies with more exposures and paradoxical eczema events would enable a more robust analysis of individual drugs and patient subgroups,” the authors concluded.

The study was funded by the Medical Research Council. BADBIR is coordinated by The University of Manchester, and funded by the British Association of Dermatologists (BAD). The BAD receives income from AbbVie, Almirall, Amgen, Celgene, Janssen, LEO Pharma, Lilly, Novartis, Samsung Bioepis, Sandoz Hexal AG, and UCB Pharma for providing pharmacovigilance services. This income finances a separate contract between the BAD and The University of Manchester, which coordinates BADBIR. Mr. Al-Janabi reported receiving grants from the Medical Research Council during the conduct of the study; nonfinancial support from UCB, Almirall, and Janssen; and personal fees from UCB outside the submitted work.

Patients with psoriasis being treated with biologics have a low overall risk for developing the paradoxical symptoms of eczema, with interleukin (IL)-23 inhibitors found to confer the lowest risk of the drug classes examined in a large observational analysis.

Using data from the British Association of Dermatologists Biologics and Immunomodulators Register (BADBIR) database, Ali Al-Janabi, MA, from the University of Manchester (England) and associates found that 273 (1%) of approximately 25,000 drug exposures in 13,699 biologic-treated patients with psoriasis were associated with paradoxical eczema.

The incidence of paradoxical eczema was found to vary by class. The highest rate was seen for IL-17 inhibitors, at 1.22 per 100,000 person-years, and the lowest rate was seen with IL-23 inhibitors, at 0.56 per 100,000 person-years. The respective incidence rates for tumor necrosis factor (TNF) inhibitors and IL-12/IL-23 inhibitors were a respective 0.94 and 0.80 per 100,000 person-years.

“Compared with TNF inhibitors, IL-23 inhibitor exposure was associated with significantly lower risk of paradoxical eczema,” the BADBIR Study Group reported in JAMA Dermatology. Indeed, patients treated with IL-23 inhibitors were 61% less likely than were those taking TNF-inhibitors to experience a paradoxical eczema event.

“These findings remained when restricting the analysis to first-line biologic exposures and were specific to this eczema phenotype” the group said.

Cautious Interpretation

As the corresponding author for the work, Mr. Al-Janabi observed in an email that the research needs to be replicated, and the findings need to be interpreted with caution.

“As well as usual clinical variables influencing biologic selection, clinicians could consider IL-23 inhibitors in patients with previous atopic dermatitis, hay fever, or paradoxical eczema episodes, as this class was associated with the lowest risk of paradoxical eczema,” he suggested.

A prior history of atopic dermatitis (AD) and hay fever appears to be particularly relevant, as both substantially upped the chances that paradoxical eczema would occur, with hazard ratios of 12.40 and 3.78, respectively. Increasing age also increased the risk, albeit slightly (hazard ratio [HR], 1.02 per year), and there was an apparent lower risk (HR, 0.60) comparing men and women.

Lebrikizumab, an investigational interleukin-13 inhibitor, showed significant efficacy compared with placebo across racial and ethnic subgroups in patients with moderate-to-severe atopic dermatitis.

The finding comes from an analysis of the 16-week induction periods of the phase 3 ADvocate1 and ADvocate2 trials, which Raj Chovatiya, MD, PhD, presented during a late-breaking abstract session at the Revolutionizing Atopic Dermatitis (RAD) Virtual Conference. The efficacy of lebrikizumab monotherapy to treat moderate-to-severe AD has been established in phase 3 studies, “but disease characteristic and efficacy outcomes may vary among racial and ethnic subgroups,” said Dr. Chovatiya, assistant professor in the department of dermatology at Northwestern University, Chicago. “The goal of the current study is to report the week 16 efficacy of lebrikizumab-treated patients in racial and ethnic subgroups from ADvocate1 and ADvocate2.”

Dr. Chovatiya

Key eligibility criteria for both trials included adults or adolescents with a diagnosis of AD as defined by the American Academy of Dermatology Consensus Criteria, for at least 1 year prior to screening. They had moderate-to-severe AD, were candidates for systemic therapy, and were dupilumab- and tralokinumab-naive. Outcomes of interest were the Investigator’s Global Assessment 0 or 1, with at least a 2-point improvement; and the proportions of patients who achieved Eczema Area and Severity Index (EASI75) and EASI90 responses, and an improvement of 4 points or more on the Pruritus Numeric Rating Scale (NRS).

For statistical analysis, the researchers pooled data from Advocate1 and Advocate2 and applied imputation methodology to the 16-week induction period. Subsequent data from patients who received topical or systemic rescue medication or discontinued treatment due to lack of efficacy were imputed as nonresponders. Subsequent data from patients who discontinued treatment for other reasons were set to missing, and the researchers handled missing data with multiple imputation. They used logistic regression to test the interaction between the treatment and subgroup and the Cochran-Mantel-Haenszel method to evaluate the treatment effect within each subgroup after adjusting for stratification factors.

Dr. Chovatiya reported findings from the 851 study participants in the combined studies. Of these, 542 were White, 192 were Asian, 84 were Black, and 33 were from other racial subgroups. By ethnic subgroup, 748 were not Hispanic or Latino, 91 were Hispanic or Latino, and ethnicity was unknown or not reported for 12 subjects. At baseline, the mean body mass index was slightly higher among Blacks (30.4 kg/m²) and Hispanics (29.4 kg/m²) compared with other racial and ethnic groups, “which reflects general epidemiologic data among these groups in the United States,” Dr. Chovatiya said. “You can also see a difference in the balance of IGA scores — they were a little bit more severe in the Black or African American and Hispanic groups as well.” The researchers also observed differences in the baseline EASI score across some of these groups, particularly in the Asian individuals, who had higher EASI scores. Prior use of systemic therapy was lower in the Black and “other” subgroups, compared with other racial subgroups.

At week 16, key efficacy endpoints were generally similar between the different racial subgroups. Specifically, 25.1% of Asians in the lebrikizumab treatment group achieved an IGA of 0/1, compared with 4.1% of those in the placebo group (P < .001), while 33.2% of Blacks in the lebrikizumab treatment group achieved an IGA of 0/1, compared with 13.2% of those in the placebo group (no P value was established because this subgroup represented less than 10% of the entire study population). In addition, 43.3% of Whites in the lebrikizumab treatment group achieved an IGA of 0/1, compared with 14.1% of those in the placebo group (P < .001).

In other findings, 45.5% of Asians in the lebrikizumab treatment group achieved an EASI75, compared with 8.5% of those in the placebo group (P < .001), while 51.7% of Blacks in the lebrikizumab treatment group achieved an EASI75, compared with 18.8% of those in the placebo group. Among whites in the lebrikizumab treatment group, 59.7% of achieved an EASI75, compared with 20.4% of those in the placebo group (P < .001).

Dr. Chovatiya said that 26.5% of Asians in the lebrikizumab treatment group achieved an EASI90, compared with 4.3% of those in the placebo group (P < .001), while 26.9% of Blacks in the lebrikizumab treatment group achieved an EASI90, compared with 13.2% of those in the placebo group. In addition, 38.3% of Whites in the lebrikizumab treatment group achieved an EASI90, compared with 10.9% of those in the placebo group (P < .001).

Finally, 36.4% of Asians in the lebrikizumab treatment group achieved a 4-point or greater improvement on the NRS, compared with 5.7% of those in the placebo group (P <. 001), while 41.7% of Blacks in the lebrikizumab treatment group achieved a 4-point or greater improvement on the NRS, compared with 17.4% of those in the placebo group. In addition, 45.9% of Whites in the lebrikizumab treatment group achieved a 4-point or greater improvement on the NRS, compared with 14.8% of those in the placebo group (P < .001). Statistical analyses of efficacy endpoints conducted by ethnic group yielded similar results.

Dr. Chovatiya acknowledged certain limitations of the study, including the fact that differences in baseline demographics and disease characteristics limit direct comparison across racial and ethnic subgroups. “Due to the relatively small sample size of some racial and ethnic subgroups and the post hoc nature of this analysis, additional studies are needed to verify these results,” he concluded. But for now, he said, the data available indicate that “lebrikizumab is effective across racial and ethnic subgroups for the treatment of moderate-to-severe AD after 16 weeks of monotherapy treatment.”

The study was funded by Dermira, a wholly owned subsidiary of Eli Lilly and Company. Dr. Chovatiya disclosed that he is speaker for and/or a consult and advisory board member to many pharmaceutical companies, including Eli Lilly.

A significant number of patients with moderate-to-severe atopic dermatitis (AD) failed to achieve adequate disease control with systemic therapies over 12 months in a study of patient registry data, indicating a substantial degree of “therapeutic inertia,” the study’s lead author, Jonathan I. Silverberg, MD, PhD, MPH, reported.

The findings come from an analysis of real-world outcomes from the TARGET-DERM AD registry, which Dr. Silverberg, professor and director of clinical research and contact dermatitis in the department of dermatology at George Washington University, Washington, presented during a late-breaking abstract session at the Revolutionizing Atopic Dermatitis (RAD) Virtual Conference. He characterized the findings as “patients just getting stuck with a therapy and not advancing when they need to.”

TARGET-DERM AD is a longitudinal observational study of people with AD at 39 academic centers in the United States and Canada. Dr. Silverberg and his coinvestigators evaluated the proportion of patients who were experiencing an inadequate response after receiving systemic therapy and continuing on the same treatment for 3-12 months. “These are patients who are receiving their first or advanced systemic therapy, and the question is, how long did they stay on it, even if they’re not doing so well?” Dr. Silverberg said.

The researchers identified and compared the proportions of patients not achieving moderate or optimal clinician-reported outcome targets on patients with AD treated with their first systemic therapy. Advanced systemic therapy (AST) included abrocitinib, dupilumab, tralokinumab, or upadacitinib, while conventional systemic therapy (CST) included methotrexate, cyclosporine, mycophenolate mofetil, azathioprine, and systemic corticosteroids.

Patients in TARGET-DERM AD were treated and maintained on their first systemic therapy (either advanced or conventional) for up to 12 months. They had a validated Investigator’s Global Assessment of AD (vIGA-AD) score of 3 or 4 less than 45 days prior to initiation of systemic therapy or up to 14 days afterward. They also had at least one vIGA-AD assessment 3-12 months after initiating treatment. Outcome measures included IGA (defined as a score of 2 or less, with an optional target of 0 or 1), BSA (defined as a 50% BSA improvement, with an optimal target BSA of 2% or less), and the Worst-Itch Numeric Rating Scale (defined as at least a 4-point reduction, with an optimal target of 1 or less).

The analysis included 445 patients with a mean age of 31 years at enrollment. More than half (62%) were female and 45% were non-Hispanic Whites. Most patients (92%) were on an AST, mainly dupilumab, with smaller proportions treated with either tralokinumab, upadacitinib, or abrocitinib. Fewer than 10% of patients in the registry were being treated with CSTs.

At 6 months, 37% and approximately 67% of the AST-treated patients had inadequate responses in terms of skin clearance and itch outcomes, respectively. At 12 months, these figures were about 30% and 66%, respectively. CST-treated patients showed a similar trend. For patients starting an AST on or after Sept. 21, 2021, when three additional AST options were available (tralokinumab, upadacitinib, and abrocitinib), the proportion of patients demonstrating an adequate response over 12 months was generally similar to the overall cohort of those on ASTs.

“These findings suggest a need for alternative therapies and management strategies in AD treatment,” concluded Dr. Silverberg, who chaired the RAD symposium.

A significant number of patients with moderate-to-severe atopic dermatitis (AD) failed to achieve adequate disease control with systemic therapies over 12 months in a study of patient registry data, indicating a substantial degree of “therapeutic inertia,” the study’s lead author, Jonathan I. Silverberg, MD, PhD, MPH, reported.

The findings come from an analysis of real-world outcomes from the TARGET-DERM AD registry, which Dr. Silverberg, professor and director of clinical research and contact dermatitis in the department of dermatology at George Washington University, Washington, presented during a late-breaking abstract session at the Revolutionizing Atopic Dermatitis (RAD) Virtual Conference. He characterized the findings as “patients just getting stuck with a therapy and not advancing when they need to.”

TARGET-DERM AD is a longitudinal observational study of people with AD at 39 academic centers in the United States and Canada. Dr. Silverberg and his coinvestigators evaluated the proportion of patients who were experiencing an inadequate response after receiving systemic therapy and continuing on the same treatment for 3-12 months. “These are patients who are receiving their first or advanced systemic therapy, and the question is, how long did they stay on it, even if they’re not doing so well?” Dr. Silverberg said.

The researchers identified and compared the proportions of patients not achieving moderate or optimal clinician-reported outcome targets on patients with AD treated with their first systemic therapy. Advanced systemic therapy (AST) included abrocitinib, dupilumab, tralokinumab, or upadacitinib, while conventional systemic therapy (CST) included methotrexate, cyclosporine, mycophenolate mofetil, azathioprine, and systemic corticosteroids.

Patients in TARGET-DERM AD were treated and maintained on their first systemic therapy (either advanced or conventional) for up to 12 months. They had a validated Investigator’s Global Assessment of AD (vIGA-AD) score of 3 or 4 less than 45 days prior to initiation of systemic therapy or up to 14 days afterward. They also had at least one vIGA-AD assessment 3-12 months after initiating treatment. Outcome measures included IGA (defined as a score of 2 or less, with an optional target of 0 or 1), BSA (defined as a 50% BSA improvement, with an optimal target BSA of 2% or less), and the Worst-Itch Numeric Rating Scale (defined as at least a 4-point reduction, with an optimal target of 1 or less).

The analysis included 445 patients with a mean age of 31 years at enrollment. More than half (62%) were female and 45% were non-Hispanic Whites. Most patients (92%) were on an AST, mainly dupilumab, with smaller proportions treated with either tralokinumab, upadacitinib, or abrocitinib. Fewer than 10% of patients in the registry were being treated with CSTs.

At 6 months, 37% and approximately 67% of the AST-treated patients had inadequate responses in terms of skin clearance and itch outcomes, respectively. At 12 months, these figures were about 30% and 66%, respectively. CST-treated patients showed a similar trend. For patients starting an AST on or after Sept. 21, 2021, when three additional AST options were available (tralokinumab, upadacitinib, and abrocitinib), the proportion of patients demonstrating an adequate response over 12 months was generally similar to the overall cohort of those on ASTs.

Tape stripping, which allows sampling of the epidermis to the midgranular layer, is a valid, minimally invasive way to identify cutaneous biomarkers in patients with hidradenitis suppurative (HS), results from a novel study showed.

“Tape strips can provide important clues to when and which drugs to use in HS in patients with both early and late disease, which can change clinical practice,” corresponding study author Emma Guttman-Yassky, MD, PhD, professor and chair of dermatology at the Icahn School of Medicine at Mount Sinai in New York City, said in an interview. “It is noninvasive and nonscarring,” she added.

Tape stripping has been validated in atopic dermatitis, psoriasis, and other dermatologic conditions in recent years. For the current study, which was published online in the Journal of the American Academy of Dermatology, and is believed to be the first of its kind, Dr. Guttman-Yassky and colleagues performed RNA sequencing from large D-Squame tape strips collected from lesional and nonlesional skin of 22 patients with HS and from 21 age- and sex-matched healthy controls. They correlated the expression of skin biomarkers between tape strips and a previously published gene-signature of HS biopsies. The mean age of patients with HS was 43 years, while the mean age of healthy controls was 35. The average International Hidradenitis Suppurativa Severity Score System (IHS4) score of the HS cohort was 36.

Consistent with published studies, the researchers found that tape strips identified an overall higher inflammatory burden in HS. Specifically, they observed an upregulation of known cytokines within the following pathways: Th1 (such as IFNG, CXCL9/10/11, and CCR5); Th17 (such as interleukin [IL]-17A/F, IL12B, IL23A, CAMP, and CCL20); Th2 (such as IL4R, IL13/IL31/IL10, CCR4, CCL7/CCL13/CCL24, TNFSF4/OX40L, and TNFRSF4/OX40); and Th22 (such as IL22 and IL32).

The researchers also found that the expression of Th17 and tumor necrosis factor (TNF)–alpha pathways were highly correlated between tape strips and biopsies and that HS clinical severity was significantly associated with expression of biomarkers, such as TNF-alpha, IL17A/F, OX40, JAK1-3, and IL4R in HS lesional and/or nonlesional skin.

“It was quite unexpected that we are able to identify, using a minimally invasive approach that samples only the upper layers of the epidermis, products and processes that are considered to be deeper-situated, such as IL-17, and other immune markers,” Dr. Guttman-Yassky said in the interview. “We were also surprised to see how well the tape-stripped–derived skin molecular profile correlated with that of biopsies, as well as how well it correlated with the clinical disease severity of HS.”

Also surprising, she added, was that the biomarkers in nonlesional tape-stripped skin, such as IL-17 and TNF alpha, “show high correlations with disease severity and provide clues to early disease.”

If using tape strips in HS is validated in larger cohort studies, the potential cost implications of using this approach in practice remain unclear, Dr. Guttman-Yassky said. “It is currently not cheap, but we are hoping that one day, we can provide a means to diagnose the disease and treat it early, and appropriately, utilizing this approach,” she commented. “We are excited about the applicability of this study to the early treatment and longitudinal follow up of HS with drugs that are targeting specific immune molecules and pathways,” she said, adding that it will also be useful for helping determine which drug should be used for which patient.

She and her co-authors acknowledged certain limitations of the study, including its small sample size and the fact that tape stripping is limited to the epidermis.

Asked to comment on the study, Jennifer L. Hsiao, MD, a dermatologist who directs the HS clinic at the University of Southern California, Los Angeles, said the findings “have important potential implications for our ability to one day personalize treatments for a patient with early HS in a minimally invasive way.”

As the study authors point out, she added, “tape strips only allow sampling of the epidermis, which is limiting in a disease like HS where much of the disruption is in the dermis with deep nodules and dermal tunnels. However, our overall goal should be to catch patients in the early stages of their disease before the occurrence of irreversible tissue damage such as dermal tunnels. Thus, the ongoing campaign for early diagnosis and early intervention by various stakeholders in the field of HS can help mitigate the impact of this inherent limitation of tape strips. It will be exciting to see larger studies that investigate tape strip results in relation to clinical phenotypes, disease progression, and therapeutic responses.”

The study was funded by an International Dermatology Outcome Measures Hidradenitis Suppurativa Grant. Dr. Guttman-Yassky disclosed that she has been a consultant to, an adviser for, and has received research grants from many pharmaceutical companies. Of the remaining authors, 2 also had multiple disclosures and 11 had no disclosures. Dr. Hsiao disclosed that she is a member of the board of directors for the Hidradenitis Suppurativa Foundation. She has also served as a consultant for AbbVie, Aclaris, Boehringer Ingelheim, Incyte, Novartis, and UCB; as a speaker for AbbVie; and as an investigator for Amgen, Boehringer Ingelheim, and Incyte.

Atopic dermatitis (AD) is an inflammatory skin condition that affects approximately 16.5 million adults in the United States.¹ Atopic dermatitis is associated with skin barrier dysfunction and the activation of type 2 inflammatory cytokines. Multiorgan involvement of AD has been demonstrated, as patients with AD are more prone to asthma, allergic rhinitis, and other systemic diseases.² In 2020, Smirnova et al³ reported a significant association (adjusted odds ratio [AOR], 1.58; 95% CI, 1.30-1.92) between AD and chronic obstructive pulmonary disease (COPD) in a large Swedish population. Currently, there is a lack of research evaluating the association between AD and COPD in a population of US adults. Therefore, we explored the association between AD and COPD (chronic bronchitis or emphysema) in a population of US adults utilizing the 1999-2006 National Health and Nutrition Examination Survey (NHANES), as these were the latest data for AD available in NHANES.⁴

We conducted a population-based, cross-sectional study focused on patients 20 years and older with psoriasis from the 1999-2006 NHANES database. Three outcome variables—emphysema, chronic bronchitis, and COPD—and numerous confounding variables for each participant were extracted from the NHANES database. The original cohort consisted of 13,134 participants, and 43 patients were excluded from our analysis owing to the lack of response to survey questions regarding AD and COPD status. The relationship between AD and COPD was evaluated by multivariable logistic regression analyses utilizing Stata/MP 17 (StataCorp LLC). In our logistic regression models, we controlled for age, sex, race/ethnicity, education, income, tobacco usage, diabetes mellitus and asthma status, and body mass index (eTable).

Our study consisted of 13,091 participants. Multivariable logistic regressions were utilized to examine the association between AD and COPD (Table). Approximately 12.5% (weighted) of the patients in our analysis had AD. Additionally, 9.7% (weighted) of patients with AD had received a diagnosis of COPD; conversely, 5.9% (weighted) of patients without AD had received a diagnosis of COPD. More patients with AD reported a diagnosis of chronic bronchitis (9.2%) rather than emphysema (0.9%). Our analysis revealed a significant association between AD and COPD among adults aged 20 to 59 years (AOR, 1.43; 95% CI, 1.13-1.80; P=.003) after controlling for potential confounding variables. Subsequently, we performed subgroup analyses, including exclusion of patients with an asthma diagnosis, to further explore the association between AD and COPD. After excluding participants with asthma, there was still a significant association between AD and COPD (AOR, 1.57; 95% CI, 1.14-2.16; P=.007). Moreover, the odds of receiving a COPD diagnosis were significantly higher among male patients with AD (AOR, 1.54; 95% CI, 1.06-2.25; P=.03).

Our results support the association between AD and COPD, more specifically chronic bronchitis. This finding may be due to similar pathogenic mechanisms in both conditions, including overlapping cytokine production and immune pathways.⁵ Additionally, Harazin et al⁶ discussed the role of a novel gene, collagen 29A1 (COL29A1), in the pathogenesis of AD, COPD, and asthma. Variations in this gene may predispose patients to not only atopic diseases but also COPD.⁶

Limitations of our study include self-reported diagnoses and lack of patients older than 59 years. Self-reported diagnoses could have resulted in some misclassification of COPD, as some individuals may have reported a diagnosis of COPD rather than their true diagnosis of asthma. We mitigated this limitation by constructing a subpopulation model with exclusion of individuals with asthma. Further studies with spirometry-diagnosed COPD are needed to explore this relationship and the potential contributory pathophysiologic mechanisms. Understanding this association may increase awareness of potential comorbidities and assist clinicians with adequate management of patients with AD.

Our analysis revealed a significant association between AD and COPD among adults aged 20 to 59 years (AOR, 1.43; 95% CI, 1.13-1.80; P=.003) after controlling for potential confounding variables. Subsequently, we performed subgroup analyses, including exclusion of patients with an asthma diagnosis, to further explore the association between AD and COPD. After excluding participants with asthma, there was still a significant association between AD and COPD (AOR, 1.57; 95% CI, 1.14-2.16; P=.007). Moreover, the odds of receiving a COPD diagnosis were significantly higher among male patients with AD (AOR, 1.54; 95% CI, 1.06-2.25; P=.03).

Our results support the association between AD and COPD, more specifically chronic bronchitis. This finding may be due to similar pathogenic mechanisms in both conditions, including overlapping cytokine production and immune pathways.⁵ Additionally, Harazin et al⁶ discussed the role of a novel gene, collagen 29A1 (COL29A1), in the pathogenesis of AD, COPD, and asthma. Variations in this gene may predispose patients to not only atopic diseases but also COPD.⁶

Limitations of our study include self-reported diagnoses and lack of patients older than 59 years. Self-reported diagnoses could have resulted in some misclassification of COPD, as some individuals may have reported a diagnosis of COPD rather than their true diagnosis of asthma. We mitigated this limitation by constructing a subpopulation model with exclusion of individuals with asthma. Further studies with spirometry-diagnosed COPD are needed to explore this relationship and the potential contributory pathophysiologic mechanisms. Understanding this association may increase awareness of potential comorbidities and assist clinicians with adequate management of patients with AD.

TOPLINE:

The use of low-dose methotrexate among older adults with chronic kidney disease (CKD) was associated with a significantly increased risk at 90 days for serious adverse events requiring a hospital visit, compared with starting treatment with hydroxychloroquine.

METHODOLOGY:

• In a retrospective, population-based cohort study conducted in Ontario, researchers used linked administrative healthcare data to identify adults aged 66 years and older with CKD who were not undergoing dialysis and were new to medication; CKD was defined as an estimated glomerular filtration rate (eGFR) of less than 60 mL/min per 1.73 m².
• The study population included 2,309 individuals who began treatment with low-dose methotrexate (5-35 mg/week); they were matched with 2,309 individuals who began treatment with hydroxychloroquine (200-400 mg/day). The median age was 76 years, 69% were women, and rheumatoid arthritis was the most common diagnosis (56%).
• The primary outcome was the risk of a hospital visit at 90 days for a composite of serious adverse events that included myelosuppression, sepsis, pneumotoxic effects, or hepatoxic effects.

TAKEAWAY:

• Overall, 3.55% of methotrexate patients and 1.73% of hydroxychloroquine patients met the primary outcome (risk ratio, 2.05); these events occurred at a median of 49 days and 43 days after starting the medications for the two groups, respectively.
• In an analysis by eGFR category, the risk of serious adverse events at 90 days increased among patients with eGFR levels less than 45 mL/min per 1.73 m² (RR, 2.79).
• In a secondary comparison, the 90-day risk of serious adverse events was higher among methotrexate patients who began treatment with doses of 15-35 mg/week in comparison with those whose initial doses were 5 to less than 15 mg/week.

IN PRACTICE:

“Patients with CKD starting low-dose methotrexate should have active surveillance, including blood tests and chest radiographs performed regularly to monitor for signs of myelosuppression, infection, hepatotoxic effects, and pneumotoxic effects,” the researchers wrote.

SOURCE:

The lead author on the study was Flory T. Muanda, MD, of Western University, London, Ont. The study was published online in JAMA Network Open.

LIMITATIONS:

The observational design and lack of data on patients’ adherence to medications were among the limiting factors, as were the focus on older adults with CKD and the lack of assessment of the risk-benefit ratio of low-dose methotrexate.

DISCLOSURES:

The study was supported by the Institute for Clinical Evaluative Sciences. Dr. Muanda had no financial conflicts to disclose.
