AMSTERDAM — For patients with atopic dermatitis (AD) who responded to the anti–interleukin (IL)–13 monoclonal antibody lebrikizumab in the pivotal trials, the level of response, including 90% skin clearance, has generally remained unchanged among those followed up for an additional 2 years, according to the latest data from an extension study. 

At the end of the maintenance phase of the pivotal trials at 12 months, 84% of the patients enrolled into the extension had clear or almost clear skin, as per the Investigator Global Assessment (IGA). This overall figure as well as the proportion with even better responses have persisted unchanged, reported Diamant Thaçi, MD, PhD, professor and head of the Comprehensive Center for Inflammatory Medicine, University of Lübeck in Germany. 
 

Responses at 3 Years Maintained

“This is really quite remarkable,” Dr. Thaçi said. “Roughly all the patients maintained their response.” These results became even more remarkable when patients were assessed for their use of adjunctive therapy to control flares. 

“Over the whole follow-up, 90% had no need for topical corticosteroids or any other rescue therapy,” Dr. Thaçi reported, providing data from the ADjoin lebrikizumab extension study during a late-breaking news session at the annual meeting of the European Academy of Dermatology and Venereology. 

The patients in ADjoin were enrolled from the pivotal phase 3 ADvocate 1 and 2 trials completed almost 2 years ago and published together in March 2023. Lebrikizumab was approved in the United States in September 2024 for moderate to severe AD in patients aged ≥ 12 years, following previous approvals in Europe in 2023 and in Japan in January 2024.

In these two identical trials with a total of 564 patients, the primary endpoint was an IGA of 0 or 1, signifying clear or almost clear skin. At nearly 40%, the proportion of patients reaching this outcome at 16 weeks was about threefold greater (P < .001) on lebrikizumab than on placebo. The benefit was similar on secondary endpoints, such as 75% improvement in the Eczema Area and Severity Index (EASI75) score. 

At the end of the double-blind, placebo-controlled 16-week phase of the ADvocate 1 and 2 trials, which enrolled adults and adolescents aged ≥ 12 years, responders were enrolled into a maintenance phase in which they were rerandomized to 250 mg lebrikizumab every 2 weeks (Q2W) or every 4 weeks (Q4W). The latter is the approved maintenance dose. 

At the end of the maintenance phase, which lasted another 32 weeks (total exposure of 52 weeks for those initially randomized to lebrikizumab), patients were invited into the ADjoin extension. The only exclusions from the extension were serious adverse events related to lebrikizumab and noncompliance. 
 

Response Curves Appear as Straight Lines

Over the next 2 years of ADjoin, response curves appeared as straight lines not only for the overall response but when patients were stratified for different levels of response at the extension study entry. Specifically, 81.5% and 83.3% had an IGA score of 0 or 1 in the Q2W and Q4W arms at completion of the ADvocate 16-week double-blind phase. At 3 years, the rates were 84.0% and 82.9%, respectively. 

For the subgroup who entered ADjoin with an EASI75 or an EASI90 response, the persistence of this level of response over 2 years was similar, although there was some gain observed among those who entered the trial with an EASI75 response. 

“Not only did these patients maintain their response, but the response on average slowly improved, so that there were more patients with an EASI90 response at the 3-year timepoint,” Dr. Thaçi said.

Of the 181 patients in the ADjoin extension, 82 patients were maintained on Q2W dosing and 99 were maintained on Q4W lebrikizumab. Their mean age was about 35 years, more than half were women, and nearly 40% had severe AD at the time they enrolled in the ADvocate trials. There was essentially no difference in response rates among those in the Q2W and Q4W arms over time in ADjoin. 
 

Side Effect Profile Essentially Unchanged

The side effect and tolerability profiles, which were favorable in the original 16-week placebo-controlled study, have remained unchanged over the subsequent maintenance phase and through the additional 2 years of the ADjoin extension.

“There continued to be reports of conjunctivitis, which is very specific for anti–IL-13 therapies,” Dr. Thaçi said. However, he said that the incidence did not increase over time, and because it was easy to treat, “most patients do not discontinue lebrikizumab for this reason.” Moreover, he said the impression was that “the number of patients experiencing adverse effects has been decreasing over time.” 

Calling these long-term results “very exciting,” Dr. Thaçi called lebrikizumab “a very valuable option for long-term AD care.” 

Asked for his perspective on the results, Jonathan I. Silverberg, MD, PhD, Director of Clinical Research, Department of Dermatology, George Washington University, Washington, DC, said that it is important to study long-term efficacy, and these results are positive. Without direct comparisons to other biologics available for AD, nothing can be implied about the relative efficacy of monoclonal antibodies approved for AD. 

“These data are important both from an efficacy and safety perspective” for those advising patients who need chronic AD treatment, said Dr. Silverberg, who was the principal investigator of the ADvocate trials. 

Earlier this year, 5-year follow-up data were published for dupilumab. Of 326 patients who remained on therapy this long, 220 (67%) maintained an IGA of 0 or 1 at the end of the study. There were no unexpected adverse events, which were generally stable or declined throughout the study. 

Dr. Thaçi has financial relationships with AbbVie, Amgen, Boehringer Ingelheim, Bristol-Myers Squibb, Celltrion, Galderma, Leo Pharma, L’Oreal, Janssen-Cilag, New Bridge, Novartis, Pfizer, Regeneron, Roche, Sanofi, Sun Pharma, UCB, and Vichy. Dr. Silverberg reported financial relationships with more than 40 pharmaceutical companies including those that make drugs for AD.

AMSTERDAM — For frontal fibrosing alopecia (FFA), a disease with no approved therapies, topical delgocitinib attenuated inflammation and generated hair regrowth in women in a controlled phase 2a trial.

“This is an exciting avenue for FFA if the data are recapitulated in a larger population. It could be an important new treatment option,” said Maryanne Senna, MD, director at Lahey Hospital & Medical Center’s Hair Loss Center of Excellence, Burlington, Massachusetts, and assistant dermatology professor at Harvard Medical School, Boston, Massachusetts.

In a design characterized as “exploratory,” the trial had two parts: a randomized, double-blind, vehicle-controlled intervention for 12 weeks, followed by an open-label extension of topical delgocitinib for all participants for another 12 weeks. 

The primary efficacy endpoint was change in the molecular signature of FFA inflammation at 12 weeks. Clinical improvement was monitored with both trichoscopic images capturing the numbers of hairs and follicular units at 12 weeks and clinical severity scores through week 24. In a topical cream formulation, the Janus kinase inhibitor (JAKi) delgocitinib was associated with favorable activity for both. 
 

Some Hair Regrowth for All

“At 24 weeks, all patients achieved some degree of hair regrowth and a stabilization of disease based on hairline measurements,” Senna reported in a late-breaking news session at the 2024 European Academy of Dermatology and Venereology (EADV) Congress. 

On the clinical endpoints, Senna noted an upward trajectory in clinical improvement at the completion of the study.

The 30 participants were randomly assigned in a 1:1 ratio to receive delgocitinib cream in a concentration of 20 mg/g or vehicle cream applied twice daily for 12 weeks. At the end of this double-blind period, patients on vehicle were crossed over to the active therapy, and all patients were monitored for another 12 weeks in an open-label extension. 

The change from baseline in FFA biomarkers was selected as the primary endpoint based on previous work showing up-regulation in the expression of the Th1 biomarkers CXCL9, CXCL10, and interferon gamma in lesional vs nonlesional scalp in patients with FFA. 

When biopsies at the end of 12 weeks in the double-blind phase of the study were compared with the baseline biopsies, researchers found a decrease in expression of the three local inflammation markers in all patients receiving the JAKi, but not in those receiving the vehicle cream. In this small patient sample, only the reduction in expression of CXCL9, a cytokine known for differentiation and promotion of leukocytes, reached statistical significance (P < .05).

But in an analysis involving the expression of multiple genes, “lesions treated with delgocitinib had a 4% improvement in normalization toward a nonlesional transcriptomic profile, while patients treated with vehicle had a 33% worsening,” Senna reported. The difference was highly significant (P < .001).

Furthermore, the decrease in total Lichen Planopilaris Activity Index and FFA severity scores were numerically and statistically greater (P = .023) in the active-treatment arm than in the vehicle arm by the end of the double-blind part of the trial, she said.

On trichoscopy, there was an increased number of hairs and follicular units at 12 weeks relative to baseline among those treated with topical delgocitinib but a reduction in those treated with vehicle.
 

JAKi Patients Gained Hair, Vehicle Patients Lost Hair

On the basis of hair count per square centimeter from baseline, delgocitinib-treated patients gained on average of seven hairs whereas vehicle recipients lost an average of 11 hairs at 24 weeks, Senna reported.

Patients originally treated with vehicle did improve in most outcome measures in the open-label extension of the experimental treatment after crossover, but they did not catch up to those initially randomized to delgocitinib because of further accrual of favorable changes in the active-treatment group over time.

“There were no adverse events associated with active therapy or vehicle, including application-site reactions,” Senna said. The one between-group difference was a higher rate of COVID-19, but this was greater in the control arm.

All 30 of the participants in this study were women, and all had moderate to severe disease at enrollment. The median age was 64 years. Because of the predominant population at the hair loss center, all but one of the participants were White, and one participant was Asian. 

Characterizing FFA as “devastating and disfiguring,” Senna, who specializes in the care of alopecia, noted that this a difficult disease to control with the off-label strategies that are now used. The slow progress to identify treatments for FFA is illustrated by the fact that only one other double-blind and randomized trial has ever been conducted in FFA, she said.
 

Exploratory Study Supports Anecdotal Experience

On the basis of prior anecdotal experience with JAKi treatment for FFA, Senna said, “I do think that it is possible to get largely clear skin with this therapy.” However, she is now hoping for definitive trials to better characterize the efficacy and safety of oral and topical therapies, perhaps used sequentially to maintain clinical improvement.

In light of the limited current options, Menno de Rie, MD, PhD, professor of dermatology at the University of Amsterdam in the Netherlands, called these data “very inspiring and hopeful.” He suggested the promise of this therapy was reinforced by the upward trajectory of the biomarkers and clinical improvement over the study period. 

“Any improvement in treatment options would be welcome, because we do not [have] any reliable therapies for this condition,” de Rie, who was not an investigator, said in an interview after the presentation. 

Ultimately, Senna said, once effective therapy is established, the goal will be to start as early as possible in the disease process. She noted that there is evidence that prompt therapy can reverse the disorder, not just prevent progression.

“If you can get to the hair follicles before the point of no return, there is [a] chance [of] follicular rescue,” she said.

Delgocitinib cream (Anzupgo) was approved in Europe for treating chronic hand eczema in late September and is under review for the same indication in the United States. 

Senna has financial relationships with Arena, Concert, Eli Lilly, Pfizer, and Leo Pharma, which provided funding for this study. de Rie reported no potential conflicts of interest.

Furthermore, the decrease in total Lichen Planopilaris Activity Index and FFA severity scores were numerically and statistically greater (P = .023) in the active-treatment arm than in the vehicle arm by the end of the double-blind part of the trial, she said.

On trichoscopy, there was an increased number of hairs and follicular units at 12 weeks relative to baseline among those treated with topical delgocitinib but a reduction in those treated with vehicle.
 

JAKi Patients Gained Hair, Vehicle Patients Lost Hair

On the basis of hair count per square centimeter from baseline, delgocitinib-treated patients gained on average of seven hairs whereas vehicle recipients lost an average of 11 hairs at 24 weeks, Senna reported.

Patients originally treated with vehicle did improve in most outcome measures in the open-label extension of the experimental treatment after crossover, but they did not catch up to those initially randomized to delgocitinib because of further accrual of favorable changes in the active-treatment group over time.

“There were no adverse events associated with active therapy or vehicle, including application-site reactions,” Senna said. The one between-group difference was a higher rate of COVID-19, but this was greater in the control arm.

All 30 of the participants in this study were women, and all had moderate to severe disease at enrollment. The median age was 64 years. Because of the predominant population at the hair loss center, all but one of the participants were White, and one participant was Asian. 

Characterizing FFA as “devastating and disfiguring,” Senna, who specializes in the care of alopecia, noted that this a difficult disease to control with the off-label strategies that are now used. The slow progress to identify treatments for FFA is illustrated by the fact that only one other double-blind and randomized trial has ever been conducted in FFA, she said.
 

Exploratory Study Supports Anecdotal Experience

On the basis of prior anecdotal experience with JAKi treatment for FFA, Senna said, “I do think that it is possible to get largely clear skin with this therapy.” However, she is now hoping for definitive trials to better characterize the efficacy and safety of oral and topical therapies, perhaps used sequentially to maintain clinical improvement.

In light of the limited current options, Menno de Rie, MD, PhD, professor of dermatology at the University of Amsterdam in the Netherlands, called these data “very inspiring and hopeful.” He suggested the promise of this therapy was reinforced by the upward trajectory of the biomarkers and clinical improvement over the study period. 

“Any improvement in treatment options would be welcome, because we do not [have] any reliable therapies for this condition,” de Rie, who was not an investigator, said in an interview after the presentation. 

Ultimately, Senna said, once effective therapy is established, the goal will be to start as early as possible in the disease process. She noted that there is evidence that prompt therapy can reverse the disorder, not just prevent progression.

“If you can get to the hair follicles before the point of no return, there is [a] chance [of] follicular rescue,” she said.

Delgocitinib cream (Anzupgo) was approved in Europe for treating chronic hand eczema in late September and is under review for the same indication in the United States. 

Senna has financial relationships with Arena, Concert, Eli Lilly, Pfizer, and Leo Pharma, which provided funding for this study. de Rie reported no potential conflicts of interest.

AMSTERDAM — A proteomics study designed to determine why some patients with atopic dermatitis (AD) respond quickly to dupilumab, others respond more slowly, and the remainder do not respond at all demonstrated that molecular responses in these three groups are very different.

A discovery that could lead to personalizing therapies, the data identified “distinct systemic biomarker profiles,” according to Ester Del Duca, MD, an instructor in the Laboratory of Inflammatory Skin Diseases at the Icahn School of Medicine at Mount Sinai, New York City.

The study was conducted with 67 patients with AD and 16 healthy controls. Serum was collected at two timepoints: An average of 20 weeks after starting dupilumab, then at a mean interval of about 9 months later. At these timepoints, called follow-up 1 and 2, a panel of more than 600 proteins, including unique markers for immunologic, cardiovascular, and neurologic activity, were evaluated.

The criterion for differentiating the three response groups was an Investigator Global Assessment (IGA) score of 0 or 1, signifying clear or almost clear skin (or at least a 2-point IGA reduction from baseline). Early responders were those who met the criterion at both follow-ups, late responders were those who met this criterion only at the second follow-up, and nonresponders never met the criterion.

“There were no significant differences at baseline in clinical severity, past medical history, or patient characteristics,” said Del Duca, who presented these data in a late breaking news session at the European Academy of Dermatology and Venereology (EADV) 2024 Congress.

Of the 67 patients with AD, 39 were early responders, 11 were late responders, and 17 were nonresponders.

The differences in proteomics were marked. For early responders, there was an early normalization of the proteome, reported Del Duca, illustrating the differences in the proteome of the three groups with a color-coded chart of protein up-regulation and down-regulation relative to healthy controls. The normalization of the proteome persisted in early responders when assessed at the second follow-up.

In the late responders, the proteome dysregulation was substantial relative to healthy controls at the first follow-up, but there was considerable improvement by the second follow-up. Although the change at the second follow-up was still not as robust as that seen in the early responders at either follow-up, Del Duca described the proteomic profile as a 45% improvement from the first follow-up.

In contrast, nonresponders showed worsening in their blood proteome from follow-up 1 to 2. Nonresponders at first follow-up showed up-regulation relative to healthy controls for many proteins associated with the Th1 response, such as interferon gamma, CXCL9, and CXCL10, and Th2 response, such as interleukin-4 and Th17/22, and these did not normalize or worsen by the second follow-up.

“Uniquely to nonresponders, key Th1 biomarkers remained significantly up-regulated relative to controls at both follow-up 1 and 2,” with a P value < .05, Del Duca reported.

To achieve normalization of the proteome as defined by healthy controls, both up-regulation and down-regulation of protein activity were required, although more up-regulations than down-regulations were observed.

When evaluating the proteome changes most implicated in immunoregulation, the investigators were able to show a correlation between worsening in the proteome and greater severity of AD as defined by IGA, Eczema Area and Severity Index, and body surface area involvement.

“Spearman analysis revealed strong and positive correlations between improvements in biomarkers at follow-up 1 and 2 with improvements in clinical markers,” Del Duca said. As examples, she noted favorable changes in biomarkers specifically associated with T cells, dendritic cells, and natural killer cells as clinical outcomes improved.

Conversely, the worsening in T-cell activation among nonresponders, particularly Th1 biomarkers, also tracked with increasing AD symptoms over time.

The implications of the research are broad, and most importantly, it shows that therapeutic targets are likely to differ between patients with AD, according to Del Duca. Although proteomic studies have not yet been conducted with other treatments, these might provide further insight about how patients with AD differ in response across other drugs.

This is important work, according to Brigitte Dréno, MD, PhD, head of the Department of Dermatology, Nantes University Hospital in France. As moderator of the late-breaking news session, she suggested that there are many potential messages from these data, not least that treatment of AD likely involves targeting cytokines beyond those affected by dupilumab in at least some patients.

When Dréno asked Del Duca about what could be surmised about changes from baseline before treatment to the first follow-up, Del Duca said that the study was retrospective, so baseline data were not available.

This is an important missing piece of this investigation, according to Dréno.

“As you move this work forward,” she said that it would be “very important” to determine “if there are predictive markers for evaluating which patients will respond.”

This is a small study with many additional variables to consider in order to develop a clinically useful tool, Del Duca noted. However, this work not only has the potential to guide treatment selection but the biomarkers up-regulated in nonresponders are already “suggesting potential targets for refining therapeutic strategies,” she said.

The study received funding from Bristol-Myers Squibb. Del Duca reported no financial relationships with industry. Dréno reported financial relationships with La Roche–Posay, Pierre Fabré, and Galderma.

AMSTERDAM — Following the report of results from a randomized trial in which a topically applied Janus kinase (JAK) inhibitor was highly active in patients with mild to moderate hidradenitis suppurativa (HS), an open-label extension showed that 16 more weeks of treatment on as-needed basis provided complete or near complete clearance of lesions in up to 38.5% of patients.

“Ruxolitinib cream may be a novel approach to address an unmet medical need in the treatment of milder HS for which there are no currently approved treatments,” reported Martina L. Porter, MD, assistant professor of dermatology, Harvard Medical School, and Beth Israel Deaconess Medical Center, both in Boston, Massachusetts.

In the earlier 16-week, double-blind, randomized period of this phase 2b study, 69 adults with mild to moderate HS were randomized to 1.5% ruxolitinib cream or vehicle, applied twice daily for 16 weeks. The new results are from the open-label extension period, where those on the vehicle were crossed over to topical ruxolitinib and treatment was continued for another 16 weeks.
 

Over 80% Meet Primary Endpoint at 32 Weeks

Entry criteria for the study included Hurley stage I or II HS with no draining tunnels. Hurley stage III patients were not eligible. Patients had to have an abscess or inflammatory nodule (AN) count of 3 lesions concentrated in a single anatomic area or up to 10 lesions if disseminated. The median AN count of those enrolled was 5.4. 

In the randomized portion of the study and in the open-label extension, the recommendation for application was to apply the medication to nodules and a 1-cm area of surrounding skin. As-needed treatment was only recommended in the extension portion of the study and rescue medication was not allowed.

The goal of the open-label extension was to evaluate how long the improvements were sustained, according to Dr. Porter, who presented the results at the 2024 European Academy of Dermatology and Venereology (EADV) meeting.

The primary endpoints of AN50, signaling at least a 50% reduction in AN count from baseline, among those initially randomized to ruxolitinib cream climbed slightly from 79.2% at the end of 16 weeks to 81.0% at the end of 32 weeks.

This shows that the benefits recorded in the randomized phase of the trial were sustained during the open-label extension, Dr. Porter said. 

For those randomized to vehicle, there was a substantial response of 56.3% for AN50 during the randomized portion of the study, but catchup in the vehicle group to those on active therapy occurred rapidly over the open-label extension. By the end of 32 weeks, the score among the crossover patients slightly exceeded that of those on continuous therapy (88.5% vs 81.0%).

AN75 responses at week 32 were 66.7% and 61.5% in the continuous arm and crossover arm, respectively. The proportion of patients reaching an AN90 or AN100 response, meaning clear or almost clear, were 19% and 38.5%, in continuous treatment and crossover arms, respectively.

One of the secondary endpoints was the HS Clinical Response 50, indicating at least a 50% reduction in the AN count with no increase in abscesses or draining fistulae. At 32 weeks, the proportions of patients who met this endpoint were 81.0% and 88.5% in the continuous treatment and crossover arms, respectively. 

The mean reduction in International HS Severity Scoring System scores from baseline were 4.1 and 4.5 in the continuous treatment and crossover arms, respectively. 
 

Patients in the Study Mostly Women, 42% Black Individuals

Most (94%) of the participants were women; about 45% and 42% were White and Black individuals, respectively. Most of the remaining patients were Asian individuals. The median age at entry was 29 years, and the mean body mass index was approximately 34 kg/m². A substantial proportion of patients had systemic comorbidities, according to Dr. Porter, who noted that about 25% had anxiety, depression, or both.

“This phenotype — a high proportion of women with nodules but no draining tunnels and a substantial number of comorbidities — is one we often see in patients with mild HS,” Dr. Porter said.

The safety and tolerability profile of ruxolitinib cream was quite good, according to Dr. Porter, who noted that there were fewer treatment-related adverse events in the open-label extension. Overall, the number of treatment-related adverse events (3.6%), including application site reactions leading to discontinuation (1.8%) was low. 

Although there is a growing list of therapies now approved for HS, Dr. Porter emphasized that all have been developed for moderate to severe disease. She suggested that there is a sizable group of patients with mild disease for whom such therapies as biologics might not be warranted even if symptom relief is needed.

Given this unmet need, she said phase 3 trials are warranted to confirm the benefits and the safety of a topical therapy that can be used as needed to control intermittent HS flares.

Asked to comment, the lead author of a recently published review article on the “evolving treatment landscape” of HS, James G. Krueger, MD, professor in clinical investigation at Rockefeller University, New York City, agreed that there is an unmet need for effective and safe therapies in milder HS.

“I agree with the premise,” said Dr. Krueger, indicating that phase 3 data will be essential to confirm the promise of this approach. Dr. Krueger, who did not hear the results presented at the EADV meeting, listed several JAK inhibitors in his review that have shown promising efficacy as oral agents and support JAK signaling as a target of HS treatment. 

Topical ruxolitinib (Opzelura) is currently approved in the United States for treating nonsegmental vitiligo in patients aged ≥ 12 years and for mild to moderate atopic dermatitis in patients aged ≥ 12 years. In Europe, it is approved for treatment of nonsegmental vitiligo with facial involvement in patients aged ≥ 12 years. 

Dr. Porter reported no potential conflicts of interest. Dr. Krueger reported financial relationships with more than 25 pharmaceutical companies not including Incyte, which is developing ruxolitinib cream.

By the end of 32 weeks, the score among the crossover patients slightly exceeded that of those on continuous therapy (88.5% vs 81.0%).

AN75 responses at week 32 were 66.7% and 61.5% in the continuous arm and crossover arm, respectively. The proportion of patients reaching an AN90 or AN100 response, meaning clear or almost clear, were 19% and 38.5%, in continuous treatment and crossover arms, respectively.

One of the secondary endpoints was the HS Clinical Response 50, indicating at least a 50% reduction in the AN count with no increase in abscesses or draining fistulae. At 32 weeks, the proportions of patients who met this endpoint were 81.0% and 88.5% in the continuous treatment and crossover arms, respectively. 

The mean reduction in International HS Severity Scoring System scores from baseline were 4.1 and 4.5 in the continuous treatment and crossover arms, respectively. 
 

Patients in the Study Mostly Women, 42% Black Individuals

Most (94%) of the participants were women; about 45% and 42% were White and Black individuals, respectively. Most of the remaining patients were Asian individuals. The median age at entry was 29 years, and the mean body mass index was approximately 34 kg/m². A substantial proportion of patients had systemic comorbidities, according to Dr. Porter, who noted that about 25% had anxiety, depression, or both.

“This phenotype — a high proportion of women with nodules but no draining tunnels and a substantial number of comorbidities — is one we often see in patients with mild HS,” Dr. Porter said.

The safety and tolerability profile of ruxolitinib cream was quite good, according to Dr. Porter, who noted that there were fewer treatment-related adverse events in the open-label extension. Overall, the number of treatment-related adverse events (3.6%), including application site reactions leading to discontinuation (1.8%) was low. 

Although there is a growing list of therapies now approved for HS, Dr. Porter emphasized that all have been developed for moderate to severe disease. She suggested that there is a sizable group of patients with mild disease for whom such therapies as biologics might not be warranted even if symptom relief is needed.

Given this unmet need, she said phase 3 trials are warranted to confirm the benefits and the safety of a topical therapy that can be used as needed to control intermittent HS flares.

Asked to comment, the lead author of a recently published review article on the “evolving treatment landscape” of HS, James G. Krueger, MD, professor in clinical investigation at Rockefeller University, New York City, agreed that there is an unmet need for effective and safe therapies in milder HS.

“I agree with the premise,” said Dr. Krueger, indicating that phase 3 data will be essential to confirm the promise of this approach. Dr. Krueger, who did not hear the results presented at the EADV meeting, listed several JAK inhibitors in his review that have shown promising efficacy as oral agents and support JAK signaling as a target of HS treatment. 

Topical ruxolitinib (Opzelura) is currently approved in the United States for treating nonsegmental vitiligo in patients aged ≥ 12 years and for mild to moderate atopic dermatitis in patients aged ≥ 12 years. In Europe, it is approved for treatment of nonsegmental vitiligo with facial involvement in patients aged ≥ 12 years. 

Dr. Porter reported no potential conflicts of interest. Dr. Krueger reported financial relationships with more than 25 pharmaceutical companies not including Incyte, which is developing ruxolitinib cream.

“Because you know I’m all about that base, ‘bout that base, no acid.” 

Do those words sound familiar? That’s because they’re the lyrics to Meghan Trainor’s “All About That Bass,” slightly tweaked to function as a medical study tool.

Early in med school, J.C. Sue, DO, now a family medicine physician, refashioned the song’s words to help him prepare for a test on acid extruders and loaders. Sue’s version, “All About That Base,” contained his lecture notes. During the exam, he found himself mentally singing his parody and easily recalling the information. Plus, the approach made cramming a lot more palatable.

Sound silly? It’s not. Sue’s approach is backed up by science. A significant body of research has illuminated the positive association between music and memory. And the benefits last. Recently, a 2024 study from Canada suggested that musical memory doesn’t decrease with age. And a 2023 study revealed music was a better cue than food for helping both young and older adults recall autobiographical memories.

Inspired by his success, Sue gave popular songs a medical spin throughout his medical training. “There’s no rule that says studying must be boring, tedious, or torturous,” Sue said. “If you can make it fun, why not?”

Sue isn’t alone. Many physicians say that writing songs, listening to music, or playing instruments improves their focus, energy, and work performance, along with their confidence and well-being.

Why does music work so well?
 

Tune Your Brain to Work With Tunes

Remember learning your ABCs to the tune of “Twinkle, Twinkle, Little Star?” (Or ask any Gen X person about Schoolhouse Rock.)

In the classroom, music is an established tool for teaching kids, said Ruth Gotian, EdD, MS, chief learning officer and associate professor of education in anesthesiology at Weill Cornell Medicine, New York City. But she said musical strategies make studying easier for adults, too, no matter how complex the material.

Christopher Emdin, PhD, Maxine Greene chair and professor of science education at Teachers College, Columbia University, New York City, shares Gotian’s view. When teaching science, engineering, technology, and mathematics (STEM) subjects to high school kids, he challenged them to write raps about the new concepts.

That’s when he saw visible results: As his students took exams, Emdin noticed them nodding and moving their mouths and heads.

“They were literally performing the songs they’d written for themselves,” Emdin said. “When you write a song to a beat, it’s almost like your heartbeat. You know it so well; you can conjure up your memories by reciting the lyrics.”

If songwriting isn’t in your repertoire, you’ll be glad to hear that just listening to music while studying can help with retention. “Music keeps both sides of the brain stimulated, which has been shown to increase focus and motivation,” explained Anita A. Paschall, MD, PhD, Medical School and Healthcare Admissions expert/director of Medical School and Healthcare Admissions at The Princeton Review.
 

‘Mind on a Permanent Vacation’

Paschall’s enthusiasm comes from personal experience. While preparing for her board exams, Jimmy Buffet’s catalog was her study soundtrack. “His songs stayed in my mind. I could hum along without having to think about it, so my brain was free to focus,” she recalled.

Because Paschall grew up listening to Buffet’s tunes, they also evoked relaxing moments from her earlier life, which she found comforting and uplifting. The combination helped make long, intense study sessions more pleasant. After all, when you’re “wasting away again in Margaritaville,” how can you feel stressed and despondent?

Alexander Remy Bonnel, MD, clinical assistant professor of medicine at the University of Pennsylvania and a physician at Pennsylvania Hospital, both in Philadelphia, found ways to incorporate both auditory and visual stimuli in his med school study routine. He listened to music while color-coding his notes to link both cues to the information. As with Paschall, these tactics helped reduce the monotony of learning reams of material.

That gave Bonnel an easy way to establish an important element for memory: Novelty.

“When you need to memorize so many things in a short amount of time, you’re trying to vary ways of internalizing information,” he observed. “You have a higher chance of retaining information if there’s something unique about it.”
 

Building Team Harmony

“Almost every single OR I rotated through in med school had music playing,” Bonnel also recalled. Furthermore, he noticed a pattern to the chosen songs: Regardless of their age, surgeons selected playlists of tunes that had been popular when they were in their 20s. Those golden oldies, from any era, could turn the OR team into a focused, cohesive unit.

Kyle McCormick, MD, a fifth-year resident in orthopedic surgery at New York–Presbyterian Hospital, Columbia University Irving Medical Center, New York City, has also noticed the ubiquity of background music in ORs. Her observation: Surgeons tend to choose universally popular, inoffensive songs, like tracks from Hall & Oates and Fleetwood Mac.

This meshes with the results of a joint survey of nearly 700 surgeons and other healthcare professionals conducted by Spotify and Figure 1 in 2021; 90% of the surgeons and surgical residents who responded said they listened to music in the OR. Rock and pop were the most popular genres, followed by classical, jazz, and then R&B.

Regardless of genre, music helped the surgical teams focus and feel less tense, the surgeons reported. But when training younger doctors, managing complications, or performing during critical points in surgery, many said they’d lower the volume.

Outside the OR, music can also help foster connection between colleagues. For Lawrence C. Loh, MD, MPH, adjunct professor at Dalla Lana School of Public Health at the University of Toronto in Ontario, Canada, playing guitar and piano has helped him connect with his staff. “I’ve played tunes at staff gatherings and recorded videos as encouragement during the emergency response for COVID-19,” he shared.

In his free time, Loh has also organized outings to his local pub’s weekly karaoke show for more than a decade. His goal: “Promote social cohesion and combat loneliness among my friend and social networks.”
 

Get Your Own Musical Boost

If all this sounds like music to your ears, here are some ways to try it yourself.

Find a study soundtrack. When choosing study music, follow Paschall’s lead and pick songs you know well so they’ll remain in the background. Also, compile a soundtrack you find pleasant and mood-boosting to help relieve the tedium of study and decrease stress.

Keep in mind that we all take in and process information differently, said Gotian. So background music during study sessions might not work for you. According to a 2017 study published in Frontiers in Psychology, it can be a distraction and impair learning for some. Do what works.

Get pumped with a “walkup song.” What songs make you feel like you could conquer the world? asked Emdin. Or what soundtrack would be playing if you were ascending a stage to accept an award or walking out to take the mound in the ninth inning? Those songs should be on what he calls your “superhero” or “walkup” playlist. His prescription: Tune in before you begin your workday or start a challenging procedure.

Paschall agrees and recommends her students and clients listen to music before sitting down for an exam. Forget reviewing flashcards for the nth time, she counseled. Putting on headphones (or earbuds) will put you in a “better headspace.”

Choose work and play playlists. As well as incorporating tunes in your clinic or hospital, music can help relieve stress at the end of the workday. “Medical culture can often be detrimental to doctors’ health,” said Sue, who credits music with helping him maintain equanimity.

Bonnel can relate. Practicing and performing with the Penn Medicine Symphony Orchestra offers him a sense of community and relief from the stress of modern life. “For 2 hours every Tuesday, I put my phone away and just play,” he said. “It’s nice to have those moments when I’m temporarily disconnected and can just focus on one thing: Playing.”
 

Scale Up Your Career

Years after med school graduation, Sue still recalls many of the tunes he wrote to help him remember information. When he sings a song in his head, he’ll get a refresher on pediatric developmental milestones, medication side effects, anatomical details, and more, which informs the treatment plans he devises for patients. To help other doctors reap these benefits, Sue created the website Tune Rx, a medical music study resource that includes many of the roughly 100 songs he’s written.

Emdin often discusses his musical strategies during talks on STEM education. Initially, people are skeptical, he said. But the idea quickly rings a bell for audience members. “They come up to me afterward to share anecdotes,” Emdin said. “If you have enough anecdotes, there’s a pattern. So let’s create a process. Let’s be intentional about using music as a learning strategy,” he urged.

Cancer is becoming more common in younger generations. Data show that people under 50 are experiencing higher rates of cancer than any generation before them. As a genetic counselor, I hoped these upward trends in early-onset malignancies would slow with a better understanding of risk factors and prevention strategies. Unfortunately, the opposite is happening. Recent findings from the American Cancer Society reveal that the incidence of at least 17 of 34 cancer types is rising among GenX and Millennials. 

These statistics are alarming. I appreciate how easy it is for patients to get lost in the headlines about cancer, which may shape how they approach their healthcare. Each year, millions of Americans miss critical cancer screenings, with many citing fear of a positive test result as a leading reason. Others believe, despite the statistics, that cancer is not something they need to worry about until they are older. And then, of course, getting screened is not as easy as it should be. 

In my work, I meet with people from both younger and older generations who have either faced cancer themselves or witnessed a loved one experience the disease. One of the most common sentiments I hear from these patients is the desire to catch cancer earlier. My answer is always this: The first and most important step everyone can take is understanding their risk. 

For some, knowing they are at increased risk for cancer means starting screenings earlier — sometimes as early as age 25 — or getting screened with a more sensitive test. 

This proactive approach is the right one. Early detection can dramatically increase survival rates, sometimes by up to eightfold, depending on the type of cancer. It also significantly reduces the burden of total and cancer-specific healthcare costs. While screening may carry some potential risks, clinicians can minimize these risks by adhering to evidence-based guidelines, such as those from the American Cancer Society, and ensuring there is appropriate discussion of treatment options when a diagnosis is made.
 

Normalizing Cancer Risk Assessment and Screening 

A detailed cancer risk assessment and education about signs and symptoms should be part of every preventive care visit, regardless of someone’s age. Further, that cancer risk assessment should lead to clear recommendations and support for taking the next steps. 

This is where care advocacy and patient navigation come in. Care advocacy can improve outcomes at every stage of the cancer journey, from increasing screening rates to improving quality of life for survivors. I’ve seen first-hand how care advocates help patients overcome hurdles like long wait times for appointments they need, making both screening and diagnostic care easier to access. 

Now, with the finalization of a new rule from the Centers for Medicare & Medicaid Services, providers can bill for oncology navigation services that occur under their supervision. This formal recognition of care navigation affirms the value of these services not just clinically but financially as well. It will be through methods like care navigation, targeted outreach, and engaging educational resources — built into and covered by health plans — that patients will feel more in control over their health and have tools to help minimize the effects of cancer on the rest of their lives. 

These services benefit healthcare providers as well. Care navigation supports clinical care teams, from primary care providers to oncologists, by ensuring patients are seen before their cancer progresses to a more advanced stage. And even if patients follow screening recommendations for the rest of their lives and never get a positive result, they’ve still gained something invaluable: peace of mind, knowing they’ve taken an active role in their health. 
 

Fighting Fear With Routine

Treating cancer as a normal part of young people’s healthcare means helping them envision the disease as a condition that can be treated, much like a diagnosis of diabetes or high cholesterol. This mindset shift means quickly following up on a concerning symptom or screening result and reducing the time to start treatment if needed. And with treatment options and success rates for some cancers being better than ever, survivorship support must be built into every treatment plan from the start. Before treatment begins, healthcare providers should make time to talk about sometimes-overlooked key topics, such as reproductive options for people whose fertility may be affected by their cancer treatment, about plans for returning to work during or after treatment, and finding the right mental health support. 

Where we can’t prevent cancer, both primary care providers and oncologists can work together to help patients receive the right diagnosis and treatment as quickly as possible.

Cancer is becoming more common in younger generations. Data show that people under 50 are experiencing higher rates of cancer than any generation before them. As a genetic counselor, I hoped these upward trends in early-onset malignancies would slow with a better understanding of risk factors and prevention strategies. Unfortunately, the opposite is happening. Recent findings from the American Cancer Society reveal that the incidence of at least 17 of 34 cancer types is rising among GenX and Millennials. 

These statistics are alarming. I appreciate how easy it is for patients to get lost in the headlines about cancer, which may shape how they approach their healthcare. Each year, millions of Americans miss critical cancer screenings, with many citing fear of a positive test result as a leading reason. Others believe, despite the statistics, that cancer is not something they need to worry about until they are older. And then, of course, getting screened is not as easy as it should be. 

In my work, I meet with people from both younger and older generations who have either faced cancer themselves or witnessed a loved one experience the disease. One of the most common sentiments I hear from these patients is the desire to catch cancer earlier. My answer is always this: The first and most important step everyone can take is understanding their risk. 

For some, knowing they are at increased risk for cancer means starting screenings earlier — sometimes as early as age 25 — or getting screened with a more sensitive test. 

This proactive approach is the right one. Early detection can dramatically increase survival rates, sometimes by up to eightfold, depending on the type of cancer. It also significantly reduces the burden of total and cancer-specific healthcare costs. While screening may carry some potential risks, clinicians can minimize these risks by adhering to evidence-based guidelines, such as those from the American Cancer Society, and ensuring there is appropriate discussion of treatment options when a diagnosis is made.
 

Normalizing Cancer Risk Assessment and Screening 

A detailed cancer risk assessment and education about signs and symptoms should be part of every preventive care visit, regardless of someone’s age. Further, that cancer risk assessment should lead to clear recommendations and support for taking the next steps. 

This is where care advocacy and patient navigation come in. Care advocacy can improve outcomes at every stage of the cancer journey, from increasing screening rates to improving quality of life for survivors. I’ve seen first-hand how care advocates help patients overcome hurdles like long wait times for appointments they need, making both screening and diagnostic care easier to access. 

Now, with the finalization of a new rule from the Centers for Medicare & Medicaid Services, providers can bill for oncology navigation services that occur under their supervision. This formal recognition of care navigation affirms the value of these services not just clinically but financially as well. It will be through methods like care navigation, targeted outreach, and engaging educational resources — built into and covered by health plans — that patients will feel more in control over their health and have tools to help minimize the effects of cancer on the rest of their lives. 

These services benefit healthcare providers as well. Care navigation supports clinical care teams, from primary care providers to oncologists, by ensuring patients are seen before their cancer progresses to a more advanced stage. And even if patients follow screening recommendations for the rest of their lives and never get a positive result, they’ve still gained something invaluable: peace of mind, knowing they’ve taken an active role in their health. 
 

Fighting Fear With Routine

Treating cancer as a normal part of young people’s healthcare means helping them envision the disease as a condition that can be treated, much like a diagnosis of diabetes or high cholesterol. This mindset shift means quickly following up on a concerning symptom or screening result and reducing the time to start treatment if needed. And with treatment options and success rates for some cancers being better than ever, survivorship support must be built into every treatment plan from the start. Before treatment begins, healthcare providers should make time to talk about sometimes-overlooked key topics, such as reproductive options for people whose fertility may be affected by their cancer treatment, about plans for returning to work during or after treatment, and finding the right mental health support. 

Where we can’t prevent cancer, both primary care providers and oncologists can work together to help patients receive the right diagnosis and treatment as quickly as possible.

Primary care physicians (PCPs) play a key role in treating young patients as they progress through the “atopic march” from atopic dermatitis through food allergy, asthma, and allergic rhinitis. They can also help prevent the process from starting.

“The PCP is usually the first clinician a family with concerns about atopic conditions sees, unless they first visit urgent care or an emergency department after an allergic reaction to food. Either way, families rely on their PCP for ongoing guidance,” said Terri F. Brown-Whitehorn, MD, attending physician in the Division of Allergy and Immunology at the Center for Pediatric Eosinophilic Disorders and the Integrative Health Program at Children’s Hospital of Philadelphia.

“The most important thing PCPs can do is know that the atopic march exists, how it progresses over time, and what signs and symptoms to look for,” she told this news organization.
 

The Atopic March

The atopic march describes the progression of allergic diseases in a child over time, with atopic dermatitis and food allergy in infancy tending to be followed by allergic rhinitis and asthma into later childhood and adulthood.

Although the pathophysiology of the inflammation that precedes atopic dermatitis is unclear, two main hypotheses have been proposed. The first suggests a primary immune dysfunction leads to immunoglobulin E (IgE) sensitization, allergic inflammation, and a secondary disturbance of the epithelial barrier; the second starts with a primary defect in the epithelial barrier that leads to secondary immunologic dysregulation and results in inflammation.

Genetics, infection, hygiene, extreme climate, food allergens, probiotics, aeroallergens, and tobacco smoke are thought to play roles in atopic dermatitis. An estimated 10%-12% of children and 1% of adults in the United States have been reported to have the condition, and the prevalence appears to be increasing. An estimated 85% of cases occur during the first year of life and 95% before the age of 5 years.

“Atopy often, though not always, runs in families, so PCPs should inquire about the history of atopic dermatitis, IgE-mediated food allergies, allergic rhinitis, and asthma in the patient’s siblings, parents, and grandparents,” Brown-Whitehorn said.
 

Key Educators

PCPs treat the full gamut of atopic conditions and are key educators on ways families can help mitigate their children’s atopic march or stop it before it begins, said Gerald Bell Lee, MD, an allergist and immunologist at Children’s Healthcare of Atlanta and an associate professor in the Division of Allergy and Immunology at Emory University School of Medicine, Atlanta.

“Most parents who bring their infants with eczema to the PCP assume their child ate something that caused their rash. But the relationship between atopic dermatitis, a type of eczema, and food allergy is more complicated,” he added.

Lee said PCPs should explain to their patients what atopic dermatitis is, how it starts and progresses, and how families can help prevent the condition by, for example, introducing allergenic foods to infants at around 4-6 months of age.
 

Atopic Dermatitis

PCPs should inform parents and other caregivers to wash their hands before moisturizing their child, take care not to contaminate the moisturizer, and bathe their child only when the child is dirty.

“Soap removes protective natural skin oils and increases moisture loss, and exposure to soap and bathing is a main contributor to eczema,” said Lee. “Dry skin loses its protective barrier, allowing outside agents to penetrate and be identified by the immune system.”

“According to one hypothesis, parents may eat food, not wash their hands afterwards, then moisturize their baby. This unhygienic practice spreads food proteins from the adult’s meal, and possibly from contaminants present in the moisturizer, all over the baby’s body,” he added.

Lee said he and his colleagues discourage overbathing babies to minimize the risk for skin injury that begins the atopic march: “New parents are inundated with infant skincare messaging and products. But we need to weigh societal pressures against practicality and ask, ‘Is the child’s skin actually dirty?’ ”

Atopic dermatitis tends to appear on the extensor surfaces, face, and scalp in infants and around arm and leg creases in toddlers and older children. Severe forms of the condition can be more widely distributed on the body, said Aarti P. Pandya, MD, medical director of the Food Allergy Center at Children’s Mercy Kansas City and clinical assistant professor of pediatrics at the University of Missouri-Kansas City School of Medicine, Kansas City, Missouri.
 

Avoid Triggers, Minimize Flares

Triggers of eczema are varied and common. To help minimize flares, PCPs can encourage caregivers to avoid products with fragrances or dyes, minimize the use of soaps, and completely rinse laundry detergent from clothing and household items. “Advise them to keep fingernails short and control dander, pollen, mold, household chemicals, and tobacco smoke, as well as the child’s stress and anxiety, which can also be a trigger,” Lee said.

“Skin infections from organisms such as staph, herpes, or coxsackie can also exacerbate symptoms,” Brown-Whitehorn added. “PCPs can educate caregivers to avoid all known triggers and give them an ‘action plan’ to carry out when skin flares.”
 

Food Allergies

Parents may be unaware food allergens can travel far beyond the plate, Lee said. Researchers vacuuming household bedding, carpets, furniture, and other surfaces have detected unnoticeably tiny quantities of allergenic food proteins in ordinary house dust. Touching this dust appears to provide the main exposure to those allergens.

“According to the dual exposure to allergen hypothesis, an infant’s tolerance to antigens occurs through high-dose exposure by mouth, and allergic sensitization occurs through low-dose exposure through the skin,” he said. “As young as four to six months of age, even before eating solid food, a child develops eczema, has a leaky skin barrier, comes in contact with food, and develops a food allergy.”

IgE-mediated food allergies can begin at any age. “Symptoms occur when a food is ingested and the patient develops symptoms including but not limited to urticaria, angioedema, pruritus, flushing, vomiting, diarrhea, coughing, wheezing, difficulty breathing, presyncope, or syncope,” Pandya noted.

In the case of eosinophilic esophagitis, which may also be part of the atopic march, infants and toddlers often have challenging-to-treat symptoms of reflux, while school-age children have reflux and abdominal pain, and adolescents and adults may experience difficulty swallowing and impactions of food or pills, Brown-Whitehorn said.

To differentiate between food allergy and contact dermatitis, Lee suggested providers ask, “ ’Is the rash hives? If yes, is the rash generalized or in a limited area?’ Then consider the statistical probabilities. Skin problems after milk, egg, wheat, soy, peanut, tree nut, fish, shellfish, or sesame are likely due to IgE-mediated food allergy, but after ketchup or strawberry are probably from skin contact.”
 

Allergic Rhinitis and Asthma

“For asthma, ask about frequency of night cough and symptoms with exercise, laughing, or crying. For allergic rhinitis, look for runny nose, itchy eyes, or sneezing,” Brown-Whitehorn said.

Testing and Monitoring

Assessing the extent of eczema with the Eczema Area and Severity Index or the SCORing Atopic Dermatitis index takes time but may be necessary to obtain insurance coverage for treatments such as biologics.

Avoid ordering IgE food panels, which can result in false positives that can lead to loss of tolerance and nutritional deficiencies; psychological harm from bullying, anxiety, and decreased quality of life; and higher food and healthcare costs, Pandya said.

Treatments
Caregivers may be wary about treatments, and all the three experts this news organization spoke with stressed the importance of educating caregivers about how treatments work and what to expect from them.

“Early and aggressive atopic dermatitis treatment could prevent sensitization to food or aeroallergens, which could help prevent additional atopic diseases, including those on the atopic march,” Pandya said. “Topical steroids are considered first line at any age. Topical phosphodiesterase inhibitors are approved at 3 months of age and above. Topical calcineurin inhibitors are approved at 2 years of age and above. Wet wrap therapy and bleach baths can be effective. Other options include biologic therapy, allergen immunotherapy, and UV therapy.”

“Epinephrine auto-injectors can counteract food reactions. For allergic rhinitis, non-sedating antihistamines, steroidal nasal sprays, and nasal antihistamines help. Asthma treatments include various inhaled medications,” Brown-Whitehorn added.
 

When to Refer to Specialists

Involving an allergist, dermatologist, pulmonologist, or ear nose throat specialist to the patient’s care team is advisable in more challenging cases.

If a child is younger than 3 months and has moderate to severe atopic dermatitis, an underlying immune defect may be to blame, so an allergy and immunology assessment is warranted, Brown-Whitehorn said. “An allergist can help any child who has recurrent coughing or wheezing avoid the emergency room or hospitalization.”

“In pediatrics, we always try to find the medication, regimen, and avoidance strategies that use the least treatment to provide the best care for each patient,” Brown-Whitehorn added. “Children eat, play, learn, and sleep, and every stage of the atopic march affects each of these activities. As clinicians, we need to be sure that we are helping children make the best of all these activities.”

Brown-Whitehorn reported financial relationships with DBV Technologies and Regeneron Pharmaceuticals. Lee reported financial relationships with Novartis. Pandya reported financial relationships with DBV Technologies, Thermo Fisher Scientific, and Sanofi.

In the case of eosinophilic esophagitis, which may also be part of the atopic march, infants and toddlers often have challenging-to-treat symptoms of reflux, while school-age children have reflux and abdominal pain, and adolescents and adults may experience difficulty swallowing and impactions of food or pills, Brown-Whitehorn said.

To differentiate between food allergy and contact dermatitis, Lee suggested providers ask, “ ’Is the rash hives? If yes, is the rash generalized or in a limited area?’ Then consider the statistical probabilities. Skin problems after milk, egg, wheat, soy, peanut, tree nut, fish, shellfish, or sesame are likely due to IgE-mediated food allergy, but after ketchup or strawberry are probably from skin contact.”
 

Allergic Rhinitis and Asthma

“For asthma, ask about frequency of night cough and symptoms with exercise, laughing, or crying. For allergic rhinitis, look for runny nose, itchy eyes, or sneezing,” Brown-Whitehorn said.

Testing and Monitoring

Assessing the extent of eczema with the Eczema Area and Severity Index or the SCORing Atopic Dermatitis index takes time but may be necessary to obtain insurance coverage for treatments such as biologics.

Avoid ordering IgE food panels, which can result in false positives that can lead to loss of tolerance and nutritional deficiencies; psychological harm from bullying, anxiety, and decreased quality of life; and higher food and healthcare costs, Pandya said.

Treatments
Caregivers may be wary about treatments, and all the three experts this news organization spoke with stressed the importance of educating caregivers about how treatments work and what to expect from them.

“Early and aggressive atopic dermatitis treatment could prevent sensitization to food or aeroallergens, which could help prevent additional atopic diseases, including those on the atopic march,” Pandya said. “Topical steroids are considered first line at any age. Topical phosphodiesterase inhibitors are approved at 3 months of age and above. Topical calcineurin inhibitors are approved at 2 years of age and above. Wet wrap therapy and bleach baths can be effective. Other options include biologic therapy, allergen immunotherapy, and UV therapy.”

“Epinephrine auto-injectors can counteract food reactions. For allergic rhinitis, non-sedating antihistamines, steroidal nasal sprays, and nasal antihistamines help. Asthma treatments include various inhaled medications,” Brown-Whitehorn added.
 

When to Refer to Specialists

Involving an allergist, dermatologist, pulmonologist, or ear nose throat specialist to the patient’s care team is advisable in more challenging cases.

If a child is younger than 3 months and has moderate to severe atopic dermatitis, an underlying immune defect may be to blame, so an allergy and immunology assessment is warranted, Brown-Whitehorn said. “An allergist can help any child who has recurrent coughing or wheezing avoid the emergency room or hospitalization.”

“In pediatrics, we always try to find the medication, regimen, and avoidance strategies that use the least treatment to provide the best care for each patient,” Brown-Whitehorn added. “Children eat, play, learn, and sleep, and every stage of the atopic march affects each of these activities. As clinicians, we need to be sure that we are helping children make the best of all these activities.”

Brown-Whitehorn reported financial relationships with DBV Technologies and Regeneron Pharmaceuticals. Lee reported financial relationships with Novartis. Pandya reported financial relationships with DBV Technologies, Thermo Fisher Scientific, and Sanofi.

Depending on one’s perspective, “mast cell activation syndrome (MCAS)” is either a relatively rare, narrowly defined severe allergic condition or a vastly underrecognized underlying cause of multiple chronic inflammatory conditions that affect roughly 17% of the entire population. 

Inappropriate activation of mast cells — now termed mast cell activation disease (MCAD) — has long been known to underlie allergic symptoms and inflammation, and far less commonly, neoplasias such as mastocytosis. The concept of chronic, persistent MCAS associated with aberrant growth and dystrophism is more recent, emerging only in the last couple of decades as a separate entity under the MCAD heading. 

Observational studies and clinical experience have linked signs and symptoms of MCAS with other inflammatory chronic conditions such as hypermobile Ehlers-Danlos Syndrome (EDS), postural orthostatic tachycardia syndrome (POTS), myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS), and recently, long COVID. However, those conditions themselves are diagnostically challenging, and as yet there is no proof of causation.

The idea that MCAS is the entity — or at least, a key one — at the center of “a confoundingly, extraordinarily heterogeneous chronic multisystem polymorbidity” was the theme of a recent 4-day meeting of a professional group informally dubbed “Masterminds.” Since their first meeting in 2018, the group has grown from about 35 to nearly 650 multidisciplinary professionals. 

Stephanie L. Grach, MD, assistant professor of medicine at the Mayo Clinic, Rochester, Minnesota, gave an introductory talk about the importance of changing “the medical paradigm around complex chronic illness.” Much of the rest of the meeting was devoted to sharing approaches for managing MCAS comorbidities, including dysautonomia, hypermobility, and associated craniocervical dysfunction, and various other multi-system conditions characterized by chronic pain and/or fatigue. Several talks covered the use of agents that block mast cell activity as potential treatment. 

In an interview, Grach said “the meeting was an exciting example of how not only research, but also medicine, is moving forward, and it’s really cool to see that people are independently coming to very similar conclusions about shared pathologies, and because of that, the importance of overlap amongst complex medical conditions that historically have really been poorly addressed.”

She added, “mast cell activation, or mast cell hyperactivity, is one part of the greater picture. What’s important about the mast cell component is that of the multiple different targetable pathologies, it’s one that currently has potential available therapies that can be explored, some of them relatively easily.”

But Christopher Chang, MD, PhD, chief of the Pediatric Allergy and Immunology program, Joe DiMaggio Children’s Hospital, Hollywood, Florida, sees it differently. In an interview, he noted that the reason for disagreement over what constitutes MCAS is that “it doesn’t have a lot of objective findings that we can identify. ... We know that mast cells are important immune cells, just like all immune cells are important. It seems like whenever someone has unexplained symptoms, people try to blame it on mast cells. But it’s very hard to prove that.” 
 

Two Definitions Characterize the Illness Differently

One proposed “consensus” MCAS definition was first published in 2011 by a group led by hematologist Peter Valent, MD, of the Medical University of Vienna in Austria. It has been revised since, and similar versions adopted by medical societies, including the American Academy of Allergy, Asthma & Immunology (AAAAI). The most recent versions propose three core MCAS criteria: 

• Typical clinical signs of severe, recurrent (episodic) systemic (at least two organ systems) MCA are present (often in the form of anaphylaxis).
• The involvement of mast cells (MCs) is documented by biochemical studies, preferably an increase in serum tryptase levels from the individual’s baseline to plus 20% + 2 ng/mL.
• Response of symptoms to therapy with MC-stabilizing agents, drugs directed against MC mediator production, or drugs blocking mediator release or effects of MC-derived mediators.

The following year, a separate publication authored by Gerhard J. Molderings, MD, University of Bonn in Germany, and colleagues proposed a much broader MCAS definition. Also revised since, the latest “consensus-2” was published in 2020. This definition consists of one major criterion: “A constellation of clinical complaints attributable to pathologically increased MC activity, ie, MC mediator release syndrome.” This “constellation” involves conditions of nearly every organ system that, taken together, are estimated to affect up to 17% of the entire population. These are just a few examples: 

• Constitutional: Chronic fatigue, flushing, or sweats
• Dermatologic: Rashes or lesions
• Ophthalmologic: dry eyes
• Oral: Burning or itching in mouth
• Pulmonary: Airway inflammation at any/all levels
• Cardiovascular: Blood pressure lability or codiagnosis of POTS is common
• Gastrointestinal: Reflux, dysphagia, or malabsorption
• Genitourinary: Endometriosis, dysmenorrhea, or dyspareunia
• Musculoskeletal/connective tissue: Fibromyalgia or diagnosis of hypermobile EDS is common
• Neurologic: Headaches or sensory neuropathies
• Psychiatric: Depression or anxiety
• Endocrinologic: Thyroid disease or dyslipidemia
• Hematologic: Polycythemia or anemia (after ruling out other causes)

The diagnosis is made by fulfilling that major criterion, plus at least one objective assessment of pathologically increased release of MC mediators, including infiltrates, abnormal MC morphology, or MC genetic changes shown to increase MC activity. Other alternatives include evidence of above-normal levels of MC mediators, including tryptase, histamine or its metabolites, heparin, or chromatin A, in whole blood, serum, plasma, or urine. Symptomatic response to MC activation inhibitors can also be used but isn’t required as it is in the other definition. 
 

Underdiagnosis vs Overdiagnosis

Lawrence B. Afrin, MD, senior consultant in hematology/oncology at the AIM Center for Personalized Medicine, Westchester, New York, and lead author of the 2020 update of the broader “consensus-2” criteria, said in an interview, “we now know MCAS exists, and it’s prevalent, even though, for understandable and forgivable reasons, we’ve been missing it all along. ... If you see a patient who has this chronic, multisystem unwellness with general themes of inflammation plus or minus allergic issues and you can’t find some other rational explanation that better accounts for what’s going on ... then it’s reasonable to think to include MCAS in the differential diagnosis. If the patient happens not to fit the diagnostic criteria being advanced by one group, that doesn’t necessarily rule out the possibility that this is still going on.”

Afrin, along with his coauthors, faulted the narrower “consensus-1” definition for lacking data to support the “20% + 2” criteria for requiring the difficult determination of a patient’s “baseline” and for requiring evidence of response to treatment prior to making the diagnosis. Not all patients will respond to a given histamine blocker, he noted. 

But Lawrence B. Schwartz, MD, PhD, an author on both the Valent and AAAAI criteria, disagreed, noting that the narrower criteria “appear to have a high degree of specificity and sensitivity when the reaction is systemic and involves hypotension. Less severe clinical events, particularly involving the gastrointestinal or central nervous systems, do not have precise clinical or biomarker criteria for identifying mast cell involvement.” 

Added Schwartz, who is professor of medicine and chair of the Division of Rheumatology, Allergy, and Immunology and program director of Allergy and Immunology, Virginia Commonwealth University (VCU), Richmond, “when mast cell activation events occur only in the skin, we refer to it as chronic urticaria and in the airways or conjunctiva of allergic individuals as allergic asthma, rhinitis, and/or conjunctivitis. The absence of specific criteria for mast cell activation in the GI [gastrointestinal] tract or CNS [central nervous system] neither rules in mast cell involvement nor does it rule out mast cell involvement. Thus, more research is needed to find better diagnostic criteria.”

Schwartz also pointed to a recent paper reporting the use of artificial intelligence models to “quantify diagnostic precision and specificity” of “alternative” MCAS definitions. The conclusion was a “lack of specificity is pronounced in relation to multiple control criteria, raising the concern that alternative criteria could disproportionately contribute to MCAS overdiagnosis, to the exclusion of more appropriate diagnoses.”

During the meeting, Afrin acknowledged that the broader view risks overdiagnosis of MCAS. However, he also referenced Occam’s razor, the principle that the simplest explanation is probably the best one. “Which scenario is more likely? Multiple diagnoses and problems that are all independent of each other vs one diagnosis that’s biologically capable of causing most or all of the findings, ie, the simplest solution even if it’s not the most immediately obvious solution?”

He said in an interview: “Do we have any proof that MCAS is what’s underlying hypermobile Ehlers-Danlos or POTS or chronic fatigue? No, we don’t have any proof, not because anybody has done studies that have shown there to be no connection but simply because we’re so early in our awareness that the disease even exists that the necessary studies haven’t even been done yet.”

At the meeting, Afrin introduced proposals to turn the “Masterminds” group into a formal professional society and to launch a journal. He also gave an update on progress in developing a symptom assessment tool both for clinical use and to enable clinical trials of new drugs to target mast cells or their mediators. The plan is to field test the tool in 2025 and publish those results in 2026. 

Grach, Afrin, and Chang had no disclosures. Schwartz discovered tryptase and invented the Thermo Fisher tryptase assay, for which his institution (VCU) receives royalties that are shared with him. He also invented monoclonal antibodies used for detecting mast cells or basophils, for which VCU receives royalties from several companies, including Millipore, Santa Cruz, BioLegend, and Hycult Biotech, that are also shared with him. He is a paid consultant for Blueprint Medicines, Celldex Therapeutics, Invea, Third Harmonic Bio, HYCOR Biomedical, Jasper, TerSera Therapeutics, and GLG. He also serves on an AstraZeneca data safety monitoring board for a clinical trial involving benralizumab treatment of hypereosinophilic syndrome and receives royalties from UpToDate (biomarkers for anaphylaxis) and Goldman-Cecil Medicine (anaphylaxis).

TOPLINE:

A study has found that less than half of US veterans on chronic immunosuppressive medications, and a much lower percentage of those younger than 50 years, received at least one dose of the recombinant zoster vaccine (RZV) by mid-2023; the low rate of herpes zoster vaccination in this immunocompromised group, especially among younger individuals, is concerning.

METHODOLOGY:

• In 2021, the Food and Drug Administration authorized the use of RZV for adults aged 18 years or older on chronic immunosuppressive medications because of their high risk for herpes zoster and its related complications, followed by updated guidance from the Centers for Disease Control and Prevention and American College of Rheumatology in 2021 and 2022, respectively.
• This study aimed to assess the receipt of RZV among veterans receiving immunosuppressive medications within the Veterans Health Administration (VHA) healthcare system before and after the expanded indications in February 2022.
• It included 190,162 veterans who were prescribed one or more immunosuppressive medications for at least 90 days at 130 medical facilities between January 1, 2018, and June 30, 2023.
• A total of 23,295 veterans (12.3%) were younger than 50 years by the end of the study period.
• The outcome measured was the percentage of veterans with one or more doses of RZV documented during the study period.

TAKEAWAY:

• Among veterans aged 50 years or older, 36.2% and 49.8% received an RZV before the expanded indication and by mid-2023, respectively. Even though the rate of vaccination is higher than that observed in the 2021 National Health Interview Survey, significant room for improvement remains.
• Among veterans younger than 50 years, very few (2.8%) received an RZV before the expanded indication, and only 13.4% received it by mid-2023.
• Demographic factors associated with lower odds of vaccination included male sex, African American or unknown race, and nonurban residence (P ≤ .004 for all).
• Those who received targeted synthetic disease-modifying antirheumatic drugs (DMARDs) alone or in combination with other drugs or those who received other vaccines were more likely to receive RZV than those who received conventional synthetic DMARD monotherapy (P < .001 for both).

IN PRACTICE:

“Future work to improve RZV vaccination in patients at high risk should focus on creating informatics tools to identify individuals at high risk and standardizing vaccination guidelines across subspecialties,” the authors wrote.

This study was led by Sharon Abada, MD, University of California, San Francisco. It was published online on October 11, 2024, in JAMA Network Open.

LIMITATIONS:

This study may not be generalizable to nonveteran populations or countries outside the United States. Limitations also included difficulty with capturing vaccinations not administered within the VHA system, which may have resulted in an underestimation of the percentage of patients vaccinated.

Among 111 prescription or over-the-counter products for acne that contain benzoyl peroxide (BPO), 38 (34%) contained benzene levels above the Food and Drug Administration (FDA) limit of 2 ppm, according to results from an analysis that used gas chromatography–mass spectrometry and other methods.

The analysis, which was published in the Journal of Investigative Dermatology and expands on a similar study released more than 6 months ago, also found that encapsulated BPO products break down into benzene at room temperature but that refrigerating them may mitigate this effect.

“Our research provides the first experimental evidence that cold storage can help reduce the rate of benzoyl peroxide breakdown into benzene,” said one of the study authors, Christopher G. Bunick, MD, PhD, associate professor of dermatology at Yale University, New Haven, Connecticut. “Therefore, cold storage throughout the entire supply chain — from manufacturing to patient use — is a reasonable and proportional measure at this time for those continuing to use benzoyl peroxide medicine.” One acne product, the newer prescription triple-combination therapy (adapalene-clindamycin-BPO) “already has a cold shipping process in place; the patient just needs to continue that at home,” he noted.

For the study — which was funded by an independent lab, Valisure — researchers led by Valisure CEO and founder David Light, used gas chromatography-mass spectrometry to detect benzene levels in 111 BPO drug products from major US retailers and selected ion flow tube mass-spectrometry to quantify the release of benzene in real time. Benzene levels ranged from 0.16 ppm to 35.30 ppm, and 38 of the products (34%) had levels above the FDA limit of 2 ppm for drug products. “The results of the products sampled in this study suggest that formulation is likely the strongest contributor to benzene concentrations in BPO drug products that are commercially available, since the magnitude of benzene detected correlates most closely with specific brands or product types within certain brands,” the study authors wrote.

When the researchers tested the stability of a prescription encapsulated BPO drug product at cold (2 °C) and elevated temperature (50 °C), no apparent benzene formation was observed at 2 °C, whereas high levels of benzene formed at 50 °C, “suggesting that encapsulation technology may not stabilize BPO drug products, but cold storage may greatly reduce benzene formation,” they wrote.

In another component of the study, researchers exposed a BP drug product to a UVA/UVB lamp for 2 hours and found detectable benzene through evaporation and substantial benzene formation when exposed to UV light at levels below peak sunlight. The experiment “strongly justifies the package label warnings to avoid sun exposure when using BPO drug products,” the authors wrote. “Further evaluation to determine the influence of sun exposure on BPO drug product degradation and benzene formation is warranted.”

In an interview, John Barbieri, MD, MBA, assistant professor of dermatology at Harvard Medical School and director of the Advanced Acne Therapeutics Clinic at Brigham and Women’s Hospital, Boston, Massachusetts characterized the findings as “an important issue that we should take seriously.” However, “we also must not overreact.” 

BPO is a foundational acne treatment without any clear alternative, he said, pointing out that no evidence currently exists “to support that routine use of benzoyl peroxide–containing products for acne is associated with a meaningful risk of benzene in the blood or an increased risk of cancer.”

And although it is prudent to minimize benzene exposure as much as possible, Barbieri continued, “it is not clear that these levels are a clinically meaningful incremental risk in the setting of an acne cream or wash. There is minimal cutaneous absorption of benzene, and it is uncertain how much benzene aerosolizes with routine use, particularly for washes which are not left on the skin.”

Bunick said that the combined data from this and the study published in March 2024 affected which BPO products he recommends for patients with acne. “I am using exclusively the triple combination therapy (adapalene-clindamycin-benzoyl peroxide) because I know it has the necessary cold supply chain in place to protect the product’s stability. I further encourage patients to place all their benzoyl peroxide–containing products in the refrigerator at home to reduce benzene formation and exposure.”

Bunick reported having served as an investigator and/or a consultant/speaker for many pharmaceutical companies, including as a consultant for Ortho-Dermatologics; but none related to this study. Barbieri reported having no relevant disclosures.
