Atopic Dermatitis

Key clinical point: Baricitinib treatment was effective and well-tolerated in patients with moderate to severe atopic dermatitis (AD) who were followed-up for 3 months in real-world settings.

Major finding: Baricitinib led to a significant reduction in the Eczema Area Severity Index (21.5 ± 13.2 vs 9.3 ± 9.0) and objective Scoring AD (45.9 ± 12.3 vs 28.2 ± 15.5) scores at 3 months vs start visit (both P < .001). The treatment discontinuation rate was 16.7%, with two patients discontinuing baricitinib due to adverse events.

Study details: This was an interim analysis of the TREATgermany registry that included 81 adult patients with moderate to severe AD who received baricitinib and concomitant topical treatment, of whom 49 had initiated baricitinib at a registry visit; 26 of these did not switch from a previous systemic drug and had their first follow-up visit at 3 months.

Key clinical point: Passive smoking during pregnancy is associated with an increased risk for atopic dermatitis (AD) in offspring; however, the association between active smoking during pregnancy and AD in offspring remains unestablished.

Major finding: Passive smoking during pregnancy led to a higher risk for AD in offspring (odds ratio [OR] 1.52; 95% CI 1.36-1.70); however, active smoking during pregnancy did not increase the risk for AD in offspring (OR 0.96; 95% CI 0.86-1.07).

Study details: This meta-analysis of 15 observational studies included children or mother-child pairs who underwent either questionnaire-based or physician assessment for AD diagnosis and questionnaire-based assessment or cotinine level measurement for evaluating exposure to active or passive smoking.

Key clinical point: Tralokinumab-mediated inhibition of interleukin (IL)-13 improved epidermal pathology and reduced the expression of key atopic dermatitis (AD) biomarkers in the serum of patients with moderate to severe AD.

Major finding: At week 16, tralokinumab vs placebo led to a significantly greater decrease from baseline in serum levels of type 2 biomarkers (CCL17/TARC, periostin, immunoglobulin E, and IL-22; all P < .05), a greater mean percentage change in the Eczema Area Severity Index score (−55.6 vs −36.7), and improved expression of genes dysregulated in AD (46.6% vs 16.4%; P < .001).

Study details: This study involved the collection of blood samples from 802 patients with moderate to severe AD randomized in the ECZTRA 1 and ECZTEND trials, followed by the selection of a subset of 299 patients with relevant samples available who had received tralokinumab (n = 223) or placebo (n = 76).

FROM AAD 2024

SAN DIEGO — Moderate to severe atopic dermatitis reduces linear growth in children younger than 12 years, results from an ongoing 10-year observational study showed.

“We need to sort out whether this is reversed by newer treatments, especially in the 6- to 11-year-olds, as well as the factors that underlie it in atopic dermatitis,” said the study’s first author Amy S. Paller, MD, chair of dermatology, Northwestern University, Chicago, Illinois, following the annual meeting of the American Academy of Dermatology, where the study was presented during a poster session.
 

Atopic Dermatitis Impacts Growth

In the ongoing international study called PEDISTAD, researchers enrolled 1326 children younger than 12 years with moderate to severe atopic dermatitis inadequately controlled by topical therapies who were candidates to receive systemic medications. They assessed the percentage of patients above the 50th percentile and the mean percentiles for height, weight, and body mass index (BMI) at baseline against the Centers for Disease Control and Prevention’s (CDC’s) Learning Management System reference healthy population, by age in months, and compared results to the CDC’s standardized growth curves for healthy children aged 0-12 years.

The investigators found that at baseline, compared with the age-specific population norms, 50% of men and 51% of women in the PEDISTAD study were above the 50th percentile for weight, but only 38% and 52%, respectively, were above the 50th percentile for height. Among patients aged 5-12 years, only 28% of men and 47% of women were above the 50th percentile for height, while 69% of men and 71% of women were above the 50th percentile for BMI.

Dr. Paller said that she was “not really surprised by the reduction in linear growth, since there are so many factors that may contribute,” including chronic inflammation, poor sleep, and the use of topical and systemic steroids. “But [it’s] good to have this data as an opportunity to see if our improved therapies can reverse this.”

She said that she was “a bit surprised by the increase in weight and body mass index, but this could reflect less physical activity/sports [participation and] deserves more investigation,” and added that the findings “mesh nicely with new attention on bone growth with good control of atopic dermatitis in this age group.”

Dr. Paller acknowledged certain limitations of the study, including the fact that those enrolled are a heterogeneous cohort with variable treatment regimens.
 

Some Answers, More Questions

Adam Friedman, MD, professor and chair of dermatology at George Washington University, Washington, DC, who was asked to comment on the findings, said that atopic dermatitis “should be considered the cutaneous manifestations of a systemic inflammatory disease, though even if it were not, the impact on daily and nightly activities [such as sleep] could indirectly have systemic medical consequences.”

The data presented “highlights that children with moderate to severe disease have higher BMIs and shorter height than matched counterparts, likely owing to the treasure trove of direct and indirect consequences of uncontrolled type 2 inflammation,” he said. “What I would like to know, and as the authors astutely noted, could treatment, and especially early intervention, prevent or even alter this impact?”

Dr. Paller disclosed that she is a consultant for several pharmaceutical companies, including Sanofi and Regeneron, the study sponsor. She is also an investigator for AbbVie, Dermavant, Eli Lilly, Incyte, Janssen, Krystal, LEO Pharma, and UCB and is a member of the data monitoring safety board for AbbVie, Abeona, Catawba, Galderma, and InMed. Dr. Friedman, who was not involved with the study, had no relevant disclosures.

FROM AAD 2024

SAN DIEGO — Moderate to severe atopic dermatitis reduces linear growth in children younger than 12 years, results from an ongoing 10-year observational study showed.

“We need to sort out whether this is reversed by newer treatments, especially in the 6- to 11-year-olds, as well as the factors that underlie it in atopic dermatitis,” said the study’s first author Amy S. Paller, MD, chair of dermatology, Northwestern University, Chicago, Illinois, following the annual meeting of the American Academy of Dermatology, where the study was presented during a poster session.
 

Atopic Dermatitis Impacts Growth

In the ongoing international study called PEDISTAD, researchers enrolled 1326 children younger than 12 years with moderate to severe atopic dermatitis inadequately controlled by topical therapies who were candidates to receive systemic medications. They assessed the percentage of patients above the 50th percentile and the mean percentiles for height, weight, and body mass index (BMI) at baseline against the Centers for Disease Control and Prevention’s (CDC’s) Learning Management System reference healthy population, by age in months, and compared results to the CDC’s standardized growth curves for healthy children aged 0-12 years.

The investigators found that at baseline, compared with the age-specific population norms, 50% of men and 51% of women in the PEDISTAD study were above the 50th percentile for weight, but only 38% and 52%, respectively, were above the 50th percentile for height. Among patients aged 5-12 years, only 28% of men and 47% of women were above the 50th percentile for height, while 69% of men and 71% of women were above the 50th percentile for BMI.

Dr. Paller said that she was “not really surprised by the reduction in linear growth, since there are so many factors that may contribute,” including chronic inflammation, poor sleep, and the use of topical and systemic steroids. “But [it’s] good to have this data as an opportunity to see if our improved therapies can reverse this.”

She said that she was “a bit surprised by the increase in weight and body mass index, but this could reflect less physical activity/sports [participation and] deserves more investigation,” and added that the findings “mesh nicely with new attention on bone growth with good control of atopic dermatitis in this age group.”

Dr. Paller acknowledged certain limitations of the study, including the fact that those enrolled are a heterogeneous cohort with variable treatment regimens.
 

Some Answers, More Questions

Adam Friedman, MD, professor and chair of dermatology at George Washington University, Washington, DC, who was asked to comment on the findings, said that atopic dermatitis “should be considered the cutaneous manifestations of a systemic inflammatory disease, though even if it were not, the impact on daily and nightly activities [such as sleep] could indirectly have systemic medical consequences.”

The data presented “highlights that children with moderate to severe disease have higher BMIs and shorter height than matched counterparts, likely owing to the treasure trove of direct and indirect consequences of uncontrolled type 2 inflammation,” he said. “What I would like to know, and as the authors astutely noted, could treatment, and especially early intervention, prevent or even alter this impact?”

SAN DIEGO — Whether you completed your dermatology residency training 20 years ago or 2 years ago, recent advances in treatments for atopic dermatitis (AD) have likely influenced your “go to” interventions when treating children with AD, according to Lawrence F. Eichenfield, MD.

“There have been many changes in the understanding of AD and recognition of the variable courses of the disease, and the associated allergic and nonallergic comorbidities,” Dr. Eichenfield, chief of pediatric and adolescent dermatology at Rady Children’s Hospital-San Diego in California, said at the Society for Pediatric Dermatology meeting, held the day before the annual meeting of the American Academy of Dermatology. “With our revolutionary systemic and evolving topical therapies, we are in a new day of pediatric management.”

Drawing from 2023 American Academy of Dermatology guidelines of care on topical treatments of AD and his own clinical experience, he shared his perspective on “what’s tried and true” in care for patients with persistent eczema:

Both bathing and moisturizing leave skin moist. It’s well established that the use of moisturizers/emollients minimizes xerosis and the amount of prescription anti-inflammatory medications, but limited evidence exists to recommend a particular ingredient and formulation, said Dr. Eichenfield, also professor of dermatology and pediatrics at the University of California, San Diego. “Future studies may tell us whether specific moisturizers work better than others, and/or if early interventions may prevent AD, but that remains a big question mark,” he noted. In addition, applications may sometimes “mobilize” topical prescriptive residual absorption and activity.

As for baths, he said, “avoidance of bathing to avoid drying out skin is a practice without evidence basis. Bathing also may have many benefits in active eczema.”

Bleach baths may enhance skin barrier function, reduce itch, and improve eczema, but the practice remains controversial, he continued. Authors of a systematic review and meta-analysis concluded that while bleach baths are effective in reducing the severity of AD, they do not appear to be more effective than water bath alone. Authors of a more recent study found that bleach baths did not normalize dysbiosis, “but that study did not compare outcomes to bathing without bleach,” Dr. Eichenfield noted.“My sense is there is some benefit to regular bathing, especially in children with moderate to severe AD, especially those with colonized or infected eczema.”

He advises clinicians to be aware of other “standard AD interventions” from around the world, including black tea wet dressings and green tea bath therapy.

Topical corticosteroids. These are “tried and true” for their anti-inflammatory properties and rapid response, relatively low cost, and large range of potency, he said. Potential problems include the burden of topical application and the potential for stinging/burning, atrophy, telangiectasias, adrenal axis suppression, and concerns about withdrawal phenomena. “Being a proponent of topical corticosteroids, but explaining reasonable and appropriate use can be challenging,” Dr. Eichenfield said. “Social media has influenced concerns about topical corticosteroids, with steroid addiction and withdrawal being concerns influencing discomfort with therapies.”

Make sure to measure outcomes. The suggested core outcome measure for recording clinical signs in AD clinical trials is the Eczema Area and Severity Index (EASI) score, he said. In clinical practice, Dr. Eichenfield favors body surface area (BSA) and the Validated Global Assessment scale (v-IGA) to measure signs of moderate to severe AD. “Documenting extent of disease makes a big difference in families understanding how severe their child’s disease is and how it is doing over time.” Alternatively, he recommends the Atopic Dermatitis Control Tool (ADCT) or the Recap of Atopic Eczema (RECAP) as tools assessing long-term disease control.

Familiarize yourself with nonsteroidal anti-inflammatory medications for care regimens. Options include topical calcineurin inhibitors (TCIs) such as tacrolimus and pimecrolimus; phosphodiesterase 4 (PDE-4) inhibitors such as crisaborole and roflumilast; the aryl-hydrocarbon receptor agonist tapinarof; and topical Janus kinase (JAK) inhibitors such as delgocitinib and ruxolitinib as well as others in development. “There is variable status around the world in terms of whether these nonsteroidal options are approved or not,” Dr. Eichenfield said. “Issues of use include cost, availability, side effects, and concerns about potential absorption. I think there’s an evolution in how much we rely on these instead of topical corticosteroids. They’re more commonly used in maintenance regimens rather than for remission induction.”

Dr. Eichenfield encouraged dermatologists to share information about and experiences with evolving treatment options for AD, “because when the studies are done, they are done as monotherapy. We must translate that into clinical practice and figure out how they fit in. Our exchange of information is critical.”

Dr. Eichenfield disclosed conflicts of interest from many pharmaceutical companies, including those with AD treatments.

TOPLINE:

Atopic dermatitis (AD) in early childhood is associated with an increased risk for inflammatory bowel disease (IBD) later in life, but atopic manifestations are generally not associated with IBD.

METHODOLOGY:

• Studies examining the link between atopy and IBD have yielded inconsistent results. Many of these studies included adults, introducing recall bias, or relied on physician diagnoses that might have overlooked mild cases.
• Researchers analyzed prospectively collected data on 83,311 children from two cohort studies, ABIS (1997-1999) and MoBa (1999-2008), who were followed up from birth until 2021 or a diagnosis of IBD.
• Information on parents was collected prospectively via questionnaires on any atopy their children might have developed by the age of 3 years. Atopy included conditions such as AD, asthma, food allergy, or allergic rhinitis.

TAKEAWAY:

• A total of 301 participants were diagnosed with IBD over 1,174,756 person-years of follow-up. By the age of 3 years, 31,671 children (38%) were reported to have any atopic manifestation.
• Children with AD at the age of 3 years demonstrated a significantly higher risk for IBD (pooled adjusted hazard ratio [aHR], 1.46), Crohn’s disease (pooled aHR, 1.53), and ulcerative colitis (pooled aHR, 1.78).
• Any atopic manifestation by the age of 3 years was not associated with a subsequent risk for IBD, Crohn’s disease, or ulcerative colitis, nor were analyses focused on early-life food-related allergy, asthma, and allergic rhinitis.

IN PRACTICE:

According to the authors, these findings suggested potential shared underlying causes between AD and IBD, which could help identify individuals at risk, and “a deeper understanding could significantly benefit the development of novel treatment approaches capable of effectively addressing both conditions, consequently enhancing patient outcomes.”

SOURCE:

This study, led by Tereza Lerchova, MD, PhD, Department of Pediatrics, Institute of Clinical Sciences, Sahlgrenska Academy, University of Gothenburg, Gothenburg, Sweden, was published online in The Journal of Pediatrics.

LIMITATIONS:

The findings of this study were mostly related to childhood-onset IBD instead of IBD in adult life. Lower participation in the MoBa study could limit generalizability to a broader population. In addition, there might have been lower participation from families without atopic manifestations.

DISCLOSURES:

The study was funded by the Swedish Society for Medical Research, Swedish Research Council, and ALF and supported by grants from the Swedish Child Diabetes Foundation, Swedish Council for Working Life and Social Research, Swedish Research Council, Medical Research Council of Southeast Sweden, JDRF Wallenberg Foundation, Linkoping University, and Joanna Cocozza Foundation.

Not everyone with AD treated with dupilumab gets clear or almost clear in clinical trials. The study by Cork and colleagues looked to see whether those patients who did not get to clear or almost clear were still having clinically meaningful improvement. To test this, the investigators looked at patients who still had mild or worse disease and then at the proportion of those patients at week 16 who achieved a composite endpoint encompassing clinically meaningful changes in AD signs, symptoms, and quality of life: ≥50% improvement in Eczema Area and Severity Index or ≥4-point reduction in worst scratch/itch numerical rating scale, or ≥6-point reduction in Children's Dermatology Life Quality Index/Infants' Dermatitis Quality of Life Index. Significantly more patients, both clinically and statistically significantly more, receiving dupilumab vs placebo achieved the composite endpoint (77.7% vs 24.6%; P < .0001). 

The "success rate" reported in clinical trials underestimates how often patients can be successfully treated with dupilumab. I don't need a complicated composite outcome to know this. I just use the standardized 2-point Patient Global Assessment measure. I ask patients, "How are you doing?" If they say "Great," that's success. If they say, "Not so good," that's failure. I think about 80% of patients with AD treated with dupilumab have success based on this standard.

Hand dermatitis can be quite resistant to treatment. Even making a diagnosis can be challenging, as psoriasis and dermatitis of the hands looks so similar to me (and when I used to send biopsies and ask the pathologist whether it's dermatitis or psoriasis, invariably the dermatopathologist responded "yes"). The study by Kamphuis and colleagues examined the efficacy of abrocitinib in just over 100 patients with hand eczema who were enrolled in the BioDay registry. Such registries are very helpful for assessing real-world results. The drug seemed reasonably successful, with only about 30% discontinuing treatment. About two thirds of the discontinuations were due to inefficacy and about one third to an adverse event.

I think there's real value in prescribing the treatments patients want. Studies like the one by Ameen and colleagues, using a discrete-choice methodology, allows one to determine patients' average preferences. In this study, the discrete-choice approach found that patients prefer safety over other attributes. Some years ago, my colleagues and I queried patients to get a sense of their quantitative preferences for different treatments. Our study also found that patients preferred safety over other attributes. However, when we asked them to choose among different treatment options, they didn't choose the safest one. I think they believe that they prefer safety, but I'm not sure they really do. In any case, the average preference of the entire population of people with AD isn't really all that important when we've got just one patient sitting in front of us. It's that particular patient's preference that should drive the treatment plan.

Some years ago, my colleagues and I queried patients to get a sense of their quantitative preferences for different treatments. Our study also found that patients preferred safety over other attributes. However, when we asked them to choose among different treatment options, they didn't choose the safest one. I think they believe that they prefer safety, but I'm not sure they really do. In any case, the average preference of the entire population of people with AD isn't really all that important when we've got just one patient sitting in front of us. It's that particular patient's preference that should drive the treatment plan.
