Yet, as underscored by the systematic review by Preis et al.,<span><sup>1</sup></span> medical research and clinical practice have too often marginalized sex- and gender-based variations, creating a one-size-fits-all approach. This newly published work dives into how both biological (sex) and sociocultural (gender) factors alter disease trajectories, therapeutic outcomes and risk profiles in dermatological conditions such as psoriasis and atopic dermatitis.</p><p>A noteworthy finding of this systematic review is the discrepancy in treatment success and adverse events between men and women. In psoriasis, for instance, female sex was frequently linked to increased side effects,<span><sup>2</sup></span> as also shown in our more recent work from Switzerland.<span><sup>3</sup></span> Paradoxically, lower treatment response was seen in other studies.<span><sup>4</sup></span> These observations imply that weight-based dosing, hormonal milieu, psychosocial variables or adherence may skew women's clinical outcomes.

Moreover, insufficient patient-level knowledge about psoriasis, as well as lack of clinical studies with safety data in pregnancy, is frequently cited as barriers. This delay can perpetuate the underutilization of potentially beneficial treatments in women, while men—though less likely to have childbearing concerns—may face other healthcare hurdles such as reluctance to seek early dermatologic consultation.</p><p>As the authors rightly note, existing data predominantly conflate ‘sex’ and ‘gender’ into a single category, making it difficult to measure how purely biological differences (e.g., hormonal fluctuations and body mass index) interact with social and psychological factors (e.g., stigma and cultural norms).

I remember, as a resident dermatologist during the mid-1990s, we treated most of our severe psoriasis patients by rotating low-to-medium efficacy therapies: topical treatments (salicylic acid, corticosteroids, dithranol) phototherapy, acitretin and less frequently cyclosporine or methotrexate. Many patients regularly spent weeks in the hospital, and treatment success was usually partial and temporary, lasting for only a few months. The introduction of first-generation biologics marked a significant shift in the management of psoriasis. Methotrexate, which was used as the comparator in clinical trials, became the standard non-biological treatment, and patients began to experience longer more complete remissions. During the last decade, several novel biologics entered the psoriasis field, which showed clear superiority over both conventional and previous-generation biologics. Some biologics have been registered even as first-line treatments, theoretically enabling the early introduction of highly effective therapy. These advancements have led to more ambitious treatment goals by both doctors and patients. Today, even a cure—that is long-term remission off-treatment—seems scientifically realistic.<span><sup>1</sup></span></p><p>Notwithstanding these groundbreaking achievements, dermatologists still face considerable challenges in providing optimal care for psoriasis patients.

The authors provide several arguments for the important role of MRGPRX2 in chronic spontaneous urticaria, atopic dermatitis, rosacea, psoriasis, chronic pruritus, and chronic prurigo.<span><sup>2</sup></span> Most importantly, an increased expression of MRGPRX2 agonists has been identified in all of these diseases. The majority of these agonists are either neuropeptides, such as substance P and vasoactive intestinal polypeptide, or peptides involved in antimicrobial defence (e.g. cortistatin, β-defensins and LL-37).<span><sup>3</sup></span> Many resident skin cells such as keratinocytes, sensory nerves, and macrophages, but also inflammatory cells recruited to sites of chronic skin inflammation can release MRGPRX2 agonists. This may also shed some light on the potential of skin MCs to contribute to non-allergic skin diseases: Although the receptor has also been detected in some other cell types, by far the highest expression of MRGPRX2 is found on skin MCs.<span><sup>4</sup></span> Since all MRGPRX2 agonists can activate MCs to release proteases, cytokines, and histamine,<span><sup>5</sup></span> the observed increase of MRGPRX2 agonists in various inflammatory skin diseases is likely to contribute to at least some aspects (e.g. pruritus) of the respective skin diseases by activating and degranulating skin MCs. Another argument of Kumar et al. for an important involvement of MRGPRX2 is the observed increased sensitivity to provocation with exogenous and endogenous MRGPRX2 agonists in patients with chronic spontaneous urticaria. This increased sensitivity to MRGPRX2 agonists may be due to the increased number of MRGPRX2 expressing cells (i.e. mast cells) observed in the skin of patients with chronic spontaneous urticaria, but also in many other chronic inflammatory skin diseases.</p><p>Several MRGPRX2 antagonists have already been tested in preclinical models in vitro and in humanized mouse models in vivo, and have been shown to effectively block MRGPRX2 agonist-mediated activation of MCs.<span><sup>2</sup></span> Currently ongoing (NCT06077773, NCT06050928) and further planned clinical trials investigating the efficacy of MRGPRX2 antagonists in chronic spontaneous and chronic inducible urticaria will provide insi","PeriodicalId":17351,"journal":{"name":"Journal of the European Academy of Dermatology and Venereology","volume":"39 3","pages":"451-452"},"PeriodicalIF":8.4,"publicationDate":"2025-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/jdv.20541","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143481339","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
