Management of CP comprises treatment of the underlying disease as well as topical and systemic therapies. Treating CP needs to be targeted, multimodal and performed in a step-wise procedure requiring an interdisciplinary approach.

Different exposome factors, including hormonal and family factors, have been suggested to influence acne. Obesity is an increasingly observed condition worldwide, and is considered as a public health problem by the World Health Organization. Recently, a high body mass index has been identified as an acne severity risk factor in adolescents. A group of 5 dermatologists from different institutions and private practices from France involved in the research and clinical fields of acne -analysed recent literature on \"obesity and acne\" focusing on epidemiology, the pathogenesis of acne and obesity, as well as the management of acne in obese patients. The authors selected, prior to their discussion in November and December 2024 and again in March 2025, and discussed 52 articles concerning acne and obesity published since 2000 and available from the PubMed database. The authors agreed that, considering these common metabolic features, managing both acne and obesity in parallel and helping patients through a global approach including dermatological, endocrinal, psychological and nutrition, as well as lifestyle support is mandatory, and may allow for the improvement of both acne and obesity. Moreover, in order to allow dermatologists to manage acne in obese patients in the most efficient way, the authors developed and propose a decision tree. The authors consider that acne in obese patients is not a fatality, and taking care of acne should not be considered an isolated task in this specific patient population.</p>","PeriodicalId":6944,"journal":{"name":"Acta dermato-venereologica","volume":"105 ","pages":"adv43945"},"PeriodicalIF":3.7,"publicationDate":"2025-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12382383/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144938285","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Patients with psoriasis initiating an interleukin-17 inhibitor (n = 36) or adalimumab (n = 24) were enrolled. Patients attended visits at baseline, week 12, and week 52, during which skin and mucosal swabs, and faecal and blood samples were collected. Baseline oral Candida albicans colonization with no clinical symptoms was associated with an increased risk of oral candidiasis during the first year of interleukin-17 inhibitor therapy, with no cases of oral candidiasis observed in the adalimumab group. Gut inflammation, measured by faecal calprotectin, remained stable in both the adalimumab and interleukin-17 inhibitor group. Colonization with Staphylococcus aureus did not change during treatment. It was found that interleukin-17 inhibitors induced an anti-inflammatory state and potentially more active toll-like receptor 3-mediated antiviral responses compared with adalimumab.

The annual point prevalence, incidence, and years lived with disability of alopecia areata from 204 countries and regions from 1990-2021 were extracted. Subgroup analyses based on gender, age, global, national, regional, sociodemographic index, and World Bank income were conducted. From 1990-2021, age-standardized prevalence, incidence, and years lived with disability of alopecia areata globally show a decreasing trend, with females dominating. There was a reduction in the disease burden in high sociodemographic index regions, but alopecia areata in general did not reflect a concentration in certain regions and was more equally distributed. Decomposition analysis revealed that population growth was the major contributor to the burden of alopecia areata, followed by population ageing. Patients with alopecia areata before the age of 14 were associated with anxiety disorders and other psychological disorders, but patients after the age of 14 were not associated with the onset of these disorders. Also, atopic dermatitis has been associated with alopecia areata.
