Atopic dermatitis (AD) is a chronic inflammatory skin condition characterized by fluctuating disease activity. Exacerbations of AD signs and/or symptoms, or flares, have a significant impact on patient quality of life and may require modification or escalation of treatment. However, research into preventing and managing flares may be hampered by the lack of consensus on a clear, clinically relevant, measurable definition of flare. This narrative review provides an overview of disease flare frameworks established through previous systematic literature reviews, flare definitions proposed by American and European guidelines, as well as those used in randomized controlled trials and observational studies published between January 2014 and September 2024. It identifies a range of flare definitions in use in the literature, the majority of which are based on clinician-reported outcomes, with very few referring to the patient perspective. Given the highly individualized experience of disease flare in patients with AD, incorporating the perspective of patients, alongside established measures of disease activity, is vital for creating and validating a definition that is clinically relevant.

Background
Ethnic differences in the clinical and molecular features of many immune-mediated dermatoses have been reported, including psoriasis vulgaris and generalized pustular psoriasis. Palmoplantar pustulosis (PPP) is a chronic and relapsing inflammatory skin disease manifesting as crops of sterile pustules over an erythematous base on the palms and soles. To date, ethnic differences in PPP have been rarely studied.
Objectives
To compare the differences in epidemiology, genetic background, clinical manifestations, treatment patterns, and responses among patients with PPP across different ethnicities.
Methods
A systematic review was performed in accordance with the 2020 PRISMA guidelines, including a search across four bibliographical databases, including articles published between the earliest available date until 1 February 2025. Articles were reviewed independently by two assessors. Any discrepancies were addressed and resolved through discussion. A narrative synthesis was performed owing to heterogeneity. The study protocol was registered in INPLASY (INPLASY202530108). No funding was received.
Results
Of 2250 studies screened, 101 studies were included. Among them, 46 studies (42 cohort studies, 1 case-control, and 3 case series) involving 216,257 patients described the clinical characteristics of PPP, with 13 and 14 cohort studies reporting on the epidemiological data and treatment type/response of PPP, respectively. Incidence and prevalence rates of PPP were higher among East Asians, especially in Japanese populations. While PPP is a female-predominant disease worldwide, more men are affected in Asia, likely owing to a lower prevalence of smoking among Asian females. Mutations in IL36RN, CARD14, and different HLA alleles contribute to the genetic landscape of PPP across ethnicities. PPP with preceding vesicles (type A) seemed more common in Asians, and type B (without preceding vesicles) is more common in non-Asians. Asians with PPP had less concurrent psoriasis vulgaris and psoriatic arthritis, as well as lower rates of smoking, obesity, celiac disease, and thyroid disease, while metal allergies were more common. Plantar-only or unilateral involvement were more frequent in non-Asians, whereas nail involvement and synovitis-acne-pustulosis-hyperostosis-osteitis (SAPHO) syndrome/pustulotic arthro-osteitis (PAO) were more common in Asians. Among conventional treatment modalities, acitretin, colchicine, and tonsillectomy seemed more effective for Asians. Biologics were less commonly used in Asia, with ethnic-related differences in treatment response noted across classes.
Conclusions
This systematic review illustrated notable differences in genetic profiles, clinical features, and therapeutic responses of PPP across ethnicities. Although limited by study size and heterogeneity, these findings could enhance our understanding of ethnic-specific PPP traits. Th

Background
Nail psoriasis can have a substantial negative impact on both the physical and emotional well-being of patients, and is a risk factor for psoriatic arthritis. Achieving complete clearance of nails in addition to skin is therefore an important treatment goal.
Objectives
We aimed to evaluate concurrent complete skin and nail clearance in patients with moderate-to-severe plaque psoriasis treated with bimekizumab or active comparators.
Methods
Data were analyzed from the BE SURE and BE VIVID phase III trials, their open-label extension BE BRIGHT, and the BE RADIANT phase IIIb trial and its open-label extension. Included patients had baseline modified Nail Psoriasis Severity Index (mNAPSI) >0 and entered their respective open-label extension. Proportions of patients achieving complete skin (PASI 100; 100% improvement from baseline in Psoriasis Area and Severity Index) and nail (mNAPSI 0) clearance at the same time are reported for bimekizumab- and active comparator-treated patients during controlled trial periods, and in the long term for continuous bimekizumab-treated patients and those switching from comparators. Data are reported using modified non-responder imputation.
Results
At the end of comparator-controlled periods, 45.8% of bimekizumab (N = 151) versus 18.3% of adalimumab (N = 91) patients (BE SURE week 24), 51.1% of bimekizumab (N = 169) versus 26.5% of ustekinumab (N = 92) patients (BE VIVID week 52), and 63.3% of bimekizumab (N = 182) versus 36.1% of secukinumab (N = 155) patients (BE RADIANT week 48) achieved PASI 100 and mNAPSI 0. Following long-term treatment, 57.7% of adalimumab switchers/49.1% of continuous bimekizumab patients (BE SURE/BE BRIGHT year 4), 52.2% of ustekinumab switchers/48.3% of continuous bimekizumab patients (BE VIVID/BE BRIGHT year 4), and 51.9% of secukinumab switchers/57.4% of continuous bimekizumab patients (BE RADIANT year 3) achieved PASI 100 and mNAPSI 0.
Conclusions
Numerically higher proportions of bimekizumab-treated patients achieved concurrent complete skin and nail clearance versus adalimumab, ustekinumab, and secukinumab. Clearance rates increased following switch to bimekizumab, and were sustained long-term in both switchers to bimekizumab and continuous bimekizumab-treated patients. [Graphical abstract available.]

Moderate-to-severe erythrodermic psoriasis was characterized by a higher inflammatory burden (median neutrophil-to-lymphocyte ratio 4.11 vs 2.70, <i>p</i> < 0.001), more frequent fever (88% vs 41%, <i>p</i> < 0.001), greater edema severity (16% vs 1.4%, <i>p</i> < 0.001), lower albumin and higher calcium levels (both <i>p</i> < 0.001), and longer hospitalization (median 26 vs 20 days, <i>p</i> = 0.005). After adjustment for age and sex, moderate-to-severe cases required systemic therapy roughly twice as often as mild cases (odds ratio 2.21, <i>p</i> < 0.05). Of seven machine-learning algorithms, the Artificial Neural Network yielded the highest mean validation area under the curve. The SHAP analysis highlighted the ten most influential predictors adopted from the Artificial Neural Network—edema, edematous erythema (defined as the combination of both redness and swelling of the skin), fever, albumin, neutrophil-to-lymphocyte ratio, serum calcium, white blood cell count, acute-phase reactants (C-reactive protein or erythrocyte sedimentation rate), pruritus, and superficial lymphadenopathy—and these were converted to integer points to form the bedside score.

背景:红皮病型银屑病是一种罕见的银屑病亚型,具有广泛的皮肤病变,一些患者出现严重的全身症状。目的:我们旨在开发和验证一个人工智能驱动的模型,通过整合临床和实验室指标来准确分类红皮病型银屑病的严重程度。方法:回顾性队列研究于2005-22年在北京协和医院进行。采用k-均值聚类法将患者分为轻度组和中度至重度组。在输入缺失值之后,我们训练了7种候选算法——k近邻、人工神经网络、随机森林、极端梯度增强、支持向量机、贝叶斯分类器和逻辑回归——使用重复的、分层的10倍交叉验证和3次重复(10 × 3 CV);性能通过接收器工作特性曲线下的平均面积进行总结。特征重要性的评估使用SHAP (Shapley加性解释),这是一种量化每个特征对个体模型预测贡献的博弈论方法,十个指标被纳入诊断评分系统。根据交叉验证的受试者工作特征曲线上的约登指数选择轻度/中度至重度病例分类的最佳截止值。结果:260例筛查记录中,242例红皮病患者符合研究标准。组织学证实108例为牛皮癣,其余患者根据临床表现和病史诊断。K-means聚类将94例患者分配到中度至重度组,148例患者分配到轻度组。中重度红皮病银屑病的特点是较高的炎症负担(中位中性粒细胞与淋巴细胞比值为4.11 vs 2.70, p)。结论:EPICS模型是评估红皮病银屑病严重程度的有力工具,基于易于获得的临床和实验室指标提供精确的分类。然而,其在临床实践中的有效性需要通过进一步的研究来进一步验证。

<div><h3>Background</h3><p>Erythrodermic psoriasis (EP) is a severe and rare variant of psoriasis. Clinical features include scaling and erythema affecting more than 75% of body surface area, associated with systemic symptoms such as lymphadenopathy, arthralgia, fever, fatigue, dehydration, serum electrolyte disturbances, and tachycardia, making this condition a potentially life-threatening disease. Differential diagnosis can be challenging, encompasses atopic dermatitis, cutaneous adverse drug reaction, and advanced cutaneous lymphoma. Following a correct diagnostic framing, appropriate systemic treatment must be initiated. Unfortunately, there are no recent up-to-date guidelines and standardized treatment options for EP are still lacking.</p><h3>Objective</h3><p>To review the current reported systemic treatment options for EP.</p><h3>Methods</h3><p>This systematic review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, and based on a search in MEDLINE, PubMed, Scopus, and Cochrane Library for articles in English from first available publication to 9 November 2024.</p><h3>Results</h3><p>In all, 145 studies were included in the review. Case reports and case series are the main available work, reporting heterogeneous outcomes and effectiveness with nonbiologic and biologic systemic agents. Among non-biologic systemic treatments, methotrexate and cyclosporin are the most widely reported as treatment for EP, showing clinical response in over 60% of cases, with cyclosporine offering a faster onset of action and being suitable for acute management. Available randomized controlled trials include patients with EP treated with etretinate, infliximab, certolizumab-pegol (CZP), Ixekizumab, guselkumab, risankizumab, and deucravacitinib. However, these trials were not specifically designed for erythrodermic psoriasis, and the sample size of EP patients included is limited, resulting in reduced statistical power and limiting the reliability of the findings. Among TNF-α inhibitors, infliximab is the most reported agent, with data on 103 patients. Certolizumab pegol (CZP) also showed promising results, with PASI 75 achieved in over 80% of patients at 52 weeks. A retrospective analysis comparing infliximab, adalimumab, etanercept, ustekinumab, and efalizumab found TNF-α inhibitors to be superior to other biologic classes. Regarding IL-17 inhibitors, secukinumab is the second most frequently studied biologic, with 93 patients reported. It demonstrated rapid efficacy, achieving PASI 75 in more than 80% of patients by week 8. A head-to-head comparison with ixekizumab showed comparable outcomes. Among IL-23 inhibitors, risankizumab led to PASI 90 in over 75% of patients at week 16, suggesting high efficacy despite more limited data.</p><h3>Conclusions</h3><p>Non-biologic systemic drugs appear to be a rational first-line therapy, with cyclosporine showing good results in managing the acute ph

However, these trials were not specifically designed for erythrodermic psoriasis, and the sample size of EP patients included is limited, resulting in reduced statistical power and limiting the reliability of the findings. Among TNF-α inhibitors, infliximab is the most reported agent, with data on 103 patients. Certolizumab pegol (CZP) also showed promising results, with PASI 75 achieved in over 80% of patients at 52 weeks. A retrospective analysis comparing infliximab, adalimumab, etanercept, ustekinumab, and efalizumab found TNF-α inhibitors to be superior to other biologic classes. Regarding IL-17 inhibitors, secukinumab is the second most frequently studied biologic, with 93 patients reported. It demonstrated rapid efficacy, achieving PASI 75 in more than 80% of patients by week 8. A head-to-head comparison with ixekizumab showed comparable outcomes. Among IL-23 inhibitors, risankizumab led to PASI 90 in over 75% of patients at week 16, suggesting high efficacy despite more limited data.</p><h3>Conclusions</h3><p>Non-biologic systemic drugs appear to be a rational first-line therapy, with cyclosporine showing good results in managing the acute ph","PeriodicalId":7706,"journal":{"name":"American Journal of Clinical Dermatology","volume":"26 6","pages":"877 - 893"},"PeriodicalIF":8.8,"publicationDate":"2025-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s40257-025-00977-1.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144939457","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Lichen simplex chronicus (LSC), also known as neurodermatitis, is a common chronic pruritic dermatosis defined by lichenified plaques resulting from persistent scratching. Though often secondary to underlying dermatologic, systemic, or psychological triggers, LSC represents a distinct clinical entity with significant morbidity. The hallmark itch-scratch cycle contributes not only to visible skin changes but also to substantial sleep disruption, emotional distress, and functional impairment. Psychological stress, anxiety, and depression are frequent comorbidities and can further perpetuate disease chronicity. This review provides a comprehensive summary of the evolving understanding of LSC, from its neuroimmune-driven pathogenesis to the wide spectrum of therapeutic strategies currently available. In addition to topical corticosteroids, novel approaches including immunomodulators, neuromodulators, Janus kinase (JAK) inhibitors, and biologics are being increasingly explored. Procedural therapies such as cryotherapy, fractional laser resurfacing, and botulinum toxin injections, have also emerged as valuable tools, particularly in treatment-refractory cases. Recent insights into type 2 inflammation and dysregulated sensory pathways have informed the rationale for these targeted strategies. In anatomically sensitive areas such as the genital region, where topical agents may be poorly tolerated, systemic treatments may be required. Given this complexity, individualized, multimodal treatment plans are critical to optimizing management and improving quality of life (QoL) in patients with LSC. By synthesizing current data on pathophysiology, diagnosis, and both established and emerging therapies, this review aims to guide clinicians in optimizing care for patients with LSC and addressing its far-reaching psychosocial burden.

The growing availability of targeted immunomodulatory therapies has transformed the treatment landscape for chronic inflammatory skin diseases. However, treatment selection remains largely empirical, often guided more by trial-and-error and insurance mandates than by an individual patient’s underlying disease biology. This disconnect between therapeutic strategy and the need to address and calibrate for patient molecular heterogeneity undermines clinical outcomes and contributes to inefficiency in care delivery. Precision medicine offers a solution by tailoring diagnosis and treatment to the molecular and cellular features of each patient’s skin disease. In this Current Opinion, we outline key clinical contexts where precision approaches can be transformative: diagnostic ambiguity, selecting treatments for an established diagnosis, and selecting treatments without a defined diagnosis or disease mechanism. We highlight advances in precision techniques such as single-cell RNA sequencing and spatial transcriptomics that enable more refined skin disease classification and accurate prediction of drug response. Although several challenges remain before these techniques can be widely adopted, such as limited biomarker validation, high costs, and a lack of breadth in research cohorts, we argue that their potential benefits, for patients, clinicians, and the broader field of dermatologic care, substantially outweigh the associated costs. We advocate for expanded funding, population-based research, and scalable diagnostics to successfully integrate precision medicine into dermatology. By combining molecular phenotyping with traditional clinicopathologic diagnosis, precision medicine can reduce therapeutic inefficiency, improve patient outcomes, and redefine care paradigms in chronic inflammatory skin disease.

As women of childbearing potential constitute a considerable portion of the total psoriasis population, dermatologists must consider both the clinical and psychosocial implications of psoriasis when treating these patients. This review summarizes key clinical considerations when treating women of childbearing potential with psoriasis, regarding family planning, pregnancy, and the postpartum period, aiming to assist in identifying common concerns within this population. Many women report initiating the discussion on family planning but having limited access to information. Concerns about the impact of psoriasis and its treatment on fertility, pregnancy, and lactation are common, and lack of adequate information can lead to irrevocable decisions. Despite conflicting results, current evidence suggests a potential negative correlation between moderate-to-severe psoriasis and fertility. Studies on adverse maternal and neonatal events associated with psoriasis show inconsistent outcomes and should be communicated with caution. With the increase in available treatment options during pregnancy and lactation, particularly in cases of severe psoriasis, personalized treatment plans are becoming more achievable, allowing dermatologists to better address the needs of their patients. The majority of patients can be treated during pregnancy with topical treatments or ultraviolet-B irradiation. While the general recommendation is to stop systemic treatment before conception, decisions should be made on an individualized basis. If treatment cannot be discontinued, tumor necrosis factor-α inhibitors and cyclosporine can be used. It is essential to inform parents of the additional risks associated with live or live-attenuated vaccines in cases where the mother has received systemic treatment during pregnancy and to delay vaccinations accordingly.

Alopecia areata (AA) is an autoimmune disease that is characterized by nonscarring hair loss of the scalp, face, and/or body. Three therapies have been approved for the treatment of severe AA; however, there are several different approaches for defining disease severity. Therefore, severity assessment tools are helpful in determining the appropriate treatment approach and evaluating treatment response in patients with AA. This vodcast discusses tools for assessing AA severity, including the Severity of Alopecia Tool, AA Scale, and AA Severity and Morbidity Index. It is suggested that severity assessments should include factors beyond just scalp hair loss, with the AA Scale including secondary clinical features, such as involvement of eyebrows and eyelashes. Moreover, AA can significantly impact patient’s quality of life; therefore, measuring the psychosocial impacts of AA is as important as measuring the physical effects. Some of the measures to assess the negative impact on the quality of life of patients with AA include the Dermatology Life Quality Index, Alopecia Areata Symptom Impact Scale, and Children's Dermatology Life Quality Index. Behavioral changes due to AA could also be considered when assessing psychosocial impacts, particularly for adolescents, who may experience bullying, which can lead to school avoidance, anxiety, and depression. In summary, when assessing severity of AA to inform treatment decisions, clinicians should be guided by evidence-based tools, with additional consideration of factors beyond scalp hair loss, such as impairment in activity, mental health, and wellbeing.
