Background and objective Psoriatic arthritis (PsA) is an inflammatory, chronic and progressive musculoskeletal disease associated with psoriasis. The validation of the Spanish version of the Psoriatic arthritis UnclutteRed screening Evaluation (PURE-4) questionnaire has been published previously. The present analysis studied the performance of the PURE-4 questionnaire for the early detection of PsA one year before its diagnosis.Materials and methods This was an observational multicenter study, i

Background Given the proinflammatory cascade elicited by tumor necrosis factor-α (TNF-α) in psoriasis, multiple TNF-α-targeted biologics have been developed for psoriasis treatment. Although systemic macromolecular biologics are widely used, a crucial therapeutic gap remains for mild-to-moderate psoriasis, underscoring an unmet need for more effective topical drugs suppressing TNF-induced inflammatory signaling.Objective To identify a novel potent natural small-molecule drug suppressing TNF-indu

Background Psoriatic disease has a complex effect on bone metabolism, resulting in both pathological bone formation and bone resorption. However, microstructural changes in cortical and trabecular compartments remain poorly understood. The aim of this study was to investigate the prevalence and determinants of bone microarchitectural damage in patients with psoriatic disease.Methods We performed a cross-sectional study in patients with psoriasis (PsO), psoriatic arthritis (PsA) and age-matched h

Background Skin is the largest organ of the human body. It continuously encounters environmental toxicants, including airborne pollutants, which may induce many skin disorders, such as psoriasis. However, evidence on the association between airborne pollutants and psoriasis prevalence in China remains limited.Methods We used nationwide inpatient diagnostic data on psoriasis from 2021 to 2023, encompassing 149 744 cases across 31 provinces, municipalities, and autonomous regions in China, along w

Introduction Biologic therapies have transformed the management of moderate-to-severe psoriasis but are associated with long-term treatment burden and substantial healthcare costs. Dose spacing, defined as extending dosing intervals in patients with controlled disease, has emerged as a potential optimization strategy. However, data on real-world implementation and clinician perspectives remain limited.Methods We conducted a national, cross-sectional survey among Portuguese dermatologists experie

This cross-sectional study aimed to determine the detectability of a panel of 92 inflammatory biomarkers in tape strips from the skin of patients with inflammatory skin diseases, and whether this depended on the number of tape strips taken. Furthermore, the biomarker levels in the patients were compared with those in healthy controls. Eight consecutive uniform tape strips (each 3.8 cm²) were obtained from 2 adjacent skin sites from 8 atopic dermatitis, contact dermatitis, and psoriasis patients,

Photosensitive presentations of psoriasis are often under-recognized and may closely mimic other photodistributed dermatoses. We report the case of a 39-year-old male patient with no history of other photodermatoses who developed a progressive, non-pruritic rash, localized in sun-exposed skin areas, with marked exacerbation after phototherapy. Pronounced photosensitivity and atypical lesion distribution, involving the malar and nasal regions, complicated the initial differential diagnosis betwee

Objective To evaluate the long-term efficacy of interleukin (IL)-17A inhibition with secukinumab on structural bone changes and clinical outcomes in psoriatic arthritis (PsA).Methods We conducted a phase-IV non-interventional study on adult patients with active PsA using high-resolution peripheral quantitative CT (HR-pQCT) and MRI of the hand over 48 months. All participants received secukinumab treatment and were followed up according to clinical practice, with repeated HR-pQCT and MRI. Number

Background: Psoriasis is a chronic systemic inflammatory disease with established extra-cutaneous manifestations. While the association between uveitis and spondyloarthritis (SpA)-related disorders is well recognized, the incident risk of uveitis among broader psoriasis populations remains inadequately defined due to methodological limitations and inconsistent findings across previous studies. We aimed to estimate the incidence of uveitis in a large, nationwide population-based cohort and identi

Psoriasis is a chronic, inflammatory skin disease occurring worldwide that significantly affects patients' quality of life. This common skin condition is characterized by abnormal hyperplasia of keratinocytes, which leads to the formation of raised, scaly plaques, typically located on the head, elbows, knees, and lumbar region. Psoriasis usually requires long-term drug therapy, which aims not only to combat skin symptoms but also to improve quality of life. Although topical treatments, systemic

Background Psoriasis is a persistent, chronic autoimmune skin disease that affects around 2% of the global population. Conventional therapies often exhibit limited efficacy, systemic side effects, and poor patient compliance due to long-term treatment needs.Materials & methods This study focused to develop and optimize a sulfasalazine-loaded microemulsion (SSZ-ME) for topical delivery to enhance skin penetration and therapeutic efficacy in psoriasis. Pseudo-ternary phase diagrams were prepar

The aggregate index of systemic inflammation (AISI), calculated from monocyte, neutrophil, lymphocyte, and platelet counts, is a blood-count-derived composite marker of systemic inflammation. This cross-sectional study aimed to examine the association between AISI and the prevalence of psoriasis among U.S. adults. The dataset was obtained from the National Health and Nutrition Examination Survey (NHANES) database from 2003 to 2006 and from 2009 to 2014. The relevant covariates were adjusted duri

Psoriasis is a chronic inflammatory skin disease, and previous studies among Western populations have suggested an increased risk of cardiovascular events in patients with psoriasis. However, evidence from Asian populations remains limited. We evaluated the risk of major adverse cardiovascular events (MACE) in patients with psoriasis compared with patients who have atopic dermatitis (AD) using a large-scale administrative claims database from Shizuoka, Japan. We conducted a cohort study using th

Background Biologic therapies have transformed psoriasis management, and their incorporation into Brazil's public healthcare system (SUS) in 2019 expanded access nationwide. However, real-world utilization and perceptions remain incompletely understood.Objectives To evaluate perceptions, barriers, and prescription patterns regarding biologic therapy among Brazilian dermatologists and patients five years after universal incorporation, while quantifying the prevalence of undertreatment.Methods We

Background The clinical definition of moderate psoriasis is debated, affecting treatment eligibility and patient outcomes.Objective A panel of Italian dermatologists aimed to propose practical criteria to define moderate psoriasis, based on a comprehensive literature review and clinical experience.Methods The panel reviewed publications between 2016 and 2024 focusing on key severity scores, including the Psoriasis Area and Severity Index (PASI), Body Surface Area (BSA), Dermatology Life Quality

Interleukin-23 (IL-23) inhibitors represent a major advance in the management of moderate-to-severe plaque psoriasis, grounded in the central pathogenic role of the IL-23/Th17 axis. By selectively targeting the p19 subunit, guselkumab, risankizumab, and tildrakizumab effectively suppress disease-driving inflammation while preserving IL-12-mediated host defence. Pivotal randomized trials have demonstrated high levels of skin clearance, durable efficacy, and favourable safety profiles. Nevertheles
