Background Psoriasis and psoriatic arthritis (PsA) are chronic inflammatory diseases that affect not only the skin and joints but also the cardiovascular system.Aim To investigate the relationship between epicardial adipose tissue (EAT) thickness and anthropometric measurements, laboratory parameters, and clinical variables in patients with psoriasis and PsA.Methods This cross-sectional study included 65 patients with psoriasis vulgaris (with or without PsA) and 54 healthy controls. Demographic,

Psoriasis is a chronic, immune-mediated skin disease with well-studied genetic and immunologic drivers. Substantial unexplained variability remains, however, in disease onset, severity, and treatment response. There is evidence that implicates the role of environmental and social determinants in these observed differences in psoriasis. We conducted a systematic review to synthesize the current evidence examining the relationship between external exposures, including air and chemical pollution, t

Background Psoriasis is recognized as a systemic inflammatory disease associated with metabolic dysregulation. Understanding these metabolic changes may reveal biomarkers to elucidate disease mechanisms and predict comorbidities. While previous studies have identified psoriasis-associated metabolites, findings are often limited by sample sizes and lack validation.Objectives To identify circulating metabolites associated with psoriasis, including disease severity and psoriatic arthritis. Further,

Background Palmoplantar psoriasis exhibits greater treatment resistance compared to other psoriatic plaques and presents clinical and histopathological overlap with palmoplantar eczema. This study aimed to investigate treatment resistance mechanisms in palmoplantar psoriasis and assess the contribution of IL-17, IL-23, and IL-36α to the differential diagnosis of palmoplantar psoriasis and eczema. Immunohistochemical levels of these cytokines were measured in paired acral and non-acral psoriatic

Psoriasis is a chronic, immune‑mediated skin disorder characterized by keratinocyte hyperproliferation, inflammatory infiltrates and systemic comorbidities. While genetic predisposition and immune dysregulation are established contributors, recent advancements in high‑throughput omics technologies have provided deeper insights into the molecular complexity of psoriasis. The present review synthesized findings from various omics layers, genomics, epigenomics, transcriptomics, proteomics, metabolo

The relative efficacy of methotrexate versus cyclosporine in the treatment of moderate-to-severe chronic plaque psoriasis remains controversial. This systematic review and meta-analysis evaluates the effectiveness of methotrexate compared to cyclosporine for psoriasis patients. From inception through April 2025, PubMed, Cochrane, Embase, and Google Scholar were searched for randomized controlled trials (RCTs) comparing methotrexate with cyclosporine in patients with chronic plaque psoriasis. A r

Objective We aimed to identify and characterize distinct subgroups of patients with psoriatic arthritis (PsA) based on their responses to the Assessment of SpondyloArthritis international Society Health Index (ASAS HI), using latent class analysis (LCA).Methods We performed an exploratory LCA on 17 dichotomous ASAS HI items in a cohort of patients with PsA (n = 90). Model adequacy was evaluated by log-likelihood, Akaike information criterion (AIC), Bayesian information criterion (BIC), entropy,

Background Psoriasis is one of the chronic inflammatory skin conditions, affecting about 2-3% of the world population. Steroidal treatment are only best choice of treatments, but it is often associated with side effects due to higher lipophilicity.Objectives In this work, a nanoparticle-loaded transdermal film was developed to maintain nanoparticle integrity in the skin.Methods Fluticasone propionate loaded chitosan nanoparticles (NPs) were developed, and their particle size, zeta potential, dru

Psoriasis is a chronic inflammatory skin disease in which the IL-23/Th17/IL-17 axis plays a central pathogenic role while also contributing to antifungal defence. IL-17-targeting biologics such as secukinumab and ixekizumab are increasingly used in its management. This study aimed to characterize changes in the diversity and composition of oral fungal and bacterial communities in psoriasis patients before and after treatment with IL-17 inhibitors. Oral swabs were collected from psoriasis patient

Background Data on the prevalence of sensitive skin in patients with chronic inflammatory skin diseases are lacking. The aim of this study was to address this gap.Methods This observational study included patients with psoriasis, atopic dermatitis or chronic hand eczema who attended the Unit of Dermatology of Ferrara and Messina, Italy, between June and December 2023. All participants completed a 10-item questionnaire for the diagnosis of sensitive skin (score range: 0-10). Participants were cla

Background Psoriasis is a chronic immune-mediated skin disease influenced by genetic, environmental, and lifestyle factors, with increasing burden among working-age adults.Objective To examine global trends in psoriasis prevalence among working-age adults, evaluate associations with lifestyle factors using a simplified Life's Essential 4 (LE4) index, and explore potential dietary causal relationships through Mendelian randomization (MR).Methods Global prevalence trends from 1990 to 2021 were ana

Objective To disentangle tobacco constituents in psoriasis, we contrasted nicotine exposure-proxied by the nicotine metabolite ratio (NMR)-with smoking intensity (cigarettes per day, CPD) and evaluated cross-ancestry effects.Methods This study applied multivariable Mendelian randomization (MR) jointly modeling genetically proxied NMR (instrumented using variants from a European-ancestry GWAS) and CPD to estimate their independent effects on liability to psoriasis and psoriatic arthritis (PsA). C

Background B-cell depleting therapies (BCDT), including ocrelizumab, ofatumumab, and ublituximab, are highly effective disease-modifying therapies for multiple sclerosis (MS). Several case reports have raised concerns about new-onset or exacerbation of psoriasis under BCDT.Objectives This article aims to analyze clinical characteristics, treatment courses, and outcomes of MS patients who developed or experienced worsening of psoriasis during BCDT.Design This retrospective, multicenter analysis i

Psoriasis is a chronic immune-mediated disease with global prevalence of 2-3% that is associated with significantly reduced quality of life (QoL) and worsened mental health. Despite this, there is a lack of research in African psoriasis populations, with no modern epidemiological studies conducted in Kenya to examine these factors. This study aims to identify demographic and clinical features associated with dermatology-related QoL and mental health among psoriasis patients enrolled in the newly

Abstract Background Early identification of treatment response is clinically important in psoriasis management, as it may facilitate timely treatment modification and reduce exposure to ineffective therapies. Although early improvement in the Psoriasis Area and Severity Index (PASI) has been associated with long term outcomes for individual therapies, a broadly applicable early PASI threshold across different treatment modalities in real-world practice remains unclear. Objectives To evaluate

Tobacco smoking is viewed as a behavioral risk factor for psoriasis initiation and progress, even among those undergoing biologic treatment. However, evidence regarding the association between tobacco smoking and treatment response to biologics among patients with psoriasis is limited. This study aimed to explore the impact of tobacco smoking on the efficacy of biologic treatment in patients with psoriasis. Patients with psoriasis undergoing biologic treatment were recruited from 2022 to 2024 at

Introduction The rising incidence of inflammatory skin diseases, including psoriasis, has necessitated new treatment approaches. This paper focuses on the development of a hibiscetin-impregnated nanogel that reduces the severity of skin inflammation.Methods Imiquimod (IMQ) was used to induce psoriasis-like inflammation in animal models, and the nanogel's worthiness was compared. Nanogel was prepared in different concentrations of hibiscetin, namely F1 (1) and F2 (2), and characterized in terms o
