Introduction Cardiovascular disease is a leading co-morbidity in psoriasis patients. The cutaneous benefits of biologic therapies for severe plaque psoriasis are well-established, but the impact of biologics on major adverse cardiovascular events (MACE) in psoriatic patients requires further elucidation. This study aimed to investigate the impact of biologic therapies on the risk of MACE in patients with chronic plaque psoriasis.Methods We conducted a systematic review and meta-analysis on 10 Ma

Mitochondrial structural and functional changes accompany psoriasis, yet the mitochondrial response to psoriatic inflammation in keratinocytes and fibroblasts remains unexplored. In this study, we investigated the effect of psoriasis-like inflammation (PLI) induced by a cytokine cocktail (interleukin (IL)-17A, IL-22 and tumour necrosis factor (TNF)-α) on mitochondrial network morphology and function in cultured keratinocytes (HaCaT) and fibroblasts (BJ-5ta). In both cell types, PLI triggered the

Background Psoriasis is a chronic inflammatory skin disease often associated with obesity and metabolic dysfunction, which may worsen disease severity. Glucagon-like peptide-1 (GLP-1) receptor agonists, such as semaglutide, have shown metabolic and anti-inflammatory effects, but their impact on psoriasis in non-diabetic patients with obesity remains unclear.Objective To evaluate the effects of a six-month semaglutide treatment on psoriasis severity and clinical, metabolic, inflammatory, and psyc

Purpose To seek recommendations from a panel of experts in psoriatic arthritis (PsA) on the current management challenges, local practices, and role of interleukin (IL)-17 inhibitors in the United Arab Emirates (UAE) using evidence from phase III trials as background.Methods Nine rheumatologists who treat PsA in the UAE completed a structured survey and attended a meeting to discuss topics/issues identified in the survey. A literature search was performed to identify phase III randomized trials

Psoriasis (Pso) is a chronic inflammatory skin disease driven by T helper 17 (TH17) cells, with several clinical subtypes. While self-reactive immune responses have been observed, the role of autoantigens in Pso remains unclear. Using immunopeptidomics, we identified serpin family B member 3 (SERPINB3) and SERPINB4 as candidate autoantigens in Pso skin. In a mouse model, the SERPINB3 ortholog Serpinb3b enhanced inflammation, promoted tissue-resident memory T cells, and skewed immunity toward a T

Objective The concept of severity in psoriatic arthritis (PsA) remains inconsistently defined, often conflated with disease activity. This scoping review aimed to explore how severity has been defined in the PsA literature and to identify criteria used to characterize severe disease.Methods A scoping review was conducted in April 2025 following PRISMA-ScR guidelines. PubMed was searched for English-language articles from the last 25 years, alongside abstracts from major rheumatology conferences.

Objectives Several studies have reported weight gain with tumor necrosis factor inhibitors (TNFi) in psoriatic disease. However, such analyses have not accounted for the natural propensity for weight gain over time. We aimed to investigate whether therapy with TNFi in psoriatic arthritis (PsA) patients is associated with a change in the rate of weight gain post-treatment initiation.Methods We included patients with at least two weight measurements prior to, and after commencing TNFi and used cha

Background: Psoriasis is 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: We aimed to identify circulating metabolites associated with psoriasis, including cutaneous activity, severity, and psoriatic arthr

Background Psoriatic arthritis (PsA) and juvenile PsA (jPsA) are chronic inflammatory diseases with similar features that differ by age and sequence of symptom onset. PsA and psoriasis (PsO) share comparable pathology across ages, with interleukin (IL)-23 as a key mediator. Prior to the recent US FDA approval of guselkumab for treatment of pediatric plaque PsO and active jPsA, no approved pediatric treatment selectively targeted IL-23 signaling. Guselkumab (a fully human, dual-acting, IL-23p19 s

Objective To investigate the distribution characteristics of peripheral blood lymphocyte subsets in elderly psoriasis patients and analyze the interactions between immunosenescence and psoriasis and their impact on immune cell subpopulations.Methods This cross-sectional study enrolled 318 psoriasis patients and 167 healthy controls, stratified by age into elderly (≥ 65 years) and non-elderly (18-64 years) groups. Peripheral blood lymphocyte subsets, including CD3+ T cells, CD4+ T cells, CD8+ T c

Background: Managing psoriasis in patients with a history of lymphoma presents a unique clinical challenge. Psoriasis is associated with significant comorbidities such as cardiovascular disease and inflammatory arthritis, making optimal treatment vital. Systemic treatments like biologic agents may help mitigate these sequelae of systemic inflammation. However, concerns about immunosuppression in the context of lymphoma recurrence and progression complicate therapeutic decisions. Purpose: This re

In this commentary, we discuss the role of pharmacy benefit managers (PBMs) on access to biologics for patients with psoriasis. We highlight structural and system level barriers to biologics access, as well as how PBMs work as intermediaries between insurers, pharmacies, and drug manufactures to influence prescription formularies and generate health savings. We also discuss how controversial PBM practices such as step therapy, prior authorizations, and spread pricing may limit access to biologic

Diabetes and psoriasis are known to increase the risk of each other, yet their combined impact on long-term mortality remains unclear. This prospective cohort study examined the associations between the coexistence of diabetes and psoriasis and all-cause and cause-specific mortality in a nationally representative sample of U.S. adults. Data were obtained from 16,852 participants in the National Health and Nutrition Examination Surveys (NHANES). Survival was assessed using the Kaplan-Meier method

Once hailed as a breakthrough in psoriasis research, the imiquimod (IMQ) mouse model is now overused, inconsistently applied, and increasingly disconnected from human disease. Nearly a decade after our initial critique, the field remains reliant on a tool that models acute, innate inflammation rather than chronic, adaptive immunity. In this paper, we revisit the limitations of the IMQ model, highlighting methodological drift, poor transcriptomic overlap with psoriasis, and the illusion of mechan

Plaque psoriasis is a chronic skin disorder involving dysregulated inflammation. While numerous biologic therapies targeting inflammatory mediators have been approved for moderate-to-severe psoriasis, their safety profiles may include an increased risk of adverse events (AEs), such as infections, cardiovascular diseases, and malignancies. Because patients with psoriasis also have increased incidence of comorbidities, long-term real-world AE monitoring is critical to further evaluate the safety o

Background The pathogenesis of psoriasis is characterized by dysregulated post-translational modifications, with particular emphasis on fucosylation-a glycosylation process mediated by fucosyltransferases (FUTs). Keratin 17 (K17), overexpressed in psoriatic keratinocytes, drives inflammation and proliferation, but its interplay with fucosylation remains unclear. This study aimed to elucidate the role of fucosylation in psoriasis, specifically focusing on the regulation of K17 stability by FUT11.

Epidemiological association between psoriasis and T2DM suggests shared pathophysiology that are to be explored. Microarray expression profiles for psoriasis and T2DM were obtained from the Gene Expression Omnibus (GEO) database. The "limma" package in R software was used to screen the differentially expressed genes (DEG). GO and KEGG enrichment analysis were further conducted to explore the functions of co-DEGs. By intesecting genes of the key disease-related modules from WGCNA with co-DEGs, can

Many biologic therapies are available for moderate-to-severe plaque psoriasis. A systematic literature review and network meta-analysis (NMA) was conducted to compare the efficacy of the interleukin (IL)-23 inhibitor, tildrakizumab, with other biologics at up to 28 weeks of treatment. The literature search was conducted on January 22, 2024, searching MEDLINE, Embase, and CENTRAL for randomized controlled trials (RCTs) investigating the comparative efficacy and safety of biologics in adult Asian
