Background/Objectives: Psoriasis is a chronic inflammatory skin disease increasingly linked to psychiatric and behavioral comorbidities, including depression, anxiety, and substance use disorders. Shared inflammatory pathways, including elevated IL-6, TNF-α, and IL-17, may link psoriasis with psychiatric disorders such as depression and anxiety. The bidirectional interaction between systemic inflammation and mental health may exacerbate the disease burden and affect treatment outcomes. The objec

Introduction Nail psoriasis is a common, treatment-refractory manifestation of psoriasis. Smoking is a key environmental factor implicated in nail and articular psoriasis. While smoking's association with cutaneous psoriasis is well-studied, its relationship with nail psoriasis remains less explored.Objective The primary objective of this study was to investigate the impact of smoking on the severity of nail psoriasis and arthritic psoriasis in patients with nail psoriasis.Methods Data from 1044

Psoriasis is a chronic inflammatory skin disease that forms a vicious cycle with psychological stress. Whether and how the hypothalamic-pituitary (HP) axis-mediated neuroendocrine system regulates psoriasis remains obscure. Here, we report elevated levels of the pituitary hormone prolactin (PRL) in both psoriasis patients and imiquimod (IMQ)-induced psoriasis mice. Mechanistically, PRL acts on dermal PRLR-expressing fibroblasts to promote the production of the chemokines CCL2 and CCL7, which the

Background Psoriasis is a chronic, immune-mediated inflammatory dermatosis associated with an elevated risk of cardiovascular disease (CVD) due to systemic inflammation and metabolic dysregulation. Phenotypic age acceleration (PhenoAge-accel) quantifies accelerated biological aging by comparing an individual's predicted 'phenotypic age' (based on immune/inflammatory markers and chronological age) to their actual age. Notably, both the onset and progression of psoriasis exhibit strong association

Background Psoriasis is a chronic inflammatory skin disease, and the risk of developing cancer has been postulated due to the presence of several plausible underlying mechanisms. Understanding the association between psoriasis and cancer is imperative to the provision of optimal psoriasis care.Objectives To examine the risk of developing cancer in individuals with psoriasis.Methods Population-based cohort studies were conducted in Denmark, England, Israel, and Taiwan through the use of linked el

Psoriasis is a chronic immune-mediated skin disease that is increasingly understood as a systemic inflammatory condition with implications that extend far beyond the skin. Among its most serious associations is an elevated risk of cardiovascular disease, which has emerged as a leading cause of morbidity and mortality in affected patients. The persistent immune activation characteristic of psoriasis, driven by cytokines such as tumor necrosis factor α (TNFα), interleukin (IL)-17, and IL-23, contr

Psoriasis, long thought to be a chronic immune-mediated dermatological disease, is now being reclassified as a systemic inflammatory disease with substantial metabolic and hepatic complications. Psoriasis affects approximately 2-3% of global population and is associated with up to 50% risk of systemic comorbidities. This mini-review examines the evolving understanding of psoriasis pathogenesis, focusing on the interaction of immunological dysregulation, keratinocyte hyperproliferation, and syste

Purpose This study aimed to investigate the risk of anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAVs) among patients with psoriasis in a large population.Patients and methods In this population-based study using the collaborative electronic health record research network, the risk of developing AAVs (ie, eosinophilic granulomatosis with polyangiitis (EGPA), granulomatosis with polyangiitis (GPA), and microscopic polyangiitis (MPA)) was analyzed in a cohort of patients diag

Background: Psoriasis is a chronic autoimmune condition characterized by recurrent episodes of skin inflammation. Despite progress in treatment, managing flare-ups of psoriasis remains a significant hurdle once the therapy is halted. This review aims to unravel the enigma of relapse by examining the interactions between epigenetics, metabolic reprogramming, and inflammatory memory.Methods and Results: Skin-resident memory T cells and keratinocytes with a history of inflammation play crucial role

Objective This study evaluated psoriasis treatment teaching in dermatology residency programs across Latin America (LATAM).Methods A Spanish/Portuguese survey was distributed to directors of dermatology departments/training programs and their residents in several LATAM countries between November 29, 2022, and March 31, 2023.Results A total of 108 individuals responded (59 directors and 49 residents) from eight countries: Argentina (2.8%), Brazil (41.7%), Chile (25.0%), Colombia (7.4%), Guatemala

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 autoimmune disease of the skin manifested by keratinocyte hyperproliferation, immune dysregulation, and chronic inflammation that result in scaly plaques. Conventional interventions such as corticosteroids, immunosuppressants, and biologics offer symptomatic relief but are limited by side effects and incomplete remission. Psoriasis pathogenesis is complex and entails numerous immune cells (dendritic cells, Th1, Th17, Th22, Tregs, macrophages, NK cells) and molecular pathwa

Psoriasis is a chronic inflammatory skin disease affecting millions of people worldwide. Although growing evidence links chronic inflammation with increased cancer risk, the association between psoriasis and cutaneous squamous cell carcinoma (cSCC) is still elusive. Using cell transplantation and chemical-induced models of cSCC combined with inducible genetically engineered mouse models of psoriasis, we investigated how chronic skin and systemic inflammation affects squamous skin tumor initiatio

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

Objectives Little is known about the ideal service delivery model and shortcomings in patient experiences in the NHS for patients with psoriatic arthritis (PsA). The objective of this work was to identify unmet needs perceived within the current health service delivery model for PsA from the UK Psoriatic Arthritis Priority Setting Partnership (PsA-PSP).Methods An online survey was conducted in 2020 and distributed to people with PsA, their carers and clinicians to identify research priorities in

Objectives Biologic therapies for skin psoriasis (PsO) have been linked to a lower risk of developing psoriatic arthritis (PsA), but their efficacy across different mechanisms of action remains to be fully explored. This study aimed to compare PsA risk in PsO patients prescribed interleukin-23 inhibitors (IL23i) vs interleukin-17 inhibitors (IL17i).Methods This retrospective cohort study utilized the TriNetX database to categorize adult PsO patients into two cohorts: those newly prescribed IL23i

The psoriatic arthritis phenotype has evolved over the past several decades. The original description of 5 clinical patterns has been expanded into 6 domains including peripheral arthritis (which includes 3 of the patterns described by Moll and Wright namely distal, oligoarticular and polyarticular), axial disease, dactylitis, enthesitis, skin and nails. In this article we review the evolution of the PsA phenotype, from the Moll and Wright subtypes described in 1973 and how they might have chang

Psoriatic arthritis (PsA) is a chronic, immune-mediated inflammatory arthritis associated with psoriasis, affecting joints, entheses, and the axial skeleton. While primary care providers and dermatologists frequently encounter psoriasis (PsO), early recognition of PsA remains critical to preventing irreversible joint damage. This paper is written to provide a comprehensive overview of PsA, beginning with a clinical case that highlights diagnostic and therapeutic challenges. In this review, the e
