Psoriasis is a common chronic inflammatory skin disease that significantly affects patients'quality of life. There is no cure for psoriasis, and available treatments are not completely effective. We have previously found that hydroxytyrosol (HT) has anti-psoriatic effects in vitro. In the present study, we aimed to investigate the therapeutic effects of HT on psoriasis in vivo and to explore the underlying mechanisms. We explored the effects and molecular mechanisms of HT on imiquimod (IMQ)-indu

Purpose Secukinumab, an interleukin-17 A (IL-17 A) inhibitor, is an approved treatment for psoriasis, but effects on the hypothalamic pituitary adrenal (HPA) axis are unknown.Methods In a 16-week randomized controlled trial, 105 patients with psoriasis received secukinumab at either 300 or 75 mg. Plasma levels of IL-17 A, cortisol, adrenocorticotropic hormone, prolactin, dehydroepiandrosterone and perceived stress using Perceived Stress Scale (PSS-10) were measured at baseline and every four wee

Background Psoriasis has been associated with an increased risk of various cancers, including thyroid cancer (TC), yet the molecular mechanisms linking these two diseases remain unclear.Objective This study aimed to identify and analyze the differentially expressed genes (DEGs) between TC and psoriasis using bioinformatics approaches to explore potential molecular mechanisms and shared pathways. To the best of our knowledge, this is the first bioinformatics-based study to systematically identify

Objective Psoriatic arthritis (PsA) is a chronic immune-mediated inflammatory arthritis that develops in 30% of patients with psoriasis, leading to increased morbidity and mortality and reduced quality of life. MicroRNAs (miRNAs) modulate gene expression and have been associated with the pathogenesis of immune-mediated disorders. We aimed to identify miRNAs that can be used as biomarkers for the development of PsA in patients with psoriasis.Methods miRNA expression levels were assessed in serum

Background Psoriasis is an inflammatory disorder characterized by scaly erythematous plaques and significant comorbidities. Recent studies have suggested that impaired mitophagy, the cellular mechanism for removing dysfunctional mitochondria, may contribute to the pathogenesis of psoriasis.Methods In this study, we analyzed bulk RNA sequencing data from 167 healthy individuals and 177 patients with psoriasis obtained from the Gene Expression Omnibus database (GSE30999 and GSE54456). Mitophagy-re

Psoriasis is an inflammatory skin disease, and current treatments have their own limitations, including moderate treatment effectiveness, poor compliance, and potential safety risks, etc. Therefore, the primary focus of this study is to explore novel molecular targets and improve the diagnosis and treatment of psoriasis patients. In this study, comprehensive bioinformatics analysis was performed on the expression profiles of tissue samples from patients with psoriasis in the clinical trial of TY

Background Psoriasis is an immune-mediated skin disease where Th17 cell differentiation and IL-17 secretion play critical roles. This study investigates key exosomal ncRNAs regulating the Th17/IL-17 axis in psoriasis and their mechanisms.Methods We integrated bulk RNA sequencing datasets from the GEO database to construct and evaluate exosome-related patterns. Subsequently, exosome-related ncRNAs in psoriasis lesions were identified primarily through weighted gene co-expression network analysis

Anoikis is a programmed cell death that occurs when cells detach from the extracellular matrix (ECM). Its role in psoriasis remains unclear. This study aims to explore the relationship between psoriasis and apoptosis, focusing on anoikis-related mechanisms. Differentially expressed genes (DEGs) in psoriasis were identified using the GEO database and overlapped with anoikis-related genes from GeneCards to find differentially expressed anoikis-related genes (DE-ARGs). A PPI network was constructed

Background Psoriatic arthritis (PsA) is an immune-mediated chronic inflammatory disease that causes chronic pain, psychological problems, and a significant economic burden, and therefore must be diagnosed and treated early. Existing treatments have limited efficacy and side effects. The study aimed to identify potential drug targets associated with psoriatic arthritis through proteomics and Mendelian randomization (MR) analysis.Materials and methods Large-scale genome-wide association studies an

Objectives This study aimed to evaluate the required test characteristics that a psoriatic arthritis (PsA) biomarker test would need to achieve to be considered cost-effective.Methods We adapted an existing Markov model to compare a hypothetical biomarker with current practice. The model followed a patient cohort aged 45 years with moderate psoriasis (PsO) in which PsA was prevalent but unrecognized over a 40-year time horizon. Patients were assumed to be routinely seen at a dermatology clinic.

Abstract 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 a latent class analysis on 17 dichotomous ASAS HI items in a cohort of patients with PsA (n: 90). A Gaussian mixture model was applied, and the optimal number of classes was selected based on the Akaike (AIC) and

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

Introduction Psoriatic arthritis (PsA) is an immune-inflammatory disease involving skin and synovial-entheseal compartments. The understanding of IL-17 biological function has revolutionized the understanding of PsA pathogenesis and, consequently, its therapeutic approach.Areas covered In this review article, we have outlined the primary evidence regarding the biological functions of IL-17A in PsA, and summarized data from randomized controlled trials (RCTs) on PsA and psoriasis approved secukin

Background The IL-17A inhibitors target aberrant immune responses in psoriasis but also impacts the host's defense against infections. The effects of this treatment on skin microorganisms and microbiome-encoded metabolic pathways remain unclear.Objectives This was an exploratory clinical study designed to investigate whether Psoriasis is associated with skin microbiota, as well as a longitudinal cohort study aimed at revealing the effects of IL-17A inhibitor treatment on skin microbiota in Psori

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

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

Psoriasis is a prevalent inflammatory skin disorder with immune-related mechanisms that remain incompletely understood. To elucidate the immune landscape of psoriasis, we analyzed expression profiles to identify 115 psoriasis susceptibility genes (PSGs) and subsequently pinpointing eight immune-related hub genes (IRHGs). A predictive model incorporating these IRHGs demonstrated promising prognostic potential for psoriasis. Additionally, extensive intercellular communication was observed among ke

Unregulated herbal supplements can pose significant health risks due to undisclosed ingredients. Tawon Liar, an Indonesian product marketed as an "all-natural" remedy, claims to alleviate pain and boost immunity but lacks stringent regulatory oversight. We report a unique case of Tawon Liar-induced Immunoglobulin A (IgA) vasculitis and exacerbation of psoriasis, highlighting the potential dangers associated with misadvertised supplements. A 53-year-old migrant worker from Mexico with a history o

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

Background and objectives Psoriasis can result in reduced quality of life, work productivity loss, and a significant restriction in non-professional activities. This study investigates the effects of long-term treatment with adalimumab regarding work ability, non-professional activities, and health-related quality of life in a large real-word population in Germany.Patients and methods Single-arm, multicenter non-interventional study to document routine care data for up to 5 years in adult patien

Background Pediatric psoriasis is a chronic inflammatory skin disease that affects both physical and psychosocial well-being. The impact of the disease extends beyond the patient, significantly affecting caregivers' emotional and functional quality of life.Objectives This systematic review and meta-analysis aimed to evaluate the health-related quality of life (HrQOL) burden of pediatric psoriasis on children and their caregivers. The study also sought to identify clinical and child-related facto

Psoriasis is an autoimmune inflammatory condition that often intersects with orthopaedic care due to its connection to psoriatic arthritis. However, not all psoriasis patients develop psoriatic arthritis. Psoriasis patients may undergo hip or knee arthroplasties for reasons unrelated to psoriasis. This condition, marked by inflamed, scaly skin caused by an overactive immune system, may pose challenges for orthopaedic surgeries. This systematic review evaluated outcomes for psoriasis patients aft
