Background Psoriasis is frequently associated with non-communicable disease (NCD) comorbidities, prompting interest in how these concurrent conditions may influence psoriasis treatment outcomes.Objectives To assess NCD prevalence and their influence on psoriasis treatment outcomes.Methods From 2022 to 2024, we recruited psoriasis patients in Shanghai Skin Disease Hospital. Data on demographic features, NCD comorbidities and treatment outcomes at week 4 and week 8 were systematically collected th

Psoriasis has been successfully treated by directly blocking the interleukin (IL)-23/IL-17 pathway and several inhibitors that specifically target the IL-23/IL-17 signaling axis have been approved by the Food and Drug Administration for clinical use and show excellent efficacy. However, all the approved IL-23/IL-17 axis targeting agents cannot be non-invasively delivered as topical treatment due to their biological and physicochemical properties, e.g., susceptibility to degradation, large molecu

Psoriasis is an immune-mediated chronic inflammatory disease. Increasing evidence suggests a close association between ribosome biogenesis (RiboSis) and the pathogenesis of psoriasis. However, the precise mechanisms remain unclear. We first obtained bulk transcriptome and single-cell RNA sequencing datasets from the GEO database. Subsequently, differential expression analysis (DEG) and weighted gene co-expression network analysis (WGCNA) were performed, preliminarily identifying 11 candidate bio

Abstract Objective To explore the clinical application value of Neutrophil extracellular traps (NETs) in evaluating psoriasis. Methods 2ml peripheral blood of 63 patients with psoriasis and 27 healthy controls were collected. Neutrophils were isolated by density gradient method, and the formation of NETs was observed by immunofluorescence staining. We then calculated the proportion and fluorescence intensity of NETs and analyzed their correlation with clinical classification, severity, and se

Objective To compare on-label persistence among adults with psoriasis who switched from other advanced therapies to guselkumab versus subcutaneous tumor necrosis factor inhibitors (SC TNFi), subcutaneous interleukin-17 inhibitors (SC IL-17i), or apremilast.Materials and methods This retrospective cohort study used U.S. claims data from the IQVIA PharMetrics® Plus database (2016- 2023). Overlap propensity score weights were used to balance cohorts on baseline characteristics. On-label persistence

Immune-mediated inflammatory diseases (IMIDs), such as psoriasis, psoriatic arthritis, and inflammatory bowel disease, encompass a heterogenous group of conditions associated with chronic inflammation. Systemic treatments for patients with IMIDs include parenterally delivered monoclonal antibodies (mAbs) that disrupt specific cytokine and cytokine receptor binding interactions, and orally delivered small molecules that inhibit certain enzymes involved in the regulation of inflammatory signaling.

Introduction The German national psoriasis registry PsoBest collects long-term data on the effectiveness, safety, and tolerability of systemic treatments for psoriatic disease. Here, we describe patient characteristics and the safety and effectiveness of apremilast for the treatment of psoriatic disease in Germany based on data from PsoBest.Methods This was a descriptive analysis of observational data collected from PsoBest using cross-sectional (baseline characteristics) and longitudinal (outco

Background Nail psoriasis (NP) is not an uncommon psoriasis variant whose symptoms have a negative impact on patients' quality of life. Treating NP can be a great challenge for the dermatologist, especially when it is presented as isolated subtype or when it is not associated with psoriatic arthritis (PsA). The available treatments, topical or systemic therapies, have limited efficacy and can be associated with adverse effects (AEs). Topical roflumilast is an FDA-approved treatment for skin plaq

Psoriasis is a complex inflammatory autoimmune skin illness that causes epidermal keratinocyte hyperproliferation and dedifferentiation. In a previous study we did in the lab, we found that treating human keratinocytes (HaCaT) with PUVA increased the expression of hsa-miR-718 compared to control. In this study, an imiquimod (IMQ)-induced mouse model and HaCaT were used to look at how overexpressing miR-718 could help treat psoriasis and its causes. To gain more understanding, the in vivo study u

Psoriasis is a significant global health challenge due to limited treatment efficacy. Paris saponin VII (PSVII) shows anti-inflammatory and anti-proliferative potential but its role in psoriasis is unclear. In this study, PSVII was identified from a library of natural compounds as a therapeutic candidate for psoriasis. In a murine model, PSVII reduced skin lesion severity, epidermal thickness, and inflammatory factor expression, preliminaryly indicating its anti-inflammatory properties. In vitro

Background Psoriatic disease (PsD) is a chronic, multisystem, inflammatory disorder encompassing psoriasis, psoriatic arthritis (PsA), and their associated comorbidities.Objective The aim of this subanalysis of the global "Psoriasis and Beyond" study was to evaluate patients' experiences of living with PsD in the USA.Methods The study included a cross-sectional, quantitative, 25-min online survey of adults with self-reported, healthcare professional-diagnosed, moderate-to-severe psoriasis, with

Introduction Psoriasis body surface area (BSA) of 10% or more has been a major criterion for determining systemic therapy eligibility. However, patients with BSA < 10% and even ≤ 3% may have high disease burden and difficulties accessing biologics. To assess psoriasis burden among patients with BSA ≤ 10%, this study characterized patient-reported outcomes (PROs) across BSA categories among systemic treatment-naïve patients initiating biologic therapy.Methods Patients from the CorEvitas Psoria

Objective Psoriatic arthritis (PsA) is a chronic inflammatory condition associated with psoriasis and characterised by heterogeneous clinical manifestations, including peripheral and axial arthritis, enthesitis and dactylitis. A subset of patients exhibits a 'difficult-to-treat' (D2T) phenotype, necessitating complex therapeutic strategies. Metabolic syndrome (MetS) is highly prevalent in PsA patients and has been implicated in increased disease activity.This study aimed to evaluate the impact o

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

Adalimumab, a tumor necrosis factor-alpha inhibitor, is widely used for chronic plaque psoriasis and psoriatic arthritis. While cutaneous adverse effects are known, perforating dermatosis is rare and poorly understood. A 34-year-old woman with psoriasis and psoriatic arthritis developed acquired perforating dermatosis after switching from adalimumab biosimilar GP2017-CTP17. She presented painful, ulcerated plaques on the thighs, gluteal area, and elbows. Histopathology confirmed the diagnosis. T

Introduction Interleukin-17 inhibitors (IL-17i) and interleukin-23 inhibitors (IL-23i) are advanced therapeutic options for moderate-to-severe psoriasis. In real-world settings, biologic persistence is commonly used as a proxy for effectiveness and safety, and a treatment-free status following biologic discontinuation may provide insights into disease remission. This study aimed to assess persistence and treatment-free status for IL-17i versus IL-23i among biologic-naïve patients with psoriasis

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

Aim Risankizumab is a high-cost biologic treatment for chronic plaque psoriasis, an immune-mediated inflammatory disease presenting with painful red scaly skin lesions. Inter-individual heterogeneity in treatment response may be better addressed with personalised rather than fixed dosing. We sought to develop a pharmacokinetic/pharmacodynamic (PK/PD) model to characterise the relationship between risankizumab exposure and treatment response.Methods A sequential population PK/PD model was develop

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

Introduction Targeted biologic therapies have transformed outcomes for individuals with psoriasis, a common immune-mediated inflammatory skin disease. The widespread use of these highly effective treatments has led to a growing number of individuals with clear or nearly clear skin remaining on continuous, long-term treatment. Personalised strategies to minimise drug exposure may sustain long-term disease control while reducing treatment burden, associated risks and healthcare costs. This study a

The underlying mechanisms of atherosclerosis and strategies for identifying high cardiovascular risk in psoriasis are incompletely understood. Platelet activity is increased in psoriasis and induces vascular dysfunction. We investigated the platelet phenotype and platelet transcriptome as one potential mechanism to explain cardiovascular risk in psoriasis. Psoriasis and controls underwent platelet aggregation and activation studies and platelet RNA sequencing to generate a psoriasis platelet tra
