Background/purpose While biologics and small-molecule inhibitors are first-line systemic treatments for psoriasis, phototherapy remains an alternative for patients unable to access these treatments because of medical or financial constraints. Narrow-band ultraviolet B (NB-UVB) is effective for localized psoriasis but less so for extensive disease. To address this limitation, bathwater delivery of psoralen plus ultraviolet A (bath-PUVA) was introduced in 2004. This study evaluates the efficacy, s

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

Background Genetic susceptibility to psoriasis involves multiple loci, including TYK2 (Tyrosine Kinase 2), which is associated with various autoimmune diseases. However, its specific role and mechanisms in psoriasis remain unclear. This study aimed to identify psoriasis-associated proteins using Summary-based Mendelian Randomization (SMR) and to explore their regulatory mechanisms.Methods SMR analysis integrating pQTL data was conducted to identify proteins linked to psoriasis, revealing ICAM1 (

Psoriasis and psoriatic arthritis are chronic autoimmune diseases characterized by dysregulated immune responses, particularly involving Th17 cells. Immune checkpoint molecules such as programmed death-1 (PD-1) and its ligands (PD-L1/PD-L2) are critical for maintaining immune tolerance. Disruptions in these pathways contribute to psoriatic disease pathogenesis. Notably, immune checkpoint inhibitors used in cancer therapy have been linked to the development of psoriasis or its exacerbation. This

Objectives Through this meta-analysis, we aim to provide an overview and statistical synthesis of the prevalence of MetS and its components in psoriatic arthritis (PsA) compared to the general populations, patients with cutaneous psoriasis (PsO), and patients with other inflammatory arthropathies.Method A search was conducted in Ovid Medline, Web of Science, and Scopus up to February 2024. Original articles investigating the prevalence of MetS in PsA in adults compared to one or more comparison

Abstract Psoriasis is a chronic skin condition characterized by the rapid growth of skin cells, leading to the formation of thick, scaly patches. Detecting these lesions accurately is crucial for early diagnosis and effective treatment. However, the variability in lesion size, shape, and appearance across different skin types presents significant challenges for automated detection systems. Traditional methods often struggle with these variations, leading to reduced accuracy and efficiency. In r

Psoriasis, a chronic autoimmune skin disease, arises from both genetic predisposition and environmental factors, including Adverse Childhood Experiences (ACEs). This cross-sectional study investigated the association between ACEs, family history, and early-onset psoriasis (≤ 18 years), with particular attention to gender differences. Among 102 psoriasis patients (54 early-onset, 48 late-onset), the early-onset group demonstrated a higher proportion of females, greater prevalence of parental psor

Unlabelled This study analyzed over 2000 images of psoriasis across major web-based platforms and found a significant underrepresentation of darker skin tones, highlighting a critical gap in dermatologic representation that may contribute to misdiagnoses and health disparities among patients with skin of color.Weiterlesen

The Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA)-Outcome Measures in Rheumatology (OMERACT) psoriatic arthritis (PsA) working group provided updates at the GRAPPA 2024 annual meeting on their assessment of composite outcome measures for PsA. The group presented the progress of a systematic literature review on the psychometric properties of the following candidate composite outcome measures using the OMERACT filter 2.2: (1) minimal disease activity (MDA), (2) D

Background: Psoriasis is a chronic inflammatory disease associated with high morbidity and few cases of sustained remission. Innovative immunomodulatory therapies, including fibroblast-based cell therapies, offer promising alternatives. This study investigates the therapeutic potential of human dermal fibroblasts (HDFs) organized into three-dimensional (3D) spheroids in a mouse model of imiquimod (IMQ)-induced psoriasis. Methods HDF spheroids were cultured using Elplasia microcavity plates, an

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

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

Objective This study aims to investigate the relationship between Relative Fat Mass (RFM) and the risk of psoriasis based on data from the US National Health and Nutrition Examination Survey (NHANES) from 2009 to 2014.Methods This cross-sectional study included 19,565 adults aged 20 years and older. Psoriasis diagnosis was determined using self-reported questionnaires, and RFM was calculated based on established formulas. Multivariable logistic regression models were used to analyze the associat

Objectives Psoriatic arthritis (PsA) is a heterogeneous inflammatory disease in which a significant proportion of patients remain refractory to existing therapies. The Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA) initiated a project aimed at unravelling the reasons for treatment failures in PsA, culminating in the establishment of definitions for difficult-to-treat PsA (D2T-PsA) and complex-to-manage PsA (C2M-PsA). This study explores patient perspectives on tr

At the Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA) 2024 annual meeting, Drs. Dennis McGonagle and Wilson Liao discussed "MHC-I-opathies," a class of immune-mediated diseases genetically associated with major histocompatibility complex class I (MHC-I) and class I peptide processing. MHC-I-opathies demonstrate epistatic interactions, genetic associations, and immunopathology that are distinct from classic B cell and autoantibody-driven autoimmune diseases. Inves

Guttate psoriasis (GP) is a variant of psoriasis. Approximately 2-4% of the world population is affected by psoriasis; of this, about 30% will be diagnosed with guttate psoriasis. GP primarily affects children and young adults. Like other psoriasis, guttate psoriasis is an immune-mediated dermatological disorder. GP is distinct, given it is classically an acute rash following a streptococcal infection.Weiterlesen

Psoriasis is a chronic immune-mediated disease mainly affecting the skin with different clinical manifestations. As patients with psoriasis may also suffer from psoriatic arthritis and the skin lesions of psoriasis are disfiguring, their quality of life is often impaired. Many environmental and genetic factors have been implicated in psoriasis development. Currently, there is no cure for the disease and long-term drug treatment is usually necessary, especially in moderate to severe cases. Mesenc

Psoriasis is an immune-mediated skin disease manifested in more than 3% of Americans and over 125 million people worldwide. The inflammatory skin condition with an increased rate of keratinocyte turnover involves every level of the skin and exhibits various forms of the disease, including plaque, guttate, inverse, pustular, and erythrodermic psoriasis, as well as disease-associated conditions, such as psoriatic arthritis and nail psoriasis. Innovative treatment has highlighted the importance of
