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 features keratinocyte hyperproliferation. This study aimed to identify disulfidptosis-related key genes in psoriasis for potential diagnostic biomarkers or therapeutic targets. Using the GSE30999 dataset, WGCNA was applied to identify key gene modules. GO, KEGG were used for analysis. IHC, Western blot, PCR and free thiol tests verified results. WGCNA clustered differentially expressed genes into 18 modules, with the blue module being significantly associated with psoriasis (Pearson's

Background General Practitioners (GPs) act as primary gatekeepers for patients with psoriasis and their screening practice for cardiovascular disease (CVD) and psoriastic arhtiris (PsA) y. This study aimed to assess the awareness and screening routines of Danish GPs regarding CVD and PsA in patients with psoriasis.Methods A nationwide cross-sectional survey on screening practice was conducted involving 490 randomly selected Danish GPs. Data were analyzed descriptively based on 101 responses (21%

Background Data on the prevalence of sensitive skin in patients with chronic inflammatory skin diseases are lacking. The aim of this study was to address this gap.Methods This observational study included patients with psoriasis, atopic dermatitis or chronic hand eczema who attended the Unit of Dermatology of Ferrara and Messina, Italy, between June and December 2023. All participants completed a 10-item questionnaire for the diagnosis of sensitive skin (score range: 0-10). Participants were cla

Background While clinical examination remains the diagnostic cornerstone for psoriasis, there is a relative lack of objective, quantitative biomarkers to complement clinical assessment for tracking disease severity and monitoring therapeutic response. We evaluated serum SCCA's utility in identifying psoriasis and assessing its severity across demographic (gender, age) and clinical (comorbidity) subgroups, and its association with therapeutic responses.Methods A total of 181 adult (≥18 years old)

Objective The purpose of this study was to evaluate the relationship between nutritional status-assessed by the Controlling Nutritional Status (CONUT) score-and disease activity, fatigue, and sleep quality in patients with psoriatic arthritis (PsA), with attention to sex-specific differences.Methods 113 adults with PsA were included in this cross-sectional study. Nutritional status was classified as normal (CONUT 0-1) or malnutrition (CONUT ≥ 2). Disease activity was assessed using the Disease A

Psoriasis, a chronic skin autoimmune disease characterized by abnormal immune responses, is influenced by genetic and environmental factors. Recent microbiota research has revealed that short-chain fatty acids (SCFAs), metabolites produced by gut microbiota, play a pivotal role in regulating immune function and inflammation. This review examines the current literature on the relationship between gut dysbiosis, SCFA production, and immune modulation in psoriasis, focusing on emerging evidence fro

Psoriasis is a chronic, complex immune-mediated inflammatory disorder with cutaneous and systemic manifestations in which keratinocytes, dendritic cells and T cells have central roles. UBE2L3 may be a protective biomarker that regulates the pathogenesis of psoriasis. Here, we identify the IL-17A signaling similarity between human psoriatic skin and Ube2l3 conditional knockout mouse skin in the epidermis rather than dermis. IL-17A is regulated by CXCR6+ Vγ2+ γδT cells in mouse while CXCR6+ CD8+ T

Background Psoriasis is a chronic, immune-mediated, inflammatory skin disease characterized by abnormal keratinocyte proliferation, in which M1 macrophage polarization plays a critical role. However, the specific biomarkers and mechanisms underlying macrophage polarization in psoriasis remain unclear.Methods We analyzed the psoriasis dataset (GSE14905) to identify differentially expressed genes and applied weighted gene co-expression network analysis to identify key module genes. Macrophage pola

Skin infiltration by neutrophils is a hallmark of the chronic inflammatory skin disease psoriasis, yet the mechanisms underlying neutrophil recruitment and positioning in chronically inflamed skin remain poorly understood. In this study, we demonstrate the significant impact of a total genetic deficiency of secretory leukocyte protease inhibitor (SLPI) on neutrophil migration in mouse skin. Without SLPI, neutrophils displayed an unconventional migratory pattern, characterized by altered interact

Psoriasis is an incurable and recurrent skin disease, and the need to develop new strategies for the treatment of psoriasis persists. Smilax glabra Roxb. (SGR) is listed as a key traditional Chinese medicine for the treatment of psoriasis through medicinal bath therapy in "Guideline for the diagnosis and treatment of psoriasis in China"; the active ingredients responsible for its anti-psoriatic effects and their mechanisms of action still require in-depth research. In this study, we first found

Objective To quantify sociodemographic differences in the prevalence of diagnosed psoriasis and to evaluate temporal trends in its epidemiologic distribution.Methods Data from the 2003-2006 and 2009-2014 National Health and Nutrition Examination Survey and the 2023-2024 National Health Interview Survey were analyzed. Meta-analysis was performed to determine whether age, sex, race/ethnicity, interview language, marital status, BMI, education, income, and health insurance are independently associa

Background Psoriasis is an immune-mediated chronic inflammatory condition characterized by significant neutrophil infiltration in the skin. Given that the spleen is the largest peripheral immune organ in the body, it is important to investigate whether it has any impact on skin inflammation in psoriasis.Methods To investigate this mechanism, a psoriatic mouse model was established by IMQ application. Flow cytometry and immunohistochemistry analyses were performed to determine the percentage of v

Sternoclavicular joint (SCJ) involvement in psoriatic arthritis (PsA) is poorly characterized. We aimed to assess its prevalence and clinical associations in a longitudinal PsA cohort. We retrospectively analyzed prospectively collected data from the Gladman Krembil Psoriatic Arthritis Program. Patients with SCJ involvement (tender and/or swollen SCJ) were identified, and their demographic, clinical, laboratory, and treatment details were retrieved. Univariable and multivariable generalized esti

Psoriasis is a chronic systemic inflammatory skin disorder that is strongly associated with metabolic disorders, including obesity, insulin resistance, hypertension, and dyslipidemia. Dyslipidemia causes abnormalities in lipid profiles, such as elevated triglycerides or low density lipoprotein (LDL) levels. Measure maternally expressed gene 3 (MEG3) and microRNA-147b in serum of patients with and without dyslipidemia compared to healthy control. These measurements were compared with clinical cha

Psoriatic arthritis (PsA) develops in up to one-third of patients with psoriasis (PsC), yet increasing attention is now focused on a putative subclinical phase preceding overt arthritis. Several conceptual frameworks describe the PsC-PsA transition, including the pragmatic definition proposed by the European Alliance of Associations for Rheumatology, which defines subclinical PsA as arthralgia and/or imaging abnormalities in the absence of clinical synovitis. However, the absence of validated se

Prolonged glucocorticoid therapy may lead to adrenal insufficiency (AI) or even adrenal crisis (AC) due to suppression of the hypothalamic-pituitary-adrenal (HPA) axis. This case report describes a male patient with psoriasis who had received long-term irregular glucocorticoid therapy for psoriasis management. Following an upper respiratory tract infection, the patient developed generalized skin lesions accompanied by systemic symptoms including abdominal pain, vomiting, fatigue, fever, and leth
