Psoriasis is a chronic inflammatory autoimmune skin disease with enhanced skin cell turnover. Despite the therapies currently available, better and target-oriented therapies are needed. Fisetin is a flavonoid with antioxidant, anti-inflammatory, and immunomodulatory properties. It shows therapeutic potential, but its poor bioavailability and penetration into the skin cannot be used effectively to treat psoriasis. While fisetin-loaded nanoformulations in cancer and other diseases have been explor

Psoriasis is a chronic, recurrent, inflammatory disease that is affected by genetic, immunological, epigenetic, and environmental factors. With the development of biotechnology, research on the pathogenesis of psoriasis has deeply focused on the field of epigenetics, and great progress has been made. Epigenetics is the study of heritable changes in gene expression or cell phenotypes without altering the DNA sequence. DNA methylation (DNAm) alterations are the most common epigenetic phenomena and

Psoriasis involving the genital region (GenPsO) is associated with impaired quality of life (QoL), including sexual burden and avoidance of sexual intercourse. There is limited data on the effectiveness of risankizumab in GenPsO on patients' QoL and sexual impairment. GPS-Best, a nested cohort non-interventional study within the German Psoriasis registry PsoBest, aims to evaluate the effectiveness of risankizumab in GenPsO and its impact on QoL and sexual impairment. This interim analysis involv

Once hailed as a breakthrough in psoriasis research, the imiquimod (IMQ) mouse model is now overused, inconsistently applied, and increasingly disconnected from human disease. Nearly a decade after our initial critique, the field remains reliant on a tool that models acute, innate inflammation rather than chronic, adaptive immunity. In this paper, we revisit the limitations of the IMQ model, highlighting methodological drift, poor transcriptomic overlap with psoriasis, and the illusion of mechan

Psoriasis is a chronic inflammatory skin disorder affecting 2-3% of the global population. It is increasingly recognized for its systemic comorbidities, especially cardiovascular diseases (CVDs). Notably, severe psoriasis independently increases cardiovascular disease (CVD) risk. This elevation occurs beyond conventional risk factors, such as hypertension and diabetes. It suggests that shared inflammatory pathways underlie the association between severe psoriasis and atherosclerotic conditions,

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

Numerous indicators have been proposed to evaluate the efficacy for randomized clinical trials (RCTs) of psoriasis (Pso) and psoriatic arthritis (PsA), but their comparability and correlation remain unknown. We aim to evaluate the preference and relative sensitivity of the most widely used indicators that report response rate, and to offer guidance for the primary endpoint selection for Pso and PsA trials. We conducted a systematic search, including five databases and four registries, to identif

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

Objective Residual confounding effects and disease severity are attributed to controversial results in studies of psoriatic disease (PsD) and mortality. We aimed to evaluate the risk of mortality in patients with incident PsD, compared to matched controls from the population.Methods We used the nationwide, population-based insurance claim datasets in Taiwan from 2010 to 2018. Incident cases of PsD were identified by International Classification of Diseases (ICD) codes. A nonexposed cohort was es

Previous research suggests that patients with hidradenitis suppurativa (HS) may face a higher risk of serious infections compared with those with psoriasis. However, these studies are subject to limitations that could constrain their reliability. To compare the risk of hospitalization from noncutaneous infections, infection profiles, and the length of stay (LOS) of adult patients with HS and psoriasis treated with adalimumab. This retrospective cohort study was conducted using deidentified claim

Psoriasis is a chronic inflammatory skin disease with a high world-wide incidence. Rutin, a natural citrus flavonoid glycoside, has been shown to have anti-inflammatory and antioxidant properties. To investigate the protective effects of rutin in imiquimod (IMQ)-induced psoriasis model mice and its underlying molecular mechanism. IMQ was applied to mice to induce inflammatory skin that phenotypically mimics psoriasis. The Psoriasis Area Severity Index (PASI) score was used to evaluate the degree

The Psoriasis Area and Severity Index (PASI) is widely used to evaluate psoriatic disease activity in clinical settings; however, its limitations hinder its practicality in routine use. The Simple-Measure for Assessing Psoriasis Severity (S-MAPA) has emerged as a promising tool addressing these limitations, providing a more feasible approach for assessing disease severity. This study aimed to evaluate the S-MAPA as a sensitive and practical alternative to existing instruments for measuring psori

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 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)

Aim Only limited data is available on the benefit of brodalumab 210 mg, an IL-17 receptor A antagonist, on patient-reported outcomes (PROs) in different psoriasis severity groups under real-world-evidence (RWE) conditions.Methods LIBERO, a prospective, multicenter, 12- and 52-weeks (W) non-interventional study on brodalumab in adult patients with plaque-type psoriasis assessed its short- and long-term impact on PROs in mild, moderate and severe psoriasis defined by Psoriasis Area Severity Index

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.
