Psoriasis is a chronic inflammatory skin disease driven by immune dysregulation. This study explores the role of B cells, particularly cytokine-producing subsets, in psoriasis pathogenesis. Although T cells, particularly Th17, have been well documented in psoriasis, recent evidence suggests that B cells contribute to the disease process. Flow cytometry analysis of 50 psoriasis patients and 20 healthy controls revealed a significant increase in IL-6-producing effector B cells (Beffs) and a decrea

Introduction Research findings show a substantial correlation between Crohn's disease and psoriasis. However, the exact cause or pathogenesis of the concurrent manifestations of these two conditions in the same individuals remains uncertain. This research aimed to scrutinize the important molecules and mechanisms responsible for the concomitance of Crohn's disease and Psoriasis by using quantitative bioinformatics utilizing a publicly available RNA sequencing repository.Methods The database Gene

The aim of this study was to translate and culturally validate the Psoriatic Arthritis Quality of Life Questionnaire (PsAQoL) into Turkish and to evaluate its reliability and validity in patients with psoriatic arthritis (PsA). A total of 162 PsA patients diagnosed according to CASPAR criteria were recruited from two rheumatology clinics. The PsAQoL was translated and culturally adapted into Turkish using a standardized forward-backward translation method. Internal consistency was assessed using

Introduction Psoriasis is a chronic, systemic inflammatory disease with significant physical and psychosocial burden. Advances in understanding the pathogenesis of psoriasis, particularly the role of interleukin (IL)23/Th17 axis, have led to the development of selective drugs targeting these cytokines. Among these, IL23 inhibitors (guselkumab, risankizumab, and tildrakizumab), represent the most recent class of biologic drugs approved for the management of moderate-to-severe plaque psoriasis. Si

Background Psoriasis is frequently associated with metabolic syndrome and an increased cardiovascular risk. Tildrakizumab, an IL-23 inhibitor, may affect metabolic parameters in addition to improving skin severity.Aim of the study To evaluate the impact of increasing tildrakizumab dosage on lipid and glucose levels in psoriasis patients with metabolic syndrome who showed a partial response to the standard 100 mg dose.Materials and methods Twenty-five patients with psoriasis and metabolic syndrom

Background Although IL-17 inhibitors like Secukinumab and Ixekizumab have shown significant efficacy in psoriasis, the impact of early intervention with biologics to modify the disease course and achieve long-term remission remains unclear.Objectives To examine the potential of early intervention with IL-17 inhibitors for disease modification in psoriasis.Methods We conducted a multicenter retrospective cohort study on moderate-to-severe plaque psoriasis patients who received at least 4 weeks of

Psoriasis is a chronic autoimmune disease of the skin manifested by keratinocyte hyperproliferation, immune dysregulation, and chronic inflammation that result in scaly plaques. Conventional interventions such as corticosteroids, immunosuppressants, and biologics offer symptomatic relief but are limited by side effects and incomplete remission. Psoriasis pathogenesis is complex and entails numerous immune cells (dendritic cells, Th1, Th17, Th22, Tregs, macrophages, NK cells) and molecular pathwa

Psoriasis, the most common inflammatory skin disease, is marked by excessive proliferation of keratinocytes and infiltration of immune cells into the epidermis. Current treatments, particularly biologics targeting the IL‑23/IL‑17 axis, demonstrate excellent efficacy, but issues of recurrence and side effects persist. Therefore, it is essential to identify safer and more effective alternatives. Lobetyolin (LBT), a key component of polyacetylenes in Codonopsis pilosula, exhibits potent antioxidant

Psoriasis is a chronic, multifactorial, inflammatory skin disease, increasingly recognized as a systemic disorder influenced by the gut-skin axis, which is a dynamic bidirectional communication between intestinal microbiome and cutaneous immune response. This narrative review explores the understanding of the gut-skin axis with the latest evidence on how gut dysbiosis occurs in psoriasis, characterized by reduced microbial diversity and its shifts, and how it contributes to pathogenesis and exac

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.

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

Background Psoriasis is a chronic inflammatory disease associated with abnormalities in the immune system. Microsomal prostaglandin E synthase-1 (mPGES-1), a terminal enzyme for prostaglandin (PG) E2 biosynthesis, is highly expressed in the skin of psoriasis patients. However, the detailed role of mPGES-1 in psoriasis remains unclear. In the present study, we aimed to investigate the role of mPGES-1 in psoriasis-like skin inflammation induced by imiquimod (IMQ), a well-established model of psori

Patients with autoimmune diseases are susceptible to developing a second autoimmune disorder. Psoriasis, a common autoimmune disease, frequently occurs alongside other autoimmune conditions in some individuals. We report the case of a young female patient diagnosed with plaque psoriasis, initially treated with secukinumab, and achieved complete skin clearance at 12 weeks. However, she experienced a decline in the efficacy of secukinumab, with recurrence of symptoms and subsequent development of

Background Patients' quality of life is greatly impacted by psoriasis, a prevalent chronic inflammatory skin condition that is frequently linked to a number of systemic disorders. Recent research shows that obesity is a major risk factor for psoriasis. Since Relative Fat Mass (RFM), an innovative way to measure obesity, offers a more precise estimate of body fat percentage, this study aims to investigate the connection between RFM and psoriasis and its potential as a disease predictor.Methods Th
