Ixekizumab is a monoclonal antibody used in the treatment of moderate-to-severe psoriasis and psoriatic arthritis by targeting interleukin-17 A (IL-17 A). It has demonstrated efficacy in controlling inflammation in autoimmune diseases, though adverse reactions can arise. This case study reports a case of 25-year-old female with psoriatic arthritis undergoing treatment with ixekizumab, who developed acute enlargement and inflammation of a pre-existing sebaceous cyst located posterior to the left

Background The pathogenesis of psoriasis is characterized by dysregulated post-translational modifications, with particular emphasis on fucosylation-a glycosylation process mediated by fucosyltransferases (FUTs). Keratin 17 (K17), overexpressed in psoriatic keratinocytes, drives inflammation and proliferation, but its interplay with fucosylation remains unclear. This study aimed to elucidate the role of fucosylation in psoriasis, specifically focusing on the regulation of K17 stability by FUT11.

Psoriasis is an autoimmune skin disease associated with increased incidence and severity of chronic kidney disease and hypertension. The mechanisms linking psoriasis skin inflammation with these comorbidities remain unclear. We used flow cytometry, radiotelemetric blood pressure measurements, and histological and ELISA-based assessments of renal damage in mice with experimental psoriasis induced by keratinocyte-specific overexpression of Tie2 (KC-Tie2) and their littermate controls. Compared wit

Pustular psoriasis is a rare and severe variant of psoriasis characterized by the eruption of sterile pustules, which may present in distinct clinical patterns. The pathologic features of psoriasis, including keratinocyte hyperproliferation, neutrophilic infiltration, and immune dysregulation, are markedly accentuated. Generalized pustular psoriasis (GPP) displays clinical heterogeneity in age of onset, severity, and disease course. Several overlapping phenotypes are recognized. A variable relat

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

Psoriasis and psoriatic arthritis (PsA) are chronic immune-mediated inflammatory diseases associated with obesity, cardiometabolic disease, and mortality. The glucagon-like peptide-1 (GLP1) pathway has emerged as a key factor in the development of obesity and cardiometabolic disease. GLP1 receptor agonists demonstrably improve insulin resistance, dyslipidemia, obesity, and mortality, with emerging evidence suggesting potential benefit for psoriasis. To evaluate whether GLP1 biology influences ps

Background Psoriatic arthritis (PsA) is a complex immune-mediated heterogeneous inflammatory disease. Treatment decisions are challenging given the multisystem involvement. To further guide management strategies, we conducted a comparative analysis of the latest global guidelines highlighting the contrast in their approach to treat different PsA domains.Methods Major global guidelines for PsA management were reviewed, including American College of Rheumatology 2018 update, European Alliance of A

Background Placebo effects are a significant challenge in the conduct of clinical trials. We explored how global recruitment patterns influence the extent of placebo responses in randomized controlled trials of psoriatic arthritis and plaque psoriasis.Methods We conducted an analysis of 51 trials (6,843 patients; 52±5.7% female) in psoriatic arthritis, and 43 trials (5,671 patients; 32±7.1% female) in plaque psoriasis investigating biological and targeted synthetic therapeutics. We investigated

Psoriasis is a chronic inflammatory skin disease driven by immune dysregulation and often exacerbated by metabolic comorbidities. Glucagon-like peptide-1 receptor agonists (GLP-1RAs), initially developed for type 2 diabetes mellitus (T2DM) and weight management, have emerged as a promising treatment due to their anti-inflammatory and immunomodulatory properties. This review evaluates the clinical efficacy, mechanisms of action, and limitations of GLP-1RAs, such as liraglutide, exenatide, and sem

Background Psoriasis is associated with a significant comorbidity burden, especially cardiovascular and metabolic complications. Glucagon-like peptide-1 receptor agonists (GLP-1RA), such as semaglutide, used to treat obesity and diabetes, could potentially reduce comorbidity in patients with psoriasis.Objective To investigate all-cause mortality, cardiovascular, inflammatory, psychiatric outcomes, and adverse events in psoriasis patients treated with GLP-1RA.Methods This retrospective population
