The potential role of GLP-1 receptor agonists in the management of psoriatic disease: a scoping review

BackgroundPsoriatic disease (PsD) is a chronic systemic inflammatory condition associated with significant cardiometabolic comorbidities, including obesity, type 2 diabetes mellitus (T2DM), and cardiovascular (CV) disease. These comorbidities are interlinked via shared immunopathogenic mechanisms, notably chronic low-grade inflammation driven by Th1/Th17 cytokines such as TNF, IL-6, and IL-17. Obesity, in particular, exacerbates PsD severity and treatment resistance, underscoring the need for integrated therapeutic strategies. This scoping review investigates the biological rationale and evidence for the use of glucagon-like peptide-1 receptor agonists (GLP-1RAs) in PsD.FindingsOriginally developed for T2DM, GLP-1RAs have demonstrated efficacy in reducing weight and improving glycemic control and CV outcomes. Evidence also suggests immunomodulatory properties through modulation of key inflammatory pathways and immune cell activity. We examined studies addressing: (1) the impact of obesity, T2DM, and CV disease on PsD; (2) outcomes of GLP-1RAs in these comorbidities; and (3) their potential in related rheumatologic and dermatologic diseases. GLP-1RAs show promise in reducing PsD burden by improving metabolic parameters and reducing systemic inflammation. Early clinical and preclinical data suggest benefits also in rheumatoid arthritis, osteoarthritis, osteoporosis, psoriasis, and hidradenitis suppurativa.ImplicationsGLP-1RAs represent a novel, multifaceted therapeutic option in PsD, targeting both metabolic and inflammatory components. Further clinical trials are warranted to define their role in comprehensive PsD management and validate their disease-modifying potential.
