Altered Lipid Metabolism in Psoriatic Arthritis: A Comprehensive Review

Psoriatic arthritis (PsA) is a chronic inflammatory disorder affecting both the joints and skin. Beyond musculoskeletal manifestations, patients with PsA frequently exhibit alterations in lipid metabolism, contributing to an increased risk of cardiovascular disease. Dyslipidemia in PsA arises from multiple mechanisms, including systemic inflammation, insulin resistance, and imbalances in adipokines such as leptin, adiponectin, and resistin. A structured literature search was conducted in PubMed, Scopus, and Web of Science to identify relevant studies on lipid metabolism in psoriatic arthritis, and the evidence was synthesized narratively. PsA is also commonly associated with obesity and metabolic syndrome, further exacerbating dyslipidemia and cardiovascular risk. Interventions including weight loss, lifestyle modification, and anti-inflammatory treatments have been shown to improve lipid profiles and clinical outcomes. This review provides a comprehensive overview of current knowledge on altered lipid metabolism in PsA, highlighting underlying mechanisms, clinical implications, and therapeutic strategies to reduce cardiovascular risk.
