Abstract

Psoriatic arthritis (PsA) is a heterogeneous chronic inflammatory musculoskeletal condition with complex pathophysiology. In recent years, understanding of the pathogenesis of PsA has improved substantially. Several genetic and inflammatory factors have been identified and studied as targets for new biologic disease-modifying therapies. This review presents findings from a detailed literature assessment conducted to identify genes and biomarkers associated with PsA and its most common comorbidities. This literature assessment identifies genes and biomarkers that may be predictive of the onset and severity of PsA, places them in the context of our understanding of PsA pathogenesis, and explores potential connections between the pathways involved in PsA and current biologic therapeutics used to treat PsA. Knowledge of the genetics and inflammatory factors associated with disease pathogenesis can support the targeted development of new biologic therapies and biomarkers for PsA.
