Psoriatic arthritis is a chronic, immune-mediated, inflammatory arthropathy that presents with inflammation of the joints and entheses, including those of the axial skeleton, and is associated with increased mortality from cardiovascular disease. Diagnosis is primarily based on clinical phenotype because of the diversity of the associated features, which can include skin and nail disease, dactylitis, uveitis, and osteitis. Improved understanding of the pathogenesis of psoriatic arthritis has led to the development of effective biologics and small-molecular drugs targeting specific cytokines and signalling pathways, which can prevent disease progression and improve quality of life. ⋯ However, the precise mechanisms underlying the pathogenesis of psoriatic arthritis-which include genetics, environmental factors, and immune-mediated inflammation-are complex, and the relationship between disease of the joint and that of other domains is poorly understood. Improving our understanding of psoriatic arthritis pathogenesis could help to establish validated biomarkers for diagnosis, predict therapeutic response and remission, develop precision medicines, and predict which patients will respond to which therapy. We discuss advances in pathogenetic translational research that could inform these issues.

Psoriatic arthritis, or the broader term psoriatic disease, refers to an inflammatory disorder that affects multiple organs, including the skin and joints, and that also has related extra-articular manifestations and can have comorbidities. Patients with psoriatic disease have a substantial clinical burden. ⋯ The increase in therapeutic options, such as disease-modifying anti-rheumatic drugs, both biological and targeted synthetic, has revolutionised the treatment of skin and joint disease, and has prompted clinicians to use the full clinical picture of an individual patient to make rational treatment decisions. Current research is also focused on treatment strategies, including treat to target, early remission-induction, and tapering.
