Abstract |
|---|
Psoriatic arthritis (PsA) is a seronegative inflammatory spondyloarthropathy occurring in individuals with psoriasis. Psoriasis precedes joint disease in approximately 80% of PsA cases. The clinical course of PsA varies from mild arthritis to a severe, debilitating erosive arthropathy that affects functional capacity and quality of life of patients. The incidence of PsA is gender neutral, but a significant genetic component exists. Hallmark clinical features include dystrophic nail changes in the fingers or toes, dactylitis, and enthesitis. Many drugs indicated for use in rheumatoid arthritis have been found useful in the treatment of PsA, suggesting a similar immune-mediated etiology. Nonsteroidal anti-inflammatory drugs and intraarticular corticosteroids are often sufficient to manage mild PsA. Moderate to severe forms of the disease require the initiation of disease modifying anti-rheumatic drugs. Failure of two disease modifying antirheumatic drugs justifies the initiation of biologic therapy with tumor necrosis factor- inhibitors.
