Psoriatic arthritis is a systemic inflammatory disorder characterized by stiffness, pain, swelling, and tenderness of the joints and the surrounding ligaments and tendons, and psoriatic skin lesions.1
These manifestations are caused by an immune system that becomes dysregulated. Psoriatic arthritis has a significant negative impact on patient functionality, psychology, and quality of life. In one study, psoriatic arthritis was significantly associated with reduced work productivity.2-5
Many patients are diagnosed with psoriatic arthritis approximately 10 years after initial skin symptoms develop.6
