Psoriatic Arthritis

Psoriasis-Associated Arthritis

A form of inflammatory arthritis that develops in some people with psoriasis, causing joint pain, stiffness, and swelling.

Psoriatic arthritis affects up to 30% of patients with psoriasis and can involve peripheral joints, the spine, entheses, and nails. Like rheumatoid arthritis, it can cause progressive joint damage. Treatment parallels RA: NSAIDs for mild disease, conventional DMARDs (methotrexate), and biologics (TNF inhibitors, IL-17 inhibitors, IL-12/23 inhibitors) for moderate-to-severe disease.
