Reactive Arthritis
Key Points
Reactive arthritis is a form of spondyloarthropathy that is triggered by infection and typically occurs after a sexually transmitted or enteric infection. Manifestations can include arthritis (usually asymmetric and involving large lower extremity joints and toes), enthesopathy, mucocutaneous lesions, conjunctivitis, and nonpurulent genital discharge (eg, urethritis, cervicitis). Confirm the diagnosis with typical arthritic findings plus either symptoms or history of recent genitourinary or gastrointestinal infection or a characteristic extra-articular finding. Treat with nonsteroidal anti-inflammatory drugs (NSAIDs) and sometimessulfasalazine.
