81
Describe the treatment for Reactive arthritis (Reiter's syndrome).
NSAIDs.
Reactive arthritis
Reactive arthritis, although not a form of juvenile idiopathic arthritis, can present in adolescence, and like ERA, has an association with HLA-B27 positivity. The classic triad of arthritis, conjunctivitis and urethritis is not present in all cases. Enteric or genitourinary infections, including sexually transmissible infections (STIs; eg chlamydia), are typical triggers and should be considered in adolescents presenting with arthritis and relevant symptoms on systems review.14 The pattern of arthritis is variable; however, it most commonly involves the lower limbs, and prominent pain and erythema are classically described. Differentiating reactive arthritis from juvenile idiopathic arthritis can be challenging; however, reactive arthritis is generally self‑limited, requiring treatment with NSAIDs only. RACGP
