Pauciarticular disease is a disease of few joints. It most commonly affects the knees, elbows, wrists, and ankles. The joints are usually affected asymmetrically (one joint on one side). Children affected by pauciarticular disease usually have a positive antinuclear antibody (ANA) test and are prone to an inflammatory eye condition, iridocyclitis. Children with pauciarticular JRA generally do well with treatment.
