Has joint involvement lessened in Kawasaki disease?

Objective: Kawasaki disease (KD) is an acute systemic vasculitis affecting medium-sized arteries, particularly the coronary arteries. Classic diagnosis is based in prolonged fever and different clinical features, including acute arthritis. Our objective is to determine the prevalence of arthritis at the moment of the diagnosis, the response to intravenous immunoglobulin infusion and the relation with cardiac findings.
