Key Points
- Kawasaki disease (KD) is a medium vessel vasculitis, one of two primary common vasculitis syndromes that predominantly affect children (the other being Henoch-Schönlein purpura/IgA vasculitis).
- KD typically presents in children under 5 years of age with an incidence in the US of 25–50/100,000, similar to that of type 1 diabetes.
- KD treated appropriately is associated with a low rate of mortality (approximately 0.08% case fatality rate in the largest series).
- However, in the developed world, KD is the most common cause of acquired cardiac disease in childhood, with 25% of untreated and 5% of treated cases developing coronary artery aneurysms.
- In infants less than 6 months of age, the risk of a coronary artery aneurysm is 50% even in KD patients treated with intravenous immunoglobulin (IVIG) within the first 10 days of illness.
- These recommendations provide guidance regarding diagnostic strategies, use of pharmacologic agents, and role of echocardiography for patients with suspected or confirmed KD.
