Treatment of Kawasaki Disease

Children with Kawasaki disease should be hospitalized and cared for by a physician who has experience with this disease. When in an academic medical center, care is often shared between pediatric cardiology and pediatric infectious disease specialists, although no infectious agent has been demonstrated. It is imperative that treatment be started as soon as the diagnosis is made to prevent damage to the coronary arteries.

Intravenous immunoglobulin (IVIG) is the standard treatment for Kawasaki disease and is administered in high doses with marked improvement usually noted within 24 hours. If the fever does not respond, an additional dose may have to be considered. IVIG by itself is most useful within the first 7 days of onset of fever, in terms of preventing coronary artery aneurysm.

Salicylate therapy, particularly aspirin, remains an important part of the treatment but salicylates alone are not as effective as Intravenous immunoglobulin. Aspirin therapy is started at high doses until the fever subsides, and then is continued at a low dose when the patient returns home, usually for 2 months to prevent blood clots from forming. Except for Kawasaki disease and a few other indications, aspirin is otherwise normally not recommended for children due to its association with Reye's syndrome.

Corticosteroids have also been used, especially when other treatments fail or symptoms recur, but in a randomized controlled trial, the addition of corticosteroid to immune globulin and aspirin did not improve outcome. [2]

There are also treatments for iritis and other eye symptoms.
