[Kawasaki disease].
Kawasaki disease (KD) is a febrile systemic vasculitis complicated by coronary and peripheral arterial aneurysms in 20% to 35% of untreated patients. It is reported as the commonest cause of acquired heart disease in children in developed countries, and may be a risk for adult ischaemic heart disease. Although KD has been reported all over the world, it is overexpressed among Asian populations, especially Japanese people. The annual incidence for 100,000 children under five years of age is reported to be 8.1 in the United Kingdom, 17.1 in the United States and 112 in Japan. The principal clinical feature is fever, accompanied by extremity changes, polymorphous rash, conjunctival injection, changes in lips and oral cavity, and cervical lymphadenopathy. The disease pathogenesis is still unknown and several theories have been proposed, including the possibility of an infection by a toxin-secreting microorganism and of a superantigen-driven process. Despite numerous efforts there is still no diagnostic test available for KD, and the diagnosis is based on clinical criteria after the exclusion of other diseases presenting with high persistent fever. Prompt diagnosis is critical, since the early administration of intravenous immunoglobulins and aspirin reduces the rate of coronary abnormalities to less than 5% of patients.
