[Kawasaki disease in Mexican children]

Abstract

The records of 16 cases seen at Mexico Children's Hospital with a diagnosis of KD were reviewed. Mean age was three years; eight were infants, and males were dominant with a ratio of 4.3:1. Two cases occurred in sibling. Evidence of myocarditis was recognized in six, and 12 had coronary anomalies, including five with aneurysms. Two infants with severe coronary disease died, one suddenly with myocardial ischemia, and one with a ruptured aortic aneurysm. Another infant developed severe stenosis of the right coronary artery but remains asymptomatic. Two cases have persistent coronary ectasia and seven are asymptomatic with a normal echocardiogram. Predictors of coronary risk were correlated with clinical outcome. All six cases with 6 or more points had coronary anomalies, two developed giant aneurysms, two died and one has severe coronary stenosis. Of 10 cases with less than 6 points, four did not have coronary involvement, none developed giant aneurysms and none died nor developed severe coronary sequelae. Although KD has been sporadically reported in this country, the present series, the largest from a single institution, firmly establishes the presence of the disease in Mexico.
