Chinese children with Kawasaki syndrome have a high incidence of coronary aneurysms (32%), comparable to Japanese children, with anemia identified as a significant risk factor.
High aneurysm rate with anemia association in this small Kawasaki cohort warrants vigilance; leaves open causality and generalizability pending larger studies.
A retrospective analysis of the clinical features and outcome of 39 Chinese children with Kawasaki syndrome was made. The mean age of onset was 2.7 years (range: 0.2-13 years). The male:female ratio was 2.9:1. One child presented with nephrotic syndrome. This renal manifestation has not been described in Kawasaki disease. Ten (32%) out of 31 patients were found to have coronary aneurysms by cross-sectional echocardiography. The only significant risk factor detected in this group of patients was anaemia (P less than 0.007). There was one (2.5%) death from acute myocardial infarction and the rest of the patients were clinically well with a mean follow-up period of 1 year (mean: 5-40 days). This study indicates that there is a high incidence of coronary aneurysm complicating Kawasaki syndrome in Chinese comparable with that reported in Japanese children.
