Abstract

Objective

To investigate the effect of medium- or higher-dose acetylsalicylic acid (ASA) for treating acute-phase Kawasaki disease to prevent coronary artery aneurysm (CAA).

Study design

Among the children with acute Kawasaki disease investigated in the eighth nationwide survey in the Republic of Korea, 8456 children with adequate data were included in this study. The subjects were divided into 2 groups according to the use of medium- or higher-dose ASA (≥30 mg/kg/day), or-low dose ASA (3-5 mg/kg/day) during the acute febrile phase. Both z- score–based criteria and Japanese criteria for CAA were used.

Results

The prevalence of CAA based on z-score (24.8% vs 18.3%; P = .001) and on the Japanese criteria (19.0% vs 10.4%; P < .001) was higher in the 7947 patients who received medium- or higher-dose ASA compared with the 509 patients who received low-dose ASA. The use of medium- or higher-dose ASA was a significant predictor of CAA based on both sets of criteria by univariate analysis (based on z-score: OR, 1.472, 95% CI, 1.169-1.854, P = .001; based on Japanese criteria: OR, 2.013, 95% CI, 1.507-2.690, P < .001) and multivariate logistic regression analysis (OR, 1.527, 95% CI, 1.166-2.0, P = .003 and OR, 2.198, 95% CI, 1.563-3.092, P < .001, respectively).

Conclusions

The use of medium- or higher-dose ASA in acute Kawasaki disease did not prevent CAA. A future randomized controlled trial is needed to determine the optimum dose of ASA.
