ABSTRACT
Scoring systems used to predict morbidity in children with Kawasaki disease (KD) have been developed and validated in Asian populations. The objective of this study was to assess their utility in predicting the development of coronary artery dilation in children with KD in North America. This was a secondary analysis of a National Institutes of Health / National Heart, Lung, and Blood Institute (NIH/NHLBI) Pediatric Heart Network public use dataset from a multicenter, randomized controlled trial of pulse steroid therapy in KD in a North American cohort. The primary outcome of interest was development of coronary artery dilation. The Harada, Kobayashi, Egami, and Sano scoring systems, originally developed to predict risk of intravenous immunoglobulin (IVIG) resistance in Kawasaki patients in Japan, were applied to this cohort. Subjects were kept in the analysis only if there were complete data for every element of each scoring system-Harada (n = 132), Kobayashi (n = 88), Egami (n = 139), and Sano (n = 82). Patients classified as high-risk by the Harada score were more likely to have significant coronary artery dilation (p = 0.042), were more likely to require IVIG retreatment (p = 0.002), and were more likely to require hospital readmission (p < 0.001). The Egami, Kobayashi, and Sano scores were not predictive for any measured outcome. The Harada score can be useful in identifying KD patients at risk for developing coronary artery dilation and IVIG resistance. The Harada score has demonstrated higher sensitivity but lower specificity, making it a valuable screening tool that may benefit from supplementary diagnostic methods.
