Role of Kobayashi Risk Scoring for Determining Refractory Kawasaki Disease

Coronary complications are common in children with Kawasaki disease (KD). Administration of intravenous immunoglobulin (IVIG) during the first 10 days will result in lower coronary complications. It is useful to predict if a patient will develop coronary complications or not. Objectives: We designed this study to evaluate the role of Kobayashi risk scoring for determining refractory KD. Methods: Medical records of all cases withKDwere reviewed and demographic data, previous history, coronary artery involvement, laboratory findings, and days with fever were extracted for all cases. Kobayashi score was calculated. Results: A total of 168 cases enrolled. There was no significant difference regarding Kobayashi score in different groups regarding coronary involvement. In cases without coronary involvement, 93.5% were classified as low risk, in one and two vessels involvement groups, all were categorized as low risk, and among three vessels involvement cases, 75% were known as low risk. Conclusions: Kobayashi score is not useful for predicting severity of coronary involvement in Kawasaki disease.
