What is Known:
• There are several risk scores developed in the Asian population to early identify patients with KD at risk for immunoglobulin-resistance and thus for coronary lesions.
• Data are scarce on their effectiveness in non-Asian children.
What is New:
• We present a comprehensive analysis of the ability of 3 Asian risk scores in a cohort of mostly Caucasian children to predict immunoglobulin resistance and coronary involvement.
• Low sensitivity and specificity of the Asian scores for immunoglobulin-resistance and coronary lesions suggest the need for criteria specific for different ethnicities.
