Studying Clinical, Biologic and Echocardiography Criteria to Predict a Resistant Kawasaki Disease in Children.

Background: Resistant Kawasaki disease (KD) represents 10%-15% of KD patients and increases risk of coronary artery abnormalities (CAAs). Different scores exist to predict resistant KD but only in Japanese population, although a French team has recently proposed a new scoring system. The principal objective of this study is to establish criteria to predict resistant KD in our representative French population.
