Risk Factors for Intravenous Immunoglobulin Non-responsiveness and Coronary Ectasia in Korean Patients With Kawasaki Disease

초록

We aimed to determine the risk factors for non-responsiveness to intravenous immunoglobulin (IVIG) and coronary ectasia in Korean children with Kawasaki disease (KD) and compare the efficacy of previously published Japanese and Chinese risk scoring systems in the same cohort. We retrospectively reviewed 459 KD cases diagnosed from January 1, 2013, to December 31, 2022. Age (odds ratio [OR]: 0.983; 95% confidence interval [CI]: 0.968-0.999), change in extremities (OR: 3.308; 95% CI: 1.530-7.151), neutrophils (OR: 1.078; 95% CI: 1.049-1.108), and alanine aminotransferase (OR: 1.002; 95% CI: 1.000-1.004) were identified as independent risk factors for IVIG non-responsiveness, and age (OR: 0.945; 95% CI: 0.902-0.989), C-reactive protein (OR: 1.092; 95% CI: 1.004-1.188), and creatinine kinase (OR: 1.004; 95% CI: 1.001-1.006) were identified as independent risk factors for coronary ectasia. Among previously published risk scoring systems, the Egami (area under the receiver operating characteristics curve [AUC]: 0.695; 95% CI: 0.651-0.737) for IVIG non-responsiveness and the Tang score (AUC: 0.726; 95% CI: 0.578-0.874) for coronary ectasia showed the highest predictive value for our study cohort.
