    Abstract:
    INTRODUCTION: Multiple scoring systems for predicting intravenous immunoglobulin (IVIG) resistance have been developed. Although low-scoring patients with Kawasaki disease (KD) have a favorable prognosis, many develop coronary artery aneurysms (CAAs). Herein, we determined the risk factors for CAA development among patients with KD with low risk of IVIG resistance. METHODS: We compared 14 scoring systems for predicting IVIG resistance among patients with KD hospitalized from 2003 to 2022. Patients were risk stratified using an optimal scoring system. Association between baseline characteristics and CAA development was assessed within the low-risk group. RESULTS: Overall, 664 pediatric patients with KD were included; 108 (16.3%) had IVIG resistance, and the Liping scoring system had the highest area under the curve (0.714). According to this system, 444 (66.9%) patients with KD were classified as having low risk of developing IVIG resistance (<5 points). CAA development was significantly associated with male sex (odds ratio [OR], 1.946; 95% CI: 1.015-3.730), age <6 months at fever onset (OR, 3.142; 95% CI: 1.028-9.608), and a baseline maximum Z score of ≥2.72 (OR, 3.451; 95% CI: 2.582-4.612). CAA incidence increased with the number of risk factors, and comparisons with a Kobayashi score of <5 points among patients with KD revealed similar results. CONCLUSIONS: Predicting the response to IVIG might help further reduce CAA development in patients with KD.
