Abstract
Background: Intravenous immunoglobulin (IVIG) resistance, which defined that Kawasaki disease (KD) patients have recrudescence fever more than 36 hours after IVIG infusion, and its prediction is one of the primary clinical issues and study hotspots in KD. This study aimed to prospectively investigated the value of albumin-bilirubin grade (ALBI) in predicting IVIG resistance in KD, and assessed whether ALBI has more predictive value or accuracy than either ALB or TBil alone in predicting IVIG resistance.Methods: A total of 823 patients with KD were prospectively enrolled. The clinical and laboratory data were compared between IVIG-response group (n=708) and IVIG-resistance group (n=115). Multivariate logistic regression analysis was performed to identify the independent risk factors of IVIG resistance. Receiver operating characteristic (ROC) curves analysis was applied to assess the validity of ALBI, ALB, and TBil in predicting IVIG resistance. Results: ALBI was significantly higher in patients with IVIG resistance and was identified as an independent risk factor for IVIG resistance in KD. The parameter of ALBI ≥ –2.57 (AUC: 0.705, 95%CI: 0.672–0.736), ALB ≤ 33.0g/L (AUC: 0.659, 95%CI: 0.626–0.692), and TBil ≥16.0μmol/L (AUC: 0.626, 95%CI: 0.592–0.659), produced a sensitivity, specificity, PPV, and NPV of 0.617, 0.657, 0.226, 0.914, and 0.651; 0.374, 0.850, 0.289, 0.893, and 0.783; 0.269, 0.941, 0.425, 0.888, and 0.847, respectively.Conclusion: A higher ALBI was an independent risk factor for IVIG resistance. It yielded better predictive ability than ALB and TBil alone for initial IVIG resistance.
