Predictors of intravenous immunoglobulin resistance and coronary artery aneurysm in patients with Kawasaki disease
Abstract
Patients with Kawasaki disease (KD) who have intravenous immunoglobulin (IVIG) resistance are at increased risk for development of coronary artery abnormalities. Although in Japan several risk scoring systems are able to predict patients with IVIG-resistant (KD), they do not accurately predict non-responders in other regions. The objectives of this study were to determine the predictors of IVIG resistance and coronary artery aneurysm (CAA) and to develop risk scoring systems for predicting IVIG-resistant KD in the Thai population. A total of 217 patients with KD between 2004 and 2014 were retrospectively reviewed. All patients including 116 with complete KD and 101 with incomplete KD were diagnosed and treated with 2 g/kg IVIG. Twenty-six patients (85% male) with IVIG-resistant KD had a reduced platelet count and increased neutrophil-to-lymphocyte ratio compared with those with an IVIG response. Fifty-five patients with CAA eight weeks after diagnosis had a longer duration of fever (≥8 days) and increased platelet count (≥550 × 109/L) than those with non-CAA. Based on analysis by multivariate logistic regression, haematocrit ≤30%, platelet count ≤300 × 109/L, aspartate aminotransferase ≥40 U/L and neutrophil-to-lymphocyte ratio...Continue Reading
