Biomarkers of intravenous immunoglobulin resistance and coronary artery lesions in Kawasaki disease

Abstract

Background

Currently, there are no reliable indicators for predicting intravenous immunoglobulin resistance and coronary artery lesions in the early stage of Kawasaki disease.

Methods

A total of 300 patients with Kawasaki disease were studied retrospectively. Laboratory data were compared between the intravenous immunoglobulin resistant (29 patients) and responsive groups, and between the groups with coronary artery lesions (48 patients) and without coronary artery lesions.

Results

The intravenous immunoglobulin resistant group had significantly higher D-dimer, globulin, interleukin-6 and serum ferritin levels in comparison to the intravenous immunoglobulin responder group. D-dimer level had a sensitivity of 87.0% and a specificity of 56.3% for predicting intravenous immunoglobulin resistance at a cutoff point of 1.09 mg/L. Globulin had a sensitivity of 62.1% and a specificity of 82.3% for predicting intravenous immunoglobulin resistance at a cutoff point of 34.7 g/L. Serum ferritin level had a sensitivity of 42.9% and a specificity of 88.8% for predicting intravenous immunoglobulin resistance at a cutoff point of 269.7 ng/mL. The patients with coronary artery lesions had higher D-dimer and tumor necrosis factor-α level. D-dimer level had a sensitivity of 50% and a specificity of 78.6% for predicting coronary artery lesions at a cutoff point of 1.84 mg/L. Based on analysis by multivariate logistic regression, serum ferritin and globulin were independent risks for intravenous immunoglobulin resistance, D-dimer was independent risk for coronary artery lesions.

Conclusions

Elevated serum ferritin, globulin and D-dimer levels are significantly associated with intravenous immunoglobulin resistance in Kawasaki disease. Moreover, serum D-dimer is significantly increased in Kawasaki disease with coronary artery lesions.
