Abstract Objective To study the values of neutrophil-lymphocyte ratio (NLR) and platelet-lymphocyte ratio (PLR) in predicting the sensitivity to intravenous immunoglobulin (IVIG) in Kawasaki disease (KD). Methods A retrospective cohort study was conducted in 404 children with newly diagnosed KD. The data on routine blood tests, NLR, and PLR were collected before and after IVIG treatment. The receiver operating characteristic (ROC) curve was used to determine the cut-off values of NLR and PLR in predicting the insensitivity to IVIG. A logistic regression analysis was used to identify independent predictive factors for insensitivity to IVIG. Results Of all patients, 31 were insensitive to IVIG. Compared with the IVIG sensitivity group, the IVIG insensitivity group had a significantly higher incidence rate of coronary artery ectasia (P < 0.01), a shorter course of disease when IVIG therapy was initiated (P < 0.05), and significantly higher NLR, PLR, and C-reactive protein (CRP) level before and after treatment (P < 0.05). The optimal cut-off values for NLR and PLR to predict IVIG insensitivity were 4.36 and 162 before IVIG treatment and 1.45 and 196 after treatment. The multivariate regression analysis showed that the course of disease before IVIG treatment, CRP before IVIG treatment, and NLR and PLR before and after IVIG treatment were independent predictive factors for IVIG insensitivity. Conclusions NLR and PLR can be used to predict IVIG insensitivity in children with KD.
