Objective To assess the neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR) and systemic immune-inflammatory index (SII), as diagnostic markers for neonatal sepsis. Methods This retrospective study involve neonates with sepsis and healthy neonates as controls. NLR, PLR, and SII were compared between groups. Result In total, 60 neonates with sepsis and 60 healthy controls were involved in the study. Compared with controls, the sepsis group had higher values for NLR, PLR and SII. Logistic regression analysis suggested that the NLR, PLR and SII were independent risk factors for neonatal sepsis. In addition, receiver operating characteristic (ROC) curve analysis indicated that the NLR, PLR and SII were reliable predictors of neonatal sepsis and SII had the best predictive value. Conclusions NLR, PLR and SII appear to be useful indicators for predicting neonatal sepsis.
