Diagnostic Value of Neutrophil/lymphocyte Ratio and Platelet/lymphocyte Ratio in Premature Rupture of Membranes Complicated by Sepsis

Objective: To investigate the predictive value of neutrophil/lymphocyte ratio (NLR) and platelet/lymphocyte ratio (PLR) in premature rupture of membranes complicated by sepsis. Study Design: A descriptive study. Place and Duration of Study: Department of Paediatrics, Affiliated Hospital of Yanbian University, China, from January 2020 to June 2021. Methodology: Ninety-nine children with premature rupture of membranes and sepsis were included as group A and 99 children without sepsis were included as group B. Logistic regression analysis was used to analyse the risk factors for premature rupture of membranes complicated by sepsis. The diagnostic value of PLR and NLR in sepsis complicated by premature rupture of membranes was assessed by subject operating characteristic curve (ROC) curves. Results: Univariate analysis showed significant differences between groups A and B in terms of mode of delivery, lymphocyte count, platelets, PLR and NLR (p <0.05). Logistic regression analysis showed that mode of delivery, platelets, PLR and NLR were independent risk factors for premature rupture of membranes complicated by sepsis (p <0.05). The ROC area for PLR was 0.781 (95% CI: 0.718-0.844, p <0.001), which was greater than that for NLR when premature rupture of membranes complicated by sepsis was predicted. When the PLR was >93.072, the sensitivity of predicting premature rupture of membranes complicated by sepsis was 67.7% and the specificity was 79.8%. Conclusion: PLR and NLR have a high predictive value for premature rupture of membranes complicated by sepsis. Among them, the predictive value of PLR was greater than NLR.
