妊娠晚期母体血清中性粒/淋巴细胞比值与早产发生风险相关性研究

摘要

目的 探讨妊娠晚期母体血清中性粒/淋巴细胞比值(NLR)水平与早产发生风险相关性.方法 回顾性分析2016年1月至2016年12月在我院进行常规产前检查并分娩早产患者100例,健康产妇100例,共200例研究对象的临床资料.比较两组孕妇晚孕期的几种血清炎症指标(外周血白细胞、中性粒细胞数、淋巴细胞数、C-反应蛋白(CRP)、NLR,利用多因素Logistic回归分析确定早产发生独立危险因素,建立模型,绘制模型受试者工作特征曲线(ROC),并记录曲线下面积以分析晚孕期不同血清炎症指标预测早产发生的临床价值.结果 与外周血白细胞、中性粒细胞数、淋巴细胞数、CRP相比,NLR预测早产发生风险的曲线下面积、灵敏度、特异性较高.结论 晚孕期NLR增高可作为预测早产发生风险的一项有效指标.%Objective The aim of this study was to investigate the association between maternal serum lev-el of neutrophil-lymphocyte ratio(NLR)and preterm labor in late stage of pregnancy. Methods In this retrospec-tive analysis of 200 pregnant women who underwent routine prenatal examination and delivered from January 12016 to December 312016 in the Maternal and Child Health family planning services,Xinhui District,Jiangmen city. The patients were divided into the PIR group(n = 100)and the control group(n = 100). The levels of leuko-cytes,neutrophils,lymphocytes,CRP and NLR of the two groups were compared. Multivariate analysis was per-formed to identify independent risk factor. Logistic regression model was established and the area under the receiver operating characteristic curve(ROC)was recorded for analysis of the prognostic value of different serum inflamma-tory makers in late stage of pregnancy. Results The NLR predict premature occurrence of AUC,the sensitivity and specificity of which were higher than those of peripheral blood leukocyte,neutrophil count,lymphocyte count and CRP. Conclusion Increased NLR in late stage of pregnancy could serve as an effective factor to predict the risk of preterm labor.
