摘要:

[摘要] 目的:探讨中性粒细胞-淋巴细胞比值(NLR)在脓毒症诊断及预后中的评估价值。方法:收集大理大学第一附属医院健康体检者50例(健康对照组)、同期入住重症监护室的非脓毒症患者50例(病例对照组)及脓毒症患者78例(脓毒症组)的一般资料及实验室资料,评估NLR对脓毒症的诊断价值和预后判断价值,分析判断NLR与序贯器官衰竭(SOFA)评分及降钙素原(PCT)的相关性,筛选NLR对脓毒症患者28 d病死率的最佳预测阈值和患者预后危险因素。结果:脓毒症组NLR水平较健康对照组和病例对照组显著升高,脓毒症组中死亡患者NLR水平显著高于生存患者,差异有统计学意义(P<0.01);NLR在脓毒症诊断和预后判断的受试者操作特征曲线的曲线下面积分别为0.810.75,并与SOFA评分、PCT呈正相关(P<0.001);NLR9.00的脓毒症患者28 d病死率显著升高(P<0.001);NLR在多元Logistic回归分析中OR值为1.128,调整混杂因素后OR值仍大于1。结论:NLR对脓毒症早期诊断的效能良好,对预测患者28 d病死率有一定价值。

Abstract:

AbstractObjectiveTo investigate the value of neutrophil-lymphocyte ratioNLRin the diagnosis and prognosis of sepsis.MethodsThe general and laboratory data of 50 physical examinershealthy control group), 50 non-septic patientscase control groupand 78 sepsis patientssepsis groupwere collected in the First Affiliated Hospital of Dali University. To evaluate the diagnostic value and prognostic value of NLR for sepsis,  the correlation between NLR and sequential organ failure assessment SOFAscore and procalcitoninPCTwas analyzedand the best prediction threshold of NLR for 28-day mortality rate and patient prognostic risk factors in the patients with sepsis were screened. ResultsThe NLR level in the sepsis group was significantly higher than that in the healthy control group and the case control groupand the NLR level of the dead patients was significantly higher than that of the surviving patients in the sepsis groupand the differences were statistically significantP<0.01. The area of NLR under ROC curve for diagnosis and prognosis of sepsis was 0.81 and 0.75respectivelyand was positively correlated with SOFA score and PCTP<0.001. The 28-day mortality rate of sepsis patients with NLR9.00 was significantly higherP<0.001. The OR value of NLR in the multiple Logistic regression analysis was 1.128and the OR value was still greater than 1 after adjustment for confounding factors. ConclusionNLR has a good diagnostic efficacy for sepsis and has a certain value in predicting the 28-day mortality rate of patients.
