摘　　要：目的 探讨中性粒细胞与淋巴细胞比值(NLR)和淋巴细胞与单核细胞比值(LMR)对脓毒症患者诊断和预后的价值。方法 回顾性分析2022年1-12月苏州大学附属第一医院感染病科诊治的脓毒症患者47例(脓毒症组)、有感染但未诊断为脓毒症患者31例(感染组)和同时期健康体检者25名(正常对照组)。脓毒症组根据临床诊断及预后进一步分为未休克组(32例)、休克组(15例)及生存组(38例)、死亡组(9例)。检测降钙素原(PCT)、C反应蛋白(CRP)及血常规项目。比较不同组间的差异,用Spearman相关性分析NLR、LMR与PCT、CRP、淋巴细胞(Lym)、单核细胞(Mon)、中性粒细胞(Neu)、血小板(Plt)及SOFA 评分之间的相关性,通过绘制受试者工作特征(ROC)曲线评价NLR、LMR对脓毒症的诊断价值。结果 脓毒症组、感染组和正常对照组的NLR分别为12.54(7.53,23.42)、3.85 (1.83,5.64) 和1.71(1.39,2.20),LMR分别为1.58(1.07,3.03)、2.81(1.53,4.76)和5.16(4.04,6.59)。NLR与LMR呈负相关,相关系数为-0.469(P<0.05)。脓毒症未休克组和休克组的NLR7分别为6.56(3.90,10.72)和15.20(7.53,27.31),入院后7 d NLR-入院后3 d NLR(ΔNLR7)分别为-1.64(-5.75,0.41)和1.98(-0.48,13.79),休克组均显著高于未休克组(P均<0.05);脓毒症生存组和死亡组的NLR7分别为7.10(4.09,12.96)和15.20(10.45,32.82),ΔNLR7分别为 -0.65(-5.58、1.58)和5.02(-1.12,17.06),死亡组均显著高于生存组(P均<0.05)。脓毒症未休克组和休克组的LMR7分别为2.22(1.64,3.78)和1.29(0.66,2.03),入院后7 d LMR-入院后3 d LMR(ΔLMR7)分别为0.38(-0.37,1.17)和-0.19(-0.78,0.25),休克组均显著低于未休克组(P均<0.05);脓毒症生存组和死亡组LMR7分别为2.12(1.49,3.42)和1.09(0.53,1.78),死亡组显著低于生存组(P<0.05)。NLR诊断脓毒症的AUC为0.959 1(95%CI:0.910 5-1.000 0),最佳截断值为4.16;LMR诊断脓毒症的AUC为0.913 6(95%CI:0.846 4-0.980 8),最佳截断值为3.21。结论 NLR和LMR可用于脓毒症严重程度及预�Objective To investigate the value of neutrophil to lymphocyte ratio(NLR)and lymphocyte to monocyte ratio(LMR)in the diagnosis and prognosis of patients with sepsis.Methods From January 2022 to December 2022,patients in the First Affiliated Hospital of Soochow University were recruited in this study,including 47 patients with sepsis(sepsis group),31 with infection but not diagnosed as sepsis(infection group),and 25 healthy individuals(control group)were simultaneously chosen.Patients with sepsis were assigned to non-shock group(32 cases)or shock group(15 cases),survivors group(38 cases)or deaths group(9 cases).Procalcitonin(PCT),C-reactive protein(CRP)and routine blood tests were analyzed and compared between groups.Spearman’s correlation test was used to analyze the correlation among NLR,LMR and PCT,PCR,lymphocyte,monocyte,neutrophil,platelet and SOFA scores,the diagnostic value of NLR and LMR in sepsis was evaluated by plotting the receiver operating characteristic(ROC)curve.Results The NLR was 12.54(7.53,23.42)in sepsis group,3.85(1.83,5.64)in infection group,and 1.71(1.39,2.20)in normal control group.The corresponding LMR was 1.58(1.07,3.03),2.81(1.53,4.76),and 5.16(4.04,6.59),respectively.NLR was negatively correlated with LMR(rs=-0.469,P<0.05).The NLR on day 7(NLR7)was 6.56(3.90,10.72)in the non-shock group and 15.20(7.53,27.31)in shock group.The correspondingΔNLR7 was-1.64(-5.75,0.41)and 1.98(-0.48,13.79)in the two groups.The shock group had significantly higherΔNLR7 than the non-shock group(P<0.05).NLR7 was 7.10(4.09,12.96)in the survivors and 15.20(10.45,32.82)in the deaths group.The correspondingΔNLR7 was-0.65(-5.58,1.58)and 5.02(-1.12,17.06)in the two groups.The deaths group had significantly higherΔNLR7 than the survivors group(P<0.05).The LMR on day 7(LMR7)was 2.22(1.64,3.78)in the non-shock group and 1.29(0.66,2.03)in shock group.The correspondingΔLMR7 was 0.38(-0.37,1.17)and-0.19(-0.78,0.25)in the two groups.The shock group had significantly lowerΔLMR7 than the non-shock group(P<0.05).LMR7
