摘 要: | 目的探讨单核细胞趋化蛋白1(MCP-1)表达量和单核细胞人类白细胞抗原-DR(mHLA-DR)表达率对脓毒症患者病情危重程度及预后的临床意义。
方法选取2014年12月至2016年2月在聊城市人民医院重症医学科就诊的脓毒症患者104例,根据预后分为生存组(63例)和死亡组(41例),所有患者发病后12 h内采集静脉血,收集评估脏器功能的指标,并进行序贯器官衰竭估计(SOFA)评分和急性生理与慢性健康状况评分系统Ⅱ(APACHEⅡ)评分,应用酶联免疫吸附测定法(ELISA)检测血清MCP-1的表达量,流式细胞仪检测外周血mHLA-DR的表达率,比较2组患者之间各项指标的差异,并分析其对病情危重程度及临床预后的评估价值及相关性。
结果入组的脓毒症患者,死亡组血清MCP-1表达量较生存组明显升高[(187.65±60.73)pg/ml vs(90.83±31.58)pg/ml,t=-10.65,P<0.01],外周血mHLA-DR表达率较生存组明显降低[(29.41±8.78)% vs(54.70±12.21)%,t=11.47,P<0.05],SOFA评分较生存组明显升高[(11.76±3.92)分vs(9.17±4.39)分,t=-3.28,P<0.01],APACHEⅡ评分明显高于生存组[(25.76±6.27)分vs (18.83±4.65)分,t=-6.47,P<0.05]。血清MCP-1表达量评估脓毒症患者预后的受试者工作特征(ROC)曲线下面积(AUC)为0.950[95%可信区间(CI)=0.911~0.989,P<0.001],根据ROC曲线确定MCP-1评估脓毒症患者死亡的最佳阈值为115.48 pg/ml时,其诊断敏感度为90.2%,特异度为87.3%。mHLA-DR表达率的ROC的AUC为0.952(95%CI=0.915~0.990,P<0.001),根据ROC曲线确定mHLA-DR评估脓毒症患者生存的最佳阈值为39.3%时,其诊断敏感度为88.9%,特异度为87.8%。SOFA评分的ROC的AUC为0.690(95%CI=0.591~0.790,P<0.002),根据ROC曲线确定SOFA评分评估脓毒症患者死亡的最佳阈值为8.5分时,其诊断敏感度为80.5%,特异度为57.1%。APACHEⅡ评分的ROC的AUC为0.805(95%CI=0.711~0.898,P<0.001),根据ROC曲线确定APACHEⅡ评分评估脓毒症患者死亡的最佳阈值为22.5分时,其诊断敏感度为75.6%,特异度为76.2%。所有入组患者血清MCP-1表达量与mHLA-DR表达率呈负相关(r=-0.872,P<0.001)。
结论MCP-1和mHLA-DR的表达水平可以反映脓毒症患者的病情危重程度,对评估预后具有一定的指导意义。

Abstract: | ObjectiveTo investigate the clinical value of t MCP-1 and monocyte human leukocyte antigen-DR (mHLA-DR) in severity and the prognosis of sepsis patients.
Method104 patients with sepsis were selected. Patients were classified into two groups (survival group (63 cases) and non-survival group (41 cases). Venous blood was collected in all patients within 12 hours after admission, and sequential organ failure assessment (SOFA) score and acute physiology and chronic health evaluation Ⅱ (APACHEⅡ) score were documented. Serum MCP-1 was detected by ELISA method and peripheral blood mHLA-DR by flow cytometer. We compared the differences between the two groups, and drew the receiver-operating characteristic curve (ROC) to investigate the clinical value of different indicators for the prognosis of sepsis patients. And we further analyzed the relationship between the MCP-1 and the mHLA-DR.
ResultFor all the enrolled sepsis patients, the expression of serum MCP-1 in non-survival group was significantly higher than in survival group (187.65±60.73) pg/ml vs (90.83±31.58) pg/ml, t=-10.65, P<0.01]. The level of the mHLA-DR in survival group was higher than non-survival group (54.70±12.21) % vs (29.41±8.78)% t=11.47, P<0.05]. The SOFA score in non-survival group was higher than in survival group (11.76±3.92) vs (9.17±4.39), t=-3.28, P<0.01]. The APACHEⅡ score in non-survival group was significantly higher than in survival group (25.76±6.27) vs (18.83±4.65), t=-6.47, P<0.05]. The MCP-1 death area under the curve (AUC) was 0.950 (P<0.001, 95%CI: 0.911-0.989), and the cut-off point was 115.48pg/ml, the sensitivity was 90.2%, the specificity was 87.3%. The mHLA-DR survival area under the curve (AUC) was 0.952 (P<0.001, 95%CI: 0.915-0.990), and the cut-off point was 39.3%, the sensitivity was 88.9%, the specificity was 87.8%. The SOFA score death area under the curve (AUC) was 0.690 (P<0.002, 95%CI: 0.591-0, 790), and the cut-off point was 8.5 points, the sensitivity was 80.5%, the specificity was 57.1%. The APACHEⅡ score death area under the curve (AUC) was 0.805 (P<0.001, 95%CI: 0.711-0.898), and the cut-off point was 22.5 points, the sensitivity was 75.6%, the specificity was 76.2%. The MCP-1 expression was negatively correlated with the mHLA-DR level (r=-0.872, P<0.01).
ConclusionThe expression of serum MCP-1 and peripheral blood mHLA-DR in sepsis patients can reflect the degree of disease, and help assess patients′ prognosis. |
