    【摘要】目的 研究血浆可溶性髓样细胞触发受体-1在脓毒症诊断中的价值。方法 检索PubMed、Ovid、Springer数据库、万方数据库中1991年到2012年国内外公开发表的关于血浆可溶性髓样细胞触发受体-1诊断脓毒症的相关文献,根据纳入和排除标准筛选文献并提取可用数据,通过Meta-DiSc及Stata软件进行Meta分析。结果 根据纳入标准筛选出7篇文献,各个研究截断值差异较大。异质性检验表明资料存在异质性(I2 > 50%,P<0.05),采用随机模型合并诊断指标。合并后的灵敏度 81%,95%CI: 0.76~0.86;特异度 81%,95%CI: 0.76~0.86;诊断优势比 30.03,95%CI: 7.89~114.37,SROC曲线的曲线下面积为0.905 9,Q*指数为0.837 6。Deek漏斗图显示无明显发表偏倚。结论 血浆可溶性髓样细胞触发受体-1用于脓毒症诊断具有一定的临床价值,但诊断脓毒症的最佳截断值有待进一步研究。

    【Abstract】Objective To investigate the value of plasma soluble triggering receptor expressed on myeloid cells-1 as a diagnosis marker of sepsis. Methods Articles on plasma soluble triggering receptor expressed on myeloid cells-1 as a marker of sepsis which were public published in the PubMed,Ovid,Springer,Wanfang database from 1991-2012 were searched and conducted a meta-analysis by MetaDiSc and Stata. Results Seven articles were selected to the meta-analysis according to the inclusion criteria, of which cut-off values varied signicantly from studies.Due to the data heterogeneity (I2>50%,P<0.05) , random model was used to pool the effect sizes. The overall combined effect sizes: sensitivity = 81% (95%CI : 0.76-0.86); specificity=81% (95%CI:0.76-0.86); DOR=30.03 (95%CI:7.89-114.37); AUC of SROC=0.905 9;Q*=0.837 6. Deek’s funnel plot showed little publication bias. Conclusions Plasma soluble triggering receptor expressed on myeloid cells-1 may be a useful adjunctive tool for the diagnosis of sepsis. However, further studies are needed in order to identify the best cut-off value in the diagnosis of sepsis.

    脓毒症(sepsis)指由于感染导致的全身性炎症反应综合征(systemic inflammatory response syndrome,SIRS),是一种具有致死风险的临床综合征[1-2],也是ICU患者最重要的死亡原因;然而由于其缺乏特异性的临床表现[3] ,临床上迫切需要一些容易获得且具有较高敏感度和特异度的诊断指标。

    目前诊断感染常用的指标包括白细胞、C反应蛋白和降钙素原等,除此之外,还有近些年发现的髓样细胞触发受体-1(triggering receptor expressed on myeloid cells-1,TREM-1),它主要表达在中性粒细胞、成熟的单核细胞和巨噬细胞,能够放大Toll样受体介导的炎症反应[2]。脓毒症时单核细胞膜上的TREM-1会明显增加,它的可溶解形式即可溶性髓样细胞触发受体-1(soluble triggering receptor expressed on myeloid cells-1,sTREM-1)可在体液中测得,从而可作为一个有用的感染诊断工具[2] 。例如,有学者通过Meta分析发现,胸水sTREM-1对感染性胸水具有良好的诊断准确度,可作为诊断感染性胸水的一个辅助工具[4]。, 百拇医药(陈都 陆士奇 徐峰 李伟)
