目的 检测感染新生儿血清可溶性髓样细胞触发受体-1(soluble form of triggering receptors expressed on myeloid cell-1,sTREM-1)的水平,探讨sTREM-1在足月新生儿感染中的变化及其意义.方法 以上海交通大学附属儿童医院新生儿科85例足月新生儿为研究对象,根据感染情况分为重症感染组(27例),轻症感染组(28例)和非感染组(30例).感染组患儿在出现感染症状48 h内使用抗生素前采集静脉血1 ml;非感染组患儿在住院期间采集静脉血1 ml.重症感染组中合并器官功能障碍的患儿在出现感染症状的第3和7天再次采集静脉血各1 ml.采用酶联免疫吸附试验测定血清中sTREM-1水平,并采用方差分析进行组间比较.绘制受试者工作特性曲线确定sTREM-1的最佳界值,计算敏感性、特异性、阳性预测值、阴性预测值和约登指数.结果 (1)重症感染组sTREM-1水平为(91.2±47.3)pg/ml,高于轻症感染组[(68.8±30.4)pg/ml],轻症感染组又高于非感染组E(35.5±17.6)pg/ml],差异均有统计学意义(P均=0.000).(2)重症感染组中有17例存活,10例死亡;死亡患儿血清sTREM-1水平为(121.6±49.3)pg/ml,明显高于存活者[(73.1±34.9)pg/ml],差异有统计学意义(t=2.995,P=0.006).(3)重症感染组合并器官功能障碍的13例患儿中,存活者感染第1周内血清sTREM-1水平总体呈下降趋势,死亡患儿sTREM-1水平呈上升趋势,最佳界值为100.6 pg/ml.(4)将sTREM-1≥43.8 pg/ml作为阳性诊断标准,其曲线下面积为0.868,敏感性、特异性、阳性和阴性预测值及约登指数分别为85.5%、80.0%、0.887、0.750和0.655.结论 血清sTREM-1水平在新生儿感染时升高;重症感染患儿血清sTREM-1水平呈动态变化,其变化趋势可能与预后有关.

Objective To observe the changes of serum soluble form of triggering receptors expressed on myeloid cell-1 (sTREM-1) level in full-term newborns with infection and to investigate the relationship between serum sTREM-1 and neonatal bacterial infection.Methods Eighty-five full-term newborns admitted to the neonatal ward of Shanghai Children s Hospital of Shanghai Jiaotong University were selected into this study.According to the locations and severity of infection,patients were divided into 3 groups: severe infection group (n = 27),mild infection group (n = 28),non-infection group (n = 30).The samples of infection groups were collected before using antibiotics and within 48 h after infection symptom occurred; others were collected during hospitalization.For the neonates with organ dysfunction in the severe infection group,samples were also collected at the third and seventh day of infection.Serum sTREM-1 was measured by enzyme-linked immunosorbent assay.Analysis of variance was used to compare the difference between groups.Receiver operating characteristic (ROC) curve was used to calculate the sensitivity,specificity,positive and negative predictive value and Youden index.Results (1) Serum sTREM-1 level of severe infection group[(91.2±47.3) pg/ml] was significantly higher than that of mild infection group[(68.8 + 30.4) pg/ml] and non-infection group[(35.5±17.6) pg/ml],respectively (P<0.05).(2) Serum sTREM-1 level of the survival newborns (n= 17) in the severe infection group was lower than that of dead ones[(73.1±34.9) pg/ml vs (121.6±49.3) pg/ml,t= - 2.995,P = 0.006].(3) For the survival patients,the serum sTREM-1 level decreased in the first week of infection,while that of dead patients increased,the cut-off value was 100.6 pg/ml.(4) Based on the ROC analysis,43.8 pg/ml was selected as the the cut-off value,area under the curve was 0.868,and sensitivity was 85.5%,specificity 80.0%,positive predictive value 0.887,negative predictive value 0.750,Youden index 0.655.Conclusions Serum sTREM-1 level increases in neonatal infection.The change of serum sTREM-1 level in patients with severe infection is correlated to the prognosis.
