白细胞介素-17对坏死性小肠结肠炎早产儿病死率的预测价值

目的 评估监测循环血白细胞介素-17(IL-17)预测坏死性小肠结肠炎(NEC)早产儿60 d病死率的价值.方法 回顾性纳入85例外科(n=35)或内科(n=50)治疗的NEC新生儿.在诊断NEC及术前检测血清IL-17水平,评估其预测价值.结果 60 d后病死率为20％(17/85),其中5例(10％)为内科治疗组,12例(34％)为外科治疗组.IL-17与30 d后病死率显著相关(OR 1.38;95％CI:1.14～1.67;P=0.001).外科治疗组术前IL-17水平(27～7 500 pg/mL,中位数2 625 pg/mL)较内科治疗组(中位数156 pg/mL)明显更高(P＜0.01).内科治疗组和外科治疗组NEC在曲线下面积的区别为0.82(95％CI:0.74～0.90),IL-17有检测意义的临界值为1 783 pg/mL(敏感度为90.5％,特异度为59.2％).结论 血清IL-17水平与NEC新生儿60 d病死率相关.

Value of interleukin-17 in predicting mortality rate of premature infants with necrotizing enterocolitis

Objective To evaluate the value of monitoring circular blood interleukin(IL)-17 for predicting 60 d mortality rate in premature infants with necrotizing enterocolitis(NEC).Methods A total of 85 neonates with surgically or medically treated NEC were retrospectively included.Serum IL-17 level was detected in diagnosing NEC and before preparing operation for evaluating its predictive value.Results The mortality rate after 60 d was 20 ％ (17/85),in which 5 (10 ％)was in the medical treatment group and 12(34％) in the surgical treatment group.The IL-17 level was significantly correlated with mortality rate after 30 d odds ratio (OR):1.38;CI:1.14-1.67;P=0.001].The preoperative IL-17 level in the surgical treatment group was 27-7 500 pg/mL(median 2 625 pg/mL),which was significantly higher than mean 156 pg/mL in the medical treatment group.The difference in the area under curve(AUC)between the medical treatment group and surgical treatment group was 0.82(CI:0.74-0.90).The critical value of IL-17 for detection significance was 1 783 pg/mL(sensitivity was 90.5％,specificity was 59.2％).Conclusion Serum IL-17 level is correlated with the mortality rate after 60 d.
