文摘目的探索肝硬化腹水患者的腹水endocan水平在自发性腹膜炎(spontaneous bacterial peritonitis,SBP)诊断中的作用。方法纳入2018年1月至2019年6月在我院住院的失代偿性肝硬化腹水患者161例,其中SBP组35例,非SBP组126例,留取入院时腹水标本,同时收集人口学资料及实验室检查资料,用ELISA方法检测腹水中endocan浓度,采用logstic回归模型分析SBP的独立影响因素,ROC曲线分析腹水endocan对SBP的诊断价值。结果腹水endocan水平在SBP组显著高于非SBP组[398.451(318.762~460.673)pg/mL vs 199.838(133.366~303.226)pg/mL,P<0.001]。logistic回归模型进行SBP影响因素分析结果显示腹水endocan为SBP的独立危险因素[OR=1.008(95%CI为1.004~1.012),P<0.001]。ROC曲线分析显示腹水endocan诊断SBP的曲线下面积(AUC)为0.822(P<0.001),临界值为280.983pg/ml时敏感性为88.57%,特异性为70.63%,在年龄大于等于60岁和小于60岁患者中,腹水endocan诊断SBP的AUC分别为0.852和0.789。结论腹水endocan水平是肝硬化腹水患者SBP的独立危险因素,是SBP有价值的诊断指标,且在年龄大于等于60岁患者的诊断价值更大。
