腹水endocan对失代偿性肝硬化患者自发性腹膜炎的诊断价值研究
发布时间:2021-06-27 13:37
研究背景自发性细菌性腹膜炎(spontaneous bacterial peritonitis,SBP)是失代偿性肝硬化伴腹水患者最常见的感染,也是患者死亡的常见原因,早期使用抗生素治疗能极大改善患者预后,但是抗生素的普遍使用,使得肝硬化患者对常用抗生素的细菌耐药性增加,这将进一步增加SBP的病死率。SBP患者大部分都缺乏典型的临床表现,且腹水培养阳性率很低,这就需要我们积极寻找可靠的早期识别SBP的生物标志物,从而有针对性地进行抗生素治疗,以改善患者预后、利于合理使用抗生素。目的探索腹水中endocan水平对失代偿性肝硬化患者自发性细菌性腹膜炎(SBP)的诊断价值。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、肿瘤坏死因子-α(TNF-α)及白介素-6(IL-6)的浓度,采用logstic回归模型分析SBP的独立影响因素,斯皮尔曼相关性分析炎症指标间的相关性,ROC曲线分析腹水endocan对SBP的诊断价值。结...
