  • 摘要:   目的  分析肝硬化腹水患者血清和腹水中髓系细胞触发受体1(TREM-1)的表达水平,并探讨其与临床特征、炎症标志物的相关性,以及TREM-1在感染诊断和预后中的作用。  方法  选取2019年1月—2020年12月在石家庄市第五医院住院治疗的肝硬化腹水患者110例,根据腹腔感染情况分为感染组(n=72)和未感染组(n=38);在合并感染的患者中,根据预后情况将其分为好转组(n=38)与未好转组(n=34)。收集患者的临床资料及实验室检查指标。采集血清和腹水,应用酶联免疫吸附试验检测TREM-1水平。正态分布的计量资料两组间比较采用成组t检验;非正态分布的计量资料两组间比较采用Mann-Whitney U检验,多组间比较采用Kruskal-Wallis H检验。计数资料两组间比较采用χ2检验。各项指标之间的相关性采用Spearman相关分析。采用多因素Logistic回归分析影响肝硬化腹水合并感染患者预后的因素,受试者操作特征曲线(ROC曲线)评价各项指标的诊断和预后预测效能,并用Delong检验比较ROC曲线下面积(AUC)之间的差异。  结果  腹水和血清中的TREM-1水平存在显著正相关(r=0.50,P<0.001)。未好转组患者腹水TREM-1(Z=-2.391,P=0.017)和血清TREM-1(Z=-2.544,P=0.011)水平均明显高于好转组;感染组患者腹水TREM-1水平显著高于未感染组(Z=-3.420,P<0.001),而血清TREM-1在两组之间差异无统计学意义(P>0.05)。血清和腹水TREM-1水平与C反应蛋白(CRP)、降钙素原(PCT)、白细胞计数及中性粒细胞/淋巴细胞比值呈显著正相关(r值分别为0.288、0.344、0.530、0.510、0.534、0.454、0.330、0.404,P值均<0.05)。ROC曲线分析显示,PCT、CRP与血清或腹水TREM-1三者联合应用诊断肝硬化腹水合并感染时,AUC分别达0.715和0.740。多因素Logistic回归分析表明,CRP(OR=1.019,95%CI:1.001~1.038,P=0.043)和血清TREM-1(OR=1.002,95%CI:1.000~1.003,P=0.016)是影响肝硬化腹水合并腹腔感染患者预后的独立危险因素,两者联合预测不良预后的AUC为0.728。  结论  肝硬化腹水患者的TREM-1水平与感染程度及预后密切相关。联合检测TREM-1与CRP和PCT可提高对感染诊断的准确性,并有助于评估患者预后。
