摘要:

目的 探讨可溶性CD163(sCD163)联合Charlson指数对肝硬化患者发生食管静脉曲张出血的预测价值。方法 选取2016年4月—2018年4月浙江大学医学院附属金华医院肝硬化患者100例作为建模组。收集所有患者的一般资料和实验室检测结果。根据随访期间是否发生食管静脉出血分为出血组(32例)和未出血组(68例)。另选取2018年6月—2020年6月浙江大学医学院附属金华医院肝硬化患者50例作为验证组。采用Logistic回归分析评估肝硬化患者食管静脉曲张出血的危险因素。构建列线图模型,并通过验证组进行外部验证。采用受试工作者特征(ROC)曲线和校准曲线评价列线图模型的区分度和准确性,评价sCD163和Charlson指数单项检测和联合检测判断肝硬化患者发生食管静脉曲张出血的效能。结果 建模组和验证组之间一般资料和实验室检测结果差异均无统计学意义(P>0.05)。出血组肝腹水发生情况、食管静脉曲张程度、红色征、门静脉内径、脾静脉内径、Charlson指数和凝血酶原时间(PT)、sCD163、D-二聚体(DD)水平均显著高于未出血组(P<0.05),其他指标2个组之间差异均无统计学意义(P>0.05)。多因素Logistic回归分析结果显示,有肝腹水、重度食管静脉曲张、有红色征、门静脉内径增大、sCD163升高和Charlson指数增高为肝硬化患者食管静脉曲张出血的危险因素[比值比(OR)值分别为2.124、1.865、2.001、2.412、1.685、2.623,95%可信区间(CI)分别为1.235~3.024、1.425~2.563、1.121~3.221、1.785~3.500、1.247~2.875、2.013~3.245]。ROC曲线分析结果显示,sCD163和Charlson指数单项和联合检测判断肝硬化患者食管静脉曲张出血的曲线下面积分别为0.846、0.852、0.889。ROC曲线和校准曲线均显示构建的列线图模型具有良好的区分度和准确度。结论 sCD163联合Charlson指数对肝硬化患者发生食管静脉曲张出血有良好的预测价值。

Abstract:

Objective To investigate the predictive value of soluble CD163(sCD163) combined with Charlson index for esophageal variceal bleeding in patients with liver cirrhosis. Methods Totally,100 patients with liver cirrhosis from Jinhua Hospital of Zhejiang University School of Medicine from April 2016 to April 2018 were enrolled as modeling group. The general data and clinical laboratory determination results were collected. According to whether esophageal variceal bleeding occurred during the follow-up period,they were classified into bleeding group(32 cases) and non-bleeding group(68 cases). Another 50 patients with liver cirrhosis from Jinhua Hospital of Zhejiang University School of Medicine from June 2018 to June 2020 were enrolled as validation group. Logistic regression analysis was used to evaluate the risk factors for esophageal variceal bleeding in patients with liver cirrhosis. A column chart model was established,and a validation group for external validation was used. Receiver operating characteristic(ROC) curve and calibration curve were used to evaluate the discrimination and accuracy of the column chart model. ROC curve was used to evaluate the efficacy of single and combined determinations of sCD163 and Charlson index in determining esophageal variceal bleeding in patients with liver cirrhosis. Results There was no statistical significance in general data and clinical laboratory determination results between modeling group and validation group(P>0.05). The incidence of hepatic ascites,degree of esophageal varices,red sign,portal vein diameter,splenic vein diameter,Charlson index,prothrombin time(PT),sCD163 and D-dimer(DD) levels in bleeding group were higher than those in non-bleeding group(P<0.05),and there was no statistical significance in the other indicators between the 2 groups(P>0.05). The presence of hepatic ascites,severe esophageal varices,red sign and increased portal vein diameter,sCD163 and Charlson index were risk factors for esophageal variceal bleeding in patients with liver cirrhosis [odds ratios(OR) were 2.124 , 1.865 , 2.001 , 2.412 ,1.685 and 2.623 ,95% confidence intervals(CI) were 1.235-3.024 , 1.425-2.563 , 1.121-3.221 , 1.785-3.500 , 1.247-2.875 and 2.013-3.245,respectively]. The areas under curves for single and combined determinations of sCD163 and Charlson index to determine esophageal variceal bleeding in patients with liver cirrhosis were 0.846,0.852 and 0.889,respectively. The ROC curve and calibration curve both showed that the constructed column chart model had good discrimination and accuracy. Conclusions The combined determination of sCD163 and Charlson index has good predictive value for esophageal variceal bleeding in patients with liver cirrhosis.
