摘要

摘要: 目的探讨肝硬化患者发生隐匿性肝性脑病(CHE)的危险因素，并分析其对预后的影响。方法选择2019年9月—2020年6月重庆市某三甲医院的416例肝硬化患者为研究对象，根据是否发生CHE分为CHE组(n=212)和非CHE组(n=204)，收集临床资料和实验室检查结果，并实施6个月随访。正态分布的计量资料两组间比较采用t检验，不服从正态分布的计量资料两组间比较采用Mann-Whitney U检验；计数资料两组间比较采用χ²检验、连续校正χ²检验或Mann-Whitney U检验。经单因素和多因素logistic回归分析发生CHE的危险因素。结果 CHE的发生率为51%，单因素分析发现年龄、病程、HE病史、感染、腹水、电解质紊乱、肝肾综合征、Child-Pugh肝功能分级、凝血酶原时间、总胆红素、肌酐、血小板、凝血酶原活动度、白蛋白、MELD评分等是CHE的影响因素(P值均＜0.05)；多因素分析表明HE病史(OR=10.848，95%CI：4.971~23.674)、经颈静脉肝内门体分流术(TIPS)(OR=4.334，95%CI：1.203~15.621)、Child-Pugh肝功能分级(OR=4.968, 95%CI：1.299~18.992)、MELD评分(OR=1.253，95%CI：1.161~1.352)是CHE的独立预测因子(P值均＜0.05)；CHE组患者的中短期再入院、HE和死亡发生率均高于非CHE组(P值均＜0.05)。结论 CHE发生率较高，且影响患者预后，既往HE病史、TIPS术后、Child-Pugh分级C级和MELD评分较高的患者应警惕CHE的发生，早发现、早筛查、早干预，以最大限度改善肝硬化患者预后。

Abstract: Objective To investigate the risk factors for covert hepatic encephalopathy (CHE) in patients with liver cirrhosis and their influence on prognosis. Methods A total of 416 patients with liver cirrhosis who were hospitalized in a grade A tertiary hospital in Chongqing from September 2019 to June 2020 were enrolled in the study, and according to the presence or absence of CHE, they were divided into CHE group with 212 patients and non-CHE group with 204 patients. Clinical data and laboratory examination results were collected, and follow-up was performed for 6 months. The t-test was used for comparison of normally distributed continuous data between groups, and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between groups; the chi-square test, the continuous correction chi-square test, and the Mann-Whitney U test were used for comparison of categorical data between groups. Univariate and multivariate logistic regression analyses were used to analyze the risk factors for CHE. Results The incidence rate of CHE was 51%. The univariate analysis showed that age, course of disease, the medical history of hepatic encephalopathy (HE), infection, ascites, electrolyte disturbance, hepatorenal syndrome, Child-Pugh class, prothrombin time, total bilirubin, creatinine, platelet, prothrombin activity, albumin, and Model for End-stage Liver Disease (MELD) score were the influencing factors for CHE (all P < 0.05). The multivariate logistic regression analysis showed that the medical history of HE (OR=10.848, 95% CI: 4.971-23.674, P < 0.05), transjugular intrahepatic portosystemic shunt (TIPS) (OR=4.334, 95%CI: 1.203-15.621, P < 0.05), Child-Pugh class (OR=4.968, 95%CI: 1.299-18.992, P < 0.05), and MELD score (OR=1.253, 95%CI: 1.161-1.352, P < 0.05) were independent predictive factors for CHE (P < 0.05). The follow-up study showed that CHE had an effect on the short-or medium-term readmission, HE, and death of patients (all P < 0.05). Conclusion CHE has a relatively high incidence rate and greatly affects the prognosis of patients with liver cirrhosis. The development of CHE should be taken seriously in patients with a past history of HE, a history of TIPS, Child-Pugh class C liver function, and a high MELD score, and identification, screening, and intervention should be performed as early as possible to improve the prognosis of patients with liver cirrhosis.
