ObjectiveTo investigate the risk factors for short-term prognosis in patients with HBV-related acute-on-chronic liver failure (ACLF). MethodsA retrospective analysis was performed for the clinical data of 119 patients with HBV-related ACLF who were admitted to Mengchao Hepatobiliary Hospital of Fujian Medical University from October 2019 to October 2020, and according to their survival status on day 90, they were divided into death group and survival group. The patients were given antiviral therapy with entecavir or tenofovir. Related clinical data were collected, including alanine aminotransferase (ALT), aspartate aminotransferase, cholinesterase (ChE), albumin (Alb), cholesterol, alpha-fetoprotein, and HBV DNA at baseline, as well as the incidence rate of important complications. Model for End-Stage Liver Disease (MELD) score was also calculated. The t-test or the Mann-Whitney U test was used for comparison of continuous data between two groups, and the chi-squared test was used for comparison of categorical data between two groups; a logistic regression analysis was used to investigate the influencing factors for the 90-day prognosis of patients with HBV-related ACLF and establish a new predictive model; the receiver operating characteristic (ROC) curve was used to evaluate the diagnostic efficiency of the new model in predicting the prognosis of HBV-related ACLF. ResultsOf all patients, 33 died within 90 days, resulting in a mortality rate of 27.7%. There were significant differences between the survival group and the death group in age, ALT, Alb, ChE, MELD score, and incidence rates of hepatic encephalopathy, primary peritonitis, and hepatorenal syndrome (all P＜0.05). The logistic regression analysis showed that baseline hepatic encephalopathy (odds ratio ［OR］=10.404, 95% confidence interval ［CI］: 2.522-42.926, P=0.001), serum Alb at baseline (OR=0.853, 95%CI: 0.764-0.952, P=0.005), and MELD score at baseline (OR=1.143, 95%CI: 1.036-1.261, P=0008) were independent predictive factors for the short-term prognosis of patients with HBV-related ACLF. A new predictive model was established based on the combination of these three indices, and the ROC curve analysis showed that this new model had an area under the curve of 0.833, while MELD score had an area under the ROC curve of 0.672. ConclusionAs for the evaluation of the 90-day prognosis of patients with HBV-related ACLF, the new prognostic model established based on hepatic encephalopathy, Alb, and MELD score has a better predictive value than MELD score alone.
