Abstract

OBJECTIVE:

To investigate the independent risk factors of influencing short-term survival and prognosis of patients with HBV-related acute-on-chronic liver failure (HBV-ACLF).

METHODS:

The clinical data of 338 HBV-ACLF patients hospitalized from January 2007 to December 2010 were collected and analyzed by a Cox regression model.

RESULTS:

The Cox regression analysis showed that gastrointestinal hemorrhage, hepatorenal syndrome, electrolyte imbalance and hepatic encephalopathy could significantly increase their recent mortality risks. And the values of relative risk (RR) were 2.526, 2.356, 2.068 and 1.896 respectively. Prothrombin activity (Exp(β): 0.821) and opportunity of antiviral therapy (Exp(β) of early stage: 0.526; Exp(β) of medium stage: 0.601) were protective factors of reduced mortality.

CONCLUSIONS:

Gastrointestinal hemorrhage, hepatorenal syndrome, electrolyte imbalance, hepatic encephalopathy, prothrombin activity and opportunity of antiviral therapy are independent risk factors of influencing short-term survival and prognosis of HBV-ACLF patients. The combination of MELD score and multivariate analysis is a more scientific method of determining the prognosis of HBV-related ACLF.
