Abstract: Hepatitis B virus infection-related acute liver failure (HBV-ACLF) was a clinical syndrome
characterized by acute liver failure on the basis of chronic hepatitis and end-stage liver disease caused by
hepatitis B virus (HBV) infection, which was the main type of liver failure in China and with extremely
high short-term mortality. Basic research had found that the level of AFP was related to the short-term
prognosis of HBV-ACLF, which could be used to predict the short-term prognosis of patients with
liver failure. Clinical studies had found that the NHA-ACLF model (comprising neutrophils, hepatitis
B virus surface antigen and AFP), the TACIA scoring model (including total bilirubin, age, serum
creatinine, international normalized ratio and AFP), the artificial liver support system prognosis model
incorporating AFP (APM), and AFP quartile stratification all provided superior predictive value for
short-term prognosis in patients with HBV-ACLF compared to AFP alone.
