Abstract:

It is estimated that two billion people have had hepatitis B virus (HBV) infection worldwide. Any immunocompromised status will change the state of HBV infection and lead to HBV reactivation. The consequences of reactivation could be asymptomatic, fulminant hepatitis, hepatic failure and even death. The reactivation rate of HBV ranges from 24% to 88% with different risk factors, and the mortality rate is higher than 10%. The risk factors include the use of biological agents and glucocorticoids, high level of viral load at baseline, and positive HBV surface antigen, etc. All candidates for chemotherapy and immunosuppressive therapy should be screened for HBV infection, and receive risk classification and then prevention and treatment, which is significant for preventing the hazard that caused by HBV reactivation.

Key words: Hepatitis B virus, Reactivation, Prophylaxis
