Antiviral treatment in patients with hepatitis B virus infection receiving chemotherapy

Reactivation of hepatitis B virus (HBV) is a frequent complication of chemotherapy in patients with HBV infection. Reactivation is characterized by increased levels of serum HBV DNA, abnormal liver function and hepatic failure. HBV reactivation inevitably leads to disruption of chemotherapy and severe clinical results in some cases. Nucleoside analogues play an important role in preventing and reducing the risk for HBV reactivation and HBV-associated morbidity and mortality. This paper gives a systematic review of the definition, mechanism and causes of HBV reactivation and summarizes the principles and problems for antiviral treatment in patients with HBV reactivation. It is strongly recommended that all patients should be screened for HBV serum markers before chemotherapy and preventive therapy with nucleoside analogues be given in patients with HBV. The use of potent antiviral drugs with low resistance potential and close viral monitoring during therapy are important for patients with HBV infection undergoing chemotherapy.
