Background And Aims: Chronic hepatitis B is an important health problem worldwide. Lamivudine, adefovir, entecavir and telbivudine are the oral drugs licensed for the treatment of patients with chronic hepatitis B. Implementation of antiviral therapy leads to the emergence of mutant strains during the treatment in chronic hepatitis B.

Approved hepatitis B virus (HBV) therapies include interferon-alpha and nucleos(t)ide analogues. Lamivudine (LVD) is a nucleoside analogue and following long term LVD therapy, resistance emerges in a significant number of patients. Entecavir (ETV) is a novel deoxyguanosine analogue with potent activity against HBV in chronically infected patients.

Background: Long-term antiviral therapy, although effective for treatment of hepatitis B, might select the emergence of drug-resistant hepatitis B virus (HBV) mutants. Detection of HBV mutants and determination of viral titre are two crucial parameters for monitoring treatment response and occurrence of mutants. In this study, we take lamivudine resistance as an example to develop a method that can determine both parameters in a single-tube PCR reaction.

Hepatitis B virus (HBV) with primary antiviral resistance may be rarely encountered. In this report, a chronic hepatitis B case who had never received adefovir dipivoxil but had primary adefovir resistance, was presented.
