Abstract
OBJECTIVES: The aim of the study was to identify and characterize hepatitis B virus (HBV) polymerase gene mutations associated with ongoing HBV replication in HIV/HBV-coinfected individuals receiving tenofovir (TDF). METHODS: This retrospective cross-sectional study identified 28 HIV/HBV-coinfected individuals who had received TDF for at least 3 months. All patients had samples available while receiving TDF (on-TDF), and 24 also had samples available prior to treatment (pre-TDF). Case records were reviewed to obtain clinical and virological data at the times of sampling (+/-3 months). The HBV DNA of all samples was amplified using polymerase chain reaction (PCR), and the polymerase region of..
