Evolution of entecavir-resistant hepatitis B virus during entecavir and adefovir dipivoxil combination therapy
The emergence of entecavir (ETV) resistance is rare, particularly in a longitudinal study. The aim of the present study was to characterize the evolution of ETV-resistant variants during antiviral therapy using entecavir monotherapy followed by ETV-adefovir dipivoxil (ADV) combination therapy. The study included a prospective cohort of 53 consecutive chronic hepatitis B (CHB) patients. During t...
متن کاملEvolution of hepatitis B virus during long-term therapy in patients with chronic hepatitis B.
BACKGROUND Long-term lamivudine (LAM), adefovir (ADV) and entecavir (ETV) treatment induce the emergence of drug-resistant hepatitis B virus (HBV) in patients with chronic hepatitis B infection. AIM To evaluate the LAM, ADV and ETV resistance mutations detected in our patient group. MATERIALS AND METHODS Twenty patients who had received at least two years of treatment with nucleoside/tide a...
متن کاملTruncated Hepatitis B virus like nanoparticles: A novel drug delivery platform for cancer therapy
Nowadays, Nano-sized drug delivery systems have been studied extensively for theirpotential in cancer therapy. Various drug nanocarriers are being developed including liposomes, micelles, and Virus like nanoparticles (VLNPs). VLNPs offer many advantages for developing smart drug delivery systems due to their precise and repeated structures and relatively large cargo capacities. Truncated ...
متن کاملIdentification of Drug Resistant Mutants of HBV (Hepatitis B Virus) by Direct Sequencing in Iranian Patients Treated with Lamivudine
Background and Aims: lamivudine is amongst the antiviral for drug chronic hepatitis B treatment. During therapy with lamivudine, variants may emerge with YMDD mutation in the reverse transcriptase (RT) region of polymerase gene. This mutation might have a role in drug resistant for HBV. Materials and Methods: HBV DNA extraction from serum sample of 88 patients, were subjected to nested PCR for ...
