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 کاملSuccessful treatment with adefovir dipivoxil in a patient with fibrosing cholestatic hepatitis and lamivudine resistant hepatitis B virus.
Fibrosing cholestatic hepatitis (FCH) is a severe clinical and histological variant of hepatitis B virus (HBV) infection seen most commonly in the HBV infected allograft after liver transplantation. Without treatment, FCH is fatal, rapidly and universally. Remission has been reported with lamivudine but is associated with evolving resistance to lamivudine. Adefovir dipivoxil has recently been r...
متن کاملPathologic Femoral Neck Fracture Due to Fanconi Syndrome Induced by Adefovir Dipivoxil Therapy for Hepatitis B
In Fanconi syndrome, hypophosphatemic osteomalacia is caused by proximal renal tubule dysfunction which leads to impaired reabsorption of amino acids, glucose, urate, and phosphate. We present a rare case of a 43-year-old Korean male who was found to have insufficiency stress fracture of the femoral neck secondary to osteomalacia due to Fanconi syndrome. He had been receiving low-dose adefovir ...
متن کاملLong-term adefovir dipivoxil monotherapy for up to 5 years in lamivudine-resistant chronic hepatitis B.
BACKGROUND Large clinical studies assessing long-term adefovir dipivoxil salvage monotherapy in patients with lamivudine-resistant chronic hepatitis B (CHB) are lacking, particularly in patients positive for hepatitis B e antigen (HBeAg). We assessed the efficacy and resistance profile of adefovir dipivoxil monotherapy for up to 5 years in a large cohort of Korean patients with lamivudine-resis...
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 ...
