The treatment of HBV infection in patients with HIV co-infection presents several peculiar features: some drugs active against HBV are also active against HIV. This precludes their use in monotherapy in HIV-HBV co-infected patients due to the potential risk of selecting HIV-resistant strains. Telbivudine seemed to be a candidate for exclusive anti-HBV therapy because it exerts no significant in...

conclusions both add-on ldt and switching to peg-ifn-α2a were satisfactory and optimal treatments for chb patients with poor responses to adv. both rescue strategies resulted in significant reductions in serum viral load and alt levels, and were associated with high rate of serological outcomes in our hospital. patients and methods ninety-seven chb patients with hbv dna > 2 log10 copies/ml 48 w...

BACKGROUND Here, we investigated the treatment response and evolution of HBV resistance during lamivudine (LAM) plus adefovir (ADV) and entecavir (ETV) monotherapy in patients with ADV-resistant mutants. METHODS Of the 53 patients with ADV-resistant mutants, 25 received combined LAM plus ADV therapy (LAM+ADV group) and 28 received ETV monotherapy (ETV group) for at least 12 months (median 24 ...

BACKGROUND AND AIMS Lamivudine (LAM) is still widely used for anti-HBV therapy in China. The study aimed to clarify whether a newly-found rtM204Q mutation from patients was associated with the drug resistance. METHODS HBV complete reverse-transcriptase region was screened by direct sequencing and verified by clonal sequencing. Replication-competent plasmids containing patient-derived 1.1mer m...

New optimism surrounds treatments for chronic hepatitis B (CHB). Interferon- alpha , lamivudine, and adefovir dipivoxil are currently approved by the United States Food and Drug Administration for the treatment of CHB. All 3 treatments possess unique characteristics with respect to their side effect profiles, potencies, and treatment niches within the spectrum of CHB. New agents, which are in v...

A simple and reliable stability-indicating RP-HPLC method was developed and validated for analysis of adefovir dipivoxil (ADV).The chromatographic separation was performed on a C18 column using a mixture of acetonitrile-citrate buffer (10 mM at pH 5.2) 36:64 (%v/v) as mobile phase, at a flow rate of 1.5 mL/min. Detection was carried out at 260 nm and a sharp peak was obtained for ADV at a reten...
