Here, we report a case of multidrug resistance in a patient with chronic hepatitis B. The patient sequentially received lamivudine, adefovir dipivoxil and entecavir, and subsequently developed single-, double- and triple-drug-resistant HBV strains. We consider this case report important because it documents, for the first time, that triple-drug-resistant HBV strains identified in a clinical set...

Objective: To compare the effectiveness and renal safety of treatment with tenofovir versus entecavir in patients with chronic hepatitis-B. Methods: Retrospective study in hepatitis-B patients who initiated treatment with tenofovir or entecavir since January 1998 until 2013. The primary effectiveness variable was defined as viral DNA < 20 UI/ml (HBV-DNA) and the variable for renal safety was va...

BACKGROUND The aim of this study was to compare the effect of combination lamivudine (LAM) and adefovir dipivoxil (ADV) versus entecavir (ETV) monotherapy for naïve HBeAg-positive chronic hepatitis B (CHB) patients. MATERIAL/METHODS Fifty enrolled patients with CHB were evenly divided into 2 groups: a group treated with of lamivudine (LAM) (100 mg/day) plus adefovir (ADV) (10 mg/day) combinat...

Seroconversion of hepatitis B virus (HBV) e-antigen (HBeAg) is a critical but often-missed therapeutic goal in standard antiviral treatments. An extreme-phenotype genome-wide association study was performed, comparing untreated spontaneous recoverers (with seroconversion of HBV surface antigen) versus entecavir-treated patients failing to achieve HBeAg seroconversion. A single-nucleotide-polymo...

hronic infection with hepatitis B virus (CHB) affects as many s 350–400 million people worldwide and 93 million people n China.1 Moreover, elderly patients with CHB are increasing. ence, the treatment of elderly patients with CHB is an imporant issue. However, to our knowledge, there is no report about he efficacy of Entecavir (ETV) treatment on elderly patients ≥60 years) with CHB. A retrospec...

BACKGROUND Serum HBV RNA is detectable during nucleoside/nucleotide analogue therapy as a result of unaffected RNA replicative intermediates or interrupted reverse transcription. We studied the predictive value of serum HBV RNA for initial virological response during nucleoside analogue therapy. METHODS Serum HBV RNA was quantified before and at 12 and 24 weeks of lamivudine or entecavir ther...

BACKGROUND To reduce the incidence of drug resistance and to maintain viral suppression, patients chronically infected with HBV might require combination therapy using two or more drugs with different resistance profiles. We investigated the activity of clevudine (CLV) in combination with other nucleoside/nucleotide analogues to determine if these combinations were compatible in vitro. METHOD...
