Lamivudine is a potent inhibitor of hepatitis B virus (HBV) replication, but its long-term use may be associated with HBV tyrosine-methionine-aspartate-aspartate (YMDD) motif mutation. To examine the clinical features and course after emergence of YMDD mutants, 55 patients who received lamivudine th

Lamivudine is an effective antiviral agent for the treatment of chronic type B hepatitis. Recent studies have shown the appearance of lamivudine resistant viruses with mutations at the tyrosine-methionine-aspartate-aspartate (YMDD) motif of the viral polymerase in hepatitis B virus (HBV) infected pa
Treatment of hepatitis B virus (HBV) with lamivudine is effective in suppressing virus replication and results in reduced inflammatory activity. However, the emergence of lamivudine-resistant mutant virus, with amino acid substitution in the YMDD motif of DNA polymerase, has been reported. We report
## Abstract The pretherapy factors that could influence the emergence of resistant hepatitis B virus (HBV) tyrosineβmethionineβaspartateβaspartate (YMDD) motif mutants against lamivudine are not fully known in prolonged lamivudine therapy for hepatitis B e antigen (HBeAg)βpositive chronic hepatitis
