Introduction: Lamivudine is a potent inhibitor of hepatitis B virus (HBV) replication via suppression of the RNAdependent DNA polymerase. However, patients with prolonged therapy were previously detected harboring drugresistant mutants. Such mutants though partially replication defective, confer resistance to lamivudine and can elicit exacerbation of hepatonecro-inflammation. Cases presentation: In this case series, we examined mutations in the YMDD motif gene in five lamivudinetreated patients (60 yr male, 50 yr female, 46 yr male, 36 yr male and 42 yr male) and in four untreated patients (34 yr female, 29 yr male, 29 female and 37 yr male). Rare mutational patterns of rtM204L in conjunction with rtL108M were recognized conferring resistance to lamivudine. The rtL180M compensatory mutation was identified in conjunction with rtM204V/I/L; among which three patients had viral and bioche.. Read More»
