摘要：

Mutations associated with hepatitis B virus (HBV) resistance to lamivudine have not been extensively addressed in human immunodeficiency virus (HIV)-HBV coinfection. We have studied the HBV polymerase sequences from nine coinfected patients who experienced HBV recurrence while under lamivudine treatment. In seven of these nine patients, Met(550), belonging to the highly conserved YMDD motif, was mutated to Val and was associated with a substitution of Met for Leu(526) in each case. In the two remaining patients, we found a Met(550)-to-Ile change that was associated in only one case with a Leu(526)-to-Met mutation. No mutation was observed in three control patients not receiving lamivudine. This study demonstrates the emergence of particular genetic profiles in HBV-HIV-coinfected patients experiencing a loss of control of HBV infection despite high doses of lamivudine.
