Method: For example, using direct sequencing of samples from treatment-naive patients from the United States, Nguyen et al demonstrated that only four (0.9%) of 472 patients were infected with viruses with primary and secondary mutations (rtA181A/S, rtA194S, and rtM250I).
Clinical course and predictive factors of virological response in long-term lamivudine plus adefovir dipivoxil combination therapy for lamivudine-resistant chronic hepatitis B patients.
Abstract: Breakthrough hepatitis occurred in three patients without complete viral response and with poor response to the preceding LAM monotherapy, and rtA181A/V substitution was detected in one of the three patients.
