摘要：

An increasing number of new hepatitis C virus NS3-protease inhibitors are being evaluated for the treatment of chronic hepatitis C. Treatment-induced selection of mutants conferring resistance to protease inhibitors has been shown both in vivo and in vitro. A specific mutation, A156T has been shown to confer high-level resistance to several such agents (BILN2061, VX-950, SCH446211 (SCH6) and SCH503034). Here we report the presence of the A156T mutation in close to 1% of NS3 sequences within the liver quasispecies of a chronic hepatitis C patient never treated with anti-NS3-protease inhibitors.
