摘要

Spontaneously occurring resistance may impair the success of protease inhibitors based regimens in HCV treatment. This study aimed to evaluate associations between amino acid substitutions in NS3/NS4A domain and clinical features of 247 HCV mono or HCV/HIV co-infected patients. Fourteen samples (5.7%) harbored at least one resistance-associated substitution (RAS). The following RASs were detected in NS3 region: T54S (6-2.4%), V55A (7-2.8%), and Q80R (2-0.8%). S122G occurred in 86.9% of HCV genotype 1b samples with either natural polymorphisms or RASs. Advanced liver fibrosis and HIV co-infection were not related to NS3/NS4A amino acid substitutions.
