ABSTRACT
Objective·To investigate the prevalence of pre-existing direct-acting antiviral agents (DAAs) resistance associated variants (RAVs) in genotype 1 hepatitis C virus (HCV)/human immunodeficiency virus (HIV) co-infected patients.Methods·All NS3 and NSSB HCV sequences in genotype 1 HCV/HIV co-infected patients were retrieved from NCBI GenBank database.And sequences were aligned and analyzed using software MEGA 5.0.Results·In total,the overall prevalence of DAAs RAVs in NS3 region was high (26.06% and 38.18%,respectively),no matter in genotype 1a or genotype 1b.In genotype 1a,the high prevalence of RAVs mainly presented in the position Q80 (8.45%).In genotype lb,S122 RAV was most observed (36.36%).It is worth noting that,RAVs in NS5B region were rare observed (0.77%) in this study,especially as no RAV was detected in any sequence of genotype 1a patients.Conclusion·The prevalence of pre-existing RAVs is high in NS3 region but rare in NS5B region in HCV/HIV co-infected patients,suggesting that NS5B inhibitors based combination regions are a better choice for HCV/HIV co-infected patients.
