Abstract
ObjectivesWe sought to evaluate clinically a hepatitis C virus (HCV) whole-genome, next-generation sequencing (NGS) pipeline that is agnostic to viral genotype. MethodsPerformance of the NGS pipeline was assessed through comparison of results with Sanger sequencing (SS) of partial HCV genomes. ResultsThere was 98.7% (376/381) concordance for viral subtype between SS and NGS. The positive and negative per cent agreements for determination of resistance-associated substitutions were 97.8% (95% CI 92.5–99.4%) and 99.9% (95% CI 99.5–100.0%), respectively. The NGS pipeline was also able to detect novel subtypes, mixtures, recombinants, transiently occurring resistance mutations and distinguish re-infection with the same subtype from relapse. DiscussionParticular scenarios where NGS may be used include settings without universal access to pan-genotypic antiviral regimens, those infected with a ‘rare’ subtype or who have been failed by first-line therapy, and in cases of suspected re-infection.
