Abstract
Direct-acting antiviral (DAA) combinations are potent and effective drugs currently recommended for treatment of chronic HCV infection. Difficult to treat genotypes are the most important predictors of treatment failure. We report a case of DAA treatment failure in an HCV-infected patient carrying a recombinant genotype 2k/1b. This strain, first isolated from a Russian patient in 2002, has now been observed for the first time in Italy.
