[Evaluation of the antiviral therapy for chronic hepatitis C in patients unresponsive to previous treatment with regard to the interleukin-28B genotypes].

The identification of the single nucleotide polymorphisms (SNP) at rs8099917 and rs12979860 loci of IL-28B gene is presently necessary for patients with the genotype HCV-1 to predict sustained viral response (SVR) in case of combined antiviral therapy with interferon and ribavirin. In addition to the implementation of the antiviral activity of IFN-α, interleukin-1β (IL-1β) and interferon-gamma (IFN-γ) are involved. The goal of this work was to evaluate the efficacy of the HCV therapy with cytokines in patients unresponsive to previous therapy with unfavorable genotypes of IL-28B gene.
