Interleukin-28B polymorphisms are associated with an early viral response in patients receiving hepatitis C therapy.

ABSTRACT: Prediction of the efficacy of pegylated interferon (PEG-IFN) plus ribavirin (RBV) therapy against hepatitis C (HCV) infection is valuable for determining its applications. This study investigated the relationship between the early response of HCV to PEG-IFN/RBV therapy and the inter-leukin (IL)-28B genetic polymorphism in patients with HCV infection. The genotypes of IL-28B rs8099917 T>G single nucleotide polymorphism were determined in 144 patients with HCV infection. Among them, 59 were treated with PEG-IFN/RBV. The frequency of IL-28B TT homozygosity was 75.2% in patients with HCV serotype 1 and 84.6% in patients with serotype 2. Multivariate analysis showed that IL-28B TT homozygosity (P=0.014) and the platelets number (P=0.030) was associated with the early suppression of HCV-RNA at 1
