| Popis: | AIM: To investigate the predictability of interleukin-28B single nucleotide polymorphism rs12979860 with respect to sustained virological response (SVR) in chronically hepatitis C virus (HCV) genotype-1 patients treated with a protease-inhibitor and pegylated interferon-$\alpha$ (Peg-INF-$\alpha$) based triple-therapy. METHODS: We searched PubMed, the Cochrane Library and Web of Knowledge for studies regarding the interleukin 28B (IL-28B)-genotype and protease-inhibitor based triple-therapy. Ten studies with 2707 patients were included into this meta-analysis. We used regression methods in order to investigate determinants of SVR. RESULTS: IL-28B-CC-genotype patients achieved higher SVR rates (odds 5.34, CI: 3.81-7.49) than IL-28B-non-CC-genotype patients (1.88, CI: 1.43-2.48) receiving triple-therapy. The line of therapy (treatment-na\"ive or -experienced for Peg-INF-$\alpha$) did not affect the predictive value of IL-28B (p=0.1). IL-28B-CC-genotype patients treated with protease inhibitor-based triple-therapy consisting of Boceprevir, Simeprevir, Telaprevir or Vaniprevir showed odds of 1.86, 9.77, 4.51 and 0.89, respectively. The odds for CC genotype patients treated with Faldaprevir cannot be quantified, as only a single study with a 100% SVR rate was available. CONCLUSION: IL-28B-SNP predicts the outcome for chronic HCV genotype-1 patients receiving protease inhibitor-based triple-therapy. The predictive value varies between the different protease inhibitors. Comment: 21 pages, 3 figures, 1 table |
