Abstrakt: | In Egypt, Sofosbuvir (SOF) in combination with Dataclasvir (DCV) is the broadly used DAAs with excellent therapeutic profile. This study is designed to explore the relation between IL28B/TLR4 genetic variants and each of the followings; HCC development post SOF/DCV treatment, progression to HCC in naïve patients and SOF/DCV therapy outcome. A total of 493 blood samples were collected (controls ( n = 70); HCV patients treated with SOF/DCV ( n = 252) of whom 65 patients developed HCC, 187 patients didn't develop HCC (125 responders, 62 relapsers); naïve HCV patients ( n = 171) had early ( n = 48), late liver fibrosis ( n = 21) and HCC ( n = 102)). Both SNPs were genotyped using a TaqMan 5' allelic discrimination assay. At IL28B rs12979860 SNP, the C allele was significantly correlating with the response rate more than T allele (OR 1.9, 95% CI 1.29-2.9, p = 0.004), while at TLR4 rs4986791 SNP, no association was found (OR 6.5, 95% 0.57-75.28, p = 0.09). Both SNPs couldn't detect the probability for HCC emergence after treatment. In naïve patients, the protective alleles were detected in their lowest frequency in HCC patients ( p = 0.1, for rs12979860 and, p = 0.001 for rs4986791). SOF/DCV combination improved SVR rates in HCV genotype 4a infected patients regardless of IL28B genotype, with the best rates in those lacking the T allele. (© 2019 Chongqing Medical University.
