hsa-miR-17-5p: A Possible Predictor of Ombitasvir/Paritaprevir/Ritonavir + Dasabuvir ± Ribavirin Therapy Efficacy in Hepatitis C Infection

Abstract

Although persistent sustained viral response rates are increased in hepatitis C infection following administration of direct-acting antiviral (DAA) agents, the pre-use predictive parameters of these antivirals and the clinical progression in patients post-treatment remain unknown. To obtain data pertaining to the predictive parameters prior to the use of ombitavir/paritaprevir/ritonavir + dasabuvir and the clinical progression in patients following antiviral treatment. The expression profiles of miR-223-3p, miR-17-5p, miR-24-3p, and TLR2 - 196 to - 174 del/ins polymorphisms from the blood/serum of 34 hepatitis C virus (HCV)-infected patients pre- and post-ombitavir/paritaprevir/ritonavir + dasabuvir treatment were determined by RT-qPCR. The expression levels of miR-17-5p (P < 0.001) and miR-24-3p (P = 0.011) were significantly downregulated post-treatment as compared with those pre-treatment; however, there was no significant difference between these two groups in terms of miR-223-3p expression. In addition, there was no significant difference in TLR2 genotype or allele distribution between pre-and post-treatment (P > 0.05); nevertheless, the TLR2 del allele was decreased post-treatment (16.2%) as compared with that pre-treatment (19.1%), although the difference was not statistically significant. Moreover, a significant difference was found between the mRNA levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), and HCV RNA pre-and post-treatment (P < 0.05). Further, miR-17-5p expression correlated with both ALT and AST mRNA levels post-treatment (P.
