Thus they could be useful predictors for responses to treatment among HCV infected patients, thereby reducing ineffective treatments.<\/jats:p><\/jats:sec><jats:sec><jats:title>Aim<\/jats:title><jats:p>The current study aimed to investigate the relation between miRNA\u201021 expression profiles, transforming growth factor \u03b2 (TGF\u2010\u03b2) serum levels and response to treatment with the new direct antiviral drugs (sofosbuvir\u2009+\u2009daclatasvir\u2009\u00b1\u2009ribavirin), among HCV infected Egyptian patients.<\/jats:p><\/jats:sec><jats:sec><jats:title>Subjects and Methods<\/jats:title><jats:p>This prospective study was conducted on 50 HCV infected patients (before and after treatment) and 20 healthy volunteers. miRNA expression profiles were determined by real\u2010time polymerase chain reaction and TGF\u2010\u03b21 serum levels were measured by using enzyme\u2010linked immunosorbent assay.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>There was a significant increase in serum albumin, platelets count and a significant decrease in liver enzymes, serum bilirubin, and prothrombin time after treatment. Significant reduction of viral load among HCV patients after receiving the treatment was reported. Concomitantly, there was an increase in the relative quantity of miRNA\u201021 (<jats:italic>P<\/jats:italic>\u2009=\u2009.001*) and serum levels of TGF\u2010\u03b21 (\n<jats:italic>P<\/jats:italic>\u2009=\u2009.337) among HCV patients after receiving treatment.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Nearly all responders to direct antiviral drugs showed increased levels of both miRNA\u201021 and TGF\u2010\u03b21. This may indicate an interplay between TGF\u2010\u03b21 and miRNA\u201021 during remission or progression of viral infection. Thus miRNA\u201021 could be used as promising serum biomarker, for assessment of antiviral treatment efficacy and improvement of fibrosis among chronically infected HCV
