ABSTRACT
Hepatic C virus (HCV) infection is a special case in Egypt due to its historical aspects, epidemiology, risk factors, andgenotype. Therefore, an urgent need arose to assess the HCV progression and efficacy of the used antiviral drugs. Thisstudy aimed to evaluate the role of different miRNAs types and blood dielectric measurements in the early diagnosisand prognosis of HCV in Egyptian patients. The study was carried out on a total of 80 blood samples. Twenty of theseblood samples were withdrawn from healthy volunteers and were served as the control group (G1). Sixty HCV patientsamples were divided according to the received treatment into four groups (15 for each). The second group (G2)included HCV patient samples, who did not receive any treatment. The third (G3), fourth (G4), and fifth (G5) groupsincluded the samples of HCV patients who were treated with Sovaldi (400mg) for 1, 2, and 3 months, respectively. G3,G4, and G5 were simultaneously administered Ribavirin (200 mg) and Daclatasvir (60mg) daily for 3 months. Theobtained results demonstrated the upregulation of miR-21, miR-155, and miR-205 and downregulation of miR-122and miR-133a in all HCV patients. HCV patients who did not receive any treatment showed a lower conductivity dueto the action of the virus; either the free charges on the surface of the red blood cells (RBCs) or membrane deformationor alterations were reduced. Noticeable improvement reached to nearly normal values in different miRNA expressionsand RBC dielectric relaxations was achieved by Sovaldi treatment.
