- Abstract: Objective To investigate changes and clinical significance of serum microRNA-155(miR-155)and microRNA-205-5p(miR-205-5p)levels in patients with hepatitis C virus(HCV)infection.Methods A total of 141 patients with HCV infection were collected and divided into the HCV-1b group(92 cases)and the non HCV-1b group(49 cases)according to their genotype,and another 141 healthy volunteers who underwent physical examinations in our hospital during the same period were collected as the control group.The general information,biochemical indicators and serum levels of miR-155 and miR-205-5p were compared between the three groups.According to the grading of hepatitis activity,HCV infected patients were classified into the G0,G1,G2,G3 and G4 groups,and serum levels of miR-155 and miR-205-5p were compared between the five groups.Receiver operating characteristics(ROC)curve was used to analyze clinical values of serum miR-155 and miR-205-5p in diagnosing hepatitis activity of G1-G4 in patients with HCV infection.Results The levels of alanine aminotransferase(ALT),aspartate aminotransferase(AST)and total bilirubin(TBIL)were obviously higher in the HCV-1b group and the non HCV-1b group than those in the control group,while the level of ALB was obviously lower than that in the control group(P＜0.05).The serum level of miR-155 was increased in turn in the control group,the non-HCV-1b group and the HCV-1b group,and the serum level of miR-205-5p was decreased in turn(P＜0.05).The serum level of miR-155 increased in turn with the increased grading of hepatitis activity,while the serum miR-205-5p level decreased in turn(P＜0.05).The area under curve(AUC)values of serum miR-155,miR-205-5p and their combination in diagnosing hepatitis activity of G1-G4 in HCV infected patients were 0.855,0.793 and 0.913,respectively,and the combination of the two is superior to each individual diagnosis(P＜0.05).Conclusion The serum miR-155 level increases and miR-205-5p level decreases in HCV infected patients.The combination of the two has high efficacy in diagnosing hepatitis activity of G1-G4 in HCV infected patients.
