Abstract :

Introduction/Aim: Increasing evidence suggests thatseveral pathological hepatic diseases have been related to alterations of miRNAs expression.The present study was designed to assess the significance of serum miR-21, miR-223, and miR-885-5p as potential biomarkers in different clinico-pathological sequalae of HCV-related chronic liver disease. Patients and Methods: Serum miR-21, miR-223, and miR-885-5p were quantified by real-time quantitative PCR in 60 Egyptian patients with HCV-related liver disease in addition to 25 healthy controls. HCV patients were classified into: chronic HCV (n=15), liver cirrhosis (n=15), and hepatocellular carcinoma (HCC) (n=30). Results: Serum levels of miR-885-5p in cirrhotic patients (with or without HCC) were significantly higher than the noncirrhotic patients; p=0.007 and healthy control; p=0.001. However, no such significance was detected between HCV patients with and without HCC; p=0.12. Serum miRNA-885-5p was able to discriminate cirrhosis ± HCC from healthy controls using ROC analysis: AUC 0.85, 87% sensitivity and 80% specificity. As regards serum miR-21, HCC patients had significantly higher levels than non-HCC patients (non-cirrhotic and cirrhotic groups); p=0.048 and the control group; p=0.002. ROC could differentiate HCC from control group; AUC 0.89, 80% sensitivity, 80% specificity. Serum albumin and bilirubin were significantly correlated with miRNA-885-5p(r=-0.27, p=0.04) (r= 0.42, p=0.001) respectively, but such correlation was not observed with serum miRNA-21. In contrast, mi RNA 223 showed no significant difference across the studied groups. Conclusion: Along the spectrum of HCV-related chronic liver disease, miR-885-5p could be a potential marker for advanced liver damage while miR-21 could be a helpful diagnostic marker for HCC.
