Circulating levels of collagen III and MMP-1 in patients with chronic hepatitis C co-infected with hepatitis B virus
2017
AbstractBackground: There is controversial data in the literature about the characteristics and features of dual hepatitis B and hepatitis C infection. This work is concerned with estimating the extent to which HBV could influence circulating levels of hepatitis C viral nonstructural-4 (HCV-NS4) in addition to some direct fibrosis markers in chronic hepatitis C.Methods: Thirty-eight HCV mono-infected and 87 HCV/HBV co-infected patients constituted this study. Western-blot and ELISA were used for identifying HCV-NS4, hepatitis B surface antigen (HBsAg), collagen III and matrixmetalloproteinase-1 (MMP-1) in patients’ sera.Results: Hepatitis B surface antigen (HBsAg) provided area under curve (AUC) of 0.97 for identifying HBV-patients with 89% sensitivity and 94% specificity, while HCV-NS4 antigen provided an AUC of 0.95 for identifying HCV-patients with 89% sensitivity and absolute specificity (100%). In general, patients with significant fibrosis (F2–F4) showed significantly higher concentration of collage...
