BACKGROUND: 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 collagen III (P = 0.009) and lower concentrations of MMP-1 (P = 0.007) when compared to patients with minimal fibrosis (F1). However, HCV/HBV co-infected patients with F1 and F2-F4 did not show any significant difference (P > 0.05) from HCV mono-infected patients with respect to HCV-NS4, collagen III and MMP-1. These results indicate that HBV does not influence the rate of HCV-NS4 synthesis and the deposition of extracellular matrix in HCV/HBV co-infected patients and subsequently does not affect the progression rates of hepatic fibrosis.
CONCLUSION: HCV/HBV co-infected and HCV- mono-infected patients had similar clinical characteristics and there is no effect of HBV co-infection on the progression rates of liver fibrosis in chronic hepatitis C patients.
