Effects of GB virus-C/hepatitis G virus on hepatitis B and C viremia in multiple hepatitis virus infections

Abstract

We found that patients with dual HBV and GBV-C/HGV infection had comparable serum HBV DNA positivity and mean virus concentration compared with age-matched HBV carriers, and those with triple infection had a significantly lower HBV DNA positivity. Serum HCV RNA positivity and mean virus titer were similar between HCV carriers with or without GBV-C/HGV co-infection, and those with GBV-C/HGV co-infection seemed to have a lower serum ALT level. These data suggest that GBV-C/HGV infection exerts no significant suppression on levels of chronic hepatitis B or hepatitis C viremia.
