Abstract

To evaluate viral interference between hepatitis B and C, we studied coinfected patients serologically and molecular biologically. Twenty-seven patients positive for hepatitis B surface antigen (HBsAg) and anti-hepatitis C virus (HCV) antibody, were classified into Groups BC-L and BC-H according to DNA-polymerase activity (less or greater than 100 cpm, respectively). Patients with hepatitis B or C alone were also enrolled as controls. HCV-RNA was detected more often in Group BC-L than in Group BC-H. Genotype 1b of HCV was determined in 75% of Group BC-H, 87.5% of Group BC-L, and 70.7% of hepatitis C-only patients. Activity of DNA-polymerase in coinfected patients was lower in patients positive for HCV-RNA as compared with those negative. HBsAg titers tended to be lower in coinfected patients than in patients with hepatitis B virus (HBV) alone. In conclusion, in coinfection, HBV may suppress the replication of HCV and HCV appears to reduce the expression of HBsAg and probably suppresses HBV replication.</P>
