Among 612 patients with chronic hepatitis type B, 24 patients tested positive for anti-C-100 antibody. Clinical features and viral markers of these 24 patients were studied. Anti-C-100 antibody was detected more often in patients negative for HBe antigen than those positive for this antigen (22/385 vs. 2/227 [P less than 0.01]). HCV RNA, as detected by reverse transcription and nested polymerase chain reaction, was positive in 20 of 22 patients negative for HBe antigen whereas it was detected in only one of two patients positive for HBe antigen. In a patient who seroconverted from HBe antigen to anti-HBe HCV RNA was undetectable in the HBe antigen positive phase and had become detectable after seroconversion. These data indicate that both hepatitis virus (type B and type C) can co-infect in a patient and that type C becomes active after the seroconversion from HBe antigen to anti-HBe.

D006514 Hepatitis B Surface Antigens Those hepatitis B antigens found on the surface of the Dane particle and on the 20 nm spherical and tubular particles. Several subspecificities of the surface antigen are known. These were formerly called the Australia antigen. Australia Antigen,HBsAg,Hepatitis B Surface Antigen,Antigen, Australia
D006526 Hepatitis C INFLAMMATION of the LIVER in humans caused by HEPATITIS C VIRUS, a single-stranded RNA virus. Its incubation period is 30-90 days. Hepatitis C is transmitted primarily by contaminated blood parenterally and is often associated with transfusion and intravenous drug abuse. However, in a significant number of cases, the source of hepatitis C infection is unknown.
