[Hepatitis C antibodies in non-A, non-B hepatitis patients and members of HIV risk groups (pilot study)]

In a multi-center study sera from NANB-hepatitis (NANBH) patients and members of so-called HIV-risk groups (homosexuals, i.v.-drug abusers, hemophiliacs) were investigated by the recombinant-based HCV-antibody EIA, 74.4% of chronic NANBH-patients and 20% of acute NANBH patients were anti-HCV reactive, 33.3% of HIV-1-positive homosexuals, 43.5% of i.v.-drug abusers and 73.5% of hemophiliacs. The true prevalence of infection remains to be determined by a second, independent (confirmatory) test.
