Detection of hepatitis C virus-specific antigens in semen from non-A, non-B hepatitis patients

Abstract

Semen samples from nine patients clinically diagnosed as having non-A, non-B hepatitis (NANBH) were tested by an ELISA using antibodies raised in rabbits against HCV-specific specific antigens. The semen from all nine patients had elevated levels of HCV-specific antigen in comparison to semen from five healthy donors. Semen from five of the nine patients had significant levels of the HCV-specific antigen. Seven of the eight serum samples from these patients were reactive with the standard C-100 HCV ELISA. Eight of these nine patients had serum reactive for HCV-specific antibodies in our ELISA using HCV-specific antigens. This more direct evidence for viral presence supports the earlier epidemiological data suggesting that HCV could be transmitted sexually.
