Patients with hematological and oncological diseases often require intensive, supportive hematotherapy due to the underlying disease or chemo-/radiotherapy. As a consequence, they had an increased transfusion-associated risk of hepatitis C virus infections (non-A, non-B-posttransfusion hepatitis) until 1989-1990, when specific and sensitive HCV antibody tests became available. This is confirmed by our study of 'first' and 'second' generation (1.0 and 2.0) anti-HCV EIAs against structural and non-structural (NS) antigen-determinants. Ten of 101 patients (10.9%) were anti-HCV positive in 2.0 tests. HCV antibodies were detected more often by 2.0 EIAs and the new HCV-immunoblot (4-RIBA), than by 1.0 EIAs. In this respect, the patients' serological HCV profile differs from that of healthy blood donors, which display a prevalence of NS-antibodies.
