Hepatitis C virus caused nearly all post-transfusion hepatitis before screening. Early anti-HCV tests detected 85% of infections, with ALT and anti-HBc offering no added benefit.

Area of Science:

  • Hepatology
  • Infectious Diseases
  • Transfusion Medicine

Background:

  • Non-A, non-B hepatitis was a significant risk following blood transfusions.
  • Hepatitis C virus (HCV) was identified as the primary cause of non-A, non-B hepatitis.
  • Understanding transmission risks was crucial before widespread HCV screening implementation.

Purpose of the Study:

  • To assess the incidence of post-transfusion and postoperative non-A, non-B hepatitis in Australia.
  • To determine the role of Hepatitis C virus in transfusion-transmitted hepatitis.
  • To evaluate the efficacy of early hepatitis C testing methods.

Main Methods:

  • Retrospective analysis of blood samples from cardiac surgery patients and controls.
  • Measurement of alanine aminotransferase (ALT) levels and hepatitis B/C antibody testing.

  • Follow-up of transfusion recipients and non-transfused controls for 12 months post-surgery.

    • Main Results:

    • Post-transfusion hepatitis occurred in 1.1% of recipients receiving blood not screened for HCV.
    • Seven of eight patients with post-transfusion hepatitis seroconverted to HCV.
    • Early anti-HCV tests identified approximately 85% of infectious donations.

    Conclusions:

    • Hepatitis C virus was responsible for the vast majority of non-A, non-B post-transfusion hepatitis.
    • First-generation anti-HCV antibody tests were effective in detecting most infectious donations.
    • Surrogate markers like ALT and anti-HBc did not provide additional benefit in identifying infectious units.
