Transfusion-transmitted hepatitis (TTH) risks from hepatitis B (HBV) and hepatitis C (HCV) are now very low. Healthcare providers should investigate other hepatitis sources in post-transfusion cases.

Area of Science:

  • Hepatology
  • Transfusion Medicine
  • Virology

Background:

  • Post-transfusion hepatitis can be transfusion-transmitted or transfusion-associated.
  • Hepatitis B virus (HBV) and hepatitis C virus (HCV) are primary causes of transfusion-transmitted hepatitis (TTH).
  • Residual TTH from other agents is extremely rare.

Purpose of the Study:

  • To assess the current risks of HBV and HCV transmission via blood transfusions.
  • To provide guidance on investigating hepatitis in transfusion recipients.

Main Methods:

  • Analysis of transfusion-transmitted hepatitis (TTH) data.
  • Risk assessment for HBV and HCV transmission using volunteer blood donors.
  • Evaluation of screening, assays, and donor selection criteria.

Main Results:

  • The risk of HBV transmission is approximately 1 in 63,000 units.
  • The risk of HCV transmission is approximately 1 in 125,000 units.
  • Current TTH risks are extremely low, necessitating investigation of alternative infection sources.

Conclusions:

  • Post-transfusion hepatitis cases should prompt investigation for non-transfusion-related causes.
  • Continued efforts to minimize HBV and HCV transmission are crucial.
  • Strategies include judicious transfusion practices, alternative therapies, advanced assays, and microbial inactivation.
