Abstract:
Except for post-transfusion hepatitis (PTH), the transmission of disease by blood transfusion appears to be very limited. There are only a few case reports documenting the transmission of malaria and other parasitic diseases, syphilis, or bacterial infections. The ability to eradicate PTH will depend on the development of sensitive-specific tests for the non-A, non-B agent(s). In the interim, two important steps that might be taken to reduce the incidence of PTH are the careful recruitment of blood donors and, most important, the judicious use of blood and its components.
Insights
Disease transmission via blood transfusion is rare, except for post-transfusion hepatitis (PTH). Reducing PTH requires careful donor screening and judicious blood product use while awaiting sensitive diagnostic tests.
Area of Science:
- Transfusion Medicine
- Infectious Disease Transmission
- Hepatology
Background:
- Blood transfusions are generally safe, with limited documented disease transmission.
- Post-transfusion hepatitis (PTH) remains a significant concern.
- Other transfusion-transmitted infections include malaria, parasitic diseases, syphilis, and bacterial infections.
Purpose of the Study:
- To review the risks of disease transmission through blood transfusion.
- To highlight the importance of addressing post-transfusion hepatitis (PTH).
- To suggest interim strategies for reducing PTH incidence.
Main Methods:
- Review of existing case reports and medical literature.
- Analysis of disease transmission patterns in transfusion medicine.
- Discussion of diagnostic and preventive measures for transfusion-transmitted infections.
Main Results:
- Except for PTH, disease transmission via blood transfusion is infrequent.
- Effective eradication of PTH hinges on developing sensitive and specific tests for non-A, non-B agents.
- Current strategies to mitigate PTH risk include careful donor selection and appropriate use of blood components.
Conclusions:
- Blood transfusion safety is high, with PTH being the primary exception.
- Development of diagnostic tests for non-A, non-B hepatitis agents is crucial for eradicating PTH.
- Prudent blood donor recruitment and judicious use of blood products are essential interim measures to reduce PTH incidence.
