  • Title: [Transfusion-associated HIV infection].
    Author: Gürtler LG, Eberle J, Bader L.
    Journal: Infusionsther Transfusionsmed; 1994 Aug; 21 Suppl 1():7-10. PubMed ID: 8000258.
    Abstract:
    OBJECTIVE: Estimating the risk of HIV transmission by blood or inactivated plasma transfusion. A discussion of the methods and techniques for the diagnosis of HIV infection in blood donors. DATA SOURCES: Reports in German and English on this topic as well as own experiences of the authors. SELECTION CRITERIA: No specific selection criteria. RESULTS: Transfusion associated HIV infection may be prevented by donor selection, the very efficient anti-HIV testing, by p24-antigen testing that may detect some anti-HIV negative donations especially during the early time of seroconversion and by more recent introduced techniques like polymerase chain reaction (PCR) and signal amplification assay (SAA). PCR and SAA are under development and until now not sensitive and specific enough to contribute significantly to an earlier detection of HIV infected blood. Procedures for the inactivation of HIV in plasma or whole blood have been described. Until now use of psoralens, methylene blue or direct UV irradiation may reduce viral load but have not definitely been proven by clinical trials to be 100% efficient. CONCLUSIONS: To minimize transfusion associated HIV infection in future years reduction of total amount of transfused units, restriction to regional donor recruiting and further refinement of tests will be necessary. A 100% safety of blood transfusion for infectious agent cannot be achieved, especially considering new agents and further spread of until now geographically restricted viruses.
