[Possibilities of virus inactivation of pooled fresh plasma with tri-n-butylphosphate (TNBP) detergents (SD procedure)].
Treatment with tri-n-butyl-phosphate and detergent (SD-treatment) leads to efficient inactivation of viruses having a lipid enveloped surface, like hepatitis B virus, hepatitis C virus and human immunodeficiency virus, that are presently the most transfusion relevant viruses in Germany. Other lipid enveloped viruses of the herpes group like cytomegalovirus and Epstein-Barr virus are inactivated as well. Non-enveloped viruses like parvovirus B19 and picornaviruses are not inactivated by SD-treatment. Future inactivation of blood components like plasma and blood products will be a combination of SD- and heat-treatment. Keeping single plasma units in quarantine for 6 months is one of the alternatives in elevating transfusion safety. For transfused blood the safety against infectious agent will continue to depend on the effectiveness of donor selection and the efficacy of testing.
