title: [Virus inactivated plasma].
abstract: Two different virus inactivated plasma preparations are available in Germany. Methylene blue ephotoxidized (MB) plasma is plasma from a single donation, which is photoxidized using 1 microM methylene blue and visible light (1 hour 60,000 Lux). Photochemical inactivation reduces HIV by at least 5 log10, but also fibrinogen is altered. To date, the clinical significance of this finding is still unclear, since prospective clinical studies are lacking. Solvent detergent (SD) plasma is manufactured from a pool of about 2000 plasma donations, and triton-X-100 and tri-n-butyl-phosphate (TNBP) are added for virus inactivation. HIV and hepatitis viruses are thus reduced by 5 to 6 log10. SD treatment reduces protein S and alpha-2-antiplasmin by about 40%. Clinical studies have already demonstrated, that SD plasma is comparable with untreated, native fresh frozen plasma in terms of efficacy.
