Higher safety in platelet transfusions using Intercept Blood System

Beydogan, Zelal January 2007 (has links)
<p>Background. Platelets (thrombocytes) are the smallest cells in the blood. Platelet fulfils functions as formation of blood clots when bleeding. Low levels leads to bleeding while high levels increase the risk of thrombosis (obstruction of the circulatory flow system). Platelet transfusions may be required for patients with systemic bleeding and for patients at higher risk of bleeding because of coagulation defects, sepsis (presence of bacteria in the bloodstream), or platelet dysfunction related to medication or disease. A pathogen-reduction system for platelet components would be a useful method since it reduces the risk of bacterial, protozoa, viral and white blood cell contamination. The Intercept Blood System method (IBS) for platelets, destroys DNA and RNA and was validated against the routine method in order to reduce pathogen transmission risk during transfusion. The validation of IBS, the trombocyte count for100 buffy coat concentrates from 2007 were compared to values for 100 buffy coat concentrates from 2006 that had been treated with gamma-radiation. Akademiska sjukhuset in Uppsala has a requirement that 75% of the platelet concentrates contain at least 300*10 9 platelets per unit. IBS fulfilled to 94% compared to 98% for the routine method.</p><p>Thus, the IBS-method was well above the required value and is now used at</p><p>Akademiska sjukhuset in Uppsala.</p>
