Protocol for the Infusion of Buffy Coat-derived Cryopreserved Platelets in Patients With Severe Thrombocytopenia

Summary

The increasing need for blood components and the increasingly careful donor selection procedures, make the availability of blood components very reduced, in particular for platelets that are currently administered preferably "fresh" or cryopreserved, only in emergency conditions. Exceeding this limit through the spread of use of cryopreserved platelets in the common clinical practice, might help clinicians to avoid wasting valuable products and face periods of particular shortage of donors Some studies already published in the literature over the last decade (1,2) have demonstrated the safety and efficacy of autologous cryopreserved platelets . The main objective of the proposed study is to evaluate the efficacy and safety of platelets, cryopreserved with DMSO using a a new method, in patients with severe thrombocytopenia. This is the in vivo phase of a study where availability and efficacy of cryopreserved platelets has been assessed in vitro.
