Cryopreserved platelets: from in vitro thrombin generation potential to in vivo safety
2015
Abstract Background: Cryopreservation of platelets (PLTs) at -80°C with dimethyl sulfoxide (DMSO) can extend their shelf life up to 2 years. Cryopreserved PLTs (CRY-PLTs) are reported to have a greater in vivo hemostatic effect than liquid-stored PLTs. Aims of this study were: i. to evaluate the thrombin generation potential of buffy coat derived cryopreserved PLTs (CRY- BC PLT) in comparison with fresh buffy coat derived platelets concentrates; ii. to determine the efficacy and safety of CRY-PLTs transfusion in hematological patients with severe thrombocytopenia. Materials and methods: BC PLTs were obtained from 5 buffy coats and pooled. The final PLTs concentrates were leukoreduced by fil…
Functional In Vitro Studies Of Buffy Coat Pooled Platelets Cryopreserved In Dimethyl-Sulphoxide With a New System
2013
Abstract Introduction Cryopreservation for long term storage of platelets (PLTs) represents a clinical useful method for avoiding platelet shortage. Many studies have tried to define, in vitro and in vivo, the entity and weight of storage-related PLTs lesions with discordant results related to different methods. We have performed an in vitro prospective study to evaluate PLTs count, viability and function of buffy coat derived pooled platelet concentrates (BC-PLTs) treated with dimethyl-sulphoxide (DMSO) and cryopreserved at -80°C with an innovative patented system not requiring laminal flow hoods and external manipulations. Materials and methods Each BC-PLTs was obtained from 5 buffy coats…
