Bacterial contamination of platelet concentrates: pathogen detection and inactivation methods
Whereas the reduction of transfusion related viral transmission has been a priority during the last decade, bacterial infection transmitted by transfusion still remains associated to a high morbidity and mortality, and constitutes the most frequent infectious risk of transfusion. This problem especially concerns platelet concentrates because of their favorable bacterial growth conditions. This ...
متن کاملBacterial contamination of platelet concentrates stored at 20 ° C
In a series of important studies Murphy and his colleagues demonstrated that the preparation and storage of platelet-rich plasma and platelet concentrates at 22°C rather than 4°C improved their life span in vivo (Murphy and Gardner, 1969; Murphy, Sayar, and Gardner, 1970). The potential clinical relevance of this finding has been confirmed by Handin and Valeri (1971), and it is likely that this...
متن کاملRapid detection of bacterial contamination of platelet-rich plasma-derived platelet concentrates using flow cytometry.
Flow cytometry can be used to detect bacterial contamination of platelet products. In this study, we investigated whether the incubation of a minimal volume of platelet-rich plasma (PRP)-derived platelet concentrates (PCs) with growth medium improved the analytical sensitivity of flow cytometry. Five bacterial strains (Staphylococcus aureus, Staphylococcus epidermidis, Bacillus cereus, Klebsiel...
متن کاملAn Overview on Platelet-derived Microparticles in Platelet Concentrates: blood collection, method preparation and storage
Preparations of platelet concentrates (PCs) that are stored under blood bank conditions and used for transfusion purposes, appear to be enriched in platelet derived-microparticles (PMPs) with high coagulant activity that may change platelet efficacy and safety issues. High shear stress could cause shedding of PMPs from the platelet plasma membrane, platelet aggregation, and activation of the co...
متن کاملEffect of new plastics and leucocyte contamination on in vitro storage of platelet concentrates.
Platelet concentrates were prepared for in vitro storage in either Fenwal PL-732 or Cutter CLX platelet packs. The units were stored at 22 degrees C for seven days with either horizontal or tumbler agitation. Measurement of pH, hypotonic shock response and serotonin uptake indicated in vitro viability was well maintained during 5-7 days storage using either type of pack with either mode of agit...
