What is the context? To transition into an activated state, platelets require a highly efficient source of energy that is met through the production of ATP this is referred to as "platelet bioenergetics"Platelets can be removed from healthy donors and used to make platelet concentrates for clinical usePlatelet concentrates are used clinically either therapeutically (to halt bleeding) or prophylactically (to prevent bleeding in patients with low platelet counts)They are stored at room temperature (2024oC) with constant gentle agitation, in packs that allow gas exchange and have a 7-day shelf life in some jurisdictionsStoring platelets in the cold (26oC) has historically been shown to improve their ability to halt bleedingWhat is new? There is a renewed interest in cold stored platelets for use in actively bleeding patientsThere are benefits to cold-storing platelets over room temperature storageCold stored platelets are licensed in the US and Norway for certain indications for 14 daysWhat is next? Cold stored platelets have the potential to improve logistics of clinical supply of platelets, enable supply of platelet concentrates where access is currently limited, such as pre-hospital care and on the battlefield and provide improved hemostatic effects for bleeding patients.New research measuring the bioenergetic profiles of cold stored platelets could advance understanding of metabolism in cold stored platelets and support decisions on their re-introduction on a wider scale.
