Hemostatic efficacy of pathogen-inactivated vs untreated platelets: a randomized controlled trial.

Pathogen inactivation of platelet concentrates reduces the risk for blood-borne infections. However, its effect on platelet function and hemostatic efficacy of transfusion is unclear. We conducted a randomized noninferiority trial comparing the efficacy of pathogen-inactivated platelets using riboflavin and UV B illumination technology (intervention) compared with standard plasma-stored platelets (control) for the prevention of bleeding in patients with hematologic malignancies and thrombocytopenia.

The clinical impact of platelet refractoriness: correlation with bleeding and survival.

Background: Despite supportive care with platelet (PLT) transfusions, bleeding complications occur in a substantial number of patients with thrombocytopenia due to cytotoxic therapy. Moreover, refractoriness to PLT transfusions remains a frequently encountered problem. The clinical impact of PLT transfusion failure was investigated in 117 patients, part of a randomized PLT transfusion trial, which excluded patients with HLA and/or HPA alloantibodies.

A multicenter randomized study of the efficacy of transfusions with platelets stored in platelet additive solution II versus plasma.

Randomized studies testing the clinical efficacy of platelet additive solutions (PASs) for storage of platelets are scarce and often biased by patient selection. We conducted a multicenter, randomized study to investigate clinical efficacy of platelets stored in PAS II versus plasma, also including patients with clinical complications associated with increased platelet consumption. A total of 168 evaluable patients received pooled buffy coat-derived platelet concentrates (PCs) suspended in either plasma (n = 354) or PAS II (n = 411) stored up to 5 days.
