Prevention of TRALI

The International Forum entitled ‘Measures to prevent TRALI’ published in Vox Sanguinis ( 92 :258–277, 2007), reports how transfusion medicine specialists diagnose and prevent transfusion-related acute lung injury (TRALI) [1]. None of the responses discussed that TRALI may be prevented by leucoreduced and washed liquid-preserved red blood cells (RBC) or by previously frozen leucoreduced, washed RBCs. Testing for antibodies against granulocytes and white blood cell (WBC) human leucocyte antigens (HLA) and reducing the length of storage of RBC at 4 ° C and platelets at 22 ° C were reported [1]. While the major concern for the blood banking community is transmission of infectious diseases, there is little concern about the severe adverse events associated with the length of storage of RBCs at 4 ° C and platelets at 22 ° C [2,3]. Basran and associates [4] reported morbidity and mortality associated with compatible RBC stored in AS-1 (ADSOL) at 4 ° C for 42 days. Red blood cells frozen with 40% w/v glycerol and stored at –80 ° C are washed after thawing to reduce the glycerol level to < 1%. Without the need to leucoreduce the RBCs by filtration prior to freezing, the previously frozen washed RBCs are leucoreduced with a total WBC number of ~1 × 10 7
