BACKGROUND: ABO compatibility can affect platelet transfusion safety and efficacy, and ABO-incompatible (ABOi) platelets likely increases the risks of transfusion reactions though the magnitude of this risk is unclear.
STUDY DESIGN AND METHODS: Data collected on all platelet transfusions administered over 36+ months were classified based on patient and product ABO blood group type and merged with a data set that included all transfusion reactions reported during that period. The transfusion reaction rates among various subsets was calculated.
RESULTS: In patients greater than 1 year of age, the transfusion reaction rate in the ABO-compatible (ABO-identical) platelet group was 1.0%, while the ABOi platelet group had an elevated reaction rate of 1.7%. The increased reaction rate for ABOi platelets held true even if the analysis were limited to Centers for Disease Control and Prevention/National Healthcare Safety Network qualifying reactions or just allergic or febrile nonhemolytic reactions. The increased reaction rate with ABOi platelets was independent of unit age. Surprisingly, major-incompatible transfusions (A/B antigen incompatible) had the highest rate of reactions, at 2.0%. During the study period, three acute hemolytic reactions were reported out of 2522 plasma-incompatible platelet transfusions (0.12%).
CONCLUSIONS: Our results find that compatible platelet transfusions have the lowest rate of transfusion reactions. While hemolytic reactions were observed with plasma-incompatible transfusions, the rate was low. Transfusion of ABO antigen-incompatible platelets had the highest rate of transfusion reactions and resulted in a transfusion reaction rate 1.5 to 2 times that of ABO compatible transfusions.
