Estimated frequency:
Pruritus and urticaria were manifest in 91.9 and 83.8% of all allergic transfusion reactions (ATRs), with more severe respiratory symptoms and angioedema occurring in less than 15% of cases. Total and aeroallergen-specific IgE was higher among subjects experiencing an ATR in comparison to control subjects (median total IgE, 55.5 kU/L vs. 8.3 kU/L, p = 0.002; and median aeroallergen-specific IgE, 0.57 kUa/L vs. 0.36 kUa/L, p = 0.046). A total of 630 ATRs occurred among 1418 apheresis platelet transfusions in which a split product was given to two patients--6 cases occurred in which both recipients had an allergic reation.
