Platelet immunology and alloimmunization
Platelets express a variety of immunogenic markers on the cell surface. Some of these antigens are shared with other cell types as in the case of HLA antigens, which are shared with virtually all nucleated cells in the body, whereas others are observed to be essentially platelet specific. This chapter reviews the antigens expressed on platelets, the various patterns of alloimmunization to these...
متن کاملAlloimmunization following prophylactic granulocyte transfusion.
Nineteen noninfected adults receiving initial induction chemotherapy for acute nonlymphocytic leukemia (ANLL) were randomized to receive either prophylactic granulocyte transfusion or platelet transfusion alone on an alternate-day schedule. An average of 11 granulocyte transfusions (range 3--19) were administered/patient with a mean dose of 11.5 X 10(9) granulocytes/transfusion. The groups were...
متن کاملTransfusion and Alloimmunization in Sickle Cell Disease
In 1,814 patients with sickle cell disease who had been transfused, the overall rate of alloimmunization to erythrocyte antigens was 18.6%. The rate of alloimmunization in this group appears to be an explicit function of the number of transfusions received because it increases exponentially with increasing numbers of transfusions. Alloimmunization usually occurred with less than 15 transfusions...
متن کاملTRANSFUSION MEDICINE Universal prestorage leukoreduction in Canada decreases platelet alloimmunization and refractoriness
Randomized controlled trials have shown a reduction in platelet alloimmunization and refractoriness in patients with acute leukemia (AL) with the use of poststorage leukoreduction of blood products. Universal prestorage leukoreduction (ULR) of red cell and platelet products has been performed in Canada since August 1999. We conducted a retrospective analysis of 13 902 platelet transfusions in 6...
متن کاملLow frequency of anti-D alloimmunization following D+ platelet transfusion: the Anti-D Alloimmunization after D-incompatible Platelet Transfusions (ADAPT) study.
The reported frequency of D alloimmunization in D- recipients after transfusion of D+ platelets varies. This study was designed to determine the frequency of D alloimmunization, previously reported to be an average of 5 ± 2%. A primary anti-D immune response was defined as the detection of anti-D ≥ 28 d following the first D+ platelet transfusion. Data were collected on 485 D- recipients of D+ ...
