Treatment of severe thrombocytopenia in alloimmunized, transfusion-refractory patients.
A significant proportion of patients with hematologic malignancies who are exposed to multiple transfusions will develop alloantibodies to platelet human leukocyte antigens (HLA), resulting in poor responses to subsequent platelet transfusions. Transfusion of HLA-identical platelets is an effective method of platelet support in these patients, but perfectly HLA-matched platelets are often not available. In this paper, we review the recent literature on platelet transfusion support in alloimmunized individuals and illustrate alternative management strategies with cases from our own practice.
