PLATELET TRANSFUSION REACTIONS

Pdf Summary

The document discusses transfusion medicine, specifically focusing on platelet transfusions and platelet refractoriness. It presents a case study of a 30-year-old woman with leukemia and discusses the expected patient response to platelet transfusion. The text highlights the importance of investigating platelet refractoriness and outlines various strategies for managing patients not responding adequately to platelet transfusions. It explains both nonimmune and immune causes of platelet refractoriness and provides insights into HLA matching, crossmatching, and other techniques to address immune-mediated platelet refractoriness. The document also emphasizes the significance of different posttransfusion platelet count measurements in diagnosing refractoriness and offers a decision algorithm for HLA-selected platelets. Additionally, it mentions the risks associated with alloimmunization and highlights the role of public matching for platelet antigens. Overall, the text aims to enhance the understanding of platelet transfusion reactions and strategies for managing platelet refractoriness in clinical practice.
