Glanzmann's thrombasthenia; assessment of the response to platelet transfusions.
The response to platelet transfusions was studies in two patients with Glanzmann's thrombasthenia. Antibodies to platelets were detected in one patient who had failed to respond to platelet transfusions, and bled during and after surgery despite fresh whole blood transfusions. The other patient had no detectable antiplatelet antibodies, exhibited improved platelet function when normal platelets were added to her platelet-rich plasma and experienced a favorable response to platelet transfusions during major surgery. These cases demonstrate the importance of antiplatelet antibodies as a determinant of a patient's response to platelet transfusion, the value of this therapy in qualitative platelet disorders, and the potential usefulness of in vitro studies to predict the outcome of platelet transfusions in such patients.
