title: Granulocyte transfusion kinetics measured by chemiluminescence, nitroblue tetrazolium reduction, and recovery of indium-111-labeled granulocytes.
abstract: A 20-year-old man with chronic granulomatous disease (CGD) and who was receiving granulocyte transfusions for a refractory liver abscess was studied to compare the kinetics of 111In-labeled granulocytes with those of two functional granulocyte assays, nitroblue tetrazolium reduction and chemiluminescence. Transfused granulocytes were eliminated in both rapid and slow phases. Peak recovery was noted in the first sample, which was obtained 10 minutes after transfusion for each assay. The elimination kinetics were similar over 24 hours. These results confirm the value of using 111In-labeled granulocytes as a marker of transfused granulocytes. These data also confirm that the oxidative metabolic function of granulocytes prepared by continuous-flow leukapheresis remains intact while in the recipient's circulation. The response of the patient adds support for the use of granulocyte transfusions in certain patients with CGD.
