Popis: Granulocytes may be procured either as apheresis granulocyte concentrate (AGC) or as a pooled buffy coat granulocytes (PBCG) derived from whole blood donations. The chronic myelomonocytic leukemia patient with active pneumocystis pneumonia infection, received two transfusions of AGC and PBCG each, for prolonged severe neutropenia. AGCs had a higher mean white blood cells count per bag (1.63 × 1010 vs. 1.53 × 1010), neutrophil count per bag (1.05 × 1010 vs. 0.76 × 1010), and mean neutrophils percentage (62.45% vs. 49.25%), whereas PBCGs had a higher mean red blood cells volume per bag (196.1 vs. 62.5 ml) and platelet counts (5.03 × 1011 vs. 3.6 × 1011). The rise in patients' absolute neutrophil count was comparable with both AGC and PBCG transfusions. Granulocyte transfusions helped in the management of an acute neutropenic crisis. Whole blood-derived PBCGs may be a viable alternative in to AGCs. PBCGs have a lot of logistic issues and each blood center should have its standard operating procedure.
