“…17 Recent studies of therapeutic granulocyte transfusions for neutropenic infections in patients with leukemia and/or undergoing HSCT have shown survival rates of 31-81%; in patients with invasive fungal infections, the survival rates range from 20-80%. These studies, summarized in Table 4, [1][2][3][4][5][6][18][19][20][21][22][23][24][25] vary in the definition of invasive fungal infections, the timing of initiating granulocyte therapy, the cell dose of granulocytes transfused, and the number of granulocyte doses given. One study was randomized, but only 60% of patients were actually neutropenic prior to receiving granulocytes, and 44% of patients randomized to the granulocyte arm received only one or two transfusions before neutrophil recovery.…”
