Abstract
Fifteen patients with prolonged neutropenia (a median of 23 days with granulocyte [PMN] ≤ 500/μl) and established fungal infections that had not responded to adequate antifungal therapy were transfused with PMN concentrates collected from 35 cytokine-primed granulocyte colony-stimulating factor (GCSF) donors. Patients received a median of six transfusions. Leukocytosis and granulocytosis were observed within 24 hours of the first GCSF injection, which yielded concentrates averaging 55 × 109 white blood cells and 41 × 109 PMN. Data analysis suggested that response might be related to the duration of neutropenia and known infection, as patients given PMN tx earlier in the infectious course tended to have a better response. No significant toxicity was observed in donors.
