Granulocyte transfusions for neutropenic patients with life‐threatening infections: a single centre experience in 47 patients, who received 348 granulocyte transfusions

INTRODUCTION: The role of granulocyte transfusions (GT) in patients with neutropenia-related infections remains controversial. MATERIALS AND METHODS: A retrospective analysis of 47 neutropenic patients, treated with 348 consecutive GTs for life-threatening infections between 1999 and 2004, is presented. RESULTS: The only grade III-IV toxicity observed in GT recipients was respiratory deterioration (n = 6, 12.8%). The overall infection-related mortality (IRM) approached 38%. Achievement of a neutrophil count of > 700 cells per microl after at least 50% of days of GTs (n = 33, 70%) significantly correlated with reduced IRM (27.3% vs. 64.3%, P < 0.02). GT doses of > 2 x 10(10) neutrophils per bag appeared to increase both neutophil and platelet counts following transfusion. CONCLUSION: GTs are safe and should be considered for patients with life-threatening neutropenic infections. However, prospective randomized studies of GTs are the only way to establish the true role of GTs.
