Abstract

Background/Aims: Despite limited evidence for efficacy, granulocyte transfusions (GTX) are used to prevent and treat opportunistic infections in patients with neutropenia. Methods: Three hundred and seventy-three GTX given to 74 patients were assessed retrospectively. Results: GTX were discontinued because of clinical improvement more often in patients with severe infections than in patients without severe infections (27 vs. 12%; p ≤ 0.002), whereas deaths resulted in discontinuation of GTX therapy less often in patients with severe infections than without (8 vs. 39%; p ≤ 0.002). Patients who died by 12 weeks after GTX initiation were more likely to have leukemia (p = 0.03), not to have recovery of neutrophil counts (p < 0.0001), and to have started GTX during a critical care unit stay (p < 0.001). Uses of granulocyte colony-stimulating factor (p ≤ 0.02) and interferon-γ (p ≤ 0.04) were more common in patients who survived. In patients with comorbidities (31%; odds ratio, OR, 12.6; 95% confidence interval, CI, 2.4-65.7; p ≤ 0.003), GTX was started in the critical care unit (OR 8.8; 95% CI 2.5-30.9; p < 0.001), and a high total bilirubin level at the end of GTX (OR 2.1; 95% CI 1.1-4.2; p = 0.03) had a higher probability of death 12 weeks after GTX therapy commenced. Conclusions: The possibility that a niche population may benefit from GTX requires further assessment.
