Purpose Elderly patients with nonchemotherapy drug-induced agranulocytosis present commonly with severe infections, and have a mortality of at least 20%. We studied whether granulocyte colony-stimulating factor (G-CSF), a hematopoietic growth factor that shortens the duration of neutropenia, is useful in these patients. Subjects and methods We studied 54 patients ≥65 years of age who had drug-induced agranulocytosis, some of whom had been treated with G-CSF. We determined the times until hematologic recovery (defined as a neutrophil count >1.5 × 109/L), tolerance of G-CSF, and clinical outcomes. Results Of the 54 patients, 20 received G-CSF. Two patients who had not been treated with G-CSF died of uncontrolled septic shock and extensive pneumonia. The mean (± SD) time until hematologic recovery was significantly less in patients treated with G-CSF (6.6 ± 3.9 days vs. 8.8 ± 4.9 days, P <0.04). Compliance with G-CSF therapy was good; only mild flu-like symptoms and transient bone pain were reported in 12 patients. Conclusion Our findings suggest that G-CSF therapy may be beneficial in the management of drug-induced agranulocytosis in elderly patients.
