Abstract
In an attempt to accelerate marrow recovery after HLA-identical sibling bone marrow transplantation, the donors of 12 patients with haematological malignancy were given recombinant human granulocyte colony-stimulating factor (rHuG-CSF; lenograstim; Granocyte) 5 μ g/kg/day for seven doses prior to marrow harvest. All 12 recipients also received lenograstim 5 μ g/kg/day from the day of transplant until their neutrophil count was 1.0 × 109/l. In addition to lenograstim post-transplant and lenograstim-stimulated donor bone marrow the first six recipients also received donor peripheral blood stem cells that had been enriched for CD34+ stem/progenitor cells and T cell depleted on an immune absorption column (cohort 1). The second six patients (cohort 2) received lenograstim post-transplant and lenograstim-stimulated donor marrow only. All 12 patients showed a marked elevation of their circulating white blood cell count (predominantly neutrophils) on day 1 post-transplant. Compared to carefully matched historical control patients the rate of neutrophil engraftment was significantly accelerated in both patient cohorts and platelet engraftment was accelerated in cohort 2.
