Abstract

In order to assess the clinical utility of granulocyte transfusions (GT), the stimulating effects of donor granulopoiesis for GT therapy were examined using either low dose recombinant human granulocyte colony-stimulating factor (rhG-CSF) or dexamethasone (DEX). The increment of leukocytes, polymorphonuclear cells (PMN) and monocytes in the subjects stimulated with rhG-CSF (0.7 μg/kg SC) surpassed each increment in those with DEX alone (1 mg PO). The lymphocyte counts after DEX stimulation decreased in contrast to those after G-CSF stimulation. This dose of G-CSF did not enhance the priming effects on the superoxide release from PMN. The serum levels of lysozyme, but not of lactate dehydrogenase, in G-CSF stimulated donors were higher than those in DEX-treated donors. The serum macrophage/monocyte-colony stimulating factor (M-CSF) levels in DEX stimulation were lower than in either G-CSF stimulation or no stimulation. The net yield of the PMN in GT on G-CSF stimulation was practically larger than that on DEX stimulation. One of the two patients who received GT collected by DEX stimulation died of aspergillosis. Two of the five patients who received PMN mobilized by G-CSF died of fungal infections or necrotizing fasciitis, although two of the remaining patients overcame severe bacterial infections. These results suggest that low dose G-CSF effectively and safely mobilizes a sufficient quantity of PMN from GT-donors without excessive superoxide generation from the transfused cells. This low dose G-CSF stimulation may be substituted for conventional DEX stimulation for GT. 1996 Japan Pediatric Society.
