    Abstract:
    Colony-stimulating factors (CSF) are being increasingly used to accelerate hematopoietic recovery after bone marrow transplantation. To study the endogenous serum levels of CSF in bone marrow transplanted patients we have used immunoassays measuring granulocyte-macrophage colony-stimulating factor (GM-CSF) with a sensitivity of 0.10 ng/ml and granulocyte colony-stimulating factor (G-CSF) with a sensitivity of 0.05 ng/ml. Serum samples, taken from the conditioning treatment until engraftment, were analysed in 13 patients receiving allogeneic transplants and in eight patients receiving autologous transplants. Ten patients had acute myeloid leukemia, seven acute lymphoblastic leukemia, one acute undifferentiated leukemia, two non-Hodgkin's lymphoma and one multiple myeloma. Samples were taken 1-2 times before transplantation and 1-2 times per week after transplantation (median of 46 days in allotransplant recipients and 32 days in autotransplant recipients); 17% of the allogeneic transplanted patients and 35% of the autologous transplanted patients had detectable levels of G-CSF. In both types of transplantation the G-CSF concentrations were low: median 0.06 (range 0.05-0.14) and 0.08 (range 0.05-0.40) ng/ml respectively. GM-CSF was detected only in one analysed sample in all patients. There was no evidence of increased CSF levels related to engraftment or documented infections.
