The effects of rhG-CSF administration on fMLP-induced neutrophil CD11b and CD18 upregulation were studied in nine patients suffering from intermediate and high grade non-Hodgkin's lymphomas. Blood samples were obtained before recombinant human granulocyte colony-stimulating factor (rhG-CSF) administration and 24 hrs after rhGSF interruption. The growth factor was administered subcutaneously for five days in a dosage of 5 microg/Kg/day. Nine normal subjects were studied as controls. Five patients showed an impaired baseline CD11b and CD18 upregulation, which was corrected by rhG-CSF therapy. Four patients showed a normal baseline CD11b and CD18 upregulation, but this function was reduced by rhG-CSF therapy. All patients showed a normal baseline fMLP-induced luminol-enhanced chemiluminiscence and significantly increased chemiluminescence values after rhG-CSF administration. We conclude that, while in some patients rhg-CSF is able to improve neutrophil CD11b and CD18 upregulation in response to chemotactic agents, in other patients a decrease of this function can occur, maybe due to a relative immaturity of the circulating neutrophils induced by rhG-CSF.
