N2 - Granulocyte macrophage colony-stimulating factor (GM-CSF) has been shown to inhibit the chemotaxis and enhance the oxidative burst response of human neutrophils in vitro. The present study describes the effect of recombinant GM-CSF on the neutrophil and monocyte function in patients with lymphoma undergoing GM-CSF treatment. Patients with either Hodgkin's or non-Hodgkin's lymphoma were treated with various dosages (2-16 micrograms kg-1 body weight per day for 5 days) of rhGM-CSF by intravenous or subcutaneous route. Prior to and on day 5 of rhGM-CSF treatment, neutrophil and monocyte chemotaxis and chemiluminescence responses to f-Met-Leu-Phe, zymosan activated serum (ZAS) and opsonized zymosan (OZ) were determined. It was observed that chemotactic response of neutrophils to f-Met-Leu-Phe and ZAS was reduced, whereas the chemiluminescence response of both cell types to f-Met-Leu-Phe and zymosan was enhanced by up to 43-fold. rhGM-CSF treatment did not affect degranulation of the neutrophils as measured by release of vitamin B12 binding protein. Degree of modulation of neutrophil and monocyte function by rhGM-CSF was independent of rhGM-CSF dosages administered. These data suggest that phagocytic defence system may be enhanced by GM-CSF treatment and that this cytokine may be a useful therapeutic adjunct in compromised patients.
