We have previously shown that total T cells derived from lymph nodes (LN) involved by Hodgkin's disease (HD) secrete higher levels of colony-stimulating activity than total T cells present within benign hyperplastic (BH) LN and B-non-Hodgkin's lymphoma (B-NHL) LN, suggesting that T cells with particular properties accumulate in HD LN. To further characterize this T-cell population, we have quantified production of both granulocyte-macrophage colony-stimulating factor (GM-CSF) and macrophage colony-stimulating factor (M-CSF) production in a total of 98 T-cell clones (TCC) derived from CD25+ activated T cells present in HD LN; TCC derived from CD25+ T cells obtained from B-NHL LN(101 TCC), BH LN(95 TCC), and peripheral blood (PBL; 38 TCC) of healthy donors were used as controls. HD LN were characterized by the presence of an elevated number (44%) of TCC producing particularly high titers of both GM-CSF and M-CSF, whereas only a minority of such TCC was found in control groups (10% in B-NHL, 16% in BH, 8% in PBL). These observations support the hypothesis of a selection of T-cell families with particular properties occurring in contact with Reed-Sternberg (RS) cells. According to the biological properties of GM-CSF and M-CSF, it seems reasonable to suggest the involvement of this particular subset of T cells in the granulomatous process, the peripheral blood polynucleosis, and in the paracrine growth of RS cells.

The difference between the effects of administration of recombinant human granulocyte colony-stimulating factor (rhG-CSF) and recombinant human granulocyte-macrophage colony-stimulating factor (rhGM-CSF) was studied in 39 children with neutropenia secondary to chemotherapy (absolute neutrophil count (ANC) less than 1,500/microliters. The children were divided into two groups. The first group (G-CSF) included 25 children (12 with acute lymphoblastic leukemia [ALL]-non-Hodgkin's lymphoma [NHL] and 13 with solid tumors) and the second group (GM-CSF) included 14 children (5 with ALL-NHL and 9 with solid tumors). All 39 children received of either G-CSF or GM-CSF (5 micrograms/kg/day) subcutaneously at the end of each chemotherapy course for a maximum duration of 14 days. The effect of G-CSF and GM-CSF on the ANC, the antibiotic therapy administration, and the length of hospital stay were studied for both groups at two cycles of chemotherapy. During both cycles a faster rise of ANC was observed in the children of the first group (G-CSF) compared with those of the second group (GM-CSF), but there was no difference in either the incidence of antibiotic therapy administration between the two groups (26% vs 25%) or the length of hospitalization. Both growth factors were well tolerated by all children studied with minimal side effects observed (including bone pain with G-CSF in 2 of 25 children and pruritus with GM-CSF in 1 of 14). We conclude that G-CSF reduces the duration of neutropenia more than does GM-CSF, but the incidence of severe infection and the duration of hospitalization do not differ between children receiving either G-CSF or GM-CSF.

Endogenous plasma levels of granulocyte colony stimulating factor (G- CSF), granulocyte-macrophage colony-stimulating factor (GM-CSF),IL-6 and IL-10 were measured in a total of 70 patients undergoing cytoreductive chemotherapy for treatment of acute leukaemia or non-Hodgkin's lymphomas. the diagnoses were acute myeloid leukaemia (AML; n = 30), acute lymphoblastic leukaemia (ALL;n=6), non-Hodgkin's lymphomas (NHL; n=11) and other malignant haematological disorders including myelodysplastic syndromes (n=23). After chemotherapy, plasma G-CSF was elevated (mean 5.6 ng/ml; range 1.2-10 ng/ml), and was inversely correlated with white blood cell counts (WBC) (r=-0.7, p<0.001). Occurrence of fever (T>38.0 degrees C) during severe myelosuppression (WBC<1x10(9)/1) was associated with an additional increase of G-CSF levels (P<0. (P<0.001). Plasma IL-6 correlated significantly with fever (range <1 to 1100 pg/ml, mean 130 pg/ml; r=0.5, P<0.001) but revealed only a weak association with WBC or platelet counts. In patients treated with recombinant G-CSF (n = 9), an association between IL-6 and fever was still observed after chemotherapy. During the nonfebrile status (total n = 242; AML n = 124), IL-6 levels remained <9 pg/ml in 90% of cases, whereas G-CSF increased with leucopenia (r = -0.72;P<0.001). In contrast, endogenous GM-CSF remained normal and IL-10 showed only a slight increase (21% of samples; maximum 22 pg/ml) in severe leucopenia. In particular, IL-10 levels did not correlate with G-CSF or IL-6 levels. We conclude that systemic release of G-CSF and IL-6 is obviously nit abrogated by cytoreductive chemotherapy in acute leukaemia and NHL may add to the therapeutic efficacy of recombinant cytokines. Also, plasma levels of G-, GM-CSF or IL-6 appear to be regulated by separate mechanisms.
