Platelet numbers and circulating haemopoietic progenitor cells were examined in 12 patients with advanced malignancies who were receiving recombinant human interleukin-6 (rhIL-6) as part of an investigation of its thrombopoietic effects. Patients received recombinant glycosylated IL-6 by daily subcutaneous injection for 7 consecutive days in doses of 1, 3 or 10 micrograms/kg/day. Platelet numbers increased reaching a peak on days 12-15 with a mean on day 15 of 198.1% of pre-treatment values. This was accompanied by a significant fall in the mean platelet volume (mean decrease of 10.6%, P = 0.0044). No significant correlation was seen between the IL-6 dose and the change in platelet number. No significant differences were observed between pre- and post-treatment levels of circulating erythroid burst-forming units (E-BFU) and granulocyte macrophage colony-forming units (GM-CFU) but a small significant increase was seen in circulating primitive progenitor cells measured in a plastic-adherent (P delta) assay (P = 0.025). As positive controls, a group of patients treated with cyclophosphamide/G-CSF showed significant increases in GM-CFU (P = 0.018), E-BFU (P = 0.018) and P delta progenitors (P = 0.028). These data suggest that the thrombopoietic effects of IL-6 are mediated at a relatively late stage via effects on megakaryocyte differentiation, with a relatively small effect on circulating haemopoietic progenitors.
