摘要: Initial studies have shown that recombinant human interleukin-6 (rhIL- 6) induces anemia. Until now, the pathophysiologic mechanism of this induced anemia has been unknown. To unravel underlying mechanism, we examined 15 cancer patients receiving rhIL-6 as an antitumor immunotherapy in a phase II study. was administered subcutaneously at 150 micrograms once daily for 6 consecutive weeks. Various hematologic and biochemical parameters were measured weekly during treatment 4 weeks after discontinuation. determine plasma volume red blood cell (RBC) volume, radioisotope dilution assays with labeled autologous RBCs serum albumin performed before administration on day 8 therapy. Hemoglobin levels decreased (mean change +/- SE) 7% 1.5% within 3 days start therapy (P
