Studies in these patients, along with clinical trials of i.v. iron and recombinant human erythropoietin (rHuEPO) therapy, have furthered our understanding of the relationship between erythropoietin, iron, and erythropoiesis. With supplemental oral iron, the endogenous erythropoietic response to routine autologous blood donation and to the anaemia of chronic illness has been shown to be modest ...
