title: [Influence of iron metabolism on the efficacy of r-HuEPO (recombinant human erythropoietin) treatment of anemia in children on hemodialysis].
abstract: Recombinant Human Erythropoietin (r-HuEPO) is efficient in the treatment of anaemia in terminal renal failure under dialysis. Five pediatric patients, who were under periodic hemodialysis, were treated and the interaction between the metabolism of iron and the response to r-HuEPO was studied in particular. In two patients it was noticed that a significant reduction of hematic ferritin levels occurred, while an efficient erythropoietic activity was maintained. On the contrary, three patients showed iron deficiency characterized by a reduced percentage of total transferrin saturation in the plasma, in the presence of high levels of ferritin in the blood. Also discovered was a missing increase or even a fall of the hemoglobin values that were obtained till now. In these cases, the increase of the hormone dose didn't lead to an improvement, that could only be obtained by the oral or parenteral administration of iron. The Authors in conclusion affirm that iron deficiency is the first cause to be searched for and to be corrected in the presence of missing hemoglobin increase even with adequate doses of r-HuEPO.
