Abstract
Eleven anemic children and adolescents with a median age of 14 years (range six months-20 years) on chronic hemodialysis were treated with recombinant human erythropoietin (rHuEPO) intravenously three times a week for an average of 9.2 months. After eight weeks of therapy, hematocrit rose from 20.3 ± 1.4% to 31.7 ± 0.7% (0.20 ± 0.01 to 0.31 ± 0.007, p <0.001, mean ± SEM). After reaching the target hematocrit of 30% to 33% (0.30 to 0.33), doses were adjusted individually. Blood transfusions were eliminated in all but one patient. All patients experienced an increase in appetite and energy level. Serum ferritin concentrations decreased in all patients who reached target hematocrit and seven required iron supplementation. Hypertension worsened in two patients and developed in two others. One patient's vascular access clotted. Dialysis efficiency and heparin requirements during dialysis did not change significantly. We conclude that rHuEPO is safe, effective, and should be recommended as treatment for anemia in children and adolescents on hemodialysis, but close monitoring for the development of hypertension and/or iron deficiency is necessary
