BACKGROUND: It is not known whether a moderate dose of oral iron supplementation would further enhance erythropoiesis in recombinant human erythropoietin (EPO)-treated very low-birthweight (VLBW) infants. METHODS: In total, 24 preterm infants with birthweights750-1499 g were enrolled at the age of 14-28 days toreceive 400 IU/kg per week EPO subcutaneously for 8 weeks. The infants were randomly allocated either to receive oral iron supplementation 4 mg/kg per day or to serve as controls. RESULTS:Hemoglobin and the absolute reticulocyte count in the iron supplementation and the control groups remained identical throughout the study period, whereas serum ferritin was significantly lower in the control group at study exit and follow up. Rates of treatment success (no need for transfusion and hemoglobin never below 8 g/dL) also did not differ between the groups. CONCLUSIONS: In this study we did not find a clear advantage in a moderate dose of oral iron supplementation on erythropoiesis in EPO-treated VLBW infants. Whether a higher dose would lead to enhanced erythropoiesis remains to be answered.
