  Purpose

Preterm infants are a risk for multiple transfusions, and the administration of human recombinant erythropoietin (Epo) has been shown to decrease transfusion requirements. Dosing usually occurs three times a week, but extended dosing schedules have been successful in adults. The investigators assessed weekly Epo dosing in preterm infants compared to standard three times weekly dosing.

Detailed Description:

Erythropoietin (Epo) increases and maintains hematocrit using once weekly dosing in adults with anemia due to end stage renal disease. Epo is used in preterm infants to treat the anemia of prematurity, but has not been studied using once weekly dosing. We compared reticulocyte responses of once weekly Epo dosing with thrice weekly dosing in preterm infants.

Infants ≤1,500 grams and ≥7 days of age were randomized to once weekly Epo, 1,200 units/kg/dose, or thrice weekly Epo, 400 units/kg/dose, subcutaneously for 4 weeks, along with iron and vitamin supplementation. Complete blood counts, absolute reticulocyte counts (ARC), transfusions, phlebotomy losses, and adverse events were recorded.
