RESUMO

OBJECTIVES: To survey practices of iron and recombinant human erythropoietin (rhEpo) administration to infants born preterm across Europe. STUDY DESIGN: Over a 3-month period, we conducted an online survey in 597 neonatal intensive care units (NICUs) of 18 European countries treating infants born with a gestational age of <32 weeks. RESULTS: We included 343 NICUs (response rate 56.3%) in the survey. Almost all NICUs (97.7%) routinely supplement enteral iron, and 74.3% of respondents to all infants born <32 weeks of gestation. We found that 65.3% of NICUs routinely evaluate erythropoiesis and iron parameters beyond day 28 after birth. Most NICUs initiate iron supplementation at postnatal age of 2 weeks and stop after 6 months (34.3%) or 12 months (34.3%). Routine use of rhEpo was reported in 22.2% of NICUs, and in individual cases in 6.9%. RhEpo was mostly administered subcutaneously (70.1%) and most frequently at a dose of 250 U/kg 3 times a week (44.3%), but the dose varied greatly between centers. CONCLUSIONS: This survey highlights wide heterogeneity in evaluating erythropoietic activity and iron deficiency in infants born preterm. Variation in iron supplementation during infancy likely reflects an inadequate evidence base. Current evidence on the efficacy and safety profile of rhEpo is only poorly translated into clinical practice. This survey demonstrates a need for standards to optimize patient blood management in anemia of prematurity.

RESUMO

In this case-control study, the erythropoietin (EPO) promoter variant s1617640, linked to high intravitreal EPO concentrations and increased risk of diabetic retinopathy, was not associated with severe retinopathy of prematurity. This finding was observed both in infants with and without recombinant EPO administration.

RESUMO

OBJECTIVE: To investigate the safety and short term outcome of high dose recombinant human erythropoietin (rhEpo) given shortly after birth and subsequently over the first 2 days for neuroprotection to very preterm infants. STUDY DESIGN: Randomized, double masked phase II trial. Preterm infants (gestational age 26 0/7-31 6/7 weeks) were given rhEpo (nt = 229; 3000 U/kg body weight) or NaCl 0.9% (nc = 214) intravenously at 3, 12-18, and 36-42 hours after birth. RESULTS: There were no relevant differences between the groups for short-term outcomes such as mortality, retinopathy of prematurity, intraventricular hemorrhage, sepsis, necrotizing enterocolitis, and bronchopulmonary dysplasia. At day 7-10, we found significantly higher hematocrit values, reticulocyte, and white blood cell counts, and a lower platelet count in the rhEpo group. CONCLUSIONS: Early high-dose rhEpo administration to very premature infants is safe and causes no excess in mortality or major adverse events. TRIAL REGISTRATION: ClinicalTrials.gov: NCT00413946.

RESUMO

Hematopoietic and non-hematopoietic effects of recombinant erythropoietin (Epo) given to preterm infants are controversially discussed. Because renal loss of Epo was significantly higher after intravenous versus subcutaneous Epoetin-beta administration, we suggest a reconsideration of whether subcutaneous recombinant Epo is more efficient and safer because of lower peaks of circulating Epo.
