Purpose: We investigated the effects of early postnatal administration of erythropoietin (EPO) on neurodevelopmental outcomes and morbidities in preterm infants with severe grades of intraventricular hemorrhage (IVH).
Methods: We retrospectively reviewed the medical records of preterm infants of gestational age 23+0 weeks to 31+6 weeks, who were diagnosed with severe grades of IVH and received EPO over at least 2 weeks. We compared clinical characteristics, major complications, and neurodevelopmental impairment between the two groups. The primary outcome was severe neurodevelopmental impairment at 18 to 26 months of corrected age. Severe neurodevelopmental impairment was defined as a mental developmental index or psychomotor developmental index of <70 on the Bayley Scales of Infant Development II or diagnosis of cerebral palsy.
Results: The study included 33 preterm infants (mean gestational age 25.2±1.6 weeks and mean birth weight 775.1±224.5 g). EPO was administered at a dose of 400 or 1,000 IU/kg thrice weekly and was maintained over a mean period of 58.6± 25.9 days beginning from 10.7±6.9 days after birth. We observed no difference in perinatal characteristics between the EPO (n=14) and the control group (n=19). Similarly, severe neurodevelopmental impairment rates did not differ between the EPO (85.7%) and control groups (78.9%). The incidence of neonatal morbidities including bronchopulmonary dysplasia, necrotizing enterocolitis, and retinopathy of prematurity was also similar between the EPO and control groups.
Conclusion: Early administration of EPO did not reduce the risk of severe neurodevelopmental impairment in preterm infants with severe IVH.
