Effect of Erythropoietin on Neurodevelopmental Outcomes in Very Preterm Infants With Intraventricular Hemorrhage
February 25, 2021 updated by: Changlian Zhu, Zhengzhou University
Erythropoietin (EPO) has been shown to be neurotrophic and neuroprotective in several animal models and some clinical studies.
Our hypothesis is that EPO could improve long-term neurological outcomes in very preterm infants with intraventricular hemorrhage (IVH).
The aim of this study is to evaluate the long-term neuroprotective effect of repeated low-dose EPO (500 U/kg) in very preterm infants with IVH.

Detailed Description
IVH is one of the most common complications in preterm infants.
Nearly 60% of preterm infants with grade III-IV IVH develop severe neurodevelopmental outcomes.
There are currently no effective treatments to prevent preterm infants with IVH from developing ventricular dilation or serious neurological disabilities.
Recent studies have shown that EPO could improve neurodevelopmental outcomes in preterm infants with grade III-IV IVH.
However, the dose and course of EPO in preterm infants is still uncertain.
The purpose of the study was whether repeated low-dose EPO (500 U/kg, every other day, for 2 weeks) given to very preterm right after the diagnosis of IVH could improve long-term neurological outcomes.
Very preterm infants with gestational age of ≤ 32 weeks who are diagnosed with IVH within 72 hours after birth in NICU are eligible for enrolment.
After informed consent is obtained, infants will be randomly assigned to EPO group or vehicle group.
The primary outcome is whether EPO improves mortality and neurological disabilities in very preterm infants with IVH at 18 months of corrected age, and the secondary outcome was whether EPO decrease the incidence of cerebral palsy, MDI<70, blindness, and deafness.

Experimental: Erythropoietin
EPO is administered 500IU/kg, intravenously after diagnosis of IVH within 72h after birth, and every other day for 2 weeks.
Recombinant human erythropoietin was configured by the hospital pharmacy intravenous Centre Configuration, melted configured with saline to 1ml/kg solution.
