Popis
EPO has been safely used for prevent preterm anemia and recent studies have shown the neuro-protective effect. Our hypothesis is that EPO could prevent preterm brain injury and reduce the rate of premature death and disability from encephalopathy. The aims of this study include: to investigate the safety and efficacy of EPO by using 1000u/kg higher than the dose of anemia treatment (250u/kg); to evaluate the effect of EPO on neurodevelopment in preterm infants; to detect biological and imaging indicators of EPO. Eligible premature infants will be enrolled in this double-blind, placebo-controlled randomized trial from the neonatal neurological intensive care unit (NNICU) at 7 Children's Hospital in 6 provinces of China. Subjects will be enrolled within the first 24 hours of life and randomly assigned to receive Epo or saline vehicle placebo. Standard NICU care will be provided to all subjects. Pharmacokinetic data, serial brain electrophysiologic and imaging exams, circulating inflammatory mediators, biomarkers and complications like polycythemia, neutropenia, thrombocytopenia, hypertension, sepsis, hemorrhage, seizure, necrotizing enterocolitis (NEC), persistent ductus arterious (PDA), apnea of prematurity, pulmonary haemorrhage, pulmonary hypertension, Prolonged blood coagulation time, retinopathy of prematurity (ROP), cardiac arrhythmia, major venous thrombosis, Renal failure treated with dialysis, pneumonia, pulmonary airleak and chronic lung disease will be collected at established time points during the study period. At 18 months corrected age, subjects will undergo a neurodevelopmental evaluation assessing for cerebral palsy, Bayley Scores of Mental Development Index (MDI) use.
