Preterm infants with intraventricular haemorrhage enrolled in the EpoRepair trial, in 8 Swiss and Austrian tertiary neonatal units (n= 121).
Intravenous high-dose erythropoietin (n= 60).
Placebo (n= 61).
The median birth weight was 832 g (IQR, 687-990 g) in the erythropoietin group and 870 g (IQR, 680-1110 g) in the placebo group. Median gestation was 26.1 weeks (IQR, 24.8-27.3 weeks) in the erythropoietin group and 27.0 weeks (24.9-28.1 weeks) in the placebo group. Both groups had similar baseline characteristics and morbidities. Up to term-equivalent age (TEA), 10 newborns died (16.7%) in the erythropoietin group, and 5 newborns (8.2%) died in the placebo group (adjusted odds ratio, 2.24 (95% CI 0.74 to 7.66)). Infants receiving erythropoietin had higher mean haematocrit levels. Conventional magnetic resonance imaging at TEA for 100 infants showed no significant differences in global or regional brain injury scores.
