Objective: We previously reported improved neurodevelopment at 2 and 4 years among preterm infants treated with erythropoietin or darbepoetin, known as erythropoiesis-stimulating agents (ESAs). We now characterize longitudinal outcomes through 6 years.

Methods: Children randomized to ESAs or placebo were evaluated at 6 years. Healthy-term children served as controls. Tests of cognition and executive function (EF) were performed.

Results: Cognitive/EF scores remained similar between 4 and 6 years within each group (ESA: 43 children; placebo: 17 children; term: 21 children). ESA recipients scored higher than placebo on Full-Scale IQ (94.2 ± 18.6 vs. 81.6 ± 16.7, p = 0.022), and Performance IQ (97.3 ± 16.2 vs. 81.7 ± 15.2, = 0.005). Aggregate EF trended better for the ESA group. Term controls scored better than placebo on all measures. ESA and term controls scored similarly on cognitive and EF tests.

Conclusion: ESA recipients had better outcomes than placebo recipients, and were similar to term children. ESAs may improve long-term cognition and executive function in preterm infants.

Keywords: Neurodevelopmental impairments, neuroprotective interventions, darbepoetin, erythropoietin, apoptosis, BRITE.
