Abstract
Background Erythropoietin (EPO) appears to confer neuroprotection to the injured brain. Randomized clinical trials (RCTs) have demonstrated its safety in neonates with hypoxic-ischemic encephalopathy (HIE); however, the evidence is unclear. The objective of this study was to examine the role of EPO in perinatal HIE by a systematic review and meta-analysis. Methods Database search included Embase, MEDLINE, Cumulative Index to Nursing and Allied Health Literature (CINAHL) and Cochrane Central Register of Controlled Trials (CENTRAL). RCTs reporting a death, neurodevelopmental outcomes or brain injury were included. Two authors extracted the data independently from included studies and assessed the level of evidence (LOE). Results Six RCTs (EPO=5 and darbepoetin α=1) involving 454 neonates were included. A trend toward a lower risk of death was identified in infants treated with EPO [EPO with or without hypothermia: five RCTs, 368 participants, relative risk (RR) 0.74, 95% confidence interval (CI) 0.47-1.19, LOE-low; EPO without hypothermia: four RCTs, 318 participants, RR 0.89, 95% CI 0.49-1.32, LOE-low]. EPO treatment without hypothermia compared to placebo resulted in a reduced risk of cerebral palsy (two RCTs, 230 participants,...Continue Reading
