- Excessive-dose erythropoietin didn’t enhance outcomes for infants with hypoxic ischemic encephalopathy.
- Managed cooling inside 6 hours of beginning stays the most effective remedy for beginning asphyxia.
HONOLULU — Erythropoietin didn’t scale back the chance for demise or extreme incapacity amongst infants with hypoxic ischemic encephalopathy already being handled with hypothermia, in keeping with the outcomes of a section 3 randomized managed trial.
“Hypoxic ischemic encephalopathy (HIE) stays a feared complication when issues go improper throughout the beginning of a child, occurring in about one to 3 per 1,000 births in high-income international locations,” Helen G. Liley, MBChB, FRACP, a professor at The College of Queensland in South Brisbane, Australia, instructed Healio.

Liley and colleagues performed a section 3 randomized managed trial of 311 infants with HIE, often known as beginning asphyxia, at 25 amenities in Australia, New Zealand and Singapore between 2016 and 2022. They assigned half of the infants to be handled with hypothermia alone — the usual of take care of neonates with HIE — and the opposite half to be handled with hypothermia and 5 1,000 items/kg doses of erythropoietin each different day for 9 days after beginning. The first end result was demise or extreme incapacity as much as age 2 years.
The researchers didn’t discover a vital distinction within the threat for demise or incapacity between the erythropoietin group and the placebo group (35.3% vs. 29.4%; RR = 1.2; 95% CI, 0.85-1.7).
“Erythropoietin stays secure and extremely beneficial for selling crimson cell manufacturing in sure sorts of anemia, however there is no such thing as a proof to make use of it to assist infants who’re receiving the present customary of remedy for HIE, which is a 3-day course of managed cooling to round 33.5°C, began inside 6 hours of beginning,” stated Liley, who introduced the findings at PAS 2025.
The outcomes supported findings from one other trial printed in The New England Journal of Drugs in 2022 that was performed in the US.
“Collectively, each trials present larger certainty of proof about this lack of profit,” Liley stated.
A number of the outcomes have been encouraging, although. Liley stated the charges of demise and incapacity have been decrease amongst infants on this trial in contrast with cooling trials from 20 years in the past.
“We now have higher info to present mother and father about outcomes, they usually do have some room for hope,” she stated.
Another remedies for HIE are being examined, Liley stated, together with melatonin, neurohormones and stem cells.
She famous that the reason for HIE was identified for about half of the infants within the research, together with occasions like separation of the placenta, uterine rupture or the child getting caught throughout beginning. She stated researchers might want to discover higher methods to anticipate the chance for HIE and forestall it.
