Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

To explore the effects of enteral choline and DHA supplementation on plasma choline and DHA-PC concentrations and metabolism, this randomized controlled study will assign 40 preterm infants to 1 of 4 groups: standard care, choline supplementation, DHA supplementation, and choline and DHA supplementation.

After 7 days of supplementation, a single dose of stable isotope labelled choline will be administered and the kinetics of newly synthesized DHA-PC determined to assess plasma levels, uptake and distribution of choline and DHA.

This study is designed to inform larger studies evaluating this approach of enteral co-application of choline and DHA on clinical important outcomes.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

In utero, there is a constant high supply of choline to the fetus. Preterm delivery disrupts this maternal-fetal choline-transfer. We have shown that choline plasma levels rapidly half after preterm delivery. We also demonstrated that plasma DHA-PC rapidly falls after preterm delivery. DHA supplementation has been evaluated and found safe, however the clinical benefits have been smaller than expected. We speculate that choline deficiency may have contributed to the smaller than expected benefit of DHA supplementation in the past.

This study verifies the hypothesis that concomitant supply of choline and DHA will improve DHA-PC availability and turn-over. This is important because DHA-PC is the transport molecule for the DHA transport to the brain and the retina.

To explore the effects of enteral choline and DHA supplementation on plasma choline and DHA-PC concentrations, this randomized controlled study will assign 40 preterm infants to 1 of 4 groups: standard care, choline supplementation, DHA supplementation, and choline and DHA supplementation.

After 7 days of supplementation, a single dose of stable isotope labelled choline will be administered and the kinetics of newly synthesized DHA-PC determined to assess plasma levels, uptake and distribution of choline and DHA.

This study is designed to inform future larger studies evaluating this approach of enteral co-application of choline and DHA on important clinical outcomes.
