Vitamin D for very preterm infants-determining the how, when, and why

Area of Science:

• Neonatology
• Nutritional Science
• Pediatric Research

Background:

• Vitamin D supplementation is common in neonatal intensive care units (NICUs).
• Current clinical trial data on optimal vitamin D dosage for neonates is inconsistent.
• Understanding vitamin D's role in perinatal metabolism is crucial.

Purpose of the Study:

• To review current practices in vitamin D supplementation in US NICUs.
• To highlight the need for further research into optimal vitamin D dosing for preterm infants.
• To emphasize the importance of considering perinatal vitamin D metabolism.

Main Methods:

• Survey of vitamin D dosage practices in United States neonatal intensive care units.
• Review of existing clinical trial results on vitamin D efficacy and safety in neonates.

Main Results:

• The most frequently used vitamin D dose in US NICUs is 400 IU/day.
• Clinical trial results regarding vitamin D's efficacy and safety in NICU settings are inconsistent.

Conclusions:

• The optimal vitamin D dose for preterm infants in the NICU remains undetermined.
• Future research should investigate perinatal vitamin D metabolism, immune function, and organ development.
• Preterm infant vitamin D metabolism is a critical area for ongoing scientific investigation.
