Supplementing preterm infant nutrition with bioactive factors shows promise for reducing complications. However, more high-quality research is needed before widespread clinical use, with ongoing trials on insulin and vitamin A potentially offering clearer answers.
Area of Science:
- Neonatal nutrition
- Human milk bioactive factors
- Clinical trial research
Background:
- Mother's own milk improves outcomes for preterm infants.
- Human milk bioactive factors are explored for nutritional supplements.
- Previous reviews excluded lactoferrin, vitamin D, K, and iron.
Purpose of the Study:
- To review bioactive factors used as supplements in preterm infant enteral nutrition.
- To overview ongoing clinical trials on these supplements.
Main Methods:
- Systematic review of randomized controlled trials.
- Searches conducted in MEDLINE, EMBASE, CENTRAL, and clinical trial registers.
- Exclusion of studies on lactoferrin, vitamins D, K, and iron.
Main Results:
- 17 different bioactive factors were identified across 26 studies.
- Several factors showed encouraging potential effects.
- Three large ongoing trials (n > 500) are investigating enteral insulin and vitamin A.
Conclusions:
- More high-quality studies are necessary before implementing specific bioactive factors into clinical practice.
- Ongoing trials on enteral insulin and vitamin A may provide definitive answers.
