Summary
Early feeding with casein hydrolysate formula (CHF) in infants led to lower immunoglobulin E (IgE) levels and increased macromolecular absorption compared to human milk (HM) or cow-milk formula (CMF). These effects persisted for months, suggesting long-term immune and digestive impacts.
Area of Science:
- Neonatal nutrition
- Immunology
- Gastroenterology
Background:
- Infant feeding practices significantly influence immune system development and gut health.
- Understanding the impact of different early feeding regimens is crucial for infant health outcomes.
Purpose of the Study:
- To investigate the effects of early feeding with human milk (HM), cow-milk formula (CMF), or casein hydrolysate formula (CHF) on infant immune markers and macromolecular absorption.
- To compare the long-term immunological and gastrointestinal responses to different neonatal diets.
Main Methods:
- Randomized controlled trial involving 130 healthy term infants.
- Three feeding groups: HM, CMF, CHF for the first 3 days, followed by exclusive breastfeeding.
- Blood samples analyzed for serum IgE and serum alpha-lactalbumin (S-alpha LA) at specific time points.
- Macromolecular absorption assessed via S-alpha LA concentrations.
Main Results:
- Casein hydrolysate formula (CHF) group showed significantly lower median serum IgE at 2 and 4 months compared to human milk (HM) group.
- CHF group exhibited significantly higher median S-alpha LA concentrations at 2 months versus HM and CMF groups.
- No significant differences observed between cow-milk formula (CMF) and human milk (HM) groups.
Conclusions:
- Early exposure to casein hydrolysate formula may modulate infant immune responses, indicated by reduced IgE levels.
- Casein hydrolysate formula appears to enhance macromolecular absorption in infants.
- Findings suggest distinct immunological and absorptive pathways influenced by neonatal dietary interventions.
