[Fat absorption in the premature newborn infant]
Summary
Fat malabsorption in preterm infants stems from low pancreatic lipase and bile salt concentrations. Partially using non-heat-treated human milk can significantly improve lipid absorption in these vulnerable infants.
Area of Science:
- Neonatology
- Gastroenterology
- Pediatric Nutrition
Context:
- Preterm infants often experience fat malabsorption, impacting their growth and development.
- Understanding the underlying mechanisms is crucial for effective nutritional support.
- Current management strategies require optimization to address specific infant needs.
Purpose:
- To review the etiopathogenesis and clinical implications of fat malabsorption in preterm infants.
- To identify the primary factors contributing to inadequate lipid absorption.
- To evaluate potential strategies for improving fat absorption.
Summary:
- Inadequate lipid absorption in preterm infants is primarily due to low pancreatic lipase activity and reduced intraluminal bile salt concentrations, impairing lipid solubilization.
- While intragastric lipolysis may offer compensation, and chylomicron formation/transport appear functional, their efficiency in neonates warrants further investigation.
- Non-heat-treated human milk, with its bile-stimulated lipase, is identified as a key intervention to enhance fat absorption.
Impact:
- Provides a comprehensive overview of fat malabsorption in preterm neonates.
- Highlights the critical role of pancreatic lipase and bile salts in neonatal lipid digestion.
- Suggests a practical, evidence-based approach using human milk to improve nutritional outcomes in preterm infants.
