Xylose absorption in infants with severe prolonged diarrhoea
Summary
Oral feeding may limit energy for infant tissue repair after severe diarrhea. Xylose tests showed impaired absorption in most infants, suggesting early nutritional intervention is crucial for recovery.
Area of Science:
- Pediatric Gastroenterology
- Nutritional Science
- Infant Health
Background:
- Severe prolonged diarrhea in infants can compromise energy supply for tissue repair.
- Oral feeding may be insufficient to meet the increased metabolic demands during recovery.
Purpose of the Study:
- To assess carbohydrate absorption in infants recovering from severe dehydrating diarrhea.
- To evaluate the impact of prolonged diarrhea on energy metabolism and nutrient absorption.
Main Methods:
- Xylose tolerance tests were performed on 8 female infants hospitalized for severe dehydrating diarrhea.
- Infants had received hospital treatment for 7 days prior to testing.
Main Results:
- Seven out of 8 infants exhibited flat xylose tolerance curves.
- Five of these infants showed very low xylose absorption levels, indicating malabsorption.
- This suggests impaired energy supply due to compromised nutrient absorption.
Conclusions:
- Severe prolonged diarrhea significantly impacts carbohydrate absorption in infants.
- Early nutritional interventions, including hyperalimentation or elemental diets, may be necessary to support tissue repair.
- Prompt treatment with antibacterial agents and anion exchange resins could potentially reduce morbidity.
