Respiratory hydrogen secretion: a simple test of bowel adaptation in infants with short gut syndrome
Insights
This study shows that daily breath hydrogen (H2) testing helps infants with short gut syndrome transition to oral feeding. This method monitors carbohydrate tolerance, preventing severe diarrhea and aiding intestinal adaptation.
Area of Science:
- Pediatric Gastroenterology
- Neonatology
- Surgical Gastroenterology
Background:
- Short gut syndrome (SGS) management focuses on transitioning infants from parenteral to enteral nutrition.
- Early feeding is crucial for intestinal mucosal hyperplasia, essential for eventual oral alimentation.
- Previous studies indicated a modular hyposmolar formula aids intestinal adaptation in SGS infants.
Purpose of the Study:
- To evaluate the utility of daily breath hydrogen (H2) testing in managing infants with short gut syndrome.
- To assess the role of breath H2 monitoring in facilitating the transition to total gastrointestinal alimentation.
- To determine if breath H2 testing can prevent complications like severe diarrhea during dietary advancement.
Main Methods:
- Monitoring daily breath H2 levels in infants with SGS receiving a modular hyposmolar formula.
- Using breath H2 results as an early warning for carbohydrate overload and potential malabsorption.
- Adjusting diet volume and composition based on clinical response and breath H2 test outcomes.
Main Results:
- Daily breath H2 testing provided an early warning of carbohydrate overload before clinical signs of malabsorption appeared.
- The test accurately measured the bowel's capacity to utilize specific dietary volumes and caloric densities.
- In three SGS infants, breath H2 testing facilitated the transition to oral alimentation within 3 to 20 weeks, avoiding severe diarrhea.
Conclusions:
- Daily breath H2 testing is a valuable tool for monitoring intestinal adaptation in infants with short gut syndrome.
- This method allows for controlled diet advancement, minimizing the risk of severe diarrhea and enabling a smoother transition to enteral feeding.
- Breath H2 monitoring supports successful oral alimentation, improving outcomes for infants with short gut syndrome.
Abstract:
The prime goal in the management of infants with short gut syndrome is the smooth transition from total parenteral alimentation to total gastrointestinal alimentation. Such transition is dependent upon early feeding to actively promote the intestinal mucosal hyperplasia that is the key to eventual oral alimentation. A modular hyposmolar formula was previously reported to be successful in promoting the intestinal adaptation in several infants with short gut syndrome. Progression of the daily diet was dependent upon the day's clinical response, i.e., whether a change in volume or substrate composition resulted in increased stooling or diarrhea. Diarrhea occurs when the substrate load exceeds the absorptive capacity of the intestine and may be severe enough to require a return to parenteral alimentation until intestinal recovery is complete. Monitoring of daily breath H2 has provided an early warning mechanism to indicate carbohydrate overload in the adapting bowel before clinical signs of malabsorption occur. It provides an accurate daily measure of the bowel's ability to utilize the specific volume and caloric density it is being presented, thereby allowing diet advancement in a controlled fashion. The use of the breath H2 test in three infants with short gut syndrome has assisted in the transition to oral alimentation in 3 to 20 wk without the complications of severe diarrhea.
