Using the steatocrit to determine optimal fat content in modular feeds

Area of Science:

• Pediatrics
• Gastroenterology
• Nutrition

Background:

• Infants with protracted diarrhea often receive intragastric modular feeds.
• Assessing fat absorption and tolerance is crucial for managing these infants.

Purpose of the Study:

• To measure steatocrit variability in infants with protracted diarrhea on modular feeds.
• To determine fat tolerance limits by observing steatocrit changes during increased fat intake.
• To explore the relationship between steatocrit, fat intake, and weight gain.

Main Methods:

• Steatocrit was measured in infants with protracted diarrhea receiving intragastric modular feeds.
• Measurements were taken during constant fat intake to assess variability.
• Steatocrit was monitored during increased fat intake to evaluate fat tolerance.
• Variability was compared between infants with protracted diarrhea and healthy breastfed infants.

Main Results:

• Median between-stool and between-day steatocrit variabilities were 2% and 11% in infants with protracted diarrhea.
• Steatocrit variability in healthy infants with steatorrhea was not significantly different.
• Steatocrit increased significantly with increased fat intake, showing a positive correlation.
• A significant negative correlation was observed between steatocrit and weight gain, with negligible gain around 30% steatocrit.

Conclusions:

• Steatocrit is a variable measure in infants with protracted diarrhea.
• High steatocrit levels (around 30%) are associated with poor weight gain, suggesting impaired fat absorption or tolerance.
• These findings have implications for optimizing nutritional management in infants with chronic diarrhea.
