Prebiotic ingestion does not improve gastrointestinal barrier function in burn patients

Area of Science:

• Gastroenterology
• Nutritional Science
• Clinical Research

Background:

• Burn injury significantly alters gastrointestinal (GI) barrier functions.
• Prebiotics are known to support gut health by promoting beneficial bacteria.
• Oligofructose (OF) was investigated for its potential to improve GI permeability in burn patients.

Purpose of the Study:

• To evaluate the efficacy of oligofructose (OF) supplementation in improving gastrointestinal permeability in burn patients.
• To assess the impact of OF on gut barrier function markers during recovery from burns.

Main Methods:

• A randomized, double-blind, placebo-controlled trial involving 41 burn patients.
• Daily ingestion of 6g oligofructose (OF) or sucrose (placebo) for 15 days.
• Gastrointestinal permeability assessed using sucrose and lactulose/mannitol (L/M) excretion tests on multiple days.

Main Results:

• Burn patients exhibited significantly increased GI permeability (sucrose excretion and L/M ratio) at baseline compared to healthy controls.
• GI permeability markers showed significant normalization over the 21-day study period in burn patients.
• No significant differences in the rate of GI permeability normalization were observed between the OF and placebo groups.

Conclusions:

• Regular intake of oligofructose (OF) did not accelerate the normalization of gastrointestinal permeability in burn patients.
• The study suggests that prebiotic supplementation may not be an effective strategy for improving gut barrier function post-burn.
• Further research may be needed to explore other interventions for managing GI dysfunction in burn recovery.
