Clinical Trial Summary

The investigators aim was to assess whether 6 weeks of oral intake of the wheat-derived prebiotic fiber arabinoxylan or oat-derived beta-glucan could improve intestinal barrier function against drug-induced barrier disruption in a general population of elderly people, in a randomized double blinded placebo-controlled clinical trial.


Clinical Trial Description

The study consisted of a 9 week clinical trial to which the study participants orally ingested two different prebiotic compounds/one placebo for a total of 6 weeks.

The primary outcome was intestinal permeability which was measured before/after indomethacin intake before starting with the prebiotic supplementation and repeated 6 weeks afterwards.

Indomethacin is an NSAID known to artificially increase the intestinal permeability. The prebiotic fibers arabinoxylan and oat-derived beta-glucan have not been investigated for their effect on intestinal permeability in older adults.

Intestinal permeability was investigated using the multi-sugar permeability test. Participants ingested a water solution containing 5 sugar probes that are taken up in different parts of the gut. These sugars are later recovered in the urine at two different time points, reflecting gastroduodenal, small intestinal and colonic permeability. ;
