Elderly Clinical Trial
Official title:
Effects of β-glucan Based Dietary Fibres on Indomethacin-induced Hyperpermeability and Gut Microbiota Composition in Elderly: A Randomized Placebo-controlled Crossover Clinical Trial
The investigators aim was to compare healthy young adults, senior orienteers (model of healthy ageing) and elderly with gastrointestinal symptoms on intestinal permeability, microbiota compositions and well-being. In addition, assess whether 3 weeks of oral intake of soluble or dispersible forms yeast-dervied beta-glucan could improve intestinal barrier function against drug-induced barrier disruption vs placebo for a cohort of elderly people with gastrointestinal symptoms, in a randomized double blinded placebo-controlled cross-over clinical trial.
Baseline samples for measurements of intestinal permeability (multisugar test), microbiota composition (faecal samples) and well-being (questionnaires) were collected during the first week for: Young healthy adults (healthy young controls) Senior orienteers (healthy elderly controls) Elderly with gastrointestinal (GI) symptoms Thereafter only the elderly with GI symptoms continued into the randomized cross-over trial where they were blindly and randomly distributed one of the following: Soluble yeast-derived beta-glucan, dispersible (whole) yeast-derived beta-glucan and placebo. Each supplement was taken for 3 weeks with a 1 week washout until all participants had taken all supplements. Towards the end of each supplement period, samples for measurement of intestinal permeability and microbiota were collected, in addition to questionnaires being filled out. ;
