NCT ID: NCT05821010 Recruiting - Clinical trials for Non-Alcoholic Fatty Liver Disease

Synbiotics and Fecal Microbiota Transplantation to Treat Non-Alcoholic Steatohepatitis

SYNCH
Start date: March 17, 2023
Phase: Phase 2
Study type: Interventional

The goal of this clinical trial is to investigate the therapeutic potential of A. soehngenii and pasteurized A. muciniphila combined with B. animalis subsp. lactis and fructo-oligosaccharides with and without conditioned vegan lyophilized fecal microbiota transplantation capsules to reduce NASH in patients with fibrotic NASH. The main questions to answer are: 1. Can NASH be treated by altering the gut microbiota using LFMT capsules? 2. Can NASH be treated using a syntrophic cocktail of synbiotics and will these strains strengthen the effect of FMT? 3. What are the underlying mechanism by which the aforementioned treatments attenuate NASH? Participants will be treated with FMT-capsules or placebo, and all participants will receive a cocktail of 3 strains of probiotics and one type of prebiotic.

NCT ID: NCT05584254 Completed - Elderly Clinical Trials

Effects of β-glucans on Gut Permeability and Microbiota in Elderly

Start date: April 1, 2015
Phase: N/A
Study type: Interventional

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.

NCT ID: NCT04706858 Completed - Prebiotics Clinical Trials

Integrative Personal Omics Profiling for Dynamic Molecular Phenotypes Monitoring During Fiber Supplementation

Start date: October 15, 2014
Phase: N/A
Study type: Interventional

The investigators propose a comprehensive, multiomic study that will integrate longitudinal data associating changes in specific gut bacteria and host in response to prebiotic fiber supplementation. These data will guide the development of an integrative biological signature relating bacterial-derived metabolites with biological outcome in the host.

NCT ID: NCT04043000 Completed - Probiotics Clinical Trials

Super 13 Pro & Prebiotics on the Human Intestinal Microflora

Start date: October 21, 2019
Phase: N/A
Study type: Interventional

This study aim to investigate the roles of the test article in improving gastrointestinal functions and gut microbiota of humans. A total 40 healthy adults were recruited and randomly divided into experimental and control groups, with 20 subjects each, for a 4-week trial. The subjects took the test article, "Super 13 Pro & Prebiotics" or the control article, "The placebo without Super 13 Pro & Prebiotics" during the 4-week drug-intake period. Fecal specimens were collected at the 0th, 2nd, and 4th weeks of the trial for analyzing the bacterial counts of Bifidobacterium spp., Clostridium perfringens, Lactobacillus spp., and Coliform.

NCT ID: NCT03925597 Recruiting - Prebiotics Clinical Trials

Multiomic Signatures of Microbial Metabolites Following Prebiotic Fiber Supplementation

Start date: January 21, 2020
Phase: N/A
Study type: Interventional

The investigators propose a comprehensive, multiomic study that will integrate longitudinal data associating changes in specific gut bacteria and host in response to prebiotic fiber supplementation. These data will guide the development of an integrative biological signature relating bacterial-derived metabolites with biological outcome in the host. The open sharing of data generated by the proposed research represents a significant public resource that will support and accelerate future novel studies.

NCT ID: NCT03554694 Recruiting - Anxiety Clinical Trials

Gut-brain Axis, Brain Function, and Behaviour.

Start date: May 6, 2018
Phase: N/A
Study type: Interventional

The aim is to test if dietary supplementation with prebiotics reduces measures of anxiety in healthy human participants with high self-reported levels of anxiety. Study will test for an effect on behavioural, neuroendocrine and brain imaging markers of anxiety.

NCT ID: NCT03336385 Completed - Aged Clinical Trials

Prebiotic Supplementation and Intestinal Barrier Function in Elderly: a RCT

Start date: October 12, 2015
Phase: N/A
Study type: Interventional

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.

NCT ID: NCT03312660 Completed - Prebiotics Clinical Trials

Effect of a Kefir Beverage on Immunity and Lipid Profile

Start date: April 10, 2017
Phase: N/A
Study type: Interventional

This is an exploratory cluster randomized controlled trial to evaluate the effect of a kefir beverage, enriched with prebiotics components, on immunity, lipid profile and adiposity in a population-based study, using the family as the intervention unit.

NCT ID: NCT02679183 Completed - Premature Infants Clinical Trials

Medically-Graded Honey Supplementation Formula To Preterm Infants

Honey
Start date: January 2011
Phase: Phase 0
Study type: Interventional

Honey is a natural product that contains multiple nutrients; it is composed of fructose, glucose and fructooligosaccharides that can potentially serve prebiotic functions. It also contains more than 180 substances including amino acids, vitamins, minerals and enzymes. Investigators hypothesized that supplementation of enteral feeds with honey would produce a bifidogenic effect and stimulate the immune response in preterm infants. Investigators randomly assigned subjects to 4 groups receiving 0, 5, 10 and 15 grams of honey daily for 2 weeks and measured their effect on stool colonization, systemic immune parameters and anthropometric measurements.

NCT ID: NCT02118402 Completed - Anemia Clinical Trials

Iron and Prebiotics Fortification in Kenyan Infants

Iro'n'Pre
Start date: July 2014
Phase: N/A
Study type: Interventional

Iron deficiency and anemia are health issues affecting mainly infants and women in developing countries. Iron deficiency in infancy can have long-lasting impact on cognitive and motor development of the child. Iron fortification has shown to be effective against anemia. However, in areas with a high burden of infectious diseases iron may increase the risk of unfavorable gut microbiota composition possibly influencing diarrhea prevalence. Therefore we want to assess the effects of home fortification of complementary food with two iron-containing micronutrient powders (MNPs) with and without the addition of a prebiotic (7.5 g of galactooligosaccharides as GOS-75) compared to a control on the composition of the gut microbiota of Kenyan infants. In addition, iron deficiency may iimpair adaptive immunity. Following Kenyan Minstry of Health guidelines, infants receive their first measles vaccine at 9 months. In this study we will use an MNP with a moderate iron dose of 5 mg, with 2.5 mg of Fe as NaFeEDTA and 2.5 mg of Fe as ferrous fumarate (+Fe). There will be 3 study groups MNP, MNP+Fe and MNP+Fe+GOS. The infants will be enrolled in the study at the age of 6-10 months and will consume a home-fortified maize porridge for four months. At baseline and endpoint (after 4 months of intervention), we will collect blood samples of the infants in order to assess anemia, iron status, and inflammation. In addition, we will assess the effect of iron supplementation on measles vaccine response. Fecal samples (from child and mother) will be collected at baseline, 3 weeks and at endpoint in order to evaluate the changes in gut microbiota and gut inflammation. During the intervention, in a sub-group of children who receive broad-spectrum antibiotics, we will compare how the three different interventions modify the effect of antibiotics on the infant gut microbiota. We will opportunistically select children that are enrolled in the study and who become ill, and who are prescribed antibiotics by the local health care team, according to the local standard of care in the study area. Five additional stool samples from these children will be collected (day 0 (before the first antibiotic dose), 5, 10, 20 and 40) to evaluate the changes in the gut microbiota and gut inflammation. Three years after the study end, we would like to collect a blood and stool sample from the children and examine the iron status and gut microbiome respectively.
