NCT ID: NCT03514784 Recruiting - Clinical trials for Autism Spectrum Disorder

Combination Probiotic: BB-12 With LGG (Different Doses) in Treating Children With Autism Spectrum Disorder

Start date: May 2016
Phase: Phase 1/Phase 2
Study type: Interventional

This protocol is a blinded randomized controlled study of the effects of BB-12 with LGG at different doses in 70 healthy children with autism spectrum disorders at lower and higher doses over an 56-day period and a 28- day observation period. The study is being conducted in order to assess safety and tolerability of the probiotic (BB-12 with LGG) at 2 different doses of BB-12 with LGG. Identifying effects on behaviors in healthy children with ASD using SRS-2 and ABC, GI symptoms using GI symptom severity index, and relevant biomarkers of inflammation, microbiota, and metabolites. Primary testing and procedures will be conducted at the University of Texas Health Science Center at Houston and Memorial Hermann. Biomarker identification includes Integrative analysis of plasma metabolome and stool microbiota will be conducted with the collaboration of Dr. Ruth Ann Luna and Dr. Jim Versalovic at Alkek Center for Metagenomics and Microbiome Research, Department of Molecular Virology & Microbiology of Baylor College of Medicine.

NCT ID: NCT03403387 Recruiting - Clinical trials for Gastrointestinal Symptoms

Effects of GlutenShield, a Prebiotic, Probiotic, and Enzyme Supplement, on the Gut Microbiome of Adults With GI Symptoms

Start date: January 22, 2018
Phase: N/A
Study type: Interventional

This study evaluates the effects of combination probiotic, prebiotic, and enzyme supplementation on the colonic microbiome of individuals with GI symptoms (e.g. diarrhea, constipation, increased gas). Half of the participants will receive the placebo while the other half will receive the supplement for 28 days.

NCT ID: NCT02277431 Completed - Abdominal Pain Clinical Trials

Probiotic Supplementation Among Adults With Recurrent Gastrointestinal Symptoms

Start date: December 2014
Phase: Phase 2/Phase 3
Study type: Interventional

Participants experiencing recurrent gastrointestinal symptoms in this double-blind, randomized, controlled trial will receive either a commercially-available probiotic dietary supplement or placebo. The investigators hypothesize that participants in the probiotic dietary supplement group will experience greater improvement in their gastrointestinal symptoms than participants in the placebo group.

NCT ID: NCT02054455 Completed - Clinical trials for Gastrointestinal Symptoms

Proton Pump Inhibitors and Gastrointestinal Symptoms

Start date: November 2012
Phase: Phase 4
Study type: Interventional

The aim of the study is to evaluate the potential protective effect of Lactobacillus paracasei subspecies paracasei F19 administration on bowel symptom onset in patients with gastro-esophageal reflux disease at long-term PPI treatment.

NCT ID: NCT01964599 Completed - Clinical trials for Gastrointestinal Symptoms

Potato Fiber and Gastrointestinal Function: Phase 3

Start date: January 2014
Phase: N/A
Study type: Interventional

The primary physiological impacts of fiber intake include the gastrointestinal effects of stool bulking, increased stool frequency and decreased gastrointestinal transit time (GTT). Fermentation of resistant starches by microbiota increases bacterial numbers, which increases fecal bulk and may impact frequency and transit time. The purpose of this study is to determine the effects of resistant potato starches (potato fiber) on stool frequency, transit time and microbiota in healthy individuals.

NCT ID: NCT01927900 Completed - Gut Microbiota Clinical Trials

The Effects Of HMO On The Faecal Microbiota And On Gastrointestinal Symptoms In Healthy Volunteers

HMO-VOL
Start date: May 2014
Phase: N/A
Study type: Interventional

The study is a randomised, placebo-controlled, double-blind, parallel, dose-finding study with healthy volunteers. A total of 100 male and female volunteers will be included. The volunteers will be randomized into one of 10 groups, each of 10 participants, consuming either active product in various mixes and doses (9 groups) or placebo product (1 group) for 2 weeks. The 9 groups receiving active product will receive either one of two Human Milk Oligosaccharides (HMOs) alone or in combination at different doses. The primary purpose of the study is establishing the effects of various compositions and doses of HMOs on the faecal flora and on gastrointestinal symptoms in health adults.

NCT ID: NCT01184456 Completed - HIV Infection Clinical Trials

A Controlled Trial to Evaluate the Effects of GanedenBC30 on the Immune System

Start date: August 2010
Phase: Phase 2
Study type: Interventional

Improvement in the rate of bacterial translocation may lead to a decrease in a chronic inflammatory response thereby decreasing CD4 destruction and HIV proliferation. By the addition of probiotics we hope to show a reduction in LPS leading to a decrease in chronic inflammation and therefore an improvement in immune markers.

NCT ID: NCT01171014 Completed - Clinical trials for Gastrointestinal Symptoms

Effect of Bifidobacterium Lactis HN019 on Colonic Transit Time and Digestive Symptoms

Start date: June 2009
Phase: Phase 2/Phase 3
Study type: Interventional

The purpose of this study was to investigate the dose response effect of Bifidobacterium lactis HN019 supplementation on colonic transit time and gastrointestinal symptoms.

NCT ID: NCT01116388 Completed - Autism Clinical Trials

A Study to Assess the Role of a Gluten Free-dairy Free (GFCF) Diet in the Dietary Management of Autism Associated Gastrointestinal Disorders

GFCF
Start date: April 2010
Phase: N/A
Study type: Interventional

Doctors at MassGeneral Hospital for Children (MGHfC) are doing a research study to learn if a gluten free-dairy free (GFCF) diet is helpful in improving gastrointestinal symptoms associated with autism. Hypothesis: The gluten free/casein free diet (GFCF) will result in a higher proportion of subjects having reduction in gastrointestinal (GI) symptoms associated with autism spectrum disorders (ASD). Primary Study Objective: - To assess the effect of a GFCF diet on GI symptoms associated with ASD. Secondary Objectives: - To assess if improvements in GI symptoms result in improvements in autistic behavior when using a GFCF diet in the dietary management of GI symptoms associated with ASD - To determine the nutritional impact of a GFCF restrictive diet - To assess the role of food allergies in the manifestation of GI symptoms This is a 14-week study that requires between 5 & 9 office visits. All study related activities -including physical exams, blood samples and allergy testing - and an amino acid based supplement drink, are at no cost. Research study visits will take place at MGHfC in Boston, or at Newton Wellesley Hospital in Newton, or at Lurie Center/LADDERS in Lexington.
