A Randomized, Double-Blind, Technology-Enabled Trial to Evaluate the Impact of a Multi-Strain Synbiotic (DS-01) on Metagenomic Stability and Metabolic Output of the Gut Microbiota.
Purpose of Study: This study aims to assess the impact of multi-strain consortia of 24 commensal organisms across 12 species with extensive strain-specific in vivo data, assessing a range of gastrointestinal symptoms without negatively altering the naive gut microbiota. High-throughput shotgun DNA sequencing will provide an opportunity for ‘-omics’-based analyses of the gut microbiota, which can be augmented by the metabolite profiles resulting from total microbial activity in the gut. Since many of these metabolites are bioeffector molecules acting upon the host, such analysis can provide a direct measure of the consequences of microbial activity in the gut and provide a novel integrated data set for patients with IBS. Recruited subjects will also use a smart-phone application to report day to day gastrointestinal symptoms, a patient-centric hallmark of this chronic gut condition.

Irritable Bowel Syndrome and Control Volunteers: Diet Challenge
Purpose of study: The purpose of this study is to study the relationship between the bile acids, short chain fatty acids and bacteria within the intestines. The hypothesis is that changes in the bacterial composition of the stool are associated with the differences in bile acids and short chain fatty acids in patients having irritable bowel syndrome compared to healthy individuals.
Sponsor: Indiana University and NIDDK
Participation: Patients with IBS, ages 18-65 fulfilling Rome IV criteria and asymptomatic controls with no prior history of GI disease or symptoms.
Participants should be on a stable and consistent diet regimen and should not be following an extreme diet intervention such as gluten-free or a low FODMAP diet at the time of study participation.

Lactobacillus LB as Treatment for Irritable Bowel Syndrome With Predominance of Diarrhea (IBS-D)
Purpose of study: The combination of Lactobacillus fermentum and Lactobacillus delbrueckii (Lactobacillus LB) has proven to be effective and safe for treatment of acute diarrhea in children. Also, a clinical trial in adult patients with chronic diarrhea, showed a reduction in the number of daily stools. However, the evidence is not enough regarding the efficacy and safety of Lactobacillus LB for treatment of patients with irritable bowel syndrome with predominance of diarrhea (IBS-D).
Sponsor: Hospital General de Mexico
Participation: Patients meeting Rome IV criteria for IBS-D, without specific medical treatment for the last 4 weeks prior to inclusion in this study.

Purpose of study: To provide treatment to patients with IBS-D.
Sponsor: University of Michigan and Michigan Institute for Clinical and Health Research (MICHR)
Participation: Men and women over the age of 18 diagnosed with IBS-D. Prior colonoscopy or sigmoidoscopy within the past 2 years with random colon biopsies to exclude the presence of microscopic colitis.
About the study: Patients will receive either rifaximin or low FODMAP dietary intervention.

Participants Sought for Study on Complementary Approaches to the Treatment of IBS
Purpose of study: The purpose of this study is to find a complementary treatment to help Irritable Bowel Syndrome (IBS) patients in need of relief.
About The Study: The length of this study will be three weeks long, with a short online intervention everyday to help individuals deal with their body’s reactions to their environments. Participants will have additional surveys to assess their overall state at the beginning of the study, at the end of the three week intervention, and again at six weeks for a follow-up.
Participation: Eligible individuals between the ages of 18 – 65 years of age who are experiencing pain or discomfort associated with their gut. Cannot be smokers or have an inflammatory bowel disease.

Canadian IBS and IBD Patients Needed for IMAGINE (Inflammation, Microbiome, and Alimentation: Gastro-Intestinal and Neuropsychiatric Effects) Study
Purpose of study: The overall aim of IMAGINE Network is to understand the interactions between diet-microbiome-host and find new therapies for the treatment of IBS, IBD and associated psychiatric disorders.
Develop innovative therapies (changes in diet, probiotics, fecal transplants or antibiotics) to improve IBD, IBS and mental health
Improve outcomes of existing therapies through the assessment of diet-microbiome-host interactions
Develop strategies to optimize current therapies to target those who will most benefit from medication as well as identify those in whom medication can be safely discontinued with significant personal benefit and cost savings to the Canadian healthcare system
About The Study: Transform the management of IBD and IBS and associated mental health issues with these disorders.
Sponsor: The IMAGINE (Inflammation, Microbiome, and Alimentation: Gastro-Intestinal and Neuropsychiatric Effects) Chronic Disease Network involves 17 hospitals/universities and 75 researchers across Canada who will study the interactions between the inflammation, microbiome, diet and mental health in patients with inflammatory bowel disease (IBD) and irritable bowel syndrome (IBS). The IMAGINE Network is one of five chronic disease networks in the SPOR (Strategy for Patient Oriented Research) initiative of CIHR (Canadian Institutes of Health Research).
Participation: Persons from across Canada are being invited to participate in the IMAGINE Network. You may be eligible to participate in this study if you have been diagnosed by your physician with Irritable Bowel Syndrome (IBS), Inflammatory Bowel Disease (IBD), including ulcerative colitis or Crohn’s disease or are a healthy individual without gastrointestinal symptoms.
You will not be eligible to participate if you have any of the following criteria:
Age under 4 years.
Past gastrointestinal bypass surgery or major bowel resections unrelated to Crohn’s disease.
Major concurrent illness such as chronic kidney disease, chronic liver disease other than primary sclerosing cholangitis, chronic immune disease unrelated to IBD.
If you have an active eating disorder such anorexia nervosa or bulimia.
If you cannot communicate in either French or English.
Due to the specific nature of this research, we require that participants have not had major gastrointestinal surgery (e.g. Roux en y, bowel resection), do not have additional disease(s) that might affect ability to participate (e.g. decompensated liver disease), prescription or non-prescription drug use that is known to cause gastrointestinal (GI) symptoms (e.g. chronic antibiotic use), fad diets or eating disorders that may cause GI symptoms.
