A Longitudinal Study to Identify IBS Phenotypes Using Fecal Microbiota and Hydrogen Breath Testing

Diarrhea-predominant irritable bowel syndrome (IBS-D) is a highly prevalent but poorly understood condition with limited treatment options. Recent evidence has established small intestinal bacterial overgrowth (SIBO) and alterations in fecal microbiota as potential etiologies in the pathogenesis of IBS-D. Current therapies, including a nonabsorbable antibiotic rifaximin or diet low in ...

Phase

Rifamycin SV-MMX 600 mg Tablets Administered Three or Two Times Daily to Patients With IBS-D

The objective of this study is to evaluate the safety and efficacy Rifamycin SV-MMX 600 mg tablets for patients with diarrhoea-predominant irritable bowel syndrome when administered two to three times daily.

Phase

Diet Reintroduction Study in Irritable Bowel Syndrome

Research Plan Design: Blinded FODMAP reintroduction study Duration of study: 1 year Patient population: Eligible IBS patients Visit 1 (-2 weeks): After providing written informed consent, baseline and descriptive data will be obtained including age, sex, race, pertinent medical history, prior IBS treatments, vital signs, weight, use of concurrent medications ...

Phase N/A

Study to Explore the Therapeutic Effect of Eluxadoline in Treating Irritable Bowel Syndrome With Diarrhea in Children.

The primary objectives of this study are to explore the therapeutic effect of eluxadoline in treating IBS-D in pediatric patients 12-17 years of age, to evaluate the pharmacokinetics of eluxadoline in pediatric patients with IBS-D, and to evaluate the safety and tolerability of eluxadoline in pediatric patients with IBS-D.

Association Between High Faecal Calprotectin Increased Intestinal Permeability and Visceral Hypersensitivity in IBS-D Patients

Irritable bowel syndrome (IBS) is a common functional disorder which affect around 10% of the general population. Abdominal pain and discomfort are associated with transit disorders (diarrhea, constipation, alternating). IBS is defined by Rome III criteria. For clinicians, IBS remains difficult to treat while its pathophysiology remains not completely understood. ...

Phase N/A

fMRI and Visceral Perception Upon Capsaicin Infusion

Brain imaging has shown abnormal brain activations in response to visceral stimulation in patients with the Irritable Bowel Syndrome (IBS) and Functional Dyspepsia (FD). To investigate the possible role of the Nucleus of the Solitary Tract (NTS), the primary relay station in the brainstem for vagal afferents, its activation in ...

Phase N/A

Transplantation of Anaerobic Cultured Human Intestinal Microbiota in Irritable Bowel Syndrome

Diarrhea-dominated irritable bowel syndrome (IBS-D) is studied in subjects by treatment with an anaerobic human intestinal microbiota cultured for 15 years and quality controlled with a specified content of bacterial species regularly over the years. Inclusion criteria is: Diarrheal disease since at least 4 weeks, 18-80 years of age, previously ...

Phase

Efficacy of Open Label Placebo in Children With FGIDs

The purpose of this research study is to see if prescribing an open label placebo to children with functional gastrointestinal disorders will help improve symptoms and their overall quality of life. Open label means you/your child are aware you are taking liquid placebo drops and not an active medication. Symptoms ...

Phase N/A

Study of Performance of Confocal Endomicroscope With Fluorescein Imaging Agent in the Colon

The overall aim of this research project is to evaluate the imaging performance of a confocal endomicroscope. Fluorescein, an FDA-approved topical fluorescent dye, will be used to provide topical mucosal contrast. The purpose of this instrument is to provide real-time endoscopic "histology" to guide endoscopic biopsy or endoscopic mucosal resection ...

Vitamin D Supplementation in IBS

Irritable bowel syndrome (IBS) is a very common functional gastrointestinal disorder affecting nearly 20% of the North American population. IBS is characterized by chronic abdominal, associated with a change in bowel frequency and or consistency that lack a known structural or anatomic explanation. Current treatment for IBS is primarily symptom-based. ...
