NCT ID: NCT00737841 Unknown status - Clinical trials for Irritable Bowel Syndrome

Effect of Bifidobacterium on Irritable Bowel Syndrome

PBIBS
Start date: January 2006
Phase: N/A
Study type: Interventional

There has been no data on effect of Bifidobacterium breve on symptoms of patients with irritable bowel syndrome (IBS). We hypothesized that Bifidobacterium breve is effective on symptoms of IBS patients.

NCT ID: NCT00731679 Completed - Clinical trials for Non-Constipation Irritable Bowel Syndrome

Rifaximin 3 Times/Day (TID) for Non-Constipation Irritable Bowel Syndrome (IBS)

TARGET 1
Start date: July 2008
Phase: Phase 3
Study type: Interventional

To evaluate the efficacy of a 14-day course of rifaximin given 3 times a day vs. placebo in providing adequate relief of IBS symptoms.

NCT ID: NCT00731003 Completed - Clinical trials for Irritable Bowel Syndrome

The Effect of Serotonergic Modulation on Intestinal Permeability and Visceral Hypersensitivity in Healthy Individuals and Irritable Bowel Syndrome (IBS) Patients

Start date: April 2009
Phase: N/A
Study type: Interventional

Serotonin, 5-hydroxytryptamin (5-HT), plays an important role in regulating the gastrointestinal functions. In this study we will modulate the serotonin system with acute tryptophan depletion (ATD) and administration of 5-hydroxytryptophan (5-HTP). ATD is based on ingestion of an amino acid drink devoid of the precursor of serotonin and hence caused a decreased serotonin level. 5-hydroxy-tryptophan is the direct precursor of serotonin and its administration, an increased serotonin level is expected. During these interventions, gut permeability and visceral sensitivity will be measured in healthy individuals and patients with irritable bowel syndrome, which is characterized by altered permeability and visceral hypersensitivity.

NCT ID: NCT00730171 Completed - Clinical trials for Chronic Constipation

An Open-label, Long-term Safety Study of Linaclotide in Patients With Chronic Constipation or Irritable Bowel Syndrome With Constipation

Start date: September 2008
Phase: Phase 3
Study type: Interventional

The objective of this study is to assess the long-term safety of linaclotide administered to patients with chronic constipation (CC) or irritable bowel syndrome with constipation (IBS-C).

NCT ID: NCT00728026 Completed - Clinical trials for Irritable Bowel Syndrome

Autonomic Profiles in Pediatric Patients With Cyclic Vomiting Syndrome (CVS), Irritable Bowel Syndrome (IBS),Postural Orthostatic Tachycardia Syndrome (POTS), Functional Abdominal Pain (FAP) or Chronic Nausea

Start date: June 2008
Phase: N/A
Study type: Observational

Retrospectively review the charts of all children who had heart rate variability, deep breathing test, valsalva maneuver, tilt table test, thermoregulatory sweat testing, quantitative sudomotor axon reflex test (QSART) completed and were cared for at Children's Hospital of Wisconsin.

NCT ID: NCT00724126 Completed - Clinical trials for Non-Constipation Irritable Bowel Syndrome

Rifaximin 3 Times/Day (TID) for Non-Constipation Irritable Bowel Syndrome (IBS)

TARGET 2
Start date: July 2008
Phase: Phase 3
Study type: Interventional

To evaluate the efficacy of a 14-day course of rifaximin given 3 times a day vs. placebo in providing adequate relief of IBS symptoms.

NCT ID: NCT00706758 Completed - Clinical trials for Irritable Bowel Syndrome

Structured Patient Education Versus Written Information for Patients With Irritable Bowel Syndrome

Start date: August 2004
Phase: N/A
Study type: Interventional

In this randomized controlled study in patients with irritable bowel syndrome (IBS) we plan to compare the effects of a structured patient group education (IBS school) with receiving only written information in the form of a IBS-guidebook. The effects of the interventions on GI and psychological symptom severity, knowledge and quality of life will be assessed with validated questionnaires at baseline and 3 and 6 months after the intervention.

NCT ID: NCT00702026 Completed - Clinical trials for Irritable Bowel Syndrome

The Effect of a Multispecies Probiotic on Hypersensitivity in Irritable Bowel Syndrome (IBS) Patients

Start date: August 2008
Phase: N/A
Study type: Interventional

The purpose of this study is to determine whether a specifically designed multispecies probiotic decreases visceral hypersensitivity in IBS-patient (defined by an increased pain tolerance threshold). Moreover, the effect on general symptom scores and inflammatory and microbiological parameters will be studied.

NCT ID: NCT00699166 Completed - Clinical trials for Irritable Bowel Syndrome

Efficacy, Safety and Tolerability of DNK333 (25 and 100 mg Bid) in Women With Diarrhea-Predominant Irritable Bowel Syndrome (IBS-D)

CDNK333B2201
Start date: April 2004
Phase: Phase 2
Study type: Interventional

This study will evaluate the tolerability, safety and efficacy of DNK333 against diarrhea caused by Irritable Bowel Syndrome in women.

NCT ID: NCT00693732 Completed - Clinical trials for Irritable Bowel Syndrome

Validation of Surrogate Measures in Irritable Bowel Syndrome (IBS)

Start date: February 2009
Phase: Phase 4
Study type: Interventional

Visceral and somatic hypersensitivity as evidence of central sensory sensitization occur in the majority of Irritable Bowel Syndrome (IBS) patients. We recently demonstrated abnormal endogenous pain modulation as a cause of the sensitization in IBS and identified the underlying dysfunctional neuromatrix using functional MR-imaging (fMRI). Endogenous pain mechanisms regulate, fine-tune and integrate sensory and homeostatic, including neuroendocrine, immune and autonomic nervous system processes. Specific measures of sensitization and endogenous pain modulation correlate with clinical measures of somatic and neuropathic pain, suggesting usefulness as surrogate markers for clinical pain outcomes. Validation of experimental measures as surrogate markers in IBS would provide a considerable advance in pathophysiological and therapeutic research in this pharmacoeconomically burdensome disease.
