NCT ID: NCT00607971 Terminated - Clinical trials for Constipation-Predominant Irritable Bowel Syndrome

Long-Term Safety of Renzapride in Women With Constipation-Predominant Irritable Bowel Syndrome (IBS-C)

Start date: April 2006
Phase: Phase 3
Study type: Interventional

The main purpose of this study is to evaluate the long-term safety and tolerability of renzapride at a dose of 4 mg taken once daily for 12 months in women with constipation-predominant irritable bowel syndrome (IBS-C).

NCT ID: NCT00589771 Completed - Clinical trials for Diarrhea Dominant Irritable Bowel Syndrome

Saccharomyces Boulardii in Irritable Bowel Syndrome

SB-IBS
Start date: January 2010
Phase: Phase 3
Study type: Interventional

Various studies have been conducted in past using different strains of probiotics in evaluating IBS symptoms. The results are by no means consistent and the overall impact of probiotics in IBS remains unclear. However, recently O'Mahony L et al have shown that Bifidobacterium infantis 35624 alleviates symptoms in IBS; this symptomatic response was associated with normalization of the ratio of an anti-inflammatory to a proinflammatory cytokine (IL-10/IL-12 ratio), suggesting an immune-modulating role for this organism, in this disorder.Saccharomyces boulardii is a probiotic yeast that has been successfully used for the antibiotic induced diarrhea, prevent relapse of Clostridium difficile and Crohn's disease. It ameliorates intestinal injury and inflammation caused by a wide variety of enteric pathogens.We therefore plan a Double-blind, randomized, placebo-controlled study to assess the effects of Saccharomyces boulardii in improving symptomatology of diarrhea predominant IBS and its effect on quality of life. We also plan to assess the changes in the relative production of anti-inflammatory interleukin (IL)-10 to proinflammatory cytokines (IL-12, IL-8 and TNFα).

NCT ID: NCT00587860 Completed - Clinical trials for Irritable Bowel Syndrome

A Placebo-Controlled Trial of St. John's Wort for Irritable Bowel Syndrome

Start date: February 2006
Phase: Phase 2
Study type: Interventional

This study is being done to see if St. John's wort helps people with irritable bowel syndrome, otherwise known as "IBS". St. John's wort is a herbal supplement derived from the St. John's wort plant. It has been shown to be helpful in several medical conditions such as depression as well as other pain syndromes.

NCT ID: NCT00584571 Completed - Clinical trials for Rectal Hypersensitivity

SAT vs Escitalopram for Rectal Hypersensitivity

Start date: December 2007
Phase: Phase 2
Study type: Interventional

Constipation is a common digestive disorder. After excluding dietary factors, drugs and other secondary causes, at least three broad pathophysiologic subtypes are recognized- dyssynergic defecation, constipation-predominant irritable bowel syndrome (IBS-C) and slow transit constipation (STC), all predominantly affect women and elderly. Many patients also demonstrate abnormal rectal perception with both rectal hyposensitivity and hypersensitivity being common. Recent surveys show that most constipated patients are dissatisfied with current therapy. Also, constipated patients showed significant psychological dysfunction and impaired quality of life. OBJECTIVE: To investigate a novel biofeedback technique of improving rectal hypersensitivity. METHODS: A large compliant balloon attached to a barostat was placed in the rectum in 8 patients with rectal hypersensitivity (urgency/pain threshold <30 mm Hg). Sensory deconditioning was performed by incremental balloon distensions (1-2 mmHg) until normal thresholds were reached.

NCT ID: NCT00584298 Completed - Clinical trials for Irritable Bowel Syndrome (IBS)

Feasibility and Reproducibility of Barostat Assessments of Colorectal Sensation During Colorectal Distention and Its Pharmacological Modulation Using Octreotide

Start date: January 2008
Phase: Phase 1
Study type: Interventional

This study is designed to provide information on feasibility and reproducibility of barostat assessments of colorectal sensory functions and compliance and their pharmacological modulation

NCT ID: NCT00583128 Completed - Clinical trials for Irritable Bowel Syndrome

Safety and Efficacy of AST-120 in Patients With Non-Constipating Irritable Bowel Syndrome

Start date: August 2007
Phase: Phase 2
Study type: Interventional

The objective of this study is to evaluate the safety and effectiveness of the experimental drug AST-120 in treating patients with non-constipating IBS. The study will test whether or not patients receiving AST-120 experience at least a 50% reduction in the number of days with abdominal pain compared to placebo.

NCT ID: NCT00561535 Completed - Clinical trials for Irritable Bowel Syndrome

Effect of a Probiotic, Lactobacillus FARCIMINIS, in Diarrhea Predominant IBS Patients

Start date: October 2007
Phase: Phase 2
Study type: Interventional

Probiotics may improve symptoms in IBS patients. The aim of this study is to test the efficacy of Lactobacillus FARCIMINIS in diarrhea predominant IBS patients according to Rome III criteria.

NCT ID: NCT00555191 Completed - Clinical trials for Irritable Bowel Syndrome

Fructose Malabsorption in Northern Norway

FINN
Start date: September 2007
Phase: Phase 2/Phase 3
Study type: Interventional

Different published studies has shown a possible co-variation between leakage of fructose to the great bowel and exacerbation of irritable bowel syndrome (IBS) symptoms. The aim of the FINN trial is to study the role of fructose malabsorption in patients with IBS in order to evaluate different diagnostic criteria for fructose malabsorption and at the same time study the effect of diet treatment in this cohort of patients and estimate the prevalence of fructose malabsorption.

NCT ID: NCT00554320 Completed - Fibromyalgia Clinical Trials

Effect of Repetitive Transcranial Direct Current Stimulation (tDCS) on Chronic Pelvic Pain

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

We will rigorously test whether modulation of the motor cortex by transcranial direct current stimulation (tDCS) is an effective treatment for patients with chronic pelvic pain through the following specific aims: A) The primary aim of this study is to determine whether transcranial direct current stimulation applied to the motor cortex in patients with chronic pelvic pain induces a significant decrease in the pain or symptoms as compared with sham tDCS. We will also measure changes in the clinical symptom scores of multiple pelvic organs, drug intake (narcotic), anxiety, depression, traumatic stress, as well as overall improvement in the quality of life to assess the effects of this treatment. B) Determine the duration of the clinical effects of tDCS. We will therefore compare the amelioration of pain and related symptoms between active and sham tDCS for one year following treatment. C) Determine whether tDCS changes the threshold for pain detection as compared with sham tDCS. Patients with chronic pelvic pain have a lower threshold for pain as compared to healthy subjects and we hypothesized that this threshold will increase after stimulation with tDCS. D) Finally, we will examine whether 5 days of tDCS treatment is safe for use in chronic pelvic pain patients. Safety will be assessed through neuropsychological tests and adverse event reporting.

ARDIS-1
Start date: September 2007
Phase: Phase 3
Study type: Interventional

The purpose of the study is to determine the efficacy and safety of Rezular (arverapamil) in the treatment of IBS-D.
