Filter by:This randomised, double blind, cross-over study compares the effect (symptoms, fecal bacterial growth, gas production) of three weeks' treatment with lactobacillus plantarum MF 1298 with placebo in patients with irritable bowel syndrome. The results are related to dietary habits, food intolerance and food allergy.
Primary objective: to assess the efficacy of Bacillus clausii versus metronidazole in the eradication of the small intestinal bacterial overgrowth, 30 days after the end of treatment. Secondary objective: to assess the efficacy of Bacillus clausii versus metronidazole in avoiding recurrence of the small intestinal bacterial overgrowth, 90 days after the end of the treatment; to assess the efficacy of Bacillus clausiiversus metronidazole in improving irritable bowel syndrome -related symptoms; to assess the efficacy of Bacillus clausii versus metronidazole in the satisfactory relief of overall irritable bowel syndrome symptoms and of abdominal discomfort or pain; to assess the efficacy of Bacillus clausii versus metronidazole in improving irritable bowel syndrome quality of life.
The purpose of this study is to assess the effects of AV608, a neurokinin 1 (NK-1) antagonist, in subjects with Irritable Bowel Syndrome.
Despite there being no clearcut advantages, one of the most common recommendations in IBS management is to increase the amount of dietary fibres. In some IBS patients fibres have a deleterious effect on pain and bloating. It has been shown that butyrate can increase colonic sensitivity in rats. Our purpose is to study whether butyrogenic fibres can modify rectal sensitivity and symptoms in IBS and healthy control through a modification of colonic flora.
About 10% of the population in western countries suffer from abdominal pain and change of bowel habits - known as the irritable bowel syndrome. The patients suffer from low quality of life and they are often not well taken care of within the public healthcare system. They often feel frustrated and seek both their family doctors, specialists and alternative medicine for help. Many patients feel they do not know enough about their disease, and the uncertainty may enhance bowel symptoms. We want to evaluate the effect of patient information and education in these patients.
This is placebo-controlled study of three rifaximin doses in patients with DIBS. Subjects will be randomized to receive daily doses of placebo BID, rifaximin 275 mg BID, rifaximin 550 mg BID, or 1100 mg BID for 14 days. These four groups will subsequently receive an additional two weeks of placebo for a total of 4 weeks of treatment. A fifth group of subjects will receive rifaximin 550 mg BID for a period of 28 days. Subjects who successfully respond to treatment at the end of the 28-day Treatment Phase will be followed in a Post-treatment Phase that includes study visits during Weeks 6, 8, 12 and 16. Subjects who relapse during the Post-treatment Phase will be discontinued from the study.
The purpose of the study is to investigate whether renzapride will help alleviate the symptoms associated with constipation predominant irritable bowel syndrome in female patients.
We have recently shown that the majority of patients with irritable bowel syndrome (IBS) have an abnormal lactulose breath test to suggest the presence of bacterial overgrowth of the small intestine. In open label and double blind treatment of IBS subjects with antibiotics, a dramatic improvement in clinical symptoms are observed. In these studies, the antibiotic chosen was neomycin, which is noted to have an efficacy of 20-25% in normalizing the lactulose breath test. A more efficacious antibiotic is needed. Therefore the aim of this study is to determine the efficacy of rifaximin in normalizing the lactulose breath test in IBS subjects with concomitant improvement in clinical symptoms.
- The primary objective of this trial is to compare the dose-ranging pharmacodynamic effects of orally administered placebo, and 100 and 1000 ug qd of MD-1100 Acetate on gastrointestinal transit in patients with C-IBS. - The secondary objectives of this trial are: 1. To compare the dose ranging pharmacodynamic effects of placebo, and 100 and 1000 ug MD-1100 Acetate once daily on time to first bowel movement after first drug intake. 2. To describe and summarize the effects of placebo, and 100 and 1000 ug MD-1100 Acetate once daily on stool frequency, stool consistency, ease of passage and sensation of incomplete evacuation during the Treatment Period relative to Baseline.
Acute Bacterial dysentery leads to chronic symptoms of disturbed bowel habit in a minority of individuals. This condition known as post infectious irritable bowel syndrome (PI-IBS) remains poorly understood. This could allow material in the bowel to reach deeper tissues of the bowel wall leading to inflammation and changes in muscle and nerve function. This is also early evidence that genetic programming of people with PI-IBS prevents them from turning off inflammation once it begins. Literature suggests that IBS may develop at greater rates in individuals with pro-inflammatory genotype and that these individuals may be at increased risk of inflammatory bowel diseases (IBD).
