Filter by:The study aims to investigate how to give the diagnosis of Irritable Bowel Syndrome. The investigators compare two parallel groups of primary care patients, in the age of 18-50 years with gastrointestinal complaints where the GP suspects IBS. All included patients fulfil international diagnostic criteria (ROME III) and have no danger signals. Group 1: The diagnosis is based on the diagnostic criteria and few blod tests Group 2: The diagnosis is a diagnosis of exclusion after investigations with extended blod tests, examination for milk- and gluten intolerance, stoll for ova and parasites and scopy of the intestine. After receiving the diagnosis of Irritable bowel syndrome all patients are informed about the condition. The investigators follow the patients for 1 year. The investigators hypothesis is that the two investigation programmes (group 1 and 2)are equal with respect to the patients´ quality of life, symptoms and satisfaction and also with respect to finding of organic diseases.
The study aims to investigate the effect of probiotics on IBS-patients symptoms compared to placebo, when given for 6 months. By draw the investigators give IBS patients, in the age of 18-50 years, capsules with either probiotics or placebo. The patients are to take 2x2 capsules / day for 6 months. The patients are followed for 1 year. They are seen after 3, 6 and 12 months, and are followed by means of monthly letters. The capsules contain 3 different probiotic strains - Lactobacillus paracasei ssp paracasei F19, Lactobacillus acidophilus La5 and Bifidobacterium Bb12. The dose is 2 x 109 - 10 x 109 CFU/capsule. The hypothesis is, that there is a clinical difference between the group receiving probiotics and the group receiving placebo.
Study is to assess the effectiveness of TC-6499 in the treatment of constipation predominant IBS patients over a 28-day period.
Purpose: To evaluate the efficiency of Irritable Bowel Syndrome (IBS) patients treatment with the H1-receptor antagonist ebastine. Design: Double blind randomized placebo controlled trial. IBS patients receive a 12-weeks treatment with ebastine 20mg once daily or placebo (1:1 randomization). End points: End point is the effect of treatment on clinical symptoms and visceral hypersensitivity which will be evaluated with a barostat test.
Irritable bowel syndrome is a common digestive disorder worldwide. However, there is no effective treatment of irritable bowel syndrome. Visceral pain thresholds in response to stress are lower in patients with IBS compared to healthy volunteers, but the triggers to visceral hypersensitivity remain largely unknown. Animal models suggest roles for both host immune response and intestinal bacteria in the induction of visceral hypersensitivity. For instance colorectal distension increased in association with an alteration in bacterial flora induced by antibiotic therapy, which suggest a relationship between bacterial gut content and visceral afferent processing. Intestinal bacteria play a significant role in inducing IBS. Clinical studies have shown that manipulation of the commensal microbiota with probiotic bacteria, in particularly preparations that contain bifidobacteria, can alleviate IBS symptoms. Serotonin (5-HT) plays a crucial role in the regulation of gastrointestinal physiology and alterations in mucosal serotonin signaling is a possible mechanism of altered function and sensation in patients with IBS. Impairment of serotonin reuptake transporter (SERT) expression and function may also play a role in IBS. The investigators hypothesise that bacteria modulate sensory afferent and serotonin signaling necessary for visceral sensation and that these pathways can be targeted for therapy of IBS using probiotic bacteria. The first part of this study will be a cross-sectional study comparing the colonic microbiota and SERT polymorphisms in IBS patients and healthy controls. The second part will be an open-label pilot study to assess the effects of oral probiotic bacteria in visceral hypersensitivity and mucosal microbiota in patients with IBS. Clinical response will be assessed based on IBS symptom score and rectal sensitivity, and changes in mucosa microbiota will be measured using 454 pyrosequencing. This proposal will provide novel data on gut microbiota in Asian IBS patients, and explore the mechanisms underlying visceral hypersensitivity to direct future targeting of therapy in IBS.
Currently, the pathophysiology of Irritable bowel syndrome( IBS) remains unclear . The purpose of this study is want to investigate the immunological changes in the children with IBS.
The purpose of this study is to determine the efficacy, safety, and tolerability of different doses of JNJ-27018966 (eluxadoline) compared with placebo in the treatment of patients with irritable bowel syndrome with diarrhea (IBS-d).
To determine the effect of cultura probiotic yoghurt on number of responders to treatment during 8 weeks of treatment in comparison to placebo. To determine the effect of cultura yoghurt on change in total score of (IBS) irritable bowel syndrome severity index during 8 weeks of treatment in comparison to placebo in IBS out patients.
This protocol matches child subjects with peer mentors of similar age who have learned to function successfully with a chronic pain disorder. The trained mentors will present information to the subjects in a supervised and monitored interaction via telephone and computer for 2 months and encourage participation in skill-building programs. Children will be tested for improvement in pain and functioning at 2 months and again at 4 months to see if improvements persist. The investigators hypothesize that children who received peer mentor support will show more improvement in pain and functioning at 2 and 4 months into treatment than those in a control group who do not receive mentor support.
The rapid diarrhea that patients experience who have diarrhea occurring after eating specific foods may be causing a "physiologic gastric dumping syndrome". This means that rather than the food being kept in the stomach for normal digestion, it rapidly goes into the small intestine and diarrhea occurs. This study is designed to measure how fast the food empties from the stomach when a person with this problem consumes a "regular diet", compared to a meal with a "triggering substance". Each participant will swallow a radio frequency capsule that with the different meals that will show how fast the food is traveling through the intestines in the different situations.
