Active clinical trials for "Irritable Bowel Syndrome"

Non-constipated irritable bowel syndrome is a common disorder that may be related to small intestinal bacterial overgrowth. Saccharomyces boulardii CNCM I-745 is a probiotic yeast that has proven efficacy for the treatment of acute gastroenteritis and antibiotic-associated diarrhea. However, its efficacy for the treatment of diarrhea-predominant irritable bowel syndrome with small intestinal bacterial overgrowth has not been assessed. Hence, an exploratory randomized, open label trial comparing the efficacy and safety of Saccharomyes boulardii CNCM I-745 plus diet administration versus diet administration only for 15 days among adult patients with the aforementioned condition was conducted.

The study aims to test the effect of Ashtanga yoga on well-being in patients with irritable bowel syndrome (IBS). The intervention comprises group sessions on the Ashtanga school of yoga. Participants are recruited from primary care and measurements on well-being and IBS symptoms are conducted at pre-treatment, post-treatment and 6-month follow-up.

Probiotics efficacy is mainly assessed by subjective endpoints such as the FDA responder rate or global relief, which partly explain contradictory results obtained in clinical trials with probiotic bacteria. Objective biomarkers of IBS will allow to measure the efficacy of probiotics. In the case of IBS-C, serum resolvin-D1 appears to be an interesting candidate due to its non-invasive and discriminating character compared to a healthy population. It is, inversely correlated with the severity of symptoms. Resolvin-D1 modulates the duration and intensity of inflammation by regulating the transcription of cytokines, chemokines and their receptors as well as other proteins involved in inflammation. Resolvin D1 could serve as a predictor of probiotic response based on its baseline value.

The double-blinded placebo-controlled study compares the effect of fecal microbiota transplantation vs. Anaerobically Cultivated Human Intestinal Microbiota (ACHIM) or placebo (own feces) on manipulating the gut microbiota in patients with diarrhea-predominant irritable bowel syndrome (IBS).

This study aimed to assess the impact of consumption of COMBO, a combination product of two Bifidobacterium longum strains, on stress, mood and bowel symptoms in adults with Irritable Bowel Syndrome (IBS).

The aim of the study is to evaluate the effects of a specific Cognitive Behavioral treatment protocol for patients with IBS used in routine care at a gastroenterology unit in Stockholm. The research question is whether the treatment has the same effects in routine care as it has had in efficacy studies. The treatment is given by licenced psychologists (with CBT training) face-to-face in groups of 4-7 participants and lasts for ten sessions (ten weeks, normally).

Rationale: Irritable Bowel Syndrome (IBS) is functional gastrointestinal disorder that affects a large number of people. To date, no adequate treatment is available. This is partially due to the heterogeneity of the patients and the complicated pathology in which not all mechanisms are understood. Based on results of in vitro screening within the IBSQUtrition project, we selected promising dietary supplements for validation of their potential beneficial effects on the microbiota of IBS patients. Objective: The primary objective is to determine the bifidogenic effects of a 4-week intervention with one of four dietary supplements (Chondroitin sulfate, NOVELOSE® 3490, and Pea Fiber, and Lactium®) in IBS patients. The secondary objective is to determine the effects of the same intervention on fecal microbiota composition and SCFA concentration, IBS-related complaints, Quality of Life, and stool frequency and consistency in IBS patients. Study design: a double-blind, randomized, placebo-controlled trial with five parallel arms. Study population: 70 adult (18-65 yrs) IBS patients Intervention: 4-week intervention period with five parallel arms: 1) Chondroitin sulfate, 2) NOVELOSE® 3490, 3) Pea Fiber, 4) Lactium®, and 5) Placebo supplement (Maltodextrin control), during which the study participants consume the respective supplement twice per day. Main study parameters/endpoints: The main study parameter is the (relative) abundance of fecal Bifidobacterium. The secondary study parameters are fecal microbiota composition and Short-Chain Fatty Acids (SCFAs) concentration, stool frequency and consistency, IBS-related complaints, and Quality of Life (QoL). Nature and extent of the burden and risks associated with participation, benefit and group relatedness: Study participants have to invest about 7.4 hours of their time in this study mainly to complete several questionnaires (short daily questionnaire, longer questionnaires at two occasions), which is conveniently all possible from home. On two occasions they have to collect stool (transported via courier to the research facility). They have to comply to consume a commercially available supplement twice daily for four weeks. There are limited risks for the study participants.

The purpose of this research is to assess if a new self-help app for IBS is an acceptable and effective intervention for improving the overall quality of life in patients with Irritable Bowel Syndrome.

Background. Abdominal distention is produced by an abnormal somatic postural tone. We developed an original biofeedback technique based on electromyography-guided control of abdominothoracic muscular activity. In a randomized, placebo-controlled trial we demonstrated the superiority of biofeedback over placebo for the treatment of abdominal distention. However, the technique is technically complex and unpractical. Aim. To prove the efficacy of a simplified biofeedback technique for the treatment of abdominal distension. Selection criteria. Visible abdominal distension after meal ingestion; patients are able to identify the offending meal. Intervention. Patients will be randomized into biofeedback in placebo groups.Three sessions of either biofeedback or placebo intervention will be performed 30 min after ingestion of the offending meal during the first 3 weeks of the intervention period. Biofeedback: patients will be taught to control abdominal and thoracic muscular activity by providing a visual display of the abdominal and thoracic perimeter; specifically, they will be instructed to reduce the abdominal perimeter (girth); patients will be instructed to perform the same exercises before and after breakfast, lunch and dinner during the 4-week intervention period. Placebo: abdominal and thoracic perimeter will be recorded but not shown to the patient and a pill of placebo containing 0.5 g glucose will be administered; patients will be instructed to take a pill of placebo before breakfast, lunch and dinner during the 4-week intervention period. Primary Outcome Measure: Effect of the probe meal on the activity of thoraco-abdominal muscles (intercostals, external oblique, internal oblique, upper rectus, lower rectus) measured by electromyography before and after the probe meal. The response to the probe meal will be measured before and after treatment. Secondary Outcome Measures: Effect of the probe meal on sensation of abdominal distension measured by 0-6 scales after the probe meal. Changes in girth produced by the probe meal measured using a non-stretch belt placed over the umbilicus before and after the probe meal. Sensation of abdominal distension measured by 0-6 scales after each meal (breakfast, lunch, dinner) over a 7-day clinical evaluation period before and during the 4th week of the intervention.

Background: The combination of Lactobacillus fermentum and Lactobacillus delbrueckii (Lactobacillus LB) has proven to be effective and safe for the treatment of acute diarrhea in children. Also, a clinical trial in adult patients with chronic diarrhea, showed a reduction in the number of daily stools. However, the evidence is not enough regarding the efficacy and safety of Lactobacillus LB for treatment of patients with irritable bowel syndrome with predominance of diarrhea (IBS-D). Justification for this study: Lactobacillus LB could be a promising treatment for patients with IBS-D; nevertheless, the scientific evidence in this context is limited and it is not recent. Therefore, is necessary to explore the efficacy and safety of Lactobacillus LB in patients with IBS-D according to Rome IV criteria. Hypothesis: Lactobacillus LB is useful to decrease the frequency and improve the stools consistency of patients diagnosed with IBS-D by Rome IV criteria. Primary Outcome: To compare the treatment with Lactobacillus LB at two different doses: a) 20,000 million / day, vs. b) 10,000 million / day; and to determine if one of them is better than c) placebo, to decrease the frequency (weekly average of the number of stools/day) in patients diagnosed with IBS-D by Rome IV criteria. Design of the study: Clinical trial, randomized, double-blind, placebo-controlled. Keywords: irritable bowel syndrome with diarrhea, Lactobacillus LB, treatment, efficacy, safety.
