Many patients with irritable bowel syndrome (IBS) do not experience adequate symptom relief with current treatments. The pathophysiology of IBS is diverse, controversial and not completely understood. The next disruptive frontier would be to find a cure where the effect is predictable and lasting. The study groups phase 2 pilot trial was the first indication of a possible benefit from treating IBS with fecal microbiota transplantation (FMT) (Number needed to treat only five) (Fecal microbiota transplantation versus placebo for moderate-to-severe irritable bowel syndrome: a double-blind, randomized, placebo-controlled, parallel-group, single-centre trial he Lancet Gastroenterology and Hepatology 2018). Additional results from the same trial show that the treatment response may be predicted (unpublished data), and that the pathophysiologic mechanisms behind the treatment response also can be identified (Effects of fecal microbiota transplantation in subjects with irritable bowel syndrome are mirrored by changes in gut microbiome, Gut Microbes 2020). This study is the first phase 3 trial of FMT for IBS worldwide. The hypothesis of the trial is that donor FMT is more effective than placebo FMT in treating IBS, with little adverse events or complications. Patients ≥18 years with IBS are enrolled at five Norwegian Hospitals in this double blind randomized, placebo controlled, parallell-group multi center trial. Participants are randomized to FMT from a healthy donor (intervention group), or their own feces (placebo group). The primary outcome is the proportion of patients with ≥75 points decrease in the Irritable bowel Symptom Severity score 90 days after treatment.
The purpose of this research is to assess if a new digital app version of a self-help intervention for Irritable Bowel Syndrome (IBS), is an acceptable and effective treatment for improving the overall quality of life in patients with IBS.
The pathophysiology of Irritable bowel syndrome (IBS) is multifactorial involving complex interplay of altered intestinal permeability, mucosal immune activation, visceral hypersensitivity and gut dysbiosis. Although the exact triggers for these pathological changes in IBS are not clear but diet might play an important role. In fact, several studies have reported improvement in gastrointestinal symptoms on a diet low in FODMAPs (LFD) in patients with IBS, specifically in diarrhea predominant IBS (IBS-D). However, the mechanism of action of LFD is not well understood.
A remote study to find out if a mobile phone application (HealthMode Stool) can serve as a useful tool to track and characterize daily bowel movements. The application provides participants with a single place to record their bowel movements either as a part of their general health self-monitoring, or because they may be dealing with a bowel movement condition. The minimal study duration is 1 month, and participants can continue using the application up to 2 years.
LIN-MD-66 is a Phase 3 open-label study with 24 weeks (Functional Constipation participants) or 52 weeks (Irritable bowel syndrome with constipation participants) of linaclotide exposure that will enroll pediatric participants (6-17 years of age) with FC or IBS-C who completed study intervention in studies LIN-MD-62, LIN-MD-63, orLIN-MD-64 based on the individual study criteria.
The investigators will perform a multicenter, 2:1 randomized, double-blinded, placebo-controlled trial of AMR in patients with diarrhea predominant-IBS (IBS-D) diagnosed according to Rome III criteria and the IBS-QOL questionnaire. Central supply and quality control of donor material will be used to control bias. Primary endpoint is improvement of IBS-SSS (Severity Score System) compared to baseline. Secondary endpoints include changes in IBS-QOL, short term safety and one year follow up to control long term effects, safety and changes in and acceptance of donor microbiome after AMR using16S rDNA sequencing and quantitative diversity analysis.
Selective serotonin reuptake inhibitors increase the level of serotonin. This study will use functional magnetic resonance imaging to examine how subjects with, and without, irritable bowel syndrome patients respond to serotonergic stimulation. Brain activation during emotional and arithmetic tasks and during visceral pain will be measured after serotonergic stimulation using the oral administration of Escitalopram (10 mg). The investigators will further integrate background parameters of the irritable bowel syndrome subjects and healthy controls (such as microbiota composition, genetic markers of serotonergic and inflammatory pathways, intestinal permeability, state of mood and visceral sensitivity) with the responses to the various challenges on the level of functional brain imaging. These responses may reveal a 'footprint' of the individual gut-brain axis function. Analyses of these individual footprints in multiple subjects with and without irritable bowel syndrome may reveal biosignatures characterising certain groups of patients according to specific gut-brain signalling response patterns. These biosignatures may be used to develop an individualised treatment algorithm for irritable bowel syndrome therapy.
This is an exploratory neurophysiological study that will determine the impact of non-invasive brain stimulation on autonomic regulation, with a focus on gastrointestinal function. These studies should provide a basis for future brain-based neurotherapeutic strategies in patients with functional GI disorders.
The first aim of the study is to investigate the prevalence of persistent gastrointestinal symptoms and compliance with gluten-free diet and the intake of FODMAP in adult celiac patients. A web-based survey wil be performed and thereafter a randomized controlled trial to test the effect of a FODMAP reduction in patients with celiac disease with irritable bowel-like symptoms.
