简要总结
The purpose of thus study is to determine if faecal microbiota transplantation will result in improvement in clinical outcomes in patients with irritable bowel syndrome.
详细描述
- Background
Irritable bowel syndrome (IBS) is a chronic, debilitating, functional gastrointestinal disorder with estimated population prevalence in Europe between of 10 -15% (Ford et al). These symptoms can be debilitating and lead to a significant reduction in quality of life particularly in the more severely affected.
Alterations in the function and composition of the gut microbiota are increasingly being implicated as potential aetiological factors. (Collins et al). One of the strongest indictors for this concept is the significantly increased risk of developing IBS after an episode of acute gastroenteritis. Prospective studies have demonstrated that between 3- 36% of enteric infections lead to new, persistent IBS symptoms. (Gwee at al.,Neal et al) A number of studies have demonstrated that the diversity, stability and metabolic activity of the gut microbiota are altered in IBS patients compared with healthy individuals (Jeffrey et al). Although a distinct microbial signature has not been identified for IBS, several studies have shown a gut microbial composition enriched with Firmicutes together with a reduced abundance of Bacteroides (Jeffery et al, Rajilic-Stojanovic et al).
Faecal microbial transplantation (FMT) has proven to a safe, inexpensive and effective treatment for recurrent Clostridium difficile infection achieving up to 90% cure rates in some studies with a very good side effect and adverse event profile (van. Nood et al.). In this study the investigators wish to investigate whether restoring healthy gut microbiota profiles, using stool from healthy donors, will lead to improved clinical outcomes for patients with IBS.
Autologous fecal microbiota transplant using re - infusion of the participants own faeces has been previously been used as a placebo in studies using FMT (Vrieze et al) 2. Study Design

结局指标
主要结局
Global Assessment of relief of IBS symptoms.
时间窗: 8 weeks
This assessment will be obtained by defining the response (Yes or No) to the following question. "Please consider how you felt in the past week in regard to your IBS, in particular your overall well-being, and symptoms of abdominal discomfort or pain, bloating or distension and altered bowel habit .Compared to the way you usually felt before the beginning of the trial, have you had adequate relief of your IBS-symptoms?"
次要结局
- Quality of life(8 weeks)
- Primary symptoms of IBS(8 weeks)
- Safety as measured by occurrence of adverse events(8 weeks)
- Depression and Anxiety(8 weeks)
