Brief Summary

Irritable bowel syndrom (IBS) is a common chronic gastrointestinal disorder that affects 10-20% of the world population. The prevalence of IBS in Norway is between 8% and 25%. The pathophysiology of IBS is incompletely understood, and there is no effective treatment for this condition. Imbalance (dysbiosis) of the gut microbiome has been found in patients with IBS. In the absence of effective method to restore the dysbiosis, transplantation of a microbiome from healthy individuals with well-functioning gut (FMT) to those with IBS has been performed. Two randomized double blind placebo-controlled (RCT) studies have been published recently. Whereas it was reported in one study that FMT reduced symptom and improved quality of life in patients with IBS, FMT had no effect in the other study. In order to clarify these contradictory results, a new RCT study that enrolled larger number of patients is required. In this study, the investigators intend to recruit 170 IBS patients from those attending outdoor clinic at Stord hospital in a randomized, double blind placebo trial. A single healthy donor with well-characterized microbiome is going to be used. The effects on symptoms, quality of life, fatigue as well as dysbiosis before and after FMT are going to be investigated. The possible mechanisms behind the effects if any of FMT such as changes in intestinal stem cells, enteroendocrine cells and local immune defense shall be also investigated. The patients are going to be randomized either to placebo (own faces), 30 g or 60 g of the donor faces in ratio 1:1:1.

Outcome Measures

Primary Outcomes (5)

  • Global improvement in IBS symptoms as assessed by IBS Symptom Severity Scale (IBS-SSS)

    IBS-SSS is a visual assessment scale (VAS) rating from 0 to 100, with total scores ranging from 0 to 500. Lower scores indicate improvement.

    3 months.

  • Global improvement in IBS symptoms as assessed by Birmingham Symptom scale questionnaire

    This questionnaire consists of 11 question. measured on a six-point Likert scale ranging from 0 to 5. Lower scores indicate improvement.

    3 months.

  • Quality of life as assessed by IBS quality of life (IBSQoL) questionnaire

    IBSQoL consist of 34- questions measured on a five-point Likert scale ranging from 0 to 5. Higher scores indicate improvement.

    3 months

  • Quality of life as assessed by Short form of Nepean Dyspepsia Index (SF-NDI) questionnaires

    SF-NDI is a five-point Likert scale ranging from 0 to 5. Lower scores indicate improvement.

    3 months

  • Fatigue as assessed by: Fatigue Assessment Scale (FAS) questionnaire

    FAS is a five-point Likert scale ranging from 0 to 5. Lower scores indicate improvement.

    3 months

Secondary Outcomes (1)

  • Stool microbiota changes as assessed by the Dysbiosis index (DI)

    3 months.

Other Outcomes (1)
