Fecal Microbiota Transplantation for Irritable Bowel Syndrome Associated Food Intolerance

Fecal Microbiota Transplantation for Irritable Bowel Syndrome Associated Food Intolerance

Previous studies have shown that stool transplantation (FMT) have positive effect in symptoms for some patients with irritable bowel syndrome (IBS). Studies have shown that it is possible by FMT to reverse the microbiome of the recipient's intestine in the direction of the microbiome of the donor. The effect on eating habits for engraftment of microbiome by FMT is unknown.

The purpose of this study is to investigate whether FMT relieves FODMAP diet extension without worsening intestinal symptoms in IBS patients.

This is a plasebo controlled study in which we study the effect and safety of FMT in patients who have IBS and have used FODMAP diet. FMT is assessed by colonoscopy route and therafter the patietns receive twice FMT enema from healthy donor or plasebo..

Inclusion Criteria:

• Adults, age 18-75 years, knowledge of the Finnish language
• IBS patients have been diagnosed with the Rome IV- criteria, all IBS-subtypes will be accepted to the trial
• The patient must consume low FODMAP diet to control IBS symptoms
• Patient must sign the informed consent

Exclusion Criteria:

• Diagnosed allergies to food components in the study dietary protocol
• Pregnancy and breastfeeding
• Antibiotic treatment less than three months prior enrolment
• Faecal incontinence, i.e., inability to retain enema
• Abuse of drugs, alcohol or medications
