Detailed Description
Study Description Brief Summary: Two hundred patients are randomized1:1:1:1 into placebo (own feces), receiving 90 g fecal transplant from donor A, donor B or donor C. The fecal transplant is administered to distal duodenum via working channel of a gastroscope. The patients shall complete 5 questionnaires measuring symptoms, fatigue, quality of life and diet intake at the baseline and at the end point of the trial and provid a feces sample at the baseline, and at 3, 6 and 12 months after FMT. Dysbiosis and fecal bacterial are determined by using 16S rRNA gene PCR DNA amplification/probe hybridization covering regions V3-V9.
Detailed Description: Patients: Two hundred patients who fulfil Rome IV criteria for irritable bowel syndrome (IBS) shall be included in the study. All IBS subtypes shall be included with the exception of IBS-U. Donors: The investigators have selected 3 donors (A, B and C) according to the criteria used in their previous randomised double-blind, placebo-controlled study. These criteria included: being a healthy man or woman with no history of disease and no use of medications, aged 20-50 years, being a non-smoker, and exercising regularly. They were borne by vaginal delivery and breastfed. They were treated only a few times with antibiotics during their life. They are screened according to the European guidelines for donors for FMT. Before they are accepted as donors, the bacterial profile and dysbiosis were analysed in a faecal sample using the GA-map dysbiosis test, with a dysbiosis index (DI)= 1, indicating normobiosysis. Their feces shall be tested every third month during the trial to exclude communicable disease. Donor A is a male aged 41 years, donor B is a female aged 31 and donor C is a male aged 35.
Protocol: The patients are randomized 1:1:1:1 into placebo (to receive their own feces), to receive 90 g fecal transplant from donor A, from donor B or donor C. Fecal transplant is administered to the distal duodenum via the working channel of a gastroscope. The patients shall complete 5 questionnaires and deliver fecal samples at the baseline, and at 3 , 6 , and 12 months after FMT. Feces collection, preparation and administration: Faeces from both the donors and patients shall be collected and stored at - 80ºC. Frozen donor faeces shall be thawed in the refrigerator at 4ºC, and each 30 g portion is dissolved in 30 mL of 4ºC cold 0.9% sterile saline. The dissolved stool is administrated to the patients, after overnight fast, through the working channel of a gastroduodenoscope in the pars descendens of the duodenum always distal to the papilla of Vater. Questionnaires
- IBS Symptom Severity Scale (IBS-SSS).
- Birmingham Symptom Scale.
- Fatigue Assessment Scale (FAS).
- IBS-quality of life (IBSQoL) Questionnaire.
- Semi-quantitive Food Frequency Questionnaire (FFQ)
- Bristol Stool Form Scale
Bacterial analysis: Fecal bacterial analysis is performed using a 16S rRNA gene PCR DNA amplification/probe hybridization technique covering regions V3-V9. DNA extraction is done by using magnetic beads. DI is based on 54 DNA probes targeting more than 300 bacterial strains based on their 16S rRNA sequence in seven variable regions (V3-V9). Fourty-nine bacterial probes are species specific, 19 detect bacteria at the genus level, and 9 probes detect bacteria at higher taxonomic levels. Probe labelling is by single nucleotide extension and hybridization to complementary probes coupled to magnetic beads, and signal detection by using BioCode 1000A 128-Plex Analyser (Applied BioCode, Santa Fe Springs, CA, USA). A DI above 2 shows a microbiota profile that differs from that of the normobiotic reference collection (DI 1-2: non-dysbiosis, DI: moderate, DI 4-5: severe dysbiosis).

Change in IBS-SSS total score
Time Frame: 12 months after FMT
|
Irritable bowel syndrome-symptom severity score (IBS-SSS) is a visual analogue scale questionnaire with a maximum score of 500 points.
A decrease in total score by ≥50 points is considered as a response.
