Ulcerative colitis (UC) is a chronic inflammatory digestive (IBD) disease medically treated with corticosteroids, aminosalicylates, immunomodulators, and biologics. Almost one third of UC patients will require surgical interventions because of fulminant colitis, dysplasia, cancer, or medical refractory diseases. Restorative proctocolectomy with ileal pouch-anal anastomosis (IPAA) is the current standard surgical intervention. Anastomotic leak, pouch failure, pelvic sepsis, and pouch ischemia can occur after the procedure, but the most common long-term complication is pouchitis, an idiopathic inflammatory condition involving the ileal reservoir. Symptoms of pouchitis are increased stool frequency, urgency, incontinence, bloody stools, abdominal or pelvic discomfort, fatigue, malaise, and fever. The prevalence of pouchitis ranges from 23 to 46 %, with an annual incidence up to 40 %. Though the majority of initial cases of pouchitis are easily managed with a short course of antibiotics, in about 5 to 15 % of cases, inflammation of the pouch becomes chronic with very few treatments available.
Fecal microbiota transplantation (FMT) is a novel therapy to transfer normal intestinal flora from a healthy donor to a patient with a medical condition potentially caused by disrupted homeostasis of intestinal microbiota or dysbiosis. FMT has been widely used in refractory Clostridium difficile infection (CDI) and recently it has gained popularity for treatment of inflammatory bowel disease (IBD). Previous studies suggested that manipulating the composition of intestinal flora through antibiotics, probiotics, and prebiotic achieved significant results for treating acute episodes of UC-associated pouchitis. However, currently there is no established effective treatment for chronic antibiotic dependent pouchitis. Our project aims to evaluate the delay of relapse in chronic recurrent pouchitis after FMT versus sham transplantation.

4.2. INCLUSION CRITERIA
Subjects must satisfy the following criteria to be enrolled in the study:
4.3. NON-INCLUSION CRITERIA
Subjects who meet any of the following non inclusion criteria could not be enrolled in this study:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).
Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.
Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.
Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.
Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.
Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.
The number of neutrophils, white blood cells that help fight infection, in a given amount of blood. Too few raises the risk of infection.
It is a count, not a percentage of the white cells. Limits are written in units that mean the same: ≥ 1.5 × 10⁹/L is ≥ 1,500 per mm³ (µL). Each lab has its own reference range.
The human immunodeficiency virus, which weakens the immune system.
Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.
A drug or device being studied in a clinical trial.
It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.
A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.
