The Role of Secondary Bile Acids in Intestinal Inflammation
Ulcerative ColitisPouchitisThe cause of Inflammatory bowel disease (IBD) is unknown, but intestinal bacteria-involved in the production of molecules that impact health-are widely accepted to play a key role. A significant proportion of IBD patients with pouches (surgically created rectums after the diseased colon is removed) continue to have inflammation similar to their previous disease. Only a few microbes are known to have the capability to modify primary bile acids (PBAs) made by the liver to secondary bile acids (SBAs). SBAs are some of the most common metabolites in the colon and play key roles in several diseases. In this study the investigators will investigate if ursodeoxycholic acid (UDCA) may reduce inflammatory markers and improve quality of life (as assessed by validate survey) in those subjects with active antibiotic refractory or antibiotic dependent pouchitis.
the Prophylaxis of Recurrent Pouchitis After Fecal Microbiota Transplant in UC With Ileo-anal Anastomosis...
PouchitisUlcerative 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.
GM-CSF, Fosfomycin and Metronidazole for Pouchitis in Ulcerative Colitis Patients After Restorative...
PouchitisThis study will examine whether the application of GM-CSF, fosfomycin and metronidazole locally in the pouch is safe and effective in the treatment of pouchitis for patients with ulcerative colitis, and whether treatment changes the microbiome of the pouch.
Fecal Microbiota Transplantation for Pouchitis
PouchitisThis is a randomized double-blind placebo controlled trial involving a single centre (McMaster University) recruiting patients from Hamilton, ON and the surrounding regions, to evaluate whether fecal microbiota transplantation once weekly for six weeks increases the remission rate compared to placebo in patients with active pouchitis.
Prospective Dietary Therapy Using Crohn's Disease Exclusion Diet for Ileal Pouch Anal Anastomosis...
PouchitisCrhon's Disease Like of the PouchRestorative proctocolectomy with ileal pouch-anal anastomosis (IPAA) is the surgical treatment of choice for patients with ulcerative colitis (UC) who require surgery. Inflammation of the ileal pouch (pouchitis) occurs in up to 60% of pouch patients. Although, pouchitis patients are former UC patients, the disease occurs in the small intestine, similarly to Crohn's disease (CD). Further, the disease can be clinically similar to CD, involving the proximal gastro-intestinal tract and causing strictures, fistula, or perianal disease. The Crohn's Disease Exclusion Diet (CDED) reduces exposure to all the components identified in rodent models as well as two components that are highly suspect but have not been investigated in models. The diet also provides dietary components that may favor species (especially SCFA producers) which appear to be deficient in CD. The investigator therefore aims to examine the microbial, mucosal and immunological changes of the pouch during one year post IPAA, and examine the impact of the CDED on disease activity and dysbiosis in a cohort of adults suffering from active pouchitis.
Inflammatory Bowel Diseases (IBD) Cannabis Registry
Crohn DiseaseUlcerative Colitis2 moreThe inflammatory bowel diseases (IBDs), ulcerative colitis (UC) and Crohn's disease (CD), are characterized by lifelong relapsing-remitting gastrointestinal inflammation, with symptoms of abdominal pain, diarrhea, and rectal bleeding during active disease. Medical therapy reduces intestinal inflammation and ameliorates symptoms. Medical cannabis has recently been added to the arsenal of symptom-reducing measures in IBD. Though the efficacy of THC and CBD have been established as the two most dominant ingredients of cannabis, the rest of the plant phytochemicals are unknown, and effects on patients are not yet determined.
Assessment of Patients With Acute Pouchitis Treated With Antibiotics
PouchitisUlcerative ColitisThe purpose of this study is to evaluate the reliability and responsiveness of symptoms, endoscopic, and histological items for assessing pouchitis disease activity in patients undergoing standard of care (SOC) antibiotic therapy for treatment of pouchitis, in order to develop a novel pouchitis disease activity index.

Chronic PouchitisPouchitisThe purpose of this research study is to assess the safety and efficacy of fecal microbiota transplant (FMT) in the treatment of chronic pouchitis.

Safety and Efficacy of Fecal Microbiome Transplantation (FMT) in the Treatment of Antibiotic Dependent...
PouchitisAntibiotic dependent pouchitis (ADP) is predestined to benefit from FMT, since bacterial dysbiosis, which can only be controlled with antibiotics, appears to be the major driver of the clinical symptoms. This is a proof of concept randomized placebo controlled trial, in which 50% of the patients will receive FMT and 50% will receive a placebo FMT. Additionally the trial offers an open label extension period.
