Ussing Experiments to Evaluate the Role of Medication-induced Microscopic Colitis
Microscopic ColitisMedication use, especially NSAIDs and PPIs, prior to diagnosis is considered a risk factor for MC development. However, the exact pathophysiological mechanism is unclear. It is hypothesized that NSAIDs, PPIs, and SSRIs may have an effect on the colon permeability, due to an idiosyncratic reaction which results in a local immune response. MC patients are considered to be susceptible hosts, prone to react on administration of abovementioned drugs. In order to test this hypothesis and to generate new insights in the pathophysiology of MC, we want to perform an Ussing chamber experiment using fresh colon tissue samples. The primary objective is to assess ex vivo the effect of NSAIDs and PPIs on epithelial permeability of colon biopsy specimens of MC and non-MC patients, using the Ussing chamber system
Golimumab (GLM) Dose Optimisation to Adequate Levels to Achieve Response in Colitis
ColitisGLM dose Optimisation to Adequate Levels to Achieve Response in Colitis (GOAL-ARC). A nationwide multi-centred randomised controlled trial (RCT) investigating the use of GLM dose adjustment in ulcerative colitis (UC). The primary objective is to ascertain if dose adjustment of GLM based on GLM drug levels and FCP levels results in higher response and remission rates than standard SmPC dosing.
Human Umbilical-Cord-Derived Mesenchymal Stem Cell Therapy in Active Ulcerative Colitis

Restoration of the Microbiome Through Superdonor Selection
Ulcerative ColitisThe AIM of this study is to investigate whether the FMT success rate in active UC patients can be increased by intensive donor pre-screening, anaerobic preparation of the FMT and by repeated FMT. The investigators will start a national multi-centre double-blind randomized sham-controlled trial in April 2017 at 6 hospitals in Belgium and 2 in The Netherlands. They will randomly allocate 108 patients with active ulcerative colitis (Mayo score 4-10, endoscopic Mayo score 2 or 3) in a 1:1 ratio, using a pre-established randomization list, to either 'superdonor' faecal microbiota transplantation or autologous fecal microbiota transplantation (=sham). Each patient will receive 4 FMT's. At baseline FMT will be performed during sigmoidoscopy. At week 1, 2 and 3, the FMT will be administered through rectal instillation. Each FMT will be derived from one donor. Donors will be pre-selected based on a species richness and abundance of taxa of interest. The primary outcome will be steroid-free clinical and endoscopic remission at week 8 (Mayo score ≤2, all subscores ≤ 1, and ≥1 point reduction in endoscopy subscore). Fecal, blood and mucosal samples and questionnaires will be collected at different time points. 16S rRNA stool analysis will be performed to assess the microbial changes after FMT.

Mercaptopurine Therapy in Ulcerative Colitis
ColitisUlcerativeThis project is a double-blind, randomized, placebo-controlled, multicenter trial in the Netherlands. The aim of this study is to investigate the therapeutic efficacy of optimized 6-mercaptopurine (6-MP) in ulcerative colitis patients. Therapeutic drug monitoring (TDM) will be performed in order to optimize treatment outcomes and objective endoscopic endpoints will be used.
COlonic Salvage by Therapeutic Appendectomy.
ColitisUlcerativeRationale: The annual incidence of ulcerative colitis (UC) amounts to 6-8 new cases per 100.000. Patients are initially treated medically, and colitis refractory to medical management is treated surgically, mostly by means of an (emergency) colectomy or a proctocolectomy with ileal J-pouch anastomosis. Over the past 10 years evidence has been accumulating indicating that the appendix has an immunomodulatory role in patients with UC reducing the need for medication and perhaps even colectomy. Objective: The objective of this prospective observational cohort study is to evaluate the effect of appendectomy on the disease course of patients with active ulcerative colitis despite standard step-up treatment including biologicals. The second objective is to determine if histological inflammation in the appendix resection specimens can be reliably predicted by pre-operative endoscopic biopsies of the appendix and correlated to clinical and pathological response after appendectomy. Study design: The design of the study is a prospective observational cohort study of 80 consecutive patients. Study population: Sixty patients of 18 years and older, with established diagnosis of UC and ongoing disease activity despite standard step-up treatment including biologicals. Furthermore, histological characteristics in appendix biopsies of 10 patients with non-active UC and 10 'healthy control' patients (e.g. patients undergoing endoscopy for polyps) will be evaluated and used as a reference control group. Intervention: Patients will undergo laparoscopic appendectomy in clinical or day care setting. Main study parameters/objectives: The primary outcome parameter is the number of patients achieving remission (Total Mayo score ≤2) 12 months after appendectomy. Secondary endpoints are reduction of medical therapy, the disease activity as measured with the Mayo score, colectomy rate, the health related quality of life and costs (EQ-5D, EORTC-QLQ-C30-QL and IBDQ), and histological appendix characteristics predictive of response.
Low FODMAP Diet on Nutritional Status, Disease Activity and Gut Microbiota in IBS and UC With Normal...
IBD - Inflammatory Bowel DiseaseIBS - Irritable Bowel Syndrome1 moreGastrointestinal disorders represents 20-50% of referrals to the gastroenterologist; being the most affected womens, youths and older adults. Among these alterations are the Irritable Bowel Syndrome (IBS) and Ulcerative Colitis (UC), which affects the gut causing impaired motility. The pharmacological and nutritional treatment are modified according to the symptomatology and activity of each patients. Currently the implementation of low FODMAP diets for 6 to 8 weeks in patients whith IBS improves symptoms such as bloating, flatulence and abdominal pain. However due to the number of restricted foods a long term attachment could limited the nutritional content, consequently affecting the nutritional status, gut microbiota an quality of life. A low FODMAP diet are useful to improve gastrointestinal symptoms in patients with UC and causes changes in nutritional status.
