People with inflammatory bowel disease (IBD), such as ulcerative colitis or Crohn's disease affecting the colon, have a higher risk of developing colon cancer over time. To catch early signs of cancer, regular colonoscopies are recommended. In this study, the investigators are comparing two advanced methods of examining the colon during these surveillance colonoscopies. One method uses a special dye sprayed inside the colon to highlight abnormal areas (called dye-based chromoendoscopy). The other method uses new technology built into the camera to enhance the view without needing any dye (called virtual chromoendoscopy). Both methods use modern, high-definition equipment. The purpose of this study is to find out if the newer, dye-free method is as good as the traditional dye method at detecting pre-cancerous changes (called dysplasia) in people with IBD. Adults with IBD who are due for a routine surveillance colonoscopy may be invited to take part. Participants will be randomly assigned to one of the two methods. No additional procedures are involved, and only the way the colon is viewed differs. The investigators will also look at how long the procedures take, how many biopsies are needed, any complications, and how patients experience the exam. Participants will be followed over time using national health records to check for long-term outcomes. This research will help doctors better understand which method is most effective and comfortable for patients, and may guide future recommendations for cancer screening in people with IBD.
NCT07298421

NCT07338565
Individuals with gastrointestinal diseases - such as Crohn's disease, ulcerative colitis, ileostomy, or bile acid diarrhoea - are at increased risk of magnesium deficiency. Magnesium is a vital mineral that supports many essential functions in the body, including muscle contraction, nerve signalling, heart rhythm, and bone health. Deficiency may contribute to fatigue, muscle cramps, abnormal heart rhythms, and reduce the quality of life. The purpose of this study is to investigate the prevalence of magnesium deficiency in individuals with these conditions and to identify the most accurate and practical methods for assessing magnesium status in clinical care. Although plasma magnesium is commonly used in routine blood tests, it represents only about 1% of the body's total magnesium and may not reflect true magnesium levels within cells or tissues. Hence, this study compares several different ways of measuring magnesium, including: * Plasma magnesium * Magnesium levels in red and white blood cells (PBMC, RBC, and buffy coat) * Magnesium levels in muscle tissue (via biopsy) * A magnesium retention test, based on how much magnesium is excreted after an infusion The study includes four groups: 1. Patients with inflammatory bowel disease. 2. Patients with an ileostomy. 3. Patients with bile acid diarrhoea. 4. Healthy individuals (control group). All participants will provide blood and urine samples, and some may undergo optional biopsies of muscle or intestinal tissue. Participants will also complete questionnaires and undergo tests of muscle strength and body composition. The findings are expected to enhance the understanding and detection of magnesium deficiency in patients with gastrointestinal diseases and to aid in the development of more effective tools for identifying and treating this common yet often overlooked condition.
NCT06001450
The PLANET Study aims to determine the impact of microplastics on intestinal inflammation and gut microbiome in order to understand the role of this pollutant on the risk of developing inflammatory bowel disease (IBD) as well as other diseases. With this information, the researchers hope to characterize better the role of environmental pollutants on IBD and develop novel strategies towards prevention.

NCT05452304
This study will assess the safety, tolerability, immunogenicity, and pharmacokinetics (PK), and explore the pharmacodynamics (PD) following single ascending dose administration and repeat dose administration in healthy subjects and patients with Crohn's disease.
NCT07169123
The study looks at how eating salt affects gut health in people with Crohn's disease. The aim of the study is to find out whether eating more salt increases the breakdown of proteins in the gut and if this makes inflammation and symptoms worse. By studying the link between salt, gut bacteria and inflammation, the study hopes to improve diet advice for people with Crohn's disease. This research may help find specific foods that affect the disease and lead to better, more personalized nutrition plans.
NCT06890637
Advanced therapies including biologics and small molecules target specific inflammatory pathways. IBD's multifactorial etiology means that blocking a single pathway may not be sufficient for all patients. Even when combination of advanced therapies are used, the incremental benefits often diminish, reflecting the therapeutic ceiling. Furthermore, safety concerns also limit the potential to push beyond this ceiling. Increasing the dose or adding more immunosuppressive agents can lead to a higher risk of infections, malignancies, and other adverse effects, making it impractical to continually intensify treatment. Understanding the therapeutic ceiling in IBD highlights the need for innovative approaches that go beyond current strategies. Given the diverse microbial and immunological landscapes in IBD combining fecal microbiota transplantation (FMT) and Crohn's Disease Exclusion Diet (CDED) with advanced therapies represents a promising approach to break the therapeutic ceiling in CD. This strategy leverages the complementary mechanisms of action of FMT/CDED and advance therapies, potentially offering a more comprehensive treatment modality that addresses the complex and multifactorial nature of IBD. FMT involves the transfer of gut microbiota from a healthy donor to a patient, aiming to restore a balanced microbial community in the intestines. This can help modulate the immune system and reduce inflammation, which are central to Crohn's disease pathology. This study seeks to provide evidence on whether addition of microbiota manipulation by FMT and CDED offers additional benefits when used alongside advance therapies in active CD. The findings from this RCT are expected to significantly enhance treatment strategies, ensuring that patients receive the most effective and appropriate care based on robust scientific evidence. This multi-center double blind placebo-controlled RCT will randomize patients in 1:1:1:1 ratio to FMT, CDED and advance therapy vs sham FMT with advance therapy and CDED vs FMT, Advance therapy and sham diet vs Advance therapy with sham FMT and sham diet for induction and maintenance of remission in patients of active Crohn's disease. Randomization will be held centrally to ensure concealment of allocation. Random numbers will be generated by computerized random number schedule (The RAND), and the randomization list and numbered packing of the intervention will be prepared by a person not involved in the study. Randomization will be performed using permuted blocks of 8. Both the patient and the investigator will be blinded to the intervention
NCT06723418
Children with inflammatory bowel disease (IBD) including both Crohn's disease (CD) and ulcerative colitis (UC) can be at high risk of developing malnutrition due to the nature of their condition. It is also believed that some children with IBD, in need of nutritional care, are not identified quickly by their healthcare professionals. This may negatively affect their nutrition, disease progression and general well-being. Hence, it has been proposed that nutritional screening tools or scores (NSTs) should be used to promptly identify children needing further dietetic review and input. Although there are a few NSTs for generic use in sick children at hospital admission, NSTs or scores to use for children with IBD are currently missing. In this study, we would like to test the performance of an existing tool that is routinely used for all sick children at hospital admission (The Paediatric Yorkhill Malnutrition Score or PYMS)(5) and test whether PYMS can detect children with IBD who are at risk of malnutrition. If PYMS doesn't work well, we will develop a specific tool for children with IBD (The Paediatric IBD Nutrition Score or PIBD-NUTS).
NCT05842564
Crohn's disease is a multifactorial complex disease resulting in a between microbiota and immune system. Indeed, GWAS (Genome-Wide Association Studies) association study pinpointed polymorphisms as genes susceptibility on more than 200 loci. Among them genes coding for proteins involved in autophagy machinery (i.e: ATG16L1, IRGM et NDP52). Autophagy is a ubiquitous intracellular mechanism mandatory for protein and microorganism recycling. So far, the role of autophagy in gut inflammation and intestinal homeostasis in Crohn's disease patients is partially understand. Then, investigators plan to evaluate, on native cells, the autophagic flux in pediatric patients suffering of a Crohn's disease compare to controls.

NCT02503514
Purpose: Inflammatory bowel disease patients undergoing treatment with varying biologic agents will be evaluated for incidences of paradoxical immune reactions, the risk factors associated with those paradoxical immune reactions, and whether the paradoxical immune reactions and their associated risk factors differ based on formulation of biologic agent. Participants: All adults (≥18 year) with confirmed IBD on a biologic agent or with plans to initiate treatment in 1 month Procedures (methods): Subjects undergoing treatment with a biologic agent will be followed indefinitely for paradoxical immune reactions. Data will be collected at baseline as well as serum and plasma for banking. Subjects will be followed at 6 month intervals either via email, telephone interviews or at the time of clinic follow-up visits. In the event of a de-novo paradoxical reaction, specific information will be collected from sites in an event capture form, with data abstracted from routine clinical care for the paradoxical reaction. Subjects will continue to be followed every 3 months after the event via email, telephone contact to determine whether resolution and/or recurrence occurred, and to determine any changes in medical therapy. Serum and plasma will be re-collected at the time of first event for comparison to baseline samples and to samples from controls (those on biologics without study documented paradoxical immune reactions). At resolution of the event, patient will return to 6 month follow up schedule. Subjects can discontinue and/or fail a particular biologic treatment; therefore they will also be followed for paradoxical immune reactions, on any new biologic treatment they undergo while in the study.
