Multicenter prospective cross-sectional study of CD patients, its aim is the construction of an objective and reproducible system for evaluation of Transmural healing in Crohn's Disease (CD). Primary objective : Objective definition of depth or grade of transmural healing in relation to radiologic signs observed during Magnetic Resonance Enterography (MRE) in CD
Mesenteric fat can be invaded by gut bacteria through a process called bacterial translocation, which is the invasion of viable bacteria from the gastrointestinal tract to extraintestinal sites (mesenteric lymph nodes, liver, spleen, kidney, bloodstream, etc.). In Crohn's disease (CD), bacterial translocation could increase the disproportionate inflammatory response already present and contribute to disease progression by stimulating the production of pro-inflammatory cytokines and immune-cell infiltration in the mesentery. Several mechanisms may promote bacterial translocation, such as bacterial overgrowth, disruption of the intestinal mucosal barrier and alterations in the immune system. Ileocecal surgical resection is required in some patients with complicated or refractory CD. Unfortunately, post-surgical disease recurrence happens in up to 40% of cases, probably defining a subgroup of CD patients with a particular aggressive form of the disease. The complete microbiome (in gastrointestinal and extraintestinal sites) in CD patients that develop early post-surgical recurrence, as well as the association to innate immunity alterations, has not yet been studied. The primary aim of the study is to explore the bacterial microbiome of CD patients and its association with early post-surgical recurrence and clinical or genetic variables related to innate immunity. To achieve this, the bacterial DNA present in mesenteric fat and ileal tissue (inflamed and non-inflamed) from surgical resection samples as well as blood samples from CD patients will be studied. Genetic polymorphisms, relevant clinical data and disease recurrence will also be evaluated. The investigators hypothesize that bacterial translocation to the mesentery fat near the inflamed intestine is one of the mechanisms for perpetuation and chronicity of inflammation and therefore post-surgical recurrence in CD. The investigators expect to find a distinctive bacterial profile (in quantity and quality) in the mesenteric fat of patients with early post-surgical recurrence and/or with genetic variants that cause alterations in innate immunity. The study of the microbiome in CD could help to identify the patients with a more aggressive disease form that will probably present early post-surgical recurrence, and could raise the possibility of microbial modulation as therapy for CD.
Crohn's disease (CD) and ulcerative colitis (UC) are chronic inflammatory bowel diseases (IBD) with a heterogeneous disease course. Recurrent mucosal inflammation or chronic subclinical inflammation results in damage to the bowel and complications like stenosis, fistula and colorectal cancer. Therefore, tight control of mucosal inflammation is important to prevent complications. The goal of this multicenter observational cohort study is to determine the best remote monitoring tool for predicting mucosal inflammation in adult patients with inflammatory bowel disease, relative to the gold standard endoscopy. Participants will be asked to fill out questionnaires regarding disease activity (MIAH, mHI, IBD-control, Manitoba IBD Index, p-HBI/p-SCCAI), perform a FC home test and collect one stool sample for routine laboratory calprotectin measurement, before the start of the bowel preparation for the ileocolonoscopy. During this ileocolonoscopy, endoscopic disease activity will be determined. .
ustekinumab (UST) can effectively induce and maintain clinical remission and mucosal healing of Crohn's disease (CD), but some patients still have poor response. Dose optimization is an effective way to improve the response rate of UST, and re-intravenous induction is a common way of optimization. For patients with secondary loss of response, about half of the patients can re-respond after dose optimization. We plan to use CDST-UST to stratify the response level of patients before treatment, select patients with poor response, and initially give multiple intravenous therapy as an intensive induction therapy strategy, so as to improve the response rate of these patients and achieve individualized treatment.
The goal of this study is to learn about a low sulfur diet in patients with Crohn's disease. Study participants will be randomized to receive a low sulfur diet or usual diet for 8 weeks. Participants will work with study nutritionists and receive dietary educational materials. Participants will attend 2 in-person visits as well as 6 phone visits during the study. In addition, subjects will undergo testing, including a test to measure rectal sensation, a test to look for small intestinal bacterial overgrowth, and a test to measure leaky gut.
Many patients with Crohn's disease develop fibrotic narrowing (strictures) in their bowel, causing obstructive symptoms such as abdominal pain, cramping, or vomiting after meals. Because of these symptoms, patients often require bowel resection surgery. The objective of this clinical trial is to evaluate the safety, pharmacokinetics, and pharmacodynamics of AGMB-129 in patients with Crohn's disease and symptomatic strictures, and whether it can have a beneficial effect on intestinal strictures. The participants will be in the study for a total duration of up to 19 weeks, including a 5-week screening period, a 12-week double-blind, placebo-controlled treatment period where they will receive either a high or low dose or placebo (1:1:1), and 2-week safety follow-up period
Crohn's disease (CD) is an incurable chronic inflammatory disorder of the gastrointestinal tract. This study will assess how safe and effective risankizumab is in treating moderately to severely active CD in real world. Adverse events and change in disease activity will be assessed. Risankizumab is a drug approved for the treatment of CD. All study participants will receive risankizumab as prescribed by their study doctor in accordance with approved local label. Approximately 1000 participants will be enrolled worldwide. Participants will receive risankizumab as prescribed by their physician according to their routine clinical practice and local label. Participants will be followed for up to 36 months. There is expected to be no additional burden for participants in this trial. Study visits may be conducted on-site or virtually as per standard of care.
This is a study to evaluate vedolizumab for injection (300 mg) as a safe and active treatment for Crohn's Disease in adults in China. Participants will receive an injection of Vedolizumab 300 mg at scheduled weeks 0, 2, and 6, and starting at week 14, every 8 weeks over 58 weeks or starting at week 18, every 4 weeks over 54 weeks. There will be up to 20 study visits over 58 weeks to complete assessments.
To evaluate the safety and feasibility of ExoFlo as a treatment for Perianal Fistulizing Crohn's Disease.
