The risk of type 2 diabetes appears to be higher in patients with chronic inflammatory diseases, including chronic inflammatory bowel disease (IBD). IBD is a group of inflammatory diseases that includes mainly Crohn's disease and ulcerative colitis. Although the majority of IBD patients are not overweight, the prevalence of obesity in this population remains significant, estimated at 15 to 40%. It has been shown that obesity can impact the response to therapies used in IBD as well as the clinical course of the disease: 1) plasma concentrations of immunomodulatory therapies are often lower in the obese compared to those with a normal Body Mass Index (BMI) with a lower dose per kg of the administered drug as well as an acceleration of drug clearance. 2nd) Surgical management of IBD is associated with a higher risk of peri- and post-operative complications in obese patients, including an increase in operating time, bleeding risk, length of hospital stay and percentage of post-operative infections. 3e) Finally, obesity seems to have a negative impact on the clinical course of IBD, with a correlation between an increase in BMI and an increase in the number of hospitalizations, the number of follow-up consultations and the need for therapeutic escalation. One of the common pathophysiological explanations between IBD and metabolic syndrome (including type 2 diabetes and obesity), would involve metabolites in the gut that are modulated by the gut microbiota. Glucagon-Like Peptide 1 (aGLP1) analogues are a new class of injectable antidiabetic drugs that have revolutionized the management of type 2 diabetes. They include exenatide, lixisenatide, liraglutide, dulaglutide and semaglutide. They combine an effect on glycemic control but also usually a weight loss. In some countries, they are used in non-diabetic obese patients, with a weight loss of up to -10 to -15%. These molecules bind to GLP1 receptors, stimulate insulin secretion when blood glucose levels are high, decrease glucagon secretion, slow gastric emptying and stimulate satiety. In addition to glycemic control, weight reduction is most often associated. In addition, some aGLP1s have been shown to reduce cardiovascular events in diabetics. They are well tolerated, but their side effects are mainly digestive, such as nausea, vomiting and sometimes diarrhea. These problems occur in about 20% of cases, most often after the first injection, with vomiting requiring permanent cessation of treatment. Most often they gradually subside, spontaneously or after symptomatic treatment, and allow titration of the drug. Due to the lack of studies and possible intestinal effects, aGLP1 is not recommended in cases of severe gastrointestinal disease, and therefore in cases of IBD, although it is not contraindicated. The main objective of this study is to test the interest of these GLP1 analogues in type 2 diabetics with IBD, who are overweight and whose glycemic target is not reached. The expected benefit is to facilitate diabetes control and weight loss in this population. The second objective is to monitor the occurrence of adverse events in this population with the different GLP1 analogues used.
The overall purpose of this study is to describe the cellular composition of the human colon and its gene expression using scRNAseq and scATACseq methods. This will potentially provide is with a detailed map of the colon aiding our understanding of how diseases of the colon develop as well as the colons influence on systemic diseases such as type II diabetes.
This is a pilot, prospective, double-blinded, two-arm, randomized controlled trial of the efficacy of Frondanol in comparison to placebo in decreasing bowel inflammation in patients with a clinical diagnosis of inflammatory bowel disease who are in remission and on standard of care treatment.
Active inflammatory bowel disease (IBD) causes disabling symptoms such as diarrhea, involuntary loss of bowel control, abdominal pain and urges to pass stool. However, even patients with inactive IBD frequently experience such symptoms. The cause is not well understood and the functionality of the bowel in IBD patients is underexplored. Earlier studies show a wide range of results, but most find that patients with IBD in remission are up to four times as likely to report gastrointestinal symptoms when compared to healthy controls. Chronic inflammation may cause changes of the bowel wall, like increased collagen deposits (fibrosis) and thus cause symptoms, but the absence of active inflammation in combination with presence of symptoms may also be regarded as resembling the clinical condition of irritable bowel syndrome (IBS). IBS is characterized by abdominal pain and changes in stool frequency and consistence and is often associated with disorders like depression and anxiety. Up to a third of IBD patients without signs of disease activity meet the criteria for IBS (irritable bowel syndrome. It can be speculated that an IBD diagnosis is a distressing event that can induce mood disorders, and an IBS-like condition. Characterization of IBS patients relies on the Rome IV symptom criteria, symptom severity scales and measurements of rectal sensibility and rectal compliance using a barostat procedure. Motor function assessment relies on anorectal manometry which detects abnormalities of muscle function and coordination. Recently, a standardized high-resolution anorectal manometry protocol (HRAM) was published which also evaluates sensitivity and compliance. The level of agreement between the barostat method and the HRAM testing procedure regarding sensibility and rectal compliance is largely unknown. Recent studies have associated gut microorganisms, genetic factors, and proteins with various aspects of IBD. There is evidence that these potential markers may reflect non-inflammatory processes such as fibrosis. The aim of this study is to explore the anorectal function in symptomatic patients with inactive IBD compared to healthy volunteers and asymptomatic patients, evaluate symptom severity and psychological parameters and perform molecular characterization. The level of agreement of rectal sensitivity and compliance measurements with the barostat method and HRAM protocol will also be evaluated.
Pathologically Inflammatory bowel disease (IBD) is in chronic complex inflammatory gut pathological condition. Although the etiology of IBD is unknown, gut microbiota alteration (dysbiosis) is considered a novel factor involved in the pathogenesis of IBD. The aim of this study is to analyze gut microbiota in IBD patients.
This study will investigate the perception of the relationship between smoking and inflammatory bowel disease by surveying inflammatory bowel disease patients. Afterward, the relationship between smoking and inflammatory bowel disease will be explained, and the smoking cessation rate will be investigated three months later.
Purpose: To demonstrate that personalised therapy can be delivered to patients with IBD, by treating patients with an increased risk of poor disease course, defined by a serum protein signature at diagnosis, with a top-down treatment, and that this treatment strategy improves clinical outcomes. Objectives: Primary objective: To assess if a top-down treatment can improve treatment outcomes in IBD patients with a high risk of poor disease course, defined by a serum protein signature at diagnosis. Secondary objective: To assess if a top-down treatment can improve quality of life and health resource allocation in IBD patients with a high risk of poor disease course, defined by a serum protein signature at diagnosis. Study design: A multi-centre, biomarker-stratified open-label controlled trial, where newly diagnosed IBD patients are randomised (1:1) to a group with access to the protein signature or a group without access to the protein signature. Study subjects within the protein signature arm who display a high-risk protein profile, will be treated according to a top-down treatment algorithm (anti-TNF agent with/without an immunomodulatory) and subjects without access to the protein signature will be treated according to current clinical practice. Study population: Newly diagnosed IBD patients. Number of subjects:250 Primary variables: Composite of both corticosteroid-free clinical remission and endoscopic remission at Week 52, defined as below. Surgery because of IBD during follow-up will be defined as treatment failure. Ulcerative colitis; - Clinical remission per patient reported Mayo: A stool frequency subscore (SFS) ≤ 1, and not greater than baseline, and a rectal bleeding subscore (RBS) of 0. - Endoscopic remission: An endoscopic Mayo subscore of 0 (OR in patients without endoscopy at week 52, normalization of f-Calprotectin, defined as < 250μg/g Crohn's disease; - Clinical remission: An average daily Stool Frequency (SF) ≤ 2.8 and not worse than Baseline AND average daily Abdominal Pain (AP) score ≤ 1 and not worse than Baseline. - Endoscopic remission: SES-CD≤2 (OR in patients without endoscopy at week 52, normalization of f-Calprotectin, defined as < 250μg/g.
Two types of inflammatory and autoimmune diseases (excluding monogenic diseases) can be distinguished in children: those similar to adult diseases but with an early onset (type 1 diabetes, inflammatory diseases of the gastrointestinal tract, rheumatoid arthritis with anti-CCP antibodies) and those specific to children that are not described in adults (early-onset juvenile idiopathic arthritis with anti-nuclear and anterior uveitis). The familial and nosological aggregations suggest that these diseases are probably polygenically determined, and result from interactions with the environment. In a singular way, the incidence of "adult" diseases is increasing while the age of onset is getting earlier; conversely, there is no increase in early-onset juvenile idiopathic arthritis. On the other hand, the influence of early events that may alter the microbiotic environment is different for different diseases: whereas cesarean section (or early antibiotic therapy) has been shown to increase the risk of JIA and T1DM, it does not seem to change the risk of IBD. We hypothesize that environmental factors, particularly those related to diet and bacterial and fungal digestive microbiota - are different between these disease categories.
