Interest of GLP1 Analogues in Overweight Type 2 Diabetic Patients With Chronic Inflammatory Bowel Disease

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, de
