Role of Altered Intestinal Permeability and Lipopolysaccharide in Thrombotic Risk and Vascular Injury in IBD Patients

Sponsor: Fondazione Policlinico Universitario Agostino Gemelli IRCCS

Summary

Chronic inflammatory bowel diseases (IBD), including ulcerative colitis (UC) and Crohn's disease (CD), are characterized by chronic immune-mediated inflammation primarily affecting the gastrointestinal tract. Venous and arterial thromboembolic events are significant extra-intestinal manifestations of IBD, but their pathogenic mechanisms are not fully understood. IBD patients have double the risk of venous thromboembolism (VTE) compared to the general population, with particularly high risk in pediatric patients, and an increased mortality rate. They also face a higher risk of early atherosclerosis and future cardiovascular events, such as myocardial infarction, ischemic stroke, and peripheral artery disease. The prevalence of thromboembolic events in IBD ranges from 1.3% to 7.7%, with venous events at around 5% and ischemic heart disease, cerebrovascular disease, and peripheral artery disease at 1-2%.
