Indeed, thanks to recent therapies with novel mechanisms of action, including those with biologics and small molecules, it has been possible to reduce the mortality rate of IBDs. However, a significant percentage of IBD patients remain refractory to these multiple advanced therapies. Therefore, another challenge of IBD research remains the development of novel therapies with novel agents or cells that could improve the quality of life and outcome of IBD patients. Furthermore, another aspect to be studied in IBDs is not only the high risk of progression not only to neoplastic transformation but also to the development of cardiovascular disease (CVD).
