Anxiety, depression, chronic inflammation and aortic stiffness in Crohn's disease: the brain--gut--vascular axis.

2020

Background Patients with Crohn's disease have an increased aortic stiffness, a known cardiovascular risk factor. Anxiety, a key factor of the brain--gut axis in patients with Crohn's disease, is implicated in the pathogenesis and progression of the disease, and is linked with aortic stiffening in other clinical settings. Objectives Considering that depression is frequently linked to anxiety in Crohn's disease, we performed a mediation analysis to reveal the potential link between anxiety, depression and aortic stiffness in these patients. Methods Multicentre observational cross-sectional study of 86 consecutive patients with Crohn's disease and 86 matched control individuals. The connection…
