    Abstract:
    BACKGROUND & AIMS: Recent studies documented an increased cardiovascular risk in patients with inflammatory bowel disease (IBD). Our study aimed at investigating the prevalence of intima-media thickness (IMT) of the carotid arteries and the arterial stiffness indices as markers of early atherosclerosis in young IBD patients. METHODS: We recruited 68 consecutive IBD patients, and 38 matched healthy controls less than 45years old (median age 31.6±8.1years). Clinical and demographic features, cardiovascular risk factors, history of cardiovascular events, concomitant therapies were registered on a dedicate database. Carotid IMT was evaluated by using high resolution B-mode ultrasonography. Arterial stiffness was assessed by measurement of carotid-femoral Pulse Wave Velocity (PWV) and Augmentation Index (AIx). RESULTS: Total cholesterol (P<0.013) and LDL-cholesterol (P<0.019) levels were significantly lower in IBD patients compared to controls. Carotid IMT was higher in IBD than in controls (P<0.047), but there was no statistically significant difference among Crohn's Disease (CD) and Ulcerative Colitis (UC) patients. Moreover, PWV and AIx were significantly higher in patients as compared to controls (P<0.006 and P<0.004 respectively). No medication seemed to affect vascular measurements, though stiffness parameters were significantly higher in patients treated with 5-ASA (11.9 (9.7) vs 18.2 (10.2), P<0.021), suggesting a lack of efficacy of 5-ASA in protecting IBD patients from early atherogenesis. CONCLUSIONS: Young IBD patients show an increase in subclinical markers of atherosclerosis. Future studies need to address whether these markers result in an increased risk of cardiovascular events in these patient.
