Background/Aims: Mesenteric microvascular thrombosis has been implicated as a contributing factor to the pathogenesis of inflammatory bowel disease (IBD). The aim of the current study was to assess the possibility of subclinical atherosclerosis in patients with IBD by measuring their carotid intima-media thickness (c-IMT). Methods: Thirty-eight patients with IBD who were followed-up for at least 3 years participated. Patients with a history of cardiovascular disease and known risk factors for atherosclerosis were excluded. As a control group, 38 healthy patients matched for age and gender without atherosclerosis risk factors were included. Carotid ultrasonography was performed in all patients and controls. Patient baseline characteristics and laboratory parameters were recorded to evaluate atherosclerosis risk factors. Results: The mean age of patients with IBD was 38.5±6.62 years. Twenty-three patients with IBD were diagnosed with ulcerative colitis and the other 15 cases were diagnosed with Crohn’s disease. The median duration of disease was 52.0 months. Serologic markers such as erythrocyte sedimentation rate, C-reactive protein (CRP), and cholesterol levels differed significantly, however, there was no significant difference in c-IMT between patients with IBD and those in the control group (0.53±0.10 mm vs. 0.53±0.07; P=0.85). Multivariate analysis revealed that body mass index, CRP, disease duration, and age were significantly correlated with c-IMT in patients with IBD. Conclusions: The results of the current study did not show an increase in c-IMT in patients with IBD. Further studies that include more subjects and a longer follow-up period will be necessary in order to evaluate the risk of atherosclerosis in Korean patients with IBD.
