BACKGROUND: Ulcerative colitis (UC) is characterized by chronic relapsing-remitting inflammation of the gastrointestinal tract. The chronic inflammatory process may predispose to atherosclerosis. The aim of the study was to assess the carotid intima-media thickness (CIMT) and its relation to subclinical atherosclerosis and to follow up cardiovascular complications in patients with UC. METHODS: 83 patients with proven UC in remission were enrolled in the study. 42 age- and sex-matched healthy controls were taken. Patients with known risk factors for atherosclerosis were excluded from the study. Baseline blood investigations along with C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), and fasting lipid profile were done. CIMT was measured using B-mode Doppler imaging study. RESULTS: The mean age of the UC patients was 37.06 ± 14.87 years. Left-sided colitis (45.8%) was the commonest type of presentation according to the extent of the disease. Mean CIMT (0.55 ± 0.17) was significantly higher in UC patients when compared to mean CIMT (0.46 ± 0.13) in the control group (p = 0.002). In Pearson correlation analysis, age, ESR, and CRP were positive and significantly correlated with CIMT. Multiple linear regression analysis (R<sup>2</sup> = 0.18, p = 0.0026) revealed that age and CRP were significant independent predictors of mean CIMT. On following up for 6 months, 4 patients with UC had complications in the form of venous thrombosis. CONCLUSION: CIMT is a simple, noninvasive, reliable and objective auxiliary vascular parameter of structural alteration in UC patients.
