Evaluation of endothelial function in patients with Behçet’s disease in remission: A cross-sectional study

Objective: Endothelial dysfunction is an initial stage of the atherogenic process, which can be evaluated by a noninvasive method (flow-mediated dilation - FMD) and has a well-established prognostic value for cardiovascular (CV) risk. Currently, there is no evidence of increased CV mortality in Behc¸et’s disease (BD), although its association with endothelial dysfunction has been described. There are still doubts in the literature whether the presence of chronic vascular inflammation might trigger the development of atherosclerosis, despite BD remission, which is why this study was conducted.

Methods: We analyzed 24 subjects in this cross-sectional study (12 patients with BD in remission and 12 subjects matched by gender age). Endothelial function was analyzed via FMD.

Results: The lowest median for FMD was presented by the BD group (2.025% - interquartile range (IQR) 7.785 versus 5.46% - IQR 3.625, P ¼ .18). The median total cholesterol in the BD group was lower than the controls (168 mg dL–1 - IQR 46 and 216.5 mg dL–1 - IQR 54, respectively, P ¼ .0193). In the right carotid artery, the intima-media thickness was equal to 0.740 - IQR 0.16 for the patients and 0.740 - IQR 0.11 for the controls (P ¼ .9473); on the left, 0.725 - IQR 0.13 and 0.745 - IQR 0.120 (P ¼ .4333), respectively.

Conclusion: The lower median trend of FMD in patients with BD suggests endothelial dysfunction, despite clinical remission of the inflammatory disease, although our study is limited by the sample size and greater use of statins in BD group.
