The risk of cardiovascular comorbidity in children with Behçet's disease

Objective: Patients with Behcet's disease (BD) may experience long-term morbidity caused by various forms of cardiovascular disease. This study aimed to assess the risk for cardiovascular comorbidity in paediatric BD patients with and without vascular involvement, independent of the contribution of traditional risk factors. Methods: Paediatric patients classified as having BD according to the 2015 Peadiatric BD (PEDBD) criteria were included in the study. Twenty-four-hour ambulatory blood pressure monitoring (ABPM), transthoracic echocardiography, and carotid intima-media thickness (cIMT) measurements were performed. Patients with an active disease or those who have other known risk factors for cardiovascular disease were not included in the study. Results: Thirty-one children and adolescents with paediatric BD (16 female, 51.6%; F/M: 1.06) were enrolled in the study. Among the BD patients, 10 patients (34.4%) had abnormal ABPM. Carotid IMT values, mean arterial pressure, systolic and diastolic blood pressure by ABPM and the prevalence of abnormal ABPM, non-dipping, and ambulatory hypertension were similar between patients with and without vascular involvement. The echocardiography measurements showed that BD patients with vascular involvement had a significantly higher velocity and velocity time integral of the left ventricle outflow tract, which may indicate increased stiffness of the aorta. Conclusion: Paediatric BD patients with vascular involvement may tend to have more cardiovascular risk factors. However, cardiovascular assessment should be considered in all BD patients, regardless of the involved systems. We suggest that ABPM may accurately define hypertension and cardiovascular risk in BD.
