Abstract
Objective:
We evaluated structural and functional characteristics of the common carotid artery (CCA), a marker of early carotid
atherosclerosis, and investigated their relation to metabolic and anthropometric parameters in children and adolescents with type 1
diabetes.
Materials and methods:
Non-invasive ultrasonographic measurements were made in 45 type 1 diabetic patients and 33 controls.
Age, sex, and body mass index were matched between patients and controls. We investigated intima-media thickness (IMT),
compliance, distensibility, diastolic wall stress (DWS) and incremental elastic modulus (IEM) of the CCA. Metabolic and
anthropometric parameters such as serum lipids, plasma glycated haemoglobin, body mass index, waist–hip ratio and blood
pressure were assessed.
Results:
The diabetic patients had significantly higher CCA-IMT than the controls (0.48 0.06 mm versus 0.33 0.07 mm;
p
< 0.001). The diabetic children had significantly higher values than the controls for DWS (1.18 0.29 mmHg 102 versus
0.81
0.25 mmHg 102; p < 0.001) and for IEM (1.26 0.57 mmHg 103 versus 0.77 0.28 mmHg 103; p < 0.001). The
difference was not significant between patients and controls for arterial compliance and for distensibility (
p > 0.05). In a
multivariate regression model for all subjects, diabetic state was the best predictor of IMT (
p < 0.001), DWS ( p < 0.001) and IEM
(
p = 0.001).
Conclusion:
Our results suggested that children and adolescent patients with type 1 diabetes are associated with early impairment
of CCA structure and function and that diabetic state may be the main risk factor for CCAwall stiffening and thickening, which are
of considerable concern as possible early events in the genesis of atheroma.
