The aim: of the study was to investigate clinical and genetic determinants of arterial stiffness in children and adolescents with type 1 diabetes mellitus.
Material and Methods: 122 patients (mean age: 16.0 +/- 2.35 years), with an average diabetes duration of 5.0 years and without evidence of arterial hypertension were recruited. Ambulatory arterial stiffness index (AASI) was assessed with 24-h automatic blood pressure monitoring. Body weight, height, HbA1c and plasma lipids were measured. Angiotensin I converting enzyme (ACE) gene insertion (I)/deletion (D) polymorphism was analysed.
Results: Mean AASI equalled 0.22 +/- 0.20 and showed significant, positive correlation with age and BMI-SDS. No association was found between AASI and gender, diabetes duration, daily insulin dose, HbA1c and blood lipids concentration. AASI was higher in non-dippers compared to dippers (0.26 +/- 0.18 vs. 0.19 +/- 0.18, respectively; p = 0.04). In a multivariate model AASI was significantly associated with II homozygosity of ACE gene (p = 0.007).
Conclusions: In type 1 diabetic children and adolescents AASI is correlated with age and BMISDS. Non-dipping status and I-allele were associated with higher arterial stiffness.
