Abstract

Background Type-1 diabetes mellitus (T1DM) causes endothelial dysfunction and early atherosclerosis, which can result in premature coronary artery disease. The aim of this study was to determine the impact of glycemic control, vascular oxidative stress and inflammation on vascular health in adolescents with T1DM. Methods This was a cross-sectional study in adolescents with age- and sex-matched T1DM who were ≥12 years and were at least 2 years post-diagnosis. Recruitment was balanced to include individuals with hemoglobin A1c (HbA1c) ≤8.5% (n=27) or with HbA1c ≥9.5% (n=25). Biomarkers of inflammation were measured in the blood including C-reactive protein (CRP), interleukin-6 (IL-6), intercellular adhesion molecule-1 (ICAM-1), E-selectin, fibrinogen and tumor necrosis factor-α (TNF-α). Carotid intima media thickness (cIMT) and peripheral arterial tonometry (PAT) were assessed. Results Plasma E-selectin level was significantly different between the two groups with higher levels in the group with HbA1c ≥9.5% (65.0±27.7 ng/mL vs. 48.8±21.5 ng/mL, p=0.02). Though cIMT and PAT were not significantly different between the groups, Pearson correlation showed a significant direct relationship between rising HbA1c and mean right cIMT (p=0.02; r=0.37), PAT (p=0.03, r=0.31) and fibrinogen (p=0.03, r=0.03). Conclusions Elevated E-selectin level is an early marker of oxidative stress in T1DM patients with an elevated HbA1c level. Suboptimal glycemic control as evidenced by a rising HbA1c causes early atherosclerosis.
