β¦ Synopsis
To investigate associations between early atherosclerosis and possible risk factors for it in young patients with established Type 1 diabetes mellitus (DM), we measured the combined intima-media thickness (IMT) of the common carotid arteries with high resolution ultrasound in 310 young patients (age Υ 40 years, mean 27.9 Β± 6.5) with a diabetes duration Υ 2 years, and in two control groups of similar age (control 1:40 healthy subjects, control 2: 40 Type 1 DM recently diagnosed patients). Albumin excretion rate and lipids (total cholesterol and triglycerides) were measured and retinopathy and hypertension (systolic blood pressure ΟΎ 140 or diastolic blood pressure ΟΎ 90 mmHg) sought in the patients. Mean maximum IMT was 0.52 Β± 0.06 mm in control group 1 and 0.50 Β± 0.05 mm in control group 2 with a mean difference of 0.02 mm (95% CI: -0.01, 0.04). The more established Type 1 DM patients had a significantly greater IMT (0.57 Β± 0.13 mm, p Ο½ 0.001) than both control groups. In a subgroup analysis, patients with microvascular diabetic complications (n = 99) had a significantly greater IMT (0.63 Β± 0.17 vs 0.55 Β± 0.10 mm, p Ο½ 0.001) than those without (n = 211). In a multiple linear regression analysis with a significance level of Υ 0.10, the carotid artery IMT of our established diabetic patients was related to age, male gender, triglycerides and nephropathy, suggesting the latter as the main diabetes-specific risk for intima-media thickening in young Type 1 DM patients.
