Increased carotid intima media thickness indicates subclinical atherosclerosis. We evaluated the relation between vitamin D level and intima media thickness in patients with type 1 DM. 93 patients (female/male: 48/45, aged 31.5 +/- 11.9 years, A1c 9.48 +/- 2.43, vitamin D [15.9 (12.1-19.2)]) with type 1 DM were included into the study. Common carotid artery IMT was measured by real time B mode ultrasonography (MyLab 70 XVG, Esaote SpA, Genoa, Italy). Vitamin D was measured using radioimmunassay. Male and female patients (n = 14, 15%) had similar rates of plaque presence (p = 0.377). IMT was similar according to gender. IMT [0.45 (0.40-0.50)] was positively correlated with age, duration of diabetes, creatinine, LDL/HDL ratio, and ALP. Median IMT was higher in current smokers, patients with retinopathy, and nephropathy, and overweight/obese patients. IMT was not different according to vitamin D status. However calcium level corrected for albumin was in positive correlation with mean IMT (r = 0.221, p = 0.033). We detected high frequency of vitamin D deficiency (78%) defined as less than 20 ng/ml. Vitamin D and diabetes control defined as A1c have no effect on intima media thickness in type 1 DM. Traditional cardiovascular risk factors including age, duration of DM, smoking, and BMI adversely affect intima media thickness.
