Background: Atherosclerosis is one of the most important causes of death worldwide. Detection and prevention of the organ damage and determination of the risk due to atherosclerosis is getting more and more important in recent days. Brachial Intima-Media Thickness (B-IMT), mean platelet volume (MPV), paraoxonase (PON) and arylesterase (ARE) are accepted as markers of atherosclerosis. In this study we aimed to determine the importance of B-IMT, ARE, PON and MPV levels in four patient groups which are expected to have increased risk of atherosclerosis without vascular complications. Methods: A total of 100 patients (32 prediabetic patients = group 1, 13 subclinical hypothyroidism + prediabetic = group 2, 20 subclinical hypothyroidism = group 3, 35 diabetic patients = group 4) are enrolled into the study. Height, weight, BMI, age, gender, smoking, alcohol, exercise, family history of diabetes mellitus and cerebrovasculer disease, childbirth, menopause status and HOMA levels of all patients were recorded. Routine biochemical tests and Alc, lipid profiles, homocysteine, PON, ARE were performed and brachial artery index was measured. Results: There were no significant differences in age, B-IMT, BMI, homocysteine, MPV, PON and LDL, HDL levels between the groups. We found a significant difference in A1c (p=0.001), glucose (p=0.0001), ARE (p=0.0001), triglyceride (p=0.005) and HOMA-R (p=0.0001) levels between groups. The significant correlations were shown in Table-1. Conclusions: The relationship between insulin resistance, lipid profile, TSH, B-IMT, PON, ARE and MPV are not similar in different patient groups. This is probably due to varying degrees of atherosclerosis in patients.
