Abstract: Studies indicate that risk for type 2 diabetes mellitus (T2D) or cardiovascular disease is detectable in childhood, though these disorders may not emerge until adulthood. This study was aimed to assess the markers of endothelial dysfunction in patients with the family history of T2D from South Indian population. A total of 450 subjects were included in the study comprising Group I (n = 200) of T2D, Group II (n = 200) of age- and sex-matched healthy controls, Group III (n = 25) of children of T2D patients and Group IV (n = 25) of children of healthy controls. Results showed that intimal medial thickening (IMT) was significantly higher in T2D patients, compared with control subjects with no family history of diabetes. The fasting plasma glucose, glycated hemoglobin, serum total cholesterol, triglyceride, LDL-cholesterol, apolipoprotein B (ApoB) and high-sensitive C-reactive protein (hsCRP) levels were significantly increased, whereas HDL-cholesterol and serum nitrite levels were significantly decreased in T2D patients. However, children of T2D patients who were not diabetic did not show significant increase in the IMT, as compared to those of healthy controls. In conclusion, the present study demonstrated that IMT was significantly higher in the T2D patients and increased with age and family history. The increased levels of lipids, hsCRP, IMT and decreased nitrite levels might contribute to the risk of endothelial dysfunction in patients with T2D. However, further studies are warranted with other biomarkers of endothelial dysfunction in T2D patients with increased sample size.
