An elevated serum level of endothelial monocyte activating polypeptide-II in patients with arterial hypertension with and without type 2 diabetes and obesity

Objectives: To assess serum levels of endothelial monocyte activating polypeptide-II (EMAP-II) in patients with arterial hypertension with and without type 2 diabetes mellitus and obesity.Materials and methods: We examined 41 hypertensive patients with type 2 diabetes, 18 obese hypertensive patients without diabetes, 9 non-obese hypertensive patients without diabetes, and 18 healthy control subjects.Results: We found an increased serum level of EMAP-II in hypertensive patients with type 2 diabetes compared to controls (4.86±2.3 and 1.08±0.53 ng/ml respectively, р0.01), in hypertensive patients with obesity (2.92±1.42 ng/ml) compared to controls, and in non-obese hypertensive patients (2.02±0.33 ng/ml) compared to controls. Also, the levels of EMAP-II significantly correlated with HbA1c, blood glucose, serum insulin levels, HOMA, lipids, and body mass index (р0.01).Conclusions: The revealed changes could reflect an endothelial dysfunction mostly pronounced in patients with arterial hypertension, type 2 diabetes mellitus and obesity. Hyperglycemia, dyslipidemia, insulin resistance, obesity appear to be significant contributing factors leading to the elevation of EMAP-II.
