Official title: The Effect of Semaglutide on Endothelial Function, Arterial Stiffness and Liver Indices in Patients Witn Type 2 Diabetes Mellitus and NAFLD

Status Recruiting

Clinical Trial Summary

Fifty patients with diabetes mellitus type 2 and non-alcoholic fatty liver disease (NAFLD) will be enrolled in the study.

25 patients will treated with semaglutide and 25 patients with dipeptidyl peptidase 4 (D-PP4) inhibitors.

At baseline, at four and at 12 months will evaluate the endothelial, cardiovascular and liver function.

Clinical Trial Description

The cardiovascular benefits of semaglutide are established; however, its effect on surrogate vascular markers and liver function is not known.The aim of our study is to investigate the effects of semaglutide on vascular,endothelial and liver function in patients with type 2 diabetes and non-alcoholic fatty liver disease.

A.Overall, 50 patients with diabetes mellitus type 2 and NAFLD will be studied at baseline ,at four and twelve months of treatment:

25 patients will be treated with semaglutide 25 patients will be treated with D-PP4 inhibitors. B. In all patients, the investigators will measure the pulse wave velocity (measured in m/s), pulse wave augmentation index [which is calculated by the formula (P2-P1)/PP x 100, where P1 stands for peak systolic pressure, P2 stands for second peak systolic pressure due to wave reflection and PP stands for Pulse Pressure ], central systolic blood pressure (SBPao, measured in mm Hg) and central pulse pressure (PPao, measured ) with Arteriograph, Mobilograph and Complior, and perfused boundary region of sublingual vessels (5-25 μm in size) using a high-resolution camera with Sideview Darkfield Imaging technique (Microscan, Glucockeck). Perfused boundary region consists the cell-free space which is formed from the separation of red blood cells from plasma at the surface of the endothelial glycocalyx. Increased Perfused boundary region is considered to be an accurate indicator of the reduction of endothelial glycocalyx thickness due to plasma penetration into the glycocalyx.Liver steatosis and stiffness will be measured using Fibroscan® Mini+ 430 (Echosens, Paris, Île-de-France). Controlled Attenuation Parameter (CAP) score will be used as an index of liver fat content, with normal values being < 238 dB/m. E score will be used as an index of liver fibrosis, with normal values being 2- 6 kPa.

The examination will be carried out at the Laboratory of Preventive Cardiology of the 2nd Department of Cardiology of the University of Athens at "Attikon" Hospital. ;
