Summary

Diabetes is a chronic disease characterized by chronic hyperglycaemia, causing microvascular and macrovascular complications. The latter lead to various disabilities: blindness, end-stage renal failure, nerve damage, formation of leg ulcers, and atherosclerosis. In people with type 2 diabetes, the probability of these atherosclerosis associated complications is twice as high as in people without diabetes. Cardiovascular diseases are also the main cause of mortality in people with diabetes.

Preventive measures are therefore crucial. In people with type 2 diabetes, in addition to good glycaemic control, the choice of antidiabetic drugs is also important. Large-scale research has shown that certain glucagon-like peptide (GLP-1) receptor agonists, in addition to improving the regulation of diabetes, also have a significant effect on reducing the macrovascular complications. It is now possible to use semaglutide, a GLP-1 receptor agonist, in the tablet form. Semaglutide lowers blood sugar only when the blood sugar value rises, due to food in the digestive tract, Thus, not increasing the risk of hypoglycaemia. In addition, semaglutide has a significant effect on weight loss and very beneficial, protective effects on the cardiovascular system. Large studies have shown that in its injectable form, it significantly reduces the incidence of cardiovascular death in patients with type 2 diabetes.

Therefore, the aim of the present study is to examine how semaglutide provides protective effects on the cardiovascular system and reduces the risk of diabetes type 2 associated complications.

The present study will include 100 people with type 2 diabetes and last for 12 months. The subjects will receive a semaglutide oral tablet daily in addition to their current treatment (combination of metformin and a sulphonyl urea). At the beginning of the study, after 6 months and at the end of the study (after 12 months of treatment), a detailed clinical examination will be performed and blood will be taken for laboratory parameters. In addition to basic blood tests, inflammatory and oxidative stress parameters, as well as lipid fractions parameters will also be assessed. Ultrasound examination of the changes in the carotid arteries and measures of additional properties of the arteries will also be performed. The confidentiality of the data of the participants in the research will be ensured, as the data obtained during the investigation will be encrypted before processing.
