Brief Title ICMJE | Effect of Angiotensin Receptor Blockade on Insulin Resistance and Adipose Tissue Cytokines in Type 2 Diabetes | ||||
Official Title ICMJE | Effect of Acute Angiotensin Receptor Blockade on Insulin Resistance and Selected Cytokines in Adipose Tissue in Type 2 Diabetes | ||||
Brief Summary | The study aims to investigate the effect of acute angiotensin receptor blockade on insulin action/insulin resistance and expressions of selected adipocytokines in subcutaneous adipose tissue in insulin-resistant subjects with type 2 diabetes and healthy controls. Hypothesis: Changes in adipocytokine concentrations and/or expressions and different reactions to acute in vivo induced hyperinsulinemia and angiotensin receptor blockade will be found in patients with type 2 diabetes compared to healthy subjects. A significant relationships between insulin sensitivity and selected adipokines and intracellular fat content and high energy phosphates in soleus muscle will be documented in healthy individuals, while no significant relation will be found in patients with type 2 diabetes. |
||||
Detailed Description | 10-15 patients with type 2 diabetes and 10-15 healthy control subjects will be examined on an outpatient basis. The following examination will be carried out in each subject after 12 hrs fasting:
Before (0 min), at 30 min and in the end of studies c) and d) the blood samples will be taken and biopsies of subcutaneous abdominal adipose tissue will be done. |
