There is a growing number of patients with type 2 diabetes mellitus. As a component of the metabolic syndrome, type 2 diabetes is often associated with hyperuricemia and gout. These diseases worsen prognosis of concomitant cardiovascular disorders.
To assess the relationship between adiponectin and leptin levels and echocardiographic parameters in patients with type 2 diabetes mellitus, gout, and a combination thereof.
The study involved 30 men aged 41 to 70 years divided into 3 groups. The first group included 10 patients with type 2 diabetes, the second one 10 patients with gout, and the third group consisted of 10 men with a combination of type 2 diabetes and gout. In all patients the levels of glucose, immunoreactive insulin, HOMA-IR, adiponectin, and leptin were measured. All patients underwent echocardiography.
The study revealed hyperglycemia in patients with type 2 diabetes and its combination with gout. Patients of all three groups had increased insulin resistance, insulin and leptin levels, decreased concentration of adiponectin. The thickness of interventricular sepum in systole and diastole, posterior wall of the left ventricle in diastole, myocarduial mass of the left ventricle, the size of the left atrium and the right ventricle increased in patients of all three groups.
The study demonstrated compensatory hyperinsulinemia and insulin resistance, hypoadiponectinemia, hyperleptinemia, left ventricular hypertrophy, diastolic dysfunction, and intact ventricular contractility in patients with type 2 diabetes, gout, and their combination. Hypoadiponectinemia and hyperleptinemia play a role in remodeling of myocardium in these patients.
