Abstract

Objective. To evaluate the role of the T(-344)C polymorphism of CYP11B2 gene in the development of cardiorenal syndrome (CRS) in diabetes mellitus (DM).Materials and methods. 270 patients with type 1 and type 2 diabetes aged over 25 years were examined. All patients underwent molecular genetic analysis using deoxyribonucleic acid isolated from whole venous blood.Results. The TT genotype was associated with the risk of developing CRS manifestations such as left ventricular hypertrophy (odds ratio (OR) 2.64; 95% CI (0.93–4.19), chronic heart failure (OR 4.26; 95% CI (2.26 - 8.06), subclinical atherosclerosis (OR 4.04; 95% CI (1.89 - 8.58), chronic kidney disease (CKD) (OR 10.77; 95% CI (3.56 - 32.61), and the CT genotype (OR 3.28; 95% CI (1.02 – 10.59) with CKD risk..Conclusion. There are pathogenetic associations between renin-angiotensin-aldosterone system, cardiovascular complications and a decrease of renal function. Further research is needed for a deep understanding of the complex pathogenetic mechanisms of the development and progression of cardiovascular and renal pathology.
