Assessment of renal and cardiovascular risks in patients with type 2 diabetes when using non-steroidal mineralocorticoid receptor antagonists
Abstract
Background. Given the proven excessive activation of the renin-angiotensin-aldosterone system and the clinical manifestations of hypertension, mostly of renal origin, there is a need to optimize antihypertensive therapy aimed at an active nephroprotection. The purpose of the study is to carry out a comprehensive assessment of kidney and heart risk factors in patients with type 2 diabetes mellitus and chronic kidney disease (CKD) and to justify the administration of non-steroidal mineralocorticoid receptor antagonists to these patients. Materials and methods. In a prospective cohort study, 88 patients with type 2 diabetes were examined: group 1 — estimated glomerular filtration rate (eGFR) < 60 ml/min/m2, group 2 — eGFR ≥ 60 ml/min/m2. eGFR was evaluated according to the CKD-EPI (Chronic Kidney Disease Epidemiology Collaboration) formula based on serum creatinine. GFR category was defined according to the KDIGO (Kidney Disease: Improving Global Outcomes) criteria. The albumin-creatinine ratio was calculated. The level of glycated hemoglobin (HbA1c) was assessed by the method of high-performance liquid chromatography. Aldosterone was evaluated by immunoenzymatic method. Results. In patients with eGFR < 60 ml/min/m2, the albumin-creatinine ratio in daily urine is statistically significantly higher compared to group 2. Patients with eGFR < 60 ml/min/m2 had an average uric acid level of 410.3 ± 98.8 μmol/l, which is statistically significantly higher than in those with eGFR ≥ 60 ml/min/m2 — 321.10 ± 74.54 μmol/l. A statistically significant correlation between the level of uric acid and markers of renal dysfunction was found only in patients with eGFR < 60 ml/min/m2. Aldosterone levels were higher in the first group. No statistical difference was found between the average value of HbA1c in the studied groups. Conclusions. Numerous factors of unfavorable prognosis regarding kidney and heart risks have been identified: hypertension, increased albumin-creatinine ratio and cholesterol, unsatisfactory compensation of diabetes, obesity. There is an increase in the frequency of resistant hypertension, hyperuricemia, and hyperaldosteronism in patients with decreased eGFR. In patients with diabetic kidney damage on the background of type 2 diabetes, the administration of finerenone, a non-steroidal mineralocorticoid receptor antagonist, at a dose of 10–20 mg/day is pathogenetically justified.
