Open Access Antihypertensive Treatment and Kidney Function in Routine Practice in Patients with Type 2 Diabetes Mellitus: The Results of the Prospective

Abstract: Background: Hypertension, albuminuria and decreased GFR are regarded as independent risk factors that reflect progression of the diabetic kidney disease (DKD). We carried out second phase of prospective study which aim was to learn the possibility of implementation of intensive antihypertensive therapy into the routine clinical practice and assessment of such treatment influence on kidney function in patients with type 2 diabetes mellitus (T2DM). Methods: In the study 637 patients were included with DKD and arterial hypertension with BP level more than 130/80 mmHg and less than 180/100 mmHg, having chronic kidneys disease (CKD) 1-4. As a basis for intensive antihypertensive treatment fixed combination of perindopril 5 mg and indapamide 1.25 mg were prescribed. If needed, after 4 weeks the dosage was increased up to perindopril 10 mg / indapamide 2.5 mg to achieve targeted BP less that 130/80 mmHg. If targeted BP had not been achieved other antihypertensive preparations were added. Results: After 4 weeks of treatment average levels of systolic and diastolic BP were 141.3±0.5 and 86.3±0.3, after 8 weeks of therapy – 131.6±0.4 and 81.3±0.3 mmHg, and after 12 weeks of treatment –127.2±0.3 and 78.7±0.2 mmHg respectively. Target BP was achieved in 489 patients (73.3%) during 12 weeks of treatment. Statistically significant increase of GFR as a result of 12 weeks of antihypertensive therapy with fixed perindopril/indapamide combination was found to be between 84.3±1.1 and 94.7±1.1 ml/min./1,73m2, р<0.01. Conclusion: Antihypertensive therapy with fixed combination of perindopril 5-10 mg/indapamide 1.25-2.5 mg introduce
