Objective: The aim of the study was to evaluate the 24-h profile of peripheral and central blood pressure (BP) in hypertensive patients with type 2 diabetes mellitus (T2DM) and chronic kidney disease (CKD) according to the presence of proteinuria. Design and method: The study included 90 patients with HTN, T2DM and CKD with eGFR 30-<60 ml/min/1.73 m2 and urine albumin–creatinine ratio (UACR) <300 mg/g (66% females, median age 60 years, median duration of DM–7.5 years, median duration of HTN 18 years). All received antihypertensive therapy and antidiabetic drugs (insulin in 58%). The analysis was performed according to CKD phenotype: proteinuric (UACR 30-<300 mg/g) and non-proteinuric (UACR < 30 mg/g). Office BP was measured with a validated oscillometric device. Clinical central BP and 24-hour ABPM of brachial and central aortic BP were performed with BPLab Vasotens. All results are presented as median values. p < 0.05 was considered significant. Results: Office brachial BP was 156/83 mmHg, aortic – 139/90 mmHg, median UACR was 26.5 mg/g. Proteinuric phenotype was found in 78% and compared to non-proteinuric phenotype was characterized by higher rate of dyslipidemia (85% vs 45%, p = 0.0004), more frequent history of coronary artery disease (53% vs 10%, p = 0.001), longer duration of HTN and DM (19.5 vs 7.5 years and 8 vs 3 years respectively, p < 0.01), lower HDL-C (1.2 vs 1.9, p = 0.02) and higher office brachial DBP (83 vs 80 mmHg, p = 0.04) and central SBP (147 vs 137 mmHg, p = 0.007). Proteinuric phenotype compared to non-proteinuric was associated with worse 24-h profile of central SBP (daytime 147 vs 138 mmHg, p = 0.008; night-time 143 vs 130 mmHg, p = 0.04). HTN phenotypes according to diurnal index for proteinuric and non-proteinuric CKD were as follows: dippers 0 vs 10%, non-dippers 6 vs 5%, night-peakers 82 vs 70% over-dippers 12 vs 15% (all differences were non-significant). Presence of proteinuric phenotype positively correlated with daytime and night-time aortic SBP (r = 0.28 and 0.21 respectively, p < 0.05). Conclusions: Proteinuric phenotype of CKD in patients with HTN and T2DM is associated with worse 24-h profile of central BP. The publication was prepared with the of the RUDN University Program 5-100
