Objectives: The aim of this study was to assess blood pressure (BP) control in patients with chronic kidney disease (CKD) according to office and home BP and to assess the prevalence of normal BP, white-coat uncontrolled hypertension (WUCH), masked uncontrolled hypertension (MUCH) and elevated BP., Methods: Patients with renal failure with or without proteinuria were included in this multicenter observational study. Office BP was first measured by the physician using a self-monitoring BP device (three automatic readings), then by the patient at home (morning and evening) over 3 consecutive days. WUCH was defined as a systolic BP (SBP)/diastolic BP (DBP) ≥140/90 mmHg in the clinic and SBP/DBP<135/85 mmHg at home. MUCH was defined as SBP/DBP <140/90 mmHg in the clinic and SBP/DBP ≥135/85 mmHg at home., Results: Among the 243 included subjects, data of 225 patients were analyzed. Mean estimated glomerular filtration rate was 37.7 ± 15.7 mL/min/1.73 m and mean office SBP/DBP was 154 ± 19/83 ± 13 mmHg. Mean office SBP/DBP was significantly higher than home SBP/DBP (+9.0 ± 15.1/+7.0 ± 10.0 mmHg, P < 0.01). Normal BP (office and home BP), WUCH, MUCH and elevated BP (office and home BP) rates were 12.0, 14.2, 6.7 and 67.1%, respectively. The patients were taking, on average, 2.8 ± 1.5 antihypertensive drugs/day., Conclusion: BP control in patients with CKD was poor. Routine use of 'out-of-office' BP measurement, in addition to office BP by which we can identify patients with WUCH or MUCH, should be recommended based on the current findings.

Objectives: To compare home blood pressure (BP) values obtained with two validated OMRON (wrist or arm) monitors used in the same individual sequentially, but with two different hand positions., Methods: In 200 hypertensive individuals referred to hypertension specialists, a self-measurement of BP was performed sequentially with an OMRON M4-I (arm cuff, A/A, British Hypertention Society validation) and an OMRON RX-I (wrist cuff, B/B, BHS validation). Each patient recorded home BP during two periods of 4 days with three measures in the morning and three in the evening. Order for use of each monitor was randomized. For the first 100 patients, the hand was positioned on the opposite shoulder whereas for the next 100 patients, the hand was positioned on the opposite elbow. BP values were reported on a standardized document., Results: In this population, aged 60+/-10 years, with 54% of men, BP values were 136+/-/80+/- mmHg with the wrist monitor (WM) when the hand is positioned on the opposite shoulder as compared with 144+/-16/81+/-9 mmHg obtained with the arm monitor taken as the gold standard. On the contrary, BP values were 142+/-/82+/- mmHg with the WM when the hand is positioned on the opposite elbow as compared with 144+/-16/81+/-9 mmHg obtained with the arm monitor. The lower value of systolic blood pressure observed with WM positioned on the shoulder is independent of age, initial BP level and order of use (multivariate analysis)., Conclusion: When advising home BP monitoring with a WM, the instruction to be given to patients is to position the hand on the opposite elbow.
