Comparison between home and clinic blood pressure measurement in hypertensive chronic kidney disease patients

Background Hypertension is common in chronic kidney disease (CKD), and white coat hypertension (WCH) complicates its diagnosis and treatment. Patients and methods We conducted a cross-sectional study of 66 CKD patients with uncontrolled clinic blood pressure (BP) at the nephrology outpatient clinic at Suez Canal University Hospital, comparing home and clinic BP readings to detect WCH. Results The mean clinic systolic BP (167.2 ± 13.7 mmHg) was significantly higher than the mean home systolic BP (131 ± 12.5 mmHg) ( P <0.005). WCH was identified in 65.2% of patients and was significantly associated with diabetes (odds ratio: 4.92; 95% confidence interval: 1.34–18.15). Conclusions WCH is highly prevalent, affecting nearly two-thirds of CKD patients with elevated clinic BP, highlighting the need for routine home BP monitoring for accurate diagnosis and individualized management.
