Prevalence of masked hypertension in children with chronic kidney disease: a cross-sectional study.

BACKGROUND

Hypertension poses a significant risk as a complication of chronic kidney disease (CKD), contributing to its hastened advancement. Implementing ambulatory blood pressure monitoring (ABPM), a straightforward and non-invasive method proves beneficial in identifying masked hypertension.

METHODS

A cross-sectional study was carried out involving children aged 5-15 years diagnosed with CKD to estimate the difference in masked HTN prevalence between the 2014 and 2022 AHA ABPM guidelines. The study encompassed a comprehensive assessment, including 24-h blood pressure monitoring and was performed using ABPM. Left ventricular mass (LVM) was computed based on measurements obtained from M-mode echocardiography. PWV was determined by calculating the ratio of distance (D) to time (t).

RESULTS

We examined a cohort of 138 children diagnosed with CKD. Our findings reveal that, in accordance with the 2022 American Heart Association (AHA) ABPM guidelines, prevalence of masked hypertension stands at 29.7% marking a notable increase of 17.4% compared to the 2014 ABPM guidelines signifying a substantial proportion of undetected hypertensive cases. Furthermore, the prevalence of hypertension is 48.5% as detected by ABPM, marking a notable increase of 22.5%.

CONCLUSIONS

A substantial occurrence of masked hypertension was identified in pediatric CKD patients through the application of ABPM. ABPM proves to be an effective tool for uncovering masked hypertension in children with CKD.
