Abstract:
Objective:To investigate the features and advantages of ambulatory blood pressure monitoring (ABPM) applied in children with kidney diseases as well as the correlation between ambulatory blood pressure and clinical indicators.Methods:The clinical data of children with kidney diseases who were hospitalized and received ABPM in Children′s Hospital Affiliated to Capital Institute of Pediatrics from March 2012 to March 2018 were collected.Clinical blood pressure and ABPM indicators were analyzed and compared between different clinical groups.Results:(1) Among 170 cases enrolled, 69 cases (40.6%) were hypertension by measuring clinical blood pressure, 54 cases (31.8%) were ambulatory hypertension, 43 cases (25.3%) of whom had severe ambulatory hypertension, 17 cases (10.0%) had white coat hypertension, 41 cases (24.1%) were defined as masked hypertension, and 139 cases (81.8%) had impaired circadian rhythm of blood pressure.(2) Ninety-five point nine percent (163/170 cases) were detected of abnormal blood pressure by ABPM, and the rate was significantly higher than that detected by clinical blood pressure (40.6%, 69/170 cases) ( χ2=149.176, P<0.001). In the 40 cases who were administrated with antihypertensive drugs, 95.0%(38 cases) were detected to have anomalous blood pressure by ABPM, significantly more than that detected by clinical blood pressure(42.5%, 17/40 cases)( χ2=10.208, P=0.001). (3) Logistic regression analysis indicated that a prolonged clinical course of more than 3 months, obesity and nephrotic-range proteinuria were the risk factors of ambulatory hypertension, and the odd ratios were 5.345, 3.530 and 6.560, respectively.Circadian rhythm disorders of blood pressure were more common in the children with abnormal renal function than in those with normal renal function[89.7%(52/58 cases) vs.75.9%(85/112 cases)], and the difference was statistically significant ( χ2=4.626, P=0.031). Conclusions:Children with kidney diseases have a high incidence of hypertension.ABPM plays a key role in detecting hypertension and recognizing white coat hypertension.Nephrotic-range proteinuria and obesity are risk factors for ambulance hypertension, and abnormal renal function is associated with nocturnal blood pressure disorders.
