Chronotherapy in Children With Chronic Kidney Disease
Investigating if Nocturnal Blood Pressure Patterns Are Modifiable in Children With Chronic Kidney Disease
Study Overview

Intervention / Treatment
Detailed Description
Normally blood pressure declines by at least 10% from daytime to nighttime. In children with chronic kidney disease (CKD), often this does not happen (termed "non-dipping"). This study is a pilot, randomized cross-over trial. The main purpose of this study is to investigate whether non-dipping can be modified with retiming of anti-hypertensives in children with CKD. This is important because in adults, non-dipping has been associated with increased cardiovascular disease risk and more rapid progression of kidney disease. Thus, identification of how to modify this in children with CKD, may lead to future randomized controlled trials to evaluate whether chronotherapy improves outcomes in this population, which is at high risk for morbidity and mortality in adulthood.
The primary objective of this study is to determine whether retiming of one anti-hypertensive to the evening will increase nocturnal systolic blood pressure change (%) in children with CKD, hypertension and non-dipping.
The secondary objective of this study is to determine whether retiming of one anti-hypertensive to the evening will increase nocturnal diastolic blood pressure change (%) in children with CKD, hypertension and non-dipping. Another secondary objective is to determine if the proportion of subjects classified as having a non-dipping pattern is significantly lower on evening dosing of anti-hypertensives.

Participation Criteria
Eligibility Criteria
Ages Eligible for Study
Accepts Healthy Volunteers
Description
Inclusion Criteria:
- Male or female child/adolescent up to 18 years of age with CKD
- estimated glomerular filtration rate (eGFR) of 30 to 90 ml/min/1.73 m2
- diagnosed with hypertension and on a stable dose of anti-hypertensive medication(s) for at least 3 months
- Non-dipping identified on ABPM
Exclusion Criteria:
- history of organ transplantation, oncological disease, or dialysis
- inability to complete 24-hour ABPM or 24-hour urine collection
- Children less than 6 years of age will be excluded, as they often are unable to complete a successful ABPM study (≥ 40 readings, with 1 reading per hour of sleep)
- Currently on diuretic medications.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: nighttime dosing of one anti-hypertensive medication
13 participants will be randomized to nighttime dosing of one anti-hypertensive medication.
After 1 week, a repeat ABPM will be obtained.
At 1 month from randomization, another ABPM will be obtained.
Following this, there will be a 2-week washout period, during which all subjects will be on their usual anti-hypertensive regimen.
A repeat ABPM will be obtained after the washout period.
Next, the subjects will crossover to the opposite arm and an ABPM will be obtained after 1 week.
A final ABPM will be obtained at 1 month after crossover.
|
The intervention will consist of shifting the anti-hypertensive medication from morning/early dose to an evening/later dose
|
Active Comparator: remain on their current regimen
13 participants will be randomized to remain on their current regimen.
After 1 week, a repeat ABPM will be obtained.
At 1 month from randomization, another ABPM will be obtained.
Following this, there will be a 2-week washout period, during which all subjects will be on their usual anti-hypertensive regimen.
A repeat ABPM will be obtained after the washout period.
Next, the subjects will crossover to the opposite arm and an ABPM will be obtained after 1 week.
A final ABPM will be obtained at 1 month after crossover.
|
The participants will begin on their current regimen.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Percent change in nocturnal systolic blood pressure in participants administered anti-hypertensive medications at night on Ambulatory blood pressure monitor(ing) (ABPM).
Time Frame: Baseline and Month 1
|
Percent change in systolic nocturnal blood pressure will be calculated as : (daytime mean SBP - nighttime mean SBP)/daytime mean SBP x 100 to assess if nocturnal BP dipping can be restored.
|
Baseline and Month 1
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Percent change in nocturnal diastolic blood pressure in participants administered anti-hypertensive medications at night on ABPM.
Time Frame: Baseline and Month 1
|
Percent change in systolic nocturnal blood pressure will be calculated as: (daytime mean DBP - nighttime mean DBP)/daytime mean DBP x 100 to assess if nocturnal BP dipping can be restored.
|
Baseline and Month 1
|
Change in proportion of participants with restoration of dipping while on the intervention, defined as <10% systolic or diastolic nocturnal blood pressure change
Time Frame: Baseline and Month 1
|
This outcome will assess if the proportion of subjects classified as having a non-dipping pattern is significantly lower on evening dosing of anti-hypertensives.
Restoration of dipping would mean that both systolic and diastolic nocturnal blood pressure change are greater than or equal to 10%, after the intervention.
