Central Blood Pressure and Pulse Wave Velocity in Kidney Transplant Recipients
August 28, 2023 updated by: Asha Moudgil, Children's National Research Institute
Central Blood Pressure and Pulse Wave Velocity in Children With and Without Kidney Transplants
An observational cohort study will be conducted to non-invasively investigate central blood pressure and pulse wave velocity in children with kidney disease and controls.
Using an oscillometric monitor, the investigators aim to non-invasively obtain the central blood pressure and pulse wave velocity (PWV), or arterial stiffness, of children with kidney disease.
The investigators will also enroll age- and race-matched healthy controls and measure the same parameters for comparison.
In addition, the investigators will measure PWV by standard arterial tonometry method in a subset of patients.

Detailed Description
The specific aims of the study are as follows:
- Using an oscillometric blood pressure monitor, the investigators aim to non-invasively obtain the central blood pressure and pulse wave velocity (PWV), or arterial stiffness, of children with kidney disease.
- Measure oscillometric central blood pressure and PWV in age and race matched healthy children.
- Measure PWV by standard arterial tonometry method in a subset of patients, and compare these measurements to the PWV measured using the oscillometric device.
- Measure body composition of patients and controls (Body Mass Index, Waist-to-Height ratio, %body fat, and mid-arm muscle circumference) to see how this relates to central blood pressure and PWV.
