Pediatric Hypertension and the Renin-Angiotensin SystEm (PHRASE): The Role of Angiotensin-(1-7) in Hypertension and Hypertension-Induced Heart and Kidney Damage
Wake Forest University Health Sciences
Summary
Studying the causal roles of components of the renin-angiotensin-aldosterone system (including angiotensin-(1-7) (Ang-(1-7)), angiotensin-converting enzyme 2 (ACE2), Ang II, and ACE), uric acid, and klotho in pediatric hypertension and related target organ injury, including in the heart, kidneys, vasculature, and brain. Recruiting children with a new hypertension diagnosis over a 2-year period from the Hypertension and Pediatric Nephrology Clinics affiliated with Brenner Children's Hospital at Atrium Health Wake Forest Baptist and Atrium Health Levine Children's Hospital. Healthy control participants will be recruited from local general primary care practices. Collecting blood and urine samples to analyze components of the renin-angiotensin-aldosterone system (Ang-(1-7), ACE2, Ang II, ACE), uric acid, and klotho, and measuring blood pressure, heart structure and function, autonomic function, vascular function, and kidney function at baseline, year 1, and year 2. Objectives are to investigate phenotypic and treatment response variability and to causally infer if Ang-(1-7), ACE2, Ang II, ACE, uric acid, and klotho contribute to target organ injury due to hypertension.
Description
This longitudinal prospective cohort study is recruiting children and adolescents aged 7-18 years with newly diagnosed primary hypertension over a 2-year period from the Hypertension and Pediatric Nephrology Clinics affiliated with Brenner Children's Hospital at Atrium Health Wake Forest Baptist, which sees over 300 new patients a year, and the Pediatric Nephrology Clinic at Atrium Health Levine Children's Hospital (Hypertension Cohort). Also recruiting healthy control participants aged 7-18 years with normal blood pressure from local primary care practices (Control Cohort). Collecting blood a…
