Brief Summary:
The purpose of this research protocol is to determine if the same effects are observed in vivo in humans using a similar approach. Demonstrating that mineralocorticoid acts on zona glomerulosa cells to regulate aldosterone production in a short feedback loop would provide important insight into hormone regulation, and explain variability in pathophysiologic states such as hypertension and cardiovascular diseases.

Condition or disease Intervention/treatment Phase
Healthy Volunteers Drug: Placebo Drug: Fludrocortisone Drug: Eplerenone Phase 1

Detailed Description:
In order to provide additional evidence indicating the presence of functional and in order to provide additional evidence indicating the presence of functional mineralocorticoid receptors (MR) on zona glomerulosa (ZG) cells, the investigators propose the following protocol in healthy volunteers. The investigators will evaluate aldosterone and cortisol production in response to an angiotensin II infusion after three separate test conditions: 1) placebo, 2) following a single dose of fludrocortisone, and 3) following a single dose of eplerenone (a MR antagonist).

Ages Eligible for Study:   18 Years to 40 Years   (Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   Yes
Criteria

Inclusion Criteria:

  • Participants must be healthy, with no prior history of hypertension, no family history of hypertension, diabetes, stroke or cardiac disease in first-degree relatives before the age of 70 years and have an average (two measurements) blood pressure of <130/89 mm Hg and >100/50 mmHg at the screening visit.
  • All subjects will have body mass index 19-25 kg/m2.
  • Subjects must have normal laboratory values for: Complete blood count; serum creatinine, sodium, potassium, glucose, liver enzymes; urinalysis; negative urine HCG in women; normal ECG

Exclusion Criteria:

  • Alcohol intake >12oz per week, as well as tobacco or recreational drug use.
  • Any subject with a history of coronary disease, diabetes, hypertension, stroke, kidney disease, or illness requiring overnight hospitalization in the past 6 months will be excluded from the study.
  • Subjects taking any prescription medications (with the exception of birth control pills) or herbal medications will be excluded.
  • Because of the unknown risk of infused angiotensin II in pregnancy, women who are pregnant will be excluded from study and all women will be screened for pregnancy by quantitative serum hCG measurement on the day of each CCI admission.
  • Women currently breastfeeding will also be excluded from the study.
