Study summary

What the protocol is testing.

Women with androgen excess polycystic ovary syndrome (AE-PCOS) leads to hypertension.

Full detailed description

Our scientific premise is that in AE-PCOS women, the androgen-dominant hormonal milieu causes BP increases via sympathetic activation, vasoconstriction and renal sympathetic nervous system activation. Moreover, this androgen-dominant milieu increases BP via activation of the renin-angiotensin system.

Outcomes

What the study measures.

Primary outcomes

Baroreflex Response to LBNP

Time frame · Baseline, assessed at 7 days of GnRH, assessed at 16 days GnRH+ 5 days of Testosterone

forearm blood flow (ultrasound)/mean arterial pressure as a linear function of lower body negative pressure. This is an important measure of autonomic control of blood pressure. Indicating the the sensitivity of changes in vessel diameter in response to blood pooling (induced by lower body negative pressure).

Free Plasma Testosterone Levels

Time frame · Baseline, assessed at 7 days of GnRH, assessed at 16 days GnRH+ 5 days of Testosterone

Concentration of testosterone in blood.

Renal Response to LBNP

Time frame · Baseline, assessed at 7 days of GnRH, assessed at 16 days GnRH+ 5 days of Testosterone

POST Lower body negative pressure Plasma renin activity

Renal Responses to LBNP

Time frame · Baseline, assessed at 7 days of GnRH, assessed at 16 days GnRH+ 5 days of Testosterone

PRE lower body negative pressure Plasma renin activity

Resting Systolic Blood Pressure

Time frame · Baseline, assessed at 7 days of GnRH, assessed at 16 days GnRH+ 5 days of Testosterone

Blood pressure prior to lower body negative pressure

Final Systolic Blood Pressure

Time frame · Baseline, assessed at 7 days of GnRH, assessed at 16 days GnRH+ 5 days of Testosterone

SBP at the end of lower body negative pressure

Resting Sympathetic Activity

Time frame · Baseline, assessed at 7 days of GnRH, assessed at 16 days GnRH+ 5 days of Testosterone

Total sympathetic nerve activity

Sympathetic Baroreflex

Time frame · Baseline, assessed at 7 days of GnRH, assessed at 16 days GnRH+ 5 days of Testosterone

microneurography, diastolic blood pressure (finipres) This is an important measure of autonomic control of blood pressure. Indicating the the sensitivity of changes in muscle sympathetic nerve activity in response to small changes in blood pressure induced by drug perfusion (modified Oxford).

Secondary outcomes

Aldosterone

Time frame · Baseline, assessed at 7 days of GnRH, assessed at 16 days GnRH+ 5 days of Testosterone

Plasma aldosterone concentration

Renal Responses

Time frame · Baseline, assessed at 7 days of GnRH, assessed at 16 days GnRH+ 5 days of Testosterone

P\[ACE\], angiotensin-converting enzyme
