Clinical Trial Summary

The goal of this observational study is to evaluate, between patients with arterial hypertension and non hypertensive control group, - the prevalence of hidden hypercortisolism - the relationship between organ damage and oxidative stress level, cortisol secretion degree, sensitivity and peripheral activity

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Prevalence of hidden hypercortisolism (HidHyCo)	The presence of HidHyCo will be evaluated through the determination of cortisol levels at 9.00 am after taking 1 mg of dexamethasone the previous evening at 11.00 pm (1mgDST). In case of 1mgDST >1.8 µg/dL the patient will repeat the test and, if the result is confirmed, the patients is considered to have HidHyCo.	At baseline
Secondary	Evaluation of organ damage	Organ damage will be assessed by performing echocardiography, carotid echo-doppler (arterial stiffness) and microalbuminuria evaluation, which assess hypertensive heart disease, macro-angiopathy and hypertensive nephropathy, respectively	At baseline
Secondary	Evaluation of oxidative stress level	The determination of the degree of oxidative stress will be carried out in all patients by evaluating the enzymatic activity of dipeptidyl peptidase 3 (DPP3) in the serum	At baseline
Secondary	Evaluation of cortisol secretion degree	The cortisol secretion will be evaluated by measuring morning plasma ACTH and serum cortisol, 24-hour urinary free cortisol, serum cortisol at 09:00 after the administration of; 1 mg dexamethasone at 11 PM on the previous day	At baseline
Secondary	Evaluation of glucocorticoid sensitivity	In all subjects, genotyping of the N363S, BclI, ER22/23EK polymorphisms of the GR gene and of the polymorphisms will be performed	At baseline
Secondary	Evaluation of glucocorticoid peripheral activity	Urinary free cortisol and urinary free cortisone will be measured in all subjects; their ratio will be used as measure of glucocorticoid peripheral activity	At baseline
