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

---|---|---|---|---|
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 |
