Adrenal Insufficiency Clinical Trial
Official title:
Clinical Study on Circadian Genes Dysregulation in Patients With Glucocorticoid Disorders
This is a multicentric, prospective, intervention study on circadian genes expression in peripheral blood mononuclear cells as biomarkers of circadian rhythm derangement in patients affected by alterations of endogenous glucocorticoids secretion (Cushing's Syndrome during active phase, treatment and under remission and newly or on established glucocorticoid replacement therapy adrenal insufficiency)
This is an intervention, prospective, multicentric study. Enrolled patients will undergo 4 visits: - Adrenal insufficiency (AI) patients: patients affected by primary or secondary adrenal insufficiency, whether newly diagnosed or on established glucocorticoid therapy, will be evaluated at baseline and after one, three and six months. - Cushing's Syndrome (CS) patients: patients affected by Cushing's Syndrome will be evaluated at baseline during active phase of the disease and one, three and six months after treatment or remission. Patients affected by Cushing's Syndrome who will require glucocorticoid replacement therapy after remission will be evaluated three and six months after remission and then three and six months after the eventual glucocorticoid replacement therapy withdrawal. CS treatment will be surgery or medical therapy according to guidelines. Timing of medical therapy administration will change during protocol according to circadian rhythms. Age-, sex- and BMI- matched healthy controls will be enrolled. Patients and controls will undergo the same procedures at baseline and after 1, 3 and 6 months. The primary outcome measure will be the evaluation of circadian genes CLOCK and Aryl Hydrocarbon Receptor Nuclear Translocator Like (ARNTL) expression in peripheral blood mononuclear cells (PBMC) compared to healthy controls. Secondary Outcomes measures will be: - Circadian genes expression assessment compared to healthy controls at 7:00-8:00 Ante Meridiem (AM) (before breakfast), 12:00 AM (before lunch), 3:00-4:00 Post Meridiem (PM) (after lunch), 7:00 PM (before dinner), 12:00 PM; - Immune profiling compared to healthy controls by the quantification of peripheral blood mononuclear cells (PBMC) subpopulations assessed by flow cytometry at 7:00-8:00 AM (before breakfast), 12:00 AM (before lunch), 3:00-4:00 PM (after lunch), 7:00 PM (before dinner), 12:00 PM; - Evaluation of inflammatory cytokines and adipokines production compared to healthy controls at 7:00-8:00 AM (before breakfast), 12:00 AM (before lunch), 3:00-4:00 PM (after lunch), 7:00 PM (before dinner), 12:00 PM; - Circadian cortisol rhythm by serum and salivary dosage at 7:00-8:00 AM (before breakfast), 12:00 AM (before lunch), 3:00-4:00 PM (after lunch), 7:00 PM (before dinner), 12:00 PM; - Sleep disturbances evaluation by The Pittsburgh Sleep Quality Index (PSQI) self reported questionnaire - Evaluation of infectious diseases frequencies and severity compared to healthy controls. Infectious diseases will be evaluated by an adaptation of Infectious Diseases Questionnaire (GNC) - Circadian blood pressure using ambulatory blood pressure monitoring blood pressure waves for a noninvasive estimation - Quality of life using SF-36-Item Health Survey questionnaire - Psychometric Evaluation using Beck Depression Inventory questionnaire - Evaluation of sexual dysfunction using FSFI questionnaire in woman and IIEF questionnaire in man - Evaluation of insuline resistance calculated with HOMA index - Evaluation of body weight (kg) - Evaluation of blood lipid profile ;
