Filter by:The purpose of this study is to evaluate the serum dehydroepiandrosterone sulfate in subclinical hypercortisolism
The data on long term natural history of benign nonfunctioning adrenal tumors (NFATs) are lacking. The aim is to identify clinical characteristics associated with tumor growth and progression to mild autonomous cortisol excess over time.
This pilot study wants to determine to which extent SPCCT allows obtaining images with improved quality and diagnostic confidence when compared to standard Dual Energy CT (DECT), both with and without contrast agent injection. Depending on the anatomical structures/organs to be visualized during CT examinations, different scanning protocols are performed with quite variable ionizing radiation doses. Therefore, in order to obtain the most extensive and representative results of the improvement in image quality between SPCCT and DECT that will be performed CT imaging on several body regions and structures, including diabetic foot, diabetic calcium coronary scoring, adrenal glands, coronary arteries, lung parenchyma, kidney stones, inner ear, brain and joints, earl/temporal bone, colorectal carcinosis.
The investigators hypothesize that cardiovascular and metabolic alterations can occur in patients with adrenal adenomas and possible Autonomous Cortisol Secretion (pACS). Investigators hypothesize that adrenalectomy in selected patients, following the 2016 ECE guidelines, can improve metabolic parameters and cardiovascular risks and features.
Standard diagnostic work-up for adrenal incidentalomas (AI) consists of periodical biochemical analysis and CT-scanning in case the initial work-up does not demonstrate the presence of hormonal hypersecretion or adrenocortical carcinoma (ACC), respectively. The overall aim of this study is to improve the cost-effectiveness of the diagnostic strategy for AI. Cost-effectiveness of urine steroid profiling (USP) will be compared to the standard diagnostic strategy of repeated CT-imaging.
Background: The evaluation for hypercortisolism includes an overnight 1mg dexamethasone (DXM) suppression test. An important shortcoming is the diagnostic specificity of only 80%, which is likely due to inter-individual differences in gut absorption or metabolism of DXM. Study hypothesis: The investigators hypothesize that serum-DXM measurements will increase the diagnostic accuracy of the overnight DXM-test in the work-up of hypercortisolism. Aims: The primary aim of this prospective study is to evaluate if serum-DXM measured simultaneously with serum-cortisol in morning samples could increase the diagnostic accuracy this diagnostic test. There are several secondary aims. One is to estimate the prevalence and causes of unusual DXM absorption or metabolism. The investigators will also evaluate the feasibility and diagnostic accuracy of salivary DXM. Moreover, the diagnostic accuracy of midnight salivary cortisol and cortisone, and urinary cortisol, will be evaluated and compared. Design: Levels of DXM in morning serum following an overnight DXM-test will be analyzed in patients under evaluation for hypercortisolism (including incidentalomas). A cut-off level to identify inadequate DXM concentrations in serum to suppress endogenous cortisol production will be established based on the negative tests. This cut-off level will then be applied in a retrospective analysis of the diagnostic accuracy of DXM-tests. This prospective study has a blinded design as the DXM measurements are disclosed after the end of the trial.
Objective: To determine the metabolic effects of the adrenalectomy in subclinical Cushing's syndrome of adrenal incidentaloma. Methods: 234 subclinical cushing syndrome and adrenal incidentaloma will be randomly assigned into two groups(e.g adrenalectomy group and conservative treatment group).
