Brief Summary:
Benign enlargements of the adrenal glands adrenal adenomas are frequent in adults In the general population these adenomas are rare in subjects below 40 years of age but at the age of 60 and 80 years the prevalence is 6 and 8-10 respectively Since these adenomas do not causes obvious symptoms they are almost exclusively found incidentally in patients examined radiologically for other reasons than suspected adrenal disease These enlargements are thus termed adrenal incidentalomas AI AI may secrete cortisol and more than 25 percent of patients with an AI have increased cortisol levels called autonomous cortisol secretion ACS Such increased secretion of cortisol may cause metabolic complications such as hypertension high cholesterol diabetes and cardiovascular disease Studies have shown that ACS may cause increased mortality These studies are however small and have not adequately taking other conditions into account which most likely influences the result
The investigators hypothesis is that ACS is linked to increased mortality as the previous studies have shown The aim is to perform a larger study on patients with adrenal incidentalomas both with and without ACS and compare the mortality rates with a control group matched for age and sex This study may more precisely describe the cardiovascular risk for ACS and define the risk at different levels of ACS
The investigators hypothesis is that ACS is linked to increased mortality as the previous studies have shown The aim is to perform a larger study on patients with adrenal incidentalomas both with and without ACS and compare the mortality rates with a control group matched for age and sex This study may more precisely describe the cardiovascular risk for ACS and define the risk at different levels of ACS
Detailed Description:
Patients with adrenal adenomas may have autonomous cortisol secretion ACS that has been linked to hypertension diabetes dyslipidemia and cardiovascular disease Patients with ACS also have been found to have increased mortality In two studies the excess mortality was caused by cardiovascular disease and in one study by cancer
ACS is diagnosed by increased cortisol 50 nmoll following 1-mg dexamethasone suppression DST often in combination with another confirmatory test such as low ACTH increased urinary cortisol increased midnight salivary cortisol or a dexamethasone suppression test with a higher dexamethasone dose Cortisol secretion from an AI has been considered exclusively autonomous but the investigators have recently shown that a large group of patients with normal results on DST have low ACTH indicating that another factor than ACS may suppress the HPA-axis The hypothesis is that these patients have an increased sensitivity to ACTH which results in lower ACTH levels It has however not been studied whether the increased sensitivity to ACTH is linked to increased cardiovascular morbidity and mortality
Patient data is collected from the patient cards and radiology images Patients are included according to the eligibility criteria The patients will be separated in the following groups
1 No ACS inhalation steroids or adrenalectomy
2 ACSpossible-ACS but not treatment with inhalation steroids or adrenalectomy
3 Treatment inhalation steroids but not operated
4 Unilateral AI and treated with adrenalectomy but no inhalation steroids The group is separated in patients without ACS and patients with possible ACSACS
Three age and gender matched subjects from the general population for every patient will serve as a controls
Outcome data on patients and controls is received from The National Board of Health and Welfare The control group is achieved from SCB Sweden Statistics Sweden The following outcome data will be collected Data on mortality cause of mortality and inpatient and outpatient cardiovascular diagnoses The study design reduces the risk for bias between the clinical endpoints and the patients cortisol and ACTH levels The patient cohorts will be finally defined before the investigators receive the clinical endpoints from The National Board of Health and Welfare
Statistical analysis The prevalence of the outcome data in the groups of patients will be compared The investigators will adjusted for differences between the groups in sex age smoking impaired renal function and existing cardiovascular disease
The following variables will be examined in relation to the outcome data Cortisol following dexamethasone 50 nmoll 83 nmoll and 138 nmoll low basal ACTH 20 pmoll DHEAS the size of the AI and bilateral versus unilateral AI
Study Status We anticipate to receive the outcome data from The National Board of Health and Welfare in October 2019 The study has thus been slightly delayed Data on morbidity will only be available until December 31 2017 due to a delay in reporting to The National Board of Health and Welfare The secondary outcome measure has been changed to a composite of cardiovascular endpoints
