Abstract
Adrenal incidentalomas have increased due to advanced and more sensitive imaging modalities, their increased utilization, and the aging population. Most adrenal incidentalomas are nonfunctional and benign, but a subset of patients has functional and/or malignant tumors. The evaluation of patients with an adrenal incidentaloma involves addressing 2 clinical questions: (1) Is the tumor functional? (2) Is the tumor malignant? A careful history and physical examination focused on signs and symptoms of adrenal functional tumors, biochemical testing, and imaging features are the cornerstone in the evaluation of patients with an adrenal incidentaloma.

Abstract
Endogenous Cushing's syndrome (CS) is a rare condition due to prolonged exposure to elevated circulating cortisol levels that features its typical phenotype characterised by moon face, proximal myopathy, easy bruising, hirsutism in females and a centripetal distribution of body fat. Given the direct and indirect effects of hypercortisolism, CS is a severe disease burdened by increased cardio-metabolic morbidity and mortality in which visceral adiposity plays a leading role. Although not commonly found in clinical setting, endogenous CS is definitely underestimated leading to delayed diagnosis with consequent increased rate of complications and reduced likelihood of their reversal after disease control. Most of all, CS is a unique model for systemic impairment induced by exogenous glucocorticoid therapy that is commonly prescribed for a number of chronic conditions in a relevant proportion of the worldwide population. In this review we aim to summarise on one side, the mechanisms behind visceral adiposity and lipid metabolism impairment in CS during active disease and after remission and on the other explore the potential role of cortisol in promoting adipose tissue accumulation.

Abstract
Mild autonomous cortisol secretion (MACS) is associated with a higher cardiometabolic risk than that observed in patients with nonfunctioning adrenal adenomas and in the general population. In patients with MACS, the excess of glucocorticoids affects various metabolic pathways, leading to different manifestations of metabolic syndrome and other comorbidities. Hypertension and diabetes mellitus are two of the most common cardiometabolic comorbidities associated with MACS, reaching a prevalence of up to 80% and up to 40%, respectively. In addition, they are the comorbidities that experienced a greater improvement after adrenalectomy in patients with MACS. Hypertension pathogenesis is multifactorial, including the coexistence of comorbidities such as obesity or diabetes and the role of the different polymorphisms of the glucocorticoid receptor gene, among others. Glucocorticoid-induced diabetes mellitus is mainly related to the detrimental effects of glucocorticoids on insulin-dependent glucose uptake in peripheral tissues, gluconeogenesis and insulin secretion. There are no specific recommendations for hypertension and diabetes treatment in patients with MACS. Thus, considering the similar underlying pathogenesis of hypertension and diabetes mellitus in overt and mild hypercortisolism, our recommendation is to follow this general stepwise approach: surgically remove the adrenal culprit lesion to induce remission from hypercortisolism; control hypercortisolism with steroidogenesis inhibitors; and treat elevated blood pressure or high glucose levels using carefully selected anti-hypertensives and glucose-lowering medications if blood pressure and glucose levels remain uncontrolled, respectively. In this review, we summarize the epidemiology, physiopathology and management of diabetes mellitus and hypertension in patients with MACS.

[PMID: 36800277 PMCID: PMC10348456 DOI: 10.1210/clinem/dgad074] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/06/2022] [Revised: 01/31/2023] [Accepted: 02/03/2023] [Indexed: 02/18/2023]
Abstract
CONTEXT Mild autonomous cortisol secretion (MACS) is associated with increased mortality in patients with adrenal incidentalomas, but little is known regarding the potential risk associated with nonfunctional adrenal adenomas (NFAA), which constitute the majority of adrenal incidentalomas. OBJECTIVE Compare mortality risk in patients with NFAA, and different levels of MACS, to matched controls. METHOD This was a retrospective matched cohort study. All patients referred to 2 endocrine centers in southern Sweden because of an adrenal incidentaloma between 2005 and 2015 were enrolled. Controls (3:1) matched for sex, age, and residency were included. Primary endpoint was all-cause mortality. Outcome data were obtained from the Cause of Death Register. Patients were grouped according to cortisol level post 1-mg dexamethasone suppression test (cortisolDST) (<50 (NFAA), 50-82, 83-137, and ≥138 nmol/L). RESULTS 1154 patients and 3462 matched controls were included. During a median follow-up of 6.6 years, 210 patients and 505 controls died. There were no statistically significant differences in mortality between patients with NFAA and their controls (HR 1.13 [0.87-1.46]) whereas mortality was increased compared to controls in patients with cortisolDST 83-137 (HR 1.99 [1.38-2.88]) and ≥138 nmol/L (HR 4.09 [2.41-6.93]). Likewise, the mortality risk was increased in patients younger than 65 years with cortisolDST 50-82 nmol/L compared with controls (HR 2.33 [1.30-4.17]). CONCLUSION NFAA does not seem to pose a clinically relevant risk for increased mortality in patients with adrenal incidentalomas while patients with MACS, and especially younger patients and those with cortisolDST ≥83 nmol/L, have significantly increased mortality risk compared with matched controls.

Abstract
Adrenal adenomas are incidentally identified in up to 5% of computer tomography scans performed for unrelated indications. A proportion of these adrenal incidentalomas are found to autonomously secrete cortisol based on definitions in current guidelines. Epidemiological studies suggest that chronic exposure to mild glucocorticoid excess from adrenal incidentalomas is associated with significantly increased cardiometabolic risk. However, current management guidelines adopt a conservative approach as no large prospective randomized studies have demonstrated that these patients benefit from surgery. This narrative review examines the epidemiological and mechanistic studies related to three common clinical settings of mild glucocorticoid excess to gain further insight into the potential benefits of treating patients with adrenal incidentaloma and possible autonomous cortisol secretion.

Abstract
Stress, in both intrinsic psychosocial and extrinsic physical environmental forms, can impact the development of, and outcomes in, cardiovascular disease (CVD) through allostatic load. Cortisol is a core hormonal mediator of allostatic load produced in response to various stresses. Alterations in morning serum cortisol and daily diurnal cortisol have been associated with adiposity, dyslipidemia, incident diabetes, and CVDs such as hypertension. The review examines the role of cortisol as a key mechanistic link between stress physiology and cardiometabolic disease. Importantly, we discuss the role of targeting cortisol through pharmacological, behavioral, and environmental interventions to advance health equity in cardiometabolic disease.

Abstract
Adrenal incidentalomas are incidentally discovered adrenal masses greater than one centimeter in diameter. An association between insulin resistance and adrenal incidentalomas has been established. However, the pathophysiological link between these two conditions remains incompletely characterized. This review examines the literature on the interrelationship between insulin resistance and adrenal masses, their subtypes, and related pathophysiology. Some studies show that functional and non-functional adrenal masses elicit systemic insulin resistance, whereas others conclude the inverse. Insulin resistance, hyperinsulinemia, and the anabolic effects on adrenal gland tissue, which have insulin and insulin-like growth factor-1 receptors, offer possible pathophysiological links. Conversely, autonomous adrenal cortisol secretion generates visceral fat accumulation and insulin resistance. Further investigation into the mechanisms and timing of these two pathologies as they relate to one another is needed and could be valuable in the prevention, detection, and treatment of both conditions.

Abstract
BACKGROUND Autonomous cortisol secretion was mentioned for the first time in 2016 in the European Guideline on the management of adrenal incidentalomas. OBJECTIVES Review of the state of knowledge on diagnosis, epidemiology, co-morbidities, mortality and treatment of autonomous cortisol secretion in comparison to non-hormone producing adenomas. Recommendation for clinical practice based on the current European guideline. MATERIALS UND METHODS Analysis of relevant clinical studies, discussion of basic literature and expert opinions. RESULTS AND CONCLUSIONS Autonomous cortisol secretion is a term used to describe abnormal cortisol secretion diagnosed by a pathological 1‑mg dexamethasone suppression test in patients with adrenal incidentaloma, but without clinical manifestation of overt Cushing's syndrome. It is associated with increased mortality and morbidity, especially hypertension, diabetes mellitus type II, dyslipidemia and obesity. Adrenalectomy, as the only specific therapy option, should be considered in an interdisciplinary tumour board.

Abstract
Mild hypercortisolism (mHC) is defined as an excessive cortisol secretion, without the classical manifestations of clinically overt Cushing's syndrome. This condition increases the risk of bone fragility, neuropsychological alterations, hypertension, diabetes, cardiovascular events and mortality. At variance with Cushing's syndrome, mHC is not rare, with it estimated to be present in up to 2% of individuals older than 60 years, with higher prevalence (up to 10%) in individuals with uncontrolled hypertension and/or diabetes or with unexplainable bone fragility. Measuring cortisol after a 1 mg overnight dexamethasone suppression test is the first-line test for searching for mHC, and the degree of cortisol suppression is associated with the presence of cortisol-related consequences and mortality. Among the additional tests used for diagnosing mHC in doubtful cases, the basal morning plasma adrenocorticotroph hormone, 24-h urinary free cortisol and/or late-night salivary cortisol could be measured, particularly in patients with possible cortisol-related complications, such as hypertension and diabetes. Surgery is considered as a possible therapeutic option in patients with munilateral adrenal incidentalomas and mHC since it improves diabetes and hypertension and reduces the fracture risk. In patients with mHC and bilateral adrenal adenomas, in whom surgery would lead to persistent hypocortisolism, and in patients refusing surgery or in whom surgery is not feasible, medical therapy is needed. Currently, promising though scarce data have been provided on the possible use of pituitary-directed agents, such as the multi-ligand somatostatin analog pasireotide or the dopamine agonist cabergoline for the-nowadays-rare patients with pituitary mHC. In the more frequently adrenal mHC, encouraging data are available for metyrapone, a steroidogenesis inhibitor acting mainly against the adrenal 11-βhydroxylase, while data on osilodrostat and levoketoconazole, other new steroidogenesis inhibitors, are still needed in patients with mHC. Finally, on the basis of promising data with mifepristone, a non-selective glucocorticoid receptor antagonist, in patients with mild cortisol hypersecretion, a randomized placebo-controlled study is ongoing for assessing the efficacy and safety of relacorilant, a selective glucocorticoid receptor antagonist, for patients with mild adrenal hypercortisolism and diabetes mellitus/impaired glucose tolerance and/or uncontrolled systolic hypertension.

Abstract
Adrenal tumors are commonly discovered incidentally on cross-sectional abdominal imaging performed for reasons other than adrenal mass. Incidence of adrenal tumors increased 10-fold in the past 2 decades, with most diagnosed in older adults. In any patient with a newly discovered adrenal mass, determining whether the adrenal mass is malignant and whether it is hormonally active is equally important to guide the best management. Malignancy is diagnosed in 5% to 8% of patients with adrenal tumors, with a higher risk in young patients, if history of extra-adrenal malignancy, in those with large adrenal tumors with indeterminate imaging characteristics, and in bilateral adrenal tumors. Although overt hormone excess is uncommon in adrenal incidentalomas, mild autonomous cortisol secretion can be diagnosed in up to 30% to 50% of patients. Because autonomous cortisol secretion is associated with increased cardiovascular morbidity and metabolic abnormalities, all patients with adrenal incidentalomas require work up with dexamethasone suppression test. Management of adrenal tumors varies based on etiology, associated comorbidities, and patient's preference. This article reviews the current evidence on the diagnosis and evaluation of patients with adrenal mass and focuses on management of the most common etiologies of adrenal incidentalomas.

Abstract
A growing number of patients with adrenal incidentalomas and subclinical Cushing's syndrome (SCS) led to an increasing number of different guidelines, and diagnostic and treatment recommendations. Excess cortisol secretion in patients with SCS is associated with several comorbidities, such as hypertension, dyslipidemia, type 2 diabetes mellitus, and obesity, which in the long-term increase mortality of these patients. Subtle cortisol secretion affects bone health, quality of life and causes depression, but due to the unapparent clinical features, patients with SCS are often at risk between over and under treatment. This narrative review aimed to summarize the latest recommendations on the approach to the patient with subclinical Cushing's syndrome.

Abstract
BACKGROUND Increased tissue cortisol availability has been implicated in abnormal glucose and fat metabolism in patients with obesity, metabolic syndrome, and type 2 diabetes (T2DM). Our objective was to evaluate whether blockade of glucocorticoid receptor (GR) with mifepristone ameliorates insulin resistance (IR) in overweight/obese subjects with glucose intolerance. METHODS We conducted a randomized, double-blinded, placebo-controlled, crossover study in overweight/obese individuals (n = 16, 44% female) with prediabetes or mild T2DM but not clinical hypercortisolism. Mifepristone (50 mg every 6 h) or placebo was administered for 9 days, followed by crossover to the other treatment arm after a washout period of 6 to 8weeks. At baseline and following each treatment, oral glucose tolerance test (OGTT) and frequently sampled intravenous glucose tolerance test (FSIVGTT) were performed. Insulin sensitivity was measured using FSIVGTT [primary outcome: insulin sensitivity index (SI)] and OGTT [Matsuda index (MI) and oral glucose insulin sensitivity index (OGIS)]. Hepatic and adipose insulin resistance were assessed using hepatic insulin resistance index (HIRI), and adipose tissue insulin sensitivity index (Adipo-SI) and adipo-IR, derived from the FSIVGTT. RESULTS Mifepristone administration did not alter whole-body glucose disposal indices of insulin sensitivity (SI, MI, and OGIS). GR blockade significantly improved Adipo-SI (61.7 ± 32.9 vs 42.8 ± 23.9; P = 0.002) and reduced adipo-IR (49.9 ± 45.9 vs 65.5 ± 43.8; P = 0.004), and HIRI (50.2 ± 38.7 vs 70.0 ± 44.3; P = 0.08). Mifepristone increased insulin clearance but did not affect insulin secretion or β-cell glucose sensitivity. CONCLUSION Short-term mifepristone administration improves adipose and hepatic insulin sensitivity among obese individuals with hyperglycemia without hypercortisolism.

Abstract
Adrenal incidentalomas (AI) may be associated with a mild autonomous cortisol secretion (MACS) in up to one third of cases. There is growing evidence that MACS patients actually present increased risk of cardiovascular disease and higher mortality rate, driven by increased prevalence of known cardiovascular risk factors, as well as accelerated cardiovascular remodelling. Adrenalectomy seems to have cardiometabolic beneficial effects in MACS patients but their management is still a debated topic due to the lack of high-quality studies. Several studies suggested that so called "non-functioning" AI may be actually "functioning" with an associated increased cardiovascular risk. Although the individual cortisol sensitivity and peripheral activation have been recently suggested to play a role in influencing the cardiovascular risk even in apparently eucortisolemic patients, to date the degree of cortisol secretion, as mirrored by the cortisol levels after dexamethasone suppression test remains the best predictor of an increased cardiovascular risk in AI patients. However, whether or not the currently used cut-off set at 50 nmol/L for cortisol levels after dexamethasone suppression could be considered completely reliable in ruling out hypercortisolism remains unclear.

Abstract
OBJECTIVE Autonomous cortisol secretion (ACS) is the most common endocrine abnormality in the evaluation of adrenal incidentalomas. The categorization of ACS is derived from a 1 mg dexamethasone suppression test (DST). Impaired DST is associated with several metabolic derangements. In this study we analyzed the association between post-DST cortisol level, analyzed as a continuous parameter, and indices of glycemic metabolism. METHODS We prospectively collected data of 1,976 patients evaluated for adrenal incidentalomas in a large tertiary medical center between December 1, 2017, and August 31, 2019. Seventy-three patients completed the evaluation process. Post-DST cortisol levels were analyzed for correlation with various metabolic parameters, including fasting plasma glucose (FPG) and hemoglobin A1c (HbA1c) among the general cohort and for subgroups stratified by the number of metabolic syndrome (MS) criteria. RESULTS Post-DST cortisol demonstrated a linear association with FPG and HbA1c across its entire cortisol range (R = 0.51 and 0.41, respectively; P≤.01). The association between post-DST cortisol and FPG was strengthened with an increased number of metabolic syndrome criteria. Patients with 4 MS criteria show a stronger association (R = 0.92) compared to patients with only a single criterion (R = 0.509). Furthermore, mean post-DST cortisol levels increased as the number of MS criteria accumulated. CONCLUSION Post-DST cortisol should be viewed as a continuous parameter in risk stratification algorithms for the development of MS and particularly dysglycemia.

Abstract
BACKGROUND While surgery is the first-line treatment for patients with endogenous hypercortisolism (Cushing syndrome [CS]), mifepristone has been shown to be a beneficial medical treatment option, as demonstrated in the SEISMIC (Study of the Efficacy and Safety of Mifepristone in the Treatment of Endogenous Cushing Syndrome) trial. Mifepristone is a competitive glucocorticoid receptor antagonist and progesterone receptor antagonist that is associated with several treatment effects and adverse events that clinicians need to be aware of when considering its use. The objective of this review was to provide updated clinical management recommendations for patients with CS treated with mifepristone. METHODS A panel of endocrinologists from the US with extensive experience in treating patients with CS, including with mifepristone, convened as part of a clinical advisory board to develop a consensus on the practical, real-world clinical management of patients on mifepristone. RESULTS Comprehensive considerations and recommendations are provided for managing mifepristone-associated effects, including symptoms of cortisol withdrawal, hypokalemia, and change in thyroid function; effects related to its antiprogesterone activity; and rash. Additional management strategies to address concomitant medications and special clinical situations, such as surgery and use in specific populations, are also provided. CONCLUSION Safe and effective use of mifepristone requires clinical judgment and close patient monitoring to ensure optimal clinical outcomes. These consensus recommendations provide useful, practical guidance to clinicians using mifepristone.

Abstract
The European society of endocrinology, in association with the European network for the study of adrenal tumors, published recommendations for the diagnosis and treatment of adrenal incidentalomas in 2016. A thorough and critical analysis of the literature was performed to establish evidence-based recommendations and expert suggestions with the aim of avoiding 'over-diagnosis' and 'over-treatment' and to reduce unnecessary investigations, surgery and follow-up. The purpose of this review is to reconsider several recommendations that are open to debate, such as imaging of adrenal incidentalomas, diagnosis of pheochromocytoma, diagnosis and treatment of autonomous cortisol-secreting tumors, investigations of bilateral AI and follow-up of non-operated AIs, based on studies published after the release of the recommendations.

Abstract
In the vast majority of cases adrenal incidentalomas (AI) are benign adrenocortical adenomas. They are present in up to 10% of the population over 70 years, with incidence increasing with age. Mild cortisol excess (MCE) in the context of AI is defined as autonomous cortisol secretion (ACS) in the absence of the classical clinical features of Cushing's syndrome. MCE has been reported in up to at least one third of patients with AI. Numerous studies have shown that MCE in AI is associated with increased cardiovascular events and mortality, likely to be consequent upon both hemodynamic changes and inflammatory pathways, and a worse metabolic phenotype characterized by: pancreatic β-cell dysfunction, insulin resistance, visceral obesity and dyslipidemia. There is currently no level 3 evidence from large intervention randomized controlled trials to guide management of MCE in AI, and there is a lack of predictive tools to allow stratification to intervention of only those patients who would benefit in terms of improved metabolic and cardiovascular end-points. Here, we describe the mal-effects of cortisol on cardiovascular and metabolic tissues and discuss management strategies based on current largely observational data.

Abstract
Incidentally discovered adrenal tumors are reported in ~ 5% of adults undergoing cross-sectional imaging. Mild autonomous cortisol secretion (MACS) from the adrenal mass is demonstrated in 5-48% of patients with adrenal tumors. The diagnosis of MACS represents a challenge due to limitations of the currently used diagnostic tests, differences in the definitions of the clinically relevant MACS, and heterogeneity in an individual's susceptibility to abnormal cortisol secretion from the adrenal mass. Patients with MACS present with increased risk of cardiovascular risk factors, cardiovascular events, metabolic bone disease, and mortality. Adrenalectomy improves or reverses MACS-associated comorbidities in selected patients. The current review will address diagnostic and management challenges in the care of patients with MACS, discuss data on emerging biomarkers, and suggest future directions in the field of MACS.

Abstract
Objective: Adrenal incidentalomas are increasingly detected with the widespread use of thoracic and abdominal imaging. The most common secretory syndrome in adrenal nodules is autonomous cortisol secretion (ACS). Recent data show that even mild cortisol excess is associated with adverse outcomes. The glucocorticoid receptor antagonist mifepristone has been used in patients with overt Cushing syndrome and hyperglycemia. The purpose of our study was to determine the effect of mifepristone on metabolic parameters in patients with ACS and concomitant prediabetes or diabetes. Methods: Eight patients with either unilateral or bilateral adrenal nodules with ACS were included in the study. Fasting laboratory tests including glucose and insulin levels to calculate homeostatic model assessment for insulin resistance (HOMA-IR) were performed at baseline and again after either 3 months (3 patients) or 6 months (5 patients) on mifepristone 300 mg daily treatment. Patients also completed several validated surveys on mood and quality of life at baseline and follow-up. Results: There were significant reductions in fasting glucose measurements and insulin resistance as measured by HOMA-IR in the 6 of 8 study patients in whom these measurements were available (P = .03). Conclusion: This pilot study demonstrates that mifepristone treatment of ACS is associated with a significant decrease in fasting glucose and insulin resistance as measured by HOMA-IR scores. Mifepristone treatment of ACS may be considered as a medical option for patients with ACS due to adrenal adenomas with concomitant abnormal glucose parameters in whom surgical removal is not being considered. Abbreviations: ACS = autonomous cortisol secretion; ACTH = adrenocorticotropic hormone; AI = adrenal incidentaloma; DHEAS = dehydroepiandrosterone sulfate; GR = glucocorticoid receptor; HbA1c = hemoglobin A1c; HOMA-IR = homeostatic model assessment for insulin resistance; ODT = overnight dexamethasone suppression test; QoL = quality of life; STAI = state trait anxiety inventory; TSH = thyroid stimulating hormone; UFC = urinary free cortisol.

Abstract
Cushing's syndrome is associated with increased morbidity and mortality. Cardiovascular events, sepsis, and thromboembolism are the leading causes of mortality. Patient's with Cushing's due to a pituitary adenoma and those with Cushing's due to benign adrenal adenoma have relatively good survival outcomes often mirroring that of the general population. Persistent or recurrent disease is associated with high mortality risk. Ectopic Cushing's syndrome and Cushing's due to adrenocortical carcinoma confer the highest mortality risk among Cushing's etiologies. Prompt diagnosis and treatment, and specific monitoring for and treatment of associated comorbidities are essential to decrease the burden of mortality from Cushing's.

Abstract
Adrenal incidentaloma is a frequent clinical finding. Once an adrenal mass is detected, is mandatory to determine whether the lesion is malignant or benign and whether it is hormonally active or non-functioning, to estabilish an adequate treatement or follow-up. The European Society of Endocrinology and ENSAT Guideline recently provided the best recommendation based on the available literature. However, due to the retrospective design of the majority of the studies, the small number of patients included and the inadequate follow-up, some issues are still unresolved. In particular, there is a general consensus about the need of adrenalectomy in the presence of unilateral adrenal mass and clinically relevant hormone excess or radiological findings suspected for malignancy. On the other side, how to manage adrenal masses with indeterminate characteristics or subtle cortisol secretion, and how long the radiological and functional follow-up of benign adrenal mass should last in non-operated patients, are still open questions. Therefore, high-quality research for establish the adequate management of these patients and randomized clinical trials are needed to avoid unnecessary investigations and invasive procedures and ensure a clinically effective work-up.

Abstract
"Subclinical hypercortisolism" (SH) refers to a condition associated with a mild chronic increase in cortisol secretion. By definition, patients with SH do not exhibit specific symptoms of overt Cushing's syndrome (such as purple striae, easy bruising, proximal muscle weakness), SH has been preferred to "subclinical Cushing's syndrome", a semantic ambiguity since Cushing's syndrome is, by definition, a set of symptoms; and to the term "preclinical Cushing syndrome" because the progression toward overt clinical hypercortisolism is very rare. However, SH still is misnomer as a number of studies suggest that this condition may induce long-term non-specific adverse conditions related to the mild cortisol excess (i.e. diabetes, hypertension, obesity, and osteoporosis). Various attempts have been made to define SH that remains a matter of controversies and uncertainties.

Abstract
Patients with adrenal incidentaloma (AI) and subclinical hypercortisolism (SH) show a high prevalence of cardiovascular risk factors and an increased prevalence and incidence of cardiovascular events. Furthermore, some recent data suggest that in these patients, the cardiovascular mortality is also increased. Unfortunately, to date, the diagnosis of SH is still a matter of debate, and, therefore, it is still not possible to address the treatment of choice (i.e. surgical or conservative approach) in many AI patients. Overall, the available data show that in AI patients with established SH the surgical removal of the adrenal mass causing SH can lead to the improvement of hypertension and diabetes, but in many patients with possible SH the effect of surgery is still largely unknown. Finally, no data are available on the effect of the recovery from SH on the cardiovascular events. Therefore, randomized studies are needed to investigate the possibility of predicting the usefulness of surgery by using the available indexes of cortisol secretion in the individual AI patient. Finally, the development of safe and well-tolerated drugs aimed to control cortisol secretion will be among the goals of the future research.

Abstract
An impaired glucose metabolism, which often leads to the onset of diabetes mellitus (DM), is a common complication of chronic exposure to exogenous and endogenous glucocorticoid (GC) excess and plays an important part in contributing to morbidity and mortality in patients with Cushing syndrome (CS). This article reviews the pathogenesis, epidemiology, diagnosis, and management of changes in glucose metabolism associated with hypercortisolism, addressing both the pathophysiological aspects and the clinical and therapeutic implications. Chronic hypercortisolism may have pleiotropic effects on all major peripheral tissues governing glucose homeostasis. Adding further complexity, both genomic and nongenomic mechanisms are directly induced by GCs in a context-specific and cell-/organ-dependent manner. In this paper, the discussion focuses on established and potential pathologic molecular mechanisms that are induced by chronically excessive circulating levels of GCs and affect glucose homeostasis in various tissues. The management of patients with CS and DM includes treating their hyperglycemia and correcting their GC excess. The effects on glycemic control of various medical therapies for CS are reviewed in this paper. The association between DM and subclinical CS and the role of screening for CS in diabetic patients are also discussed.

Abstract
BACKGROUND Glucocorticoid replacement is commonly required to treat secondary adrenal insufficiency after surgical resection of unilateral cortisol-secreting adrenocortical adenomas. Here, we describe a patient with unilateral cortisol-secreting adenomas in which the preoperative use of mifepristone therapy was associated with recovery of the hypothalamic-pituitary-adrenal (HPA) axis, eliminating the need for postoperative glucocorticoid replacement. CASE PRESENTATION A 66-year-old Caucasian man with type 2 diabetes mellitus, hyperlipidemia, hypertension, and obesity was hospitalized for Fournier's gangrene and methicillin-resistant Staphylococcus aureus sepsis. Abdominal computed tomography scan revealed three left adrenal adenomas measuring 1.4, 2.1, and 1.2 cm and an atrophic right adrenal gland. Twenty-four-hour urinary free cortisol level was elevated (237 µg/24 hours, reference range 0-50 µg/24 hours). Hormonal evaluation after resolution of the infection showed an abnormal 8 mg overnight dexamethasone suppression test (cortisol postdexamethasone 14.5 µg/dL), suppressed adrenocorticotropic hormone (ACTH; <5 pg/mL, reference range 7.2-63.3 pg/mL), and low-normal dehydroepiandrosterone sulfate (50.5 µg/dL, male reference range 30.9-295.6 µg/dL). Because of his poor medical condition and uncontrolled diabetes, his Cushing's syndrome was treated with medical therapy before surgery. Mifepristone therapy was started and, within five months, his diabetes was controlled and insulin discontinued. The previously suppressed ACTH increased to above normal range accompanied by an increase in dehydroepiandrosterone sulfate levels, indicating recovery of the HPA axis and atrophic contralateral adrenal gland. The patient received one precautionary intraoperative dose of hydrocortisone and none thereafter. Two days postoperatively, ACTH (843 pg/mL) and cortisol levels (44.8 µg/dL) were significantly elevated, reflecting an appropriate HPA axis response to the stress of surgery, and two weeks postoperatively, ACTH was within normal range and a repeat dexamethasone suppression test was normal. Six months postoperatively, ACTH was within normal limits and cortisol was approaching normal. The patient has exhibited no postoperative signs or symptoms of adrenal insufficiency in 12 months. CONCLUSION Preoperative mifepristone therapy was associated with apparent recovery of the HPA axis prior to unilateral adrenalectomy in a patient with unilateral adrenal adenomas. Postoperatively, the patient experienced no signs or symptoms of adrenal insufficiency and no glucocorticoid replacement was required.

Abstract
OBJECTIVE To examine the relationship between dose, clinical response (based on independent evaluation of metabolic, physical, neurologic, and social assessments), and safety of mifepristone treatment in patients with endogenous Cushing syndrome (CS). METHODS This post hoc analysis included 40 clinical responders and 50 participants who received a dose of mifepristone (safety population) in the 24-week phase 3 SEISMIC (Study of the Efficacy and Safety of Mifepristone in the Treatment of Endogenous Cushing Syndrome) trial. The dose of mifepristone at the initial clinical response was analyzed, and the rate of serious adverse events (SAEs) and AEs reported in ≥20% of patients were compared to average mifepristone doses over time. RESULTS Among the clinical responders, 85% and 35% had their initial clinical responses at mifepristone doses ≥600 and ≥900 mg/day, respectively. The SAE rate did not increase with a higher dose over time. The AE rates for fatigue, headache, nausea, and peripheral edema declined significantly at weeks 16 to 24 (all P<.05 vs. weeks 1-2) as the study progressed and mifepristone doses were increased. Other AEs such as hypokalemia, vomiting, and decreased appetite did not significantly increase from weeks 1 to 2 as mifepristone doses were increased. CONCLUSIONS The majority of clinical responders in the SEISMIC trial received mifepristone doses ≥600 mg/day suggesting that higher doses were required to achieve optimal clinical benefit in patients with endogenous CS. Notably, mifepristone dose escalations did not result in any significant or concordant increase in the rates of SAEs and common AEs.

Abstract
Adrenal incidentalomas have become detected more often as the use of abdominal imaging has increased. Up to one-third of these may be secreting low levels of cortisol, known as mild hypercortisolism or subclinical Cushing syndrome. These low levels of cortisol have been found to be associated with an increased in the metabolic syndrome, osteoporosis, cardiovascular events, and mortality. This article discusses in detail the epidemiology, diagnosis, clinical associations, and treatment options of mild hypercortisolism.

Abstract
PURPOSE OF REVIEW The article aims to update the reader on current developments in the area of adrenal incidentaloma complicated by subclinical hypercortisolism. We will discuss different diagnostic strategies and complications associated with this disease, and address the conflicting opinions related to the treatment of these patients. RECENT FINDINGS Depending on diagnostic criteria used, between 30 and 50% of patients with adrenocortical incidentaloma have biochemical hypercortisolism, but lack classical external features of Cushing's syndrome. The challenge facing the clinician is that in the sixth and seventh decade of life hypertension, diabetes, osteoporosis and obesity are common and establishing whether these are directly related to the low-grade excess cortisol secretion in a given individual is not straightforward. Nevertheless, this subclinical hypercortisolism has been found to be associated with multiple cardiovascular risk factors, an increased predisposition to cardiovascular events and a higher mortality rate. The dilemma is that it is not established whether surgical excision of the adrenal adenoma in a given individual will improve these complications, and data demonstrate that surgical studies are conflicting. SUMMARY Subclinical hypercortisolism is associated with multiple complications and definite guidelines for diagnosis are necessary. Prospective, randomized controlled studies are needed to ascertain whether medical or surgical interventions are justified, and in which patients.

Abstract
In normal pregnancy, cortisol increases; however, further pathological increases in cortisol are associated with maternal and fetal morbidities. These experiments were designed to test the hypothesis that increased maternal cortisol would increase maternal glucose concentrations, suppress fetal growth, and impair neonatal glucose homeostasis. Ewes were infused with cortisol (1 mg·kg(-1)·day(-1)) from day 115 of gestation to term; maternal glucose, insulin, ovine placental lactogen, estrone, progesterone, nonesterified free fatty acids (NEFA), β-hydroxybutyrate (BHB), and electrolytes were measured. Infusion of cortisol increased maternal glucose concentration and slowed the glucose disappearance after injection of glucose; maternal infusion of cortisol also increased the incidence of fetal death at or near parturition. The design of the study was altered to terminate the study prior to delivery, and post hoc analysis of the data was performed to test the hypothesis that maternal metabolic factors predict the fetal outcome. In cortisol-infused ewes that had stillborn lambs, plasma insulin was increased relative to control ewes or cortisol-infused ewes with live lambs. Maternal cortisol infusion did not alter maternal food intake or plasma NEFA, BHB, estrone, progesterone or placental lactogen concentrations, and it did not alter fetal body weight, ponderal index, or fetal organ weights. Our study suggests that the adverse effect of elevated maternal cortisol on pregnancy outcome may be related to the effects of cortisol on maternal glucose homeostasis, and that chronic maternal stress or adrenal hypersecretion of cortisol may create fetal pathophysiology paralleling some aspects of maternal gestational diabetes.

Abstract
The blockade of glucocorticoid (GC) action through antagonism of the glucocorticoid receptor II (GRII) has been used to minimize the undesirable effects of chronically elevated GC levels. Mifepristone (RU486) is known to competitively block GRII action, but not exclusively, as it antagonizes the progesterone receptor. A number of new selective GRII antagonists have been developed, but limited testing has been completed in animal models of overt type 2 diabetes mellitus. Therefore, two selective GRII antagonists (C113176 and C108297) were tested to determine their effects in our model of GC-induced rapid-onset diabetes (ROD). Male Sprague-Dawley rats (∼ six weeks of age) were placed on a high-fat diet (60%), surgically implanted with pellets containing corticosterone (CORT) or wax (control) and divided into five treatment groups. Each group was treated with either a GRII antagonist or vehicle for 14 days after surgery: CORT pellets (400 mg/rat) + antagonists (80 mg/kg/day); CORT pellets + drug vehicle; and wax pellets (control) + drug vehicle. After 10 days of CORT treatment, body mass gain was increased with RU486 (by ∼20% from baseline) and maintained with C113176 administration, whereas rats given C108297 had similar body mass loss (∼15%) to ROD animals. Fasting glycemia was elevated in the ROD animals (>20 mM), normalized completely in animals treated with RU486 (6.2±0.1 mM, p<0.05) and improved in animals treated with C108297 and C113176 (14.0±1.6 and 8.8±1.6 mM, p<0.05 respectively). Glucose intolerance was normalized with RU486 treatment, whereas acute insulin response was improved with RU486 and C113176 treatment. Also, peripheral insulin resistance was attenuated with C113176 treatment along with improved levels of β-cell function while C108297 antagonism only provided modest improvements. In summary, C113176 is an effective agent that minimized some GC-induced detrimental metabolic effects and may provide an alternative to the effective, but non-selective, GRII antagonist RU486.
