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.

Predicting postoperative hypocortisolism in patients with non-aldosterone-producing adrenocortical adenoma: a retrospective single-centre study. J Endocrinol Invest 2024; 47:1751-1762. [PMID: 38386266 PMCID: PMC11196308 DOI: 10.1007/s40618-023-02283-1] [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: 08/27/2023] [Accepted: 12/14/2023] [Indexed: 02/23/2024]
Abstract
BACKGROUND Limited information exists on postoperative hypocortisolism and hypothalamus-pituitary-adrenal axis recovery in patients with adrenal incidentaloma following unilateral adrenalectomy. We evaluated frequency of postoperative hypocortisolism and predictors for recovery in non-aldosterone-producing adrenocortical adenoma patients after unilateral adrenalectomy. METHODS A retrospective analysis of 32 adrenal incidentaloma patients originally included in the ITACA trial (NCT04127552) with confirmed non-aldosterone-producing adrenocortical adenoma undergoing unilateral adrenalectomy from September 2019 to April 2023 was conducted. Preoperative assessments included adrenal MRI, anthropometrics, evaluation of comorbidities, adrenal function assessed via ACTH, urinary free cortisol, and 1 mg dexamethasone suppression test. ACTH and serum cortisol or Short Synacthen test were performed within 6 days, 6 weeks, 6 months, and a year after surgery. RESULTS Six days postoperative, 18.8% of patients had normal adrenal function. Among those with postoperative hypocortisolism, 53.8% recovered by 6 weeks. Patients with earlier adrenal recovery (6 weeks) had lower preoperative 1 mg dexamethasone suppression test (median 1 mg dexamethasone suppression test 76.2 [61.8-111.0] nmol/L vs 260.0 [113.0-288.5] nmol/L, p < 0.001). Univariate analysis showed preoperative 1 mg dexamethasone suppression test negatively related with baseline ACTH levels (r = - 0.376; p = 0.041) and negatively associated with the 6-week baseline (r = - 0.395, p = 0.034) and 30-min cortisol levels during Short Synacthen test (r = - 0.534, p = 0.023). Logistic regression analysis demonstrated preoperative 1 mg dexamethasone suppression test as the only biochemical predictor for 6-week adrenal recovery: ROC curve identified a 1 mg dexamethasone suppression test threshold of 131 nmol/L predicting 6-week recovery with 89.5% sensitivity and 72.7% specificity (AUC 0.87; 95% CI 66.9-98.7, p < 0.001). Other preoperative assessments (tumor size, ACTH levels and anthropometrics) were not associated with postoperative hypothalamus-pituitary-adrenal axis function, but the presence of diabetes was associated with a lower probability of recovery (OR = 24.55, p = 0.036). ACTH levels increased postoperatively in all patients but did not predict hypothalamus-pituitary-adrenal axis recovery. CONCLUSIONS The preoperative 1 mg dexamethasone suppression test cortisol value and presence of diabetes are the only relevant predictor of hypothalamus-pituitary-adrenal axis recovery in patients with non-aldosterone- producing adrenocortical adenoma undergoing surgery, regardless other clinical and biochemical variables. Notably, pre- and postoperative ACTH levels did not predict hypothalamus-pituitary-adrenal axis recovery. These findings point towards the potential for saving resources by optimizing their allocation during follow-up assessments for patients with non-aldosterone-producing adrenocortical adenoma undergoing unilateral adrenalectomy.

Laparoscopic adrenalectomy for adrenal tumors with endocrine activity: Perioperative management pathways for reduced complications and improved outcomes. Int J Urol 2023; 30:818-826.

Abstract
The major adrenal tumors with endocrine activity are primary aldosteronism, Cushing's syndrome/mild autonomous cortisol secretion, and pheochromocytoma/paraganglioma. Excessive aldosterone secretion in primary aldosteronism causes cardiovascular, renal, and other organ damage in addition to hypertension and hypokalemia. Cortisol hypersecretion in Cushing's syndrome/mild autonomous cortisol secretion causes obesity, hypertension, impaired glucose tolerance, and cardiometabolic syndrome. Massive secretion of catecholamines in pheochromocytoma/paraganglioma causes hypertension and cerebrocardiovascular disease due to rapid blood pressure fluctuation. Moreover, pheochromocytoma multi-system crisis is a feared and possibly fatal presentation of pheochromocytoma/paraganglioma. Thus, adrenal tumors with endocrine activity are considered an indication for adrenalectomy, and perioperative management is very important. They have a risk of perioperative complications, either due to direct hemodynamic effects of the hormone hypersecretion or due to hormone-related comorbidities. In the last decades, deliberate preoperative evaluation and advanced perioperative management have significantly reduced complications and improved outcomes. Furthermore, improvements in anesthesia and surgical techniques with the feasibility of laparoscopic adrenalectomy have contributed to reduced morbidity and mortality. However, there are still several challenges to be considered in the perioperative care of these patients. There are very few data available prospectively to guide clinical management, due to the rarity of adrenal tumors with endocrine activity. Therefore, most guidelines are based on retrospective data analyses or small case series. In this review, the latest knowledge is summarized, and practical pathways to reduce perioperative complications and improve outcomes in adrenal tumors with endocrine activity are presented.

Abstract
PURPOSE Adrenal incidentalomas (AIs) are incidentally discovered adrenal masses, during an imaging study undertaken for other reasons than the suspicion of adrenal disease. Their management is not a minor concern for patients and health-care related costs, since their increasing prevalence in the aging population. The exclusion of malignancy is the first question to attempt, then a careful evaluation of adrenal hormones is suggested. Surgery should be considered in case of overt secretion (primary aldosteronism, adrenal Cushing's Syndrome or pheochromocytoma), however the management of subclinical secretion is still a matter of debate. METHODS The aim of the present narrative review is to offer a practical guidance regarding the management of AI, by providing evidence-based answers to frequently asked questions. CONCLUSION The clinical experience is of utmost importance: a personalized diagnostic-therapeutic approach, based upon multidisciplinary discussion, is suggested.

Abstract
PURPOSE Primary aldosteronism (PA) is the most frequent type of endocrine hypertension. In our previous studies, we introduced two modified diagnostic tests for PA, the post-dexamethasone saline infusion test (DSIT) and the overnight dexamethasone, captopril, and valsartan test (DCVT). In this study, we aimed to validate both tests in respect to the biochemical and clinical response of a cohort of hypertensive patients in pre- and post-surgical setting. METHODS We retrospectively studied 41 hypertensive patients (16 males), with a median (IQR, range) age of 50 (16, 35-74) years and positive histology for adrenal adenoma. Preoperatively, all patients had a single adenoma on CT and a diagnosis of PA with either DSIT or DCVT. The defined daily dose (DDD) of hypertensive drugs was assessed pre- and postoperatively. DSIT or DCVT and basal ARR were reassessed postoperatively. RESULTS Two of the 41 patients failed to suppress aldosterone post-surgery, leading to a post-adrenalectomy biochemical cure rate of 95%, while blood pressure was improved in 36 patients, leading to a clinical cure rate of 88% as assessed by the DDD methodology. CONCLUSIONS The present study was a proof-of-concept process to validate two modified diagnostic tests for PA in clinical practice. These tests, used to diagnose a group of patients with PA, successfully assessed their biochemical cure post-adrenalectomy at rates similar to those reported in the literature.

Abstract
An adrenal incidentaloma is now established as a common endocrine diagnosis that requires a multidisciplinary approach for effective management. The majority of patients can be reassured and discharged, but a personalized approach based upon image analysis, endocrine workup, and clinical symptoms and signs are required in every case. Adrenocortical carcinoma remains a real concern but is restricted to <2% of all cases. Functional adrenal incidentaloma lesions are commoner (but still probably <10% of total) and the greatest challenge remains the diagnosis and optimum management of autonomous cortisol secretion. Modern-day surgery has improved outcomes and novel radiological and urinary biomarkers will improve early detection and patient stratification in future years to come.

Abstract
OBJECTIVE This study aimed to provide rational guidelines for patients with subclinical Cushing syndrome (SCS), who are undergoing laparoscopic adrenalectomy, in order to avoid the risk of overtreatment. METHODS A total of 59 patients diagnosed with SCS caused by unilateral adrenal adenoma, who underwent laparoscopic adrenalectomy from 2010 to 2017, were included into the study. These patients did not receive prophylactic steroid treatment. After discharge, patients with adrenal insufficiency (AI) were treated with glucocorticoid. Then, cortisol levels were reevaluated at three months after surgery by morning serum cortisol. RESULTS No severe perioperative complications occurred. After unilateral laparoscopic adrenalectomy, no patient developed AI and was readmitted. In the first week after surgery, 10 patients (16.9%) received steroid therapy at the clinic because of mild symptoms of AI. The probability of developing AI was greater in patients with 1-mg dexamethasone midnight suppression test (1 mg-DST) >5 μg/dL than patients with mg-DST ranging within 1.8 to 5.0 μg/dL (P=0.042). The initial dose of hydrocortisone was 20.00±6.67 mg/d (range, 10 to 30), and the duration of treatment was 6.90±3.51 weeks (range, 3 to 12 wk). At three months after surgery, morning cortisol was >5 μg/dL in all patients. CONCLUSIONS After laparoscopic adrenalectomy, the probability of AI is small in patients with adrenal SCS, and the symptoms of AI were mild. Meanwhile, the HPA axis rapidly recovered. Therefore, prophylactic steroid treatment is not mandatory. Given that AI is more frequent in patients with higher cut-offs of 1 mg-DST, a more precise definition of SCS is necessary to better manage these patients.

Abstract
BACKGROUND A growing body of evidence suggests that nonfunctioning and subclinical cortisol secreting adrenal incidentalomas (AIs) are associated with several components of metabolic syndrome resulting in increased cardiometabolic risk. The long-term metabolic outcome of these AIs is largely unknown and their most appropriate management remains controversial. OBJECTIVES To undertake a systematic review of the prevalence of cardiometabolic abnormalities in nonfunctioning and subclinical cortisol secreting AIs and long-term outcome of conservative treatment and adrenalectomy. METHODS MEDLINE, Cochrane Controlled Trials Register, and EMBASE were searched for relevant studies and systematic review was performed. National Institutes of Health (NIH) quality assessment tool for observational cohort and cross-sectional studies was used to assess the risk of bias in the studies. RESULTS Of the 65 studies screened, 18 (10 retrospective, 5 prospective, 2 cross-sectional studies, and 1 randomized controlled trial) were included in the systematic review. Prevalence of hypertension (HTN), impaired glucose metabolism, dyslipidaemia, and raised body mass index (BMI) was higher in subclinical cortisol secreting AIs as compared with nonfunctioning AIs. Surgical intervention had a beneficial effect on blood pressure, glucometabolic control, and obesity in patients with subclinical Cushing's syndrome. The results for lipid metabolism were equivocal. There was no significant improvement in cardiometabolic risk factors after adrenalectomy in nonfunctioning AIs. The quality of evidence was found to be low to moderate. CONCLUSIONS The systematic review demonstrated increased prevalence of components of metabolic syndrome in patients with subclinical cortisol secreting and nonfunctioning AIs. A beneficial role of adrenalectomy on HTN, glucometabolic control, and BMI was observed in patients with subclinical cortisol secreting AIs.

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 Adrenal adenomas are benign tumors often discovered incidentally, and >70% are hormonally inactive. The remaining subset may produce excess aldosterone, cortisol, or catecholamine. Perioperative outcomes after adrenalectomy for such "hormonally active" tumors remain unclear. This study examines in-hospital outcomes after unilateral adrenalectomy for hormonally active tumors. METHODS A retrospective review was performed using the Nationwide Inpatient Sample (2006-2011) to identify patients undergoing unilateral adrenalectomy for hormonally active or inactive tumors. Malignant adrenal tumors were excluded. Demographics, comorbidities, and postoperative complications were evaluated by univariate analysis, using two-tailed Chi-square and t-tests and multivariate logistic regression. RESULTS Of 27,312 patients who underwent adrenalectomy, 78% (n = 21,279) had hormonally inactive and 22% (n = 6033) had hormonally active adrenal tumors. Among the latter, 65% (n = 4000) had primary hyperaldosteronism (Conn's syndrome), 33% (n = 1996) had hypercortisolism (Cushing's syndrome), and 1.4% (n = 85) had pheochromocytoma. Patients with pheochromocytoma had higher rate of comorbidities including congestive heart failure, chronic lung disease, and malignant hypertension compared with remaining hormonally active tumors (12% versus 4%, 18% versus 11%, 6% versus 2%; P < 0.01). For patients with pheochromocytoma versus other hormonally active tumors, mean length of stay was 5 versus 3 d and total in-hospital cost was $50,000 versus $41,000 (P < 0.01). On multivariate analysis, pheochromocytoma had an independently higher risk for intraoperative blood transfusion (4.2, 95% confidence interval [CI] 2.4-7.2), postoperative cardiac (7.6, 95% CI 2.8-20.2), and respiratory (1.9, 95% CI 1.0-3.3) complications. CONCLUSIONS Patients with pheochromocytoma have high rates of preoperative comorbidities, postoperative cardiopulmonary complications, and longer and more costly hospitalizations. Such high-risk patients should undergo appropriate preoperative medical optimization in preparation for adrenalectomy.

Abstract
OBJECTIVE Beneficial effects of adrenalectomy on cardiovascular risk factors in patients with subclinical Cushing's syndrome (SCS) are uncertain. We sought to conduct a systematic review and meta-analysis with the following objectives: (i) determine the effect of adrenalectomy compared with conservative management on cardiovascular risk factors in patients with SCS and (ii) compare the effect of adrenalectomy on cardiovascular risk factors in patients with SCS vs those with a nonfunctioning (NF) adrenal tumor. METHODS MEDLINE In-Process & Other Non-Indexed Citations, MEDLINE, EMBASE and Cochrane Central Register of Controlled Trial were searched on 17 November 2015. Reviewers extracted data and assessed methodological quality in duplicate. RESULTS We included 26 studies reporting on 584 patients with SCS and 457 patients with NF adrenal tumors. Studies used different definitions of SCS. Patients with SCS undergoing adrenalectomy demonstrated an overall improvement in cardiovascular risk factors (61% for hypertension, 52% for diabetes mellitus, 45% for obesity and 24% for dyslipidemia). When compared with conservative management, patients with SCS undergoing adrenalectomy experienced improvement in hypertension (RR 11, 95% CI: 4.3-27.8) and diabetes mellitus (RR 3.9, 95% CI: 1.5-9.9), but not dyslipidemia (RR 2.6, 95% CI: 0.97-7.2) or obesity (RR 3.4, 95% CI: 0.95-12). Patients with NF adrenal tumors experienced improvement in hypertension (21/54 patients); however, insufficient data exist for comparison to patients with SCS. CONCLUSIONS Available low-to-moderate-quality evidence from heterogeneous studies suggests a beneficial effect of adrenalectomy on cardiovascular risk factors in patients with SCS overall and compared with conservative management.

Abstract
BACKGROUND We compared operative and metabolic outcomes in patients with subclinical Cushing syndrome and Cushing syndrome caused by unilateral adrenal lesion, aiming to clarify the role of glucocorticoid replacement treatment in patients with subclinical Cushing syndrome after adrenalectomy. METHODS The medical records of all the patients who underwent unilateral adrenalectomy for subclinical Cushing syndrome or Cushing syndrome were reviewed. Diagnostic criteria for subclinical Cushing syndrome were a pathologic dexamethasone suppression test plus 2 additional criteria. RESULTS Twenty-nine patients with subclinical Cushing syndrome and 50 with Cushing syndrome were identified. No significant difference was found between patients with subclinical Cushing syndrome and Cushing syndrome regarding lesion size, operative time, and hospital stay. Two patients out of 29 with subclinical Cushing syndrome and 3 out of 50 patients with Cushing syndrome experienced Clavien-Dindo grade II complications (P = .87). All the patients required postoperative glucocorticoid replacement that was discontinued within 6 months in 28 of the 29 patients with subclinical Cushing syndrome and in 3 out of 50 Cushing syndrome patients (P < .005). At long-term follow-up, adrenalectomy significantly improved hypertension and diabetes in affected patients, with no differences between subclinical Cushing syndrome and Cushing syndrome. Hypercortisolism was resolved in all the cases. CONCLUSION Operative and metabolic outcomes of adrenalectomy are similar in subclinical Cushing syndrome and Cushing syndrome. Postoperative glucocorticoid replacement treatment is advisable in all patients with subclinical Cushing syndrome. Prolonged adrenal insufficiency is more frequent in Cushing syndrome patients.

Abstract
The pathogenetic mechanisms underlying the onset of adrenocortical tumors (ACTs) are still largely unknown. Recently, more attention has been paid to the role of insulin and insulin-like growth factor (IGF) system on general tumor development and progression. Increased levels of insulin, IGF-1 and IGF-2 are associated with tumor cell growth and increased risk of cancer promotion and progression in patients with type 2 diabetes. Insulin resistance and compensatory hyperinsulinemia may play a role in adrenal tumor growth through the activation of insulin and IGF-1 receptors. Interestingly, apparently non-functioning ACTs are often associated with a high prevalence of insulin resistance and metabolic syndrome. However, it is unclear if ACT develops from a primary insulin resistance and compensatory hyperinsulinemia or if insulin resistance is only secondary to the slight cortisol hypersecretion by ACT. The aim of this review is to summarize the current evidence regarding the relationship between hyperinsulinemia and adrenocortical tumors.

Abstract
Subclinical hypercortisolism (SH), defined as alterations of the hypothalamus-pituitary-adrenal axis in the absence of clinical signs or symptoms related to cortisol secretion, is a common finding in patients with adrenal incidentalomas. The clinical correlates of this pathological condition have become clearer over the last few years. The aim of this review is to summarize the co-morbidities and the clinical outcomes of patients with SH. According to the analysis of the results of the studies published within the last 15 years, hypertension and type 2 diabetes are a common finding in patients with SH, occurring roughly in 2/3 and 1/3 of the patients respectively. Moreover, several additional cardiovascular and metabolic complications, like endothelial damage, increased visceral fat accumulation and impaired lipid metabolism have been shown to increase the cardiovascular risk of those patients. Accordingly, recent independent reports investigating the natural history of the disease in a long-term follow-up setting have shown that patients with SH have a higher incidence of cardiovascular events and related mortality. Moreover, longitudinal studies have also shown increased incidence of osteoporotic vertebral fractures. Future research is needed to improve the diagnostic performance of hormonal tests, by assessment of the complete steroid profile with more accurate assays, and to define the efficacy of surgical vs medical treatment in a randomized-controlled setting.

Abstract
Cushing's syndrome (CS) patients have increased mortality primarily due to cardiovascular events induced by glucocorticoid (GC) excess-related severe metabolic changes. Glucose metabolism abnormalities are common in CS due to increased gluconeogenesis, disruption of insulin signalling with reduced glucose uptake and disposal of glucose and altered insulin secretion, consequent to the combination of GCs effects on liver, muscle, adipose tissue and pancreas. Dyslipidaemia is a frequent feature in CS as a result of GC-induced increased lipolysis, lipid mobilisation, liponeogenesis and adipogenesis. Protein metabolism is severely affected by GC excess via complex direct and indirect stimulation of protein breakdown and inhibition of protein synthesis, which can lead to muscle loss. CS patients show changes in body composition, with fat redistribution resulting in accumulation of central adipose tissue. Metabolic changes, altered adipokine release, GC-induced heart and vasculature abnormalities, hypertension and atherosclerosis contribute to the increased cardiovascular morbidity and mortality. In paediatric CS patients, the interplay between GC and the GH/IGF1 axis affects growth and body composition, while in adults it further contributes to the metabolic derangement. GC excess has a myriad of deleterious effects and here we attempt to summarise the metabolic comorbidities related to CS and their management in the perspective of reducing the cardiovascular risk and mortality overall.

Abstract
BACKGROUND Subclinical Cushing's syndrome (SCS) is a condition of biochemical cortisol excess without the classical clinical features of overt hypercortisolism; it may be associated with some consequences of metabolic syndrome. The most appropriate treatment remains controversial. This study aimed to assess the outcomes of adrenalectomy for SCS. METHODS A systematic review was performed. MEDLINE, Embase and Cochrane Databases (1980-2013) were searched for studies reporting the outcomes of unilateral adrenalectomy with respect to hypertension, diabetes, dyslipidaemia, obesity and osteoporosis in patients with SCS. Studies with a questionable diagnosis of SCS, bilateral adrenal involvement and insufficient data were excluded. RESULTS Of the 105 papers screened, seven were selected; there were six retrospective studies and one randomized clinical trial, including 230 patients. Data analysis was limited by heterogeneity in definition of SCS and endpoints. Hypercortisolism was cured in all operated patients. Laparoscopy was the preferred approach, with a morbidity rate of 0·8 per cent. A beneficial effect of surgery on blood pressure, glucometabolic control and obesity was evident in all studies, with cure or improvement in 72, 46 and 39 per cent of patients respectively, compared with conservative management. The results for lipid metabolism were equivocal, because of a decrease in triglyceridaemia but discordant effects on cholesterol metabolism among the different studies. No beneficial effects on osteoporosis were found. CONCLUSION Laparoscopic adrenalectomy seems to be beneficial in reversing several metabolic effects of hypercortisolism, with a low morbidity rate. However, the heterogeneity and low quality of the available studies preclude definitive recommendations.

Abstract
BACKGROUND Management of subclinical Cushing's syndrome (SCS) remains controversial; it is not possible to predict which patients would benefit from adrenalectomy. In the present study we aimed to evaluate the role of adrenocortical scintigraphy (ACS) in the management of patients with SCS. METHODS The medical records of 33 consecutive patients with adrenal "incidentaloma" and proven or suspected SCS who underwent (131)I-19-iodocholesterol ACS between 2004 and 2010 were reviewed. Sixteen underwent laparoscopic adrenalectomy (surgical group-S-group) and 17 were medically managed (medical group-M-group). Follow-up evaluation was obtained by outpatient consultation. RESULTS Overall 25 patients (15 in the S-group and 10 in the M-group) had concordant unilateral uptake at ACS (ACS+). In the S-group, the mean follow-up duration was 30.9 ± 16.1 months and, irrespective of the presence of hormonal diagnosis of SCS, in patients who were ACS+ adrenalectomy resulted in a significant increase in HDL cholesterol and decreases in body mass index, glycemia, and blood pressure (BP). One patient reduced antihypertensive medication and three others were able to discontinue it altogether. Prolonged postoperative hypoadrenalism (PH) occurred in 14 patients in the S-group. The overall accuracy in predicting PH was 93.7 % for ACS and 68.7 % for laboratory findings. In the M-group, the mean follow-up duration was 31.5 ± 26.3 months and no patient developed overt Cushing's syndrome, although ACS+ patients experienced a worsening in glycemia and diastolic BP. CONCLUSIONS Adrenal scintigraphy seems the most accurate diagnostic test for SCS. It is able to predict the metabolic outcome and the occurrence of PH, identifying the patients who could benefit from adrenalectomy irrespective of hormonal diagnosis.

Abstract
CONTEXT The postoperative course of patients with subclinical hypercortisolism (SH) is yet to be clarified. The aims are to review the prevalence and predictive factors of postoperative adrenal insufficiency and the time to recover a normal adrenocortical function in patients with SH and Cushing's syndrome (CS). EVIDENCE ACQUISITION Using the PubMed database, we conducted a systematic review of the literature, selecting studies published from 1980 to 2013. EVIDENCE SYNTHESIS Of the 1522 papers screened, 28 were selected (13 retrospective, 14 prospective, and one randomized controlled trial). The prevalence of postoperative adrenal insufficiency was 65.3% in 248 SH subjects and 99.7% in 377 CS patients. Patients with SH were reclassified according to the following diagnostic criteria: subjects defined by pathological dexamethasone test only (DEX), and those defined by the dexamethasone test with one (DEX+1) or two additional criteria (DEX+2); and they were compared with CS patients. The prevalence of adrenal insufficiency was 51.4, 60.6, 91.3, and 99.7%, respectively, with no significant difference between the two latter groups. The test with the best compromise between sensitivity (64%) and specificity (81%) in predicting adrenal insufficiency was the midnight serum cortisol. The time to achieve eucortisolism was lower in SH patients than in CS patients (6.5 vs 11.2 mo; P < .001). CONCLUSIONS Adrenal insufficiency occurs in about half of the patients with SH if defined only by the pathological dexamethasone test. However, prevalence of adrenal insufficiency and time to recovery are tightly related to the degree of hypercortisolism and diagnostic criteria to define SH, which might help to better define SH for future studies.

Abstract
OBJECTIVE To investigate the possibility of a different prevalence of subclinical Cushing's syndrome (SCS) and potentially related morbidities between patients with unilateral adrenal incidentalomas (UAI) and bilateral adrenal incidentalomas (BAI), as existing data are few and controversial. DESIGN Prospective observational study. METHODS Clinical examination, biochemical tests, and hormonal evaluation were performed in 298 consecutive patients with adrenal incidentalomas, unilateral in 224 patients (75.2%), bilateral in 74 patients (24.8%), with apparently benign masses based on imaging characteristics and after exclusion of overt endocrine disease. The diagnosis of SCS was based on a post-dexamethasone suppression test (2 mg dexamethasone/24 h for 48 h), with serum cortisol level ≥1.8 μg/dl combined with at least one abnormal result of the other hormonal measurements. RESULTS SCS was diagnosed in 66 out of 298 (22.1%) patients, being more frequent in patients with BAI (35.1 vs 17.9%, P=0.003, for BAI and UAI respectively). Hypertension, type 2 diabetes mellitus, impaired glucose tolerance, and dyslipidemia were of a similar frequency in both groups. SCS patients with UAI and BAI did not differ in age, gender, BMI, waist circumference, and mass size. Factors related to SCS were the presence of BAI (OR, 3.24; 95% CI, 2.31-4.54) and mass size (OR, 2.63; 95% CI, 1.31-5.26). CONCLUSION BAI patients present more often with SCS when compared with UAI patients; however, morbidities potentially related to subtle cortisol hypersecretion were of a similar frequency in both groups. Further studies are needed to clarify whether this difference in hormonal activity may be related to different pathophysiologies.
