Impact of adrenalectomy on hypertension in patients with nonfunctional adrenal tumors: a retrospective study.

OBJECTIVE: To investigate the impact of adrenalectomy on hypertension in patients with nonfunctional adrenal tumors. SUBJECTS AND METHODS: Between January 2020 and October 2022, patients with adrenal lesions were retrospectively screened for nonfunctional adrenal tumors at the Zhongnan Hospital of Wuhan University. All patients underwent detailed endocrinological examination and computed tomography to characterize the lesions. One year after discharge, follow-up blood pressure (BP) was assessed and compared to the blood pressure on admission. Univariate analysis and multivariate regression analysis were performed to determine factors predicting favorable hypertension outcomes after adrenalectomy. RESULTS: A total of 309 patients were found to be eligible, including 123 who underwent adrenalectomy. Patients who underwent adrenalectomy were stratified into two groups: (Bancos I (2022) Adrenal Incidentalomas: Insights Into Prevalence. Ann Intern Med 175:1481-1482. https://doi.org/10.7326/M22-2600 ) those with improved hypertension (n = 71), and (Fassnacht M, Tsagarakis S, Terzolo M, Tabarin A, Sahdev A, Newell-Price J et al. (2023) European Society of Endocrinology clinical practice guidelines on the management of adrenal incidentalomas, in collaboration with the European Network for the Study of Adrenal Tumors. Eur J Endocrinol 189:G1-42. https://doi.org/10.1093/ejendo/lvad066 ) those without improved hypertension (n = 52). In contrast, the blood pressure levels of conservatively treated patients remained relatively stable 1 year after discharge. Univariate analysis and multivariate regression analysis showed that body mass index (BMI) and duration of hypertension were significantly different between the hypertension improvement group and the non-improvement group (p < 0.05). CONCLUSION: Adrenalectomy has been shown to be effective in improving hypertension in certain patients with nonfunctional adrenal tumors. BMI and duration of hypertension were independent factors associated with favorable hypertension outcomes after adrenalectomy.

Incidence, Presentation, and Natural History of Adrenal Hemorrhage: An Institutional Analysis.

INTRODUCTION: Adrenal hemorrhage (AH) can occur due to multiple etiologies with variable radiographic appearance, often indistinguishable from underlying adrenal neoplasms. There is a lack of AH literature and evidence-based guidelines. Our study aimed to understand the prevalence and etiology of AH, follow-up, and incidence of underlying neoplasm. METHODS: An institutional database was queried from January 2006 to October 2021 for patients with AH on imaging, excluding patients with known malignancies, adrenal masses, or prior adrenal surgery. Demographics, medical history, hematoma size, laterality, biochemical evaluation, intervention, and additional imaging were reviewed. RESULTS: Of 490,301 imaging reports queried, 530 (0.11%) with AH met inclusion criteria. Most imaging (n = 485, 91.5%) was performed during trauma evaluation. Two patients underwent dedicated intervention at presentation. Interval imaging was performed in 114 (21.5%) patients at a median of 2.6 (interquartile range 0.99-13.4) mo, with resolution (n = 84, 73.7%) or decreased size of AH (n = 21, 18.4%) in most patients. Only 10 patients (1.9%) saw an outpatient provider in our system to address AH or evaluate for underlying mass, and 9 (1.7%) underwent biochemical screening. Thirteen patients (11% of 118 patients with any follow-up) had evidence of an adrenal mass, confirmed on serial imaging (n = 10) or adrenalectomy (n = 3). Scans performed for nontrauma indications were significantly more likely to have an underlying mass (n = 6/26 [23.1%]) than those performed for trauma evaluation (n = 7/92 [7.6%], P = 0.04). CONCLUSIONS: AH is a rare finding associated with an increased rate of underlying adrenal mass, particularly when unrelated to trauma. Most AH resolves spontaneously without intervention. Follow-up imaging at 6 mo can help distinguish mass-associated AH from simple hemorrhage.

Identification of risk factors for postoperative persistent hypertension in patients with pheochromocytoma.

BACKGROUND: Surgical resection is the primary management for pheochromocytoma. However, some patients with pheochromocytoma still suffer from hypertension after successful adrenalectomy. The risk factors for postoperative persistent hypertension remain unclear. Thus the aim of the present study was to identify the risk factors of postoperative persistent hypertension in patients with pheochromocytoma concomitant with hypertension. METHODS: We retrospectively analyzed 259 patients with pheochromocytoma who underwent adrenalectomy in our hospital between January 1, 2007, and December 31, 2018. Patients' demographics, comorbidities, and perioperative data were recorded. The odds ratio (OR) and 95% confidence interval were measured through binary logistic regression. The cutoff values and the area under the curve (AUC) for continuous risk factors of persistent hypertension after adrenalectomy were calculated through receiver operating characteristic curve analysis. RESULTS: Of the 259 patients, 40.9% (106/259) patients experienced postoperative persistent hypertension. Three independent risk factors of persistent hypertension in patients with pheochromocytoma after adrenalectomy were found to be older age (OR = 1.16, p = 0.037), longer duration of hypertension (OR = 3.10, p = 0.01), and concomitance with cardiovascular events (yes vs. no, OR = 17.17, p = 0.049). The cutoff value of age and duration of hypertension was 66 years (AUC = 0.741, p < 0.0001) and 27 months (AUC = 0.991, p < 0.0001), respectively. CONCLUSIONS: Collectively, older age, a longer duration of hypertension, and concomitance with cardiovascular events were independent risk factors of persistent hypertension in patients with pheochromocytoma after adrenalectomy. These findings may help in improving perioperative management and follow-up strategies.

Pregnancies complicated with functioning adrenal adenomas causing severe obstetric outcomes: a 20-year experience at a tertiary center.

BACKGROUND: Functioning adrenal adenoma during pregnancy is rare, and the diagnosis is challenging owing to unspecific symptoms and restricted investigations. The obstetric outcomes of patients who undergo surgery during pregnancy or who receive only medical treatment are poorly described. OBJECTIVE: The aim was to investigate the associations between functioning adrenal adenomas and obstetric outcomes. METHODS: A retrospective study was performed in a tertiary center over 20 years. The clinical characteristics, management and obstetric outcomes of the diagnosed pregnant women were reviewed. RESULTS: A total of 12 women were diagnosed with functioning adrenal adenomas during pregnancy from January 2002 to September 2022. Eight women had cortisol-secreting adrenal adenomas, two had excessive catecholamine secretion, and two had primary aldosteronism. The initial symptoms of adrenal adenoma during pregnancy included hypertension or preeclampsia, gestational diabetes mellitus or prepregnancy diabetes mellitus, hypokalemia and ecchymosis. Four women underwent adrenalectomy during pregnancy, while 8 women received only medical therapy. Preterm birth occurred in all patients who received medicine, whereas 1 patient who underwent surgery experienced preterm birth. Among the 8 women in the medical treatment group, 3 had neonates who died. CONCLUSIONS: Once hypertension, hyperglycemia and hypokalemia occur during the 1st or 2nd trimester, pregnant women with adrenal adenomas should be evaluated via laboratory and imaging examinations. The maternal and fetal outcomes were unpredictable owing to the severity of adrenal adenoma, particularly in patients who received only medical treatment. Adrenalectomy should be recommended during pregnancy.

Uncommon adrenal rest tumors and massive adrenal enlargement in adult with congenital adrenal hyperplasia mimicking metastasis from pleomorphic sarcoma.

BACKGROUND: Congenital adrenal hyperplasia (CAH) encompassed a bunch of autosomal recessive disorders characterized by impaired cortisol levels due to an enzymatic deficiency in steroid synthesis. In adult male patients with CAH, a frequent complication related to poor disease control is the development of ectopic adrenocortical tissue in the testes, named testicular adrenal rest tumors (TART). Conversely, ovarian adrenal rest tumors (OART) in females are extremely rare and adrenal rests in sites other than gonads are so uncommon to have been described only few times in literature. CASE PRESENTATION: We report a case of a male patient with untreated CAH and oncologic history of pleomorphic sarcoma who presented with massive bilateral adrenal enlargement and adrenal rest tumors in peri-lumbar and peri-cecal sites, which mimicked metastasis from sarcoma. CONCLUSIONS: The development of massive adrenal enlargement and ectopic adrenal rest tumors in sites other than gonads, even if very uncommon, should be suspected in patients with CAH and prolonged periods of undertreatment.

A rare case of pheochromocytoma in a pregnant woman presenting with chest pain: extraordinary management.

BACKGROUND: Pheochromocytoma is rare in pregnant women. It presents as diverse symptoms, including hypertension and sweating. The symptoms of pregnant women with pheochromocytoma and comorbid hypertension often mimic the clinical manifestations of preeclampsia, and these women are often misdiagnosed with preeclampsia. CASE PRESENTATION: In this case, a pregnant woman presented with chest pain as the primary symptom, and a diagnosis of pheochromocytoma was considered after ruling out myocardial ischemia and aortic dissection with the relevant diagnostic tools. This patient then underwent successful surgical resection using a nontraditional management approach, which resulted in a positive clinical outcome. CONCLUSIONS: It is essential to consider pheochromocytoma as a potential cause of chest pain and myocardial infarction-like electrocardiographic changes in pregnant women, even if they do not have a history of hypertension.

Hypertension and cardiac damage in pheochromocytoma and paraganglioma patients: a large-scale single-center cohort study.

BACKGROUND: Hypertension (HT) is one of the most common manifestations in patients with catecholamine-secreting neuroendocrine tumors. Although the cardiovascular manifestations of these tumors have been described, there have been no large-scale investigations of the profile of HT and changes in cardiac structure and function that occur in patients with pheochromocytomas and paragangliomas (PPGL). MATERIALS AND METHODS: In this study, we investigated the prevalence of HT and left ventricular remodeling (LVR) in a cohort of 598 patients who underwent surgery for PPGL at our center between January 2001 and April 2022. Information on demographics, reason for hospitalization, medical history, biochemical parameters, findings on echocardiography, and tumor characteristics were recorded. The LVR index was compared according to whether or not there was a history of HT. RESULTS: The average age was 47.07 ± 15.07 years, and 277 (46.32%) of the patients were male. A history of HT was found in 423 (70.74%) of the 598 patients. Paraganglioma was significantly more common in the group with HT (26.00% vs. 17.71%, P = 0.030) and significantly less likely to be found incidentally during a health check-up in this group (22.93% vs. 59.43%, P < 0.001). Among 365 patients with complete echocardiography data, left ventricular mass index (86.58 ± 26.70 vs. 75.80 ± 17.26, P < 0.001) and relative wall thickness (0.43 ± 0. 08 vs. 0.41 ± 0.06, P = 0.012) were significantly higher in patients with PPGL and a history of HT. The proportions with left ventricular hypertrophy (LVH) (19.40% vs. 8.25%, P = 0.011) and LVR (53.73% vs. 39.18%, P = 0.014) were also higher when there was a history of HT. After adjusting for age, gender, body mass index, alcohol consumption, smoking status, diabetes, stroke, creatinine level, tumor location, and tumor size, a history of HT was significantly correlated with LVH (odds ratio 2.71, 95% confidence interval 1.18-6.19; P = 0.018) and LVR (odds ratio 1.83, 95% confidence interval 1.11-3.03; P = 0.018). CONCLUSION: HT is common in patients with PPGL (70.74% in this cohort). PPGL without a history of HT is more likely to be found incidentally (59.43% in our cohort). HT is associated with LVR in PPGL patients with complete echocardiography data. These patients should be observed carefully for cardiac damage, especially those with a history of HT.

Tumor enlargement in adrenal incidentaloma is related to glaucoma: a new prognostic feature?

PURPOSE: The uncertainty on the management of small adrenal incidentalomas (AIs) still represents a challenge in real clinical practice. Considering the lack of knowledge on risk factors implicated in tumour enlargement, the aim of this study was to identify risk factors for morphological changes during follow-up of adrenal incidentalomas (AIs). METHODS: We retrospectively evaluated demographic, clinical, radiological and biochemical parameters of 153 AIs (2007-2021). Patients with histological diagnosis of metastases or pheochromocytoma were excluded. To detect risk factors for tumor enlargement, diseases associated with AIs were included if their prevalence was higher than 2%. Patients were divided into two groups (A: radiological stability; B: tumor enlargement defined as > 5 mm/year in the main diameter). RESULTS: Group A: 89.5% and group B: 10.5%, mean follow-up 38.6 ± 6.9 months (range 6-240). Tumor enlargement when occurred was within 36 months of follow-up. In group B high body weight (p < 0.03), dehydroepiandrosterone sulfate (DHEAS) (p < 0.05) and direct renin concentration (DRC) (p < 0.04) were higher than group A, while aldosterone levels were lower; moreover, considering comorbidities, glaucoma and dysglycemia (p < 0.01 for both) had higher prevalence in group B. Glaucoma and dysglycemia were independent predictors of enlargement. Patients affected by glaucoma, atrial fibrillation, dysglycemia had a lower dimensional change-free survival than non-affected. CONCLUSIONS: Glaucoma might be a novel risk factor for AI enlargement. If subtle undetectable cortisol hypersecretion has a role is a topic for further research.

High-Titer Anti-ZSCAN1 Antibodies in a Toddler Clinically Diagnosed with Apparent Rapid-Onset Obesity with Hypothalamic Dysfunction, Hypoventilation, and Autonomic Dysregulation Syndrome.

Severe obesity in young children prompts for a differential diagnosis that includes syndromic conditions. Rapid-Onset Obesity with Hypothalamic Dysfunction, Hypoventilation, and Autonomic Dysregulation (ROHHAD) syndrome is a potentially fatal disorder characterized by rapid-onset obesity associated with hypoventilation, neural crest tumors, and endocrine and behavioral abnormalities. The etiology of ROHHAD syndrome remains to be established, but recent research has been focusing on autoimmunity. We report on a 2-year-old girl with rapid-onset obesity during the first year of life who progressed to hypoventilation and encephalitis in less than four months since the start of accelerated weight gain. The patient had a high titer of anti-ZSCAN1 antibodies (348; reference range < 40), and the increased values did not decline after acute phase treatment. Other encephalitis-related antibodies, such as the anti-NDMA antibody, were not detected. The rapid progression from obesity onset to central hypoventilation with encephalitis warns about the severe consequences of early-onset ROHHAD syndrome. These data indicate that serial measurements of anti-ZSCAN1 antibodies might be useful for the diagnosis and estimation of disease severity. Further research is needed to determine whether it can predict the clinical course of ROHHAD syndrome and whether there is any difference in antibody production between patients with and without tumors.

A Patient with Partial 17α-Hydroxylase Deficiency Initially Diagnosed with Asherman Syndrome and Pheochromocytoma.

This study present a case of a 49-year-old woman who suffered from resistant hypertension, hypokalemia, hypomenorrhea, and infertility. She was hospitalized 6 years earlier for hypomenorrhea and abdominal pain at the Xiamen Maternity and Child Health Hospital, where she was diagnosed with Asherman syndrome. During hospitalization, a computed tomography examination revealed an adrenal mass. She was referred to Xiamen University Affiliated Zhongshan Hospital for pheochromocytoma and underwent surgical resection of the left adrenal gland. The adrenal cortex adenoma was confirmed by pathological biopsy. Six years later, the patient also presented with hypertension and hypokalemia to our emergency department. A diagnosis of 17α-hydroxylase deficiency was established through the analysis of clinical and laboratory characteristics. The genetic analysis of CYP17A1 revealed compound heterozygous mutations, 1 of which was a mutation of c.1226 C>G, and the other c.297+2T>C.

Acute respiratory distress syndrome associated with a pheochromocytoma in an adult dog.

A 16-year-old castrated male shih tzu dog was brought to the emergency service because of an acute (24 h) history of gagging, coughing, and lethargy. Physical examination revealed dyspnea concurrent with diffuse, bilateral, pulmonary crackles and wheezes. Oxygen saturation, measured with a pulse oximeter, was < 95%. Thoracic radiographs revealed a multifocal alveolar pattern superimposed over a diffuse interstitial pattern with normal heart size. The dog continued to be dyspneic despite oxygen therapy. In accordance with the radiographic findings, further supportive care was recommended. Due to the unknown prognosis and financial constraints, the owner elected humane euthanasia. Necropsy confirmed a pheochromocytoma and lung changes without evidence of congestive heart failure. Findings were consistent with diffuse alveolar damage. These findings correlated with the dog's clinical diagnosis of acute respiratory distress syndrome (ARDS). No other disease processes associated with ARDS were identified. The purpose of this case report is to describe an unusual presentation of ARDS likely associated with a pheochromocytoma and confirmed by necropsy. Acute respiratory distress syndrome associated with a pheochromocytoma has been described in medical literature but has never been reported in veterinary medicine. Key clinical message: Pheochromocytomas should be added to the list of risk factors associated with ARDS in dogs. Dogs with a suspected diagnosis of pheochromocytoma whose owners elect against surgical removal should be closely monitored for an acute onset of respiratory distress, which could suggest the development of ARDS.

Syndrome de détresse respiratoire aiguë associé à un phéochromocytome chez un chien adulteUn chien shih tzu mâle castré de 16 ans a été amené aux services d'urgence en raison d'antécédents aigus (24 heures) de haut-le-coeur, de toux et de léthargie. L'examen physique a révélé une dyspnée concomitante à des crépitements et des respirations sifflantes diffuses, bilatérales et pulmonaires. La saturation en oxygène, mesurée avec un oxymètre de pouls, était < 95 %. Les radiographies thoraciques ont révélé un motif alvéolaire multifocal superposé à un motif interstitiel diffus avec une taille cardiaque normale. Le chien est resté dyspnéique malgré l'oxygénothérapie. Conformément aux résultats radiographiques, des soins de soutien supplémentaires ont été recommandés. En raison du pronostic inconnu et des contraintes financières, le propriétaire a opté pour l'euthanasie sans cruauté. La nécropsie a confirmé un phéochromocytome et des modifications pulmonaires sans signe d'insuffisance cardiaque congestive. Les résultats concordaient avec des lésions alvéolaires diffuses. Ces résultats étaient en corrélation avec le diagnostic clinique du syndrome de détresse respiratoire aiguë (ARDS) du chien. Aucun autre processus pathologique associé à l'ARDS n'a été identifié. Le but de ce rapport de cas est de décrire une présentation inhabituelle de l'ARDS probablement associée à un phéochromocytome et confirmée par la nécropsie. Le syndrome de détresse respiratoire aiguë associé à un phéochromocytome a été décrit dans la littérature médicale mais n'a jamais été rapporté en médecine vétérinaire.Message clinique clé:Les phéochromocytomes doivent être ajoutés à la liste des facteurs de risque associés à l'ARDS chez le chien. Les chiens avec un diagnostic suspecté de phéochromocytome dont les propriétaires choisissent de ne pas procéder à l'ablation chirurgicale doivent être étroitement surveillés pour détecter l'apparition aiguë d'une détresse respiratoire, ce qui pourrait suggérer le développement d'un ARDS.(Traduit par Dr Serge Messier).

[Clinical characteristics and prognosis of primary aldosteronism associated with subclinical Cushing syndrome].

Objective: To analyze the clinical characteristics and prognosis of patients with primary aldosteronism (PA) associated with subclinical Cushing syndrome (SCS). Methods: This retrospective cohort study was conducted at the First Affiliated Hospital of Chongqing Medical University in China. Patients with PA were included between January 2014 and December 2022. According to the results of 1-mg overnight dexamethasone suppression test, the patients were divided into the PA group and PA associated with SCS (PA/SCS) group. The demographic information, hormone levels, and follow-up results were analyzed. Independent sample t-test, chi-square test and Mann-Whitney U test were used for data comparison. Results: A total of 489 PA patients were enrolled in this study, of which 109 had PA/SCS (22.3%). Patients with SCS were on average older (54.4±10.7 vs. 47.4±11.0, P<0.001); had a larger proportion of women (69.7%, 76/109 vs. 57.4%, 218/380; P=0.020); and a longer duration of hypertension [96 (36, 180) vs. 60 (12, 120) months, P=0.001] than patients without SCS. There were 215 and 51 patients in the PA group and PA/SCS group, who completed adrenalectomy and follow-up, respectively. The remission rate of autonomous cortisol secretion in the PA/SCS group was 85.3% (29/34). There was no significant difference in the remission rate of autonomous aldosterone secretion among patients between the PA/SCS and PA group (94.1%, 48/51 vs. 94.4%, 203/215; P=1.000), while the clinical remission rate in the PA/SCS group was lower than that in the PA group (39.2%, 20/51 vs. 61.9%, 133/215; P=0.003). Conclusions: SCS is common in PA patients (22.3%), and the clinical remission rate is low. Screening using the 1-mg overnight dexamethasone suppression test is recommended for all patients with PA.

Endocrine Fever.

Fever is usually thought to be of an infectious or inflammatory etiology. In this brief communication, we explore the multifaceted connections between fever and endocrine dysfunction. Impaired resistance to infection often leads to fever in conditions like diabetes and Cushing's syndrome. Additionally, several endocrine disorders, including hyperthyroidism, subacute thyroiditis, carcinoid syndrome, and pheochromocytoma, can manifest as fever. Furthermore, fever can be an adverse effect of various endocrine treatments, such as bisphosphonates and antithyroid drugs. We refer to these scenarios as 'endocrine fever.' Increased awareness of these clinical associations can aid in prompt diagnosis and management of these conditions.

New advances in endocrine hypertension: from genes to biomarkers.

Hypertension (HT) is a major cardiovascular risk factor that affects 10% to 40% of the general population in an age-dependent manner. Detection of secondary forms of HT is particularly important because it allows the targeted management of the underlying disease. Among hypertensive patients, the prevalence of endocrine HT reaches up to 10%. Adrenal diseases are the most frequent cause of endocrine HT and are associated with excess production of mineralocorticoids (mainly primary aldosteronism), glucocorticoids (Cushing syndrome), and catecholamines (pheochromocytoma). In addition, a few rare diseases directly affecting the action of mineralocorticoids and glucocorticoids in the kidney also lead to endocrine HT. Over the past years, genomic and genetic studies have allowed improving our knowledge on the molecular mechanisms of endocrine HT. Those discoveries have opened new opportunities to transfer knowledge to clinical practice for better diagnosis and specific treatment of affected subjects. In this review, we describe the physiology of adrenal hormone biosynthesis and action, the clinical and biochemical characteristics of different forms of endocrine HT, and their underlying genetic defects. We discuss the impact of these discoveries on diagnosis and management of patients, as well as new perspectives related to the use of new biomarkers for improved patient care.

Cardio-metabolic pathophysiology in mild glucocorticoid excess: Potential implications for management of adrenal incidentaloma.

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.

Characterisation of the urinary steroid profile of patients with nonfunctioning adrenal incidentalomas: A matched controlled cross-sectional study.

AIM: To identify alterations in steroid metabolism in patients with nonfunctioning adrenal incidentalomas (NFAIs) through the analysis of their urinary steroid profile (USP). METHODS: Cross-sectional study with one study group (NFAIs, cortisol post dexamethasone suppression test [DST] ≤ 1.8 µg/dl [49.7 nmol/L]) and 2 control groups: patients with autonomous cortisol secretion (ACS group, cortisol post-DST > 1.8 µg/dl (49.7 nmol/L) and patients without adrenal tumours (healthy-adrenal group). Twenty-four-hour urine collections for USP measurement (total and free fraction of 51 24 h-urine specimens) were obtained from 73 participants (24 with NFAIs, 24 without AIs, and 25 with ACS). USP was determined by gas chromatography coupled to mass spectrometry. Patients of the three groups were matched according to sex, age (±5 years-old) and body mass index (±5 kg/m2 ). RESULTS: Compared to healthy-adrenal controls, patients with NFAIs had a lower excretion of androgen metabolites (230.5 ± 190.12 vs. 388.7 ± 328.58 µg/24 h, p = .046) and a higher excretion of urinary free cortisol (UFC) (54.3 ± 66.07 vs. 25.4 ± 11.16 µg/24 h, p = .038). UFC was above the reference range in 20.8% of patients in the NFAI, compared to 0% in the healthy-adrenal group (p = .018). Patients with ACS had a higher prevalence of hypertension, dyslipidemia, and diabetes than patients with NFAIs or the control group. A lower excretion of androgen metabolites (218.4 ± 204.24 vs. 231 ± 190 µg/24 h, p = .041) and a nonsignificant higher excretion of glucocorticoid metabolites (2129.6 ± 1195.96 vs. 1550.8 ± 810.03 µg/24 h, p = .180) was found in patients with ACS compared to patients with NFAIs. CONCLUSION: NFAIs seem to secrete a subtle, yet clinically relevant, excess of glucocorticoids. Future studies are needed to confirm our findings; and to identify metabolic alterations associated with an increased cardiometabolic risk.

Adrenal incidentaloma: Do patients with apparently nonfunctioning mass or autonomous cortisol secretion have similar or different clinical and metabolic features?

OBJECTIVE: Although there is growing evidence associating nonfunctioning adrenal incidentalomas (NFAI) with cardiovascular risk factors, there are limited data whether NFAI and autonomous cortisol secretion (ACS) groups have similar or different clinical and metabolic features. The aim of this study is to compare cardiometabolic clinic parameters among patients with ACS and NFAI, as well as controls. DESIGN: Cross-sectional study. PATIENTS: Eighty nine NFAI, 58 ACS and 64 controls were evaluated. MEASUREMENTS: Diagnosis of NFAI (1 mg dexamethasone suppression test [1 mg-DST] ≤50 nmol/L [≤1.8 µg/dl]) and ACS (1 mg-DST > 50 nmol/L [> 1.8 µg/dl]) was established according to current guidelines. The control group was selected based on a normal adrenal imaging exam. RESULTS: There were no differences between groups regarding age, gender, ethnicity, menopause or body mass index. Patients with adrenal incidentaloma presented higher frequency of hypertension (74.1 vs. 57.8%; p = .02), resistant hypertension (45.4 vs. 9.4%; p < .001), dyslipidemia (80.1 vs. 63.9%; p = .01), as well as metabolic syndrome (84.2 vs. 61.7%; p = .001) compared to the controls, respectively. NFAI and ACS patients presented similar frequency of arterial hypertension (70.8 vs. 79.3%) and resistant hypertension (41.3 vs. 51.1%), dyslipidemia (79.3 vs. 81.5%) and metabolic syndrome (83.3 vs. 85.7%); also, levels of HbA1c were similar between the groups. Binary logistic regression showed that NFAI (p = .004) and ACS (p = .001) were independent predictors for resistant hypertension (p = .003); also, ACS was an independent predictor for metabolic syndrome (p = .04). CONCLUSIONS: NFAI and ACS presented a higher frequency of cardiometabolic morbidities in comparison with individuals with normal adrenal glands. Additionally, we demonstrated that both ACS and NFAI groups have similar cardiometabolic conditions.

Radiation of bilateral adrenal metastases is associated with a high risk of primary adrenal insufficiency.

BACKGROUND: Adrenal metastasis is the most common adrenal malignancy and can be bilateral in up to 43% of patients. Radiotherapy (RT) is one option available to treat adrenal metastases. The risk of primary adrenal insufficiency (PAI) after adrenal RT is unclear. OBJECTIVE: Determine the incidence and the timeline of PAI in patients undergoing adrenal RT. DESIGN, SETTING AND PARTICIPANTS: Single-centre longitudinal retrospective cohort study of adult patients with adrenal metastases treated with RT between 2010 and 2021. RESULTS: Of 56 patients with adrenal metastases treated with adrenal RT, eight (14.3%) patients developed PAI at a median of 6.1 months (interquartile range [IQR]: 3.9-13.8) after RT All patients developing PAI had either unilateral RT in the setting of contralateral adrenalectomy or bilateral adrenal RT. Patients who developed PAI received a median RT dose of 50 Gy (IQR: 44-50 Gy), administered in a median of five fractions (IQR: 5-6). Treated metastases decreased in size and/or metabolic activity on positron emission tomography in seven patients (87.5%). Patients were initiated on hydrocortisone (median daily dose of 20 mg, IQR: 18-40) and fludrocortisone (median daily dose of 0.05 mg, IQR: 0.05-0.05 mg). At the end of the study period, five patients died, all due to extra-adrenal malignancy, at a median time of 19.7 months (IQR: 16-21.1 months) since RT and median time of 7.7 months (IQR: 2.9-12.5 months) since the diagnosis of PAI. CONCLUSION: Patients receiving unilateral adrenal RT with two intact adrenal glands have a low risk of PAI. Patients receiving bilateral adrenal RT have a high risk of PAI and require close monitoring.

The degree of cortisol secretion is associated with diabetes mellitus and hypertension in patients with nonfunctioning adrenal tumors.

BACKGROUND: Similarly to cortisol-secreting adrenal tumors, also non-functioning adrenal tumors (NFAT) may be associated with an increased cardiovascular risk. We assessed in NFAT patients: (i) the association between hypertension (HT), diabetes mellitus (DM), obesity (OB), dyslipidemia (DL) and cardiovascular events (CVE) and cortisol secretion; (ii) the cut-off of the cortisol secretion parameters for identifying NFAT patients with a worse cardiometabolic profile. PATIENTS AND METHODS: In 615 NFAT patients (with cortisol levels after 1 mg overnight dexamethasone suppression test, F-1mgDST < 1.8 µg/dL [50 nmol/L]) F-1mgDST and adrenocorticotroph hormone (ACTH) levels and data on HT, DM, OB, DL and CVEs prevalence were retrospectively collected. RESULTS: HT, DM and HT plus DM were associated with F-1mgDST levels (area under the ROC curve: 0.588 ± 0.023, 0.610 ± 0.028, 0.611 ± 0.033, respectively, p < 0.001 for all comparisons) but not with ACTH. The cut-off for identifying patients with either HT or DM or HT plus DM was set at ≥ 1.2 µg/dL (33 nmol/L). As compared with patients with F-1mgDST < 1.2 µg/dL (n = 289), patients with F-1mgDST 1.2-1.79 µg/dL (33-49.4 nmol/L) (n = 326) had lower ACTH levels (17.7 ± 11.9 vs 15.3 ± 10.1 pg/mL, respectively, p = 0.008), older age (57.5 ± 12.3 vs 62.5 ± 10.9 years, respectively, p < 0.001), and higher prevalence of HT (38.1% vs 52.5% respectively p < 0.001), DM (13.1% vs 23.3%, respectively, p = 0.001), HT plus DM (8.3% vs 16.9%, respectively, p < 0.002) and CVE (3.2% vs 7.3%, respectively, p = 0.028). F-1mgDST 1.2-1.79 µg/dL was associated with either HT (odd ratio, OR, 1.55, 95% confidence interval, 95% CI 1.08-2.23, p = 0.018) or DM (OR 1.60, 95% CI 1.01-2.57, p = 0.045) after adjusting for age, gender, OB, DL, and DM (for HT) or HT (for DM), and with the presence of HT plus DM (OR 1.96, 95% CI 1.12-3.41, p = 0.018) after adjusting for age, gender, OB and DL. CONCLUSIONS: In NFAT patients, F-1mgDST 1.2-1.79 µg/dL seems to be associated with a higher prevalence of HT and DM and a worse cardiometabolic profile, even if the poor accuracy of these associations suggests caution in interpreting these results.

Surgical treatment of adrenal tumors during pregnancy.

While most adrenal tumors are identified incidentally and are non-functional, hormone-secreting tumors can cause morbidity and mortality. Hemodynamic lability and hypertension in pregnancy are associated with worse maternal and fetal outcomes. Achieving a diagnosis of hormone excess due to adrenal tumors can be clinically more difficult in the gravid patient due to normal physiologic alterations in hormones and symptoms related to pregnancy. This review focuses on some nuances of the diagnostic work-up, perioperative care, and surgical management of adrenally-mediated cortisol excess, primary aldosteronism, and pheochromocytoma and paraganglioma in the pregnant patient.
