RESUMEN
BACKGROUND: Secondary adrenal insufficiency (SAI) may occur in patients after unilateral adrenalectomy for adrenal-dependent hypercortisolism (HC) or primary aldosteronism (PA). This study aimed to assess whether postoperative day (POD) 1 basal cortisol was predictive of an abnormal cosyntropin stimulation test (CST) result and the need for glucocorticoid replacement (GR). METHODS: A retrospective review of consecutive patients who underwent unilateral adrenalectomy for HC, PA, or both between September 2014 and September 2022 was performed. On POD1, CST was performed for all the patients with HC, and before 2021 for all the patients with PA. The patients with an abnormal CST result were deemed at risk of SAI and discharged with GR. Receiver operating characteristic (ROC) curves were generated to evaluate the sensitivity (SN) and specificity (SP) of basal cortisol thresholds to predict an abnormal CST result. RESULTS: The patients underwent unilateral adrenalectomy for overt hypercortisolism (OH; n = 42), mild autonomous cortisol excess (MACE; n = 70), mixed PA/HC (n = 22), or PA (n = 73). On POD1, CST was performed for 152 patients (93% OH, 96% MACE,73% PA/HC, 41% PA), and 80 patients (53%) had SAI (67% OH, 55% MACE, 44% PA/HC, 33% PA). The SN and SP of a basal cortisol level of 10 µg/dL or lower to predict an abnormal CST were respectively 92% and 77% for OH, 94% and 73% for MACE, 100% and 85% for PA, and 100% and 67% for PA/HC. The optimal basal cortisol level for predicting an abnormal CST for patients with PA or PA/HC was 5 µg/dL or lower (SN/SP, 100%). CONCLUSIONS: After unilateral adrenalectomy for HC, PA, or mixed PA/HC, POD1 CST improved identification of patients at risk for SAI compared with basal cortisol levels alone. The authors recommend that POD1 CST be performed to determine the risk for SAI and the need for postoperative GR after unilateral adrenalectomy for patients with HC.
RESUMEN
OBJECTIVE: Since Cushing's disease (CD) is less common in the paediatric age group than in adults, data on this subject are relatively limited in children. Herein, we aim to share the clinical, diagnostic and therapeutic features of paediatric CD cases. DESIGN: National, multicenter and retrospective study. PATIENTS: All centres were asked to complete a form including questions regarding initial complaints, physical examination findings, diagnostic tests, treatment modalities and follow-up data of the children with CD between December 2015 and March 2017. MEASUREMENTS: Diagnostic tests of CD and tumour size. RESULTS: Thirty-four patients (M:F = 16:18) from 15 tertiary centres were enroled. The most frequent complaint and physical examination finding were rapid weight gain, and round face with plethora, respectively. Late-night serum cortisol level was the most sensitive test for the diagnosis of hypercortisolism and morning adrenocorticotropic hormone (ACTH) level to demonstrate the pituitary origin (100% and 96.8%, respectively). Adenoma was detected on magnetic resonance imaging (MRI) in 70.5% of the patients. Transsphenoidal adenomectomy (TSA) was the most preferred treatment (78.1%). At follow-up, 6 (24%) of the patients who underwent TSA were reoperated due to recurrence or surgical failure. CONCLUSIONS: Herein, national data of the clinical experience on paediatric CD have been presented. Our findings highlight that presenting complaints may be subtle in children, the sensitivities of the diagnostic tests are very variable and require a careful interpretation, and MRI fails to detect adenoma in approximately one-third of cases. Finally, clinicians should be aware of the recurrence of the disease during the follow-up after surgery.

INTRODUCTION: Adrenalectomy generally has favorable outcomes. It is unknown if patients with functional adrenal tumors experience different clinical outcomes than those with benign adrenal tumors, due to the presence of comorbid conditions secondary to the functional tumor. We investigated outcomes following open and laparoscopic adrenalectomy for benign nonfunctional (BNF) versus functional adrenal masses. METHODS: Patients undergoing adrenalectomy were identified in the 2015-2020 National Surgical Quality Improvement Program database, then categorized as BNF, hyperaldosteronism, hypercortisolism, and pheochromocytoma. The primary outcome of interest was 30-d morbidity and secondary outcomes included 30-d mortality, 30-d readmission, and postoperative length of stay (LOS). Subgroup analysis was performed based upon surgical approach. Univariate analysis was performed, followed by multivariable logistic regression for individual outcomes that differed significantly between patients with BNF and functional neoplasm, factoring in patient demographics and operative approach with statistical significance on univariate analysis. Descriptive statistics and outcomes were analyzed using Pearson's χ2 test and Mann-Whitney U-test as appropriate. RESULTS: There were 3291 patients with BNF while 484 had hyperaldosteronism, 263 hypercortisolism, and 46 pheochromocytomas. Within the laparoscopic group of 3615 (88.5%) of adrenalectomy patients, compared to BNF patients, patients with hyperaldosteronism had lower rates of postoperative morbidity (1.9% versus 5.2%, P < 0.001) and shorter LOS (1 d, interquartile range (IQR) [1-1] versus 1d IQR [1-2], P = 0.003); these persisted on multivariate analysis (OR 0.32, 95% confidence interval [CI] 0.14-0.74 and odds ratio 0.47, 95% CI 0.36-0.60, P < 0.001). Patients with hypercortisolism had higher morbidity (7.3% versus 5.2%, P < 0.001), 30-d readmission rates (5.3% versus 2.9%, P = 0.042) and longer LOS (2d, IQR [1-3] versus 1d, IQR [1-2, P < 0.001). On multivariate analysis, presence of hypercortisolism was independently associated with increased likelihood of readmission within 30 d (OR 2.20, 95% CI 1.11-2.99, P = 0.012) and longer LOS (>1 d) (OR 1.79, 95% CI 1.33-2.40, P < 0.001). Compared to BNF patients, patients with pheochromocytoma had higher rates of postoperative morbidity (6.2% versus 5.2%, P < 0.001). Within the open group of 469 (11.5% of adrenalectomy patients), there were no statistically significant differences in outcomes between patients with BNF and functional adrenal masses. CONCLUSIONS: Outcomes after adrenalectomy performed for functional neoplasms differ based on surgical indication.

PURPOSE: This study was undertaken to assess the unmet needs within the endogenous Cushing's syndrome (CS) care paradigm from the endocrinologist's perspective, including data abstracted from patient charts. The study evaluated endocrinologists' perceptions on burden of illness and treatment rationale along with the long-term clinical burden of CS, tolerability of CS treatments, and healthcare resource utilization for CS. METHODS: Retrospective medical chart data from treated patients with a confirmed diagnosis of CS was abstracted using a cross-sectional survey to collect data from qualified endocrinologists. The survey included a case report form to capture patient medical chart data and a web-enabled questionnaire to capture practitioner-level data pertaining to endocrinologists' perceptions of disease burden, CS treatments, and treatment attributes. RESULTS: Sixty-nine endocrinologists abstracted data from 273 unique medical charts of patients with CS. Mean patient age was 46.5 ± 13.4 years, with a 60:40 (female:male) gender split. The mean duration of endogenous CS amongst patients was 4.1 years. Chart data indicated that patients experienced a high burden of comorbidities and symptoms, including fatigue, weight gain, and muscle weakness despite multi-modal treatment. When evaluating treatments for CS, endocrinologists rated improvement in health-related quality of life (HRQoL) as the most important treatment attribute (mean score = 7.8; on a scale of 1 = Not at all important to 9 = Extremely important). Surgical intervention was the modality endocrinologists were most satisfied with, but they agreed that there was a significant unmet treatment need for patients with CS. CONCLUSION: Endocrinologists recognized that patients with CS suffered from a debilitating condition with a high symptomatic and HRQoL burden and reported that improvement in HRQoL was the key treatment attribute influencing their treatment choices. This study highlights unmet needs for patients with CS. Patients with CS have a high rate of morbidity and comorbidity, even after treatment.

Bone impairment associated with Cushing's disease (CD) is a complex disorder, mainly involving deterioration of bone quality and resulting in an increased fracture rate, often despite normal bone mineral density. Bone complications are common in patients with CD at the time of diagnosis but may persist even after successful treatment. There is currently no agreement on the optimal diagnostic methods, thresholds for anti-osteoporotic therapy and its timing in CD. In this review, we summarize the current data on the pathophysiology, diagnostic approach and management of bone complications in CD.
RESUMEN
CONTEXT: Once hypercortisolemia is confirmed, differential diagnosis between Cushing's syndrome (CS) due to neoplastic endogenous hypercortisolism and non-neoplastic hypercortisolism (NNH, pseudo-Cushing's syndrome) is crucial. Due to worldwide corticotropin-releasing hormone (CRH) unavailability, accuracy of alternative tests to dexamethasone (Dex)-CRH, is clearly needed. OBJECTIVE: Assess the diagnostic accuracy of Dex-CRH test, desmopressin stimulation test, midnight serum cortisol (MSC), and late-night salivary cortisol (LNSC) levels to distinguish CS from NNH. METHODS: Articles through March 2022 were identified from Scopus, Web of Science, MEDLINE, EMBASE, and PubMed. All steps through the systematic review were performed independently and in duplicate and strictly adhered to the updated PRISMA-DTA checklist. DATA SYNTHESIS: A total of 24 articles (1900 patients) were included. Dex-CRH had a pooled sensitivity and specificity of 91% (95%CI 87-94%; I2 0%) and 82% (73-88%; I2 50%), desmopressin test 86% (81-90%; I2 28%) and 90% (84-94%; I2 15%), MSC 91% (85-94%; I2 66%) and 81% (70-89%; I2 71%), and LNSC 80% (67-89%; I2 57%) and 90% (84-93%; I2 21%), respectively. Summary receiver operating characteristics areas under the curve were Dex-CRH 0.949, desmopressin test 0.936, MSC 0.942, and LNSC 0.950 without visual or statistical significance. The overall risk of studies bias was moderate. CONCLUSION: Dex-CRH, the desmopressin stimulation test, and MSC have similar diagnostic accuracy, with Dex-CRH and MSC having slightly higher sensitivity, and the desmopressin test being more specific. LNSC was the least accurate, probably due to high heterogeneity, intrinsic variability, different assays, and lack of consistent reported cutoffs. When facing this challenging differential diagnosis, the results presented here should increase clinicians' confidence when deciding which test to perform.

PURPOSE: Screening of Cushing Syndrome (CS) and Mild Autonomous Cortisol Secretion (MACS) in hypertensive patients is crucial for proper treatment. The aim of the study was to investigate screening and management of hypercortisolism among patients with hypertension in Italy. METHODS: A 10 item-questionnaire was delivered to referral centres of European and Italian Society of Hypertension (ESH and SIIA) in a nationwide survey. Data were analyzed according to type of centre (excellence vs non-excellence), geographical area, and medical specialty. RESULTS: Within 14 Italian regions, 82 centres (30% excellence, 78.790 patients during the last year, average 600 patients/year) participated to the survey. Internal medicine (44%) and cardiology (31%) were the most prevalent medical specialty. CS and MACS were diagnosed in 313 and 490 patients during the previous 5 years. The highest number of diagnoses was reported by internal medicine and excellence centres. Screening for hypercortisolism was reported by 77% in the presence of specific features of CS, 61% in resistant hypertension, and 38% in patients with adrenal mass. Among screening tests, the 24 h urinary free cortisol was the most used (66%), followed by morning cortisol and ACTH (54%), 1 mg-dexamethasone suppression test (49%), adrenal CT or MRI scans (12%), and late night salivary cortisol (11%). Awareness of referral centres with expertise in management of CS was reported by 67% of the participants, which reduced to 44% among non-excellence centres. CONCLUSIONS: Current screening of hypercortisolism among hypertensive patients is unsatisfactory. Strategies tailored to different medical specialties and type of centres should be conceived.
RESUMEN
CONTEXT: Cushing syndrome (CS) is associated with different hematological abnormalities. Nevertheless, conflicting data about erythropoiesis in CS have been reported. Furthermore, it is unclear whether CS sex and subtype-specific alterations in red blood cells (RBC) parameters are present. OBJECTIVE: To investigate sex and subtype-specific changes in RBC in patients with CS at initial diagnosis and after remission. DESIGN: Retrospective, monocentric study including 210 patients with CS (women, n = 162) matched 1:1 for sex and age to patients with pituitary microadenomas or adrenal incidentalomas (both hormonally inactive). RBC parameters were evaluated at initial diagnosis and after remission. RESULTS: Women with CS had higher hematocrit (median 42.2 vs 39.7%), hemoglobin (14.1 vs 13.4 g/dl) and mean corpuscular volume (MCV) (91.2 vs 87.9 fl) compared to the controls (all p < 0.0001). Women with Cushing disease (CD) showed higher hematocrit, RBC and hemoglobin levels than those with ectopic Cushing (ECS) (all p < 0.005). Men with CS had lower hematocrit (42.9 vs 44.7%), RBC count (4.8 vs 5.1n*106/µl) and hemoglobin (14.2 vs 15.4 g/dl), but higher MCV (90.8 vs 87.5 fl) than controls (all p < 0.05). In men with CS, no subtype-specific differences were identified. Three months after remission hemoglobin decreased in both sexes. CONCLUSION: CS is characterized by sexual and subtype-specific differences in RBC parameters. Compared to controls, women with CS showed higher hematocrit/hemoglobin levels, whereas men had lower hematocrit/hemoglobin, which further decreased directly after remission. Therefore, anemia should be considered as complication of CS in men. In women, differences in RBC parameters may help to differentiate CD from ECS.

BACKGROUND: Opportunistic infection is an under-recognized complication of Cushing's syndrome, with infection due to atypical mycobacterium rarely reported. Mycobacterium szulgai commonly presents as pulmonary infection, with cutaneous infection seldom reported in the literature. CASE PRESENTATION: 48-year-old man with a newly-diagnosed Cushing's syndrome secondary to adrenal adenoma presented with a subcutaneous mass on the dorsum of his right hand, was diagnosed with cutaneous Mycobacterium szulgai infection. The most likely source of the infection was through minor unnoticed trauma and inoculation from a foreign body. The patient's Cushing's syndrome, high serum cortisol levels and secondary immune suppression facilitated mycobacterial replication and infection. The patient was successfully treated with adrenalectomy, surgical debridement of cutaneous lesion, and a combination of rifampicin, levofloxacin, clarithromycin, and ethambutol for 6 months. There were no signs of relapse one year after cessation of anti-mycobacterial treatment. A literature review on cutaneous M. szulgai infection to further characterize the clinical characteristics of this condition, identified 17 cases of cutaneous M. szulgai infection in the English literature. Cutaneous M. szulgai infections with subsequent disease dissemination are commonly reported in immunocompromised hosts (10/17, 58.8%), as well as in immunocompetent patients with a history of breached skin integrity, such as invasive medical procedures or trauma. The right upper extremity is the most commonly involved site. Cutaneous M. szulgai infection is well controlled with a combination of anti-mycobacterial therapy and surgical debridement. Disseminated infections required a longer duration of therapy than localized cutaneous infections. Surgical debridement may shorten the duration of antibiotics. CONCLUSIONS: Cutaneous M. szulgai infection is a rare complication of adrenal Cushing's syndrome. Further studies are needed to provide evidence-based guidelines on the best combination of anti-mycobacterial and surgical therapy for managing this rare infective complication.

PURPOSE: The endogenous hypercortisolism that characterizes Cushing's syndrome (CS) is associated with a state of hypercoagulability that significantly increases the risk of thromboembolic disease, especially, venous events. Despite this certainty, there is no consensus on the best thromboprophylaxis strategy (TPS) for these patients. Our aim was to summarize the published data about different thromboprophylaxis strategies, and to review available clinical tools assisting thromboprophylaxis decision making. METHODS: Narrative review of thromboprophylaxis strategies in patients with Cushing's syndrome. A search was carried out on PubMed, Scopus and EBSCO until November 14th, 2022, and articles were selected based on their relevance and excluded in case of redundant content. RESULTS: Literature is scarce regarding thromboprophylaxis strategies to be adopted in the context of endogenous hypercortisolism, most often being a case-by-case decision according to the centre expertise. Only three retrospective studies, with a small number of patients enrolled, evaluated the use of hypocoagulation for the thromboprophylaxis of patients with CS in the post-operative period of transsphenoidal surgery and/or adrenalectomy, but all of them with favourable results. The use of low molecular weight heparin is the most frequent option as TPS in CS context. There are numerous venous thromboembolism risk assessment scores validated for different medical purposes, but just one specifically developed for CS, that must be validated to ensure solid recommendations in this context. The use of preoperative medical therapy is not routinely recommended to decrease the risk of postoperative venous thromboembolic events. The peak of venous thromboembolic events occurs in the first three months post-surgery. CONCLUSION: The need to hypocoagulate CS patients, mainly in the post-operative period of a transsphenoidal surgery or an adrenalectomy, is undoubtable, especially in patients with an elevated risk of venous thromboembolic events, but the precise duration and the hypocoagulation regimen to institute is yet to be determined with prospective studies.
RESUMEN
PURPOSE: ACTH-secreting pheochromocytoma is a rare cause of ectopic Cushing's syndrome, posing a clinical challenge for the severity of its clinical presentation, the difficulty in the prevention and the management of surgical complications. Sparse data are currently available about the optimal preoperative management of the severe symptoms due to both hypercortisolism and catecholamine excess, especially regarding the role and timing of medical therapies. METHODS: We present a series of three patients with ACTH-secreting pheochromocytoma. A brief review of the available literature evidence on the preoperative management of this rare clinical condition is also conducted. DISCUSSION: Patients with ACTH-secreting pheochromocytoma show peculiarities as compared to other forms of ACTH-dependent Cushing's syndrome, in terms of clinical presentation, preoperative management, and peri- and post-surgical short-term outcome. Pheochromocytoma should be ruled out in patient with ectopic CS of unknown origin because of the high anesthesiologic risk of proceeding to surgery with an undiagnosed pheochromocytoma. Proper preoperative recognition of complications of both hypercortisolism and catecholamines excess is the key to prevent the morbidity and mortality of an ACTH-producing pheochromocytoma. In these patients the absolute priority is to control excessive cortisol secretion since the rapid correction of the hypercortisolism is the most effective treatment of all the related comorbidities and it is mandatory to prevent severe complications during surgery, opting if necessary for a "block-and-replace" regimen. CONCLUSION: Our additional cases and this literature review could provide a better understanding of the complications to be evaluated at diagnosis and some suggestions on their management during the preoperative period.

PURPOSE: Simple screening tests to determine whether Cushing's syndrome (CS) should be ruled out are lacking. Tools that enable early diagnosis could reduce morbidity and associated sequelae. The potential of glucocorticoid-induced changes in the white blood cell (WBC) count for raising suspicion of CS is assessed. METHODS: This was a retrospective caseâcontrol study. The WBC counts of 73 cases with CS and 146 matched controls were compared. The number of leukocytes (Leu), the number and percentage of neutrophils (N, Np), the number and percentage of lymphocytes (L, Lp), neutrophil-to-lymphocyte differences in the number and percentage (N-L, Np-Lp), neutrophil-to-lymphocyte ratio in the number and percentage (NLR, NLRp), and leukocyte-to-lymphocyte differences (Leu-L) were evaluated. The area under the ROC curve (AUC) was calculated for each of these parameters. Reference values were estimated that could help disclose occult CS. RESULTS: All ten parameters showed significant differences between cases and controls. The AUC was greater than 0.7 for all ten parameters, and was the best for the NLRp and Lp (AUC: 0.89). An Lp of 23.9% showed a diagnostic accuracy of 84.9% for the diagnosis of CS. The concordance of an Lp below 24% and more than 8000 leucocytes had a PPV of 78.2% for CS, while the pairing of an Lp over 24% and a Leu below 8000 cells had an NPV of 97.3% for CS. CONCLUSION: WBC count assessment can be an effective tool to raise suspicion of CS, prompting diagnostic testing. This simple and universally available test may allow earlier diagnosis of CS before highly evolved phenotypes develop.

PURPOSE: The clinical and hormonal overlap between neoplastic (CS) and non-neoplastic (NNH/pCS) hypercortisolism is a challenge. Various dynamic tests have been proposed to allow an early discrimination between these conditions, but to date there is no agreement on which of them should be used. AIM: To provide an overview of the available tests and to obtain a quantitative synthesis of their diagnostic performance in discriminating NNH/pCS from CS. METHODS: The included articles, published between 1990 and 2022, applied one or more second line tests to differentiate NNH/pCS from CS patients. For the NNH/pCS group, we admitted the inclusion of patients presenting clinical features and/or biochemical findings suggestive of hypercortisolism despite apparent lack of a pCS-related condition. RESULTS: The electronic search identified 339 articles. After references analysis and study selection, we identified 9 studies on combined dexamethasone-corticotropin releasing hormone (Dex-CRH) test, 4 on Desmopressin test and 3 on CRH test; no study on Dex-Desmopressin met the inclusion criteria. Dex-CRH test provided the highest sensitivity (97%, 95 CI% [88%; 99%]). CRH tests showed excellent specificity (99%, 95% CI [0%; 100%]), with low sensitivity. Although metaregression analysis based on diagnostic odds ratio failed to provide a gold standard, CRH test (64.77, 95% CI [0.15; 27,174.73]) seemed to lack in performance compared to the others (Dex-CRH 138.83, 95% CI [49.38; 390.32] and Desmopressin 110.44, 95% CI [32.13; 379.63]). DISCUSSION: Both Dex-CRH and Desmopressin tests can be valid tools in helping discrimination between NNH/pCS and CS. Further studies are needed on this topic, possibly focusing on mild Cushing's Disease and well-characterized NNH/pCS patients.

AIM: To evaluate frequency of heart failure syndrome in patients with endogenous hypercortisolism and to establish relationship between effective treatment for hypercortisolism and regression of heart failure with particular emphasis on the observation of NT-proBNP and ST2 levels. MATERIALS AND METHODS: 56 patients with endogenous hypercortisolism (45 female, mean age 47 years [36; 55] hospitalized with endogenous hypercortisolism to National Medical Research Center for Endocrinology were enrolled in the study. All patients underwent comprehensive clinical investigation including expert echocardiography with speckle tracking and evaluation of NT-proBNP and ST2 cardiac biomarkers at baseline and 6 months after surgical treatment. RESULTS: According to clinical data and elevated biomarkers of cardiac stress 28 out of 56 patients (50%) at baseline met the criteria for heart failure. 20 patients were included in the final analysis. Follow-up investigation with focus on changes in NT-proBNP and ST2 levels demonstrated that surgical correction of endogenous hypercortisolism resulted in resolution of heart failure syndrome in 11 patients (55%). CONCLUSION: These preliminary data suggest that signs and symptoms of heart failure are observed in patients with endogenous hypercortisolism in about half the cases. Surgical correction results in resolution of heart failure in approximately two thirds of the cases. Prospective evaluation NT-proBNP and ST2 levels may provide important diagnostic and prognostic information in patients with endogenous hypercortisolism.

Only a few subacute thyroiditis (SAT) cases secondary to hypocortisolemia developed after successfully treating Cushing's disease (CD) have been reported. In this report, we present an SAT case, which developed immediately after discontinuation of steroid treatment for hypocortisolemia after the successful treatment of CD. A 54-year-old female patient who had recently been diagnosed with type 2 diabetes mellitus was admitted to our center with complaints of proximal myopathy and obesity. Serum cortisol did not suppress adequately after the 1 mg dexamethasone suppression test. Pituitary MRI of the patient with increased basal plasma ACTH level revealed a 6 x 5 mm right-sided adenoma. After successful surgical treatment, the patient was given ten months of steroid therapy due to a suppressed corticotroph axis. Shortly after the steroid treatment was discontinued, the patient was admitted with neck pain, fever, and thyrotoxicosis. The patient was diagnosed with SAT, and methylprednisolone treatment was started again. The underlying pathophysiological mechanisms in SAT cases that develop after the treatment of CD can only be speculated. One possible mechanism could be that the glucocorticoid deficiency develops after effective treatment of hypercortisolism alters the immunological responses or generates self-reactive cells and prepares an appropriate environment for the thyrolytic process.
RESUMEN
Hypertension is one of the leading causes of premature death in humans and exhibits a complex aetiology including environmental and genetic factors. Mutations within the glucocorticoid receptor (GR) can cause glucocorticoid resistance, which is characterized by several clinical features like hypercortisolism, hypokalaemia, adrenal hyperplasia and hypertension. Altered glucocorticoid receptor signalling further affects sodium and potassium homeostasis as well as blood pressure regulation and cell proliferation and differentiation that influence organ development and function. In salt-sensitive hypertension, excessive renal salt transport and sympathetic nervous system stimulation may occur simultaneously, and, thus, both the mineralocorticoid receptor (MR) and the GR-signalling may be implicated or even act interdependently. This review focuses on identified GR mutations in human primary generalized glucocorticoid resistance (PGGR) patients and their related clinical phenotype with specific emphasis on adrenal gland hyperplasia and hypertension. We compare these findings to mouse and rat mutants harbouring genetically engineered mutations to further dissect the cause and/or the consequence of clinical features which are common or different.

OBJECTIVES: Cushing's disease (CD) is most common endogenous Cushing's syndrome. This study aimed to assess iron alternations in deep grey matter in CD. DESIGN: A cross-sectional study was performed. PATIENTS: In this study, 48 active CD patients, 39 remitted CD patients and 52 healthy control (HC) subjects underwent magnetic resonance imaging. MEASUREMENTS: Quantitative susceptibility mapping (QSM). RESULTS: Decreased susceptibility values were found in the bilateral putamen, caudate, red nucleus, subthalamic nucleus and pulvinar nuclei of the thalamus (TL-PLV) in active and remitted patients with CD compared with HCs. Interestingly, in remitted patients with CD, altered susceptibility values were significantly correlated with altered brain volumes in TL-PLV, while TL-PLV may play an essential role as a general regulatory hub for adaptive and flexible cognition. CONCLUSION: Chronic exposure to hypercortisolism may be related to iron distribution and significantly correlated with altered brain volumes and clinical features in patients with CD.

OBJECTIVE: Ectopic Cushing's syndrome (ECS) induced by medullary thyroid cancer (MTC) is rare, and data on clinical characteristics, treatment and outcome are limited. DESIGN: Retrospective cohort study in three German and one Swiss referral centres. PATIENTS: Eleven patients with MTC and occurrence of ECS and 22 matched MTC patients without ECS were included. MEASUREMENTS: The primary endpoint of this study was the overall survival (OS) in MTC patients with ECS versus 1:2 matched MTC patients without ECS. RESULTS: The median age at diagnosis of ECS was 59 years (range: 35-81) and the median time between initial diagnosis of MTC and diagnosis of ECS was 29 months (range: 0-193). Median serum morning cortisol was 49 µg/dl (range: 17-141, normal range: 6.2-18). Eight (73%) patients received treatment for ECS. Treatment of ECS consisted of bilateral adrenalectomy (BADX) in four (36%) patients and adrenostatic treatment in eight (73%) patients. One patient received treatment with multityrosine kinase inhibitor (MKI) to control hypercortisolism. All patients experienced complete resolution of symptoms of Cushing's syndrome and biochemical control of hypercortisolism. Patients with ECS showed a shorter median OS of 87 months (95% confidence interval [95% CI]: 64-111) than matched controls (190 months, 95% CI: 95-285). Of the nine deaths, four were related to progressive disease (PD). Four patients showed PD as well as complications and comorbidities of hypercortisolism before death. CONCLUSION: This study shows that ECS occurs in advanced stage MTC and is associated with a poor prognosis. Adrenostatic treatment and BADX were effective systemic treatment options in patients with MTC and ECS to control their hypercortisolism. MKI treatment achieved complete remission of hypercortisolism and sustained tumour control in one treated case.

Patients with endogenous or exogenous glucocorticoid (GC) excess exhibit a range of side effects, including an increased risk of infections. Via both mechanism, immune impairments and cardiometabolic concomitant diseases, patients with GC excess could be at increased risk for COVID-19. The impact on incidence and outcome of a SARS-CoV-2 infection in this population are not yet completely clear. This review aims to compile the data available to date and to discuss the existing literature on this topic. Further we highlight potential effects of SARS-CoV-2 on the hypothalamic-pituitary-adrenal axis as well as the influence of endogenous or exogenous GC excess on SARS-CoV-2 mRNA vaccination. There is growing evidence suggesting an increased risk of infection and severe outcome in patients with high-dose GC therapy after contracting SARS-CoV-2. The few data and case reports on patients with endogenous GC excess and SARS-CoV-2 infection point in a similar direction: chronic GC excess seems to be associated with an unfavorable course of COVID-19. Whether this is mainly a primary immune-mediated effect, or also triggered by the many GC-associated comorbidities in this population, is not yet fully understood. Patients with endogenous or exogenous GC excess should be considered as a vulnerable group during the SARS-CoV-2 pandemic. Regardless of the cause, vaccination and consistent surveillance and control of associated comorbidities are recommended.

BACKGROUND: There is only one documented case of intracranial hypertension (IH) and empty sella from cortisol-producing adrenal adenoma so far. And IH and empty sella caused by long-term exogenous hypercortisolism has never been reported before. The purpose of this case report is to alert clinicians to glucocorticoid-induced IH. CASE PRESENTATION: We present retrospectively a 50-year-old woman with cortisol-secreting adrenal adenoma, who progressed to intractable intracranial hypertension and a markedly expanded empty sella due to improper treatment. In 2011, the patient presented with hypertension, lack of cortisol circadian rhythm, low ACTH, a left adrenal adenoma and a partial empty sella, but did not receive low-dose dexamethasone suppression test (LDDST) and 24-h urinary cortisol. In 2014, she exhibited truncal obesity, raised cortisol, LDDST non-suppression, high urinary free cortisol and low ACTH, proving her cortisol-producing adrenal adenoma. She was simultaneously diagnosed with unexplained IH because of papilledema and elevated intracranial pressure, and her partial empty sella changed to a complete empty sella. In 2015, she underwent adrenal adenoma resection. From 2015 to 2018, she kept taking dexamethasone at least 2 mg daily without her doctors' consent. During this period, she developed transient cerebrospinal fluid rhinorrhea, and her empty sella further worsened. After switching to low dose hydrocortisone, her papilledema disappeared completely, but optic atrophy has become irreversible. CONCLUSIONS: The patient seems to be just an extreme case, but it may reveal and illustrate a general phenomenon: Both cortisol-producing adrenal adenoma and long-term exogenous hypercortisolism could cause varying degrees of elevated intracranial pressure and empty sella. Clinicians should remain vigilant for this phenomenon in patients with cortisol-producing adrenal adenoma or excessive and prolonged steroid usage and give them corresponding examinations to identify this complication.
