Abstract
We recently reported the use of optical imaging technology to quantify facial plethora in endogenous Cushing syndrome (CS). In the present study, we studied a larger cohort of patients with Cushing disease (CD) and examined water content fraction as well as blood volume fraction as bio-optic markers for determining the efficacy of this methodology as a predictor of lasting remission after surgery for CS. We imaged 49 patients before and after transsphenoidal surgery (TSS) for Cushing disease (CD); 22 patients were also seen at 3-6 months, and 13 patients 12 months post-operatively. On all patients, we used multi-spectral imaging (MSI) to evaluate hemodynamic distributions as well as water content at a specific area of the face. We found a decrease in blood volume fraction after vs. before surgical treatment in the tested facial area in 37 of the 40 patients, as determined with biochemical markers (p<0.001). All patients that were followed up for up to 12 months showed the same decrease from preoperative values and they remained in remission from CD. We conclude that MSI can be used for the evaluation of remission from CD, at least in the immediate post-operative period and up to one year after surgery. The use of this technology can supplement biochemical and other testing for the evaluation of the various treatment modalities available for patients with CD.

Abstract
BACKGROUND Cushing disease (CD) represents the principal cause of endogenous hypercortisolism. The first-line therapy of CD is surgical removal of the ACTH-secreting pituitary adenoma, which is generally followed by adrenal insufficiency (AI). OBJECTIVE To analyze the recovery of AI in patients with CD after pituitary surgery in relation with recurrence and persistent remission of CD. PATIENTS AND METHODS We performed a retrospective analysis of patients with CD who met the following inclusion criteria: adult age, presence of AI 2 months after the surgical intervention, and a minimum follow-up of 3 years after the surgical intervention. RESULTS Sixty-one patients were followed for a median of 6 years. Ten (16.4%) patients recurred during follow-up. The patients who restored adrenal function did so after a median time of 19 months, with a significantly shorter time in the recurrence group (12.5 vs. 25 months, p = 0.008). All 10 patients who recurred recovered their adrenal function within 22 months. The recovery rate of AI in the persistent remission group was 37.3% (19/51) at 3 years and 55.8% (24/43) at 5 years. In all patients the duration of AI was negatively associated with disease recurrence. CONCLUSION The duration of postsurgical AI in patients with recurrent CD is significantly shorter than that in patients with persistently remitted CD, and this parameter may be a useful predictor of recurrence. Patients showing a normal pituitary-adrenal axis within 2 years after surgery should be strictly monitored as they are at higher risk of disease relapse.

Abstract
BACKGROUND The results of trans-sphenoidal surgery (TSS) in Cushing's disease (CD) vary widely depending upon patient characteristics as well as surgical experience. Patients in India are often referred late to referral centers. We studied the rates of remission and endocrine deficiencies after TSS in patients with CD presenting to a referral hospital in India. METHODS Sixty consecutive patients (45 females, median age 24.5 years) who underwent TSS between 2000 and 2015 were studied. The median (range) duration of follow-up was 40 (3-138) months. Initial and long-term remission and relapse rates and pituitary hypofunction post-TSS were evaluated. RESULTS Eighteen (30%) patients harbored macroadenomas. Twenty-eight (47%) patients achieved remission in the immediate post-operative period (8 AM serum cortisol < 140 nmol/l), while a higher remission rate was noted at 6 months (39/54 patients, 72%). At 1 year 70% patients and at final follow-up [median duration 40 (range 3-138) months], 58% of patients were in remission. No pre- or post-surgical variables were consistently associated with remission, except for the 8-AM serum cortisol level on the fifth day after surgery. Seven (18%) patients relapsed on follow-up, including five patients who had fifth post-operative day 8 AM serum cortisol < 140 nmol/l. Twelve (25%) patients newly developed hypothyroidism and one (1.6%) patient developed amenorrhoea after TSS. CONCLUSION Remission rate at 6 months was higher than immediately after TSS. A significant proportion of patients relapsed, thus necessitating life-long follow-up. New-onset hypothyroidism was frequent after TSS.

Abstract
BACKGROUND There are no reliable predictive models for recurrence after transsphenoidal surgery (TSS) for Cushing's disease (CD). OBJECTIVES This study aimed to develop machine learning (ML)-based predictive models for CD recurrence after initial TSS and to evaluate their performance. METHOD A total of 354 CD patients were included in this retrospective, supervised learning, data mining study. Predictive models for recurrence were developed according to 17 variables using 7 algorithms. Models were evaluated based on the area under the receiver operating characteristic curve (AUC). RESULTS All patients were followed up for over 12 months (mean ± SD 43.80 ± 35.61). The recurrence rate was 13.0%. Age (p < 0.001), postoperative morning serum cortisol nadir (p = 0.002), and postoperative (p < 0.001) and preoperative (p = 0.04) morning adrenocorticotropin (ACTH) level were significantly related to recurrence. AUCs of the 7 models ranged from 0.608 to 0.781. The best performance (AUC = 0.781, 95% CI 0.706, 0.856) appeared when 8 variables were introduced to the random forest (RF) algorithm, which was much better than that of logistic regression (AUC = 0.684, p = 0.008) and that of using only postoperative morning serum cortisol (AUC = 0.635, p < 0.001). According to the feature selection algorithms, the top 3 predictors were age, postoperative serum cortisol, and postoperative ACTH. CONCLUSIONS Using ML-based models for prediction of the recurrence after initial TSS for CD is feasible, and RF performs best. The performance of most of ML-based models was significantly better than that of some conventional models.

Abstract
RATIONALE Knosp grade 4 adrenocorticotropic hormone (ACTH)-secreting pituitary adenoma is a rare cause of Cushing disease. After the 1st surgery, the remission rate among these patients is extremely low. PATIENT CONCERNS We presented a case of a 33-year-old female with classical Cushingoid symptoms. Further investigations revealed ATCH-dependent hypercortisolemia, as well as a Knosp grade 4 pituitary macroadenoma. DIAGNOSIS Cushing disease, caused by a Knosp grade 4 pituitary macroadenoma. INTERVENTIONS The patient underwent endoscopic endonasal transsphenoidal surgery with the assistance of intraoperative transsphenoidal Doppler and image-guidance devices. OUTCOMES Pathologic examinations confirmed that the lesion was an ACTH-secreting pituitary adenoma. The patient was in biochemical remission after surgery. Her postoperative magnetic resonance imaging showed gross-total tumor resection. There was no evidence of recurrence during the 1-year follow-up. LESSONS With intraoperative Doppler and image-guidance, gross-total resection and biochemical remission can be achieved in Cushing disease when the internal carotid artery is completely encased by the pituitary adenoma.

Abstract
PURPOSE Systematic review and meta-analysis comparing endoscopic and microscopic transsphenoidal surgery for Cushing's disease regarding surgical outcomes (remission, recurrence, and mortality) and complication rates. To stratify the results by tumor size. METHODS Nine electronic databases were searched in February 2017 to identify potentially relevant articles. Cohort studies assessing surgical outcomes or complication rates after endoscopic or microscopic transsphenoidal surgery for Cushing's disease were eligible. Pooled proportions were reported including 95% confidence intervals. RESULTS We included 97 articles with 6695 patients in total (5711 microscopically and 984 endoscopically operated). Overall, remission was achieved in 5177 patients (80%), with no clear difference between both techniques. Recurrence was around 10% and short term mortality < 0.5% for both techniques. Cerebrospinal fluid leak occurred more often in endoscopic surgery (12.9 vs. 4.0%), whereas transient diabetes insipidus occurred less often (11.3 vs. 21.7%). For microadenomas, results were comparable between both techniques. For macroadenomas, the percentage of patients in remission was higher after endoscopic surgery (76.3 vs. 59.9%), and the percentage recurrence lower after endoscopic surgery (1.5 vs. 17.0%). CONCLUSIONS Endoscopic surgery for patients with Cushing's disease reaches comparable results for microadenomas, and probably better results for macroadenomas than microscopic surgery. This is present despite the presumed learning curve of the newer endoscopic technique, although confounding cannot be excluded. Based on this study, endoscopic surgery may thus be considered the current standard of care. Microscopic surgery can be used based on neurosurgeon's preference. Endocrinologists and neurosurgeons in pituitary centers performing the microscopic technique should at least consider referring Cushing's disease patients with a macroadenoma.

Abstract
BACKGROUND To define the symptoms, signs and treatment outcomes in a population of older patients with Cushing's disease (CD). METHODS We analysed the clinical presentation and treatment outcomes in 45 CD patients older than 60 years, in comparison with 90 CD patients younger than 60, and a control group of 45 older patients with nonfunctioning pituitary adenomas. We reviewed preoperative clinical characteristics, medical comorbidities, imaging findings and endocrine testing as well as surgical and endocrine outcomes. RESULTS Older CD patients had significantly lower body mass index (BMI) (P = 0.031), were more likely to have muscle wasting (P = 0.006) and women were less likely to have hirsutism (P = 0.033). Older patients with CD had more medical comorbidities than younger patients, which correlated with a higher ASA grade (P < 0.001), but the surgical complication rates were similar in both groups. Surgical remission was achieved in 38/45 (84.4%) older patients and 78/90 (86.7%) younger patients (P = NS). Recurrent disease was more frequent in younger patients (19.2%) in comparison with older patients (2.6%, P = 0.019). CONCLUSIONS Older patients with CD appear to have a distinct phenotype with a more catabolic picture, including a lower BMI and greater prevalence of muscle wasting. Surgical outcomes are similar without a significant age-related increase in complications.

Abstract
PURPOSE Surgical experience is considered paramount for excellent outcome of transsphenoidal surgery (TSS). However, objective data demonstrating the surgical success in relation to the experience of pituitary surgery units or individual experience of pituitary surgeons is sparse. METHODS Based on literature data, we have investigated the influence of experience with TSS for pituitary adenomas on endocrinological remission rates and on operative complications. The surgical experience was assessed by calculating the number of transsphenoidal operations per year. RESULTS For TSS of microprolactinomas, mean remission rates were 77% in centers with < 2 operations per year for microprolactinomas, 82% with 2-4 operations, 84% with 4-6 operations, and 91% with > 6 operations. A yearly experience with more than 10 initial operations for Cushing's disease (CD) warrants a remission rate exceeding 70%. Remission rates in CD exceeding 86% have only been reported for single surgeon series. Extraordinarily high complication rates were found in some series with < 25 yearly total operations for pituitary adenomas. Major vascular complications were less than 2% and revision rates for rhinorrhea usually < 2.5% in centers performing > 25 transsphenoidal operations per year. CONCLUSIONS We conclude that a center with experience of > 25 transsphenoidal operations for pituitary adenomas per year provides a high likelihood of safe TSS. Surgery for CD requires a particularly high level of practice to guarantee excellent remission rates. The endocrinologist has the unique opportunity to audit the surgical success by hormone measurement and to refer patients to neurosurgeons with proven excellence.

Abstract
Transsphenoidal surgery is the main treatment of patients with adrenocorticotropic hormone (ACTH)-secreting pituitary adenomas. Although biochemical remission occurs in most patients undergoing operations at specialized centers, the recurrence risk is significant. Visualization of microadenomas on preoperative imaging and confirmation of ACTH-positive adenomas have been associated with higher remission rates. Low cortisol levels in the first 2 weeks postoperatively have been associated with durable remission; however, recurrence cannot be excluded by any cortisol threshold. The decision to perform a pituitary reoperation is based on this parameter; the protocols are institution specific. Patients with Cushing's disease warrant lifelong endocrinologic surveillance.

Abstract
CONTEXT Achievement of hypocortisolemia following transsphenoidal surgery (TSS) for Cushing's disease (CD) is associated with successful adenoma resection. However, up to one-third of these patients recur. OBJECTIVE We assessed whether delay in reaching post-operative cortisol nadir may delineate patients at risk of recurrence for CD following TSS. METHODS A retrospective review of 257 patients who received 291 TSS procedures for CD at NIH, between 2003 and 2016. Early biochemical remission (serum cortisol nadir <5 μg/dL) was confirmed with endocrinological and clinical follow-up. Recurrence was detected by laboratory testing, clinical stigmata or medication dependence during a median follow-up of 11 months. RESULTS Of the 268 unique admissions, remission was recorded in 241 instances. Recurrence was observed in 9% of these cases with cortisol nadir ≤5 μg/dL and 6% of cases with cortisol nadir ≤2 μg/dL. The timing of hypocortisolemia was critical in detecting late recurrences. Morning POD-1 cortisol <3.3 μg/dL was 100% sensitive in predicting durable remission and morning POD-3 cortisol ≥18.5 μg/dL was 98.6% specific in predicting remote recurrence. AUROC analysis revealed that hypocortisolemia ≤5 µg/dL before 15 h (post-operative) had 95% sensitivity and an NPV of 0.98 for durable remission. Serum cortisol level ≤2 µg/dL, when achieved before 21 h, improved sensitivity to 100%. CONCLUSIONS In our cohort, early, profound hypocortisolemia could be used as a clinical prediction tool for durable remission. Achievement of hypocortisolemia ≤2 µg/dL before 21 post-operative hours appeared to accurately predict durable remission in the intermediate term.

Abstract
RATIONALE Adrenal myelolipomas are rare benign tumors, composed of a variable mixture of mature adipose tissue and hematopoietic tissue. These tumors are frequently detected incidentally and are usually asymptomatic, and hormonally inactive. PATIENT CONCERNS During a routine health checkup, a 52-year-old man was found to have a tumor on the bilateral adrenal glands. Abdominal computed tomography revealed a well-defined, heterogeneously enhanced bilateral adrenal mass, suggesting a myelolipoma. DIAGNOSES The hormonal evaluation revealed adrenocorticotropic hormone (ACTH) dependent Cushing syndrome. INTERVENTIONS The patient underwent left adrenalectomy, and transsphenoidal resection of a pituitary mass. The final diagnosis was adrenal myelolipoma associated with Cushing disease. OUTCOMES Growth of right adrenal myelolipoma was detected during the 7-year follow-up. There were enhancing pituitary lesions in repeat magnetic resonance imaging of the sellar region, which implies persistent or recurrent pituitary adenoma. This case reinforces relationship between Cushing disease and adrenal myelolipoma. LESSONS To the best of our knowledge, this is the first reported pathologically confirmed bilateral adrenal myelolipoma associated with Cushing disease. This report supports the idea that ACTH is associated with the development of adrenal myelolipoma.

Abstract
PURPOSE Patients affected by Cushing's disease often have important comorbidities directly linked to hypercortisolism that might enhance the operative risk. We report the safety of transsphenoidal surgery in patients affected by Cushing's disease as compared with patients with nonfunctioning pituitary adenoma. METHODS We have retrospectively analyzed 142 patients with Cushing's disease and 299 patients with nonfunctioning pituitary adenoma who underwent transsphenoidal surgery performed by a single experienced neurosurgeon between September 2007 and December 2014. For all of them, an intraoperative computerized anesthetic record for the automatic storage of data was available. RESULTS The intraoperative vital parameters and the frequency of drugs administered during anesthesia were comparable between Cushing's disease and nonfunctioning pituitary adenoma groups. The duration of surgery was similar between the two groups (41.2 ± 11.8 vs. 42.9 ± 15.6 min), while the duration of anesthesia was slightly shorter in Cushing's disease patients (97.6 ± 18.1 min) than in nonfunctioning pituitary adenoma patients (101.6 ± 20.6 min, p = 0.04). The total perioperative mortality rate was 0.2% (0% in Cushing's disease vs. 0.3% in nonfunctioning pituitary adenoma). Cushing's disease patients had surgical and medical complication rates of 3.5% each, not different from those occurring in nonfunctioning pituitary adenoma. The postoperative incidence of diabetes insipidus (10.6%) and isolated hyponatremia (10.6%) in Cushing's disease patients was significantly higher than in nonfunctioning pituitary adenoma patients (4.4 and 4.1%; p = 0.02 and p = 0.01, respectively). CONCLUSIONS In a large series of unselected and consecutive patients with Cushing's disease, transsphenoidal surgery performed by one dedicated experienced neurosurgeon had a reasonably low risk of complications. In particular, despite the higher burden of comorbidities typically associated with hypercortisolism, medical complications are rare and no more frequent than in patients with nonfunctioning pituitary adenoma.

Abstract
CONTEXT Cushing disease (CD) due to adrenocorticotropic hormone-secreting pituitary tumors can be a management challenge. OBJECTIVE To better understand the outcomes of stereotactic radiosurgery (SRS) for CD and define its role in management. DESIGN International, multicenter, retrospective cohort analysis. SETTING Ten medical centers participating in the International Gamma Knife Research Foundation. PATIENTS Patients with CD with >6 months endocrine follow-up. INTERVENTION SRS using Gamma Knife radiosurgery. MAIN OUTCOME MEASURES The primary outcome was control of hypercortisolism (defined as normalization of free urinary cortisol). Radiologic response and adverse radiation effects (AREs) were recorded. RESULTS In total, 278 patients met inclusion criteria, with a mean follow-up of 5.6 years (0.5 to 20.5 years). Twenty-two patients received SRS as a primary treatment of CD. Mean margin dose was 23.7 Gy. Cumulative initial control of hypercortisolism was 80% at 10 years. Mean time to cortisol normalization was 14.5 months. Recurrences occurred in 18% with initial cortisol normalization. Overall, the rate of durable control of hypercortisolism was 64% at 10 years and 68% among patients who received SRS as a primary treatment. AREs included hypopituitarism (25%) and cranial neuropathy (3%). Visual deficits were related to treatment of tumor within the suprasellar cistern (P = 0.01), whereas both visual (P < 0.0001) and nonvisual cranial neuropathy (P = 0.02) were related to prior pituitary irradiation. CONCLUSIONS SRS for CD is well tolerated and frequently results in control of hypercortisolism. However, recurrences can occur. SRS should be considered for patients with persistent hypercortisolism after pituitary surgery and as a primary treatment in those unfit for surgery. Long-term endocrine follow-up is essential after SRS.

INTRODUCTION With the goal of generate uniform criteria among centers dealing with pituitary tumors and to enhance patient care, the Pituitary Society decided to generate criteria for developing Pituitary Tumors Centers of Excellence (PTCOE). METHODS To develop that task, a group of ten experts served as a Task Force and through two years of iterative work an initial draft was elaborated. This draft was discussed, modified and finally approved by the Board of Directors of the Pituitary Society. Such document was presented and debated at a specific session of the Congress of the Pituitary Society, Orlando 2017, and suggestions were incorporated. Finally the document was distributed to a large group of global experts that introduced further modifications with final endorsement. RESULTS After five years of iterative work a document with the ideal criteria for a PTCOE is presented. CONCLUSIONS Acknowledging that very few centers in the world, if any, likely fulfill the requirements here presented, the document may be a tool to guide improvements of care delivery to patients with pituitary disorders. All these criteria must be accommodated to the regulations and organization of Health of a given country.

Abstract
CONTEXT Transsphenoidal surgery (TSS) to resect a pituitary adenoma is considered first-line treatment for patients with Cushing's disease (CD). Early, post-operative remission rates >80% are expected for patients with a microadenoma (≤ 10 mm) visible on magnetic resonance (MR) imaging. OBJECTIVE To report surgical outcomes and predictors of remission in a specialist center for patients with CD. PATIENTS AND METHODS Clinical data was obtained from a prospective CD database in addition to review of all electronic medical, laboratory and surgical patient records. Patients who underwent their first TSS by one neurosurgeon between 2004 and 2013, and had a minimum 1 year follow up, were evaluated. RESULTS One hundred and one consecutive patients with CD (73F, 28M) underwent TSS. Median (range) age and follow-up were 47 (15-87) and 4.33 (1-9.8) years, respectively. At surgery, 74 (73.2%) patients had a microadenoma, 27 a macroadenoma; six of the latter patients had a planned, subtotal resection to control neurological signs due to mass effect. Initial remission rates were: microadenoma, 89% (66/74); macroadenoma, 63% (17/27); and 81% (17/21) in those macroadenomas where complete surgical removal was anticipated. Initial non-remission occurred in 18 patients, ten macro- and eight microadenoma; six of 18 had residual disease on most recent follow up. Six (2 macro, 4 micro) of the 83 patients with initial remission have had late (>12 months) recurrence of hypercortisolism that required either repeat TSS or adjunctive therapy, three of whom have persistent hypercortisolism. Macroadenoma (p = 0.003) and tumor invasion beyond the pituitary and sella (p < 0.001) were associated with failure to obtain remission with the initial TSS and greater likelihood of late recurrence. Patients in whom no lesion was seen on neuroimaging had rates of initial remission (21/25 or 84%) and a similar late recurrence rate of 4% (1/25) in comparison with those with MR-visible microadenomas (3/49, or 6%). CONCLUSIONS A team-based approach, in a specialized pituitary center, can lead to initial and durable, long-term remission in patients with CD. The presence of a macroadenoma and tumor extension beyond the pituitary and sella were predictive of initial non-remission as well as risk of late recurrence.

Abstract
PURPOSE Follow-up guidelines are needed to assess quality of care and to ensure best long-term outcomes for patients with Cushing's disease (CD). The purpose of this study was to assess agreement by experts on recommended follow-up intervals for CD patients at different phases in their treatment course. METHODS The RAND/UCLA modified Delphi process was used to assess expert consensus. Eleven clinicians who regularly manage CD patients rated 79 hypothetical patient scenarios before and after ("second round") an in-person panel discussion to clarify definitions. Scenarios described CD patients at various time points after treatment. For each scenario, panelists recommended follow-up intervals in weeks. Panel consensus was assigned as follows: "agreement" if no more than two responses were outside a 2 week window around the median response; "disagreement" if more than two responses were outside a 2 week window around the median response. Recommendations were developed based on second round results. RESULTS Panel agreement was 65.9% before and 88.6% after the in-person discussion. The panel recommended follow-up within 8 weeks for patients in remission on glucocorticoid replacement and within 1 year of surgery; within 4 weeks for patients with uncontrolled persistent or recurrent disease; within 8-24 weeks in post-radiotherapy patients controlled on medical therapy; and within 24 weeks in asymptomatic patients with stable plasma ACTH concentrations after bilateral adrenalectomy. CONCLUSIONS With a high level of consensus using the Delphi process, panelists recommended regular follow-up in most patient scenarios for this chronic condition. These recommendations may be useful for assessment of CD care both in research and clinical practice.

Abstract
CONTEXT Somatic mutations in the ubiquitin-specific protease 8 (USP8) gene have been recently identified as the most common genetic alteration in patients with Cushing disease (CD). However, the frequency of these mutations in the pediatric population has not been extensively assessed. OBJECTIVE We investigated the status of the USP8 gene at the somatic level in a cohort of pediatric patients with corticotroph adenomas. DESIGN AND METHODS The USP8 gene was fully sequenced in both germline and tumor DNA samples from 42 pediatric patients with CD. Clinical, biochemical, and imaging data were compared between patients with and without somatic USP8 mutations. RESULTS Five different USP8 mutations (three missense, one frameshift, and one in-frame deletion) were identified in 13 patients (31%), all of them located in exon 14 at the previously described mutational hotspot, affecting the 14-3-3 binding motif of the protein. Patients with somatic mutations were older at disease presentation [mean 5.1 ± 2.1 standard deviation (SD) vs 13.1 ± 3.6 years, P = 0.03]. Levels of urinary free cortisol, midnight serum cortisol, and adrenocorticotropic hormone, as well as tumor size and frequency of invasion of the cavernous sinus, were not significantly different between the two groups. However, patients harboring somatic USP8 mutations had a higher likelihood of recurrence compared with patients without mutations (46.2% vs 10.3%, P = 0.009). CONCLUSION Somatic USP8 gene mutations are a common cause of pediatric CD. Patients harboring a somatic mutation had a higher likelihood of tumor recurrence, highlighting the potential importance of this molecular defect for the disease prognosis and the development of targeted therapeutic options.

Abstract
CONTEXT Perioperative increases in adrenocorticotropic hormone (ACTH) and cortisol mimic results of corticotropin-releasing hormone (CRH) stimulation testing. This phenomenon may help identify patients with residual adenoma after transsphenoidal surgery (TSS) for Cushing disease (CD). OBJECTIVE To predict nonremission after TSS for CD. DESIGN Retrospective case-control study of patients treated at a single center from December 2003 until July 2016. Early and medium-term remission were assessed at 10 days and 11 months. PATIENTS AND SETTING Two hundred and ninety-one consecutive TSS cases from 257 patients with biochemical evidence of CD seen at a clinical center. INTERVENTIONS Normalized early postoperative values (NEPVs) for cortisol and ACTH were calculated as immediate postoperative cortisol or ACTH levels minus preoperative post-CRH-stimulation test levels. MAIN OUTCOME MEASURES Prediction of early nonremission was evaluated using logistic regression. Prediction of medium-term remission was assessed using Cox regression. Predictive ability was quantified by area under the receiver operating characteristic curve (AUROC). RESULTS NEPVs for cortisol and ACTH predicted early nonremission [adjusted odds ratio (OR): 1.1; 95% confidence interval (CI): 1.0, 1.1; P = 0.016 and adjusted OR: 1.0; 95% CI: 1.0, 1.0; P = 0.048, respectively]. AUROC for NEPV of cortisol was 0.78 (95% CI: 0.61, 0.95); for NEPV of ACTH, it was 0.80 (95% CI: 0.61, 0.98). NEPVs for cortisol and ACTH predicted medium-term nonremission [hazard ratio (HR): 1.1; 95% CI: 1.0, 1.1; P = 0.023 and HR: 1.0; 95% CI: 1.0, 1.0; P = 0.025, respectively]. CONCLUSIONS NEPVs for cortisol and ACTH predicted nonremission after TSS for CD.

Abstract
Successful treatment of Cushing syndrome causes transient or permanent adrenal insufficiency deriving from endogenous hypercortisolism-induced hypothalamus-pituitary-adrenal-axis suppression. We analyzed pre-treatment factors potentially affecting the duration of adrenal insufficiency. We conducted a retrospective analysis on patients successfully treated for Cushing disease (15 patients) who underwent transsphenoidal surgery, and nonmalignant primary adrenal Cushing syndrome (31 patients) who underwent unilateral adrenalectomy, divided into patients with overt primary adrenal Cushing syndrome (14 patients) and subclinical primary adrenal Cushing syndrome (17 patients). Epidemiological data, medical history, and hormonal parameters depending on the etiology of hypercortisolism were collected and compared to the duration of adrenal insufficiency. The median duration of follow-up after surgery for Cushing disease and primary adrenal Cushing syndrome was 70 and 48 months, respectively. In the Cushing disease group, the median duration of adrenal insufficiency after transsphenoidal surgery was 15 months: younger age at diagnosis and longer duration of signs and symptoms of hypercortisolism before diagnosis and surgery were associated with longer duration of adrenal insufficiency. The median duration of adrenal insufficiency was 6 months for subclinical primary adrenal Cushing syndrome and 18.5 months for overt primary adrenal Cushing syndrome. The biochemical severity of hypercortisolism, the grade of hypothalamus-pituitary-adrenal-axis suppression, and treatment with ketoconazole before surgery accounted for longer duration of adrenal insufficiency. In patients with Cushing disease, younger age and delayed diagnosis and treatment predict longer need for glucocorticoid replacement therapy after successful transsphenoidal surgery. In patients with primary adrenal Cushing syndrome, the severity of hypercortisolism plays a primary role in influencing the duration of adrenal insufficiency after unilateral adrenalectomy.

Abstract
INTRODUCTION The 2012 British Association of Endocrine and Thyroid Surgeons audit report showed that only 86 of 1359 patients who underwent adrenalectomy had a bilateral operation; thus the experience with this procedure remains limited. METHODS Retrospective review of patients undergoing bilateral adrenalectomy in a tertiary referral centre. RESULTS Between November 2005 and January 2016, bilateral adrenalectomy was performed in 23 patients (6 male, 17 female, age 43 ± 4 years) diagnosed with Cushing's disease (n = 13), hereditary phaeochromocytomas (n = 6), adrenocortical cancer (n = 2), colorectal metastatic disease (n = 1) and adrenocortical adenomas (n = 1). A laparoscopic transperitoneal approach was used in 17 patients, with one conversion to open. Three patients had open adrenalectomies for adrenocortical cancer and for simultaneous phaeochromocytomas and pancreatic neuroendocrine tumours in a patient with Von Hippel-Lindau syndrome. Three patients with Cushing's had a bilateral retroperitoneoscopic operation. The mean operating time was 195 ± 16 minutes for laparoscopic operations (n = 16), 243 ± 44 minutes for open adrenalectomies (n = 4) and 151 ± 12 minutes for retroperitoneal operations. It was significantly shorter for Cushing's disease than for phaeochromocytomas (162 ± 8 vs. 257 ± 39 minutes, P < 0.01). Median length of hospital stay was 5 days. Postoperative complications (Clavien-Dindo classification) included one chest infection (level 2), one postoperative haemorrhage and two chest drains for pneumothorax (level 3), two postoperative cardiac arrests (level 4) and one late cancer death from complications related to uncontrolled hypercortisolism (level 5). DISCUSSION Synchronous bilateral adrenalectomy remains an infrequent operation. The laparoscopic approach is feasible in the majority of patients. It is likely that the retroperitoneoscopic adrenalectomy will become the standard approach for bilateral operations.

Abstract
CONTEXT Inflammation contributes to the development of metabolic and cardiovascular disease. Cushing's disease (CD), a state of chronic glucocorticoid (GC) excess characterized by visceral obesity and insulin resistance, may be associated with increased systemic inflammation. Cardiovascular mortality in CD remains elevated even after successful remission. It is unclear whether a chronic low-grade inflammatory state persists even after remission of CD, which may account for the increased CVD mortality. PURPOSE (1) To assess circulating proinflammatory cytokines in patients with active CD and BMI-matched controls; (2) to prospectively follow plasma cytokine concentrations in patients with CD before and after surgical remission; and (3) to assess whether plasma cytokine concentrations correlate with adipose tissue distribution and ectopic lipid content in liver and muscle. METHODS Plasma cytokines from prospectively enrolled patients with CD (N = 31) were quantified during active disease (v1) vs controls (N = 18) and 19·5 ± 12·9 months after surgical remission (v2). Fasting plasma IL-6, IL-1β, TNF-α, IL-8, IL-17 and IL-10 were quantified using a multiplex assay. Total and regional fat masses were measured by whole-body MRI. RESULTS Circulating IL-6 and IL-1β were elevated in patients with active CD vs controls (P < 0·05) and remained elevated in CD after surgical remission, despite decreases in BMI (P < 0·001), HOMA-IR (P < 0·001), and visceral, hepatic and intermuscular fat (P < 0·001, <0·001 and 0·03, respectively). CONCLUSIONS Despite long-term remission and improvements in fat distribution and insulin sensitivity, patients with CD may suffer from a state of chronic low-grade inflammation, which could contribute to increased cardiovascular mortality.

Abstract
CONTEXT Cushing's disease (CD) has a significant relapse rate after successful transsphenoidal surgery (TSS). Many CD patients respond aberrantly to the desmopressin test (DT). Disappearance of this response after surgery may suggest complete removal of abnormal corticotrophs and a lower possibility of recurrence. OBJECTIVE The utility of postoperative DT to predict long-term outcome compared to the widely used postoperative cortisol level. DESIGN Retrospective analysis. SETTING Tertiary hospital. PATIENTS Seventy-three patients underwent TSS and postoperative DT; 51 had sustained remission, defined as normal dexamethasone suppression and urinary free cortisol at 6 months. After excluding 12 patients with short follow-up, negative or no preoperative DT, we analyzed 39 patients. INTERVENTION(S) Measurements of morning cortisol at 1-2 weeks and DT within 6 months after TSS. MAIN OUTCOME MEASURE(S) Recurrence or remission at latest follow-up. RESULTS Mean follow-up was 63 ± 50 months. Recurrence occurred in seven patients. In logistic regression analysis, postoperative cortisol levels were not associated with remission. Apart from the percentage increment of cortisol, all other DT criteria (peak cortisol, peak ACTH, absolute cortisol increment [ΔCort], absolute ACTH change, and percentage absolute ACTH change) were significant predictors of outcome. In receiver operating characteristic analysis, the ΔCort had the best diagnostic performance. ΔCort <7.4 μg/dL had a sensitivity of 97% to detect remission. Comparison of Kaplan-Meier curves showed that ΔCort <7.4 μg/dL was associated with remission, whereas ΔCort ≥7.4 μg/dL had a hazard ratio of recurrence of 24.7 (95% confidence interval, 10.6-448.5) at 60 months (median). CONCLUSION Loss of desmopressin response indicates favorable prognosis and, if used in addition to basal cortisol levels, improves the accuracy of the postoperative assessment of CD.

Abstract
PURPOSE Quality of life (QoL) and psychosocial well-being are substantially impaired in patients with Cushing's disease (CD), not only at the acute illness stage but also after therapy; however, the reason for these impairments remains unclear. METHODS In this cross-sectional, patient-reported outcome study, we conducted a postal survey on psychosocial impairment and coping strategies in patients after surgical treatment of CD in three large tertiary referral centers. In total, 176 patients with CD completed a compilation of self-assessment inventories pertaining to depression (Hospital Anxiety and Depression Scale, HADS), QoL (Short Form SF-36, Tuebingen CD; Tuebingen CD-25), coping style (Freiburg questionnaire on coping with illness, FKV-LIS), and embitterment (Bern Embitterment Inventory), on average 6.8 ± 6.66 years after surgery. Regression analyses were performed to identify predictors of psychosocial impairment. RESULTS At the time of the study, 21.8 % of patients suffered from anxiety, 18.7 % experienced an above-average feeling of embitterment, and 13.1 % suffered from depression. Maladaptive coping styles (FKV-LIS subscales depressive coping and minimizing importance) emerged as robust and strong predictors of psychosocial impairment in all inventories; while age, sex, and hydrocortisone intake failed to explain the variance in these measures. CONCLUSION Similar to several studies in non-pituitary patient cohorts (e.g., patients with multiple sclerosis or lower back pain), our results indicate that psychosocial impairment in CD is significantly influenced by how the patient deals with the illness. Therefore, psychological training of positive coping styles could be a helpful complementary therapy in the overall treatment strategy of CD.
