Abstract
This Consensus Statement from an international, multidisciplinary workshop sponsored by the Pituitary Society offers evidence-based graded consensus recommendations and key summary points for clinical practice on the diagnosis and management of prolactinomas. Epidemiology and pathogenesis, clinical presentation of disordered pituitary hormone secretion, assessment of hyperprolactinaemia and biochemical evaluation, optimal use of imaging strategies and disease-related complications are addressed. In-depth discussions present the latest evidence on treatment of prolactinoma, including efficacy, adverse effects and options for withdrawal of dopamine agonist therapy, as well as indications for surgery, preoperative medical therapy and radiation therapy. Management of prolactinoma in special situations is discussed, including cystic lesions, mixed growth hormone-secreting and prolactin-secreting adenomas and giant and aggressive prolactinomas. Furthermore, considerations for pregnancy and fertility are outlined, as well as management of prolactinomas in children and adolescents, patients with an underlying psychiatric disorder, postmenopausal women, transgender individuals and patients with chronic kidney disease. The workshop concluded that, although treatment resistance is rare, there is a need for additional therapeutic options to address clinical challenges in treating these patients and a need to facilitate international registries to enable risk stratification and optimization of therapeutic strategies.

Abstract
CONTEXT Non-alcoholic fatty liver disease (NAFLD) is a leading causes of liver-related morbidity and mortality. While data on acromegaly, a state of chronic growth hormone (GH)/insulin-like growth factor I (IGF-I) excess, suggest an inverse relationship with intrahepatic lipid (IHL) content, less is known about the impact of the GH/IGF-I axis on IHL, lipid composition, and phosphor metabolites in individuals without disorders of GH secretion. OBJECTIVE The aim was to investigate the relation between activity of the GH/IGF-I axis and IHL content and phosphor metabolism. METHODS We performed a cross-sectional study in 59 otherwise metabolically healthy individuals (30 females), of which 16 met the criteria of NAFLD with IHL of ≥5.6%. The GH/IGF-I axis was evaluated in a fasting state and during an oral glucose tolerance test (OGTT). Insulin sensitivity was estimated by validated indices. IHL, lipid composition (unsaturation index), and phosphate metabolites were analyzed by using 1H/31P magnetic resonance spectroscopy. RESULTS In the overall cohort (40.6 ± 15 years; body mass index: 24.5 ± 3 kg/m2; IGF-I: 68.0 ± 17% upper limit of normal), fasting GH (R = -0.31; P = .02), GH during oral glucose tolerance test (R = -0.51; P < .01), and IGF-I (R = -0.28; P = .03) inversely correlated with IHL. GH levels during OGTT were significantly lower in NAFLD than in controls (47.7 [22; 143] ng/mL/min vs 16.8 [7; 32] ng/mL/min; P = .003). GH/IGF-I axis activity correlated with lipid composition and with phosphor metabolites. In multiple regression analysis, the GH/IGF-I axis activity was a strong predictor for IHL and lipid composition independent from insulin sensitivity. CONCLUSION GH/IGF-I axis activity impacts hepatic lipid and phosphate metabolism in individuals without disorders in GH secretion. Lower GH axis activity is associated with higher IHL and an unfavorable lipid composition, probably mediated by changes in hepatic energy metabolism.

Abstract
Over the past decades, adapted lifestyle and dietary habits in industrialized countries have led to a progress of obesity and associated metabolic disorders. Concomitant insulin resistance and derangements in lipid metabolism foster the deposition of excess lipids in organs and tissues with limited capacity of physiologic lipid storage. In organs pivotal for systemic metabolic homeostasis, this ectopic lipid content disturbs metabolic action, thereby promotes the progression of metabolic disease, and inherits a risk for cardiometabolic complications. Pituitary hormone syndromes are commonly associated with metabolic diseases. However, the impact on subcutaneous, visceral, and ectopic fat stores between disorders and their underlying hormonal axes is rather different, and the underlying pathophysiological pathways remain largely unknown. Pituitary disorders might influence ectopic lipid deposition indirectly by modulating lipid metabolism and insulin sensitivity, but also directly by organ specific hormonal effects on energy metabolism. In this review, we aim to I) provide information about the impact of pituitary disorders on ectopic fat stores, II) and to present up-to-date knowledge on potential pathophysiological mechanisms of hormone action in ectopic lipid metabolism.

Abstract
Introduction Osilodrostat decreases cortisol production by inhibiting 11β-hydroxylase, which increases adrenal hormones proximal to the blockade. Here, we describe these effects of osilodrostat and associated adverse events (AEs). The efficacy and safety of osilodrostat in patients with Cushing's disease (CD) were confirmed in the published Phase III, prospective LINC 3 study (NCT02180217). Methods 137 patients with CD and mUFC >1.5×upper limit of normal were enrolled into a 48-week (W) core phase that included an 8W double-blind, randomized-withdrawal period for eligible patients. Of 113 patients who completed W48, 106 opted to enter the extension, ending when all ongoing patients completed ≥72W of treatment or discontinued. Testosterone, 11-deoxycortisol, 11-deoxycorticosterone and aldosterone were assessed centrally at baseline and regular intervals by liquid chromatography-tandem mass spectrometry and dehydroepiandrosterone sulfate (DHEAS) by chemiluminescence immunoassay. Hirsutism (females; rated on a semi-quantitative scale: 0=absent; 1=mild; 2=moderate; 3=severe), blood pressure, edema and serum potassium were assessed at regular intervals. Results Median osilodrostat exposure was 130W (range, 1–245); median osilodrostat dose was 7.4 mg/day (range, 0.8–46.6). Following an initial increase during the core phase, mean (SD) testosterone levels stabilized in males and decreased towards baseline levels in females during long-term treatment. Of female patients with assessments at baseline and W48 (n=76) and W72 (n=64), hirsutism score improved from baseline in 26 and 22 patients at W48 and W72, respectively and remained unchanged in 37 and 33 patients, respectively. Mean (SD) DHEAS levels decreased during the core phase to within the normal range, then stabilized during the extension in females (1.6 [1.6] and 1.0 [0.9] µmol/L at W48 and W72, respectively) and males (3.4 [3.3] and 3.0 [3.1] µmol/L at W48 and W72, respectively). Aldosterone levels also decreased and then stabilized during long-term treatment. Adrenal hormone precursor accumulation-related AEs were reported in 58.4% (n=80/137) of patients, regardless of study drug relationship and managed with additional therapy in 36.5% (n=50/137) of patients. They mostly occurred during the first 26W of treatment (35.5% and 49.1% in females and males, respectively) and at different osilodrostat doses (1–60 mg), with no discernable dose-related effect. Although mean potassium levels remained stable, AEs of hypertension, peripheral edema and hypokalemia were the most common adrenal hormone precursor accumulation-related AEs and were reported in 24 (17.5%), 22 (16.1%) and 18 (13.1%) patients, respectively; managed with concomitant medication in 17, 6 and 14 patients, respectively. Overall, few patients discontinued because of adrenal hormone precursor accumulation-related AEs (1.5%; n=2/137). Conclusions Adrenal hormone levels frequently change upon initiation of osilodrostat but stabilize during long-term treatment. AEs associated with these changes can occur and are manageable without osilodrostat discontinuation. These AEs should be closely monitored and treatment initiated as needed to achieve optimal patient outcomes. Presentation: Monday, June 13, 2022 12:30 p.m. - 2:30 p.m.

Abstract
Background In healthy subjects, nadir growth hormone (GH) concentrations following an oral glucose load are related to BMI, gender and estrogen use. To date, very few data exist on factors influencing nadir GH in patients with acromegaly. Methods Glucose suppression tests (2h-75g) were performed in 166 patients with acromegaly not receiving any acromegaly-specific medical therapy: 132 OGTTs were performed at the initial disease diagnosis and 126 after at least one pituitary surgery. Glucose, insulin and C-peptide were measured every 30 minutes and the metabolic response was evaluated by minimal model analysis. Uni- and multivariate regression analysis was performed to test the relationship between nadir GH concentrations, patient characteristics and parameters of disease activity, lipid and glucose metabolism. Results In patients with active acromegaly (46% males), nadir glucose concentrations positively correlated to fasting IGF-1 (expressed as fold-ULN; p<0. 001), fasting insulin and C-peptide (both p=0. 004), HOMA-insulin resistance index (p=0. 016), and prehepatic beta-cell function (p=0. 002), but not to BMI and gender. In multivariate analysis, fasting C-peptide and IGF-1 were both independent predictors of nadir GH levels in patients with newly diagnosed acromegaly (p<0. 001). When testing for sex-specific predictors of nadir GH, we found a negative relationship between nadir GH and age in male patients, but not in females. After surgery, IGF-1 decreased from 805.5 (3.2 xULN, IQR 437.8) to 277.5 ng/ml (1.1 xULN, IQR 234. 0) and nadir GH after glucose suppression decreased from 8.8 (IQR 16.2) to 0.5 ng/ml (IQR 1.9). The decrease in biomarkers of disease activity following surgery leads to changes in predictors of nadir GH: postoperatively nadir GH relates to IGF-1 (p<0. 001), prehepatic beta-cell function (p=0. 02), weight (p=0. 031) and BMI (p=0. 044), with beta-cell-function being the only independent predictor in multivariate analysis (p=0. 003). When postoperative OGTTs performed in men and women were separately analyzed, nadir GH remained in a positive relationship to GH and IGF-1 in both sexes, but the relationship with beta-cell-function and other parameters of glucose metabolism remained significant only in male patients. In addition, postoperative nadir GH in male patients positively relates to LDL-cholesterol and triglycerides, and negatively to gonadal axis activity. Conclusion Here we describe that nadir GH concentrations in patients with acromegaly are mainly determined by parameters of disease activity and beta-cell function, but not by BMI and sex. A positive relationship between nadir GH and weight/BMI is only observed following improvement of disease activity after surgery, but appears mainly influenced by morphologic gender differences, as it disappears when male and female cohorts are analyzed separately.

Abstract
OBJECTIVE To investigate the long-term efficacy and tolerability of osilodrostat, a potent oral 11β-hydroxylase inhibitor, for treating Cushing's disease (CD). DESIGN/METHODS A total of 137 adults with CD and mean 24-h urinary free cortisol (mUFC) > 1.5 × upper limit of normal (ULN) received osilodrostat (starting dose 2 mg bid; maximum 30 mg bid) during the prospective, Phase III, 48-week LINC 3 (NCT02180217) core study. Patients benefiting from osilodrostat at week 48 could enter the optional extension (ending when all patients had received ≥ 72 weeks of treatment or discontinued). Efficacy and safety were assessed for all enrolled patients from the core study baseline. RESULTS Median osilodrostat exposure from the core study baseline to study end was 130 weeks (range 1-245) and median average dose was 7.4 mg/day (range 0.8-46.6). The reduction in mean mUFC achieved during the core was maintained during the extension and remained ≤ ULN. Of 106 patients, 86 (81%) patients who entered the extension had mUFC ≤ ULN at week 72. Improvements in cardiovascular/metabolic-related parameters, physical manifestations of hypercortisolism (fat pads, central obesity, rubor, striae, and hirsutism in females), and quality of life in the core study were also maintained or improved further during the extension. No new safety signals were reported; 15/137 (10.9%) and 12/106 (11.3%) patients discontinued for adverse events during the core and extension, respectively. Mean testosterone in females decreased towards baseline levels during the extension. CONCLUSIONS Data from this large, multicentre trial show that long-term treatment with osilodrostat sustains cortisol normalisation alongside clinical benefits in most patients with CD and is well tolerated.

Abstract
BACKGROUND In patients with transthyretin amyloid cardiomyopathy, tafamidis was shown to slow the decline in 6-minute walking distance as compared with placebo. We aimed to define the impact of tafamidis and optimal background treatment on functional capacity as determined by cardiopulmonary exercise testing (CPET). METHODS Seventy-eight consecutive patients were enrolled in the study. They underwent CPET at baseline, and outcome defined as death or heart failure hospitalization was obtained for a time period of up to 30 months. Fifty-four patients completed a follow-up CPET at 9±3 months (range, 4-16 months). Improvement in peak VO2 at follow-up was defined as ∆peak VO2≥1.0 mL/(kg·min), stable peak VO2 was defined as 0≤∆peak VO2<1.0 mL/(kg·min), and decline in peak VO2 was defined by ∆peak VO2<0 mL/(kg·min). RESULTS Baseline peak VO2>14 mL/(kg·min) as well as minute ventilation/carbon dioxide production slope≤34 were associated with a lower risk of death or heart failure hospitalization (P=0.002, P=0.007, respectively). In 54 patients, who received tafamidis and underwent repeat CPET testing, an improvement in physical performance (P=0.002) was observed at follow-up. When comparing pre and post-treatment parameters, 29 patients (54%) showed an increase in percent predicted peak VO2 (P<0.0001), an improvement of peak VO2 (P<0.0001), and better physical performance at follow-up (P<0.0001). Patients with stable or improved peak VO2 had less advanced heart disease at baseline (P=0.046). CONCLUSIONS Our findings demonstrate that baseline peak VO2 and baseline minute ventilation/carbon dioxide production slope predict outcomes and an improvement in physical performance as measured by CPET was observed in patients receiving tafamidis, who had less advanced disease at baseline, emphasizing the importance of early diagnosis.

Abstract
CONTEXT Data on long-term safety of growth hormone (GH) replacement in adults with GH deficiency (GHD) are needed. OBJECTIVE We aimed to evaluate the safety of GH in the full KIMS (Pfizer International Metabolic Database) cohort. METHODS The worldwide, observational KIMS study included adults and adolescents with confirmed GHD. Patients were treated with GH (Genotropin [somatropin]; Pfizer, NY) and followed through routine clinical practice. Adverse events (AEs) and clinical characteristics (eg, lipid profile, glucose) were collected. RESULTS A cohort of 15 809 GH-treated patients were analyzed (mean follow-up of 5.3 years). AEs were reported in 51.2% of patients (treatment-related in 18.8%). Crude AE rate was higher in patients who were older, had GHD due to pituitary/hypothalamic tumors, or adult-onset GHD. AE rate analysis adjusted for age, gender, etiology, and follow-up time showed no correlation with GH dose. A total of 606 deaths (3.8%) were reported (146 by neoplasms, 71 by cardiac/vascular disorders, 48 by cerebrovascular disorders). Overall, de novo cancer incidence was comparable to that in the general population (standard incidence ratio 0.92; 95% CI, 0.83-1.01). De novo cancer risk was significantly lower in patients with idiopathic/congenital GHD (0.64; 0.43-0.91), but similar in those with pituitary/hypothalamic tumors or other etiologies versus the general population. Neither adult-onset nor childhood-onset GHD was associated with increased de novo cancer risks. Neutral effects were observed in lipids/fasting blood glucose levels. CONCLUSION These final KIMS cohort data support the safety of long-term GH replacement in adults with GHD as prescribed in routine clinical practice.

Abstract
Ein wichtiges Ziel bei der Behandlung der Nebenniereninsuffizienz ist die Prävention der Nebennierenkrise (auch akute Nebenniereninsuffizienz oder Addison-Krise genannt). Um in Österreich eine bessere Implementierung sowie Harmonisierung der Maßnahmen zur Prävention und Therapie der Nebennierenkrise zu erreichen, wurde dieses Konsensusdokument erarbeitet. Folgende Maßnahmen werden grundsätzlich für alle Patient*innen mit Nebenniereninsuffizienz empfohlen und in diesem Manuskript ausführlich erörtert: 1. Versorgung mit einer Notfallkarte („steroid emergency card“) sowie evtl. auch mit einem Armband oder einer Halskette (oder Ähnlichem) mit medizinischem Alarmhinweis „Nebenniereninsuffizienz, benötigt Glukokortikoide“. 2. Versorgung mit einem Hydrocortison-Notfallkit zur Injektion (alternativ auch Suppositorien/Zäpfchen zur Notfallapplikation) sowie ausreichenden oralen Glukokortikoiddosen für Stresssituationen/Erkrankungen. 3. Schulung von Patient*innen und Angehörigen zur Steigerung der Glukokortikoidtherapie in Stresssituationen bzw. bei Erkrankungen („sick day rules“) und zur Selbstinjektion von Hydrocortison. 4. Versorgung mit einer Behandlungsleitlinie (Informationszettel) zur Prävention und Therapie der Nebennierenkrise, welche bei Bedarf auch dem Gesundheitspersonal gezeigt werden soll. 5. Versorgung mit einer Notfall-Telefonnummer des behandelnden endokrinologischen Teams und/oder medizinisch geschulter Betreuungspersonen bzw. Angehöriger. 6. Regelmäßige (vorzugsweise jährliche) Wiederholung der Schulungsmaßnahmen. Dieses Konsensusdokument beinhaltet auch ausführliche Empfehlungen für die perioperative Glukokortikoidtherapie sowie für diverse andere Stresssituationen.

Abstract
Abstract
Patients with Cushing’s disease (CD) may present with both chronic and acute perioperative complications that necessitate multidisciplinary care. This review highlights several objectives for these patients before and after transsphenoidal surgery. Preoperative management includes treatment of electrolyte disturbances, cardiovascular comorbidities, prediabetes/diabetes, as well as prophylactic consideration(s) for thromboembolism and infection(s). Preoperative medical therapy (PMT) could prove beneficial in patients with severe hypercortisolism or in cases of delayed surgery. Some centers use PMT routinely, although the clinical benefit for all patients is controversial. In this setting, steroidogenesis inhibitors are preferred because of rapid and potent inhibition of cortisol secretion. If glucocorticoids are not used perioperatively, an immediate remission assessment postoperatively is possible. However, perioperative glucocorticoid replacement is sometimes necessary for clinically unstable or medically pretreated patients and for those patients with surgical complications. A nadir serum cortisol < 2-5µg/dl during 24-74 hours postoperatively is generally accepted as remission; higher values suggest non-remission, while a few patients may display delayed remission. If remission is not achieved, additional treatments are pursued. The early postoperative period necessitates multidisciplinary awareness for early diagnosis of adrenal insufficiency (AI) to avoid adrenal crisis, which may be also potentiated by acute postoperative complications. Preferred glucocorticoid replacement is hydrocortisone, if available. Assessment of recovery from postoperative AI should be undertaken periodically. Other postoperative targets include decreasing antihypertensive/diabetic therapy if in remission, thromboprophylaxis, infection prevention/treatment, and management of electrolyte disturbances and/or potential pituitary deficiencies. Evaluation of recovery of thyroid, gonadal and growth hormone deficiencies should be also performed in the following months postoperatively.

Abstract
OBJECTIVE To evaluate the combined predictive value of MRI criteria with the prolactin-volume-ratio (PVR) to differentiate prolactinoma from non-prolactinoma, in small sellar lesions with hyperprolactinemia. METHODS Retrospective analysis of 55 patients with sellar lesions of ≤15 mm diameter on MRI and hyperprolactinemia of ≤150 ng/mL, surgically treated between 2003 and 2020 at the Medical University of Vienna, with a conclusive histopathological report. Serum prolactin levels, extent of pituitary stalk deviation, size and volume of the lesion were assessed. The PVR was calculated by dividing the preoperative prolactin level by tumor volume. RESULTS Our study population consisted of 39 patients (71%) with a prolactin-producing pituitary adenoma (group A), while 16 patients (29%) had another type of sellar lesion (group B). Patients in group A were significantly younger (p=0.012), had significantly higher prolactin levels at diagnosis (p<0.001) as well as smaller tumor volume (p=0.036) and lower degree of pituitary stalk deviation (p=0.009). The median PVR was significantly higher in group A (243 ng/mL per cm3) than in group B (83 ng/mL per cm3; p=0.002). Furthermore, the regression operating characteristics analysis revealed a PVR >100 ng/mL per cm3 to be predictive for distinguishing prolactin-producing lesions from other small sellar lesions. CONCLUSION In patients with small sellar lesions, Prolactin-Volume-Ratios >100 represents a possible predictive marker for the diagnosis of prolactin-producing pituitary adenomas.

Abstract
OBJECTIVE To evaluate diagnostic accuracy of the corticotropin-releasing hormone (CRH) stimulation test and the overnight 8 mg dexamethasone suppression test (DST) for the differentiation of Cushing's disease (CD) and ectopic Cushing's syndrome (ECS). METHODS Retrospective study in 6 European centers. Inclusion criteria: patients with a) overt adrenocorticotropin (ACTH)-dependent Cushing's syndrome at the time of dynamic testing, b) histopathological confirmed tumors and/or c) postoperative biochemical remission and/or adrenal insufficiency. Optimal cut-offs were calculated via receiver operating characteristic (ROC) analysis using CD as reference. RESULTS 469 patients were analyzed [78% females; median age 43 years (IQR 19)]. CRH test and overnight 8 mg DST were performed in 420 [CD, n=394 (94%); ECS, n=26 (6%)] and 237 patients [228 CD (96%), 9 ECS (4%)]. Both tests were performed in 205 patients (44%). The post-CRH %-increase at 30 minutes of both ACTH (cut-off ≥31%, sensitivity 83%, specificity 85%, AUC 0.81) and cortisol (cut-off ≥12%, sensitivity 82%, specificity 89%, AUC 0.86) discriminated best between CD and ECS. A test duration of >60 minutes did not improve diagnostic performance of the CRH test. The optimal cortisol cut-off for the %-suppression during the 8 mg DST was ≥55% (sensitivity 80%, specificity 78%, AUC 0.75). CONCLUSION The CRH test has equivalent sensitivity but higher specificity than the 8 mg DST and is therefore the test of first choice. The diagnostic outcome of ACTH and cortisol is well comparable, however, sampling beyond 60 minutes post-CRH does not provide diagnostic benefits.

Abstract
Cushing's disease requires accurate diagnosis, careful treatment selection, and long-term management to optimise patient outcomes. The Pituitary Society convened a consensus workshop comprising more than 50 academic researchers and clinical experts to discuss the application of recent evidence to clinical practice. In advance of the virtual meeting, data from 2015 to present about screening and diagnosis; surgery, medical, and radiation therapy; and disease-related and treatment-related complications of Cushing's disease summarised in recorded lectures were reviewed by all participants. During the meeting, concise summaries of the recorded lectures were presented, followed by small group breakout discussions. Consensus opinions from each group were collated into a draft document, which was reviewed and approved by all participants. Recommendations regarding use of laboratory tests, imaging, and treatment options are presented, along with algorithms for diagnosis of Cushing's syndrome and management of Cushing's disease. Topics considered most important to address in future research are also identified.

Abstract
BACKGROUND Based on the complex pathophysiology of type 2 diabetes and atherosclerosis we hypothesized a dynamic change in prognostic value of cardiovascular biomarkers over time. METHODS In this prospective study 746 patients with type 2 diabetes mellitus, being followed up for 60 months were analysed. The primary endpoint was defined as unplanned hospitalization for cardiovascular disease or death. Beside others, especially the prognostic performance of the biomarkers of interest (GDF-15, NT-proBNP, hs-TnT) was evaluated in relation to quartiles of diabetes duration. RESULTS In patients having a diabetes duration below 7 years lnGDF-15 (HR 2.84; p < 0.01) and lnhs-TnT (HR 2.96; p < 0.01) were significant predictors of the primary endpoint. LnAge (HR 40.01; p < 0.01) and lnNT-proBNP (HR 1.56; p = 0.03) were significant predictors in patients with a diabetes duration between 7 and 12 years. In the third quartile (diabetes duration 12-22 years) lnurinary albumin to creatinine ratio (HR 1.25; p = 0.005) and lnNT-proBNP (HR 2.13, p < 0.001) predicted the endpoint. In patients with a diabetes duration above 22 years, lnAge (HR 75.35; p = 0.001) and lnNT-proBNP (HR 2.0; p < 0.01) were the only significant predictors of the endpoint. CONCLUSION Prognostic power of cardiovascular biomarkers changes dynamically in relation to duration of type 2 diabetes mellitus. In patients with shorter duration of the disease markers of subclinical cardiovascular dysfunction and inflammation perform better than markers of systemic advanced organ dysfunction and cardiovascular disease.

Abstract
Pituitary adenomas count among the most common intracranial tumors. During pituitary oncogenesis structural, textural, metabolic and molecular changes occur which can be revealed with our integrated ultrahigh-resolution multimodal imaging approach including optical coherence tomography (OCT), multiphoton microscopy (MPM) and line scan Raman microspectroscopy (LSRM) on an unprecedented cellular level in a label-free manner. We investigated 5 pituitary gland and 25 adenoma biopsies, including lactotroph, null cell, gonadotroph, somatotroph and mammosomatotroph as well as corticotroph. First-level binary classification for discrimination of pituitary gland and adenomas was performed by feature extraction via radiomic analysis on OCT and MPM images and achieved an accuracy of 88%. Second-level multi-class classification was performed based on molecular analysis of the specimen via LSRM to discriminate pituitary adenomas subtypes with accuracies of up to 99%. Chemical compounds such as lipids, proteins, collagen, DNA and carotenoids and their relation could be identified as relevant biomarkers, and their spatial distribution visualized to provide deeper insight into the chemical properties of pituitary adenomas. Thereby, the aim of the current work was to assess a unique label-free and non-invasive multimodal optical imaging platform for pituitary tissue imaging and to perform a multiparametric morpho-molecular metabolic analysis and classification.

Abstract
Introduction: Hyper- and hypofunction of the hypothalamic-pituitary-adrenal (HPA) axis in Cushing’s syndrome (CS) and Addison’s disease (AD) is associated with disturbances of classical feedback mechanisms. Time to recovery of adrenal function after CS remission depends on the etiology of CS and is longest after adrenal CS. To date there are no data on the recovery of corticotroph function following CS remission, and the synacthen test is recommended for testing adrenal function in patients with hypopituitarism. Aim Here we aim to test corticotroph function after long-term cure of Cushing’s syndrome following bilateral adrenalectomy (BADx), compared to patients with primary glucocorticoid deficiency due the presence of 21-hydroxylase antibodies or adrenoleucodystrophy, a pathophysiological model of glucocorticoid and mineralocorticoid deficiency. Methods: We retrospectively evaluated data from patients with CS and AD attending our endocrine department between 2000 and 2020, using the following inclusion criteria: BADx performed for pituitary/ectopic/adrenal or occult CS or primary adrenal insufficiency confirmed either by the presence of 21-hydroxylase antibodies or genetically in adrenoleucodystrophy. Results: Full data were available for 93 patients: 43 patients with BADx due to CS (18 patients with pituitary CS, 14 patients with adrenal CS and 11 patients with ectopic/occult CS, F:M 29:14, mean age at BADx 45.4 years age range 13-74 years) and 50 patients with AD (47 cases with positive 21-hydroxylase antibodies, 3 cases with adrenoleucodystrophy, F:M ratio 27:23, mean age at diagnosis 35 years, age range 6-57 years). The observation period was 537.5 patient-years after BADx (mean 12.5 years, range 1-38 years) and 647 patient-years following AD diagnosis (mean 14.2 years, range 1-46 years). At the last visit, there were no differences between the hormone substitution regimes between the groups. ACTH concentrations during the whole observation period and also at the last visit were lowest in patients with adrenal CS (56.5 pg/ml) when compared to patients with AD (487 pg/ml, p<0.001), or with patients with pituitary CS (377.5 pg/mL, p=0.011). ACTH values in patients with AD in long-term follow-up were significantly higher when compared to all patients with CS (141 pg/mL, p<0.001). Conclusion: These data highlight a long-term defective corticotroph function in patients with CS following BADx. Low ACTH concentrations long term after BADx for adrenal CS corroborate that corticotroph function fails to recover after CS cure. In the light of these findings, the utility of the synacthen test for excluding secondary/tertiary adrenal insufficiency following CS remission is disputable and remains to be evaluated in future studies dedicated to CS cohorts.

Abstract
CONTEXT Cushing syndrome (CS) results in significant morbidity and mortality. OBJECTIVE To study acute and life-threatening complications in patients with active CS. METHODS We performed a retrospective cohort study using inpatient and outpatient records of patients with CS in a tertiary center. A total of 242 patients with CS were included, including 213 with benign CS (pituitary n = 101, adrenal n = 99, ectopic n = 13), and 29 with malignant disease. We collected acute complications necessitating hospitalization, from appearance of first symptoms of hypercortisolism until 1 year after biochemical remission. Mortality data were obtained from the national registry. Baseline factors relating to and predicting acute complications were tested using uni- and multivariate analysis. RESULTS The prevalence of acute complications was 62% in patients with benign pituitary CS, 40% in patients with benign adrenal CS, and 100% in patients with ectopic CS. Complications observed in patients with benign CS included infections (25%), thromboembolic events (17%), hypokalemia (13%), hypertensive crises (9%), cardiac arrhythmias (5%), and acute coronary events (3%). Among these patients, 23% had already been hospitalized for acute complications before CS was suspected, and half of complications occurred after the first surgery. Glycated hemoglobin (HbA1c) and 24-hour urinary free cortisol positively correlated with the number of acute complications per patient. Patients with malignant disease had significantly higher rates of acute complications. Mortality during the observation period was 2.8% and 59% in benign and malignant CS, respectively. CONCLUSIONS This analysis highlights the whole spectrum of acute and life-threatening complications in CS, and their high prevalence even before disease diagnosis and after successful surgery.

Abstract
Cushing's syndrome (CS) is associated with increased mortality that is driven by cardiovascular, thromboembolic, and infection complications. Although these events are expected to decrease during disease remission, incidence often transiently increases postoperatively and is not completely normalized in the long-term. It is important to diagnose and treat cardiovascular, thromboembolic, and infection complications concomitantly with CS treatment. Management of hyperglycemia/diabetes, hypertension, hypokalemia, hyperlipidemia, and other cardiovascular risk factors is generally undertaken in accordance with clinical care standards. Medical therapy for CS may be needed even prior to surgery in severe and/or prolonged hypercortisolism, and treatment adjustments can be made based on disease pathophysiology and drug-drug interactions. Thromboprophylaxis should be considered for CS patients with severe hypercortisolism and/or postoperatively, based on individual risk factors of thromboembolism and bleeding. Pneumocystis jiroveci pneumonia prophylaxis should be considered for patients with high urinary free cortisol at the initiation of hypercortisolism treatment.

Abstract
OBJECTIVE Despite advancements of intraoperative visualization, the difficulty to visually distinguish adenoma from adjacent pituitary gland due to textural similarities may lead to incomplete adenoma resection or impairment of pituitary function. The aim of this study was to investigate optical coherence tomography (OCT) imaging in combination with a convolutional neural network (CNN) for objectively identify pituitary adenoma tissue in an ex vivo setting. METHODS A prospective study was conducted to train and test a CNN algorithm to identify pituitary adenoma tissue in OCT images of adenoma and adjacent pituitary gland samples. From each sample, 500 slices of adjacent cross-sectional OCT images were used for CNN classification. RESULTS OCT data acquisition was feasible in 19/20 (95%) patients. The 16.000 OCT slices of 16/19 of cases were employed for creating a trained CNN algorithm (70% for training, 15% for validating the classifier). Thereafter, the classifier was tested on the paired samples of three patients (3.000 slices). The CNN correctly predicted adenoma in the 3 adenoma samples (98%, 100% and 84% respectively), and correctly predicted gland and transition zone in the 3 samples from the adjacent pituitary gland. CONCLUSION Trained convolutional neural network computing has the potential for fast and objective identification of pituitary adenoma tissue in OCT images with high sensitivity ex vivo. However, further investigation with larger number of samples is required.

Abstract
Pituitary hormone axes modulate glucose metabolism and exert direct or indirect effects on insulin secretion and function. Cortisol and growth hormone are potent insulin-antagonistic hormones. Therefore impaired glucose tolerance, elevated fasting glucose concentrations and diabetes mellitus are frequent in Cushing's disease and acromegaly. Also prolactinomas, growth hormone (GH) deficiency, hypogonadism and hypothyroidism might be associated with impaired glucose homeostasis but usually to a lesser extent. Therefore glucose metabolism needs to be closely monitored and treated in patients with pituitary adenomas. Correction of the pituitary dysfunction is frequently followed by improvement of glucose homeostasis.

Abstract
Abstract
Introduction
Cushing’s syndrome is associated with significant chronic and acute comorbidities including acute thromboembolic and cardiovascular events. To date, there are no data on the prevalence and predictors of acute and perioperative complications in patients with active Cushing’s syndrome.
Methods
In a single-center cohort analysis we evaluate predictors and outcomes of acute, life-threatening and perioperative complications in patients with active biochemically verified Cushing’s syndrome attending our endocrine department between 1978 and 2016. Any medical complications necessitating hospitalization, including admission to intensive care units (ICUs), from the time of appearance of first symptoms of hypercortisolism until one year after biochemical remission by surgery (or where surgical remission was not achieved, during continuing follow-up) were recorded and classified. Baseline factors related to and predicting acute complications were tested using uni- and multivariate analysis.
Results
The study included 242 patients (m/f n=54/188) with Cushing’s syndrome (pituitary n=99, adrenal n=116, ectopic n=27), 14.0% of which had malignant disease.
At least one acute complication was observed in 54.5% of patients; these included electrolyte disturbances (24.4%), infections (27.7%), thromboembolic events (14.9%), cardiac arrhythmias necessitating medical intervention (5.4%), hypertensive crises (8.7%), acute coronary events (3.3%) and cerebrovascular events (4.1%). At least one ICU admission (excluding post-surgical observance) was required in 13.2% of patients. The majority of complications occurred prior to surgery (60-90%); infections occurred pre- and postoperatively (51.7% vs 48.3%, respectively).
Patients with ectopic Cushing’s syndrome demonstrated a higher likelihood of infection (p<0.001), hypokalemia (p<0.001) and ICU stays (p=0.009) compared to patients with pituitary or adrenal Cushing’s syndrome. Patients with diabetes mellitus at diagnosis (n=81) had a significantly higher frequency of infection (p<0.001), hypokalemia (p<0.001), hypertensive crises (p=0.004), acute coronary events (p=0.029), arrhythmias (p=0.025) and a higher likelihood of an ICU stay (p<0.001).
The total number of acute complications and the number of days at ICU correlated positively with parameters of cortisol excess including urinary free cortisol and the time of hypercortisolism.
Conclusion
This cohort analysis identifies a significantly high prevalence of acute and perioperative complications in Cushing’s syndrome, with one in eight patients suffering a life-threatening situation necessitating ICU admission. These acute complications are positively predicted by the degree of hypercortisolism, emphasizing the necessity for acute interventions aiming to reduce cortisol excess even before definitive disease cure is achieved.

Abstract
Background Patients with active acromegaly exhibit low hepatocellular lipid content (HCL) despite pronounced insulin resistance. This contrasts the strong association of insulin resistance with non-alcoholic fatty liver disease in the general population. Acromegaly may therefore help to elucidate antisteatotic pathways. Since low HCL in acromegaly might be caused by changes in oxidative substrate metabolism and interorgan crosstalk we investigated mitochondrial activity and plasma metabolomics as well as lipidomics in active acromegaly. Approach & Results Patients In this cross-sectional study, 15 patients with active acromegaly (ACRO) and 17 healthy controls (CON) matched for age, BMI, gender and body composition were included. All participants were invited to undergo 31P/1H-7T-MR-spectroscopy of the liver and skeletal muscle, as well as plasma metabolomic profiling and an oral glucose tolerance test. In comparison to CON, ACRO were insulin resistant, and showed significant lower HCL but their hepatic ATP-synthesis rate adjusted to HCL was significantly increased (h_kATP:0.19[0.14;0.24]vs0.28[0.22;0.34]s-1);p=0.024). Furthermore, the HCL-adjusted ratio of unsaturated to saturated intracellular fatty acids was decreased in ACRO (8.4%vs25.5% of HCL,p<0.04). In skeletal muscle, intramyocellular lipids and ATP-synthesis rate were significantly decreased in ACRO. Plasma lipids and lipidomics did not differ between ACRO and CON, but decreased levels of carnitine species were observed in ACRO. Conclusions The dissociation of hepatic lipid content and peripheral insulin resistance in acromegaly is associated with high mitochondrial activity as indicated by liver specific upregulation of the ATP-synthesis rate. This is paralleled by a decreased ratio of unsaturated-to-saturated lipids in hepatocytes and by a change in circulating carnitine species, also reflecting an increased mitochondrial activity. Our findings hint at potential direct effects of growth hormone excess on hepatic lipid and energy metabolism.

Abstract
OBJECTIVE According to the latest WHO classification of tumors of endocrine organs in 2017, plurihormonal adenomas are subclassified by their transcription factor (TF) expression. In the group of plurihormonal adenomas with unusual immunohistochemical combinations (PAWUC), the authors identified a large fraction of adenomas expressing TFs for gonadotroph adenoma (TFGA) cells in addition to other TFs. The aim of this study was to compare clinicopathological parameters of PAWUC with TFGA expression to gonadotroph adenomas that only express TFGA. METHODS This retrospective single-center series comprises 73 patients with TFGA-positive pituitary adenomas (SF1, GATA3, estrogen receptor α): 22 PAWUC with TFGA (TFGA-plus group) and 51 with TFGA expression only (TFGA-only group). Patient characteristics, outcome parameters, rate of invasiveness (assessed by direct endoscopic inspection), and MIB1 and MGMT status were compared between groups. RESULTS Patients in the TFGA-plus group were significantly younger than patients in the TFGA-only group (age 46 vs 56 years, respectively; p = 0.007). In the TFGA-only group, pituitary adenomas were significantly larger (diameter 25 vs 18.3 mm, p = 0.002). Intraoperatively, signs of invasiveness were significantly more common in the TFGA-plus group than in the TFGA-only group (50% vs 16%, p = 0.002). Gross-total resection was significantly lower in the nonfunctioning TFGA-plus group than in the TFGA-only group (44% vs 86%, p = 0.004). MIB1 and MGMT status showed no significant difference between groups. CONCLUSIONS These data suggest a more aggressive behavior of TFGA-positive adenomas if an additional TF is expressed within the tumor cells. Shorter radiographic surveillance and earlier consideration for retreatment should be recommended in these adenoma types.

Abstract
SummaryThe purpose of this study was to investigate the relationship of social anxiety and insulin-dependent diabetes mellitus (n = 40 girls between 13 and 19 years of age). Mean duration of diabetes was 7 years. We supposed that this chronic illness may provoke feelings of friendlessness and sadness, social withdrawal and fear of social situations because diabetes entails a series of demands which differentiate the diabetic child from healthy children. Our population was compared with 35 healthy young girls. All were administered the Schedule for Affective Disorders and Schizophrenia for School-Age-Children and completed the State Trait Anxiety Inventory for Children, the Self-Consciousness Scale and the Imaginary Audience Scale. Diagnoses of anxiety disorders across DSM-IIIR do not show significant differences between groups. In self-report inventories, our findings do not support the hypothesis that social anxiety is a pathological symptom in diabetic subjects. However, they were more depressed than the control group. Furthermore, social functioning of the diabetic group did not differ from that of the control group. They were more concerned with their illness than with social anxiety.

Abstract
AbstractAimTo study the types of psychiatric problem encountered in children infected with the human immunodeficiency virus (HIV) and their relationship to central nervous system disorder and the severity of infection.Methods17 HIV-infected children presenting with psychiatric problems were included. Mental disorders were evaluated according to DSM-IV criteria. Neurological disorders and progressive encephalopathy (presence or absence) diagnosis were evaluated by clinical and radiological examination. The severity of infection was assessed by the percentage of CD4 lymphocytes.ResultsThe most frequent diagnoses were major depression (MDD: 47%) and attention deficit hyperactivity disorder (ADHD: 29%). Major depression diagnosis was significantly associated with neuroimaging or clinical neurological abnormalities (p < 0.01). In contrast, no association was found between hyperactivity diagnosed according to DSM-IV criteria and central nervous system disorder. Percentage of CD4 lymphocytes were close to 0 for more than 80% of children presenting with psychiatric complications.ConclusionThe very low % of CD4 lymphocytes of these children suggest that the appearance of a psychiatric complication should be regarded as a factor indicating severe HIV infection. Depressive disorders may be a clinical form of encephalopathy.

Abstract
BACKGROUND Current standard treatment of microprolactinomas is dopamine agonist therapy. As this drug treatment is lifelong in up to 80% of cases, many patients consult pituitary surgeons regarding a surgical alternative. OBJECTIVE To identify prognostic criteria for surgical remission, we reviewed outcomes of our series of microprolactinomas treated with endoscopic transsphenoidal surgery, with a special emphasis on magnetic resonance adenoma delineation and position. METHODS Our study cohort comprises a single center series of 60 patients operated for histopathologically verified magnetic resonance imaging unequivocally identifiable endosellar microprolactinoma between 2003 and 2017. In 31 patients the adenoma was enclosed by pituitary gland (group ENC), in 29 patients the adenoma was located lateral to the gland adherent to the medial cavernous sinus wall (group LAT). RESULTS After a mean follow-up of 37 mo (range 4-143 mo), remission rate was significantly higher in adenomas enclosed by pituitary gland (group ENC) than adenomas located lateral to the gland (group LAT), with 87% vs 45%, P = .01. Intraoperatively, 4 patients showed signs of invasiveness. Preoperative prolactin levels did not differ between the groups (mean 155 and 187 ng/ml in group ENC and LAT, respectively).A binary logistic regression model revealed that only the radiological criteria applied showed a significant correlation (P = .003) with endocrine remission. CONCLUSION According to our results, remission rate is significantly higher in microprolactinomas enclosed by the pituitary gland. However, the decision for surgery should take into account surgeons experience and possibility of complications.

Abstract
Patients with active acromegaly (ACRO) exhibit low hepatocellular lipids (HCL), despite pronounced insulin resistance (IR). This contrasts the strong association of IR with nonalcoholic fatty liver disease in the general population. Since low HCL levels in ACRO might be caused by changes in oxidative substrate metabolism, we investigated mitochondrial activity and plasma metabolomics/lipidomics in active ACRO. Fifteen subjects with ACRO and seventeen healthy controls, matched for age, BMI, sex, and body composition, underwent 31P/1H-7-T MR spectroscopy of the liver and skeletal muscle as well as plasma metabolomic profiling and an oral glucose tolerance test. Subjects with ACRO showed significantly lower HCL levels, but the ATP synthesis rate was significantly increased compared with that in controls. Furthermore, a decreased ratio of unsaturated-to-saturated intrahepatocellular fatty acids was found in subjects with ACRO. Within assessed plasma lipids, lipidomics, and metabolomics, decreased carnitine species also indicated increased mitochondrial activity. We therefore concluded that excess of growth hormone (GH) in humans counteracts HCL accumulation by increased hepatic ATP synthesis. This was accompanied by a decreased ratio of unsaturated-to-saturated lipids in hepatocytes and by a metabolomic profile, reflecting the increase in mitochondrial activity. Thus, these findings help to better understanding of GH-regulated antisteatotic pathways and provide a better insight into potentially novel therapeutic targets for treating NAFLD.

Abstract
CONTEXT Human reproduction is mainly governed from the hypothalamic-adrenal-gonadal (HPG) axis, which controls both ovarian morphology and function. Disturbances in the secretion of other anterior pituitary hormones (and their respective endocrine axes) interfere with HPG activity and have been linked to fertility problems. In normal pregnancy, maintenance of homeostasis is associated with continuous changes in pituitary morphology and function, which need to be considered during hormone replacement in patients with hypopituitarism. DESIGN We conducted a systematic PubMed literature review from 1969 to 2019, with the following keywords: fertility and hypopituitarism, pregnancy and hypopituitarism, and ovulation induction and hypopituitarism. Case reports or single-case series of up to 2 patients/4 pregnancies were excluded. RESULTS Eleven publications described data on fertility (n = 6) and/or pregnancy (n = 7) in women with hypopituitarism. Women with hypopituitarism often need assisted reproductive treatment, with pregnancy rates ranging from 47% to 100%. In patients achieving pregnancy, live birth rate ranged from 61% to 100%. While glucocorticoids, levothyroxine, and desmopressin are safely prescribed during pregnancy, growth hormone treatment regimens vary significantly between countries, and several publications support a positive effect in women seeking fertility. CONCLUSIONS In this first systematic review on fertility, ovulation induction, and pregnancy in patients with hypopituitarism, we show that while literature is scarce, birth rates are high in patients achieving pregnancy. However, prospective studies are needed for evaluating outcomes in relationship to treatment patterns. Replacement therapy in hypopituitarism should always mimic normal physiology, and this becomes challenging with changing demands during pregnancy evolution.

Abstract
OBJECTIVE To examine all-cause mortality rates in patients with acromegaly on pegvisomant and identify pertinent risk factors, including insulin-like growth factor I (IGF-I). DESIGN Retrospective cohort analysis of data from ACROSTUDY (global surveillance study of patients with acromegaly treated with pegvisomant). METHODS Kaplan-Meier analyses and Cox regression techniques were used to examine survival rates. Standardized mortality ratios (SMR) with reference to general population (WHO GBD 2016) were estimated. Multiplicative multiple Poisson regression models were used to characterize the association between SMR, IGF-I, and other risk factors associated with mortality risk. RESULTS The study consisted of 2077 subjects who were followed for a median interval of 4.1 years, contributing to 8957 patient-years. Higher on-treatment IGF-I (P = 0.0035), older attained age (P < 0.0001), and longer duration of acromegaly (>10 years) before starting pegvisomant (P = 0.05) were associated with higher mortality rates. In reference to general population rates, higher SMR (1.10, 1.42, and 2.62, at attained age 55 years) were observed with higher serum IGF-I category (SMR trend: 1.44 (44%)/per fold level of IGF-I/ULN (95% CI: 1.10, 1.87), P = 0.0075). SMR increased per year of younger attained age (1.04 (1.02-1.04), P < 0.0001) and were higher for longer disease duration (>10 years) before starting pegvisomant (1.57 (1.02, 2.43), P = 0.042). Serum IGF-I levels within the normal range during pegvisomant therapy were associated with all-cause mortality rates that were indistinguishable from the general population. CONCLUSIONS Higher on-treatment IGF-I, older attained age, and longer duration of acromegaly before starting pegvisomant are associated with higher all-cause mortality rates. Younger patients with uncontrolled acromegaly have higher excess all-cause mortality rates in comparison with older patients.

Abstract
CONTEXT Despite growing evidence that temozolomide (TMZ) therapy is effective for the treatment of aggressive pituitary tumors (APTs) or carcinomas (PCs), individual therapy decisions remain challenging. OBJECTIVE We therefore aimed to report on clinical characteristics leading to initiation of TMZ therapy and to add evidence on TMZ long-term effectiveness. DESIGN AND SUBJECTS Retrospective survey on TMZ treatment in patients with APTs or PCs. TMZ therapy was initiated in 47 patients (22 females) with APTs (n = 34) or PCs (n = 13). Mean age at diagnosis was 45 ± 15 years. The immunohistochemical subtypes were corticotroph (n = 20), lactotroph (n = 18), and nonfunctioning (n = 9) tumors. TMZ therapy started 8 years after initial diagnosis using a standard regimen (median 6 cycles) for the majority of patients. RESULTS Long-term radiological response to TMZ after a median follow-up of 32 months with 4 patients still on TMZ therapy was tumor regression for 9 (20%), stable disease for 8 (17%), and tumor progression for 29 patients (63%) (outcome data available for 46 patients). Progression occurred 16 months after initiation of TMZ. Median estimated progression-free survival was 23 months. Disease stabilization and median progression-free survival did not differ between patients with APTs or PCs. Predictors of tumor response were not identified. Overall, TMZ was well tolerated. CONCLUSION We performed a nationwide survey on TMZ therapy in patients with APTs and PCs. While early response rates to TMZ are promising, long-term outcome is less favorable. Prolonged TMZ administration should be considered. We were not able to confirm previously reported predictors of tumor response to TMZ.

Abstract
CONTEXT Hypertension is a major cardiovascular risk factor related to increased mortality in acromegaly. Surgical cure of acromegaly is associated with improvement in blood pressure levels, however little is known about the effect of pegvisomant (PEGV) treatment in patients with hypertension. This analysis evaluates outcomes in patients with hypertension and acromegaly included in ACROSTUDY. METHODS ACROSTUDY is a global non-interventional surveillance study of long-term treatment with PEGV, monitoring its safety and efficacy. The cohort was retrospectively divided in two subgroups: patients with and without hypertension. Stepwise logistic regression and Kaplan-Meyer analyses were performed for testing predictors of mortality. RESULTS The total cohort included 2,090 patients with acromegaly treated with PEGV who were followed for a median of 6.8 years (range up to 12.1 years). In ACROSTUDY there were 1,344 patients with hypertension (52.3% males). This subgroup was older, had a higher BMI, and higher prevalence of diabetes, hyperlipidemia, and cardiovascular disease (CVD) when compared to patients without hypertension. During ACROSTUDY, 68 deaths were reported in the hypertension cohort, vs 10 in the cohort without hypertension. Both CVD (p<0.0001) and anterior pituitary deficiencies (p=0.0105) at study entry independently predicted mortality in patients with acromegaly and hypertension; Kaplan-Meier analysis confirmed that CVD significantly impairs survival. CONCLUSIONS Hypertension is common in patients with acromegaly and significantly increases mortality, especially when there is concomitant CVD. These data suggest that treatment goals should extend beyond IGF-I normalization, and include optimisation of substitution of pituitary deficiencies and scrutinous screening and treatment of CVD.

Abstract
In an unclear case of Cushing's syndrome, IPSS identifies the origin of ACTH secretion, and together with MRI enables the localization of an ectopic corticotroph adenoma in the parasellar or cavernous sinuses region.

Abstract
OBJECTIVE Parasellar growth is one of the most important prognostic variables of pituitary adenoma surgery, with adenomas regarded as not completely resectable if they invade the cavernous sinus (CS) but potentially curable if they displace CS structures. This study was conducted to correlate surgical treatment options and outcomes to the different biological behaviors (invasion vs displacement) of adenomas with parasellar extension into the superior or inferior CS compartments or completely encasing the carotid artery (Knosp high grades 3A, 3B, and 4). METHODS This was a retrospective cohort analysis of 106 consecutive patients with Knosp high-grade pituitary adenomas with parasellar extension who underwent surgery via a primary endoscopic transsphenoidal approach between 2003 and 2017. Biological tumor characteristics (surgical status of invasiveness and tumor texture, 2017 WHO classification, proliferation rate), extent of resection, and complication rate were correlated with parasellar extension grades 3A, 3B, and 4 on preoperative MRI studies. RESULTS Invasiveness was significantly less common in grade 3A (44%) than in grade 3B (72%, p = 0.037) and grade 4 (100%, p < 0.001) adenomas. Fibrous tumor texture was significantly more common in grade 4 (52%) compared to grade 3A (20%, p = 0.002), but not compared to grade 3B (28%) adenomas. Functioning macroadenomas had a significantly higher rate of invasiveness than nonfunctioning adenomas (91% vs 55%, p = 0.002). Mean proliferation rate assessed by MIB-1 was > 3% in all groups but without significant difference between the groups (grade 3A, 3.2%; 3B, 3.9%; 4, 3.7%). Rates of endocrine remission/gross-total resection were significantly higher in grade 3A (64%) than in grade 3B (33%, p = 0.021) and grade 4 (0%, p < 0.001) adenomas. In terms of complication rates, no significant difference was observed between grades. CONCLUSIONS According to the authors' data, the biological behavior of pituitary adenomas varies significantly between parasellar extension patterns. Adenomas with extension into the superior CS compartment have a lower rate of invasive growth than adenomas extending into the inferior CS compartment or encasing the carotid artery. Consequently, a significantly higher rate of remission can be achieved in grade 3A than in grade 3B and grade 4 adenomas. Therefore, the distinction into grades 3A, 3B, and 4 is of importance for prediction of adenoma invasion and surgical treatment considerations.

Abstract
Background: In healthy subjects, growth hormone (GH) concentrations following an oral glucose suppression test (OGTT) are known to be under the impact of gender, age, BMI an estrogen use. To date, very few data exist on factors influencing nadir GH in patients with acromegaly. Methods: In the present study, we evaluated factors related to nadir GH concentrations during a 2h-75g-OGTT analysing data from 410 OGTTs performed in 134 patients with acromegaly in a tertiary care center. All patients were not receiving any acromegaly-specific medical therapy, 119 OGTTs were performed at the initial disease diagnosis, 281 were performed after at least one pituitary surgery. The relationship between GH supression and IGF-1, morphological data and parameters of lipid and glucose metabolism was tested using uni- and multivariate regression analysis. Results: In the whole cohort (43% males), nadir GH concentrations were neither related to gender, nor to BMI, but positively correlated to fasting GH (P=0.000), IGF-1 (P=0.000), tumour size (P<0.001), plasma glucose (P=0.000), insulin (P=0.000), C-peptide (P=0.000), fasting and OGTT-based indices of insulin secretion and sensitivity, and also to the gonadotropic activity with gonadotropic insufficiency observed in male and female patients with higher disease activity (P=0.000). In addition, nadir GH negatively correlated to age (P=0.001) and HDL-cholesterol concentrations (P=0.003). Only parameters of glucose metabolism (prehepatic beta-cell function, HOMA-insulin resistance index, OGIS-insulin sensitivity index) independently predicted nadir GH concentrations in the whole cohort, as well as in the group of patients with high IGF-1 levels (pre- and postoperative), and also when OGTTs performed in men and women were separately analysed. In OGTTs performed after normalisation of IGF-1 postoperatively, nadir GH remained in a positive relationship to fasting GH and IGF-1, but negatively correlated to all parameters of glucose metabolism, and positively correlated to HDL-cholesterol. Conclusion: In a large single center series, we find that parameters of glucose metabolism are the main direct predictors of nadir GH concentrations in patients with active acromegaly. The relationship between nadir GH and glucose metabolism reflects the diabetogenic effects of GH, and might also impact the cutt off value of nadir GH during OGTT used for the biochemical definition of acromegaly.

Abstract
PURPOSE In Cushing's syndrome, comorbidities often persist after remission of glucocorticoid excess. Here, we aim to identify factors predicting long-term comorbidities in patients with Cushing's syndrome in remission. METHODS In a retrospective cross-sectional study, 118 patients with Cushing's syndrome in remission (52 pituitary, 58 adrenal, 8 ectopic) were followed for a median of 7.9 years (range 2-38) after the last surgery. Associations between baseline anthropometric, metabolic, hormonal parameters at diagnosis, and comorbidities (obesity, diabetes, hyperlipidemia, hypertension, osteoporosis, depression) at last follow-up, were tested by uni- and multivariate regression analysis. RESULTS In patients with manifest comorbidities at diagnosis, remission of Cushing's syndrome resolved diabetes in 56% of cases, hypertension in 36% of cases, hyperlipidaemia in 23%, and depression in 52% of cases. In a multivariate regression analysis, age, fasting glucose, BMI, and the number of comorbidities at diagnosis were positive predictors of the number of long-term comorbidities, while baseline 24-h urinary free cortisol (UFC) negatively correlated with the persistence of long-term comorbidities. The negative relationship between baseline UFC and long-term comorbidities was also found when pituitary and adrenal Cushing's cases were analyzed separately. Baseline UFC was negatively related to the time of exposure to excess glucocorticoids. CONCLUSIONS Long-term comorbidities after remission of Cushing's syndrome depend not only on the presence of classic cardiovascular risk factors (age, hyperglycemia, BMI), but also on the extent of glucocorticoid excess. Lower baseline UFC is associated with a higher number of long-term comorbidities, possibly due to the longer exposure to excess glucocorticoids in milder Cushing's syndrome.

Abstract
BACKGROUND AND AIMS Growth differentiation factor 15 (GDF15) is a strong predictor of cardiovascular morbidity and mortality found to be both marker and target of impaired glucose metabolism. GDF15 increases following glucose administration and is up-regulated in obesity and diabetes. We investigate here the relationship between GDF15 and beta cell function. METHODS AND RESULTS In this cross-sectional study we evaluated GDF15 concentrations in 160 obese subjects (BMI 35-63 kg/m2, age 39.4 ± 18.6 years, m/f 38/122) who underwent a 75 g oral glucose tolerance test (OGTT). Based on the OGTT results, the cohort was divided into two groups: 1) normal fasting glucose and normal glucose tolerance (n = 80), 2) impaired fasting glucose, impaired glucose tolerance or type 2 diabetes (n = 80). The relationship of GDF15 to fasting and OGTT-based dynamic insulin sensitivity and insulin secretion parameters was evaluated. GDF15 was higher in the prediabetes and diabetes groups and correlated with HbA1c, glucose, insulin as well as baseline and dynamic indices of insulin sensitivity and estimated beta cell function. Multiple regression analysis revealed that age, waist-to-height ratio, glomerular filtration rate and prehepatic beta cell function, but not the grade of impairment of glucose metabolism, were independent predictors of GDF15. Subgroup analysis showed that of all parameters of glucose metabolism only C-peptide, fasting prehepatic beta cell function and insulinogenic index remained significantly related to GDF15 in both groups. CONCLUSION We conclude that in patients with severe obesity, GDF15 strongly relates to beta cell function and should be further investigated as a potential therapeutic target and biomarker guiding treatment options.

Abstract
OBJECTIVE Pituitary apoplexy is a rare but potentially life-threatening disorder that occurs in up to 10% of adenomas. Whereas risk factors for the initial hemorrhagic event are well described, there is minor knowledge on clinical symptomatic recurrent pituitary apoplexies. METHODS At the Medical University of Vienna, 76 patients were surgically treated for clinical symptomatic pituitary apoplexy between 1990 and 2017. Four patients (5.3%) suffered multiple pituitary apoplexies after initial surgery. In this retrospective study, neuroradiologic images, clinical data, and intraoperative findings were reviewed for potential risk factors of multiple apoplexies in pituitary adenomas. RESULTS Patients with multiple apoplexies had significantly higher Knosp grading on preoperative imaging (median grade 4), and more frequently observed cavernous sinus invasion intraoperatively (P = 0.01). Consequently, all cases with multiple pituitary apoplexies remained with residual adenoma postoperatively. In cases of residual tumor within the cavernous sinus, recurrent apoplexy occurred in 23.5% of patients. A tumor recurrence/residual was resected significantly earlier in patients with single apoplexy (median 2.2 years) than in patients with multiple apoplexies (median 5.4 years; P = 0.05). Multiple pituitary apoplexies caused significantly greater rates of ophthalmoplegia (75% vs. 14.1%; P = 0.01) and long-term hormone-replacement therapy was necessary in all cases. CONCLUSIONS Cavernous sinus invasion and subtotal resection are high risk factors for multiple apoplexies in pituitary adenomas. Early treatment is recommended for residual tumor in the cavernous sinus to minimize the risk of recurrent apoplexy with subsequent worse clinical outcome.

Abstract
Acromegaly is characterized by chronic overproduction of growth hormone (GH) that leads to insulin resistance, glucose intolerance and, ultimately, diabetes. The GH-induced sustained stimulation of lipolysis plays a major role not only in the development of insulin resistance and prediabetes/diabetes, but also in the reduction of lipid accumulation, making acromegaly a unique case of severe insulin resistance in the presence of reduced body fat. In the present review, we elucidate the effects of GH hypersecretion on metabolic organs, describing the pathophysiology of impaired glucose tolerance in acromegaly, as well as the impact of acromegaly-specific therapies on glucose metabolism. In addition, we highlight the role of insulin resistance in the development of acromegaly-associated complications such as hypertension, cardiac disease, sleep apnea, polycystic ovaries, bone disease, and cancer. Taken together, insulin resistance is an important metabolic hallmark of acromegaly, which is strongly related to disease activity, the development of comorbidities, and might even impact the response to drugs used in the treatment of acromegaly.

Abstract
BACKGROUND & AIMS Obesity is associated with lower breastfeeding rates. The underlying pathophysiological mechanisms are not well-understood, but there is increasing evidence on an association between parameters of maternal glucose metabolism and prolactin concentrations. In this cross-sectional observational study we investigate the relationship between breastfeeding, maternal obesity, and maternal glucose metabolism postpartum with beta cell function as a primary outcome measure. METHODS We investigated 106 women (44% obese) prospectively recruited during the pregnancy, who underwent a 75 g - 2 h oral glucose tolerance test (OGTT) between the 3rd and 5th months postpartum. At this time point, we tested the relationship between breastfeeding status, maternal prolactin concentrations, maternal obesity, and fasting and dynamic indices of glucose metabolism using multivariate logistic regression in a post hoc analysis of prospective observational data. RESULTS During the study visit at a mean of 122 (SE 9.3) days after delivery, 47% of obese women and 68% of non-obese women were breastfeeding (p < 0.05). Lactation and higher prolactin concentrations were associated with lower prepregnancy weight and lower postpartum insulin concentrations. Prehepatic beta-cell function was decreased in both obese (mean (SD); 0.16 (0.04) vs. 0.19 (0.05), p < 0.05) and non-obese (0.12 (0.05) vs. 0.16 (0.06), p < 0.01), lactating women. Obese lactating women have significantly lower first (1135.1 (306.7) pmol/L vs. 1517.3 (475.8) pmol/L, p < 0.01) and second phase insulin secretion (mean (SD), 300.2 (70.7) pmol/L vs. 393.1 (115.5) pmol/L, p < 0.01) as shown by Stumvoll indices when comparing to obese non-lactating women. Prehepatic beta-cell function and Stumvoll 1st phase insulin secretion index, but not BMI, were independently and negatively associated with breastfeeding and circulating prolactin concentrations. CONCLUSIONS Beta-cell function during lactation relates to breastfeeding and circulating prolactin concentrations independently of obesity. The well-known positive effects of lactation on maternal and offspring outcomes might reflect a causative relationship of higher breastfeeding rates in metabolically healthier women.

Abstract
The prevalence of vitamin D deficiency in intensive care units ranges typically between 40 and 70%. There are many reasons for being or becoming deficient in the ICU. Hepatic, parathyroid and renal dysfunction additionally increases the risk for developing vitamin D deficiency. Moreover, therapeutic interventions like fluid resuscitation, dialysis, surgery, extracorporeal membrane oxygenation, cardiopulmonary bypass and plasma exchange may significantly reduce vitamin D levels. Many observational studies have consistently shown an association between low vitamin D levels and poor clinical outcomes in critically ill adults and children, including excess mortality and morbidity such as acute kidney injury, acute respiratory failure, duration of mechanical ventilation and sepsis. It is biologically plausible that vitamin D deficiency is an important and modifiable contributor to poor prognosis during and after critical illness. Although vitamin D supplementation is inexpensive, simple and has an excellent safety profile, testing for and treating vitamin D deficiency is currently not routinely performed. Overall, less than 800 patients have been included in RCTs worldwide, but the available data suggest that high-dose vitamin D supplementation could be beneficial. Two large RCTs in Europe and the United States, together aiming to recruit >5000 patients, have started in 2017, and will greatly improve our knowledge in this field. This review aims to summarize current knowledge in this interdisciplinary topic and give an outlook on its highly dynamic future.

A mono-feature fuzzy index that evaluates the stress level from one feature extracted from ECG or GSR is presented. It is build using several measures of the feature recorded when the subject is at rest. The mono-feature fuzzy index can be merged in a multi-feature stress index without any tuning. It can be used to select relevant features and to detect stress. The performance of the stress index is analyzed on a data set made of 160 time periods of time when 20 subjects had to perform stressful tasks and corresponding control tasks. The stress was induced by 4 different tasks. The performances reached are 72% of correctly classified time periods in stress and no stress situations. Interesting conclusions could also be made on the tasks ability to induce stress.

Abstract
Growth hormone (GH) is not approved for use during conception and pregnancy. Nevertheless, data from the clinical care practice reveal that most women concieve on GH replacement therapy (GHRT), and more than half continue on GHRT also during pregnancy. GH stimulates the hypothalamic-pituitary-gonadal axis at all levels, and there is evidence that GH deficiency impacts the morphology of reproductive organs, onset of puberty, ovarian function and fertility. Patients with hypopituitarism often conceive using assisted reproductive techniques and several studies support the benefit of GH supplementation for achieving fertility in women with GH deficiency. During gestation the GH system is regulated by the placental growth hormone, which increases continuously with the growth of placenta and stimulates maternal IGF-1 levels, leading to a concomitant decline in pituitary GH secretion. GHRT regimens that aim to mimic the pathophysiology of GH/IGF-1 concentrations during pregnancy continue GHRT during the first trimester, gradually reduce GH dose during the second trimester and stopp GHRT at the beginning of the third trimester. Pregnancy outcomes were not found to be related to GHRT treatment patterns during pregnancy, but female patients with childhood-onset hypopituitarism have lower fertility rates and less positive pregnancy outcomes. Although current guidelines recommend against GHRT during pregnancy, GHRT might be needed for achieving fertility and satisfactory pregnancy outcomes are reported following the decision of patients and physicians for adapting the GHRT dose during pregnancy.

Abstract
PURPOSE Knowledge of biological behavior is crucial for clinical management of functioning pituitary macroadenomas. For recurrent cases unresponsive to standard treatment, temozolomide (TMZ) has been used as a therapeutic alternative. MGMT (O6-methyl-guanine-DNA methyltransferase) and MSH6 (mutS homolog 6) immunoexpression have been linked to the response to TMZ treatment and MGMT immunoexpression has been additionally linked to early recurrence of non-functioning pituitary adenomas. The aim of this study was to assess the prognostic value of MGMT and MSH6 immunoexpression for aggressive functioning pituitary adenomas. METHODS The study cohort comprised a single center series of 76 patients who underwent an operation for functioning pituitary macroadenoma. We retrospectively compared 38 patients with postoperative persistent or recurrent disease with another set of 38 patients who were in endocrine remission. RESULTS Low-to-moderate MGMT immunoexpression (<50%) was significantly more frequent in the group with persistent/recurrent disease than in cases of endocrine remission (66 vs. 21%, p < 0.001). Furthermore, adenomas with low-to-moderate MGMT immunoexpression were significantly more often recurrent (76 vs. 30%, p < 0.001) and invasive (64 vs. 28%, p = 0.002). CONCLUSION In our series, low-to-moderate MGMT immunoexpression was the only marker that significantly correlated with surgical invasiveness and recurrence in functioning pituitary macroadenomas. Therefore, in the future, MGMT status may be considered an additional marker for understanding the biological behavior of pituitary adenomas.

Abstract
B-type natriuretic peptide (BNP) is a hormone released by the heart in response to volume load and exerts natriuretic properties. It is clinically used as a diagnostic and prognostic biomarker and investigated as a pharmacological agent in the therapy of heart failure. Here we investigate the changes in pituitary, adrenal, and thyroid hormones in response to BNP administration in a randomized single-blinded crossover study conducted in ten healthy men aged 21–29 yr. Participants received in two study sessions a continuous intravenous infusion during 4 h (once placebo and once 3 pmol·kg−1·min−1 BNP) and remained in supine position throughout the study. Circulating concentrations of pituitary, adrenal, and thyroid hormones, heart rate, and blood pressure were measured at baseline and hourly afterwards. BNP prevented the physiological decrease in cortisol during the late morning hours leading to elevated serum cortisol levels ( P = 0.022) and increased circulating epinephrine and norepinephrine concentrations ( P = 0.018 and P = 0.036, respectively). These hormone changes were accompanied by an increase in heart rate ( P = 0.019) but no differences in blood pressure. Taken together, the impact of BNP on the endocrine system extends beyond the well-known inhibition of the renin-angiotensin-aldosterone system and includes increased adrenergic activity and cortisol concentrations. This neuroendocrine activation might impact the outcome of therapeutical BNP administrations and should be further investigated in conditions associated with increased BNP secretion. NEW & NOTEWORTHY The heart hormone B-type natriuretic peptide (BNP) is increased in patients with heart failure, where it is thought to have beneficial effects by reducing the preload. Here we report that intravenous administration of BNP in men leads to increases in adrenal hormones cortisol, epinephrine, and norepinephrine. Cortisol and catecholamine levels are independent predictors of increased cardiovascular mortality risk; therefore, drugs targeting the BNP system should be evaluated regarding their effects on the neuroendocrine activation accompanying heart failure.

Abstract
OBJECTIVE Growth differentiation factor 15 (GDF15) is a cardiovascular biomarker belonging to the transforming growth factor-β superfamily. Increased GDF15 concentrations are associated with insulin resistance, diabetes and obesity. We investigated the physiological effects of meal composition and obesity on the regulation of systemic GDF15 levels. DESIGN Lean (n = 8) and obese (n = 8) individuals received a carbohydrate- or fat-rich meal, a 75 g oral glucose load (OGTT) or short-term fasting. OGTTs were performed in severely obese patients (n = 6) pre- and post-bariatric surgery. METHODS Circulating serum GDF15 concentrations were studied in lean and obese individuals in response to different meals, OGTT or short-term fasting, and in severely obese patients pre- and post-bariatric surgery. Regulation of GDF15 mRNA levels and protein release were evaluated in the human hepatic cell line HepG2. RESULTS GDF15 concentrations steadily decrease during short-term fasting in lean and obese individuals. Carbohydrate- and fat-rich meals do not influence GDF15, whereas an OGTT leads to a late increase in GDF15 levels. The positive effect of OGTT on GDF15 levels is also preserved in severely obese patients, pre- and post-bariatric surgery. We further studied the regulation of GDF15 mRNA levels and protein release in HepG2, finding that glucose and insulin independently stimulate both GDF15 transcription and secretion. CONCLUSION In summary, high glucose and insulin peaks upregulate GDF15 transcription and release. The nutrient-induced increase in GDF15 levels depends on rapid glucose and insulin excursions following fast-digesting carbohydrates, but not on the amount of calories taken in.

Abstract
BACKGROUND Diabetes has been linked epidemiologically to increased cancer incidence and mortality. Growth differentiation factor 15 (GDF-15) is increased in patients with diabetes and has recently been linked to the occurrence of cancer. We investigated whether circulating GDF-15 concentrations can predict the incidence of malignant diseases in a diabetic patient cohort already facing increased risk for cancer. METHODS We prospectively enrolled a total of 919 patients with type 2 diabetes and no history of malignant disease, who were clinically followed up for 60 months. GDF-15, N-terminal pro-B-type natriuretic peptide and troponin T were measured at baseline; an additional 4 cardiovascular biomarkers were determined for a subpopulation (n = 259). Study end point was defined as the first diagnosis of any type of cancer during the follow-up period. RESULTS During a median follow-up of 60 months, 66 patients (7.2%) were diagnosed with cancer. Baseline circulating GDF-15 concentrations were higher in patients that developed cancer over the follow-up period when compared to cancer-free patients. Increased GDF-15 concentrations were significantly associated with cancer incidence [crude hazard ratio (HR) per 1-IQR (interquartile range) increase 2.13, 95% CI 1.53-2.97, P < 0.001]. This effect persisted after multivariate adjustment with an adjusted HR of 1.86 (95% CI 1.22-2.84; P = 0.004). Among the 4 additionally tested cardiovascular markers in the subpopulation, only troponin T and C-terminal proendothelin-1 showed a significant association with future cancer incidence with unadjusted HRs of 1.71 (95% CI 1.28-2.28, P < 0.001) and 1.68 (95% CI 1.02-2.76, P = 0.042), respectively. CONCLUSIONS Increased circulating concentrations of GDF-15 are associated with increased cancer incidence in patients with type 2 diabetes.
