Abstract
Abstract
CRN04894 is a potent orally bioavailable MC2R (adrenal cortex specific ACTH receptor) antagonist (Kb=0.34 nM) that is >1000-fold selective for MC2R over other melanocortin receptor subtypes. In rats receiving continuous administration of ACTH via subcutaneously implanted osmotic pumps, oral administration of CRN04894 over 7 days has previously been shown to result in dose-dependent suppression of basal and ACTH stimulated corticosterone levels. This compound is in clinical development for the treatment of diseases of ACTH excess including congenital adrenal hyperplasia (CAH) and Cushing's Disease.
We report initial results from a randomized double-blinded, placebo-controlled single ascending dose study evaluating the safety, pharmacokinetics and pharmacodynamics of CRN04894 in 39 healthy volunteers. After an overnight fast, single doses of CRN04894 were administered at approximately 8 am, 2 hours prior to an IV bolus of ACTH 1-24 (cosyntropin). Serial cortisol over 600 minutes and pharmacokinetics over 168 hours post CRN04894 dose were measured. Two different challenge doses of ACTH 1-24 were studied: 250 μg (supra-pharmacological) and 1 μg (comparable to ACTH concentrations encountered in CAH and Cushing's Disease).
CRN04894 was rapidly orally absorbed (median tmax 0.5-1.5 hour), and demonstrated a dose dependent increase in systemic exposure, with an apparent terminal elimination t1/2 of approximately 20 hours.
Unstimulated (basal) cortisol measured 2 hours after CRN04894 administration fell in a dose-dependent manner, resulting in reduction near the theoretical maximum with the 80 mg dose cohort (-56.1% [SEM 4.0%, n=12] vs +17.4% in placebo [SEM=18.1%, n=9]). Dose-dependent cortisol suppression following a supra-pharmacological ACTH-stimulated (250 μg) was also observed, with a 41% reduction in the area under the curve (AUC60-600min) post-stimulation at the 80 mg dose. Furthermore, a single dose of 80 mg of CRN04894 reduced the cortisol response (AUC15-120 min) to a disease relevant 1 μg ACTH challenge by 48%, maintaining cortisol concentrations within the normal range seen prior to dosing in a basal unstimulated state. Single doses of CRN04894 were well tolerated with no need for glucocorticoid supplementation. All adverse events (AEs) were considered mild or moderate and there were no serious AEs.
The data from this single-dose, proof-of-concept study show that MC2R antagonist CRN04894 was well tolerated after oral delivery in healthy volunteers and demonstrated dose-dependent increases in exposure with lowering of basal and ACTH-stimulated cortisol secretion, including in the presence of disease relevant excess ACTH exposure. Multiple ascending dose evaluations are underway in anticipation of studies in patients with diseases of ACTH excess.

Abstract
INTRODUCTION Surgical remission for acromegaly is dependent on a number of factors including tumour size, invasiveness, and surgical expertise. We studied the value of early post-operative growth hormone (GH) level as a predictor of outcome and to guide early surgical re-exploration for residual disease in patients with acromegaly. METHODS Patients with acromegaly undergoing first-time endoscopic transsphenoidal surgery between 2005 and 2015, in 2 regional neurosurgical centres, were studied. Insulin-like growth factor-1 (IGF-1), basal GH (i.e., sample before oral glucose), and GH nadir on oral glucose tolerance test (OGTT) were tested at various time points, including 2-5 days post-operatively. Definition of disease remission was according to the 2010 consensus statement (i.e., GH nadir <0.4 μg/L during an OGTT and normalized population-matched IGF-1). Forward stepwise logistic regression was used to determine factors associated with remission. RESULTS We investigated 81 consecutive patients with acromegaly, 67 (83%) of which had macroadenomas and 22 (27%) were noted to be invasive at surgery. Mean follow-up was 44 ± 25 months. Overall, surgical remission was achieved in 55 (68%) patients at final follow-up. On univariate analysis, the remission rates at the end of the study period for patients with early post-operative GH nadir on OGTT of <0.4 (N = 43), between 0.4 and 1 (N = 28), and >1 μg/L (N = 8) were 88, 54, and 20%, respectively. Similar results were seen with basal GH on early post-operative OGTT. On multivariate regression analysis, pre-operative IGF-1 (odds ratio of 13.1) and early post-operative basal GH (odds ratio of 5.0) and GH nadir on OGTT (odds ratio of 6.8) were significant predictors of residual disease. Based on a raised early GH nadir and post-operative MR findings, 10 patients underwent early surgical re-exploration. There was reduction in post-operative GH levels in 9 cases, of which 5 (50%) achieved long-term remission. There was an increased risk of new pituitary hormone deficiencies in patients having surgical re-exploration compared to those having a single operation (60 vs. 14%). CONCLUSIONS An early post-operative basal GH and GH nadir on OGTT are reliable predictors of long-term disease remission. It can be used to guide patients for early surgical re-exploration for residual disease, although there is increased risk of hypopituitarism.

Abstract
The WHO Classification of Endocrine Tumours designates pituitary neoplasms as adenomas. A proposed nomenclature change to pituitary neuroendocrine tumors (PitNETs) has been met with concern by some stakeholder groups. The Pituitary Society coordinated the Pituitary Neoplasm Nomenclature (PANOMEN) workshop to address the topic. Experts in pituitary developmental biology, pathology, neurosurgery, endocrinology, and oncology, including representatives nominated by the Endocrine Society, European Society of Endocrinology, European Neuroendocrine Association, Growth Hormone Research Society, and International Society of Pituitary Surgeons. Clinical epidemiology, disease phenotype, management, and prognosis of pituitary adenomas differ from that of most NETs. The vast majority of pituitary adenomas are benign and do not adversely impact life expectancy. A nomenclature change to PitNET does not address the main challenge of prognostic prediction, assigns an uncertain malignancy designation to benign pituitary adenomas, and may adversely affect patients. Due to pandemic restrictions, the workshop was conducted virtually, with audiovisual lectures and written précis on each topic provided to all participants. Feedback was collated and summarized by Content Chairs and discussed during a virtual writing meeting moderated by Session Chairs, which yielded an evidence-based draft document sent to all participants for review and approval. There is not yet a case for adopting the PitNET nomenclature. The PANOMEN Workshop recommends that the term adenoma be retained and that the topic be revisited as new evidence on pituitary neoplasm biology emerges.

Abstract
The 13th Acromegaly Consensus Conference was held in November 2019 in Fort Lauderdale, Florida, and comprised acromegaly experts including endocrinologists and neurosurgeons who considered optimal approaches for multidisciplinary acromegaly management. Focused discussions reviewed techniques, results, and side effects of surgery, radiotherapy, and medical therapy, and how advances in technology and novel techniques have changed the way these modalities are used alone or in combination. Effects of treatment on patient outcomes were considered, along with strategies for optimizing and personalizing therapeutic approaches. Expert consensus recommendations emphasize how best to implement available treatment options as part of a multidisciplinary approach at Pituitary Tumor Centers of Excellence.

Abstract
CONTEXT Appropriate management of adrenal insufficiency (AI) in pregnancy can be challenging due to the rarity of the disease and lack of evidence-based recommendations to guide glucocorticoid and mineralocorticoid dosage adjustment. OBJECTIVE Multicenter survey on current clinical approaches in managing AI during pregnancy. DESIGN Retrospective anonymized data collection from 19 international centers from 2013 to 2019. SETTING AND PATIENTS 128 pregnancies in 113 women with different causes of AI: Addison disease (44%), secondary AI (25%), congenital adrenal hyperplasia (25%), and acquired AI due to bilateral adrenalectomy (6%). RESULTS Hydrocortisone (HC) was the most commonly used glucocorticoid in 83% (97/117) of pregnancies. Glucocorticoid dosage was increased at any time during pregnancy in 73/128 (57%) of cases. In these cases, the difference in the daily dose of HC equivalent between baseline and the third trimester was 8.6 ± 5.4 (range 1-30) mg. Fludrocortisone dosage was increased in fewer cases (7/54 during the first trimester, 9/64 during the second trimester, and 9/62 cases during the third trimester). Overall, an adrenal crisis was reported in 9/128 (7%) pregnancies. Cesarean section was the most frequent mode of delivery at 58% (69/118). Fetal complications were reported in 3/120 (3%) and minor maternal complications in 15/120 (13%) pregnancies without fatal outcomes. CONCLUSIONS This survey confirms good maternal and fetal outcome in women with AI managed in specialized endocrine centers. An emphasis on careful endocrine follow-up and repeated patient education is likely to have reduced the risk of adrenal crisis and resulted in positive outcomes.

Abstract
Context: Adrenal insufficiency (AI) is associated with reduced life expectancy and increased morbidity even after glucocorticoid replacement therapy. Aim Our aim was to assess the co-morbid burden of AI in a United Kingdom-based population. Methods We retrospectively studied patients diagnosed between 1996 and 2014 (minimum disease duration 12 months) with primary (PAI; n=55 [23 females]; CAH excluded) and secondary AI (SAI; n=79 [29 females]; Cushing’s syndrome and acromegaly excluded) using an electronic patient database (n=352000) in North West England. Patients with AI were identified by diagnostic codes and glucocorticoid prescriptions. Each patient with PAI or SAI was matched to non-AI patients with the same gender and date of birth (control cohort n=35172). Outcome measures were change in weight, prevalence of co-morbid illness (type 2 diabetes [T2D], prediabetes, hypertension, cardiovascular disease [CVD] and osteoporosis) and hospital admissions during the study period. Results In PAI, 91% of patients were treated with hydrocortisone (mean dose 23 ±8 mg) and 9% with prednisolone (mean dose 3 ±2 mg). In SAI, 94% of patients were treated with hydrocortisone (mean dose 18 ±8 mg) and 5% with prednisolone (mean dose 6 ±3 mg). The annual weight change compared to controls was significantly higher in PAI (median 1.16 kg [0.15-2.96], vs -0.01 kg [-0.49 – 0.41]; P=0.001) and SAI (median 0.55 kg [-1.49 – 1.57] vs median -0.47 kg [-0.99 – 0.32]; P=0.045). When comparing the weight at the time of diagnosis to the last available weight in the study period, a higher proportion of patients were within the overweight/obese category (BMI ≥ 25 kg/m2) for PAI (38% [baseline] vs 70% [study end]; P=0.028) but not SAI (85% [baseline] vs 73% [study end]; P=0.327) and controls (65% [baseline] vs 56% [study end]; P=0.218). For PAI, the prevalence of prediabetes (22% vs 10%), T2D (9% vs 5%), hypertension (38% vs 30%) and CVD (9% vs 5%) was significantly (p<0.05) different to controls. For SAI, the prevalence of prediabetes (27% vs 19%), T2D (20% vs 10%), hypertension (68% vs 53%) was significantly different (P<0.05) to controls. There were no differences in the prevalence of CVD between patients with SAI and controls (10% vs 10%; P=0.87). The risk ratio for osteoporosis to controls was 4.00 (P=0.025) for PAI and 4.33 (P=0.018) for SAI. The ratio (to controls) of the number of acute hospital admissions was higher in both PAI (5:1; P=0.011) and SAI (7:1; P=0.017). Conclusion PAI and SAI are both associated with a higher prevalence of co-morbid disease and increased hospital admissions suggesting a greater health burden. The excessive glucocorticoid replacement dose (especially in PAI) may have influenced the adverse metabolic changes observed. Statement of Support ViroPharma, now part of Shire, Lexington, MA, USA provided financial support but were not involved in the study design or interpretation of the data.

Abstract
AIMS To estimate a preference-based single index for the disease-specific instrument (AcroQoL) by mapping it onto the EQ-5D to assist in future economic evaluations. MATERIALS AND METHODS A sample of 245 acromegaly patients with AcroQoL and EQ-5D scores was obtained from three previously published European studies. The sample was split into two: one sub-sample to construct the model (algorithm construction sample, n = 184), and the other one to confirm it (validation sample, n = 61). Various multiple regression models including two-part model, tobit model, and generalized additive models were tested and/or evaluated for predictive ability, consistency of estimated coefficients, normality of prediction errors, and simplicity. RESULTS Across these studies, mean age was 50-60 years and the proportion of males was 36-59%. At overall level the percentage of patients with controlled disease was 37.4%. Mean (SD) scores for AcroQoL Global Score and EQ-5D utility were 62.3 (18.5) and 0.71 (0.28), respectively. The best model for predicting EQ-5D was a generalized regression model that included the Physical Dimension summary score and categories from questions 9 and 14 as independent variables (Adj. R2 = 0.56, with mean absolute error of 0.0128 in the confirmatory sample). Observed and predicted utilities were strongly correlated (Spearman r = 0.73, p < .001) and paired t-Student test revealed non-significant differences between means (p > .05). Estimated utility scores showed a minimum error of ≤10% in 45% of patients; however, error increased in patients with an observed utility score under 0.2. The model's predictive ability was confirmed in the validation cohort. LIMITATIONS AND CONCLUSIONS A mapping algorithm was developed for mapping of AcroQoL to EQ-5D, using patient level data from three previously published studies, and including validation in the confirmatory sub-sample. Mean (SD) utilities index in this study population was estimated as 0.71 (0.28). Additional research may be needed to test this mapping algorithm in other acromegaly populations.

Abstract
OBJECTIVE The Growth Hormone Research Society (GRS) convened a Workshop in 2017 to evaluate clinical endpoints, surrogate endpoints and biomarkers during GH treatment of children and adults and in patients with acromegaly. PARTICIPANTS GRS invited 34 international experts including clinicians, basic scientists, a regulatory scientist and physicians from the pharmaceutical industry. EVIDENCE Current literature was reviewed and expert opinion was utilized to establish the state of the art and identify current gaps and unmet needs. CONSENSUS PROCESS Following plenary presentations, breakout groups discussed questions framed by the planning committee. The attendees re-convened after each breakout session to share the group reports. A writing team compiled the breakout session reports into a document that was subsequently discussed and revised by participants. This was edited further and circulated for final review after the meeting. Participants from pharmaceutical companies were not part of the writing process. CONCLUSIONS The clinical endpoint in paediatric GH treatment is adult height with height velocity as a surrogate endpoint. Increased life expectancy is the ideal but unfeasible clinical endpoint of GH treatment in adult GH-deficient patients (GHDA) and in patients with acromegaly. The pragmatic clinical endpoints in GHDA include normalization of body composition and quality of life, whereas symptom relief and reversal of comorbidities are used in acromegaly. Serum IGF-I is widely used as a biomarker, even though it correlates weakly with clinical endpoints in GH treatment, whereas in acromegaly, normalization of IGF-I may be related to improvement in mortality. There is an unmet need for novel biomarkers that capture the pleiotropic actions of GH in relation to GH treatment and in patients with acromegaly.

Abstract
Checkpoint inhibitors, such as ipilimumab and pembrolizumab, have transformed the prognosis for patients with advanced malignant melanoma and squamous non-small-cell lung cancer, and their use will only expand as experience is gained in a variety of other malignancies, for instance, renal and lymphoma. As the use of checkpoint inhibitors increases, so too will the incidence of their unique side effects, termed immune-related adverse events (irAEs), which can affect dermatological, gastrointestinal, hepatic, endocrine and other systems. Nivolumab is a monoclonal antibody that blocks the human programmed death receptor-1 ligand (PD-L1) found on many cancer cells and is licensed for the treatment of advanced malignant melanoma. We describe the first case of nivolumab-induced adrenalitis resulting in primary adrenal failure presenting with hyponatraemia in a 43-year-old man with malignant melanoma. The case highlights the potentially life-threatening complications of checkpoint inhibitors and the need for patient education and awareness of irAEs among the wider clinical community because such side effects require prompt recognition and treatment. LEARNING POINTS Nivolumab can cause primary adrenal insufficiency.Not all cases of hyponatraemia in patients with malignancy are due to SIADH.Any patient on a checkpoint inhibitor becoming unwell should have serum cortisol urgently measured and if in doubt hydrocortisone therapy should be initiated.Although hyponatraemia can occur in patients with ACTH deficiency, the possibility of primary adrenal failure should also be considered and investigated by measurement of renin, aldosterone and ACTH.Patients receiving checkpoint inhibitors require education on the potential risks of hypocortisolaemia.PET imaging demonstrated bilateral increased activity consistent with an autoimmune adrenalitis.

Abstract
Circulating insulin-like growth factor-1 (IGF-1) is increasingly being used as a screening test and in ongoing monitoring of treated acromegaly. We here present three cases of women (two of whom were on the oestrogen containing contraceptive pill at the time of presentation) who had normal circulating IGF-1 and no overt clinical features of acromegaly at the time of their pituitary surgery. Postoperatively, all were confirmed to have growth hormone excess in keeping with the presence of active somatotroph pituitary adenomas. We suggest that for optimal patient management, formal evaluation of growth hormone status with oral glucose tolerance testing should ideally be performed on all individuals for whom pituitary surgery is planned.

Abstract
BACKGROUND A novel oral octreotide formulation was tested for efficacy and safety in a phase III, multicenter, open-label, dose-titration, baseline-controlled study in patients with acromegaly. METHODS We enrolled 155 complete or partially controlled patients (IGF-1 <1.3 × upper limit of normal [ULN], and 2-h integrated GH <2.5 ng/mL) receiving injectable somatostatin receptor ligand (SRL) for ≥ 3 months. Subjects were switched to 40 mg/d oral octreotide capsules (OOCs), and the dose escalated to 60 and then up to 80 mg/d to control IGF-1. Subsequent fixed doses were maintained for a 7-month core treatment, followed by a voluntary 6-month extension. RESULTS Of 151 evaluable subjects initiating OOCs, 65% maintained response and achieved the primary endpoint of IGF-1 <1.3 × ULN and mean integrated GH <2.5 ng/mL at the end of the core treatment period and 62% at the end of treatment (up to 13 mo). The effect was durable, and 85 % of subjects initially controlled on OOCs maintained this response up to 13 months. When controlled on OOCs, GH levels were reduced compared to baseline, and acromegaly-related symptoms improved. Of 102 subjects completing the core treatment, 86% elected to enroll in the 6-month extension. Twenty-six subjects who were considered treatment failures (IGF-1 ≥ 1.3 × ULN) terminated early, and 23 withdrew for adverse events, consistent with those known for octreotide or disease related. CONCLUSIONS OOC, an oral therapeutic peptide, achieves efficacy in controlling IGF-1 and GH after switching from injectable SRLs for up to 13 months, with a safety profile consistent with approved SRLs. OOC appears to be effective and safe as an acromegaly monotherapy.

Abstract
INTRODUCTION Surgical remission rates for acromegaly vary and are dependent on the tumour morphology, biochemical definition of disease remission and surgical expertise. A previous report from the Manchester region in 1998 reported an overall surgical remission rate of 27% using accepted criteria for biochemical remission at the time. The establishment of the 2010 Consensus guidelines further tightens biochemical criteria for remission. This report aims to assess the impact of establishing a specialist pituitary surgery service in Manchester in 2005, with reduced surgeon numbers on the remission rates for acromegaly surgery. METHODS Patients with acromegaly undergoing first time endoscopic transsphenoidal surgery between 2005 and 2010 were studied. Surgery was performed by a single surgeon. Review of a prospectively collected acromegaly surgery database was performed with documentation of pre- and postoperative biochemical tests [oral glucose tolerance test (oGTT) and IGF-1], as well as clinical, pathological and radiological data. Definition of disease remission was according to the 2010 Consensus criteria (GH nadir <0·4 μg/l following an oGTT and normalized population matched IGF-1). RESULTS There were 43 consecutive patients with acromegaly, with 13 (30%) microadenomas and 12 (28%) invasive adenomas. Overall, surgical remission was achieved in 29 (67%) patients. The remission rates were similar between micro (77%), macro (63%) and giant (67%) adenomas. There were nonsignificant trends towards higher remission rates for noninvasive tumours compared with invasive tumours (74%vs 50%) and for patients with a preoperative GH nadir <10 μg/l (73%vs 54%) and IGF-1 standard deviation score <15 (72%vs 54%). CONCLUSIONS Remission rates for acromegaly surgery have improved following establishment of a specialist surgical service, with a reduction in surgeon numbers. Endoscopic trans-sphenoidal surgery remains an effective first-line treatment for achieving biochemical remission in acromegaly, despite the introduction of the more stringent 2010 consensus guidelines.

Abstract
BACKGROUND Pharmacoepidemiological surveys provide a valuable contribution to the continued monitoring of drug-related effects in patients with rare disorders. One of the earliest examples of this type of survey is KIGS (Pfizer International Growth Study Database), which has monitored the safety and effectiveness of growth hormone (GH) therapy in GH-deficient children since its inception in 1987. Following closely in the footsteps of KIGS is KIMS (Pfizer International Metabolic Database). As of 2009, KIMS has been collecting data on the long-term safety and clinical outcomes of GH replacement in GH-deficient adults for 15 years. Approximately 5 years ago, the ACROSTUDY database was established to monitor the long-term safety and effectiveness of pegvisomant in patients with acromegaly. CONCLUSIONS By collecting data on the treatment of relatively rare conditions in routine clinical practice, pharmacoepidemiological surveys such as KIMS and ACROSTUDY provide valuable information on the safety and effectiveness of treatment with GH replacement and pegvisomant in the real world.

Abstract
BACKGROUND Early diagnosis of a number of endocrine diseases is theoretically possible by the examination of facial photographs. One of these is acromegaly. If acromegaly were found, early in the course of the disease, morbidity would be lessened and cures more likely. OBJECTIVES, DESIGN, PATIENTS, MEASUREMENTS: Our objective was to develop a computer program which would separate 24 facial photographs, of patients with acromegaly, from those of 25 normal subjects. The key to doing this was to use a previously developed database that consisted of three-dimensional representations of 200 normal person's heads (SIGGRAPH '99 Conference Proceedings, 1999). We transformed our 49, two-dimensional photos into three-dimensional constructs and then, using the computer program, attempted to separate them into those with and without the features of acromegaly. We compared the accuracy of the computer to that of 10 generalist physicians. A second objective was to examine, by a subjective analysis, the features of acromegaly in the normal subjects of our photographic database. RESULTS The accuracy of the computer model was 86%; the average of the 10 physicians was 26%. The worst individual physician, 16%, the best, 90%. The faces of 200 normal subjects, the original faces in the database, could be divided into four groups, averaged by computer, from those with fewer to those with more features of acromegaly. CONCLUSIONS The present computer model can sort photographs of patients with acromegaly from photographs of normal subjects and is much more accurate than the sorting by practicing generalists. Even normal subjects have some of the features of acromegaly. Screening with this approach can be improved with automation of the procedure, software development and the identification of target populations in which the prevalence of acromegaly may be increased over that in the general population.

Abstract
To determine whether peer-reviewed consensus statements have changed clinical practice, we surveyed acromegaly care in specialist centers across the globe, and determined the degree of adherence to published consensus guidelines on acromegaly management. Sixty-five acromegaly experts who participated in the 7th Acromegaly Consensus Workshop in March 2009 responded. Results indicated that the most common referring sources for acromegaly patients were other endocrinologists (in 26% of centers), neurosurgeons (25%) and primary care physicians (21%). In sixty-nine percent of patients, biochemical diagnoses were made by evaluating results of a combination of growth hormone (GH) nadir/basal GH and elevated insulin like growth factor-I (IGF-I) levels. In both Europe and the USA, neurosurgery was the treatment of choice for GH-secreting microadenomas and for macroadenomas with compromised visual function. The most widely used criteria for neurosurgical outcome assessment were combined measurements of IGF-I and GH levels after oral glucose tolerance test (OGTT) 3 months after surgery. Ninety-eight percent of respondents stated that primary treatment with somatostatin receptor ligands (SRLs) was indicated at least sometime during the management of acromegaly patients. In nearly all centers (96%), the use of pegvisomant monotherapy was restricted to patients who had failed to achieve biochemical control with SRL therapy. The observation that most centers followed consensus statement recommendations encourages the future utility of these workshops aimed to create uniform management standards for acromegaly.

Abstract
OBJECTIVE The Acromegaly Consensus Group met in April 2009 to revisit the guidelines on criteria for cure as defined in 2000. PARTICIPANTS Participants included 74 neurosurgeons and endocrinologists with extensive experience of treating acromegaly. EVIDENCE/CONSENSUS PROCESS: Relevant assays, biochemical measures, clinical outcomes, and definition of disease control were discussed, based on the available published evidence, and the strength of consensus statements was rated. CONCLUSIONS Criteria to define active acromegaly and disease control were agreed, and several significant changes were made to the 2000 guidelines. Appropriate methods of measuring and achieving disease control were summarized.

Abstract
OBJECTIVE Patients in remission from Cushing's disease (CD) have many clinical features that are difficult to distinguish from those of concomitant GH deficiency (GHD). In this study, we evaluated the features of GHD in a large cohort of controlled CD patients, and assessed the effect of GH treatment. DESIGN AND METHODS Data were obtained from KIMS, the Pfizer International Metabolic Database. A retrospective cross-sectional comparison of background characteristics in unmatched cohorts of patients with CD (n=684, 74% women) and nonfunctioning pituitary adenoma (NFPA; n=2990, 39% women) was conducted. In addition, a longitudinal evaluation of 3 years of GH replacement in a subset of patients with controlled CD (n=322) and NFPA (n=748) matched for age and gender was performed. RESULTS The cross-sectional study showed a significant delay in GHD diagnosis in the CD group, who had a higher prevalence of hypertension, fractures, and diabetes mellitus. In the longitudinal, matched study, the CD group had a better metabolic profile but a poorer quality of life (QoL) at baseline, which was assessed with the disease-specific questionnaire QoL-assessment of GHD in adults. After 3 years of GH treatment (mean dose at 3 years 0.39 mg/day in CD and 0.37 mg/day in NFPA), total and low-density lipoprotein cholesterol decreased, while glucose and HbAlc increased. Improvement in QoL was observed, which was greater in the CD group (-6 CD group versus -5 NFPA group, P<0.01). CONCLUSION In untreated GHD, co-morbidities, including impairment of QoL, were more prevalent in controlled CD. Overall, both the groups responded similarly to GH replacement, suggesting that patients with GHD due to CD benefit from GH to the same extent as those with GHD due to NFPA.

Abstract
Serum insulin-like growth factor-1 (IGF-1) is a sensitive marker of growth hormone (GH) activity. The levels of IGF-1 vary widely, peaking during puberty and declining with advancing age. During adolescence, serum IGF-1 levels tend to correlate better with pubertal stage rather than chronological age. Here we discuss two cases of delayed puberty, both in their 20s, who presented with high serum IGF-1 but no clinical or biochemical evidence of hypersomatotropism as confirmed by appropriate GH response to an oral glucose challenge. Both individuals achieved full pubertal status with testosterone replacement therapy and their serum IGF-1 levels settled into normal age-specific range. We suggest that in chronologically adult individuals with delayed puberty, serum IGF-1 should not be interpreted on the basis of age-specific normal values but rather on their pubertal status. Furthermore, in the absence of another cause of elevated IGF-1, the expectation is that IGF-1 levels will decline towards age-normative ranges following androgen replacement therapy.

Abstract
BACKGROUND Although, it is accepted that there is an excess of cardiovascular mortality in acromegaly, it is uncertain whether this is due to the direct effects of growth hormone-induced-cardiomyopathy or is a consequence of atherosclerosis secondary to the metabolic syndrome often observed in this condition. Direct comparison of a mouse model of acromegaly to a mouse model of Laron's syndrome allowed us to carry out detailed phenotyping and better understand the role GH plays in the circulatory system. METHODS AND RESULTS Transgenic mice that overexpress the growth hormone gene (GH) developed gigantism, including insulin resistance and higher blood pressures commensurate with increased body mass. In these giant mice, the hearts were hypertrophied but haemodynamic studies suggested contractile function was normal. Segments of small arteries mounted in a pressure myograph showed vascular wall hypertrophy but a preserved lumen diameter. Vascular contractile function was normal. Mice in which the GH receptor gene was disrupted or 'knocked out' were dwarf and had low blood pressure, small hearts and blood vessels but a normally functioning circulation. Correlations of body mass with cardiovascular parameters suggested that blood pressure and structural characteristics develop in line with body size. CONCLUSION In this transgenic mouse model of acromegaly, there is cardiac and vascular hypertrophy commensurate with GH excess but normal function. Our findings support the contention that the excess mortality in this condition may be due to the development of hypertrophic cardiomyopathy rather than increased rates of atherosclerotic coronary artery disease.

Abstract
The treatment of choice for Cushing's syndrome remains surgical. The role for medical therapy is twofold. Firstly it is used to control hypercortisolaemia prior to surgery to optimize patient's preoperative state and secondly, it is used where surgery has failed and radiotherapy has not taken effect. The main drugs used inhibit steroidogenesis and include metyrapone, ketoconazole, and mitotane. Drugs targeting the hypothalamic-pituitary axis have been investigated but their roles in clinical practice remain limited although PPAR-gamma agonist and somatostatin analogue som-230 (pasireotide) need further investigation. The only drug acting at the periphery targeting the glucocorticoid receptor remains Mifepristone (RU486). The management of Cushing syndrome may well involve combination therapy acting at different pathways of hypercortisolaemia but monitoring of therapy will remain a challenge.

Abstract
Acromegaly is a rare disorder which affects about 50 of every million people. The disease typically causes swelling of the hands, feet, and face, and eventually permanent changes to areas such as the jaw, brow ridge, and cheek bones. The disease is often missed by physicians and progresses beyond where it might if it were identified and treated earlier. We consider a semi-automated approach to detecting acromegaly, using a novel combination of support vector machines (SVMs) and a morphable model. Our training set consists of 24 frontal photographs of acromegalic patients and 25 of disease-free subjects. We modelled each subject's face in an analysis-by-synthesis loop using the three-dimensional morphable face model of Blanz and Vetter. The model parameters capture many features of the 3D shape of the subject's head from just a single photograph, and are used directly for classification. We report encouraging results of a classifier built from the training set of real human subjects.

Abstract
Pegvisomant is a pegylated analogue of growth hormone (GH) that functions as a growth hormone receptor antagonist. Clinical trials of its use in acromegaly commenced in 1997; the drug was approved in the US in March 2003 and in Europe in November 2003. In the same year, it was made available on prescription in several European countries, with further launches due in 2004. Pegvisomant is capable of normalising serum insulin-like growth factor-I concentrations (the chief mediator of disease activity in acromegaly) in 97% of patients with active acromegaly, and therapy is associated with a significant improvement in the symptoms and signs of GH excess. Disease control is achievable with pegvisomant in patients who are wholly or partially resistant or do not tolerate somatostatin analogues; preliminary data suggest that the drug may be particularly suitable for patients with acromegaly and co-existent diabetes mellitus.

Abstract
Studies in animals and humans indicate that GH and IGF-I modulate immune function. Recently, it was reported that GH therapy increased the mortality in critically ill patients. The excessive mortality was almost entirely attributable to septic shock or multiorgan failure, suggesting that a GH-induced modulation of immune function was involved. In the present study, we examined whether GH or IGF-I influences the serum concentrations of mannan-binding lectin (MBL). MBL is a plasma protein of the innate immune system that initiates the complement cascade and activates inflammation after binding to carbohydrate structures on microbial surfaces. We performed a cross-over study of 16 healthy men examined during a control period, and during treatment with either GH or IGF-I for 6 d. The levels of MBL were more than doubled during GH treatment, whereas no changes were observed in the IGF-I group or during the control period (P < 0.001). IGF-I levels were elevated similarly during treatment with GH and IGF-I. Subsequently, we studied 30 healthy persons and 25 GH-deficient (GHD) patients randomized to treatment with GH or placebo in a double-blinded manner, and further included samples from 23 patients with active acromegaly examined before and after treatment with octreotide or the GH-receptor antagonist pegvisomant for 3 months. Baseline concentrations of MBL were lower in GHD patients and higher in acromegalic patients than in healthy subjects (P < 0.02). Treatment with GH doubled the MBL concentrations in healthy subjects and almost quadrupled the concentrations in GHD patients; whereas in acromegalic patients, the levels of MBL were reduced to approximately two thirds of the initial values during treatment with octreotide or pegvisomant. Our results demonstrate that treatment with GH, but not IGF-I, significantly increases MBL concentrations. The clinical consequences of this new link between the endocrine and the immune system remain to be elucidated.

Abstract
OBJECTIVE The diagnosis of Cushing's syndrome remains a major challenge in clinical endocrinology. Various screening tests are commonly used to support a biochemical diagnosis in the context of clinical suspicion. The aim of this study was to compare the sensitivity in the diagnosis of Cushing's syndrome of a single in-patient sleeping midnight cortisol to a standard 48-hour in-patient low-dose dexamethasone suppression test (LDDST) during the same admission. DESIGN A retrospective analysis was performed on 150 patients investigated in our department between the years 1970 and 1994 with a confirmed diagnosis of Cushing's syndrome. PATIENTS One hundred and fifty patients with a diagnosis of Cushing's syndrome were analysed: 110 with Cushing's disease; 12 with tumours with ectopic ACTH secretion; 8 with ACTH dependent Cushing's syndrome of so far undetermined origin; 17 with cortisol secreting adrenal tumours; 3 with adrenocortical nodular hyperplasia. Twenty normal volunteers and nine patients with non-endocrine conditions were also investigated as controls. MEASUREMENTS Plasma cortisol was measured by radioimmunoassay (RIA) in the 122 patients presenting after 1980, and by fluorimetry prior to this date. RESULTS In all the control subjects the sleeping midnight cortisol was < 50 nmol/l, below the lowest standard of the routine in-house RIA. In every patient with Cushing's syndrome the sleeping midnight cortisol was detectable with a value greater than 50 nmol/l, with a range of 70-2000 nmol/l. In contrast, in three cases, all of whom had proven Cushing's disease on histology, there was uncharacteristic complete suppression of plasma cortisol to < 50 nmol/l following the LDDST. CONCLUSION In this series of 150 cases, a single in-patient sleeping midnight cortisol above 50 nmol/l had a 100% sensitivity for the diagnosis of Cushing's syndrome, clearly different from normal subjects. In contrast, the low-dose dexamethasone suppression test had a sensitivity of 98% even when the drug was administered as an in-patient. We recommend that a low-dose dexamethasone suppression test should not be used alone for confirmation of Cushing's syndrome since it may miss 2% of cases.

Abstract
The enzyme nitric oxide (NO) synthase is present in the paraventricular nucleus, while nitric oxide has recently been shown to inhibit the stimulated release of corticotrophin-releasing hormone (CRH) in vitro. Thus the possible role of NO in regulating, vasopressin (AVP), which also plays an important role in pituitary-adrenal activity, has been investigated. The effects were studied of the NO donors, L-arginine, syndnonimine-1 (SIN-1) and sodium nitroprusside, on both the basal and stimulated release of AVP, employing a previously validated system. Rat hypothalami were incubated in either medium alone or medium containing the test substances and hormone release was measured by RIA. The effect of L-arginine in the presence of the NO synthase inhibitor, L-NMMA, was also investigated. L-arginine reduced KCl-evoked AVP release; this effect was reversed by L-NMMA and reduced by the addition of ferrous human Hb. Similarly, SIN-1 and sodium nitroprusside attenuated KCl-evoked AVP release. L-arginine also reduced IL-1 beta-stimulated AVP release. NO appears to directly and specifically inhibit the stimulated release of AVP from rat hypothalamic explants in vitro, similar to its effects on CRH. These findings provide further evidence that NO may be involved in neuroendocrine regulation.

Abstract
There is now considerable evidence that nitric oxide (NO) is an important neuroregulatory agent, but there has been very little investigation of the possible role of NO in neuroendocrine mechanisms. We have previously shown that acute rat hypothalamic explants can be used to study the regulation of hypothalamic neuropeptide release, and we have now utilised this experimental approach to investigate the putative involvement of NO in the control of the principal corticotropin-releasing hormone, CRH. We studied the direct effects of the NO precursor L-arginine (L-ARG), as well as the NO donors molsidomine and sodium nitroprusside, on both the basal and stimulated release of CRH; the stimuli used were non-specific depolarisation with potassium chloride (KCl) and the specific cytokine, interleukin-1 beta (IL-1 beta; 100 U/ml). L-ARG was tested in each experimental condition with and without contemporaneous addition of its competitive antagonist NG-monomethyl-L-arginine (L-NMMA). IL-1 beta-induced CRH release was also investigated in the presence of D-arginine (D-ARG), which is not active as a precursor to NO, and ferrous hemoglobin (Hb), a substance which is a potent inactivator of NO. None of the NO precursors (L-ARG, molsidomine, sodium nitroprusside) or antagonists (L-NMMA or Hb) was able to affect basal CRH release. However, L-ARG 10 and 100 microM were found to significantly inhibit the release of CRH induced by 40 mM KCl; CRH fell to 45% of its stimulated level at the higher dose of L-ARG. This effect was attenuated in the presence of L-NMMA at a ten-fold higher dose.(ABSTRACT TRUNCATED AT 250 WORDS)
