Abstract
OBJECTIVE Acromegaly is characterized by an excess of growth hormone (GH) and insulin like growth-factor 1 (IGF1), and it is strongly associated with cardiovascular diseases (CVD). Both acute and long-lasting pro-inflammatory effects have been attributed to IGF1. Previous results suggest the presence of systemic inflammation in treated patients. Here we assessed the association between treatment of acromegaly, systemic inflammation and vascular function. DESIGN Ex vivo cytokine production and circulating inflammatory markers were assessed in peripheral blood from treated and untreated acromegaly patients (N = 120), and compared them with healthy controls. A more comprehensive prospective inflammatory and vascular assessment was conducted in a subgroup of six treatment-naive patients with follow-up during treatment. RESULTS Circulating concentrations of VCAM1, E-selectin and MMP2 were higher in patients with uncontrolled disease, whereas the concentrations of IL18 were lower. In stimulated whole blood, cytokine production was skewed towards a more pro-inflammatory profile in patients, especially those with untreated disease. Prospective vascular measurements in untreated patients showed improvement of endothelial function during treatment. CONCLUSIONS Acromegaly patients are characterized by a pro-inflammatory phenotype, most pronounced in those with uncontrolled disease. Treatment only partially reverses this pro-inflammatory bias. These findings suggest that systemic inflammation could contribute to the increased risk of CVD in acromegaly patients.

Abstract
BACKGROUND Acromegaly is highly associated with thyroid disorders. However, the clinical characteristics of thyroid nodules in individuals with acromegaly who present with thyroid diseases have not been completely elucidated. METHODS Overall, 134 consecutive participants with growth hormone (GH)-secreting adenoma (n = 67) and non-functioning (NF) pituitary adenoma (n = 67) were recruited from the outpatient and inpatient patient department of The First Affiliated Hospital, Jinan University from August 2015 to August 2017. Thyroid ultrasonography was performed using an ultrasound system. The cytopathological results of fine-needle aspiration biopsy were analyzed by a pathologist according to the Bethesda system. Twenty-one patients with GH-secreting adenoma and thyroid disease underwent transsphenoidal pituitary adenoma resection and were followed up for 1 year. RESULTS The prevalence of thyroid disease increased in the GH-secreting adenoma group compared with that in the NF pituitary adenoma group. The number of hypoechoic, isoechogenic, heterogeneous, and vascular thyroid nodules increased in patients with GH-secreting adenoma plus thyroid disease compared with that in patients with NF pituitary adenoma plus thyroid disease. Finally, we found significant decreases in the morphology of solid nodules and significant increases in the morphology of cystic nodules after surgery compared with those before surgery in the cured group. Moreover, the numbers of heterogeneous and vascular thyroid nodules decreased significantly after surgery compared with those before surgery in the cured group. However, the characteristics of the thyroid nodules did not change after surgery compared with those before surgery in the non-cured group. CONCLUSIONS The numbers of hypoechoic, isoechoic, heterogeneous, and vascular thyroid nodules increased in patients with GH-secreting adenomas. In these patients, surgery resulted in significant changes from solid to cystic nodules and also reduced the numbers of heterogeneous and vascular thyroid nodules.

Abstract
CONTEXT New therapeutic strategies have developed for the management of acromegaly over recent decades. Whether this has improved mortality has not been fully elucidated. OBJECTIVE The primary aim was to investigate mortality in a nationwide unselected cohort of patients with acromegaly. Secondary analyses included time trends in mortality and treatment patterns. DESIGN A total of 1089 patients with acromegaly were identified in Swedish National Health Registries between 1987 and 2013. To analyse time trends, the cohort was divided into three periods (1987-1995, 1996-2004 and 2005-2013) based on the year of diagnosis. MAIN OUTCOME MEASURES Using the Swedish population as reference, standardized mortality ratios (SMRs) were calculated with 95% confidence intervals (CIs). RESULTS Overall SMR was 2.79 (95% CI: 2.43-3.15) with 232 observed and 83 expected deaths. Mortality was mainly related to circulatory diseases (SMR: 2.95, 95% CI: 2.35-3.55), including ischemic heart disease (2.00, 1.35-2.66) and cerebrovascular disease (3.99, 2.42-5.55) and malignancy (1.76, 1.27-2.26). Mortality decreased over time, with an SMR of 3.45 (2.87-4.02) and 1.86 (1.04-2.67) during the first and last time period, respectively (P = .015). During the same time periods, the frequency of pituitary surgery increased from 58% to 72% (P < 0.001) and the prevalence of hypopituitarism decreased from 41% to 23% (P < 0.001). CONCLUSIONS Excess mortality was found in this nationwide cohort of patients with acromegaly, mainly related to circulatory and malignant diseases. Although still high, mortality significantly declined over time. This could be explained by the more frequent use of pituitary surgery, decreased prevalence of hypopituitarism and the availability of new medical treatment options.

Abstract
Although somatostatin analogues (SSAs) are recommended as the first-line medical therapy for acromegaly, dopamine agonists (DAs) are also a therapeutic option for treatment. We aimed to assess and compare the efficacies of DAs and SSAs in treating acromegaly in clinical practice. We included 89 patients with acromegaly who took DAs (bromocriptine [BCT], n = 63; cabergoline [CAB], n = 11) or SSAs (n = 15) as a primary medical therapy for more than 3 months in the Seoul National University Hospital. The CAB (45.5%) and SSA (33.3%) groups achieved random GH levels of <2.5 ng/mL and the normal IGF-1 levels were significantly higher than in the BCT group (11.1%) (p = 0.009). We further included all the patients with acromegaly (n = 132) who had taken CAB, BCT, and SSAs as first- or second-line medical therapy. The CAB group showed similar efficacy as the SSA group in terms of the GH and insulin-like growth factor-1 (IGF-1) levels (57.6% for random GH level <2.5 ng/mL, 42.4% for normal IGF-1 levels, 36.4% for both). Logistic regression analysis revealed that medications, age, GH level, or IGF-1 level before medication, hyperprolactinemia, and prior gamma-knife surgery or radiation therapy, did not affect the therapeutic response. High pretreatment GH levels predicted poor treatment outcomes (odds ratio [95% confidence interval] = 0.95 [0.90-0.99]). CAB was effective in treating acromegaly at a relatively lower cost in patients with low pretreatment GH levels.

Abstract
Oxidative status is attributed to endothelial dysfunction and might be one of the key mechanisms of endothelial dysfunction in acromegaly. In this study, we aimed to investigate the effect of acromegaly on superoxide dismutase (SOD) and total antioxidant capacity (TAC) levels, and the possible influence of human manganese superoxide dismutase (MnSOD) polymorphism on these levels. 51 acromegaly patients and 57 age and sex matched healthy subjects were recruited to the study in Bezmialem Vakif University Hospital between 2011 and 2014. The median SOD and TAC levels were 42.7 (33-60) pg/mL and 1,313.7 (155-1,902) μM in acromegaly; and 46.3 (38-95) pg/mL and 1,607.3 (195-1,981) μM in healthy subjects (p < 0.001, p < 0.001). SOD levels were decreased in controlled and uncontrolled patients compared to healthy subjects (p = 0.05 and p = 0.002, respectively). Controlled and uncontrolled acromegaly displayed significantly decreased levels of TAC compared to healthy subjects (p < 0.05 and p < 0.001, respectively). SOD levels were not associated with MnSOD polymorphisms in acromegaly. In conclusion, this study showed that acromegaly was associated with decreased levels of SOD and TAC, and controlling the disease activity could not adequately improve these levels.

Abstract
There is scarce data on the clinical utility of volume measurement for growth hormone (GH)-secreting pituitary adenomas. The current study objective was to assess the association between pituitary adenoma volumes and baseline endocrine evaluation, initial surgical success rate, and disease control among patients with acromegaly. A retrospective cohort study was conducted at a clinical research center including patients with acromegaly due to GH-secreting pituitary adenomas. Baseline hormonal evaluation and adenoma characteristics according to MRI were collected. Volumetric measurements of pituitary adenomas were performed using a semi-automated lesion segmentation and tumor-volume assessment tools. Rates of post-operative medical treatment, radiation therapy, and re-operation were gathered from the patients' medical records. Twenty seven patients (11 females) were included, median age 21.0 years (interquartile range 29 years, range 3-61 years). Patients harboring adenomas with a volume <2 000 mm3 had higher chance to achieve disease remission [94.1% (n=16) vs. 50.0% (n=4), p<0.05]. Adenoma volumes positively correlated with baseline plasma GH levels before and after oral glucose administration, and with plasma IGF-I and PRL levels. Adenoma volume had negative correlation with morning plasma cortisol levels. Finally, patients harboring larger adenomas required 2nd surgery and/or medical treatment more often compared with subjects with smaller adenomas. Accurate 3D volume measurement of GH-secreting pituitary adenomas may be used for the prediction of initial surgery success and for disease control rates among patients with a GH-secreting pituitary adenomas and performs better than standard size assessments.

Abstract
INTRODUCTION In sporadic acromegaly, downregulation of AIP protein of the adenomas associates with invasive tumor features and reduced responsiveness to somatostatin analogues. AIP is a regulator of Gai signaling, but it is not known how the biological function of the Gai pathway is controlled. AIM To study GNAS and AIP mutation status, AIP and Gai-2 protein expressions, Ki-67 proliferation indices and clinical parameters in patients having primary surgery because of acromegaly at a single center between years 2000 and 2010. RESULTS Sixty patients (F/M, 31/29), mean age 49 (median 50), mean follow-up 7.7 years (range 0.6-14.0) underwent primary surgery. Four adenoma specimens (6.8%) harbored an AIP and 21 (35.6%) an activating GNAS (Gsp+) mutation. Altogether 13/56 (23%) adenomas had low AIP protein levels, and 14/56 (25%) low Gai-2 staining. In regression modeling, AIP expression associated with Gai-2 (P = 2.33 × 10-9) and lower Ki-67 (P = 0.04). In pairwise comparison, low AIP protein predicted high GH at last follow-up (mean 7.7 years after surgery, q = 0.045). Extent of treatments given for acromegaly associated with higher preoperative GH (P = 7.94 × 10-4), KNOSP (P = 0.003) and preoperative hypopituitarism (P = 0.03) and remission at last follow-up with change in 3-month postoperative IGF1 (P = 2.07 × 10-7). CONCLUSIONS We demonstrate, for the first time, that AIP protein expression associates with Gai-2 protein intensities in sporadic somatotropinomas, suggesting a joint regulation on somatostatin signaling. Low AIP level associates with higher proliferative activity and predicts high GH concentrations after long-term follow-up. The AIP mutation rate of 6.8% is fairly high, reflecting the genetic composition of the Finnish population.

Abstract
CONTEXT Acromegaly is a systemic disorder caused by a GH-secreting pituitary adenoma. As with other rare diseases, acromegaly registries developed in various European countries have provided us with important information. OBJECTIVE The objective of the study was to analyze the epidemiological, clinical, biochemical, and therapeutic data from the Mexican Acromegaly Registry (MAR). SETTING The setting of the study was a nationwide patient registry. DESIGN AND METHODOLOGY The MAR was created in 2009. It gathers data from 24 participating centers belonging to three different institutions using a specifically designed on-line platform. Only patients diagnosed after 1990 were included in the program. RESULTS A total of 2057 patients (51% female, mean age at diagnosis 41.1 ± 24.5 y) have been registered for an estimated prevalence of 18 cases per 1 million inhabitants. Hypertension, glucose intolerance, diabetes, and dyslipidemia were present in 27%, 18.4%, 30%, and 24% of the patients, respectively. The IGF-1 level at diagnosis and the concomitant presence of hypertension were significantly associated with the development of diabetes. Transsphenoidal surgery was the primary treatment in 72% of the patients. Pharmacological treatment, mostly with somatostatin analogs, was administered primarily and adjunctively in 26% and 54% of the patients, respectively. Treatment choice varied among the three participating institutions, with the predominance of pharmacological therapy in two of them and of radiation therapy in the third. Therapeutic outcomes were similar to those reported in the European registries. CONCLUSIONS The MAR is the largest and first non-European registry of the disease. Our findings highlight important within-country differences in treatment choice due to variations in the availability of resources.

Abstract
OBJECTIVE Even if treated, acromegaly has a considerable impact on patient quality of life (QoL); despite this, the exact clinical determinants of QoL in acromegaly are unknown. This study retrospectively examines a cohort of treated patients with acromegaly, with the aim of identifying these determinants. METHODS Retrospective survey analysis, with 165 patients included in the study. All patients completed a survey, which included demographic data and the clinical details of their disease, the Short Form-36 Health Survey (SF-36), the revised Beck Depression Inventory (BDI-II), and the Bern Embitterment Inventory (BEI). Stepwise regression was used to identify predictors of QoL. RESULTS The strongest predictors of the physical component score of the SF-36 were (in order of declining strength of association): Delay between first presentation of the disease and diagnosis, body mass index (BMI), number of doctors visited before the diagnosis of acromegaly, and age at diagnosis. For the mental component score, the strongest predictors were: number of doctors visited, previous radiotherapy, and age at study entry; and, for the BDI-II score: number of doctors visited, previous radiotherapy, age at study entry, and employment status at the time of diagnosis. The following were predictors of the BEI score: number of doctors visited, and age at study entry. CONCLUSION Diagnostic delay and lack of diagnostic acumen in medical care provision are strong predictors of poor QoL in patients with acromegaly. Other identified parameters are radiotherapy, age, BMI, and employment status. An efficient acromegaly service should address these aspects when devising disease management plans. ABBREVIATIONS BDI-II = Beck Depression Inventory II BEI = Bern Embitterment Inventory BMI = body mass index IGF-1 = insulin-like growth factor 1 MCS = mental component summary (score) PCS = physical component summary (score) QoL = quality of life SDS = standard deviation score SF-36 = Short Form-36 Health Survey.

Abstract
OBJECTIVE The aim of this study was to evaluate the proportion of patients with acromegaly who remained on long-term lanreotide depot after completion of an open-label multicenter phase III clinical trial (SALSA: A Multi Center Open Label Study to Assess the Ability of Subjects With Acromegaly or Their Partners to Administer Somatuline Autogel), compare baseline and long-term follow-up symptoms scores, and correlate scores with individual longitudinal clinical outcomes. METHODS Records of all subjects previously enrolled at the Massachusetts General Hospital site of SALSA were reviewed. Those who remained on lanreotide were interviewed and asked to complete a questionnaire that they had filled out in SALSA in 2007 regarding their current symptomatology and injection side effects, as well as to complete the Acromegaly Quality of Life Questionnaire. Furthermore, clinical, biochemical, and radiographic data related to acromegaly and its comorbidities were tracked throughout follow-up. RESULTS Six out of 7 patients chose to remain on lanreotide, and 5 of them continued lanreotide depot through last follow-up, for up to 8 years or in 1 case until death. In all cases, lanreotide remained well tolerated, and insulin-like growth factor-1 levels and pituitary imaging remained well controlled on stable doses. While comorbidities persisted or developed, the self-reported symptom score after up to 8 years of therapy showed a significant decrease in frequency or resolution in symptoms that were reported at baseline. CONCLUSION This study shows a significant decrease in frequency or resolution in self-reported symptoms in well-controlled patients receiving long-term lanreotide therapy.

Abstract
BACKGROUND Cardiovascular complications, including arrhythmias and cardiac sudden death, are the most common causes of enhanced mortality in acromegaly. However, few data are available on cardiac autonomic functions and sympathovagal balance in acromegalic patients. OBJECTIVE The aim of this study was to investigate both the time and frequency domain parameters of Heart Rate Variability (HRV), in order to characterize the cardiac autonomic functions in patients affected by acromegaly. This study correlated anthropometric, metabolic, echocardiographic parameters and blood pressure with those relating to HRV, to identify the main factors responsible for the HRV related alterations possibly present. We also aimed to analyze the effects of the treatment with somatostatin analogues (SSAs) on HRV. MATERIALS AND METHODS This study enrolled 47 acromegalic patients (23 males, age 49.1 ± 13.5 years) and 37 (13 males) age matched (52.3 ± 13.3 years) healthy subjects. All participants underwent 12-lead 24 h ECG Holter recordings and a HRV analysis of the ECG tracings was performed. The parameters obtained from the time domain analysis of HRV included pNN50, SDNN, SDNN index, SDANN and RMSSD. The power spectral analysis of HRV was obtained by summing powers of the LF (low frequency) and the HF (high frequency) band. Sympathovagal balance was estimated by calculating the LF/HF ratio during 24 h and 15 min of clinostatism. The HRV of 28 acromegalic patients was studied before and after SSAs treatment. RESULTS Acromegalic patients showed significantly lower SDNN and SDANN compared to controls. Diabetic and non-diabetic acromegalic patients showed decreased SDNN and SDANN, when compared to healthy subjects. Diabetic acromegalic patients had a lower LF/HF ratio during 24 h when compared to non-diabetic acromegalic patients. Similar results were obtained analyzing patients affected by acromegaly and impaired glucose tolerance. SDNN and SDANN were lowered by hypertension in the acromegalic population, when compared to controls, and hypertensive acromegalic patients also displayed a decreased LF/HF ratio during 24 h when compared to normotensive acromegalic subjects. Patients with ventricular arrhythmias in Lown classes 3-5 showed a decreased SDANN compared to patients in Lown class 0-2. The treatment with SSAs was able to ameliorate all the time domain parameters of HRV, without altering the 24 h LF/HF ratio. CONCLUSION Cardiac autonomic functions and sympathovagal balance are altered in patients affected by acromegaly and could be ameliorated by SSAs therapy. HRV analysis allows an estimation of the autonomic sympathovagal balance and may be a useful clinical tool for the cardiac risk stratification in acromegalic patients.

Abstract
The prevalence of acromegaly is estimated to be 8-24/100,000, but several recent studies suggest it is underestimated. In particular, acromegaly is considered more prevalent in patients with type 2 diabetes mellitus (T2DM) than in the normal population. This study aimed to evaluate the prevalence of acromegaly in hospitalized patients with T2DM. A total of 327 hospitalized patients with T2DM were recruited as subjects. If serum insulin-like growth factor 1 (IGF-1) levels were found to be elevated, random GH level was measured or oral glucose tolerance test (OGTT) was performed. Five patients with elevated serum IGF-1 levels and random GH level or inadequate suppression of GH in the OGTT underwent pituitary magnetic resonance imaging. Of those patients, pituitary adenoma was detected in 2 patients. These 2 patients were diagnosed with acromegaly, as they also exhibited mild acromegalic features. Intriguingly, both these patients exhibited severe macroangiopathy and an absence of microangiopathy. The prevalence of acromegaly in the hospitalized patients with T2DM in this study was therefore 0.6%, suggesting a higher prevalence than that predicted. Although a large-scale prospective study is required to clarify the precise prevalence of acromegaly in hospitalized patients with T2DM, the present study shows that it is useful to screen hospitalized patients with T2DM for acromegaly by measuring their serum IGF-1 level.

Abstract
OBJECTIVE The complex management of acromegaly has transformed this disease into a chronic condition, with the risk of patients being lost to follow-up. The objective of this study was to estimate the proportion of acromegalic patients lost to follow-up in France and to determine the impact that abandoning follow-up has on the disease and its management. DESIGN ACROSPECT was a French national, multicentre, cross-sectional, observational study. METHODS Acromegalic patients were considered lost to follow-up if no new information had been entered in their hospital records during the previous 2 years. They were traced where possible, and data were collected by means of a recall visit or questionnaire. RESULTS In the study population, 21% of the 2392 acromegalic patients initially followed in 25 tertiary endocrinology centres were lost to follow-up. At their last follow-up visit, 30% were uncontrolled, 33% were receiving medical therapy and 53% had residual tumour. Of the 362 traced, 62 had died and 77% were receiving follow-up elsewhere; the leading reason for abandoning follow-up was that they had not been informed that it was necessary. Our analysis of the questionnaires suggests that they were not receiving optimal follow-up. CONCLUSIONS This study underlines the need to better inform acromegalic patients of the need for long-term follow-up, the absence of which could be detrimental to patients' health, and to develop shared care for what must now be regarded as a chronic disease.

Abstract
Acromegaly is predominantly caused by a pituitary adenoma, which secretes an excess of GH resulting in increased IGF1 levels. Most of the GH assays used currently measure only the levels of the 22 kDa form of GH. In theory, the diagnostic sensitivity may be lower compared with the previous assays, which have used polyclonal antibodies. Many GH-secreting adenomas are plurihormonal and may co-secrete prolactin, TSH and α-subunit. Hyperprolactinaemia is found in 30-40% of patients with acromegaly, and hyperprolactinaemia may occasionally be diagnosed before acromegaly is apparent. Although trans-sphenoidal surgery of a GH-secreting adenoma remains the first treatment at most centres, the role of somatostatin analogues, octreotide long-acting repeatable and lanreotide Autogel as primary therapy is still the subject of some debate. Although the normalisation of GH and IGF1 levels is the main objective in all patients with acromegaly, GH and IGF1 levels may be discordant, especially during somatostatin analogue therapy. This discordance usually takes the form of high GH levels and an IGF1 level towards the upper limit of the normal range. Pasireotide, a new somatostatin analogue, may be more efficacious in some patients, but the drug has not yet been registered for acromegaly. Papers published on pasireotide have reported an increased risk of diabetes mellitus due to a reduction in insulin levels. Pegvisomant, the GH receptor antagonist, is indicated - alone or in combination with a somatostatin analogue - in most patients who fail to enter remission on a somatostatin analogue. Dopamine-D2-agonists may be effective as monotherapy in a few patients, but it may prove necessary to apply combination therapy involving a somatostatin analogue and/or pegvisomant.

Abstract
BACKGROUND In active acromegaly, pathologically elevated GH and IGF-1 levels are associated with increased bone turnover and a high bone mass, the latter being sustained after normalization of GH values. In a cross-sectional study design, we have previously reported a high prevalence of vertebral fractures (VFs) of about 60% in patients with controlled acromegaly, despite normal mean bone mineral density (BMD) values. Whether these fractures occur during the active acromegaly phase or after remission is achieved is not known. OBJECTIVE Our objective was to study the natural progression of VFs and contributing risk factors in patients with controlled acromegaly over a 2.5-year follow-up period. METHODS Forty-nine patients (mean age 61.3 ± 11.1 years, 37% female) with controlled acromegaly for ≥ 2 years after surgery, irradiation, and/or medical therapy and not using bisphosphonates were included in the study. Conventional spine radiographs including vertebrae Th4-L4 were assessed for VFs according to the Genant method. VF progression was defined as development of new/incident fractures and/or a minimum 1-point increase in the Genant scoring of preexisting VFs. BMD was assessed by dual-energy x-ray absorptiometry (Hologic 4500). RESULTS Prevalence of baseline VFs was 63%, being highest in men, and fractures were unrelated to baseline BMD. VF progression was documented in 20% of patients, especially in men and in case of ≥ 2 VFs at baseline. VF progression was not related to BMD values or BMD changes over time. CONCLUSION Findings from this longitudinal study show that VFs progress in the long term in 20% of patients with biochemically controlled acromegaly in the absence of osteoporosis or osteopenia. These data suggest that an abnormal bone quality persists in these patients after remission, possibly related to pretreatment long-term exposure to high circulating levels of GH.

Abstract
Somatotroph adenomas secrete supraphysiological amounts of GH, causing acromegaly. We have previously hypothesized that epithelial mesenchymal transition (EMT) may play a central role in the progression of these adenomas and that epithelial splicing regulator 1 (ESRP1) may function prominently as a master regulator of the EMT process in pituitary adenomas causing acromegaly. To further elucidate the role of ESRP1 in somatotroph adenomas and in EMT progression, we used RNA sequencing (RNAseq) to sequence somatotroph adenomas characterized by high and low ESRP1 levels. Transcripts identified by RNAseq were analyzed in 65 somatotroph adenomas and in GH-producing pituitary rat cells with a specific knockdown of Esrp1. The clinical importance of the transcripts was further investigated by correlating mRNA expression levels with clinical indices of disease activity and treatment response. Many of the transcripts and isoforms identified by RNAseq and verified by quantitative PCR were involved in vesicle transport and calcium signaling and were associated with clinical outcomes. Silencing Esrp1 in GH3 cells resulted in changes of gene expression overlapping the data observed in human somatotroph adenomas and revealed a decreased granulation pattern and attenuated GH release. We observed an alternative splicing pattern for F-box and leucine-rich repeat protein 20, depending on the ESPR1 levels and on changes in circulating IGF-I levels after somatostatin analog treatment. Our study indicates that ESRP1 in somatotroph adenomas regulates transcripts that may be essential in the EMT progression and in the response to somatostatin analog treatment.

Abstract
Acromegaly is a chronic disease with increased morbidity and mortality, where usually multiple treatment modalities are used. The somatostatin analogs (SSAs) are the mainstay of medical therapy but, in many patients, including those with a germline mutation in the aryl hydrocarbon receptor-interacting protein (AIP) gene, disease activity cannot be controlled with these drugs. Previous data have suggested the involvement of the tumor-suppressor gene ZAC1 in the mechanism of action of SSAs, and more recent findings suggested that SSAs could regulate AIP, which in turn can stimulate ZAC1, therefore suggesting the existence of a SSA-AIP-ZAC1-somatostatin effect pathway. The current review discusses these novel observations, highlighting their significance in the treatment of sporadic and familial somatotroph adenomas.

Abstract
Although somatostatin analogues are effective medical therapy for acromegaly, the serum insulin-like growth factor-I (IGF-I) levels remain uncontrolled in 35% of patients. Combined therapy with octreotide LAR and cabergoline has been reported to normalize IGF-I levels in 42-56% of Caucasian patients with acromegaly. However, it remains to be clarified whether combination therapy is effective in Japanese patients and on tumor shrinkage. We conducted a retrospective study on combined therapy in patients with octreotide-resistant acromegaly. Ten patients with acromegaly who showed octreotide-resistance were enrolled in this study. Cabergoline was added in doses of 0.25-2.0mg/week. Serum GH and IGF-I levels and tumor volume were assessed before and after treatment, and factors correlated with effect of the combined therapy were analyzed. Although serum GH levels did not decrease, serum IGF-I levels significantly decreased by 20% after 6 months of combined therapy compared with baseline (p < 0.05). As a result, serum IGF-I levels normalized in 30% of the patients. Tumor volume after combined therapy also significantly decreased (p < 0.01). There were no correlations between the decrease of serum IGF-I levels during combined therapy and the response of GH in a bromocriptine test, random GH, IGF-I, and PRL levels, the tumor volume, and the expression of PRL and dopamine D2 receptor in the tumor. In conclusion, we demonstrated that the addition of cabergoline to octreotide LAR is a beneficial option in Japanese patients with octreotide-resistant acromegaly, irrespective of serum PRL levels and the response of GH levels in a bromocriptine test.

Abstract
Hyperglycemia is seldom described in young patients with pituitary gigantism. Here, we describe the case of a 17-year-old Taiwanese boy who developed depressive mood disorder and diabetic ketoacidosis (DKA) at the presentation of pituitary gigantism. The boy complained of lethargy and dysphoric mood in June 2008. He presented at the emergency department with epigastralgia and dyspnea in January 2009. Results of laboratory tests suggested type 1 diabetes mellitus with DKA. However, serum C-peptide level was normal on follow-up. Although he had no obvious features of acral enlargement, a high level of insulin-like growth factor 1 was detected, and a 75 g oral glucose suppression test showed no suppression of serum growth hormone levels. A pituitary macroadenoma was found on subsequent magnetic resonance imaging. The pituitary adenoma was surgically removed, followed by gamma-knife radiosurgery, and Sandostatin long-acting release treatment. He was then administered metformin, 500 mg twice daily, and to date, his serum glycohemoglobin has been <7%.

Abstract
The somatostatin analog lanreotide Autogel has proven to be efficacious for treating acromegaly in international studies and in clinical practices around the world. However, its efficacy in Japanese patients has not been extensively evaluated. We examined the dose-response relationship and long-term efficacy and safety in Japanese patients with acromegaly or pituitary gigantism. In an open-label, parallel-group, dose-response study, 32 patients (29 with acromegaly, 3 with pituitary gigantism) received 5 injections of 60, 90, or 120 mg of lanreotide Autogel over 24 weeks. Four weeks after the first injection, 41% of patients achieved serum GH level of <2.5 ng/mL and insulin-like growth factor-I (IGF-I) level was normalized in 31%. Values at Week 24 were 53% for GH and 44% for IGF-I. Dose-dependent decreases in serum GH and IGF-I levels were observed with dose-related changes in pharmacokinetic parameters. In an open-label, long-term study, 32 patients (30 with acromegaly, 2 with pituitary gigantism) received lanreotide Autogel once every 4 weeks for a total of 13 injections. Dosing was initiated with 90 mg and adjusted according to clinical responses at Weeks 16 and/or 32. At Week 52, 47% of patients had serum GH levels of <2.5 ng/mL and 53% had normalized IGF-I level. In both studies, acromegaly symptoms improved and treatment was generally well tolerated although gastrointestinal symptoms and injection site induration were reported. In conclusion, lanreotide Autogel provided early and sustained control of elevated GH and IGF-I levels, improved acromegaly symptoms, and was well tolerated in Japanese patients with acromegaly or pituitary gigantism.

Abstract
OBJECTIVE Patients with prolactinoma seem to be at high risk for osteopenia. However, whether patients with various pathological sellar tumors have risk for osteopenia remains unclear. The aim of the present study is to assess the bone mass alteration in patients with various sellar tumors and further to investigate the risk factors of bone mass alteration. MATERIALS AND METHODS 65 premenopausal female patients with diverse sellar tumors and 325 normal controls were enrolled in this study. Bone mineral density (BMD) of lumbar spine and comprehensive endocrinological evaluations were undergone. RESULTS Compared to the matched controls, BMD of patients with prolactinoma or craniopharyngioma significantly decreased. Patients with sellar meningioma and nonfunctioning adenoma are with a decreasing tendency and patients with growth hormone-secreting adenoma are with an increasing tendency compared to controls. Univariate and multivariate regression analysis indicated that the bone loss in prolactinomas was significantly correlated to disease duration and hypogonadism. CONCLUSION In the premenopausal women, patients with prolactinoma or craniopharyngioma are often accompanied with osteopenia or osteoporosis, and disease duration and hypogonadism are the risk factors of bone loss in prolactinoma. Continuous surveillance of BMD is recommended in patients with meningioma or nonfunctioning adenoma.

Abstract
The examination of 72 males with somatotropinoma has found that 65% of such patients have hypogonadism which is essential in pathogenesis of sexual dysfunction and spermatogenetic disorders. However, hypogonadism in males with somatotropinoma does not provoke sexual dysfunction in most the cases. High production of somatotropic hormone and insulin-like growth factor 1 in somatotropinoma leads to prostatic hyperplasia which is not accompanied with a rise of a PSA level and symptoms of infravesical obstruction.

Abstract
OBJECTIVE Ten percent of patients with prolactinoma fail to respond with normalization of prolactin (PRL) and tumor shrinkage under dopamine agonist (DA) therapy. The resistance to treatment is linked to a loss of dopamine receptor 2 (D2DR). Prolactinomas express somatostatin (SST) receptor subtypes, SSTR1, 2, and 5. The aim of this study was to determine whether different SST compounds could overcome the resistance to DA in prolactinomas. DESIGN AND METHODS The efficacy of SSTR1, SSTR2, and SSTR5 ligands; the universal SST ligand, SOM230; and the chimeric SST-DA compound, BIM-23A760, was compared with cabergoline in suppressing PRL secretion from primary cultures of ten prolactinomas (six DA responders and four DA resistant). Receptor mRNAs were assessed by quantitative PCR. RESULTS The mean mRNA levels for D2DR, SSTR1, SSTR2, and SSTR5 were 92.3+/-47.3, 2.2+/-1.4, 1.1+/-0.7, and 1.6+/-0.6 copy/copy beta-glucuronidase (beta-Gus) respectively. The SSTR1 agonist, BIM-23926, did not suppress PRL in prolactinomas. In a DA-resistant prolactinoma, it did not inhibit [(3)H]thymidine incorporation. The SSTR5 compound, BIM-23206, produced a dose-dependent inhibition of PRL release similar to that of cabergoline in three DA-sensitive prolactinomas. BIM-23A760 produced a maximal PRL inhibition superimposable to that obtained with cabergoline with a lower EC(50) (0.5+/-0.1 vs 2.5+/-1.5 pmol/l). In DA-resistant prolactinomas, BIM-23206 and SOM230 were ineffective. Cabergoline and BIM-23A760 produced a partial inhibition of PRL secretion (19+/-6 and 21+/-3% respectively). CONCLUSION Although the SSTRs are expressed in prolactinomas, the somatostatinergic ligands analyzed do not appear to be highly effective in suppressing PRL. D2DR remains the primary target for effective treatment of prolactinomas.

Abstract
BACKGROUND Acromegaly is an excessive GH secretion, which in most cases, is caused by a pituitary GH-secreting adenoma. Traditional treatment of acromegaly consists of surgery, drug therapy, and eventually radiotherapy. The aim of this retrospective study is to evaluate the results of transsphenoidal endoscopic surgery in a group of patients with intrasellar GH adenoma who were operated by a pituitary specialist surgeon. We shall then argue about the economical advantages, for the NHS of a developing country, between surgical and medical treatment. METHODS We have analyzed data from 33 patients with intrasellar GH tumor who had been referred to the neuroendocrine department of the HGF, Brazil. The patients underwent a transsphenoidal endoscopic adenomectomy for acromegaly between 2000 and 2005. Their ages were between 20 and 67 years (mean, 44 years) at the moment of surgery. No cavernous sinus invasion was present. Follow-up was a median of 2 years (range, 12 months-6 years). RESULTS All 33 patients had intrasellar adenoma, 84.84% of patients achieved remission by surgery. One patient was operated twice and reached hormonal normalization. Five patients still had the disease and refused a second surgery. A treatment with octreotide was started for these 5 patients and resulted in an adequate control of GH and IGF-1 levels. No patients had radiotherapy. CONCLUSION Our patients, with intrasellar GH tumor, operated by a pituitary specialist neurosurgeon had remission rates approaching those obtained by most specialized neurosurgical centers worldwide. For equal results, our study shows that the surgical treatment is the best issue for the patient and for the NHS.

Abstract
Pituitary tumors are the most common intracranial neoplasms. They are commonly encountered by the gynecologist during an evaluation for galactorrhea, menstrual disturbances, or infertility. Although the majority of these tumors are benign, their impact on the endocrine and nervous system can be striking. The availability of neuroimaging techniques has allowed for more rapid diagnosis, affording earlier treatment. This review is intended to describe the common pituitary tumors seen by the gynecologist, and their impact on reproduction and fertility in the female patient.

Abstract
OBJECTIVE To report a rare side effect of gamma knife treatment of pituitary macroadenoma. CASE REPORT In a forty-one-year old female patient acromegaly was diagnosed due to a growth hormone secreting pituitary macroadenoma. Following transsphenoidal surgery the patient underwent gamma knife treatment for persistent uncontrolled acromegaly activity of residual tumor, infiltrating the left cavernous sinus. 15 months later, complex partial seizures were diagnosed and 17 months after gamma knife treatment a gadolinium enhancing lesion was detected in her left medial temporal lobe. Radiation induced changes, radiation necrosis or a glioma were considered. Neuropsychological testing indicated potentially significant post-surgical deficits. Therefore, surgical action was postponed and anti-epileptic treatment was started. Four months later she was free of seizures and an MR scan showed an almost complete regression of the gadolinium enhancing lesion, indicating that it had been due to radiation induced changes. CONCLUSION Gamma knife surgery of a pituitary adenoma may cause radiation induced MR changes of the mesial temporal lobe mimicking glioma or radionecrosis and cause symptomatic epileptic seizures. The awareness of this rare complication is important to avoid unnecessary and potentially harmful diagnostic or therapeutic interventions.

Abstract
BACKGROUND Transsphenoidal adenomectomy has been the accepted surgical management for treatment of growth hormone (GH)-secreting pituitary adenomas. Although the goal of treatment might be to keep the GH level in the reference range, the actual definition of success in control of acromegaly is not yet clear. METHODS The aim of this study was to analyze prospectively the result of transsphenoidal adenoctomy performed over 23-year period by a single neurosurgeon in one center. The analysis has been performed to determine which preoperative factor could significantly influence the long term outcome. This series consisted of 151 patients. The preoperative hormonal studies documenting the high GH and/or insulin-like growth factor were available in all the cases. At least 1 laboratory report documenting the postoperative level of hormones was also available for all of them. Transsphenoidal microsurgical adenomectomy was performed in all the cases. RESULTS There were 90 patients with pure GH-secreting adenoma (59.6%) with the highest GH level of 235 mU/L. A second group of 12 patients had normal GH level but elevated serum level of insulin-like growth factor 1 (8%). The group with mixed secretion of GH and prolactin included 49 cases (32.4%). There was no postoperative mortality. Cerebrospinal fluid leakage occurred in 12 patients. Transient diabetes insipidus was encountered in 19 cases (12.6%) and long lasting diabetes insipidus in 2 patients (1.3%). Early and minor hypopituitarism was encountered in 14 patients, whereas a persistent condition occurred mainly after irradiation in 14 other cases. Normal postoperative serum GH level could be achieved in 98 patients (94.2%) of 104 cases with full follow-up. CONCLUSION In the developing countries, early diagnosis and proper surgical extirpation of the GH-secreting adenoma by an experienced and dedicated pituitary surgeon is mandatory to reduce the mortality and increase the chance of cure of this rather mortal endocrionopathy.

Abstract
OBJECTIVE AND IMPORTANCE "Silent" somatotrophinomas are very rare, typically large pituitary adenomas that present with mild or no acromegalic features despite positive immunostaining for growth hormone and autonomous (nonglucose-suppressible) growth hormone secretion. Because of this, they may be amenable to treatment with somatostatin analogues. CLINICAL PRESENTATION We report a giant somatotrophinoma (7 cm in maximal diameter) in a young woman with 6 years of amenorrhea who had no clinical features of acromegaly despite frankly elevated serum insulin-like growth factor 1 level at the time of diagnosis. Immunohistochemistry revealed focal strong positive staining for growth hormone in only 10% of the surgical specimen. Mutations in exons 8 or 9 of GNAS1, which are present in 40% of somatotrophinomas, were absent in the surgical specimen. The patient's clinical, biochemical, and radiological presentation is described and is compared with previously reported cases of silent somatotrophinomas. INTERVENTION Because of the size and visual symptomatology, partial resection was performed via a transcranial approach. External adjuvant beam radiotherapy was used. As insulin-like growth factor 1 levels remained elevated, treatment with somatostatin analogue is being pursued. CONCLUSION This case represents one of the largest somatotrophinomas described to date, and it demonstrates that serum insulin-like growth factor 1 should be measured even in the absence of acromegalic features in patients presenting with apparently nonsecreting macroadenomas. In addition to surgery and radiotherapy, somatostatin analogues may play an important role in controlling tumor growth.
