Abstract
Context Germline succinate dehydrogenase subunit B (SDHB) pathogenic variants are characteristic of familial paraganglioma (PGL) syndrome type 4. This syndrome frequently presents with abdominal PGL and has high tendency for locally aggressive behavior and distant metastasis. The vast majority of pituitary adenomas (PAs) are sporadic. However, PAs can be part of a number of familial tumor syndromes such as multiple endocrine neoplasia type 1 (MEN 1) or more rarely in association with pheochromocytoma and PGL (referred to as 3P syndrome). Only a limited number of PAs in association with SDHB-related PGL has been reported and the vast majority occurred subsequently or simultaneously with pheochromocytoma/PGL (collectively abbreviated as PPGL). In this report, we describe a young patient who had a giant pituitary macroprolactinoma resistant to large doses of cabergoline (CBG) and external beam radiotherapy (XRT). The patient did not have personal history of PPGL but was found to carry a germline SDHB pathogenic variant. Case report A 38-year-old woman presented with headache, visual disturbances and galactorrhea and was found to have a 34-mm macroprolactinoma. She was treated with CBG 3-4 mg per week but PA continued to grow and caused significant cranial pressure symptoms. She underwent two transsphenoidal surgeries with rapid tumor recurrence after each one. She received XRT but PA continued to grow. She was finally treated with temozolomide with excellent response. Whole exome and subsequent Sanger sequencing confirmed that she has a pathogenic monoallelic SDHB mutation (NM_003000:c.C343T, p.R115*). PA tissue showed loss of heterozygosity for the same mutation and absent SDHB immunostaining confirming the pathogenic role of this SDHB mutation. Conclusion Germline SDHB mutations can rarely cause PA in the absence of PPGL. They should be considered as a possible cause of aggressiveness and resistance to dopamine agonists in similar cases.

Abstract
Seizures are a common neurological disorder that affects people of all ages. These sudden, uncontrolled electrical disturbances in the brain can cause a variety of symptoms, including convulsions, loss of consciousness, and abnormal sensations. While seizures have long been recognized as a potential cause of hormonal imbalances, recent research has shed new light on the link between seizures and prolactin. The study involved 30 adult female Wistar rats, which were divided into a control group (treated with normal saline) and four treatment groups: chronic group (treated with 30 mg/kg pentylenetetrazol intraperitoneally three days a week for 10 weeks), chronic + Levetiracetam (50 mg/kg, gavage), chronic + Cabergoline (0.05 mg/kg, gavage), and chronic + Levetiracetam (25 mg/kg) + cabergoline (0.025). The drugs were administered three days a week for 10 weeks. Field action potentials were recorded from the CA1 area of the hippocampus using eLab after anesthetizing the animals with a ketamine-xylazine combination (70 +7 mg/kg). The prolactin levels were measured using the ELISA method after serum preparation. The findings indicate that the use of levetiracetam as an anticonvulsant drug resulted in a significant decrease in the amount of prolactin and spike number of convulsive activities compared to the chronic group. However, the amplitudes of convulsive activities did not show a significant difference between the control and other treatment groups. In conclusion, investigating the possibility of subclinical seizures and utilizing anticonvulsant medications in hyperprolactinemia that is resistant to treatment are crucial in treating infertility.

Abstract
ABSTRACT Repeated stress produces hyperalgesic priming in preclinical models, but underlying mechanisms remain uncertain. As stress engages kappa opioid receptors (KORs), we hypothesized that repeated administration of KOR agonists might mimic, in part, stress-induced hyperalgesic priming. The potential contribution of circulating prolactin (PRL) and dysregulation of the expression of PRL receptor (PRLR) isoforms in sensory neurons after KOR agonist administration was also investigated. Mice received 3 daily doses of U-69593 or nalfurafine as a "first-hit" stimulus followed by assessment of periorbital tactile allodynia. Sixteen days after the first KOR agonist administration, animals received a subthreshold dose of inhalational umbellulone, a TRPA1 agonist, as the second-hit stimulus and periorbital allodynia was assessed. Cabergoline, a dopamine D2 receptor agonist, was used to inhibit circulating PRL in additional cohorts. Prolactin receptor isoforms were quantified in the V1 region of the trigeminal ganglion after repeated doses of U-69593. In both sexes, KOR agonists increased circulating PRL and produced allodynia that resolved within 14 days. Hyperalgesic priming, revealed by umbellulone-induced allodynia in animals previously treated with the KOR agonists, also occurred in both sexes. However, repeated U-69593 downregulated the PRLR long isoform in trigeminal neurons only in female mice. Umbellulone-induced allodynia was prevented by cabergoline co-treatment during priming with KOR agonists in female, but not male, mice. Hyperalgesic priming therefore occurs in both sexes after either biased or nonbiased KOR agonists. However, a PRL/PRLR-dependence is observed only in female nociceptors possibly contributing to pain in stress-related pain disorders in females.

Abstract
OBJECTIVE The treatment strategy for nonfunctioning pituitary adenomas (NFPA) includes surgery, radiotherapy, medical treatment, or follow-up. Prior series of patients with NFPAs followed without intervention include small numbers of patients with macroadenomas. This study investigated the natural history of patients with macroadenomas followed without treatment. DESIGN AND PATIENTS Retrospective cohort study included patients>18 years, with a diagnosis of NFPA ≥ 10 mm who were naïve to surgery or medical treatment and followed more than 12 months after diagnosis. Patients with chiasmal threat were excluded. Follow-up terminated if the patient underwent surgery, received cabergoline or was lost to follow-up. MEASUREMENTS Data collected included evaluation of tumour characteristics and size by MRI, symptoms including visual disturbances, and hormonal levels. Tumour growth was defined as maximal diameter increase of ≥2 mm. RESULTS The cohort included 49 patients (30 males, mean age 68.0 ± 12.0 years). At diagnosis, the average tumour size was 17.8 ± 5.9 mm. Mean follow-up time was 4.9 ± 4.9 years. Increase in tumour size occurred in 16 patients (33%), with an average growth of 5.1 ± 4.4 mm. Reduction in tumour size occurred in 10 patients (20%), with a mean decrease of 3.5 ± 1.3 mm. Twenty-three patients remained with stable tumours. Overall, 33 patients (67%) were observed without any intervention; 3 patients were operated and 13 were treated with cabergoline. None of the parameters including age, gender, baseline tumour size, invasiveness, visual disturbances, or hypopituitarism at diagnosis, predicted tumour growth. CONCLUSION Observation of NFPAs without surgery or medical therapy is a reasonable approach in selected patients. In our study, no parameter predicted tumour growth.

Abstract
Simple, Economic, and selective spectrofluorimetric and stability-indicating thin layer chromatographic (TLC) with fluorescence detection methods were developed for the determination of Cabergoline, a potent prolactin inhibitor, and long-acting dopamine receptor agonist, in bulk drug and pharmaceutical dosage forms based on its native fluorescence. Method A was based on measuring the fluorescence intensity at 338 nm after excitation at 280 nm. The measured fluorescence was directly proportional to the concentration of the drug over the range of 50.0-450.0 ng/mL with a limit of detection of 14.4 and a limit of quantification of 43.7 ng/mL. The TLC method (method B) was employed on TLC silica gel 60 F254 aluminum sheets previously exposed to concentrated (30-34 %) hydrochloric acid vapor. Ethyl acetate: n-hexane: diethylamine system with a ratio of (10: 3: 1, v/v/v) developing system was used. The retention factor (Rf) of Cabergoline was 0.58 ± 0.03. Linearity was found to be in the range of 100.0-1500.0 ng/band. The LOD and LOQ were 25.4 and 76.9 ng/band, respectively. The methods were validated successfully according to ICH guidelines.

Abstract
PURPOSE In Gonadotropin releasing hormone(GnRH) agonist IVF, after administration of human chorionic gonadotropin(HCG) triggering, there is a risk of ovarian hyperstimulation syndrome(OHSS). Few methods exist to prevent OHSS in these cases. Therefore, we investigated the use of a GnRH antagonist to decrease the risk of OHSS, due to its ability to decrease VEGF production and function. METHOD A retrospective cohort study of 171-IVF patients at risk for developing OHSS after a GnRH agonist cycle with HCG trigger was performed from 2011 to 2019. The patient population consisted of women with an unexpected exuberant response to stimulation based on ovarian reserve testing and were triggered with hCG. Women were converted to a freeze-all cycle and received either cabergoline 0.5 mg orally alone for 7 days from the collection(Group 1, n = 123) or received cabergoline 0.5 mg orally and ganirelix, 250 mcg SC for 7-10 days(Group 2, n = 48). RESULTS Group 1 had more cases of moderate and severe OHSS than group 2-(25% vs. 10% p = 0.03, and 52% vs. 25% p = 0.001 respectively). Group 1 reported more abdominal discomfort and bloating than group 2(91% vs. 65% p < 0.001) and the presence of free fluid was more frequent in group 1 than group 2(74% vs. 35% p < 0.001). Hemoconcentration and electrolyte disturbances were less severe in group 2 than in group 1 (p < 0.001 all cases). CONCLUSION In patients at high risk for developing OHSS after hCG trigger in a GnRH agonist cycle, the addition of GnRH antagonists in the luteal phase may reduce the risk of developing moderate and severe OHSS. The GnRH antagonist likely leads to more rapid luteolysis and down regulation of VEGF production and receptor response, thereby decreasing the hallmark increased vascular permeability.

Abstract
PURPOSE Parasellar ectopic pituitary adenomas (pEPAs) are extremely rare tumors located out of the sella turcica. PEPAs are heterogeneous entities in terms of anatomical localization and secretion of anterior pituitary hormones. METHODS Multicenter retrospective study. Clinical charts' consultation of patients diagnosed with parasellar lesions, to identify all subjects fulfilling the diagnostic criteria of parasellar EPAs. Systematic review of the literature focused on the medical management of prolactin-secreting pEPAs and on the prevalence of radiological bone invasion in pEPAs. RESULTS We identified four cases of pEPAs: (1) 54-year-old female with a prolactin-secreting suprasellar EPA successfully treated with cabergoline; (2) 74-year-old male with a non-functioning EPA of the sphenoidal sinus treated with endoscopic transsphenoidal surgery; (3) 75-year-old female with a giant lesion of the skull base (maximum diameter 7.2 cm) diagnosed as a non-functioning EPA after biopsy; (4) 49-year-old male with a silent corticotroph EPA of the sphenoidal sinus and clivus. Three out of four cases had radiological evidence of invasion of the surrounding bone structures. A systematic review of the literature highlighted that medical therapy can be effective in prolactin-secreting pEPAs. Overall, we found mention of local invasiveness in 65/147 cases (44.2%), confirmed by radiological signs of bone invasion/erosion. CONCLUSION Our experience confirms the heterogeneity of pEPAs in terms of clinical and radiological presentation, as well as hormone secretion. PEPAs show a high frequency of radiological bone invasion, though similar to that of sellar pituitary adenomas. Although extremely rare, pEPAs need to be considered in the differential diagnosis of parasellar lesions.

Abstract
Despite decades of research into the evolutionary drivers of sociality, we know relatively little about the underlying proximate mechanisms. Here we investigate the potential role of prolactin in the highly social naked mole-rat. Naked mole-rats live in large social groups but, only a small number of individuals reproduce. The remaining non-breeders are reproductively suppressed and contribute to burrow maintenance, foraging, and allo-parental care. Prolactin has well-documented links with reproductive timing and parental behaviour, and the discovery that non-breeding naked mole-rats have unusually high prolactin levels has led to the suggestion that prolactin may help maintain naked mole-rat sociality. To test this idea, we investigated whether urinary prolactin was correlated with cooperative behaviour and aggression. We then administered the prolactin-suppressing drug Cabergoline to eight female non-breeders for eight weeks and assessed the physiology and behaviour of the animals relative to controls. Contrary to the mammalian norm, and supporting previous findings for plasma, we found non-breeders had elevated urinary prolactin concentrations that were similar to breeding females. Further, prolactin levels were higher in heavier, socially dominant non-breeders. Urinary prolactin concentrations did not explain variation in working behaviour or patterns of aggression. Furthermore, females receiving Cabergoline did not show any behavioural or hormonal (progesterone) differences, and urinary prolactin did not appear to be suppressed in individuals receiving Cabergoline. While the results add to the relatively limited literature experimentally manipulating prolactin to investigate its role in reproduction and behaviour, they fail to explain why prolactin levels are high in non-breeding naked mole-rats, or how female non-breeding phenotypes are maintained.

Abstract
BACKGROUND Previous studies have described the effects of different drugs in preventing ovarian hyperstimulation syndrome (OHSS). However, the efficacies of those drugs in preventing OHSS remain inconclusive. METHODS We searched the PubMed, Web of Science, Embase, and Cochrane Central Register of Controlled Trials (CENTRAL) databases. A network meta-analysis of randomized controlled trials (RCTs) was performed up to August 2021. We investigated the following drugs in our study: aspirin, albumin, metformin, calcium, cabergoline, quinagolide, letrozole, hydroxyethyl starch (HES), and glucocorticoids. The primary outcome was the incidence rate of moderate-to-severe OHSS, with the results presented as risk ratios (RRs) with 95% confidence intervals (CIs). RESULTS The incidence of moderate-to-severe OHSS was significantly reduced by calcium administration (risk ratios [RR] 0.14, 95% confidence interval [CI]: 0.04, 0.46) (grade: high), HES (RR 0.25, 95% CI 0.07, 0.73) (grade: high), and cabergoline (RR 0.43, 95% CI 0.24, 0.71) (grade: moderate). The surface under the cumulative ranking curve (SUCRA) indicated that calcium (SUCRA, 92.4%) was the most effective intervention for preventing moderate-to-severe OHSS. These drugs were safe and did not affect clinical pregnancy, miscarriage, or live birth rates. CONCLUSION Calcium, HES, and cabergoline could effectively and safely prevent moderate-to-severe OHSS, with calcium as the most effective intervention.

Abstract
Over the last years, the metabolic role of PRL has emerged. PRL excess is known to promote weight gain, obesity, metabolic syndrome, and impairment in gluco-insulinemic and lipid profiles, likely due to the suppression of physiologic dopaminergic tone. Prolactin receptors and dopamine receptors type 2 have been demonstrated to be expressed on both human pancreatic β- cell and adipocytes, supporting a key role of prolactin and dopamine in peripheral metabolic regulation. Medical treatment with the dopamine agonists bromocriptine and cabergoline has been demonstrated to decrease the prevalence of metabolic syndrome and obesity, and significantly improve gluco-insulinemic and lipid profiles. In hyperprolactinemic men with concomitant hypogonadism, correction of hyperprolactinaemia and testosterone replacement has been proven to restore metabolic impairment. In turn, low prolactin levels have also been demonstrated to exert a detrimental effect on weight gain, glucose and lipid metabolism, thus leading to an increased prevalence of metabolic syndrome. Therefore, PRL values ranging from 25 to 100 mg/L, in absence of other recognizable pathological causes, have been proposed to represent a physiological response to the request for an increase in metabolic activity, and nowadays classify the so-called HomeoFIT- PRL as a promoter of metabolic homeostasis. The current review focuses mainly on the effects of hyperprolactinemia and its control by medical treatment with DAs on the modulation of food intake, body weight, gluco-insulinemic and lipid profile. Furthermore, it provides the latest knowledge about the metabolic impact of hypoprolactinemia.

Abstract
OBJECTIVE The first-line treatment for Cushing's disease is transsphenoidal surgery, after which the rates of remission are 60 to 80%, with long-term recurrence of 20 to 30%, even in those with real initial remission. Drug therapies are indicated for patients without initial remission or with surgical contraindications or recurrence, and ketoconazole is one of the main available therapies. The objective of this study was to evaluate the safety profile of and the treatment response to ketoconazole in Cushing's disease patients followed up at the endocrinology outpatient clinic of a Brazilian university hospital. PATIENTS AND METHODS This was a retrospective cohort of Cushing's disease patients with active hypercortisolism who used ketoconazole at any stage of follow-up. Patients who were followed up for less than 7 days, who did not adhere to treatment, or who were lost to follow-up were excluded. RESULTS Of the 172 Cushing's disease patients who were followed up between 2004 and 2020, 38 received ketoconazole. However, complete data was only available for 33 of these patients. Of these, 26 (78%) underwent transsphenoidal surgery prior to using ketoconazole, five of whom (15%) had also undergone radiotherapy; seven used ketoconazole as a primary treatment. Ketoconazole use ranged from 14 days to 14.5 years. A total of 22 patients had a complete response (66%), three patients had a partial response (9%), and eight patients had no response to treatment (24%), including those who underwent radiotherapy while using ketoconazole. Patients whose hypercortisolism was controlled or partially controlled with ketoconazole had lower baseline 24-h urinary free cortisol levels than the uncontrolled group [times above the upper limit of normal: 0.62 (SD, 0.41) vs. 5.3 (SD, 8.21); p < 0.005, respectively] in addition to more frequent previous transsphenoidal surgery (p < 0.04). The prevalence of uncontrolled patients remained stable over time (approximately 30%) despite ketoconazole dose adjustments or association with other drugs, which had no significant effect. One patient received adjuvant cabergoline from the beginning of the follow-up, and it was prescribed to nine others due to clinical non-response to ketoconazole alone. Ten patients (30%) reported mild adverse effects, such as nausea, vomiting, dizziness, and loss of appetite. Only four patients had serious adverse effects that warranted discontinuation. There were 20 confirmed episodes of hypokalemia among 10/33 patients (30%). CONCLUSION Ketoconazole effectively controlled hypercortisolism in 66% of Cushing's disease patients, being a relatively safe drug for those without remission after transsphenoidal surgery or whose symptoms must be controlled until a new definitive therapy is carried out. Hypokalemia is a frequent metabolic effect not yet described in other series, which should be monitored during treatment.

Abstract
INTRODUCTION Prolactin-secreting adenoma (PRLoma) can present as large and invasive neoplasm, with increased markers of cellular proliferation. First-line approach is Dopamine Agonists (DAs) treatment; however, DA-resistance has been reported, especially in male patients. Estrogens induce lactotroph cell replication and PRL secretion: the use of anti-estrogen treatment in patients with PRLoma have been described in few cases. We reported our experience regarding treatment with the aromatase inhibitor anastrozole (ANA) as add-on therapy for male patients with DA resistant PRLoma. MATERIALS AND METHODS We describe four male patients (26, 38, 29 and 19 years old at diagnosis), with PRLoma (median diameter 26 mm, PRL 7730 μg/L). They were resistant to cabergoline (CAB, > 2 mg/week) in terms of PRL secretion and tumor size reduction. ANA 1 mg/day was added to the maximum tolerated dose of CAB for at least 1 year. Magnetic Resonance was performed at baseline, after 6 months of CAB + ANA combination and every 12 months afterward. RESULTS PRL levels decreased in all patients after CAB + ANA (mean - 70%, range - 44/- 97%), achieving a normalization of PRL levels in one case. Tumor size decreased in all cases (mean - 47%, range - 24.5/- 68%). No severe adverse effects have been reported, a moderate weight gain has been observed in two cases. CONCLUSIONS Addition of an aromatase inhibitor (ANA) to the dopamine agonist therapy improved the control of prolactin levels and induced tumour regression.

Abstract
OBJECTIVE To study the outcome of men with macroprolactinoma following cabergoline treatment based on tumour size. DESIGN Retrospective cohort study. METHODS The study included 94 men, divided into three groups according to adenoma diameter: 10-19 mm (Group A, n = 36); 20-39 mm (Group B, n = 41); or ≥40 mm (Group C, giant prolactinomas, n = 17). Patients were followed for a mean of 7.5 years with sellar magnetic resonance imaging, visual fields and hormone measurements. RESULTS Mean baseline prolactin was 767, 2090 and 24,806 ng/ml in Groups A, B and C, respectively (p < .01). Prolactin suppression below three times the upper limit of normal (ULN) was achieved in 34 (94%; mean weekly cabergoline dose of 1.2 mg), 37 (90%; cabergoline dose, 2.1 mg) and 15 (88%; cabergoline dose, 2.8 mg) men (p = .31) in each group. After excluding patients who underwent surgery and radiotherapy, cabergoline suppressed prolactin below three times ULN in 32/35 (91%), 29/37 (78%) and 11/14 (79%) men in Groups A, B and C, respectively (p = .27). Visual deficits were observed in 5 (14%), 12 (29%) and 10 (59%) patients (p < .01); improvement was achieved in 5/5 (100%), 11/12 (92%) and 10/10 (100%) of men in Groups A, B and C. Low baseline testosterone was measured in 26 (72%), 39 (95%) and 17 (100%) patients in the three groups (p < .01). Following multi-modal treatment, hypogonadism persisted in 3 (8%), 5 (12%) and 2 (12%) men, respectively (p = .85). CONCLUSION Macroprolactinomas in men were controlled with cabergoline in 84% of cases, independent of tumour size. Pituitary surgery and adjuvant radiotherapy further improved long-term response to 91%.

Abstract
CONTEXT Somatostatin (SST) and dopamine (DA) inhibit growth hormone (GH) secretion and proliferation of GH-secreting pituitary adenomas (GHomas) through binding to SSTR2 and D2R receptors. Chimeric SST-DA compounds (Dopastatins) display increased potency in inhibiting GH secretion, as compared with individual SST or DA analogs (alone or combined). OBJECTIVE To assess the efficacy of a second-generation dopastatin, TBR-065, in suppressing GH secretion from human GH- and GH/prolactin(PRL)-omas. DESIGN We compared the ability of TBR-065 to inhibit GH secretion from primary cultures of human GH- or GH/PRLoma cells to that of the first generation dopastatin, TBR-760 (formerly BIM-23A760), octreotide (OCT) and cabergoline (CAB), the later either alone or combined. We investigated whether there was any impact of BIM-133, the metabolite of TBR-065, on the ability of TBR-065 to inhibit GH in these cultures. METHODS 17 GH- and GH/PRLomas were included in this study. Inhibition of GH secretion by TBR-065, TBR-760, OCT and CAB (0.1 pM to 0.1 µM) was assessed over a period of 8 h. RESULTS All tumors expressed SSTR2 and D2R mRNAs. GH suppression was higher with TBR-065 as compared with TBR-760 (Emax = 57 ± 5.6% vs. 41.1 ± 12.5%, respectively, p < 0.001) or with OCT + CAB (Emax = 56.8 ± 7.2% vs. 44.4 ± 9.4%, p < 0.001). BIM-133 did not have any impact on the activity of TBR-065. CONCLUSION TBR-065 has significantly improved efficacy in suppressing GH secretion as compared to current available therapies and may represent a new promising option for the treatment of acromegaly.

Abstract
PURPOSE Men with mild to moderate hyperprolactinemia rarely present with normal pituitary on MRI with no visible adenoma, a condition entitled also "idiopathic hyperprolactinemia" or "non-tumoral hyperprolactinemia". We have characterized a cohort of hyperprolactinemic men with normal pituitary imaging. DESIGN We have identified 13 men with true hyperprolactinemia and normal pituitary MRI. Baseline clinical and hormonal characteristics and response to medical treatment were retrospectively retrieved from medical records. RESULTS Mean age at diagnosis was 51 ± 16 years (range, 20-77); mean serum prolactin level at presentation was 91 ng/ml (range, 28-264), eight men presented with low baseline testosterone. Initial complaints leading to diagnosis included sexual dysfunction in ten men and gynecomastia in five. All patients were treated with cabergoline, except for one who was given bromocriptine; none required pituitary surgery. All patients normalized prolactin and testosterone with subsequent clinical improvement reported by most men. Currently, after a mean follow-up of 72 months, ten patients continue treatment with caborgoline (median weekly dose, 0.25 mg), whereas three men discontinued treatment. CONCLUSIONS Men with symptomatic hyperprolactinemia may rarely present with normal pituitary imaging. Medical treatment can lead to hormonal improvement with clinical benefit.

Abstract
OBJECTIVE To present current possibilities of the prevention and therapy of ovarian hyperstimulation syndrome (OHSS). METHODS Literature and guidelines were researched. RESULTS From the view of safety and prevention of OHSS, antagonistic protocol is suitable. Patients with syndrome of polycystic ovaries benefit from the use of metformin or letrozole that can be sufficient to induce ovulation. As a treatment of imminent OHSS, it is recommended to administer 0.5 mg of cabergoline per os daily as well as low molecular weight heparin subcutaneously in prophylactic dose and to maintain sufficient fluid intake. Diuretics are strongly discouraged to use. To maintain intravascular volume, drained ascites can be reintroduced. CONCLUSION We present a review of current literature and recommendations.

Abstract
PURPOSE Cabergoline (CAB) therapy for prolactinomas has been associated with serum IGF-1 levels modifications, with recent reports indicating a paradoxical increase of IGF-1 levels during ongoing therapy. As a result, IGF-1 measurement has been proposed not only at diagnosis of a prolactinoma, but also during follow-up. In this follow-up study on prolactinoma patients with chronic CAB therapy, we investigated whether there are long-term changes in IGF-1 levels that necessitate continuous monitoring. METHODS We reviewed our institutional database on prolactinoma patients with long-term CAB therapy, in whom IGF-1 levels were measured at baseline, at 3-months follow-up and in the long term. RESULTS Chronic CAB therapy was noted in 20 patients (13 men, 7 women). Median (±SD) age was 43.5 ± 12.6 years. 17 (85%) patients presented with a macroprolactinoma. Median CAB treatment time was 75 ± 43 months (range 24-187). Median IGF-1 levels increased at last follow-up, though not significantly; from 122 ± 37 ng/ml (IQR 104-160 ng/ml) to 133 ± 54 (IQR 121-162 ng/ml), p = 0.10. Thereby, 18 (90%) patients showed normal serum IGF-1 levels adjusted for age, one (5%) patient above (1.05 × ULN) and 1 (5%) patient below the normal range (0.34 × ULN). No patient was or became symptomatic of acromegaly. CONCLUSION Our long-term results indicate that chronic treatment with CAB in prolactinoma patients does not significantly modify serum IGF-1 levels. Bearing in mind the sample size of this study, continuing IGF-1 monitoring is not indicated in prolactinoma patients with long-term CAB therapy.

Abstract
OBJECTIVE To report the clinical presentation, management and outcomes of young patients with prolactinomas (<20 years) and conduct a systematic review and meta-analysis. PATIENTS AND DESIGN Clinical, biochemical and radiological data (1996-2018) were collected from our centre. A systematic review and meta-analysis of published literature (1994-2019) on prolactinoma (age <20 years) were conducted. Both random and fixed effects meta-analysis were used to pool outcomes across studies. RESULTS 1 CASE SERIES: Twenty-two patients (14 females) were identified; median age at diagnosis 15.7 years (range 13-19); 12 patients (6 females) had a macroprolactinoma. Seven patients (macroprolactinoma-6) had associated pituitary hormone deficiencies at presentation. Five patients (4 males) underwent surgical resection due to poor response to cabergoline or apoplexy. Patients undergoing surgery had larger tumours (p < .02) and higher serum prolactin concentration (p < .005). All patients with macroprolactinoma >20 mm required surgical intervention. RESULTS 2 SYSTEMATIC REVIEW AND META-ANALYSIS: We selected 11 studies according to strict inclusion criteria describing 275 patients. Macroprolactinoma was more common in girls (78.7% [95% CI 70.5-85.9]) than boys and was more frequent than microprolactinoma (56.6% [95% CI 48.4-64.5]). In males, only 6/57 (10.5%) of tumours were microprolactinoma as compared to 102/198 (51.5%) microprolactinoma in females (risk difference -0.460; [95% CI -0.563 to -0.357]; p < .001). Surgery was first-line therapy in 18.9% patients, with another 15.4% requiring it as a second line (overall 31.3%). CONCLUSIONS Macroprolactinoma, particularly if >20 mm, usually requires multimodal therapy including surgical intervention. While overall prolactinomas in <20 years age group are more common in females, the proportion of macroprolactinoma vs microprolactinoma is greater in males, particularly for large invasive tumours. Microprolactinoma is a rare diagnosis in adolescent males.

Abstract
Severe hypercortisolism is characterized as a life-threatening endocrine condition in patients with Cushing syndrome, usually related to the concomitant onset of one or more comorbidities, requiring rapid normalization of cortisol concentrations and aggressive treatment of associated complications. It is mainly, but not exclusively, caused by ectopic ACTH syndrome, and the diagnosis of severity is more accurate when is based on simultaneous evaluation of the clinical course and manifestations of the disease, cortisol levels and systematic search of comorbidities. Once the severity and imminent risk to life are established, urgent therapeutic measures must be taken and etiological investigation postponed until the patient is stabilized. Adrenal steroidogenesis inhibitors (mainly etomidate, ketoconazole, and metyrapone), alone or in combined therapy, are commonly the first-line treatment for severe hypercortisolemia due to their rapid action, good efficacy and safety profile. The new drug osilodrostat is a future potential candidate to be included in the list. The glucocorticoid receptor antagonist mifepristone has also a rapid action, but its use has been limited due to difficulties to monitor its efficacy and safety. Other slow-acting cortisol-lowering drugs (mainly mitotane, cabergoline, and pasireotide) might be included in the therapeutic scheme to synergize and overcome a possible escape phenomenon frequently observed with the fast-acting drugs in the prolonged follow-up. When medical therapies fail, are unavailable or contra-indicated, bilateral adrenalectomy should be indicated as a life-saving measure. Adrenal arterial embolization is rarely encountered in routine clinical practice, being a last alternative in specialized centers when all other options fail or are contra-indicated.

Abstract
OBJECTIVE The present study aimed to evaluate the efficacy of add-on therapy of cabergoline versus raloxifene to long-acting somatostatin analogues (SAs) in patients with inadequately controlled acromegaly. METHODS This was a prospective, randomized open label clinical trial. Forty-four patients (22 per group) completed the study; where participants received either cabergoline (3 mg/week) or raloxifene (60 mg twice daily) add-on therapy for 12 weeks in a parallel manner. The primary outcome was the rate of reduction in serum insulin-like growth factor 1 (IGF-1) from baseline. Secondary outcomes comprised normalization of serum IGF-1 for age and sex. RESULTS Serum IGF-1 was significantly decreased in both the cabergoline (40.3 ± 25.6%, P<.001) and raloxifene (31.5 ± 24.6%, P<.001) groups, with no significant difference between arms ( P>.05). Normalization in serum IGF-1 values occurred in 40.9% of patients who were on cabergoline compared to 45.5% of those receiving raloxifene ( P = .76). The subsequent logistic regression analysis highlighted baseline IGF-1 as a significant predictor of IGF-1 normalization (odds ratio, 0.995; 95% confidence interval, 0.990-0.999; P = .02). Using the receiver operating characteristic (ROC) curve analysis for the entire group, the baseline IGF-1 value of 1.47 the upper limit of normal (ULN) was the best cut-off point to identify patients with normal IGF-1 at the end of the study (sensitivity: 52.6%, specificity: 84.0%, Yoden's index: 0.366). Full biochemical control of acromegaly was achieved in 22.7% of patients in the cabergoline group compared to 13.6% of those in the raloxifene group ( P = .43). CONCLUSION Cabergoline and raloxifene add-on therapy could effectively decrease serum IGF-1 level in patients with inadequately controlled acromegaly. The efficacy profiles of both drugs are comparable. ABBREVIATIONS DA = dopamine agonist; FBG = fasting blood glucose; GH = growth hormone; IGF1 = insulin-like growth factor-1; IQR = interquartile range; OR = odds ratio; ROC = receiver operating characteristic; SA = somatostatin analogue; SERM = selective estrogen modulator receptor; ULN = upper limit of normal.

Abstract
OBJECTIVE Hyperprolactinemia is common in acromegaly and in these patients, insulin-like growth factor (IGF)-1 level may decrease with dopamine agonist. We report a series of patients with prolactinoma and a paradoxical increase of IGF-1 levels during cabergoline treatment. METHODS Clinical characteristics and response to treatment of patients with prolactinomas, in whom normal or slightly elevated baseline IGF-1 levels increased with cabergoline. RESULTS The cohort consisted of ten prolactinoma patients (nine males, mean age 48 ± 14 years). Mean adenoma size was 23.8 ± 16.2 mm, with cavernous sinus invasion in eight. In five patients baseline IGF-1 levels were normal and in four levels were 1.2-1.5-fold the upper limit of the normal (ULN). One patient had IGF-1 measured shortly after initiating cabergoline and it was 1.4 × ULN. During cabergoline treatment (dose range 0.5-2 mg/week) PRL normalization was achieved in all and tumor shrinkage occurred in seven patients. The mean IGF-1 increase on cabergoline was 1.7 ± 0.4 × ULN. Cabergoline dose reduction or interruption was attempted in five patients and resulted in decreased IGF-1 levels in all, including normalization in two patients. Three patients were eventually diagnosed with acromegaly, one was referred for pituitary surgery followed by complete remission, another patient was switched to somatostatin analogue, and the third was treated by combination of somatostatin analogues with pegvisomant, with reduction of IGF-1 in all these patients. CONCLUSION IGF-1 levels may increase to clinically significant levels during cabergoline treatment for PRL-adenoma. We suggest IGF-1 monitoring in all patients treated with dopamine agonists and not only in those presenting symptoms of acromegaly.

Abstract
OBJECTIVE The aim of this work was to investigate the value of laparoscopic ovarian drilling (LOD) compared with GnRH antagonist flexible protocol combined with cabergoline (Cb), as a prophylaxis against the re-development of ovarian hyperstimulation syndrome (OHSS) in women with clomiphene citrate-resistant polycystic ovary disease (CCR-PCOD) who had severe OHSS before in a previous ICSI cycle. STUDY DESIGN It is a prospective controlled study, where 250 CCR-PCOD women (n = 250) with a history of severe OHSS before, had been recruited for the study. LOD had been performed for 120 (n = 120) of the recruited women before ovarian induction, and considered as group A. GnRH antagonist (Cetrotide 0.25 mg) was added when a leading follicle reaches 14-16 mm combined with oral Cb in a dose 0.5 mg a day before hCG, and for 8 d for another 130 (n = 130) women, and considered as group B. Pregnancy was diagnosed with BhCG level ≥25 IU/L, ± 14 d after embryo transfer, followed with transvaginal ultrasound scanning (TVS) 2 weeks later to confirm intra-uterine pregnancy (IUP). Women were followed up weekly for 3 months for the possible development of any signs and symptoms of OHSS. RESULTS None of the participants in group A developed severe OHSS, and only six women (5%) developed mild to moderate OHSS. The incidence of severe OHSS was significantly higher (n = 3, 15%) in group B compared with group A (p < .001). Another (n = 17, 13.3%) women in group B developed mild to moderate OHSS. The probability of developing severe OHSS was also significantly higher in group B as well (p = .031). Pregnancy rate (PR) was significantly higher in group A more than group B (67% versus 39%, respectively), and all were single intrauterine pregnancies (IUP) and all developed after fresh embryo transfer (ET), compared with frozen embryo transfer (FET) which was performed in 42 cases in group B after postponing ET due to significantly severe OHSS developed. CONCLUSION LOD could be considered a good prophylactic measure against OHSS, in addition to improving the total outcome of IVF cycles in women with CCR-PCOS.

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
BACKGROUND The approach to acromegalic patients with persistent acromegaly after surgery and inadequate response to first-generation somatostatin receptor ligands (SRLs) should be strictly tailored. Current options include new pituitary surgery and/or radiosurgery, or alternative medical treatment with SRLs high dose regimens, pegvisomant (PEG) as monotherapy, or combined therapy with the addition of PEG or cabergoline to SRLs. A new pharmacological approach includes pasireotide, a second-generation SRL approved for patients who do not adequately respond to surgery and/or for whom surgery is not an option. No reports on efficacy and safety of combined therapy with pasireotide and pegvisomant (PEG) in acromegaly are available. CASE PRESENTATION Here we report the case of a 41-year-old acromegalic man with a mixed GH/PRL pituitary adenoma post-surgical resistant to first-generation SRLs both alone and in combination with cabergoline and PEG who achieved biochemical and tumor control with the combined triple treatment with pasireotide, PEG and cabergoline without adverse events and with a good compliance to treatment. CONCLUSIONS Twelve months of therapy with pasireotide, PEG and cabergoline proved to be safe and effective in this particular patient and the clinical improvement of disease resulted in an improved compliance to treatment.

Abstract
Human and animal data indicate that the dopaminergic system plays a crucial role in sexual drive and function. Using a double-blind, placebo-controlled crossover design, this prototype study investigated the effect of the D2 dopamine agonist cabergoline on sexual parameters in 13 healthy women. Cardiovascular and genital parameters were monitored continuously. Sexual drive and function were measured using self-report sexual experience scales. In contrast to previous theories and assumptions, we found that cabergoline did not alter objective and subjective sexual parameters in healthy women. This finding suggests that there may be sex differences in the influence of the dopaminergic system on human sexual functioning.

Abstract
Uterine fibroids (UFs) are the most common tumors of the female genital tract. The effect of UFs on the quality of life and the overall cost of treatment are significant issues worldwide. Tumor size and location are the two specific factors which influence the occurrence of symptoms, the need for, and method of, treatment (some tumors require surgery while some can be treated with selected drugs). Primary prevention and treatment of early UF disease are worthy goals that might have a great impact on health care systems. Several treatments and prophylactic methods can be used in this endeavor. This publication presents current data about lesser-known substances which may have a beneficial effect on the treatment or prophylaxis of UFs and can be administered orally, serving as an alternative to (or complement of) surgery or selective progesterone receptor modulators (SPRMs). Early prevention and treatment of UFs in women from high-risk groups should be our priority. Innovative forms of UF management are under intensive investigation and may be promising options in the near future. Many of them evaluated vitamin D, paricalcitol, epigallocatechin gallate (EGCG), elagolix, aromatase inhibitors (AIs), and cabergoline and deemed them to be safe and effective. The next step in such projects should be properly constructed randomized control trials (RCTs), carried out by successive phases.

Abstract
Presently, the standard of care for prolactinomas, a type of pituitary adenoma, is dopaminergic agents such as bromocriptine and cabergoline. However, dopaminergic agents may induce fibrosis of cardiac valves leading to valvular insufficiency, necessitating surgical treatment of prolactinoma. Fibrosis of prolactinoma can be induced by prolonged medical treatment with bromocriptine, and this usually occurs after years of treatment. In comparison to bromocriptine, there have been no reports of cabergoline-induced fibrosis of prolactinoma. There is a potential for greater emphasis to be placed on assessing the tumour consistency from preoperative MRI scans, or even preoperative contrast-enhanced 3D Fast Imaging Employing Steady-state Acquisition imaging to allow better planning of the surgery. We report a rare case of fibrosis of prolactinoma after cabergoline treatment resulting in its subsequent difficult surgical removal. This patient had early MRI changes of fibrosis of prolactinoma after a short period of 6 months of cabergoline treatment.

Abstract
CONTEXT Acromegaly is characterized by growth hormone (GH) and insulinlike growth factor-1 (IGF-1) hypersecretion, and GH and IGF-1 play important roles in regulating body composition and glucose homeostasis. OBJECTIVE The purpose of our study was to investigate body composition including ectopic lipids, measures of glucose homeostasis, and gonadal steroids in patients with active acromegaly compared with age-, body mass index (BMI)-, and sex-matched controls and to determine changes in these parameters after biochemical control of acromegaly. DESIGN Cross-sectional study of 20 patients with active acromegaly and 20 healthy matched controls. Prospective study of 16 patients before and after biochemical control of acromegaly. MAIN OUTCOME MEASURES Body composition including ectopic lipids by magnetic resonance imaging/proton magnetic resonance spectroscopy; measures of glucose homeostasis by an oral glucose tolerance test; gonadal steroids. RESULTS Patients with active acromegaly had lower mean intrahepatic lipid (IHL) and higher mean fasting insulin and insulin area under the curve (AUC) values than controls. Men with acromegaly had lower mean total testosterone, sex hormone-binding globulin, and estradiol values than male controls. After therapy, homeostasis model assessment of insulin resistance, fasting insulin level, and insulin AUC decreased despite an increase in IHL and abdominal and thigh adipose tissues and a decrease in muscle mass. CONCLUSIONS Patients with acromegaly were characterized by insulin resistance and hyperinsulinemia but lower IHL compared with age-, BMI-, and sex-matched healthy controls. Biochemical control of acromegaly improved insulin resistance but led to a less favorable anthropometric phenotype with increased IHL and abdominal adiposity and decreased muscle mass.

Abstract
CONTEXT The dopamine agonist cabergoline (CAB) has been used widely in the treatment of prolactinomas and other types of pituitary adenomas, but its clinical use is hampered by intolerance in some patients with prolactinoma and lack of effectiveness in other pituitary tumor types. Chloroquine (CQ) is an old drug widely used to treat malaria. Recent studies, including our own, have revealed that CAB and CQ are involved in induction of autophagy and activation of autophagic cell death. OBJECTIVE To test whether CAB and CQ can function cooperatively to suppress growth of pituitary adenomas as well as other cancers. RESULTS In vitro studies using the rat pituitary tumor cell lines MMQ and GH3, human pituitary tumor cell primary cultures, and several human cancer cell lines showed that CQ enhanced suppression of cell proliferation by CAB. These results were confirmed in in vivo xenograft models in nude mice and estrogen-induced rat prolactinomas. To understand the mechanism of combined CAB and CQ action, we established a low-CAB-dose condition in which CAB was able to induce autophagy but failed to suppress cell growth. Addition of CQ to low-dose CAB blocked normal autophagic cycles and induced apoptosis, evidenced by the further accumulation of p62/caspase-8/LC3-II. CONCLUSION The data suggest that combined use of CAB and CQ may increase clinical effectiveness in treatment of human pituitary adenomas, as well as other cancers, making it an attractive option in tumor and cancer therapies.

Abstract
PURPOSE Dopamine agonist (DA) therapy is recommended as the first-line treatment for prolactinomas. However, it requires long treatment duration, and a high recurrence rate after DA withdrawal has been reported. We aimed to elucidate the predictors for long-term remission following DA withdrawal and propose the best candidates who can achieve complete remission after DA withdrawal. METHODS In a retrospective cohort study, we included 89 patients with prolactinoma who have withdrawn DAs with normal prolactin (PRL) levels at Seoul National University Hospital, from 2000 to 2016. Patient's data were retrieved from the electronic medical records. RESULTS The median age and median treatment duration of the study patients were 33 (15-73) years and 69.5 (8.3-277.4) months, respectively. The recurrence rate after drug withdrawal was 57.3% during the 23.9 (3.0-176.8) month follow-up period. Age, gender, baseline PRL level, and baseline maximum tumor diameter were similar between the remission and recurrence group. In the Cox-proportional hazard model analysis, the significant predictors for remission were nadir PRL level of <1 ng/dL (hazard ratio [95% confidence interval] = 0.37 [0.18-0.74]), invisible tumors on magnetic resonance imaging (MRI) (0.42 [0.24-0.74]), and treatment duration of >72 months (0.54 [0.30-0.96]). Of the subjects who met all the three criteria, 66.7% achieved long-term remission. CONCLUSIONS Patients who have no tumor visible on MRI, have a nadir PRL level <1 ng/dL during drug treatment, and received drug treatment for >6 years may be the best candidates for DA withdrawal.

Abstract
We report on a 27-year-old male patient presenting with renal colic secondary to hyperparathyroidism. Further investigations confirmed a diagnosis of type 1 multiple endocrine neoplasia and revealed a 2.0 cm pancreatic neuroendocrine tumour as well as a pituitary macroadenoma with significantly elevated prolactin levels. The patient underwent three-gland parathyroidectomy, a left pancreatectomy, and received dopamine agonist treatment. Genetic testing revealed a novel germline heterozygote missense mutation in the MEN1 gene (p.Gly42Val) which affects the Smad3 binding domain of the MENIN protein. The same mutation was found in the patient's mother, who on further testing was found to have hyperparathyroidism, a pituitary microadenoma and bilateral adrenal hyperplasia without pituitary or adrenal hormone excess. This case report raises the importance of genetic testing for MEN1 syndrome in a patient even when family history appears to be negative. Following genetic counselling, genetic cascade screening should be considered in family members to identify further gene carriers.

Abstract
CONTEXT Insulinlike growth factor I (IGF-I) measurement is essential for the diagnosis and management of growth hormone (GH) disorders. However, patient classification may vary substantially according to the assay technique. OBJECTIVE We compared individual patient data and classifications obtained with six different IGF-I assay kits in a group of patients with various GH disorders. DESIGN In this cross-sectional study, we measured IGF-I with six immunoassays in 102 patients with active or treated acromegaly or GH deficiency. IGF-I normative data previously established for the same six assay kits were used to classify the patients (high, low, or normal IGF-I levels), using both raw data and standard deviation scores (SDSs). Pairwise concordance between assays was assessed with Bland-Altman plots and with the percentage of observed agreement and the weighted κ coefficient for categorized IGF-I SDS. RESULTS We observed marked variability both across each individual's IGF-I raw data and across IGF-I SDS values obtained with each of the six immunoassays. Pairwise concordance between assay values, as assessed with the weighted κ coefficient, ranged from 0.50 (moderate) to 0.81 (excellent). CONCLUSION Even when using normative data obtained in the same large population of healthy subjects and when using calculated IGF-I SDSs, agreement among IGF-I assay methods is only moderate to good. Differences in assay performance must be taken into account when evaluating and monitoring patients with GH disorders. This argues for the use of the same IGF-I assay for a given patient throughout follow-up.

Abstract
OBJECTIVE Prolactinomas are the most common functional pituitary tumour. Dopamine agonists (DA) are its principal treatment. The criteria that should guide therapy withdrawal and the factors that influence disease remission or relapse are not yet fully established. Our purpose is to evaluate the proportion of patients who attempted DA withdrawal, and to identify the factors that influence clinicians to try it. In addition, we aim to study the factors that are involved in prolactinoma remission/relapse after therapy withdrawal. METHODS We retrospectively evaluated 142 patients with prolactinoma diagnosis who had been treated exclusively with DA. Firstly, the patients were divided in two groups, according to whether DA withdrawal had been attempted, or not, and the factors that might predict clinicians' decision to discontinue the therapy were then analysed. Secondly, patients who attempted withdrawal were further divided into two subgroups, based on their remission or relapse status and predictors of remission were evaluated. RESULTS DA withdrawal was attempted in 35.2% of our patients. Females, subjects with lower initial serum prolactin (PRL) levels, those with microadenomas and those with longer treatment duration all had a higher probability of seeing their therapy discontinued. In the withdrawal group, the remission rate was 72%. Macroprolactinomas relapse more often than microprolactinomas (p < 0.05). The recurrence group had higher median initial serum PRL levels and a lower mean duration of therapy, however these variables did not reach statistical significance. CONCLUSION We found a low percentage of attempt of withdrawal of DA therapy in the subjects with prolactinoma. Our data confirms that DA therapy can be discontinued with a high remission rate. Tumour size was the main variable that affected the withdrawal outcome in our patients.

Abstract
Somatostatin analogues and mTOR inhibitors have been used as medical therapy in lung carcinoids with variable results. No data are available on dopamine agonists as treatment for lung carcinoids. The main aim of the current study was to evaluate the effect of the combined treatment of somatostatin analogue octreotide and the dopamine agonist cabergoline with mTOR inhibitors in an in vitro model of typical lung carcinoids: the NCI-H727 cell line. In NCI-H727 cell line, reverse transcriptase-quantitative polymerase chain reaction and immunofluorescence were assessed to characterize the expression of the somatostatin receptor 2 and 5, dopamine receptor 2 and mTOR pathway components. Fifteen typical lung carcinoids tissue samples have been used for somatostatin receptor 2, dopamine receptor 2, and the main mTOR pathway component p70S6K expression and localization by immunohistochemistry. Cell viability, fluorescence-activated cell sorting analysis and western blot have been assessed to test the pharmacological effects of octreotide, cabergoline and mTOR inhibitors, and to evaluate the activation of specific cell signaling pathways in NCI-H727 cell line. NCI-H727 cell line expressed somatostatin receptor 2, somatostatin receptor 5 and dopamine receptor 2 and all mTOR pathway components at messenger and protein levels. Somatostatin receptor 2, dopamine receptor 2, and p70S6K (non phosphorylated and phosphorylated) proteins were expressed in most typical lung carcinoids tissue samples. Octreotide and cabergoline did not reduce cell viability as single agents but, when combined with mTOR inhibitors, they potentiate mTOR inhibitors effect after long-term exposure, reducing Akt and ERK phosphorylation, mTOR escape mechanisms, and increasing the expression DNA-damage-inducible transcript 4, an mTOR suppressor. In conclusion, the single use of octreotide and cabergoline is not sufficient to block cell viability but the combined approach of these agents with mTOR inhibitors might reduce the mTOR inhibitors-induced escape mechanisms and/or activate the endogenous mTOR suppressor, potentiating the effect of the mTOR inhibitors in an in vitro model of typical lung carcinoids.

Abstract
BACKGROUND About 80% of prolactinomas respond to dopamine agonists (DA) with hormonal normalization and tumor shrinkage. Mechanisms of DA resistance include reduction of dopamine receptor subtype 2 (DRD2) expression, short and long isoform ratio and post-receptor mechanisms. It was suggested that polymorphisms in the gene encoding dopamine receptor subtype 2 gene (DRD2) could be associated with variable effectiveness of cabergoline (CAB). OBJECTIVE To assess the influence of DRD2 polymorphisms in responsiveness of CAB treatment in patients with prolactinoma. STUDY DESIGN AND PATIENTS Cross-sectional retrospective case-control study analyzing the frequency of five DRD2 polymorphisms in 148 patients with prolactinoma and 349 healthy subjects. The association of genetic variants and clinical characteristics with CAB responsiveness was performed in 118 patients (mean age at diagnosis 29 years; range 11-61 years) with hormonal evaluation. Patients with prolactin (PRL) normalization were considered as responders. RESULTS No association in genotypes and allele proportions was found comparing patients and controls. On pharmacogenetic study, 118 patients on CAB were included and 20% were non-responders. No association was found between clinical characteristics (gender, age, PRL level and tumor size at diagnosis) and polymorphisms of DRD2 with CAB responsiveness. Otherwise, there was association between polymorphisms rs1076560 (allele A) and rs1800497 (allele T) and the presence of macroadenomas. CONCLUSION No correlation was found between DRD2 polymorphisms and CAB responsiveness in patients with prolactinoma. More data are necessary in order to assess the influence of DRD2 genotyping on DA treatment response.

Abstract
BACKGROUND Ovarian hyperstimulation syndrome (OHSS) is an iatrogenic and potentially life threatening condition resulting from excessive ovarian stimulation. Reported incidence of moderate to severe OHSS ranges from 0.6% to 5% of in vitro fertilization (IVF) cycles. The factors contributing to OHSS have not been completely explained. The release of vasoactive substances secreted by the ovaries under human chorionic gonadotrophin (hCG) stimulation may play a key role in triggering this syndrome. This condition is characterised by a massive shift of fluid from the intravascular compartment to the third space, resulting in profound intravascular depletion and haemoconcentration. OBJECTIVES To assess the effect of withholding gonadotrophins (coasting) on the prevention of ovarian hyperstimulation syndrome in assisted reproduction cycles. SEARCH METHODS For the update of this review, we searched the Cochrane Gynaecology and Fertility Group Trials Register, CENTRAL, MEDLINE (PubMed), CINHAL, PsycINFO, Embase, Google, and clinicaltrials.gov to 6 July 2016. SELECTION CRITERIA We included only randomized controlled trials (RCTs) in which coasting was used to prevent OHSS. DATA COLLECTION AND ANALYSIS Two review authors independently selected trials and extracted data. They resolved disagreements by discussion. They contacted study authors to request additional information or missing data. The intervention comparisons were coasting versus no coasting, coasting versus early unilateral follicular aspiration (EUFA), coasting versus gonadotrophin releasing hormone antagonist (antagonist), coasting versus follicle stimulating hormone administration at the time of hCG trigger (FSH co-trigger), and coasting versus cabergoline. We performed statistical analysis in accordance with Cochrane guidelines. Our primary outcomes were moderate or severe OHSS and live birth. MAIN RESULTS We included eight RCTs (702 women at high risk of developing OHSS). The quality of evidence was low or very low. The main limitations were failure to report live birth, risk of bias due to lack of information about study methods, and imprecision due to low event rates and lack of data. Four of the studies were published only as abstracts, and provided limited data. Coasting versus no coastingRates of OHSS were lower in the coasting group (OR 0.11, 95% CI 0.05 to 0.24; I² = 0%, two RCTs; 207 women; low-quality evidence), suggesting that if 45% of women developed moderate or severe OHSS without coasting, between 4% and 17% of women would develop it with coasting. There were too few data to determine whether there was a difference between the groups in rates of live birth (OR 0.48, 95% CI 0.14 to 1.62; one RCT; 68 women; very low-quality evidence), clinical pregnancy (OR 0.82, 95% CI 0.46 to 1.44; I² = 0%; two RCTs; 207 women; low-quality evidence), multiple pregnancy (OR 0.31, 95% CI 0.12 to 0.81; one RCT; 139 women; low-quality evidence), or miscarriage (OR 0.85, 95% CI 0.25 to 2.86; I² = 0%; two RCTs; 207 women; very low-quality evidence). Coasting versus EUFAThere were too few data to determine whether there was a difference between the groups in rates of OHSS (OR 0.98, 95% CI 0.34 to 2.85; I² = 0%; 2 RCTs; 83 women; very low-quality evidence), or clinical pregnancy (OR 0.67, 95% CI 0.25 to 1.79; I² = 0%; 2 RCTs; 83 women; very low-quality evidence); no studies reported live birth, multiple pregnancy, or miscarriage. Coasting versus antagonistOne RCT (190 women) reported this comparison, and no events of OHSS occurred in either arm. There were too few data to determine whether there was a difference between the groups in clinical pregnancy rates (OR 0.74, 95% CI 0.42 to 1.31; one RCT; 190 women; low-quality evidence), or multiple pregnancy rates (OR 1.00, 95% CI 0.43 to 2.32; one RCT; 98 women; very low-quality evidence); the study did not report live birth or miscarriage. Coasting versus FSH co-triggerRates of OHSS were higher in the coasting group (OR 43.74, 95% CI 2.54 to 754.58; one RCT; 102 women; very low-quality evidence), with 15 events in the coasting arm and none in the FSH co-trigger arm. There were too few data to determine whether there was a difference between the groups in clinical pregnancy rates (OR 0.92, 95% CI 0.43 to 2.10; one RCT; 102 women; low-quality evidence). This study did not report data suitable for analysis on live birth, multiple pregnancy, or miscarriage, but stated that there was no significant difference between the groups. Coasting versus cabergolineThere were too few data to determine whether there was a difference between the groups in rates of OHSS (OR 1.98, 95% CI 0.09 to 5.68; P = 0.20; I² = 72%; two RCTs; 120 women; very low-quality evidence), with 11 events in the coasting arm and six in the cabergoline arm. The evidence suggested that coasting was associated with lower rates of clinical pregnancy (OR 0.38, 95% CI 0.16 to 0.88; P = 0.02; I² =0%; two RCTs; 120 women; very low-quality evidence), but there were only 33 events altogether. These studies did not report data suitable for analysis on live birth, multiple pregnancy, or miscarriage. AUTHORS' CONCLUSIONS There was low-quality evidence to suggest that coasting reduced rates of moderate or severe OHSS more than no coasting. There was no evidence to suggest that coasting was more beneficial than other interventions, except that there was very low-quality evidence from a single small study to suggest that using FSH co-trigger at the time of HCG administration may be better at reducing the risk of OHSS than coasting. There were too few data to determine clearly whether there was a difference between the groups for any other outcomes.

Abstract
PURPOSE Remission of acromegaly has been reported after somatostatin analogs withdrawal, but not after withdrawal of combination therapy with cabergoline, and only in case reports of patients controlled by cabergoline alone. METHODS To establish the remission rates (normal IGF-1 for age/sex: IGF-1 ≤ 1.00 xULN) after withdrawal of combined treatment with octreotide LAR and cabergoline and of cabergoline alone, we prospectively studied 16 patients with acromegaly controlled by those treatments in the preceding 2 years as part of a larger study on remission of acromegaly after withdrawal of different medical treatments. RESULTS Among 97 patients with controlled acromegaly included in the entire study, only 16 patients had been on combination therapy (n = 12) or cabergoline alone (n = 4). At 8 weeks after treatment withdrawal, three patients (19%) were in remission (short-term remission). At 60 weeks (long-term remission), IGF-1 levels were still in the normal range in two patients (12.5%) and remained normal up to 108 weeks after treatment withdrawal (last visit). One patient had been treated with cabergoline alone and another one with combination of octreotide and cabergoline before treatment withdrawal. CONCLUSION Remission of acromegaly after treatment withdrawal seems to be uncommon in patients controlled by cabergoline, either as monotherapy or in combination with octreotide. In the future, larger studies and/or meta-analysis will be necessary to accurately establish the remission rates of acromegaly after withdrawal of cabergoline with or without somatostatin analogs.

Abstract
Hyperprolactinemia and prolactinomas cause infertility in significant number of women. But, pregnancy may lead to post-partum remission of hyperprolactinemia. The data on pregnancy and tumor outcome in women with macroprolactinoma conceiving on Cabergoline (CAB) therapy is increasing but still less than with Bromocriptine. We studied the incidence of fetal malformations, hyperprolactinemia and tumor course after gestation in infertile women harboring macroprolactinoma, who conceived on CAB therapy during the year 2005-2015. The cohort was divided into two groups based on the continuation of CAB therapy during gestation (Group A) or not (Group B). Forty-eight pregnancies in 33 women were recorded. CAB was continued throughout gestation in 25 pregnancies (Group A). The incidence of missed abortion (8.3%), still birth (4.2%) and low birth weight (7.7%) were not different in two groups. Neural tube defects were observed in 3 pregnancies (all in Group A). Post-partum, recurrence of hyperprolactinemia was observed in 64.6% and 60.9% (p = 0.8) of women in group A and B, respectively. Cabergoline was restarted after 60% and 60.9% (p = 0.9) pregnancies in the two groups in view of symptomatic hyperprolactinemia and/or persistence of macroadenoma. Post-partum, recurrence of hyperprolactinemia is common in spite of significant tumor reduction in infertile women with macroprolactinoma. Continuation of CAB during gestation does not influence the post-pregnancy recurrence of hyperprolactinemia or tumor remission.

Abstract
BACKGROUND Prolactinomas are the commonest functional tumors of the pituitary gland. There are still controversies regarding medical therapy in specific clinical situations. Patients may be managed by different specialists in the Middle East and North Africa (MENA) region and no data exist on patterns of clinical management. OBJECTIVES To ascertain the diagnostic and therapeutic approaches to prolactinomas among relevant professionals from the MENA region. METHODS An online survey of a large sample of physicians was conducted. The questionnaire covered various aspects of diagnosis and treatment of prolactinomas. 468 respondents were included; 36 % were endocrinologists; 49 % worked in public facilities and 81 % graduated more than 10 years. 40 and 30 % would have seen 1-5 and more than 5 suspected or confirmed prolactinomas over a 6 months period, respectively. RESULTS Regarding the diagnosis, 30 % of the respondents considered that prolactin levels <100 ng/ml exclude the presence of a prolactinoma. 21 % of respondents considered prolactin levels >250 ng/ml compatible with macroprolactinomas only, whereas others accepted this to be compatible also with microprolactinomas, macroprolactinaemia and drug-induced hyperprolactinemia (50, 42 and 36 % respectively). 71 % of respondents favored the screening for macroprolactin in asymptomatic individuals with hyperprolactinemia. Regarding the treatment, 84 % of respondents would treat microprolactinomas even in the absence of symptoms whereas 72 % of the respondents would treat microprolactinomas only if symptoms exist. 60 and 49 % of the respondents chose cabergoline as the drug of choice to treat macroprolactinomas and microprolactinomas respectively. Similar proportions had no preference of either cabergoline or bromocriptine as the best treatment for macroprolactinoma (27 %) and microprolactinomas (32 %). 46 and 75 % of respondents favored treatment withdrawal 2-3 years after prolactin normalization in patients with macroprolactinomas and microprolactinomas, respectively whereas 10 % of respondents withdraw treatment after menopause in either case. 94 % of respondents considered medical therapy as the primary treatment for microprolactinomas. In case of pregnancy, 49 % considered bromocriptine as the drug of choice for women who wish to become pregnant. 65 and 38 % of respondents advocated discontinuation of treatment with dopamine agonists in patients with microprolactinomas and macroprolactinomas, respectively. Finally, 48 % would allow breast-feeding without restriction, 28 % would restrict it to patients with microprolactinomas and 25 % would not recommend it for women with prolactinomas. CONCLUSIONS This is the first study of the clinical management of prolactinomas in the MENA region. Some of the practices are not in line with the latest Endocrine and Pituitary Societies guidelines. These warrant further discussions of contemporary guidelines in regional forums.

Abstract
OBJECTIVE To assess the outcome of using low-dose aspirin, dopamine agonist and triggering ovulation by low dose of HCG in combination with GnRH agonist in fixed GnRH antagonist protocol in patients at risk of OHSS. STUDY DESIGN This prospective cohort study was conducted on 50 infertile women who were at high risk of OHSS. They received low dose aspirin from first day of stimulation, cabergoline 0.5mg daily from the day of HCG for 8days and low dose of HCG (2500 IU) in combination with GnRH agonist for final oocyte maturation in fixed GnRH antagonist protocol. RESULTS The study was conducted on 50 cases and all of them completed the study protocol. The clinical pregnancy rate was 40% (20 cases of 50) and no cases developed severe or critical OHSS. Only 8% (4 cases) developed moderate OHSS. CONCLUSION Combining aspirin, cabergoline, and triggering with low dose of HCG in combination with GnRH agonist produced excellent clinical pregnancy rate, and decreased hospital admissions with severe or critical OHSS.

Abstract
OBJECTIVE The efficacy of cabergoline in Cushing's disease (CD) is controversial. The aim of this study was to assess the efficacy and tolerability of cabergoline in a large contemporary cohort of patients with CD. DESIGN We conducted a retrospective multicenter study from thirteen French and Belgian university hospitals. METHODS Sixty-two patients with CD received cabergoline monotherapy or add-on therapy. Symptom score, biological markers of hypercortisolism and adverse effects were recorded. RESULTS Twenty-one (40%) of 53 patients who received cabergoline monotherapy had normal urinary free cortisol (UFC) values within 12 months (complete responders), and five of these patients developed corticotropic insufficiency. The fall in UFC was associated with significant reductions in midnight cortisol and plasma ACTH, and with clinical improvement. Compared to other patients, complete responders had similar median baseline UFC (2.0 vs 2.5xULN) and plasma prolactin concentrations but received lower doses of cabergoline (1.5 vs 3.5 mg/week, P < 0.05). During long-term treatment (>12 months), cabergoline was withdrawn in 28% of complete responders because of treatment escape or intolerance. Overall, sustained control of hypercortisolism was obtained in 23% of patients for 32.5 months (19-105). Nine patients on steroidogenesis inhibitors received cabergoline add-on therapy for 19 months (1-240). Hypercortisolism was controlled in 56% of these patients during the first year of treatment with cabergoline at 1.0 mg/week (0.5-3.5). CONCLUSIONS About 20-25% of CD patients are good responders to cabergoline therapy allowing long-term control of hypercortisolism at relatively low dosages and with acceptable tolerability. No single parameter, including the baseline UFC and prolactin levels, predicted the response to cabergoline.

Abstract
OBJECTIVE Both antitumor and antisecretory efficacies of dopamine agonists (DA) make them the first-line treatment of macroprolactinomas. However, there is no guideline for MRI follow-up once prolactin is controlled. The aim of our study was to determine whether a regular MRI follow-up was necessary in patients with long-term normal prolactin levels under DA. PATIENTS AND METHODS We conducted a retrospective multicenter study (Marseille, Paris La Pitie Salpetriere and Nancy, France; Liege, Belgium) including patients with macroprolactinomas (largest diameter: >10 mm and baseline prolactin level: >100 ng/mL) treated by dopamine agonists, and regularly followed (pituitary MRI and prolactin levels) during at least 48 months once normal prolactin level was obtained. RESULTS In total, 115 patients were included (63 men and 52 women; mean age at diagnosis: 36.3 years). Mean baseline prolactin level was 2224 ± 6839 ng/mL. No significant increase of tumor volume was observed during the follow-up. Of the 21 patients (18%) who presented asymptomatic hemorrhagic changes of the macroprolactinoma on MRI, 2 had a tumor increase (2 and 7 mm in the largest size). Both were treated by cabergoline (1 mg/week) with normal prolactin levels obtained for 6 and 24 months. For both patients, no further growth was observed on MRI during follow-up at the same dose of cabergoline. CONCLUSION No significant increase of tumor size was observed in our patients with controlled prolactin levels on DA. MRI follow-up thus appears unnecessary in patients with biologically controlled macroprolactinomas.
