Since 2005, the Cleveland Clinic Foundation has held an annual symposium addressing contemporary issues in pituitary disease. The faculty includes Cleveland Clinic Foundation staff, physicians and invited specialists, and the presentations are case-based with frequent audience response in order to be of real value in terms of the issues that may occur in day-to-day clinical practice relating to pituitary disease. This brief meeting report summarizes the key points arising from this interactive format. Read More

Human growth hormone (GH) is a classical pituitary endocrine hormone that is essential for normal postnatal growth and has pleiotropic effects across multiple physiological systems. GH is also expressed in extrapituitary tissues and has localized autocrine/paracrine effects at these sites. In adults, hypersecretion of GH causes acromegaly, and strategies that block the release of GH or that inhibit GH receptor (GHR) activation are the primary forms of medical therapy for this disease.

Objectives: The ACROSTART study was intended to determine the time to achieve normalization of GH and IGF-I levels in responding patients with acromegaly administered different dosage regimens of lanreotide Autogel (Somatuline Autogel).

Methods: From March 2013 to October 2013, clinical data from 57 patients from 17 Spanish hospitals with active acromegaly treated with lanreotide for ≥4 months who achieved hormonal control (GH levels <2.5ng/ml and/or normalized IGF-I levels in ≥2 measurements) were analyzed. Read More

The GH-receptor antagonist pegvisomant (PEG) reduces peripheral IGF-1 synthesis and is used to treat acromegaly patients resistant or intolerant to somatostatin analogues (SSA). Medical therapy is generally life-long in patients with acromegaly, since disease remission is very uncommon after SSA discontinuation and has never been reported after PEG withdrawal. Here, we report for the first time the cases of two acromegaly patients treated with PEG monotherapy for many years because of resistance to SSA, who persistently maintained normal serum IGF-1 levels after PEG withdrawal.

Filamin-A (FLNA) plays a crucial role in somatostatin receptor (sst) subtype-2 signaling in somatotropinomas. Our objective was to investigate the in vivo association between FLNA and sst2 expression, sst5 expression, dopamine receptor subtype-2 (D2) expression, somatostatin receptor ligand (SRL) responsiveness and tumor invasiveness in somatotropinomas. Quantitative real-time PCR was used to evaluate the absolute mRNA copy numbers of FLNA/sst2/sst5/D2 in 96 somatotropinomas. Read More

Objective: Long-term effects of endoscopic endonasal transsphenoidal intracapsular debulking and adjuvant somatostatin analogs were evaluated in patients with growth hormone secreting pituitary macroadenomas.

Methods: We retrospectively reviewed the medical records of 45 patients with acromegalic macroadenoma who underwent endonasal endoscopic transsphenoidal intracapsular debulking and received adjuvant somatostatin analogs (octreotide) between 2006 and 2015, who had more than 1 year of follow-up. To evaluate the predictive factors for 1 year and long-term biochemical outcomes, univariate and multivariate analyses were performed. Read More

X-linked acrogigantism (XLAG) is a recently described early-onset gigantism due to GPR101 duplication that induces growth hormone (GH) oversecretion. GPR101, which belongs to Family A rhodopsin-like family of G protein-coupled receptors, is predominantly expressed in hypothalamus and pituitary, suggesting that GPR101 might be important in regulating diverse functions such as energy balance and reproduction. Most mammalian GPR101s have extremely long third intracellular loops (ICL3); however, zebrafish GPR101 has a much shorter ICL3, but a longer C-terminus. Read More

Objective: In acromegaly, both lipotoxicity secondary to GH excess and insulin resistance have a significant impact on the liver. Ultrasonography has shown poor sensitivity in detecting hepatic steatosis and noninvasive methods have been proposed. We evaluated the hepatic steatosis index (HSI), a validated surrogate index of hepatic steatosis, and we correlated it with disease activity and insulin resistance. Read More

Acromegaly is a chronic systemic disease mainly caused by a growth hormone (GH)- secreting pituitary neuroendocrine tumor (PitNETs), which is associated with many health complications and increased mortality when not adequately treated. Transsphenoidal surgery is considered the treatment of choice in GH-secreting PitNETs, but patients in whom surgery cannot be considered or with persistent disease after surgery require medical therapy. Treatment with available synthetic somatostatin analogues (SSAs) is considered the mainstay in the medical management of acromegaly which exert their beneficial effects through the binding to a family of G-protein coupled receptors encoded by 5 genes (SSTR1- 5).

Primary hyperparathyroidism is among the most common causes of hypercalcemia. However, ingestion of medication, including hydrochlorathiazide, lithium, and foscarnet, excessive vitamin A ingestion, endocrinopathies such as hyperthyroidism, adrenal insufficiency, and acromegaly, abnormal nutrient intake such as parenteral nutrition in preterm infants and milk-alkali syndrome, and prolonged immobilization have all been associated with hypercalcemia. The most common cause of nonparathyroid hypercalcemia is neoplasia. Read More

The prevalence of GH-secreting pituitary tumors in domestic cats () is 10-fold greater than in humans. The predominant inhibitory receptors of GH-secreting pituitary tumors are somatostatin receptors (SSTRs) and D dopamine receptor (DRD2).

Excess growth hormone (GH) secretion in acromegaly patients results in increased levels of IGF-1 expression, which causes the clinical manifestations of acromegaly. IGF-1 levels are attenuated by IGFBP3, and a polymorphism in the promoter of IGFBP3 is known to affect the circulating level of IGFBP3 protein. The aim of the study was to evaluate the association of the gene polymorphism with clinical features and surgery outcomes in acromegaly. Read More

Thyrotropin (TSH)-secreting pituitary tumors are the rarest functioning pituitary tumors. Nonetheless, they are not infrequently plurihormonal, as they may express/secrete hormones made by other pituitary cells derived from the Pit-1 lineage such as growth hormone (GH), prolactin (PRL), and α-subunit (αSU). However, adrenocorticotropin (ACTH) or gonadotropin secretion by such a tumor is exceptional. Read More

Context: Pegvisomant, a growth hormone receptor (GHR) antagonist, is a well-known drug that was designed to treat acromegaly. However, recent studies have indicated that the GHR is a "moonlighting" protein that may exhibit dual functions based on its localization in the plasma membrane and nucleus. In light of this finding, we explored whether pegvisomant is a potential "moonlighting" GHR antagonist. Read More

BACKGROUND The clinical presentation in acromegaly is usually insidious, with headaches or visual disturbances being the most common symptoms. Previous studies have shown higher fibrinogen levels, lower protein C and S activity values, and enhanced platelet function in patients with acromegaly compared to a normal population. Nevertheless, the link between hypercoagulability and acromegaly is often overlooked and rarely reported in the literature. Read More

Silent somatotroph pituitary neuroendocrine tumors (or silent growth hormone pituitary neuroendocrine tumors, SGH-PitNET) are neoplasias with positive immunostaining for growth hormone (GH), in patients with no signs and symptoms of acromegaly nor biochemical evidence of GH hypersecretion. From a clinical stand-point they are considered and managed as non-functioning pituitary tumors, since they usually come to evidence due to mass-effects (headache, visual impairment, hypopituitarism) or as asymptomatic pituitary incidentalomas. SGH-PitNET have deserved little attention in the medical literature, and no specific guidelines exist regarding their management. Read More
