We present the clinical case of a patient who was admitted with an onset of diabetes mellitus (DM) with associated ketosis and whose clinical, hormonal, and radiological evolution revealed the presence of primary hyperparathyroidism, pancreatic neuroendocrine tumor, and GH-producing pituitary macroadenoma in the context of multiple endocrine neoplasia type 1 (MEN1). DM is relatively common in cases of acromegaly, but it is not generally associated with ketosis. Simultaneously, the patient presented a meningioma, which is associated with pituitary macroadenoma only in extremely rare cases...

A young man with subtle clinical features suggestive of hypersomatotropism presented with acute-onset severe headache. Relevant investigations confirmed polycythaemia and growth hormone (GH)-secreting pituitary macroadenoma with apoplexy. Secondary polycythaemia and myeloproliferative disorders were ruled out. At follow-up after 3 months, resolution of polycythaemia and acromegaly was observed, evident on normal haemoglobin levels, a normocellular marrow, and normal insulin-like growth factor-1 (IGF-1) with glucose-suppressed GH levels...

PURPOSE: Measuring IGF-1, a biomarker for GH activity, is critical to evaluating disordered hypothalamic-pituitary GH axis. Inconsistent IGF-1 measurements among different immunoassays are well documented. We switched from Immulite 2000 immunoassay to narrow-mass-extraction, high-resolution liquid chromatography mass-spectrometry (LC-MS) compliant with recent consensus recommendations on assay standardization. Comparability of these two assays in patients with pituitary disease in a clinical practice setting is not known...

BACKGROUND: Isolated absent thelarche is a rare condition that is infrequently reviewed in the literature. CASE: A 28-year-old woman with neurofibromatosis type 1 and acromegaly presented with absent breast development despite hormone therapy. Examination noted a normally developed woman with acromegalic features and Tanner stage I breasts. Hormone studies and karyotype were normal. Magnetic resonance imaging of the patient's brain demonstrated a voluminous pituitary...

CONTEXT: The high risk of vertebral fractures (VFs) in acromegaly patients despite normal bone mineral density (BMD) is well known. The reasons for this paradoxical finding of skeleton fragility are poorly understood due to the limited data on bone histomorphometry in acromegaly. OBJECTIVE: This study aimed to analyze histomorphometric parameters including bone microarchitecture in acromegaly patients with VFs and normal BMD compared to normal subjects, and also to evaluate the differences between active and controlled acromegaly patients...

Primary neuroendocrine tumors of the thymus (NETTs) are rare and biologically very aggressive neoplasms, usually located in the anterior mediastinal space. They are more frequently observed in males, in their fourth/fifth decades of life. In 50% of cases, NETTs are associated with endocrinopaties [Cushing's syndrome, acromegaly or Multiple Endocrine Neoplasia-1 (MEN-1) syndrome]. NETTs very often present with invasion of the surrounding mediastinal anatomical structures. Surgery, even in advanced stages, is the mainstay of treatment: a compete resection through a median sternotomy or a combined access (sternotomy + thoracotomy) should be always attempted...

BACKGROUND: This pilot study was carried to determine the prevalence of retinopathy, especially proliferative retinopathy, in patients with acromegaly. METHODS: We analyzed 43 acromegalic patients and 129 age- and gender-matched patients with type 2 diabetes. The retinopathy status was determined from the medical records based on the ophthalmologist consultations of patients with acromegaly. Color photographs of the macula- and disc-centered views were obtained at an angle of 45° with a fundus camera after pharmacologic-induced mydriasis in patients with type 2 diabetes...

The skin serves as a window for clinicians to understand, diagnose, and monitor endocrine disease. Dermatologic manifestations of endocrinopathies contribute significantly to an individual's health and quality of life. In this review, we outline various disorders of the hypothalamic-pituitary axis, thyroid gland, pancreas, adrenal gland, and androgen axis as well as hereditary endocrine syndromes. In acromegaly, glycosaminoglycan deposition contributes to a thickening of skin and soft tissue, which manifests as coarsening and enlargement of facial and acral structures...

Aim: To assess the efficacy and safety of pasireotide long-acting release (PAS-LAR) alone or in combination with pegvisomant by switching acromegaly patients who were well-controlled with somatostatin analogues (LA-SSAs) and pegvisomant to PAS-LAR with or without pegvisomant. Methods: 61 acromegaly patients were enrolled in a prospective open-label study. We included patients with an IGF-I ≤1.2 x Upper Limit of Normal (ULN) during treatment with LA-SSAs and pegvisomant...

OBJECTIVE: We aimed to determine the long-term effects of Gamma knife radiosurgery (GKS) on remnants in the cavernous sinus (CS) after transsphenoidal surgery (TSS) for acromegaly and to identify its possible adverse effects. METHODS: Thirty patients who had remnant tumors only inside the CS after TSS and who consequently underwent GKS were included. They were followed for a median period of 47 months after GKS with regular hormonal and radiological examinations...

A 60-year-old man with a pre-existing stable sacrococcygeal teratoma developed acromegaly, ectopic Cushing's syndrome, and 5HIAA secretion. To our knowledge, this represents the first reported case of ACTH and serotonin secretion, and likely GHRH or GH cosecretion, from a sacrococcygeal teratoma in an adult.

Background/aim: Acromegaly is often associated with obstructive sleep apnea syndrome (OSAS) with a frequency between 40% and 80%. The aim of the present study was to evaluate the clinical and polysomnographic characteristics of acromegaly patients with sleep apnea symptoms and to identify positive airway pressure (PAP) adherence in acromegaly patients with OSAS diagnosis.Materials and methods: Twenty-eight well-controlled acromegaly patients (17 males, mean age 48.7 ± 10.1 years) with sleep apnea symptoms were included in this prospective study...

The study aimed to assess the economic burden, health-related quality of life (HRQoL), and acromegaly treatment satisfaction in the USA. A web-based, cross-sectional survey was distributed to members of Acromegaly Community. Data related to comorbidities, treatment patterns, and treatment satisfaction were collected. The costs over the past 3 months included out-of-pocket cost, sick leave, leave of absence, direct loss of job due to acromegaly, unemployment, assistance to perform household chores, and family member loss of income...

BACKGROUND: Patients with acromegaly have 2-3 times the expected mortality rates primarily due to cardiovascular risks. Echocardiographic studies showing improvement of cardiac function following transsphenoidal surgery (TSS) are limited. MATERIALS AND METHODS: All patients with acromegaly underwent preoperative echocardiography and tissue Doppler (Philips i33, 3D ECHO) for assessment of cardiac indices. In the prospective group of patients, echocardiography was repeated after 6 months of surgery...

The impact of acromegaly on bone and the risk of fractures has not been sufficiently investigated. GH hypersecretion stimulates bone turnover, leading to an increase in bone turnover markers. Normal or even increased bone mineral density (BMD) in comparison to healthy controls have been reported, but there are some works where decreased BMD was observed among acromegaly patients with hypogonadism, particularly at lumbar spine. Less pronounced effect of GH overproduction was observed at the femoral neck, as explained by the positive effect of hypersecretion on the cortical bone (due to periosseal ossification)...

PURPOSE: Octreotide (OCT) has been successfully used for treatment of acromegaly and neuroendocrine tumors for more than 30 years. However, long-term safety of OCT has not been documented in placebo-controlled setting. This present analysis pooled safety data from two similarly-designed, randomized, and placebo-controlled studies to evaluate long-term safety of long-acting OCT (20, 30 mg); targeted post-hoc analyzes focused on cardiac, hepatic, and renal safety. METHODS: Two studies (NCT00131144, NCT001308450) were conducted in patients with diabetic retinopathy (OCT20 = 191, OCT30 = 348, placebo = 347)...
