Metabolic Complications of Acromegaly.

Front Horm Res 2018 5;49:20-28. Epub 2018 Apr 5.

Diabetes is recognized as one of the most common acromegaly co-morbidities with a prevalence ranging 20-53%, while over one-third of these patients have an altered lipid profile. In fact, as in the non-acromegalic population, carbohydrate and lipid metabolism abnormalities are closely linked. Long term exposure to an excess of growth hormone (GH) and Insulin-like growth factor-1 concentrations results in insulin resistance and an increased hepatic glucose production. Read More

Reduced protein expression of the phosphodiesterases PDE4A4 and PDE4A8 in AIP mutation positive somatotroph adenomas.

Mol Cell Endocrinol 2018 May 3. Epub 2018 May 3.

Centre for Endocrinology of Queen Mary, University of London, London EC1M 6BQ, UK. Electronic address:

Type 4 phosphodiesterases (PDE4s) of the large PDE enzyme superfamily have unique specificity for cAMP and may, therefore, be relevant for somatotroph tumorigenesis. Somatotroph adenomas typically overexpress PDEs probably as part of a compensatory mechanism to reduce cAMP levels. The rat PDE4A5 isoform (human homolog PDE4A4) interacts with the AIP protein, coded by a tumour suppressor gene mutated in a subgroup of familial isolated pituitary adenomas (FIPAs). Read More

Pituitary Diseases and Bone.

Endocr Rev 2018 Apr 19. Epub 2018 Apr 19.

Chair of Endocrinology, Università Vita-Salute San Raffaele, Milan, Italy.

Neuroendocrinology of bone is a new area of research based on the evidence that pituitary hormones may directly modulate bone remodeling and metabolism. Skeletal fragility associated with high risk of fractures is a common complication of several pituitary diseases such as hypopituitarism, Cushing disease, acromegaly and hyperprolactinemia. As in other forms of secondary osteoporosis, pituitary diseases generally affect bone quality more than bone quantity and fractures may occur even in the presence of normal or low-normal bone mineral density as measured by dual-energy X-ray absorptiometry, making difficult the prediction of fractures in these clinical settings.

Cystic tumors of the pituitary infundibulum: seminal autopsy specimens (1899 to 1904) that allowed clinical-pathological craniopharyngioma characterization.

Pituitary 2018 Apr 21. Epub 2018 Apr 21.

Department of Pathology and Clinical Bacteriology, Jakob Erdheim Institute, Vienna, Austria.

A heterogeneous group of epithelial cystic tumors developed at the infundibulum and the third ventricle disconcerted pathologists at the dawn of the twentieth century. Very little was known at that time about the physiological role played by the pituitary gland, and there was almost complete ignorance regarding the function of the hypothalamus. Acromegaly, or enlargement of acral body parts, described in 1886 by Pierre Marie, was the only disease linked to primary hypertrophies of the pituitary gland, known as "pituitary strumas".

Endocrine Remission After Pituitary Stereotactic Radiosurgery: Differences in Rates of Response for Matched Cohorts of Cushing Disease and Acromegaly Patients.

Int J Radiat Oncol Biol Phys 2018 Jul 20;101(3):610-617. Epub 2018 Feb 20.

Department of Neurological Surgery, University of Virginia, Charlottesville, Virginia; Department of Radiation Oncology, University of Virginia, Charlottesville, Virginia.

Purpose: To compare and describe the time to endocrine remission and new hypopituitarism among patients with growth hormone (GH) and adrenocorticotropic hormone (ACTH)-secreting pituitary adenomas after radiosurgery, controlling for several known prognostic factors.

Methods And Materials: An institutional review board-approved, institutional retrospective analysis of patients with GH- and ACTH-secreting pituitary adenomas was performed, with matching for patient sex, age at radiosurgery, interval between the last resection and radiosurgery, use of previous radiation therapy, whole sella treatment, suprasellar extension, cavernous sinus invasion, and margin dose. Endocrine remission was defined as a normal serum insulin-like growth factor-1 (GH secreting) or a normal 24-hour urine-free cortisol (ACTH secreting) level without suppressive medications.

Association between radiological parameters and clinical and molecular characteristics in human somatotropinomas.

Sci Rep 2018 Apr 18;8(1):6173. Epub 2018 Apr 18.

Maimonides Institute of Biomedical Research of Cordoba, Córdoba, 14004, Spain.

Acromegaly is a rare but severe disease, originated in 95% of cases by a growth hormone-secreting adenoma (somatotropinoma) in the pituitary. Magnetic resonance imaging (MRI) is a non-invasive technique used for the diagnosis and prognosis of pituitary tumours. The aim of this study was to determine whether the use of T2-weighted signal intensity at MRI could help to improve the characterisation of somatotropinomas, by analysing its relationship with clinical/molecular features.

Impact of Glucose Metabolism Disorders on IGF-1 Levels in Patients with Acromegaly.

Horm Metab Res 2018 May 11;50(5):408-413. Epub 2018 Apr 11.

Istanbul University, Istanbul Faculty of Medicine, Division of Endocrinology and Metabolism, Istanbul, Turkey.

In this study, we aimed to evaluate the presence of glucose metabolism abnormalities and their impact on IGF-1 levels in patients with acromegaly. Ninety-three patients with acromegaly (n=93; 52 males/41 females) were included in this study. Patients were separated into three groups such as; normal glucose tolerance (n=23, 25%), prediabetes (n=38, 41%), and diabetes mellitus (n=32, 34%). Read More

Predictors of surgical outcome and early criteria of remission in acromegaly.

Endocrine 2018 Jun 6;60(3):415-422. Epub 2018 Apr 6.

Neuroendocrinology Research Center / Endocrinology Division - Medical School and Hospital Universitário Clementino Fraga Filho - Universidade Federal do Rio de Janeiro, Rio de Janeiro, Brazil.

Background: Transsphenoidal surgery (TSS) is the cornerstone of acromegaly treatment, however there are no robust predictors of surgical outcome and remission can only be defined three months after surgery.

Purpose: To analyze if biochemical, demographical, radiological, and immunohistochemical characteristics are predictors of surgical remission and investigate if immediate postoperative GH and IGF-I levels can help defining remission earlier.

Methods: Consecutive acromegaly patients submitted to TSS between 2013-2016 were evaluated. Read More

Craniofacial Manifestations of Systemic Disorders: CT and MR Imaging Findings and Imaging Approach.

Radiographics 2018 May-Jun;38(3):890-911. Epub 2018 Apr 6.

From the Departments of Radiology (V.C.A.A., M.N.C., H.K., A.F., O.S.), Otolaryngology-Head and Neck Surgery (O.S.), and Radiation Oncology (O.S.), Boston University Medical Center, Boston University School of Medicine, 820 Harrison Ave, 3rd Floor, Boston, MA 02118.

Many systemic diseases or conditions can affect the maxillofacial bones; however, they are often overlooked or incidentally found at routine brain or head and neck imaging performed for other reasons. Early identification of some conditions may significantly affect patient care and alter outcomes. Early recognition of nonneoplastic hematologic disorders, such as thalassemia and sickle cell disease, may help initiate earlier treatment and prevent serious complications. Read More

Purpose Understanding of acromegaly disease management is hampered in the US by lack of a national registry. We describe medical management in a population with confirmed acromegaly. Methods Inpatient and outpatient Electronic Health Records (EHR) were used to create a database of de-identified patients assigned the Acromegaly and Gigantism ICD-9 code and/or an appropriate pituitary procedure code at one of four regional hospital systems over a 6-11 year period.
