Metabolic Complications of Acromegaly.

Metabolic Complications of Acromegaly. Front Horm Res. 2018;49:20-28 Authors: Mercado M, Ramírez-Rentería C Abstract 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. The lipolytic effect of GH results in the mobilization of free fatty acids that further contributes to the decreased insulin sensitivity found in these patients. Some studies suggest that the presence of diabetes contributes to the increased mortality of acromegaly, although this remains controversial. Successful treatment of acromegaly usually results in significant, albeit incomplete improvements of the abnormal metabolic profile. PMID: 29895013 [PubMed - in process]

Publication date: March–April 2019Source: Diabetes &Metabolic Syndrome: Clinical Research &Reviews, Volume 13, Issue 2Author(s): Leila Moradi, Fatemeh Amiri, Hajieh ShahbazianAbstractPatients with acromegaly have soft tissue overgrowth that induced characteristic clinical presentation. A growth hormone-secreting adenoma of the anterior pituitary gland is the most common cause of acromegaly. Metabolic and somatic features of acromegaly caused by high serum concentrations of insulin-like growth factor-I (IGF-I) and excess growth hormone (GH) production. we present a case of ‘pseudoacromegaly’ with a...

We present a case series of 17 pregnancies in 12 women with acromegaly. 12 women with acromegaly who completed pregnancy were identified from centres involved in the Irish Pituitary Study. 11 women had pituitary macroadenomas, one woman had a microadenoma. Only 5/17 pregnancies had optimal biochemical control of acromegaly pre-conception, as defined by IGF-1 concentration in the age related reference level and plasma GH concentration of

AbstractPurposeThe surgical outcome on glucose metabolism in acromegaly patients is not fully understood. We aimed to investigate the impact of surgery on glucose metabolism and identify key factors that influence alterations of glucose metabolic status in acromegaly patients.MethodsOral glucose tolerance test was performed in 151 newly diagnosed acromegaly patients before and 3 –12 months after surgery. Insulin resistance and insulin secretion was assessed. Patients were grouped as cured, discordant, and having active disease according to postoperative growth hormone (GH) and insulin-like growth factor-1 (IGF-1) lev...

Purpose of review Elevated circulating levels of growth hormone (GH) and/or increased expression of the GH receptor in the kidney are associated with the development of nephropathy in type1 diabetes and acromegaly. Conditions of GH excess are characterized by hyperfiltration, glomerular hypertrophy, glomerulosclerosis and albuminuria, whereas states of decreased GH secretion or action are protected against glomerulopathy. The direct role of GH's action on glomerular cells, particularly podocytes, has been the focus of recent studies. In this review, the emerging role of GH on the biological function of podocytes and its ...

Abstract Carney complex is a rare, autosomal dominant, multiple endocrine neoplasia and lentiginosis syndrome, caused in most patients by defects in the PRKAR1A gene, which encodes the regulatory subunit type 1α of protein kinase A. Inactivating defects of PRKAR1A lead to aberrant cyclic-AMP-protein kinase A signaling. Patients may develop multiple skin abnormalities and a variety of endocrine and non-endocrine tumors. Endocrine manifestations include primary pigmented nodular adrenocortical disease, that may cause Cushing syndrome, growth-hormone secreting pituitary adenoma or pituitary somatotropic hyperpl...
