Growth Hormone-secreting Pituitary Adenoma
A pituitary tumor that secretes GROWTH HORMONE. In humans, excess HUMAN GROWTH HORMONE leads to ACROMEGALY.
A benign tumor, usually found in the anterior lobe of the pituitary gland, whose cells stain with acid dyes. Such pituitary tumors may give rise to excessive secretion of growth hormone, resulting in gigantism or acromegaly. A specific type of acidophil adenoma may give rise to nonpuerperal galactorrhea. (Dorland, 27th ed)
Pituitary Adenylate Cyclase-activating Polypeptide
A multi-function neuropeptide that acts throughout the body by elevating intracellular cyclic AMP level via its interaction with PACAP RECEPTORS. Although first isolated from hypothalamic extracts and named for its action on the pituitary, it is widely distributed in the central and peripheral nervous systems. PACAP is important in the control of endocrine and homeostatic processes, such as secretion of pituitary and gut hormones and food intake.
A collection of NEURONS, tracts of NERVE FIBERS, endocrine tissue, and blood vessels in the HYPOTHALAMUS and the PITUITARY GLAND. This hypothalamo-hypophyseal portal circulation provides the mechanism for hypothalamic neuroendocrine (HYPOTHALAMIC HORMONES) regulation of pituitary function and the release of various PITUITARY HORMONES into the systemic circulation to maintain HOMEOSTASIS.
A condition caused by prolonged exposure to excessive HUMAN GROWTH HORMONE in adults. It is characterized by bony enlargement of the FACE; lower jaw (PROGNATHISM); hands; FEET; HEAD; and THORAX. The most common etiology is a GROWTH HORMONE-SECRETING PITUITARY ADENOMA. (From Joynt, Clinical Neurology, 1992, Ch36, pp79-80)
Arthropathy is an invalidating complication of acromegaly. This arthropathy deteriorates radiographically despite long-term disease control. However, the clinical course and its relationship to the ra...
Double pituitary adenomas are very rare and present up to 1 % of pituitary adenomas in unselected autopsy series and up to 2 % in large surgical series. We report a case of a 47-year-old man present...
We present the first reported case of a craniopharyngioma as a second primary tumor in a patient with acromegaly due to a growth hormone (GH)-secreting pituitary adenoma. The patient was lost for foll...
New criteria that define acromegaly remission are more stringent: normal (age/sex-adjusted) insulin-like growth factor type 1 (IGF-1), growth hormone (GH) random (GHr)
Estrogens have been used in patients with acromegaly since the 1930-1940s, suppressing plasma IGF-1 levels and improving clinical signs and symptoms of acromegaly. Estrogens antagonize GH function at...
Acromegaly is a rare disorder characterized by excessive production of growth hormone most often by a pituitary adenoma. A pituitary adenoma is a tumor, almost always benign or non-cancero...
Acromegaly is a rare, serious condition characterized by chronic hypersecretion of growth hormone (GH), generally caused by a GH-secreting pituitary adenoma. This study will assess the lon...
The purpose of this study is to investigate whether 6 months preoperative treatment with the somatostatin analogue octreotide improves the surgical outcome in patients with acromegaly.
Currently, the first line treatment for acromegaly is surgery, in order to remove the adenoma causing overproduction of growth hormone which leads to acromegaly. Octreotide LAR is approved...
Epidemiological data indicate that patients with active acromegaly have reduced life expectancy because of cardiovascular (60%) and respiratory diseases (25%) mainly (1-10). A post-treatme...
