Acromegaly is a disease of the pituitary gland that involves the overproduction of growth hormone. The drug works by blocking the binding of growth hormone to growth hormone receptors found in tissues throughout the body. Human studies have evaluated the reduction of IGF-I levels in the blood following pegvisomant treatment, however, no studies have evaluated IGF-I levels in tissues following pegvisomant administration. In this study, we will test a novel tissue biomarker for pegvisomant action, distinct from measuring IGF-I levels in the blood. To this end, we will determine if administration of pegvisomant modifies the expression of IGF-I, IGF-I receptor, growth hormone receptor and GH- and IGF-i-dependent signaling molecules in the colon tissue of patients with acromegaly.

The purpose of the study is to determine if Pegvisomant is more efficacious than Sandostatin LAR Depot in normalizing IGF-I levels in treatment naive patients with acromegaly.
Primary objective: To investigate the efficacy and safety of Pegvisomant in Japanese patients with acromegaly.
In this study the investigators will evaluate whether combination low dose somatostatin receptor ligand (SRL) and weekly or daily Pegvisomant will attain equivalent control of serum IGF-1 ...
The objective of this study is to assess the efficacy of Pasireotide LAR alone and in combination with weekly Pegvisomant in acromegaIy patients previously controlled with combination trea...
The purpose of the study is to investigate the efficacy of an acute additional application of the somatostatin analogue octreotide 100µg s.c. or the dopamine agonist cabergoline 0.5mg p.o...
Acromegaly has been associated with increased risk of cancer morbidity and mortality, but research findings remain conflicting and population-based data are scarce. We therefore examined whether patie...
Provocative stimulation tests for growth hormone (GH) assessment have poor reproducibility and can often elicit false positive results in normal children. The aim of our study was to confirm the capab...
Acromegaly increases the risk of cardiovascular mortality. Data on the cardiovascular risk in asymptomatic acromegaly are limited. In particular, data on coronary microvascular abnormalities are lacki...
Sex and age are factors conferring resistance to medical treatment in patients with acromegaly. However, their impact on outcomes of transsphenoidal adenomectomy (TSA) has not been evaluated.
Diabetes and hypertension are frequent comorbidities of acromegaly.
The presence of an excessively large tongue, which may be congenital or may develop as a result of a tumor or edema due to obstruction of lymphatic vessels, or it may occur in association with hyperpituitarism or acromegaly. It also may be associated with malocclusion because of pressure of the tongue on the teeth. (From Jablonski, Dictionary of Dentistry, 1992)
A pituitary tumor that secretes GROWTH HORMONE. In humans, excess HUMAN GROWTH HORMONE leads to ACROMEGALY.
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)
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)
A disorder characterized by recurrent apneas during sleep despite persistent respiratory efforts. It is due to upper airway obstruction. The respiratory pauses may induce HYPERCAPNIA or HYPOXIA. Cardiac arrhythmias and elevation of systemic and pulmonary arterial pressures may occur. Frequent partial arousals occur throughout sleep, resulting in relative SLEEP DEPRIVATION and daytime tiredness. Associated conditions include OBESITY; ACROMEGALY; MYXEDEMA; micrognathia; MYOTONIC DYSTROPHY; adenotonsilar dystrophy; and NEUROMUSCULAR DISEASES. (From Adams et al., Principles of Neurology, 6th ed, p395)
