Filter by:Sleep apnea is a common situation that affects up to 80% of acromegalic patients. This disease is linked to disturbance on the carbohydrate metabolism increasing the rates of diabetes. The objective of this trial is to assess (with the euglycemic hyperinsulinemic clamp) the impact of the treatment of sleep apnea, with a continuous positive air pressure device (CPAP), on the insulin resistance.
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.
This study will evaluate the efficacy and safety of pasireotide LAR 40 and 60 mg versus octreotide LAR or lanreotide ATG in patients with inadequately controlled acromegaly.
Check the pharmacodynamics of the drug octreotide acetate LAR 30 mg imported and distributed by Chemical Laboratory Pharmaceutical Bergamo Ltda. compared to the drug Sandostatin LAR ® (octreotide acetate 30 mg) manufactured by Novartis Biociências S / A, using as activity analysis of growth hormone (GH) and growth factor insulin-like 1 (IGF-1 ) after a single dose of the drug in patients with acromegaly
The aim of this study is to investigate peripheral effects of Somatostatin on glucose metabolism and growth hormone (GH) signalling in healthy men. Eight subjects will be enrolled. The hypothesis is that Somatostatin infusion reverses insulin resistance caused by GH.
The aim of the study is to evaluate the interest of a six month pre-operative treatment with a long-acting somatostatin analog (Sandostatin LP) versus surgery alone in patients with a pituitary adenoma responsible for acromegaly.
In acromegaly, nearly 40% of patients fail to control GH/IGF-I levels with somatostatin analogues (SA). Dopaminergic agonists (DA) are even less effective, but combination therapy with SA and DA normalizes IGF-I levels in 33-56% of patients in short-term studies. This study was designed to evaluate short and long term efficacy of cabergoline in controlling IGF-I levels in acromegalic patients receiving octreotide.
Evaluate biochemical differences in acromegalic patients treated with surgery versus somatostatin analogues (SMS) (after surgery or alone). Hypothesis: Treatment modality exhibit different biochemical responses in acromegaly.
The purpose of this study is to assess the efficacy of repeated subcutaneous (under the skin) injections at different doses of BIM 23A760 on growth hormone and insulin-like growth factor-1 levels in patients with acromegaly after 6 months of treatment.
Previous studies addressing preoperative somatostatin analogs (SSA) treatment and subsequent surgical cure rates are conflicting, reporting a benefit, or no difference between groups. And most reported studies were rather small and were made in retrospect, we conducted a prospective, randomized study to investigate whether 4-month preoperative lanreotide treatment would improve the surgical cure rate of newly diagnosed acromegalic patients with macroadenomas. The investigators also aimed to investigate whether there were differences in the incidence of surgical complications, and duration of neurosurgical hospital stay.
