BACKGROUND Octreotide long-acting repeatable (LAR) is approved in the United States for the management of carcinoid syndromes among patients with neuroendocrine tumors (NET). The objective of our study is to evaluate the impact of octreotide LAR on overall survival (OS), as it has not been established. METHODS NET patients of 65 years and older diagnosed between January 1999 and December 2009...

The use of octreotide-LAR and cabergoline therapy has shown great promise in adults with acromegaly; however, the experience in pediatric patients has rarely been reported. We described a clinical course of a 15-year-old boy of McCune-Albright syndrome (MAS) with pituitary gigantism. At the age of 8 years, a growth hormone (GH) and prolactin (PRL) producing pituitary adenoma was diagnosed at ou...

IMPORTANCE Chyle fistula is an uncommon complication of neck surgery. A variety of management strategies have been described, including diet restriction, parenteral nutrition, use of pressure dressings, and revision surgery. Octreotide has been used with success in patients with neck and thoracic chyle fistulas, but data regarding efficacy in neck chyle fistulas are lacking. OBJECTIVE To eval...

The objective of this study was to investigate the impact of different hydrophobic ion pairs (HIP) on the oral bioavailability of the model drug octreotide in pigs. Octreotide was ion paired with the anionic surfactants deoxycholate, decanoate and docusate differing in lipophilicity. These hydrophobic ion pairs were incorporated in self-emulsifying drug delivery systems (SEDDS) based on BrijO10...

The mammalian target of rapamycin (mTOR) signaling pathway has emerged as a promising target for cancer therapy. Rapamycin inhibits mTOR activity but induces upstream signaling, leading to Akt activation, potentially limiting antitumor activity. Octreotide, a somatostatin analog, decreases phosphatidylinositol-3-kinase/Akt signaling in some models, and thus theoretically may enhance rapamycin's...

Background—Few studies have compared vasoactive drugs with endoscopic sclerotherapy in the control of acute variceal haemorrhage. Octreotide is widely used for this purpose, but its value remains undetermined. Aims—To compare octreotide with endoscopic sclerotherapy for acute variceal haemorrhage. Patients—Consecutive patients with acute variceal haemorrhage. Methods—Patients were randomised at...

BACKGROUND AND OBJECTIVES Surgery in carcinoid patients can provoke a carcinoid crisis, which can have serious sequelae, including death. Octreotide prophylaxis is recommended to prevent carcinoid crisis, however there are few reports of outcomes and no large series examining its efficacy. We hypothesized that a 500 µg prophylactic octreotide dose is sufficient to prevent carcinoid crisis. ME...

BACKGROUND Acromegalic patients have slow colonic transit, increased rates of deoxycholic acid formation, and an increased prevalence of cholesterol gall stones, especially during long term octreotide treatment. However, the effects of this prolonged large bowel transit time on the numbers of faecal anaerobes and the activities of the enzyme systems which biotransform conjugated cholic acid int...

The plasma concentration and biliary excretion profiles of a cationic cyclic octapeptide, octreotide, were compared between control rats and rats given an intravenous infusion of a bile acid, taurocholate (TCA), and an organic anion, dibromosulfophthalein (DBSP). Both TCA and DBSP reduced the plasma elimination and biliary excretion of octreotide after its intravenous bolus administration. Two ...

Hepatic stellate cells (HSCs) are important in the development of liver fibrosis and in the pathogenesis of portal hypertension. Octreotide, an analogue of somatostatin, has been demonstrated to effectively treat fibrosis and portal hypertension; however, its relative mechanism in HSCs remains unknown. LX‑2, the immortalized HSC line, was used to study the mechanism whereby octreotide functions...
