BACKGROUND The effect and possible timing of nonradiolabeled somatostatin analogue octreotide are still not determined in the treatment of medulloblastoma, while the presence of somatostatin receptor type-2 (SSTR2) is proved in the majority of medulloblastoma by several authors. PROCEDURES Daoy, SSTR2A positive medulloblastoma cell culture was tested with octreotide in monotherapy and combine...

Peptide hormone somatostatin and its receptors have a wide range of physiological functions and play a role in the treatment of numerous human diseases, including colorectal cancer. Octreotide, a synthetic somatostatin-analog peptide, inhibits growth of colonic cancer cells primarily by binding to G-protein coupled receptors and elicits cellular responses through second-messenger systems. Insul...

Objective: Octreotide is used to treat patients with neuroendocrine tumors. Previous reports show that octreotide long-acting repeatable (LAR) dose and patient body weight affect nadir plasma octreotide levels (approximately 1250, 2500, 5000, and 11,000 pg/mL for LAR doses of 10, 20, 30 and 60 mg/mo). However, plasma octreotide levels have decreased over time in patients receiving these doses o...

CONTEXT Congenital hyperinsulinism (HI) is a common cause of hypoglycemia in infancy. The medical treatment of diazoxide-unresponsive HI is based on a somatostatin analogue. OBJECTIVE This study aims at replacing three daily s.c. octreotide (Sandostatin, Novartis) injections by a single and monthly i.m. injection of long-acting release (LAR) octreotide (Sandostatin LP, Novartis) in HI patient...

INTRODUCTION The safety of octreotide use, in its short-acting preparation, in pregnancy is still unclear. This report provides the first documentation of uneventful octreotide LAR use during three pregnancies in a woman with bronchial carcinoid-associated adrenocorticotropic hormone-dependent Cushing's syndrome. CASE PRESENTATION A 25-year-old Arabic woman presented to our emergency departme...

In human somatotroph adenomas, growth hormone (GH) hypersecretion can be inhibited by somatostatin analogues such as octreotide. Unfortunately, serum GH levels reach normal values in only 60% of treated patients. The decreased sensitivity to octreotide is strongly related to a lower expression of somatostatin receptor sst2. In this present study, the sst2 gene was transferred by an adenoviral v...

The effects of octreotide on six normal subjects and five patients with scleroderma were investigated. Changes in intestinal motility and in plasma motilin were examined after a single injection of octreotide. Octreotide stimulated intense intestinal motor activity in normal subjects. Motility patterns in the scleroderma patients were chaotic and non-propagative, but, after octreotide was given...

The patient with a history of bone pain and muscle weakness, was thought to have oncogenic osteomalacia as a result of biochemical investigations and directed to Nuclear Medicine Department for a whole-body bone scintigraphy and 111In-octreotide scintigraphy. There was no focal pathologic tracer uptake, but generalized marked increase in skeletal uptake on bone scintigraphy. Octreotide scintigr...

domized trials (2,245 patients) showed a significant reduction in overall postoperative complications by 31% and a reduced fistula rate in the octreotide group. This systematic review consequently recommended preventive octreotide application for routine use in patients undergoing pancreatic resections [9] . On the other hand, Gans et al. [10] showed in their meta-analysis published in the Brit...

1. In autonomic failure, supine exercise lowers blood pressure and worsens postural hypotension. The somatostatin analogue, octreotide, reduces post-prandial and postural hypotension, but its effects on exercise-induced hypotension and on postural hypotension post-exercise are unknown. 2. Eighteen subjects with chronic sympathetic denervation were studied; 12 had pure autonomic failure and six ...
