pegylation is a well-established technique utilized to overcome the problems related to the therapeutic applications of peptides and proteins. reasons for the pegylation of these biological macromolecules include reducing immunogenicity, proteolytic degradation and rapid clearance from blood circulation. octreotide is an octapeptide analogue of naturally-occurred somatostatin. this peptide has ...

The neurosurgical literature contains little information about the current management of patients with thyroid-stimulating hormone (TSH)-secreting pituitary adenomas or about the usefulness of the somatostatin analogue octreotide in such cases. While TSH-secreting pituitary adenomas are rare, our review and illustrative case demonstrate the effectiveness of pretreating patients with octreotide ...

BACKGROUND Effects of octreotide on post-endoscopic retrograde cholangiopancreatography pancreatitis have been studied in many clinical trials. These trials have yielded inconclusive results. Results of more recent studies using larger doses, however, seem to be more optimistic. AIM To examine effects of octreotide at different doses on PEP. METHODS A comprehensive search of relevant databa...

BACKGROUND Prospective randomized trials indicate that prophylactic octreotide treatment does not decrease the incidence of postoperative pancreatic fistula (POPF). The aim of this study was to analyze if octreotide prophylaxis could decrease the severity grade of POPFs after pancreatic surgery. METHOD Seventy-eight of 684 patients undergoing pancreatic resection with POPF were included in th...

Somatostatin receptors (SSTR) are highly expressed in well-differentiated neuroendocrine tumors (NET). Octreotide, an SSTR agonist, has been used to suppress the production of vasoactive hormones and relieve symptoms of hormone hypersecretion with functional NETs. In a clinical trial, an empiric dose of octreotide treatment prolonged time to tumor progression in patients with small bowel neuroe...

1. Portal hypertension and hyperdynamic circulation have been postulated to play a role in the pathogenesis of portal hypertensive gastropathy. Administration of octreotide to portal hypertensive rats has been shown to reduce portal pressure and ameliorate hyperdynamic circulation. 2. This study investigated the effects of chronic administration of octreotide on systemic and portal haemodynamic...

BACKGROUND Effective, non-invasive, palliative strategies for symptomatic malignant ascites are unavailable. This trial explored whether octreotide, an inhibitor of vascular endothelial growth factor, a putative mediator of ascites, prolongs the interval to next paracentesis. METHODS After a baseline paracentesis and a test of short-acting agent, patients with symptomatic ascites were randoml...

OBJECTIVE To evaluate the endpoints of complications (specifically pancreatic fistula and total complications) and death in patients undergoing pancreaticoduodenectomy. SUMMARY BACKGROUND DATA Four randomized, placebo-controlled, multicenter trials from Europe have evaluated prophylactic octreotide (the long-acting synthetic analog of native somatostatin) in patients undergoing pancreatic res...

BACKGROUND Gastrointestinal (GI) bleeding is one of the most common complications after continuous-flow left ventricular assist device implantation. More than one third of patients with incident bleed go on to develop recurrent GI bleeding. Octreotide, a somatostatin analog, is proposed to reduce the risk of recurrent GI bleeding in this population. METHODS AND RESULTS This multicenter, retro...

A 75-year-old male patient with non-avid radioiodine Hurthle cell carcinoma was evaluated by 99m Tc- octreotide scintigraphy, in order to find possible metastatic lesions. A bony metastatic lesion was detected by this procedure which was confirmed by histopathology.99mTc-octreotide scintigraphy is a precise and cost-effective imaging modality for detection of non-iodine av...
