Octreotide diabetes

Murray B Gordon, Kellie L Spiller
Long-acting pasireotide is an effective treatment option for acromegaly, but it is associated with hyperglycemia, which could impact its use in patients with diabetes. We present a case of a 53-year-old man with acromegaly and type 2 diabetes mellitus (glycated hemoglobin (HbA1c): 7.5%), who refused surgery to remove a pituitary macroadenoma and enrolled in a Phase 3 clinical trial comparing long-acting pasireotide and long-acting octreotide in acromegalic patients. The patient initially received octreotide, but insulin-like growth factor 1 (IGF-1) levels remained elevated after 12 months (383...

The purpose of the present study is to investigate the possible healing effects of octreotide (OCT) on motor performance, electrophysiological and histopathological findings of diabetic neuropathy in a rat model of diabetes mellitus (DM). To induce diabetes, rats were administered a single dose (60mg/kg) of streptozotocin (STZ). Diabetic rats were treated either with saline (1ml/kg/day, n=7) or OCT (0.1mg/kg/day, n=7) for four weeks. Seven rats served as control group and received no treatment. At the end of the study, electromyography (EMG), gross motor function (inclined plate test), general histology and the perineural thickness of sciatic nerve were evaluated...

BACKGROUND: Hypoglycemia occurs frequently in patients both in the inpatient and outpatient settings. While most hypoglycemia unrelated to diabetes treatment results from excessive endogenous insulin action, rare cases involve functional and congenital mutations in glycolytic enzymes of insulin regulation. CASE: A 21-year-old obese woman presented to the emergency department with complaints of repeated episodes of lethargy, syncope, dizziness, and sweating. She was referred from an outside facility on suspicion of insulinoma, with severe hypoglycemia unresponsive to repeated dextrose infusions...

Peptides are receiving increasing interest as clinical therapeutics. These highly tunable molecules can be tailored to achieve desirable biocompatibility and biodegradability with simultaneously selective and potent therapeutic effects. Despite challenges regarding up-scaling and licensing of peptide products, their vast clinical potential is reflected in the 60 plus peptide-based therapeutics already on the market, and the further 500 derivatives currently in developmental stages. Peptides are proving effective for a multitude of disease states including: type 2 diabetes (controlled using the licensed glucagon-like peptide-1 receptor liraglutide); irritable bowel syndrome managed with linaclotide (currently at approval stages); acromegaly (treated with octapeptide somatostatin analogues lanreotide and octreotide); selective or broad spectrum microbicidal agents such as the Gram-positive selective PTP-7 and antifungal heliomicin; anticancer agents including goserelin used as either adjuvant or monotherapy for prostate and breast cancer, and the first marketed peptide derived vaccine against prostate cancer, sipuleucel-T...

PURPOSE: Growing evidence indicates neuroprotection as a therapeutic target in diabetic retinopathy (DR). We tested the hypothesis that VEGF is released and acts as a survival factor in the retina in early DR. METHODS: Ex vivo mouse retinal explants were exposed to stressors similar to those characterizing DR, that is, high glucose (HG), oxidative stress (OS), or advanced glycation end-products (AGE). Neuroprotection was provided using octreotide (OCT), a somatostatin analog, and pituitary adenylate cyclase activating peptide (PACAP), two well-documented neuroprotectants...

Morbidity and mortality rates in patients with active acromegaly are higher than the general population. Adequate biochemical control restores mortality to normal rates. Now, medical therapy has an increasingly important role in the treatment of patients with acromegaly. Somatostatin receptor ligands (SRLs) are considered the standard medical therapy, either after surgery or as a first-line therapy when surgery is deemed ineffective or is contraindicated. Overall, octreotide and lanreotide are first-generation SRLs and are effective in ~20%-70% of patients...

BACKGROUND: Acromegaly is a chronic disorder characterized by excess growth hormone secretion and elevated insulin-like growth factor-1 levels most often caused by a pituitary adenoma. Clinical presentation of the disease includes coarsening of the facial features, soft-tissue swelling of the hands and feet, and overgrowth of the frontal skull and protrusion of the jaw, as well as joint symptoms. Acromegaly is associated with several comorbidities, including diabetes, cardiovascular disease, and arthropathy, which, if left untreated, can lead to early mortality...

Fasting blood glucose (FBG) and hepatic glucose production are regulated according to a circadian rhythm. An early morning increase in FBG levels, which is pronounced among diabetic patients, is known as the dawn phenomenon. Although the intracellular circadian clock generates various molecular rhythms, whether the hepatic clock is involved in FBG rhythm remains unclear. To address this issue, we investigated the effects of phase shift and disruption of the hepatic clock on the FBG rhythm. In both C57BL/6J and diabetic ob/ob mice, FBG exhibited significant daily rhythms with a peak at the beginning of the dark phase...

HYPOTHESIS: The growth hormone (GH) excess displayed in acromegaly induces insulin resistance up to diabetes mellitus (DM). The somatostatin analogues (as octreotide LAR) are useful in controlling the GH levels but disturbances of glucose metabolism might be seen. OBJECTIVE: This study evaluates the acromegalic glycemic profile under octreotide. METHODS & RESULTS: Out of the total number of patients (N=34) diagnosed with active acromegaly, only some were followed (N=25; male/ female ratio: 6/ 19; mean age: 51...
