Octreotide diabetes

Individuals with metabolic dysfunction-associated fatty liver disease (MAFLD) have elevated plasma lipids as well as glucagon, although glucagon suppresses hepatic very low-density lipoprotein-triglyceride (VLDL-TG) secretion. We hypothesize that the sensitivity to glucagon in the hepatic lipid metabolism is impaired in MAFLD. We recruited 11 subjects with severe MAFLD (MAFLD+), 10 with mild MAFLD (MAFLD-), and seven overweight control subjects (CON). We performed a pancreatic clamp with a somatostatin analogue (Octreotide®) to suppress endogenous hormone production, combined with infusion of low-dose glucagon (0...

We describe the multimodal management of a patient with proliferative diabetic retinopathy and diabetic macular edema associated with active acromegaly. A 61-year-old Japanese female who had had type 2 diabetic mellitus for > 10 years complained of deteriorated eyesight. She had distinct acromegalic features, and her visual acuity was 0.05 (right) and 0.4 (left) because of sub-capsular cataracts and proliferative diabetic retinopathy with macular edema. Anti-vascular endothelial growth factor treatments, cataract surgeries and retinal direct laser photocoagulation were performed together with gradual glycemic control with basal insulin to prevent worsening of the visual impairment...

The hypothalamus is the centre of neuroendocrine regulation of energy homeostasis and appetite. Maldevelopment of, or damage to, the key hypothalamic nuclei disrupts the coordinated balance between energy intake and expenditure leading, to rapid and excessive weight gain. Hypothalamic obesity is compounded by a disruption of the hypothalamic-pituitary axis, sleep disruption, visual compromise, and neurological and vascular sequalae. Amongst suprasellar tumors, craniopharyngioma is the most common cause of acquired hypothalamic obesity, either directly or following surgical or radiotherapeutic intervention...

BACKGROUND: Despite biochemically responding to injectable somatostatin receptor ligands (iSRLs), many patients with acromegaly experience treatment burdens. We aimed to assess maintenance of biochemical response and symptomatic control with oral octreotide capsules versus iSRLs in patients with acromegaly who previously tolerated and responded to both. METHODS: This global, open-label, randomised controlled phase 3 trial was done in 29 clinical sites in Austria, France, Germany, Hungary, Italy, Lithuania, Russia, Serbia, Spain, and the USA...

Objective: Non-islet cell tumor hypoglycemia (NICTH) is an uncommon paraneoplastic syndrome associated with mesenchymal neoplasms such as gastrointestinal stromal tumors (GISTs). We report the case of a patient with type 1 diabetes (T1D) and recurrent GIST who not only required discontinuation of insulin therapy but also required continuous parenteral glucose infusions to prevent hypoglycemia. Methods: A 59-year-old woman with a 24-year history of T1D and recurrent GIST presented with frequent episodes of symptomatic hypoglycemia despite continuous reductions in her insulin therapy...

Somatostatin analogues, suchas octreotide and lanreotide, are commonly used in the management of enterocutaneous fistula. We report a case of severe and prolonged hyperglycemia that occurred in a patient after receiving a one-time dose of lanreotide, who had previously been stable on octreotide and did not have a history of diabetes mellitus. Management of the patient's hyperglycemia while receiving parenteral nutrition is described.

A 67-year-old female presented with severe hypoglycemia with a blood glucose of 34 mg/dl five hours after having dinner. She did not have diabetes and had no access to oral hypoglycemic agents, insulin, or any other drug known to cause hypoglycemia. She was a known case of primary hypothyroidism euthyroid on treatment. The physical examination was unremarkable. Her liver, renal functions, thyroid, and adrenal functions were normal. At a blood sugar level of 23 mg/dl, her serum insulin was 24,000 uU/ml (normal: <3 uU/ml) and C-peptide was 16...

Acromegaly is a rare disorder of unregulated hypersecretion of growth hormone that causes cardiovascular, metabolic and respiratory complications. Herein, we describe the case of a middle-aged man admitted to the hospital with severe COVID-19 found to have clinical and biochemical evidence of acromegaly. His respiratory status declined despite initiation of standard treatments, prompting initiation of subcutaneous octreotide. Following initiation of this therapy, he rapidly improved and was discharged from the hospital 2 days later...

BACKGROUND: The long-acting somatostatin analog lanreotide autogel is effective in the treatment of patients with neuroendocrine tumors. OBJECTIVE: To evaluate the long-term treatment response in patients with neuroendocrine tumors receiving lanreotide autogel in routine clinical practice. METHODS: Non-interventional, 24-month study in patients with neuroendocrine tumors treated with lanreotide autogel (NCT01840449). RESULTS: Patients (n=80) from 26 centers in Germany and Austria were enrolled...

Summary: Acromegaly is a rare, chronic progressive disorder with characteristic clinical features caused by persistent hypersecretion of growth hormone (GH), mostly from a pituitary adenoma (95%). Occasionally, ectopic production of GH or growth hormone-releasing hormone (GHRH) with resultant GH hypersecretion may lead to acromegaly. Sometimes localizing the source of GH hypersecretion may prove difficult. Rarely, acromegaly has been found in patients with an empty sella (ES) secondary to prior pituitary radiation and/or surgery...

Summary: Oncogenic osteomalacia secondary to glomus tumor is extremely rare. Localization of causative tumors is critical as surgical resection can lead to a complete biochemical and clinical cure. We present a case of oncogenic osteomalacia treated with resection of glomus tumor. A 39-year-old woman with a history of chronic sinusitis presented with chronic body ache and muscle weakness. Biochemical evaluation revealed elevated alkaline phosphatase hypophosphatemia, increased urinary phosphate excretion, low calcitriol, and FGF23 was unsuppressed suggestive of oncogenic osteomalacia...

INTRODUCTION: The FDA approval of oral semaglutide for type 2 diabetes (2019) and oral octreotide for acromegaly (2020) is evidence that selected niche peptides can be administered orally if formulated with selected intestinal permeation enhancers. AREAS COVERED: We evaluated the oral octreotide formulation, MYCAPSSA® (Chiasma Pharmaceuticals, Needham, MA, USA). An outline of the current standard of care in acromegaly and the benefits of oral octreotide versus depot injections is provided...

BACKGROUND: Pasireotide long acting (LAR) can be effective in normalizing insulin-like growth factor (IGF)-1 level in acromegaly patients inadequately controlled by octreotide or lanreotide. OBJECTIVE: Determine the long-term efficacy and safety of pasireotide, including time to biochemical control and time to best response, and risk for diabetes mellitus. METHODS: A retrospective multicenter study investigating the efficacy and safety of pasireotide LAR treatment in patients with active acromegaly treated for >12 months...

Medications used to treat diabetes mellitus are heterogeneous, with widely differing safety profiles in therapeutic use and in overdose. Insulin overdose may produce severe and prolonged hypoglycemia. Sulfonylurea poisoning should be treated with octreotide, sparing intravenous dextrose where possible. Acute metformin overdose may lead to life-threatening acidosis with elevated lactate concentrations, which may require hemodialysis. Glucagon-like peptide 1 agonists and dipeptidyl peptidase 4 inhibitors are benign in overdose in diabetic patients but may produce profound hypoglycemia in nondiabetic patients...

SUMMARY: A 38-year-old female was identified as carrying a heterozygous pathogenic MEN1 variant (c.1304delG) through predictive genetic testing, following a diagnosis of familial hyperparathyroidism. Routine screening for parathyroid and pituitary disease was negative. However, cross-sectional imaging by CT revealed a 41 mm pancreatic tail mass. Biopsy via endoscopic ultrasound confirmed the lesion to be a well-differentiated (grade 1) pancreatic neuroendocrine tumour (pNET) with MIB1<1%...

SUMMARY: A 50-year-old woman with thyroid-stimulating hormone (TSH)-producing pituitary adenoma (TSHoma) was diagnosed due to symptoms of thyrotoxicosis. Preoperatively, she showed thyrotoxicosis with the syndrome of inappropriate secretion of TSH (SITSH) and had a 5 cm nodule in her thyroid gland. Octreotide was administered preoperatively, which helped lower her serum TSH level but not her thyroid hormone level. These findings were atypical for a patient with TSHoma. The TSHoma was completely resected, and the TSH level dropped below the sensitivity limit shortly after surgery...

INTRODUCTION: Increasing arterial stiffness is a feature of vascular aging that is accelerated by conditions that enhance cardiovascular risk, including diabetes mellitus. Multiple studies demonstrate divergence of carotid-femoral pulse wave velocity and augmentation index in persons with diabetes mellitus, though mechanisms responsible for this are unclear. MATERIALS AND METHODS: We tested the effect of acutely and independently increasing plasma glucose, plasma insulin, or both on hemodynamic function and markers of arterial stiffness (including carotid-femoral pulse wave velocity, augmentation index, forward and backward wave reflection amplitude, and wave reflection magnitude) in a four-arm, randomized study of healthy young adults...

SUMMARY: Ectopic adrenocorticotropic hormone (ACTH) secretion is responsible for 5-15% of Cushing's syndrome (CS). Neuroendocrine tumor (NET) is a common cause of ectopic ACTH syndrome (EAS). However, primary renal NET is exceedingly rare. Fewer than 100 cases have been reported and only a few cases presented with CS. Because of its rarity and lack of long-term follow-up data, clinical manifestations, biological behavior and prognosis are not well understood. Here, we report the case of a 51-year-old man who presented with clinical and laboratory findings compatible with EAS...

Congenital hyperinsulinism (CHI) characterised by inappropriate secretion of insulin despite low blood glucose can result in irreversible brain damage if not promptly treated. The most common genetic cause of hyperinsulinism is the pathogenic variants in ABCC8 and KCNJ11 , causing dysregulated insulin secretion. Rapid testing is crucial for all patients because finding a mutation significantly impacts this condition's clinical management. We report a rare case of focal CHI after a homozygous KCNJ11 mutation who underwent a selective lesionectomy and required octreotide for euglycaemia...
