Active clinical trials for "Congenital Hyperinsulinism"

This will be a prospective single-arm before-and-after clinical trial in which raw corn starch (RCS) will be first applied on patients with unoperated insulinoma. Nutritional intervention with supplementation of RCS will be initiated in 20 patients with suspected insulinoma to improve their hypoglycemia before the surgery. Duration of nutritional intervention, fasting blood glucose, lipid profile, weight change, BMI and other metabolic indices will be recorded and compared before and after the intervention.

Roux-en-Y gastric bypass (RYGB) is the most common surgical procedure for morbid obesity. However, it can present serious late complications, like postprandial hyperinsulinemic hypoglycemia (PHH). Recent data suggested an increase in intestinal SGLT1 after RYGB. However, there are no data on the inhibition of SLGT1 to prevent PHH in patients with prior RYBG. Objectives: To evaluate in patients that present PHH after RYGB: a) the effect of canagliflozin 300mg on the response to 100g glucose overload (OGTT); b) the pancreatic response after intra-arterial calcium stimulation. Material and methods: Prospective pilot study, including patients with PHH after RYGB, matched by age and gender with healthy controls. Basal OGTT and after 2-weeks of daily 300mg of canagliflozin will be performed. In addition, venous sampling after intra-arterial calcium stimulation of the pancreas will be performed.

The purpose of our study is to evaluate the efficacy and safety of Lanreotide Autogel in children with congenital hyperinsulinism already treated with Octreotide by pump. Congenital hyperinsulinism is a genetic disorder characterized by inappropriate insulin secretion resulting in persistent hypoglycemia (low blood sugars. Patients exposed to recurrent hypoglycemic episodes are at increased risk of developmental disorders, so identification and prompt management of patients are essential. Many patients are treated with the somatostatin analog Octreotide which is administered by continuous infusion using a pump (we use an insulin pump). This treatment may pose a huge burden and be stressful for patients and families as it demands intensive daily care. In an effort to simplify the daily care of our patients and improve their quality of life we will study the efficacy and safety of Lanreotide Autogel - a long-acting somatostatin analog that can be administered by injection once a month

To analyze and evaluate the efficacy and safety of octreotide subcutaneous injection in the treatment of diazazine-ineffective congenital hyperinsulinemia (CHI) in children.

Post-gastric bypass hyperinsulinemic hypoglycemia is a recently described disorder occurring in some patients after gastric bypass surgery for obesity. The pathogenesis is incompletely understood but involves a robust insulin response to ingested carbohydrate. The resultant hyperinsulinemia sometimes produces hypoglycemia with neuroglycopenia, confusion and even loss of consciousness. Various treatments have been recommended including low carbohydrate diets, coingestion of the medication acarbose with carbohydrate containing meals, partial pancreatectomy and even total pancreatectomy. None is completely satisfactory. We propose to test two new potential treatments. Using a design with random assignment of three conditions we plan to compare, in 10 patients with post-gastric bypass hyperinsulinemic hypoglycemia, a high carbohydrate test meal (control condition), a high carbohydrate test meal after pre-treatment with rapid acting aspart insulin (insulin condition), and a high fructose, low glucose test meal with carbohydrate and caloric content similar to the control meal (fructose condition).

The primary objective of this study is to assess the neuro-endocrine response to hypoglycaemia in PHH vs. non-PHH post-gastric bypass individuals.

This is an open-label positron emission tomography/computed tomography (PET/CT) study to investigate the diagnostic performance and evaluation efficacy of 68Ga-NOTA-exendin-4 in insulinoma and nesidioblastosis patients. A single dose of 55.5-111 Mega-Becquerel (MBq) 68Ga-NOTA-exendin-4 will be injected intravenously. Visual and semiquantitative method will be used to assess the PET/CT images.

Congenital hyperinsulinism is a rare condition that can cause life-threatening hypoglycemia. Current treatment for congenital hyperinsulinism is often suboptimal, and such individuals may respond to a new somatostatin analog, pasireotide. This is a compassionate use study of the effects of pasireotide on individuals with suboptimally treated congenital hyperinsulinism.

Observational study in patients with non-focal congenital hyperinsulinism showing that restrictive surgery may improve the metabolic situation

The primary objective of this study is to evaluate the utility of [18F]-DOPA PET to provide improved presurgical planning and distinguish between focal and diffuse forms of HI. The investigators will perform descriptive analysis, relying on visual analysis to diagnose and localize a focal lesion. Our findings will be compared to surgical histopathology to determine sensitivity and specificity or this technique. The investigators will also track patient surgical outcomes, specifically whether the patient is surgically "cured" or still requires medical management to control residual hypoglycemia.
