Filter by:This study investigated any potential associations between two isocaloric diets with different meal frequency (3 meals versus 6 meals) and glycemic control in people at high diabetes risk (lean and overweight/obese women with PCOS, individuals with hyperinsulinemia, individuals with impaired glucose tolerance) and diagnosed with diabetes.
The purpose of this study is to learn more about how U500 regular insulin can be effectively be used to treat type 2 diabetes. Most insulin treated patients with type 2 diabetes take U100 insulin, but if they require large doses (such as >150 units a day) they may experience pain at this site of injection and the absorption of the insulin is unpredictable, thereby leading to poor glucose control. To overcome these problems, doctors sometimes switch to a more concentrated form of insulin called U500 insulin. U500 is five times as concentrated as U100 insulin and therefore delivers an equivalent dose of insulin in much lesser volume. However, how to best use U-500 insulin is not certain. The investigators are not really sure how long a given dose is effective in patients who require large doses (>150 units of U100 insulin), so are not sure of how often the drug should be administered. In this study, the investigators will determine how effective two different doses of U-500 regular insulin (100 U and 200 U) are in lowering blood sugar and how long these two doses last. This information will help doctors develop better treatment plans for patients with type 2 diabetes.
Observational study in patients with non-focal congenital hyperinsulinism showing that restrictive surgery may improve the metabolic situation
Children with congenital hyperinsulinism (CHI) have low blood sugar, and some of these children may require surgery to remove part or all of their pancreas. In this study, researchers will test how well a radioactive drug, 18-labeled L-fluorodeoxyphenylalanine (called F-DOPA) can detect a form of hyperinsulinism (focal HI) that may be cured by surgery. Eligible participants in this study will have positron emission tomography/computerized tomography (PET/CT) scans with F-DOPA prior to surgery.
tPA has a pivotal role in placentation, mediationg activation of growth factors, such as vascular endothelial growth factor and brain-derived neurotrophic factor, degradation of extracellular matrix and basement membrane (directly or through activation of matrix metalloproteinases) and formation of hemidesmosomes. A high-carbohydrate intake combined with lack of physical activity provides a strong stimulus for maternal insulin production. In this scenario, either β-cells are dysfunctional and diabetes supervenes, or excessive amounts of insulin are produced, providing pathological stimulation of PAI-1 synthesis. Given that PAI-1 is a major tPA inhibitor, PAI-1 excess may affect placentation, increasing the risk of first trimester losses, preterm deliveries and intrauterine growth restriction. Our hypothesis was that prematurity was not the cause of neonatal hypoglycemia, but a parallel occurrence of a strong stimulus for maternal, fetal and neonatal production of insulin.
The objective of this study is to investigate the effect of metformin on the correlation between hyperinsulinemia and hypertension.
Acanthosis Nigricans is skin disease that associated with hyperinsulinemia. Clinical is velvety hyperpigmented plaques on neck, axilla, groin. If hyperinsulinemia is improved by treated with oral metformin and/ or diet control, acanthosis nigricans would be improved as well. Hyperpigmented plaques will be changed. We assess objective measurement by using spectroscopic and colorimetric analysis.
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 replace Sandostatine® in three daily subcutaneous injections by a single intramuscular injection of Sandostatine® LP per month in patients with a diffuse form of hyperinsulinism.
The purpose of this study is to determine whether the investigators' new imaging modality (111In-exendin-4) has advantages in detecting insulinomas in comparison to conventional imaging.
