Active clinical trials for "Prediabetic State"

Schizophrenia is associated with a lifespan shortened by 20 years, due to cardiovascular disease (CVD), with antipsychotic (AP) medications understood to contribute to this risk through associated metabolic side-effects. Metformin, a medication used to treat prediabetes, and diabetes in the general population, holds promise with regard to reduction of AP-related metabolic problems, but has not been directly tested in early episode patients beyond weight loss, nor specifically in patients with diabetes or prediabetes and psychosis. We propose to replicate findings that metformin can reduce weight gain, and dysglycemia uniquely focusing on an early episode population diagnosed with prediabetes or diabetes. To help determine long-term risk/benefit of adjunctive metformin, we propose to look at changes in abdominal and liver fat, two well-established risk factors for CVD. Given links between dysglycemia, obesity with hippocampal volume loss and cognitive dysfunction, we will explore if improvements in metabolic indices are associated in changes in cognition and brain structure.

This randomized, double-blind, placebo-controlled, multi-site study is to reverse modest elevations of fasting blood sugar (prediabetes) and resting blood pressure(Prehypertension) or both co existing prediabetes and prehypertension by increasing blood levels of vitamin D. This may reduce the chances of developing diabetes or high blood pressure or both later in life.

This study evaluates exenatide, sitagliptin, and glimepiride for the treatment of high blood sugar in patients with impaired fasting glucose or early type 2 diabetes. The purpose of this study is to determine if exenatide and sitagliptin increase the amount of insulin made by the pancreas compared to glimepiride. It is hypothesized that exenatide or sitagliptin will sustain or increase the amount of insulin made by the pancreas in comparison to glimepiride.

The purpose of this study is to compare the safety and efficacy of two different amounts of vitamin D2 (600 or 4000 International Units/day) provided by mushrooms added to one of the daily meals versus same doses of vitamin D3 provided as oral supplements sold in any drugstore in reaching adequate or optimal blood levels of 25(OH)D in people with Vitamin D deficiency and pre-diabetes (high blood sugar without full blown diabetes) or the metabolic syndrome. Metabolic syndrome is the name of a group of risk factors that raise the risk for heart disease and other health problems, such as diabetes and stroke as described by the US department of Health and Human Services. This study will also attempt to demonstrate and compare the effect of the intervention with above two doses of vitamin D on blood levels of tests that show inflammation.

People with high fasting glucose can develop type 2 diabetes with the passage of time. This study is being done to determine the effect of a novel medication in people with this elevated fasting glucose. Sitagliptin is a substance that raises levels of a hormone normally found in the blood. This hormone, called glucagon-like peptide-1 (GLP-1), is normally released by the intestine in response to the presence of food. This hormone acts like a messenger between the intestine and the pancreas to raise insulin levels, and therefore, lower blood sugars. Sitagliptin is effective in people with diabetes, however, this study is being done to determine if Sitagliptin is effective in people with high fasting glucose who do not yet have diabetes.

This study will determine the effects of a supplement in reducing symptoms of metabolic syndrome, a collection of symptoms that increase the risk for developing heart disease, stroke, and diabetes.

The Ahmanson-UCLA Cardiomyopathy Center is conducting a clinical research study that will assess the use of the medication metformin to improve quality of life, exercise capacity, and improved outcomes in heart failure patients with pre-DM or early DM (type II). If the patient participates in this study, the patient will receive the drug metformin for approximately 3 months. During the study the patient will undergo comprehensive testing which includes blood draws and echocardiograms. The patient will also fill out a questionnaire. The patient must be 18 years old to participate.

The RISE Pediatric Medication Study is a 2-arm, 4-center, clinical trial of children with prediabetes and early type 2 diabetes to address the hypothesis that aggressive glucose lowering will lead to recovery of beta-cell function that will be sustained after withdrawal of treatment. Pediatric participants (ages 10-19) will be randomized to one of the following treatment regimens: (1) metformin alone or (2) early intensive treatment with basal insulin glargine followed by metformin. The primary clinical question RISE will address is: Are improvements in ß-cell function following 12 months of active treatment maintained for 3 months following the withdrawal of therapy? Secondary outcomes will assess durability of glucose tolerance following withdrawal of therapy, and whether biomarkers obtained in the fasting state predict parameters of ß-cell function, insulin sensitivity and glucose tolerance and the response to an intervention.

The purpose of this study is to evaluate if treatment with vitamin D increase beta cell function and insulin sensitivity in subjects with pre-diabetes or newly diagnosed diabetes mellitus type 2.

This is a six (6) month, single center, randomized, double-blind, parallel, controlled-feeding weight-loss study comparing two dietary groups (triglyceride and olestra) in pre-diabetic obese women.
