Active clinical trials for "Prediabetic State"

The goal of the present research is to compare the effects of treatment with metformin and sitagliptin, alone or in association, in women with previous gestational diabetes to evaluate the impact of the two drugs on beta-cell function. The study results may contribute to give a rational approach for future investigations.

Pre-diabetes, a condition characterized by hyperglycaemia, is associated with increased cardiovascular risk and reduced life expectancy, as compared to the general population. AMP-activated protein kinase (AMPK) is an enzyme that plays a key role in cellular energy homeostasis and metabolism, and recently it has been demonstrated that AMPK regulates aging pathways, as well. AMPK is susceptible to modulation through pharmacologic (e.g. metformin) and non-pharmacologic (e.g. physical exercise) interventions. This clinical trial aims to describe the effects of the AMPK pathway on longevity genes and inflammation in the setting of pre-diabetes in vivo and in vitro. To this end, the investigators will compare treatment with metformin (500 mg t.i.d) for 2 months, versus placebo in pre-diabetic subjects. The investigators will assess expression of longevity genes SIRT1, p66Shc, p53 and mTOR in peripheral blood mononuclear cells (PBMCs) ex vivo. The investigators will evaluate monocyte polarization by flow cytometry, according to the expression of surface antigens (CD68, CCR2, CD163, CD206, CX3CR1) to determine the prevalence of pro- or anti-inflammatory cells. Inflammatory cytokines (TNF-alpha, MCP-1, IL-1, IL-6, IL-10, CCL12) will also be determined. In the in vitro study the investigators will evaluate the effects of AMPK activation or inhibition on longevity gene and protein expression.

This study builds on data that high-density lipoprotein (HDL) has a number of potentially beneficial effects including directly modulating glucose metabolism through multiple mechanisms. The primary objective of this study is to determine the effects of RVX000222 on postprandial plasma glucose in male individuals with impaired fasting glucose (IFG) or impaired glucose tolerance (IGT), during a frequently sampled oral glucose tolerance test (OGTT).

Most new mothers in the United States will start off breastfeeding. For some mothers, despite following best practices, they are not able to meet their breastfeeding goals due to unexplained low milk supply. At the same time, nearly 1 in 4 new mothers are pre-diabetic (elevated blood sugar, but not yet diabetic). My progression of research suggests that the same metabolic factors causing pre-diabetes may also be causing low milk supply. Metformin is a widely prescribed drug to treat high blood sugar. This study is a preliminary, small scale randomized trial designed to test for a trend in the hypothesis that metformin is safe and potentially effective in treating low milk supply in insulin resistant and pre-diabetic mothers.

This project addresses cardiovascular disease risk in patients with prediabetes. Levels of lipids after eating a meal ("postprandial lipids") are strong independent predictors of cardiovascular risk. Newer anti-diabetic agents - exenatide and saxagliptin - impact lipid metabolism. These medications will be studied for their effect in reducing both postprandial lipid levels and arterial dysfunction.

The study will evaluate the effects of resveratrol/leucine and resveratrol/HMB for their ability to control glucose levels in persons without diabetes but with impaired fasting glucose. Secondary assessments will examine the effect of these nutritional supplements versus placebo on inflammation, fasting lipids, HbA1C, and fructosamine, longer term metabolic markers of risk in diabetes.

The investigators hypothesize that sitagliptin will significantly reduce impairments in insulin secretion and insulin resistance resulting from short-term oral glucocorticoid therapy.

Original research article entitled Induced and Controlled Dietary Ketosis as a Regulator of Obesity and Metabolic Syndrome by Madeline Gibas for consideration for publication in a clinical journal. This research manuscript builds on previous landmark studies that report that major weight and fat mass loss in type II (T2D) patients who were fed a very low carbohydrate, ketogenic diet. In this manuscript, the investigators outline our research study that showed statistically significant (p < 0.05) changes over time in hemoglobin A1c, weight, BMI, body fat percentage and ketones for patients with metabolic syndrome who were fed a very low carbohydrate diet, ketogenic diet.

The primary purpose of this research is to demonstrate the therapeutic effects of implementing a well-formulated low carbohydrate lifestyle program over 2 years in patients with type 2 diabetes, pre-diabetes, and metabolic syndrome.

Researchers are trying to determine if an anti-diabetes medication, called Exenatide SR, is well tolerated in kidney transplant patients with elevated blood glucose levels, and if it's effective in preventing diabetes.
