Active clinical trials for "Glucose Intolerance"

It is well known that Chitosan oligosaccharide is low molecular weight and water soluble and chitosan oligosaccharide has been shown to reduce blood cholesterol and blood pressure, increase immunity, and enhance antitumor properties. the effect of chitosan oligosaccharide (GO2KA1) supplementation on glucose control in subjects with normal blood glucose, impaired fasting glucose and impaired glucose tolerance.

The aim of this study is to compare the dual task task in individuals with prediabetes and diabetes. According to the results of this study, if there is a difference in dual-task performances and other conditions between people with prediabetes and people with diabetes, it will be a reference study for intervention studies accordingly.

Prediabetes (PD) was defined as an state in which glucose levels are above normal but not enough to meet criteria for the diagnosis of type 2 diabetes (T2D). PD can be presented as impaired fasting glucose (IFG), impaired glucose tolerance (IGT) and glycated hemoglobin A1c (A1C) altered. The International Diabetes Federation (IDF) reported that in 2013 the prevalence of IGT was 6.9% which is equivalent to approximately 316 million individuals with IGT, it is expected that by 2035 this number will increase to 417 million people affected. Many hypoglycemic effects attributed to Gymnema sylvestre have been reported, including: increase of insulin secretion, regeneration of pancreatic islet cells, increased glucose utilization in various ways and inhibition of glucose uptake in the intestine.

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.

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.

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.

The purpose of this study is to determine whether Rubus occidentalis extract could improve fasting or postprandial serum glucose levels, and related metabolic markers among patients with prediabetes (impaired fasting glucose and/or impaired glucose tolerance).

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

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.
