View clinical trials related to Prediabetic State.
Filter by: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.
Weight loss achieved through gastric banding will be superior to treatment with metformin in preserving or restoring pancreatic beta cell function in people with prediabetes or mild type 2 diabetes.
This study will investigate whether real-time continuous glucose monitoring can be used as a tool for behavior change in people with pre-diabetes.
The main objective of the study is to understand the pathophysiological mechanisms involved in switching from pre-diabetes to type 2 diabetes and to identify new biomarkers of type 2 diabetes risk in the population of patients with pre-diabetes.
Assessment of glucose metabolism and liver fat after 12 week dietary intervention in pre diabetes subjects. Subjects will be randomized to either high fat (olive oil supplemented),high carb/high fiber (beans supplemented) and high carb/low fiber diets. Glucose metabolism will be assessed by labeled oral glucose tolerance test and liver fat by magnetic resonance spectroscopy pre randomization and at 8 and 12 week after starting dietary intervention.
This study aims to investigate the effect of a cobiotic formulation, prepared as a smoothie beverage, on the ratio of intestinal microbiota of the Bacteroidetes phylum to those of the Firmicutes phylum in the stool as well as the effect on insulin resistance, gut hormones (PYY) Peptide YY and (GLP-1) Glucagon-like Peptide, ghrelin with perceptions of appetite and satiety.
In an ongoing study new dental patients are screened to determine their risk of having undiagnosed pre-diabetes or diabetes based on risk factors readily known by the patient and signs of gum disease. Investigators further seek to assess if a post-identification intervention leads to a greater likelihood of study participants identified as potentially pre-diabetic or diabetic visiting their physician regarding their screening blood test results, and to improved health outcomes.
The purpose of this study is to determine the effect of a slowly digesting starch on gut bacteria, sugar and fat metabolism, hunger hormones, and body fat in people with pre-diabetes.
The purpose of this study is to evaluate the impact of a worksite lifestyle intervention for diabetes prevention among employees with prediabetes.
Objective of this study is to determine the safety and efficacy of administration of herbal supplements (Salacia leaf extract, Salacia root extract and Sesame seed extract) for 6 weeks in the management of prediabetes and mild to moderate hyperlipidemia.
