Filter by:Our aim is to investigate the effects of a 12-week structured aerobic exercise on fasting and 2 h glucose, insulin and lipid concentrations in sedentary overweight subjects in whom impaired fasting glucose and/or impaired glucose tolerance was observed for the first time.
It is known that small dense LDL particles are associated with an increased cardiovascular risk. LDL particles can be separated by gradient gel electrophoresis (GGE) according to their size. The risk to suffer from coronary heart disease is 3-7 fold elevated in subjects with small dense LDL particles compared to subjects with large LDL particles. This study aims at evaluating the predictive value of small dense LDL particles in patients with prediabetes and type 2 diabetes mellitus concerning future changes in intima media thickness, flow-mediated dilation and other risk factors of atherosclerosis (e.g. insulin resistance). 60 patients with prediabetes or type 2 diabetes will be recruited for the study. Assessment will include medical history (risk factors), physical examination (blood pressure, BMI, waist-to-hip ratio), collection of serum, oral glucose tolerance test, measurement of intima media thickness and endothelial dysfunction by ultrasound. All measurements will be repeated after 2 years. Data will be analysed to assess whether the amount of small dense LDL particles can predict further structural and functional changes of the cardiovascular system or changes in the severity of the disease (insulin resistance).
The Karachi-based Pakistan Diabetes Prevention Study aims to address key issues in the prevention of type 2 diabetes. Approximately 20,000 people From four communities will be screened for diabetes risk factors using a non-invasive diabetes risk-score system. Those found to be at increased risk will be given an oral glucose tolerance test. People who, after the oral glucose tolerance test, are identified as having prediabetes will have the opportunity to take part in the Pakistan Diabetes Prevention Study lifestyle intervention. This consists of culturally adjusted preventive strategies focusing on diet and physical activity in real-life settings. Another important aspect of this trial will be to assess the impact of urban planning on the prevalence of obesity and diabetes.
The main objective of the study is to follow prospectively a cohort of patients with pre-diabetes 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 this population.
Hypothesis: A high cardiovascular risk is present in subjects with pre-diabetes in Hong Kong Chinese. The investigators plan to assess Chinese subjects in Hong Kong who have pre-diabetes (impaired fasting glucose, IFG; or impaired glucose tolerance, IGT) based on oral glucose tolerance test (OGTT) on their cardiovascular risk status such as obesity, hypertension and lipid profile.
The relationship between obesity and insulin resistance is known, however the mechanism(s) associating obesity with insulin resistance is not well understood. Inflammation and accumulation of fat in non fat tissue (like muscle) are conditions found on obesity which could be the potential link between obesity and insulin resistance. This study is designed to test the effects of two different drugs on numerous features of the obesity and insulin resistance in subjects with impaired glucose tolerance. Impaired glucose tolerance is a condition where blood sugar is too high after drinking a sugary drink containing 75 grams of sugar. Impaired glucose tolerant subjects are insulin resistant and at risk of developing diabetes. The drugs to be used are fenofibrate and pioglitazone. Fenofibrate is used to reduce the amount of fat (triglycerides) in the blood while pioglitazone is routinely used to make the body more sensitive to insulin in patients with diabetes. The purpose of this study is to compare the effects of either of these two medications (pioglitazone and fenofibrate) alone or the combination of both on fat accumulation in body (muscle) and inflammation. The amount of fat accumulation in muscle is thought to affect insulin sensitivity. In addition, the changes in the level of proteins produced by fat tissues will be studied in response to the two medications in this study. These proteins are thought to be involved in diabetes and insulin resistance. These studies are designed to examine fundamental clinical mechanisms underlying the metabolic syndrome and diabetes.
