Filter by:The purpose of this study is to determine the mechanisms by which HIV protease inhibitors contribute to the development of diabetes in HIV-infected patients. The investigators propose that some HIV protease inhibitors impair insulin secretion and increase the production of glucose by the liver.
The purpose of this study is to determine whether attenuation/normalization of elevated blood sugar after meals ameliorates vessel wall (endothelial) function in individuals with insulin resistance.
Data supports diet induced obesity leads to activation of the IKK/NF-kB inflamatory pathway and that chronic inflammation leads to insulin resistance and diabetes. In rodents, salicylates inhibit IKK/NF-kB and may improve insulin sensitivity. We will study if this is true in people.
The purpose of this study is to test whether chronic administration of the drug acipimox will improve hyperlipidemia and insulin sensitivity among HIV infected patients experiencing highly active antiretroviral therapy (HAART) associated metabolic disturbances.
This study will evaluate the efficacy of diet and exercise (DE), with and without niacin and fenofibrate, in reducing the cardiovascular risk of patients with HIV lipodystrophy or dyslipidemia.
Insulin resistance is known to be associated with mood disorders and cognitive difficulties. The purpose of this study is to treat depressed patients with rosiglitazone (also known as [AKA] Avandia), therefore improving glucose sensitivity, which in turn has the potential to affect mood and thinking. We, the researchers at Stanford University, are recruiting men and women who have been diagnosed with depression, and are willing to participate in this 3 month study. Participation involves neuropsychological testing, 2 blood draws called an oral glucose tolerance test (oGTT), which tests for glucose and insulin levels, and the medication, rosiglitazone. Participants are allowed to continue on their current psychiatric medication.
This is a study with an approved drug for treating type 2 diabetes, for its effects on treating glucose and lipid abnormalities in patients being treated with first or second-generation antipsychotics, and comparison of effects of this drug with another treatment lifestyle modification. Patients who meet inclusion criteria will be treated with pioglitazone for 12 weeks. They will be evaluated for fasting glucose and lipids, glucose-tolerance tests, and neurocognitive battery and tests of verbal memory at baseline and during treatment with pioglitazone.
The purpose of this study is to determine whether the level of FOXA2 expression in fat tissue is a biomarker of insulin resistance. To test this hypothesis, we will perform euglycemic-hyperinsulinemic clamps in normal and obese human subjects to calculate insulin sensitivity, and see if insulin sensitivity correlates with the FOXA2 expression in subcutaneous fat.
The purpose of this study is to test the relationship between frequency of meals and hepatic fat content and insulin sensitivity. We, the researchers at Rockefeller University, hypothesize that low plasma insulin levels (as achieved by periods of fasting) will prevent insulin resistance and reduce hepatic lipid content. In contrast, frequent, carbohydrate-rich meals will predispose to hepatic steatosis (non-alcoholic) and insulin resistance. This is a 6 week inpatient study.
This investigation is being carried out to learn more about research findings from a study that was completed last year. Those findings revealed that within the skeletal muscle cells of individuals with type 2 diabetes, there was often damage to the mitochondria (the muscle cell's power source or the machinery of the muscle cell that produces energy). In individuals with type 2 diabetes, the liver continues to release sugar even when sugar levels are normal; the pancreas is not able to produce and release insulin normally; and the muscle and fat cells no longer respond as effectively to insulin. These defects lead to an abnormal rise of sugar in the blood. In this study, we want both to look more closely at the mitochondria and see if there is potential for improving mitochondrial functioning (improving the machinery of the muscle cell that produces energy) and reversing mitochondrial damage through a weight loss or a combined exercise/weight loss program. The program you get assigned to will be determined by a process called randomization (like a flip of a coin).
