17 Clinical Trials for Various Conditions
We hypothesize that the hearts of HIV+ people with The Metabolic Syndrome use and oxidize fats and sugars inappropriately, and that this may impair the heart's ability to pump blood. We hypothesize that exercise training or pioglitazone (Actos) will improve fat and sugar metabolism in the hearts of HIV+ people with The Metabolic Syndrome. This study will advance our understanding of cardiovascular disease in HIV+ people, and will test the efficacy of exercise training and pioglitazone for improving insulin resistance, heart metabolism and heart function in this at risk population.
The purpose is to examine the safety and efficacy of 16wks of pioglitazone (Actos; 30mg/d) with and without aerobic and strength exercise training for reducing glucose intolerance and central adiposity in HIV-infected people. We anticipate that pioglitazone + exercise training will improve glucose metabolism and insulin sensitivity, and reduce central adiposity more than pioglitazone alone. These improvements should translate into reduced cardiovascular disease risk in HIV-infected people.
We are testing the safety and efficacy of a 16-wk yoga lifestyle intervention on oral glucose tolerance, fasting lipid/lipoprotein levels, body composition, cardiovascular function, quality of life, CD4+ T-cell counts and viral load in HIV-infected men and women with components of The Metabolic Syndrome. We hypothesize that a yoga lifestyle intervention will improve metabolic, anthropometric, cardiovascular disease parameters, and quality of life domains without adversely affecting immune or virologic status in people living with HIV.
This study is designed to determine the effects of an intensive lifestyle modification program in patients with HIV and Metabolic Syndrome. The primary endpoints will be improvement in body composition, specifically waist-to-hip ratio (WHR). The secondary endpoints will include improvement of cardiovascular indices, such as total cholesterol, low-density lipoprotein (LDL), high-density lipoprotein (HDL), and triglyceride cholesterol levels, blood pressure, cardiac enzymes, c-reactive protein (CRP), tissue plasminogen activator (t-PA), plasminogen activator inhibitor (PAI), and insulin and glucose metabolism. We expect that quality of life indices and life skills should also improve with the lifestyle modification program.
Obese HIV-positive women with Metabolic Syndrome (HIV-MS) and obese HIV-negative women with Metabolic Syndrome will be studied before and after achieving moderate (6%-8%) diet-induced weight loss. The investigators hypothesize that health markers will improve in both groups but that the improvement will be blunted in the women with HIV-MS.
The purpose of this study is to examine whether replacing leptin to normal levels can reverse the changes in fat distribution, lipid profile, and other metabolic problems associated with highly active antiretroviral therapy (HAART)-induced lipodystrophy and metabolic syndrome in HIV patients.
The purpose of this study is to investigate the effects of the nutritional supplement rice bran arabinoxylan compound (RBAC) on metabolic syndrome variables in persons living with HIV. The hypothesis is that there will be a significant improvement in metabolic syndrome and immune variables in HIV-positive participants in the intervention group compared to the control group.
The purpose of this study was to evaluate the effects of semaglutide on intra-hepatic triglyceride (IHTG) content in people living with HIV (PLWH), central adiposity, insulin resistance or pre-diabetes, and hepatic steatosis.
Background: Weight gain can lead to obesity and diabetes even in people living with human immunodeficiency virus (HIV). Researchers want to see if the technique intermittent calorie restriction can help overweight people with HIV as an alternative to traditional diets. Objective: To see if intermittent calorie restriction leads to weight loss and improved blood sugar in obese people with HIV. Eligibility: Adults ages 18-65 with HIV who are obese and do not have diabetes Design: Participants will be screened with a medical history, physical exam, and blood and urine tests. Before starting treatment, participants will: * Have a nutritional consultation * Get a pedometer to record daily steps * Test a restricted diet for 1 day * Have a body x-ray At the baseline visit, participants will have: * Blood drawn after they drink a sugar drink * Questions about their health and eating * A nutritional consultation * Resting energy expenditure measured. Participants will fast overnight. Then they will lie down while a plastic bubble goes over the head and a plastic sheet covers the upper body. Oxygen flows into the bubble. * Liver stiffness test. A wand on the stomach releases sound waves like an ultrasound. For 12 weeks, some participants will be on a standard diet. Others will restrict how much food they eat 2 days a week. On those days they will eat about 25% of their recommended calories. Participants will keep a diary of their diet and steps. Participants will have 4 visits during the 12-week diet and 1 visit 12 weeks after the diet ends. They will repeat previous tests.
This study will test the effect of liraglutide on cognitive function in HIV-infected overweight or obese subjects with type 2 diabetes.
This study will examine the following: 1) how common albuminuria and proteinuria are among HIV-positive patients, 2) what causes albuminuria or proteinuria in these patients and 3) whether the condition becomes more severe over time. HIV-infected people are more likely than others to develop kidney disease. The earliest indicator of the possible presence of kidney disease is albuminuria (increased amounts of the protein albumin in the urine). A later indicator is the appearance of other proteins, a condition called proteinuria. HIV-infected patients 8 years of age and older who do not have diabetes, chronic kidney disease or cancer may be eligible for this study. Participants provide a urine sample during three visits as follows: the first upon enrollment in the study, a second 3 months later, and a third about 6 months after that. Blood samples are drawn at the first and last visits. At the first visit a medical history is taken and blood pressure, height, weight, waist circumference, hip circumference and upper arm skin thickness are measured. Participants who are found to have albuminuria or proteinuria are asked to undergo a kidney biopsy for research purposes. The procedure is optional. Participants who develop heavy proteinuria may be recommended to undergo a kidney biopsy in order to determine the nature of the kidney disease and begin treatment. The biopsy requires a 2-day hospital stay. For the procedure, an anesthetic is given to numb the skin and a needle is inserted and guided into the kidney to withdraw a small tissue sample. The needle is passed twice, and possibly three times. Following the procedure, the subject remains in bed rest for at least 10 hours to minimize the risk of excessive bleeding.
A healthy diet and exercise have improved the health of people without human immunodeficiency virus (HIV) who have Metabolic Syndrome. In this study we would like to find out if the same benefit can be seen in people with HIV and Metabolic Syndrome. Patients with Metabolic Syndrome usually have a large waist, high blood cholesterol levels, high blood pressure, and high blood sugar levels. These are risk factors, which may increase one's chance of developing heart disease and/or diabetes. The purpose of the study is to evaluate the effects of different methods of treating HIV associated Metabolic Syndrome. The groups are: 1) a lifestyle modification program plus metformin (also known as glucophage), 2) lifestyle modification plus placebo, 3) metformin alone or 4) placebo alone. The lifestyle modification program consists of nutrition and exercise sessions with the goal of improving body composition, heart health, and ways to lower the risk of developing diabetes.
The purpose of this study is to determine whether patients with HIV lipodystrophy (fat wasting) benefit from taking the combination of two drugs, one insulin sensitizer (either metformin or pioglitazone, both diabetes drugs) and leptin (a natural hormone produced by your fat cells). Our hope is that they will improve sugar and fat metabolism and positively affect the body fat changes you have noticed while taking HAART.
The purpose of the study is to determine if the combination of recombinant human growth hormone plus rosiglitazone (an insulin-sensitizing drug) is safe and more effective than either drug alone (or no active therapy) for the treatment of fat accumulation in people with HIV infection and insulin resistance.
Switching patients with HIV infection from tenofovir disoproxil fumarate (TDF) to a tenofovir alafenamide (TAF) based drug regimen can provide many safety benefits including preserving bone mineral density and kidney function. This study will examine metabolic changes that patients may encounter due to the switch in medication regimens and the maintenance of viral suppression.
The purpose of this study is determine whether different antiretroviral therapy (ART) changes the effects on body fat and predict the weight change in Black and Hispanic females.
The purpose of this study is to see if there are any changes in sugar and fat levels in the blood when patients take anti-HIV therapy for many years. Another goal is to test memory and mental concentrations to determine if anti-HIV drugs protect the brain from damage caused by HIV. (The purpose of this study has been changed from the original version.) HIV-infected patients with low CD4 cell counts are at risk for getting opportunistic (AIDS-related) infections. CD4 cells are cells of the immune system that help fight infection. Anti-HIV therapy may increase CD4 counts, which may lead to a decrease in AIDS-related infections. Problems that anti-HIV therapy is associated with include metabolic problems, neurologic problems, abnormal opportunistic infections, and cancer. Patients in ACTG 362 have been exposed to anti-HIV therapy longer than any other large group in the ACTG. These patients appear to benefit from their therapy, but also suffer problems from it. Observation of these patients should provide more information about long-term anti-HIV treatment and may detect unexpected problems. (This study as been changed. More information about the reasons for conducting this study has been added.)
