Study type: Observational

The Visceral Adiposity Measurement and Observation Study

NCT ID: NCT04904406 Completed - HIV Infections Clinical Trials

Changes in Weight, Body Composition and Cardiac Risk After Discontinuing Abacavir Treatment in HIV-infected Individuals

AVERTAS
Start date: October 22, 2020
Phase: Phase 4
Study type: Interventional

Randomized controlled parallel open-label study in people living with HIV and at least 6 month of treatment with dolutegravir/abacavir/lamivudine prior to inclusion. Participants (n=95) are randomized to continue 3 drug-regimen dolutegravir/abacavir/lamivudine (control) or switch to two-drug regimen with dolutegravir/lamivudine (intervention). Follow-up is 48 weeks. Data is collected at baseline and week 48. Primary outcome is changes in weight from baseline of more than 2 kg. Secondary outcomes are changes in cardiac risk, composition and calcification of the heart tissue, and changes in body composition and metabolism, inflammation and coagulation. A MRI substudy is applied to focus on the cardiac adverse effects of abacavir.

NCT ID: NCT04903847 Recruiting - Obesity Clinical Trials

Changes in Weight, Body Composition and Metabolic Parameters After Discontinuing Dolutegravir or Tenofovir Disproxil

AVERTAS-2
Start date: February 2, 2021
Phase: Phase 4
Study type: Interventional

Randomized controlled parallel open-label study in persons living with HIV. The aim is to study weight changes in patients switching from a dolutegravir and tenofovir disoproxil containing regimen to either a dolutegravir or tenofovir disoproxil free regimen.

NCT ID: NCT03039491 Completed - Aging Clinical Trials

Immune Response to Pneumococcal Vaccination in Aging HIV Positive Adults

Start date: September 1, 2015
Phase: Early Phase 1
Study type: Interventional

The investigators hypothesized that pneumococcal vaccination with either the 23-valent pneumococcal polysaccharide vaccine PPV-23 (Pneumovax-23) alone or the 13-valent pneumococcal conjugate vaccine PCV-13 (Prevnar-13) followed by PPV-23 results in a similar antibody levels/functional antibody activity and induce similar pneumococcal polysaccharide (PPS)-specific B cell response in HIV positive individuals > 50 years of age, HIV positive individuals 21-40 years of age as compared to HIV negative > 50 years of age. The investigators immunized the study groups HIV+ persons >50, HIV+ persons 21-40 and controls (HIV negative) with PCV 13 followed by PPV23 and HIV>50 with PPV alone and examined immune responses to polysaccharide (PPS) 23 (F),14, 3, 7 (F) and 19 (A) using polysaccharide specific ELISA and opsonophagocytic assays (OPA). Pre- and post-immunization peripheral blood samples were obtained. Extensive B cell phenotype analysis using fluorescent antibodies was used to characterize PPS-labeled B cells. Specific phenotypes were correlated with antibody levels and OPA and compared to populations immunized with PPV

NCT ID: NCT01511016 Completed - HIV Lipodystrophy Clinical Trials

Leptin for Abnormal Lipid Kinetics in HIV Lipodystrophy Syndrome

Start date: February 2003
Phase: N/A
Study type: Interventional

"HIV lipodystrophy syndrome" (HLS) is characterized by loss of fat in the arms and legs, with increase in fat in the abdomen, and abnormal blood lipid levels. Persons with HLS have high risk for cardiovascular disease and diabetes mellitus and the metabolic syndrome. The investigators have previously shown that the abnormal lipid levels and lipodystrophy in HLS are associated with defective regulation of lipid metabolic rates, specifically, accelerated lipolysis (breakdown of stored fats), and decreased fat oxidation (utilization of fats for energy). Patients with HLS also have low levels of the hormone leptin. The investigators hypothesize that treatment of these patients with leptin will improve fat oxidation and may slow the rate of lipolysis. Hence, the investigators propose to study the effect of leptin therapy on lipid metabolic rates and lipid and glucose levels in adults with HLS. The investigators will use state of the art stable isotope tracer techniques and gas chromatography mass spectrometry (GCMS) to measure lipolysis, fat oxidation, and fat re-esterification in adipose tissues and liver.

NCT ID: NCT01329744 Terminated - HIV Lipodystrophy Clinical Trials

Effects of IGF-I in HIV Metabolic Disease

Start date: June 2011
Phase: Phase 1
Study type: Interventional

This study examines the effects of recombinant insulin like growth factor - I on body composition, glucose homeostasis, and lipids, in adults with HIV infection and signs of metabolic disease.

NCT ID: NCT01263717 Completed - HIV Clinical Trials

Effects of Growth Hormone Releasing Hormone in HIV

Start date: December 2010
Phase: N/A
Study type: Interventional

HIV-infection and its treatment are often associated with an increase in belly fat, as well as abnormal cholesterol and problems metabolizing sugar. People with HIV infection and increased belly fat often have decreased growth hormone (GH) levels. Low GH levels may contribute independently to increased belly fat and to increased cardiovascular risk through effects on sugar metabolism, inflammation, and other mechanisms. Tesamorelin, a growth hormone releasing hormone (GHRH) analogue, has been shown to to reduce belly fat in patients with HIV-associated abdominal fat accumulation. However, the effects of tesamorelin on fat accumulation in the liver and muscle, sugar metabolism, and cardiovascular health are not yet known. The current study is designed to determine the effects of tesamorelin treatment on fat accumulation in the muscle and liver, insulin sensitivity and sugar metabolism, and markers of cardiovascular health including blood vessel thickness (carotid intima media thickness [cIMT]) and markers of inflammation in the body. The investigators hypothesize that tesamorelin will decrease fat accumulation in the liver and muscle and will decrease markers of inflammation, with either neutral or beneficial effects on glucose metabolism.

NCT ID: NCT00795210 Completed - HIV Lipodystrophy Clinical Trials

Effects of Short-term Growth Hormone in HIV-infected Patients

Start date: February 2009
Phase: N/A
Study type: Interventional

The purpose of this study is to examine the short-term effects of two different doses of growth hormone, compared to treatment with growth hormone releasing hormone, on the brain's secretion of growth hormone and the body's glucose metabolism. We hypothesize that growth hormone administration will alter the body's endogenous pulsatile growth hormone secretion and that higher dose growth hormone may decrease insulin sensitivity. We hypothesize that growth hormone releasing hormone will augment endogenous GH pulsatility and be neutral to insulin sensitivity.

NCT ID: NCT00656851 Completed - HIV Infections Clinical Trials

Myocardial Function & FFA Metabolism in HIV Metabolic Syndrome

WU197
Start date: September 2005
Phase: N/A
Study type: Interventional

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.

NCT ID: NCT00627380 Completed - Hypertension Clinical Trials

Yoga for the Management of HIV-Metabolic Syndromes

Start date: November 2005
Phase: Phase 4
Study type: Interventional

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.
