Active clinical trials for "Lipodystrophy"

Background: - Lipodystrophy is a condition where people do not have enough fat in the body. People with lipodystrophy can have problems such as diabetes or an enlarged liver. Researchers are looking at how leptin, a hormone produced by fat cells, can help people with these problems. Leptin helps control appetite and how the body stores food. Taking leptin can help people with lipodystrophy eat less food, which may help treat diabetes and other problems. To better understand how leptin works, researchers want to do an inpatient study on leptin treatment in people with lipodystrophy. Objectives: - To study how leptin treatment affects lipodystrophy. Eligibility: - Individuals between 14 and 70 years of age who have lipodystrophy. Design: All participants will have a 19-day stay at the National Institutes of Health Clinical Center. One group of participants will have tests for 5 days before starting to take leptin. They will then take leptin for 2 weeks, and have more tests. The other group of participants will have tests for 5 days while taking leptin. They will then take stop taking leptin for 2 weeks, and have more tests, and then they will start taking leptin again. Participants will have regular blood and urine tests during the visit. Some of the blood tests will look at insulin levels. Some will look at how the body metabolizes sugar and fat. Other tests will check hormone levels, especially of reproductive hormones. During the visit, participants will spend 3 separate days in a metabolic chamber, a special room that measures how many calories the body uses. Urine samples will be collected during these stays. Participants will also have several body imaging studies, including magnetic resonance imaging and a body composition scan. Physical activity will be tested with an exercise bicycle and an electronic activity monitor. Participants will be asked questions about hunger and comfort levels throughout the stay.

The objective of this single patient study is to assess the safety and efficacy of setmelanotide as a treatment of severe metabolic abnormalities resulting from LD, especially refractory hypertriglyceridemia leading to recurrent bouts of pancreatitis.

This is a single-center, open-label study to evaluate the efficacy of AKCEA-ANGPTL3-LRx for reduction of fasting triglycerides in participants with familial partial lipodystrophy.

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.

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.

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.

Ritonavir-boosted protease inhibitor (PI) regimens have become a backbone for treatment of people with HIV. However, adverse drug effects, particularly lipodystrophy/lipoatrophy are closely associated with these regimens. Therefore, there is a need for a drug with comparable effectiveness to the ritonavir boosted PIs without the side effects of dyslipidemia, which has been associated with elevated cholesterol and cardiovascular disease Raltegravir is an HIV integrase inhibitor in phase III clinical development. To date there are no approved drugs that target the same stage of the HIV-1 lifecycle. However, data from studies indicate that raltegravir is generally safe and well tolerated and has strong antiretroviral activity when used in combination with licensed antiretroviral medications. This study aims to demonstrate that patients substituting raltegravir for a PI or NNRTI based antiretroviral regimen will be associated with a 10% reduction in body fat over 24 weeks. The study will consist of a total of 10 subject visits over a period of 48 weeks. Approximately 40 female patients will participate in this study (approximately 10 at UCLA).

To determine the efficacy and safety of 4 therapeutic interventions on HAART-Induced lipodystrophy. The interventions are: 1) Dietary - the effect of a high carbohydrate vs.a high cis-monounsaturated fatty acid diet. 2) The effect of aerobic exercise with dietary advice. 3) The effect of Omega-3 Fish Oil Capsules. 4) The effect of leptin therapy. These interventions are aimed at improving the metabolic complications of HAART therapy such as elevated lipids, and insulin resistance or diabetes.

The metabolic and molecular basis of lipodystrophy syndrome in HIV-infected patients is not known. Whether besides protease inhibitors, other antiretroviral drugs, HIV infection and reduction in viral load contribute to the development of lipodystrophy syndrome is not clear. The project therefore has the following aims: 1) to characterize metabolic abnormalities and changes in body fat distribution, 2) to develop objective criteria for defining the syndrome and to ascertain prognostic indicators and 3) to elucidate the molecular basis of the lipodystrophy syndrome in HIV-infected patients.

The primary objective of the study is to determine if Serostim® 4 mg administered daily for 12 weeks as treatment for the abnormal fat accumulation and distribution associated with HIV-associated Adipose Redistribution Syndrome (HARS) reduces Visceral Adipose Tissue (VAT, measured by CT scan) more effectively than placebo.
