Filter by: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.

This study involves research about an investigational medicine called metreleptin. The reason for this study is to find out how metreleptin can improve non-alcoholic steatohepatitis or nonalcoholic fatty liver disease associated with lipodystrophy, a rare disorder associated with abnormal loss of the body's fat tissue. In this study, metreleptin is considered to be investigational for the treatment of lipodystrophy. Metreleptin will be given via injections under the skin. We plan to continue therapy for a period of one year and evaluate the change in liver disease by a liver biopsy. We will also follow the metabolic parameters (e.g. blood cholesterol, liver function, insulin resistance) and body composition characteristics (e.g. the pattern of fat distribution in the body).
The purpose of this study is to evaluate the safety and effectiveness of the Cabochon System for the improvement in the appearance of cellulite.
This purpose of this study is to examine the relationship between insulin resistance and changes in body fat distribution in HIV-infected persons. This study measures insulin sensitivity, abdominal fat, and intramuscular fat in HIV-infected persons and examines the effect of an anti-diabetic drug (metformin or pioglitazone) on insulin sensitivity and body fat in this population.
"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.
The hypotheses of this study were that: 1. HIV lipodystrophy is associated with psychological morbidity relating to body image, anxiety and depression. 2. Treatment of HIV lipodystrophy using autologous fat transfer, polylactic acid or Bio-alcamid, is associated with an improvement in psychological morbidity and anatomical volume of treated areas. 3. The DI3D system is a valid and reproducible method of recording and measuring facial 3-D volume.
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.
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.
