Active clinical trials for "Lipodystrophy"

The purpose of this clinical research study is to learn if human immunodeficiency virus (HIV)-infected subjects with abdominal fat accumulation on their highly active antiretroviral treatment (HAART) regimen have better changes in fat distribution after switching to atazanavir-ritonavir than those remaining on their current protease inhibitor boosted HAART regimen.

This study will evaluate the safety and effectiveness of leptin replacement therapy in patients with lipodystrophy (also called lipoatrophy). Patients have a total or partial loss of fat cells. They also lack the hormone leptin, which is produced by fat cells. The leptin deficiency usually causes high blood lipid (fat) levels and insulin resistance that may lead to diabetes. Patients may have hormone imbalances, fertility problems, large appetite, and liver disease due to fat accumulation. Patients age greater than or equal to 6 months with significant lipodystrophy may be eligible for this study. Participants will be admitted to the NIH Clinical Center for 10 days for the following studies before beginning 12 months of leptin therapy: Insulin tolerance test Ultrasound of the liver and, if abnormalities are found, possibly liver biopsies. Fasting blood tests Resting metabolic rate Magnetic resonance imaging of the liver and other organs, and of muscle and fat. Pelvic ultrasound in women to detect ovarian cysts. Estimation of body fat Oral glucose tolerance test Intravenous glucose tolerance test Appetite level and food intake Hormone function tests Questionnaires to assess activity and mood 24-hour urine collections Additional studies may include blood tests for genetic studies of lipodystrophy, a muscle biopsy to study muscle proteins involved in regulating energy expenditure before and after leptin replacement, and examination of a surgical specimen (if available) to study molecules that may be involved in energy storage and use. When the above tests are completed, leptin therapy begins. The drug is injected under the skin twice a day for 4 months and then once a day, if feasible. The dose is increased at the 1- and 2-month visits. Follow-up visits at 1, 2, 4, 6, 8 and 12 months after therapy starts include a physical examination, blood tests and a meeting with a dietitian. At the end of 12 months, all baseline studies described above are repeated. Patients record their symptoms weekly throughout the study. Those with diabetes measure their blood glucose levels daily before each meal and at bedtime.

The purpose of this study is to find out whether certain anti-HIV drugs (efavirenz [EFV] and nelfinavir [NFV]) affect the amount of certain fat-lowering drugs (atorvastatin, pravastatin, and simvastatin) in the blood. Protease inhibitors (PIs), a type of anti-HIV drug, are known to cause increased lipids (fats) in the blood of HIV-infected patients. EFV also is known to increase blood fats. HIV-infected patients who take PIs and/or EFV may need to take fat-lowering drugs to correct this problem. So it is important to look at possible drug interactions when these drugs are taken together. This study will see if taking EFV or NFV, a protease inhibitor, affects the blood level of simvastatin, atorvastatin, or pravastatin (all fat-lowering drugs). To obtain results more quickly, the study population will be healthy HIV-negative volunteers.

This study will evaluate the safety and efficacy of rotational fractional resection (RFR) to improve neck contouring. RFR is used to remove loose skin and fat.

The Research Question of the present study is the following: in a population of men and women presenting facial and neck dermal tissue defects (scars, hypertrophic scars, depressed plaques, and lipodystrophy defects) will linear hyaluronic acid (Jalucomplex®) significantly decrease and / or improve their appearance, results observed after 4 and 8 weeks?

The purpose of this study is to investigate whether a zinc-free insulin is an effective treatment option for lipoatrophy in patients with type 1 Diabetes (T1D) and insulin pump (CSII, continuous subcutaneous insulin infusion) therapy.

Artefill is an injectable facial filler device that is currently approved by the FDA for the correction of nasolabial folds. This study seeks to examine the use of Artefill in the treatment of HIV associated facial lipoatrophy. Facial lipoatrophy (facial fat loss) related to HIV is a stigmatizing condition characterized by loss of facial fat, most notably in the cheeks and temples.

The primary purpose of this study is to demonstrate the safety of injecting the Stromal Vascular Fraction (SVF) [containing Adipose Derived Stem Cells (ADSCs)] enriched fat grafts into regions of the face that require enhancement. The safety of SVF will be evaluated throughout the course of the study phase through the assessment of laboratory values, physical examinations, adverse events, safety phone calls etc.

PURPOSE: To evaluate the efficacy of shock waves extracorporea in improving body contour,decrease fat localized and appearance of gynoid lipodystrophy. SUBJECTS AND METHODS: A prospective and comparative longitudinal clinical study will be performed in 30 women with localized fat and gynoid lipodystrophy. Patients will be submitted data collection and assessments and before and after treatment. HYPOTHESES: It is expected that the patients will present improvement in the body contour, decrease fat localized and in the picture of the gynoid lipodystrophy after of the therapies. STATISTICAL ANALYSIS: A descriptive analysis will be done before and after vibration-oscillatory therapy, with frequency tables for categorical and descriptive variables (mean, standard deviation, median, minimum and maximum values) for continuous or numerical variables. In order to compare the main variables between the groups and the collection times, the analysis of variance (ANOVA) for repeated measurements will be used. Tukey's test will be used to compare groups. The level of significance adopted for the statistical tests will be 5% or p <0.05.

Combined antiretroviral therapy (cART) is associated with facial lipoatrophy, which is potentially stigmatizing for HIV-positive patients. Eutrophill is a 2.5% polyacrylamide hydrogel obtained by polymerization of acrylamide monomers with an official half-life of 5 years. Preliminary encouraging results with the use of polyacrylamide hydrogel for reconstruction of facial lipoatrophy in HIV-infected patients have been previously reported. The primary objective of the study was to evaluate the long-term efficacy and safety of subcutaneous facial injections of Eutrophill in HIV-infected patients with severe facial lipoatrophy as assessed by facial ultrasonography at screening , after 6, 12 and 24 months
