View clinical trials related to Lipodystrophy.
Filter by:HIV lipodystrophy affects a significant proportion of patients treated with combination antiretroviral therapy (ART) and is characterized by excess visceral fat accumulation and loss of extremity and subcutaneous fat, in association with dyslipidemia and insulin resistance. Data from a previous randomized, placebo-controlled trial demonstrated that daily administration of 2mg TH9507, a growth hormone releasing factor (GRF), to HIV patients with an excess of abdominal fat accumulation for 12 weeks resulted in decreases in visceral adipose tissue (VAT) and trunk fat, with no significant changes in limb fat and subcutaneous adipose tissue (SAT). This study is aimed at further assessing the efficacy and safety of 2 mg TH9507 in a larger population of HIV patients treated with ART and experiencing an excess of abdominal fat accumulation.
The aim of this randomized study is to compare the occurrence of lipoatrophy in HIV-1 infected, naive patients receiving either a nucleoside reverse transcriptase inhibitor (NRTI)-sparing antiretroviral therapy with non-nucleoside reverse transcriptase inhibitor (NNRTI) and boosted protease inhibitor (PI), or a standard antiretroviral therapy with 2 NRTI plus either PI or NNRTI. Lipoatrophy is evaluated by measurement of fat volume by computed tomography (CT)-scan and DEXA (Dual Energy X-ray Absorptiometry).
The aim of this trial is to evaluate the impact on fat distribution of switching to NRTI-sparing regimens in lipoatrophic antiretroviral experienced patients with complete viral suppression. Maintenance of virological suppression and immunological factors are also assessed.
This is a randomized prospective study into metabolic adverse events during different types of initial antiretroviral therapy in HIV-1-infected men.
The purpose of this study is to investigate the effect of low-dose human growth hormone therapy on immune status and fat morphology.
Nucleoside reverse transcriptase inhibitors (NRTIs) are a class of anti-HIV drug that can be an important part of an HIV treatment regimen. Because anti-HIV therapy may have negative side effects, there is a great need to carefully study HIV infected patients on such regimens. One negative side effect observed in many HIV infected patients is lipoatrophy, a condition that results in fat loss in the body. It is unclear if NRTIs also have a role in the development of mitochondrial toxicity, a condition that affects the body's ability to produce energy. The purpose of this study is to observe the effects of an NRTI-based, protease inhibitor (PI)-sparing drug regimen on fat loss in HIV infected, treatment-naive adults. Study hypothesis: The initiation of NRTI-containing, PI-sparing therapy will inhibit mitochondrial DNA (mtDNA) synthesis and lead to a decrease in mtDNA content in adipose tissue, skeletal muscle and peripheral blood mononuclear cells (PBMCs), will cause deterioration in mitochondrial function, will increase fat apoptosis and oxidative damage biomarkers, and will lead to progressive decrease in body fat content.
HIV lipoatrophy is a condition marked by fat loss; it occurs in many patients taking antiretroviral (ARV) therapy that includes nucleoside reverse transcriptase inhibitors (NRTIs). Lipoatrophy may be related to mitochondrial toxicity, a condition that can damage the heart, nerves, muscles, kidneys, and liver, and can affect the body's ability to produce energy. NucleomaxX is a food supplement consisting of a sugar cane extract high in nucleosides, which are building blocks that may counteract the negative effects of NRTIs. Tenofovir disoproxil fumarate (TDF) is an NRTI that may cause less lipoatrophy than other drugs in its class, such as zidovudine (ZDV) or stavudine (d4T). The purpose of this study is to determine whether nucleoside supplementation with NucleomaxX and substitution of TDF for ZDV or d4T in an ARV regimen can reverse fat loss caused by mitochondrial toxicity in HIV infected adults. Study hypotheses: 1) The substitution of TDF for d4T or ZDV in patients with HIV lipoatrophy will result in an increase in mitochondrial DNA content in fat, skeletal muscle, and peripheral blood mononuclear cells (PBMCs), which in turn will lead to an improvement in mitochondrial function as assessed by electron transport chain (ETC) and oxidative phosphorylation pathway (OXPHOS) activity. The latter should lead to a decrease in fat apoptosis and in mitochondrial and lipid oxidative damage biomarkers. 2) Supplementation with uridine (via NucleomaxX) will increase mtDNA content in adipose tissue and increase body fat content.
This study will investigate long-term, low-dose growth hormone administration in HIV-infected patients with reduced growth hormone (GH) secretion and increased visceral adiposity. We hypothesize that low-dose growth hormone will reduce visceral fat. Secondary endpoints will include measures of insulin-like growth factor-1 (IGF-1), glucose homeostasis, lipids, blood pressure,bone density, cardiovascular risk and safety parameters.
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.
The purpose of this study is to assess the prevalence of metabolic and physical abnormalities in HIV infected (via mother-to-child transmission) and uninfected children and youth. Metabolism, body composition, bone density, and other factors will be assessed in relationship to participants' exposure to highly active antiretroviral therapy (HAART).
