15 Clinical Trials for Various Conditions
The purpose of this study is to examine the effect of rosiglitazone on limb fat and mitochondrial indices in HIV-1-infected subjects receiving stable antiretroviral therapy that does not contain stavudine (d4T) or zidovudine (AZT).
Lipoatrophy is a condition that affects certain individuals, most commonly those who are infected with the HIV virus. Lipoatrophy however can also affect individuals who suffer from recurrent systemic infections, those who have a weakened immune system, or certain patients who suffer from cancer or receive chemotherapeutics. In contrast, lipoatrophy can sometimes be present in individuals who are perfectly healthy but have genetically predisposing factors that can contribute to facial emaciation or lipoatrophy. The function of injectable fillers for the treatment of dermal contour deformities is to smooth dermal depressions formed by the loss of volume. These often elastic contour fillers (also known as soft tissue augmentation devices) can correct hollowness around the eyes, add fullness to thin lips, balance a disproportionate face or correct topographical anomalies. This study aims to: * Objectively measure the improvement of contour-deformities after Sculptra™ injection from baseline to study closure by utilizing the Primos™ photographic/topographical measuring system. * Evaluate the efficacy, longevity and duration of volume-correction in subjects which are both HIV positive and HIV negative. * Assess the safety of Scupltra™ dermal filler when used to correct volume deformities caused by lipoatrophy in subjects that are HIV negative.
Lipoatrophy, the loss of body fat from particular areas of the body, is a common side effect of antiretroviral therapy (ART). The purpose of this study was to determine the effectiveness of uridine supplementation in treating HIV infected individuals on stable ART with lipoatrophy.
HIV infected subjects receiving antiretroviral treatment for greater than 6 years with be evaluated for clinical lipoatrophy and mitochondrial function after switching nucleoside analogues from stavudine (d4T) to tenofovir treatment and after 4. Hypothesis: Tenofovir therapy will increase peripheral fat content as assessed by DEXA and mitochondrial function at 48 weeks.
The purpose of this study is to test the safety of Voluma and see what effects it has on HIV facial lipoatrophy. The hypothesis is that Voluma will be safe, efficacious and positively impact the quality-of-life in the treatment of facial lipoatrophy in patients with HIV.
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.
5 year, open-label study to evaluate safety of SCULPTRA on the signs of lipoatrophy of the face in at least 100 evaluable subjects with human immunodeficiency virus.
OBJECTIVES: I. Determine the response in plasma norepinephrine concentration and plasma glycerol to the agonist (clonidine) and the antagonist (yohimbine) of the alpha-2 adrenergic receptor in 6 patients with regional lipoatrophy and in 6 controls. II. Determine the full sequence of the alpha-2 adrenergic receptor structural gene in genomic DNA from peripheral blood leukocytes.
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.
This Phase 1, randomized, placebo-controlled, double-blind, healthy volunteer study tested the safety, tolerability, and plasma pharmacokinetics of two different concentrations of TAT4 Gel administered once daily to 50 cm2 of skin for 14 days.
The purposes of this study are to evaluate if switching an antiretroviral medication from efavirenz (EFV) to atazanavir/ ritonavir (ARV/r) will, in a 96-week period, change: 1. the amount of fat in HIV patients with lipoatrophy, 2. metabolic lab values such as your lipid (fat) profile, glucose (blood sugar), and insulin (a hormone that regulates glucose) in HIV patients with lipoatrophy.
This study is being done to better understand why people with HIV who have taken drugs for HIV begin to show abnormal changes in fat loss or fat gain in their bodies. This condition is called lipodystrophy. Patients who take medicine for HIV and who have lipodystrophy report loss of subcutaneous (sc) fat from the arms, legs, and face and excess fat gain in the neck and truncal region. They also more likely to have problems with insulin in the body, high fat levels in the blood and diabetes. The reason that lipodystrophy develops is not fully understood although some HIV drugs have are very likely the cause. The complications pose an increased risk of fat blockage forming in the arteries making you more at risk for heart problems in the future. Changes in body fat can cause physical discomfort and psychological distress. Management of these problems can be a challenge for the patient's doctor. The investigators propose data collection to determine if there is more than one reason why this might happen in some people and not in others. Laboratory samples being collected: 1) special imaging of the liver; 2) fat collected by needle from the mid thigh and mid-shoulder areas; 3) blood samples to measure the virus, t-cells, fats, and other markers of how the patient's body is handling the virus. This study is being done because science does not fully understand why some patients with HIV who take medicines for the virus have abnormal fat loss or gain and some do not. This research study is intended to help us better understand why and how this happens.
The purpose of this study is to observe the effects of certain anti-HIV medications on mitochondrial activity and fat cell death. This study will enroll participants from another study, ACTG A5202, who are on treatment regimens that do not include zidovudine, stavudine, or other thymidine-containing anti-HIV medications.
Nucleoside reverse transcriptase inhibitors (NRTIs) are a class of anti-HIV (Human Immunodeficiency Virus) 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.
