Filter by:This is a randomized placebo-controlled trial to examine if once daily probiotic therapy will lower serum LPS levels and immune activation among HIV-infected youth.
DMPA (depot medroxyprogesterone acetate or the 'depot' injection) is a widely used contraception. It is popular in woman with HIV as it probably still works when you take HIV drugs. HIV drugs can increase or decrease the level of other drugs (e.g. contraceptives) in your bloodstream which may make them work less well or increase side effects. It is assumed that DMPA can be given with HIV drugs there are no studies proving this. The purpose of the study is to investigate whether an HIV drug combination containing lopinavir/ritonavir affects DMPA when they are taken at the same time.
This is a multi-center study designed to assess the accuracy of Pima™ CD4 Test to enumerate CD4+ T-cells in whole blood over the measurement range expected for the intended population. The Pima CD4 Test consists of the Pima™ CD4 cartridge and Pima™ Analyzer to identify and determine the absolute counts of mature helper (CD3+/CD4+) T-lymphocytes in whole blood.
To assess the maternal and infant safety of a single daily fixed-dose combination of TDF/FTC/EFV (Atripla®), compared to the association of LPV/r (Kaletra® or Aluvia®) and 3TC/ZDV (Combivir®) given to African women to prevent overall MTCT in populations practicing breastfeeding.
The reduction with antiretroviral therapy (ART) of HIV RNA in blood, and HIV RNA in infected cells and in viruses associated with the follicular dendritic cell (FDC) network in lymphatic tissues, typically follows a two-phase pattern of decline. The half-life of the first-phase is about 1 day and that of the second phase is about 14 days, with comparable estimates for first-phase decay in SIV-infected rhesus macaques. While substantial evidence supports the current view that first-phase decay reflects the death of activated CD4+ T cells infected before ART was begun, the sources of viral RNA in the second phase have not as yet been conclusively established. Possible sources of viral RNA that have been invoked in mathematical models, or for which there is experimental evidence, include longer-lived infected cells such as macrophages and resting CD4+ T cells, dissociation of virus from the FDC network, and productively infected CD4+ T cells that are not subject to clearance by host immune responses because of waning levels of HIV antigen. Raltegravir (MK-0518) belongs to a new class of integrase inhibitors that potently suppress HIV and SIV replication, and reportedly markedly alters the second phase HIV decline in a way that challenges the current view that longer-lived infected cells are the source of virus in this phase. While mathematical modeling of decay of HIV RNA in blood was most consistent with 1) cells newly infected by long-lived cells, or 2) from activation of latently infected cells with full-length unintegrated HIV DNA as a source of second phase virus, we think the data are also quite consistent with the greater efficacy of integrase inhibitors in a particular cell type and/or anatomic site such as the gut. In this protocol we will test the hypothesis that the rapid decrease in HIV replication associated with raltegravir is due to a more complete suppression of viral replication in lymphatic compartments such as lymph nodes and gastrointestinal lymphatic tissue. We will also investigate compartment-specific intracellular levels of raltegravir to potentially explain differences in changes in these compartments.
This is a randomized double blind clinical trial to test the effect of Naltrexone on HIV infected heavy drinkers. The study will select 40 HIV positive patients who meet criteria for heavy drinking. Treatments include Naltrexone (25-100mg)and placebo. Patients will be treated, followed up, and assessed for a duration of 12 weeks. The investigators associated hypotheses Hypothesis 1: Naltrexone will reduce the frequency of heavy drinking. Hypothesis 2: Naltrexone will lead to maintenance or improvement in CD4 lymphocyte count and decreased HIV RNA levels. Hypothesis 3: Naltrexone will lead to a reduction in sexual risk behaviors. Hypothesis 4: Naltrexone will lead to improved adherence to HAART. Hypothesis 5 (Exploratory): Naltrexone will be well-tolerated with minimal side effects and patients will exhibit good treatment retention.
The objective of this proposal is based on the assumption that the HIV infected Ethiopian population responded in a different way in comparison to the Caucasian subjects to Lopinavir therapy. Our preliminary data demonstrated that Ethiopian's have different Lopinavir serum concentration in comparison to non-Ethiopian's. For these reasons the plan of this study is to investigate the pharmacokinetic/pharmacodynamic (PK/PD) profile in both populations. The results will allow to establish a better personalised medicine for HIV infected individuals.
This is a pilot study. We will treat 10 HIV-infected adults (1/2 with lipoatrophy) with GH depot for one year. Results will be compared to data from 10 HIV patients (1/2 with lipoatrophy), treated with Nutropin AQ subcutaneously. The primary endpoint of the study is to determine the effect of GH depot on body weight and lean tissue mass (LTM). The secondary endpoints are to document changes in: 1) whole body protein turnover (WBPT), 2) gluconeogenesis, 3) bone mineral density and markers of bone turnover, 4) fat distribution (lipoatrophy), 5) thymus size, 6) T-cell subsets, and 7) TNF-µ levels. Adverse events, such as glucose intolerance and edema, will be monitored at every visit.
The purpose of this trial is to determine whether using the diaphragm and a lubricant get can reduce women's risk of acquiring an HIV infection.
The purpose of this study is to determine whether a simplified lopinavir/ritonavir-based therapy will continue to keep the viral load at very low levels after initial treatment with a combination of Kaletra (lopinavir/ritonavir) plus tenofovir and emtricitabine.
