Filter by:The aim of this study is to assess the efficacy of lopinavir/r in monotherapy and peg-interferon plus ribavirin for the control of both HIV and HCV infection respectively after 12 months of active treatment for HCV.
An estimated 3 million HIV-infected individuals will enter programs for antiretroviral (ARV) treatment in the coming year, with projected rates of requirement for ARV therapy extending to more than 10 million in sub-Saharan Africa, southeastern Asia, and Latin America in the coming decade. In these settings, Tuberculosis (TB) is an endemic infection in the population, and an estimated 30-60% of adults have been infected with TB, the leading opportunistic infection associated with HIV infection. The purpose of this study is to construct a standardized diagnostic evaluation (SDE) for TB that provides an increase in identification of participants with active pulmonary TB, without sacrificing specificity.
The purpose of this study is to determine the safety and efficacy of a VRC DNA/rAd5 vaccine regimen in healthy, circumcised men and male-to-female (MTF) transgender persons who have sex with men. NOTES: As of April 2013, all vaccinations in this study have been stopped. As of June 2017, this study has been closed.
The aim of this study is to measure the prevention of lipoatrophy in patients treated with Lopinavir/R in monotherapy versus ZDV + 3TC + ABC
The aim of this study is to evaluate the efficacy for the recovery of peripheral fat of lopinavir/ritonavir in monotherapy versus abacavir/lamivudine and lopinavir/ritonavir in subjects who developed lipoatrophy while receiving zidovudine plus lamivudine plus abacavir.
People infected with HIV have a greater risk of developing cardiovascular disease than people not infected with HIV. This may be due to increased inflammation in the blood vessels. This study will determine whether an anti-inflammatory drug, pentoxifylline, in combination with antiretroviral medications, is more effective at improving blood vessel function and reducing inflammation than antiretroviral medications alone in people infected with HIV.
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.
Neuropathy results from damage to the nerves in the feet and legs. It is usually experienced as pain, tingling or numbness. In HIV-infected people, neuropathy can result from the infection itself or be a side effect of antiretroviral treatment. The purpose of this study is to determine whether two different drugs, methadone and duloxetine, reduce neuropathy-associated pain in HIV-infected people. This study will also examine whether utilization of both of these drugs is more effective than treatment with only one.
This study is a multicentre, randomized, placebo-controlled, fully blinded, clinical trial of twice daily oral valacyclovir 500mg versus placebo with the goal of delaying the need for initiating HAART among HIV infected individuals who neither use nor require HAART, and who have not used chronic suppressive anti-HSV therapy for at least the 6 months prior to study initiation.
The purpose of this randomized pilot study was to conduct an intervention with 68 rural women living with AIDS to compare the effectiveness of two different programs on compliance with HIV/AIDS treatment regimens, improvement in knowledge about HIV/AIDS and TB, improvement in psychological distress, reduction in stigma; satisfaction with care provided to family members, reduction in number of opportunistic infections, increase in CD4 levels and completion of the designed Asha-Life (AL) program. The trial was designed to assess the impact of the Asha-Life (AL) intervention engaging with an HIV-trained village woman, Asha (Accredited Social Health Activist), to participate in the care of women living with AIDS (WLA), along with other health care providers compared to a Usual Care group. Two high prevalence HIV/AIDS villages in rural Andhra Pradesh, which were demographically alike and served by distinct Public Health Centers, were selected randomly from a total of 16 villages.
