Filter by:While HIV mainly infects mature T-cells it can also infect newly produced (or naïve) T-cells. These infected naïve T cells may then act a viral reservoir even in patients with undetectable viral loads. Understanding when and how these cells are infected is important because it could help us to understand why patients fail therapy even if they have a persistently undetectable viral load.
The purpose of this study is to assess the impact of prospective drug level monitoring and dose-adjustment of nelfinavir (NFV) on the clinical and virologic outcomes in a group of HIV-infected patients who have achieved virologic success while receiving a nelfinavir containing highly active antiretroviral therapy (HAART) regimen.
This pilot study will investigate the safety and effect of etanercept in HIV infection by studying HIV replication and immune function (as measured by CD4 counts) in individuals with HIV infection.
It is known successful HIV therapy depends on the patients' ability to take their medicine regularly. This study is designed to find out if an intervention designed to help patients remember to take their medication is effective. The intervention consists of a wristwatch that has an alarm to remind patients when to take their medication, a pillbox and three monthly phone calls by a physician. All these experimental measures are meant to improve the ability of patients to take their medicines.
This study will evaluate the effectiveness of a combination of clinic- and community-based voluntary counseling and testing programs in preventing HIV in African and Thai communities.
Lactic acidosis is a potentially life-threatening disease associated with the treatment of chronic HIV infection. Although acidosis is rare, hyperlactatemia is common and may have long term consequences yet to be recognized. Lactic acidosis is a manifestation of mitochondrial toxicity; consequences which have yet to be fully recognized and understood. In this study, we propose to look at lactate clearance and production by two methods, in four treatment groups, including HIV positive subjects on highly active antiretroviral therapy (HAART) treatment regimes and without HAART regimes, with liver steatosis and without, and compared with HIV negative controls. Supplementation with cofactors thiamine, niacin and L-carnitine, which may have a positive effect on lactate metabolism by facilitating mitochondrial function, will be studied as well.
The purpose of this R01 study is to evaluate the association between neuropsychological executive dysfunction and HIV infection among young injection and non-injection drug users. A longitudinal study will be conducted in which the cohort of seronegative drug users completing a baseline neuropsychological battery are re-assessed on three subsequent occasions, roughly six months apart. The primary aim of the longitudinal study is to estimate the magnitude of the suspected causal relationship between executive dysfunction and HIV-risk behaviors while adjusting for time-invariant (e.g. sex, ethnicity) and time-varying (e.g. degree of drug abuse) covariates. We also seek to evaluate: (1) the degree to which specific executive dysfunctions predispose heroin and cocaine users to high-risk injection practices or sex behaviors, and (2) whether observed relationship between executive dysfunction and HIV-risk behaviors can be understood independent of levels of drug -taking frequency, or whether the observed data are more consistent with complex patterns of interdependency between executive dysfunction, drug-taking frequency, and HIV-risk-behaviors. If successful, this project will shed new light on significant and potentially malleable HIV-risk factors in injection and non-injection drug users. This will be important evidence because injection drug abuse continues to account for a large proportion of HIV seroconversions particularly among young women and minorities. As such, this RO1 research project serves as an important initial step in a line of innovative investigations about suspected causal associations between neuropsychological deficits and HIV-risk behaviors in drug users. Ultimately, this line of investigation should lead to changes in public and clinical practices designed to prevent HIV infection.
This study tested the hypothesis that multivitamin supplementation given to HIV+ pregnant women in Tanzania would slow disease progression and enhance their overall health.
The purpose of this study is to examine the effects of multivitamin (B, C, E) supplementation on reducing the risk of morbidity and mortality outcomes among children born to HIV positive mothers, compared to placebo supplementation.
The purpose of this study is to learn about lower respiratory tract and bloodstream diseases among infants born to HIV positive mothers in Botswana. Study factors include how commonly infants get these diseases, the causes, and outcomes. The study will also try to measure the protective effect, if any, of breast feeding on respiratory disease illness and deaths.
