Filter by: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.
The purpose of this study is to examine effects of daily administration of multivitamin supplements at doses resembling the Recommended Dietary Allowance (RDA) during pregnancy to HIV positive women decreases the risks of low birth weight (<2500 g), and pre-term birth (< 37 weeks gestation), compared to multivitamin supplements at doses above the RDA.
The goals of this study are to: 1. determine the diarrheal rates, morbidity, mortality, and pathogens present among breast-fed infants born to HIV-infected mothers. - analysis by HIV status of infants, method of feeding, HIV viral loads / CD4 counts of infected mothers. - comparison to rates among infants born to HIV uninfected mothers. 2. link analysis of the functional quality of immunoglobulins in the breast milk of HIV-infected and uninfected mothers.
The purpose of this study is to find the most effective and safe treatment to prevent the passage of HIV from an infected mother to her baby.
The purpose of this study is to determine whether the oral administration of daily selenium supplements to HIV-1 positive pregnant women: enhances immune status and reduces the HIV-1 viral load at six months postpartum, reduces the risk of lower genital shedding of HIV-1 infected cells at 36 weeks of gestation, and reduces the risk of mastitis at six weeks postpartum, compared to placebo.
HIV infected patients are treated with highly active antiretroviral therapy (HAART). Side effects and the great number of pills reduces adherence to the treatment, and induces therapeutic failure. In order to maintain efficacy of HAART, new combination is evaluated. The aim of the study is to compare the antiviral efficacy of this salvage therapy combining lopinavir and amprenavir with 200 mg/d or 400 mg/d ritonavir, together with nucleoside reverse transcriptase inhibitors, over a 26-week period in HIV-infected patients in whom multiple antiretroviral regimens had failed.
The combination of two nucleoside analogues and one protease inhibitor is a highly active antiretroviral therapy (HAART) in HIV infected adults. In those with an undetectable viral load, a once daily combination of FTC, ddI, efavirenz would be easier to take, with less side effects and the same efficacy. The aim of the study was to evaluate if the once daily combination presents the same efficacy than the HAART therapy with less side effects and a better adherence.
