How important is the ‘quality’ of the cytotoxic T lymphocyte (CTL) response in protection against HIV infection?
(2001-11)
Cytotoxic T lymphocyte (CTL) responses have been associated with protection from HIV-1 infection in people with a high degree of exposure to HIV and who show no serological evidence of HIV infection (HEPS, highly exposed ...
Regional Differences in Prevalence of HIV-1 Discordance in Africa and Enrollment of HIV-1 Discordant Couples into an HIV-1 Prevention Trial
(2008)
Background
Most HIV-1 transmission in Africa occurs among HIV-1-discordant couples (one partner HIV-1 infected and one uninfected) who are unaware of their discordant HIV-1 serostatus. Given the high HIV-1 incidence ...
Rapid Decline in Risk of HIV-l Acquisition After Enrollment in a Vaccine Preparedness Cohort of Kenyan Prostitutes: Implications for the Design of HIV -1 Vaccine Efficacy Trials
(2002-02)
Background: In designing HIY-l vaccine efficacy trials, it will be important to accounrfor changes in HIY -1 incidence, especially changes over time and while participating in riskreduction programs.
Methods: Data from ...
Breast milk HIV-1 suppression and decreased transmission: a randomized trial comparing HIVNET012 nevirapine versus short-course zidovudine
(2005)
Objective: To compare the effect of perinatal regimens of short-course nevirapine
(HIVNET012)andzidovudine[Thai-CentersforDiseaseControlandPrevention(CDC)
regimen] on breast milk viral shedding and perinatal transmission ...
Hormonal contraception and HIV-1 disease progression among postpartum Kenyan women
(2007)
Objective
To assess the immediate and longer-term effects of the use of hormonal contraception on the progression of HIV-1 disease in postpartum women.
Design
A prospective cohort study.
Methods
Information on ...
New insights into HIV-1 specific cytotoxic T-lymphocyte responses in exposed, persistently seronegative Kenyan sex workers
(2001)
A clearer understanding of HIV-1 specific immune responses in highly-exposed, persistently seronegative (HEPS) subjects is important in developing models of HIV-1 protective immunity. HIV-1 specific cytotoxic T-lymphocytes ...
Highly Active Antiretroviral Therapy (HAART) versus Zidovudine/Nevirapine Effects on Early Breast Milk HIV-1 RNA: A Phase II Randomized Clinical Trial
(2008)
Background
Defining the effect of antiretroviral regimens on breast milk HIV-1 levels is useful to inform the rational design of strategies to decrease perinatal HIV-1 transmission.
Methods
Pregnant HIV-1 seropositive ...
Association of Levels of HIV-1–Infected Breast Milk Cells and Risk of Mother-to-Child Transmission
(2004)
Understanding how the level of human immunodeficiency virus type 1 (HIV-1)–infected breast milk cells (BMCs) affects HIV transmission via breast-feeding can shed light on the mechanism of infection and aid in establishing ...
HIV-1 neutralizing activity is correlated with increased levels of chemokines in saliva of HIV-1-exposed uninfected individuals.
(University of Nairobi,, 2008)
AIM:
Mucosal HIV-1 exposure stimulates a variety of mucosal immune responses, including IgA1-mediated virus neutralization, even in the absence of an established infection. We hypothesized that other immune molecules might ...
CCR5 Promoter Polymorphisms in a Kenyan Perinatal Human Immunodeficiency Virus Type 1 Cohort: Association with Increased 2-Year Maternal Mortality
(2001)
The CCR5 chemokine receptor acts as a coreceptor with CD4 to permit infection by primary macrophage-tropic human immunodeficiency virus type 1 (HIV-1) strains. The CCR5Δ32 mutation, which is associated with resistance to ...
