Human Leucocyte Antigen Supertypes And Immune Susceptibility To Hiv-1, Implications
(University of Nairobi, 2001-11-01)
A randomized, placebo-controlled trial of monthly azithromycin prophylaxis to prevent sexually transmitted infections and HIV-1 in Kenyan sex workers: study design and baseline findings
Our objectives were to describe the baseline findings of a trial of antibiotic prophylaxis to prevent sexually transmitted infections (STIs) and HIV-1 in a cohort of Nairobi female sex workers (FSWs). A questionnaire was ...
Resistance to HIV-1 infection among persistently seronegative prostitutes in Nairobi, Kenya
BACKGROUND: There is indirect evidence that HIV-1 exposure does not inevitably lead to persistent infection. Heterogeneity in susceptibility to infection could be due to protective immunity. The objective of this study ...
HIV-1-specific mucosal IgA in a cohort of HIV-1-resistant Kenyan sex workers
Objectives: Most HIV-1 transmission is sexual; therefore, immune responses in the genital mucosa may be important in mediating protection against HIV infection. This study examined HIV-1-specific mucosal IgA in a cohort ...
Acute sexually transmitted infections increase human immunodeficiency virus type 1 plasma viremia, increase plasma type 2 cytokines, and decrease CD4 cell counts
In Kenya, the median incubation time to AIDS in seroconverting sex workers is 4 years; this incubation time is specific to female sex workers.We studied the influence of acute sexually transmitted infections (STIs) on ...
Associations of sexual risk taking among Kenyan female sex workers after enrollment in an HIV-1 prevention trial.
BACKGROUND: Female sex workers (FSWs) often lack the ability to negotiate safer sex and are at high risk for HIV-1 infection and sexually transmitted infections (STIs). METHODS: Seronegative FSWs were enrolled in an ...
Coinfection with herpes simplex virus type 2 is associated with reduced HIV-specific T cell responses and systemic immune activation.
(University of Nairobi,, 2008)
BACKGROUND: Chronic coinfection with herpes simplex virus type 2 (HSV-2) and human immunodeficiency virus (HIV) has been associated with an increased HIV viral load and more rapid disease progression, perhaps related to ...
Cytotoxic T cell responses to multiple conserved HIV epitopes in HIV-resistant prostitutes in Nairobi.
(University of Nairobi, 1998-11)
Many people who remain persistently seronegative despite frequent HIV exposure have HIV-specific immune responses. The study of these may provide information about mechanisms of natural protective immunity to HIV-1. We ...
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
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 ...
