We examined associations between maternal HLA and vertical HIV-1 transmission in a perinatal cohort of 277 HIV-infected women in Nairobi. HLA class I genes were amplified using sequence-specific oligonucleotide probes and ...

Data collected in the years 2001–2003 from an antenatal clinic in Nairobi, Kenya, were used to assess the benefit of couple counselling and test it as a way of increasing the uptake of interventions in the prevention of ...

Background High plasma HIV-1 RNA concentrations are associated with increased risk of HIV-1 transmission. Initiation of antiretroviral therapy (ART) reduces plasma HIV-1 concentrations, but little empiric data are available ...

Humoral immunity, and specifically immunoglobulin A (IgA) that is directed against human immunodeficiency virus (HIV)-1, may contribute to protection against HIV-1 acquisition at mucosal surfaces. HIV-1-specific IgA has ...

As prevention of mother-to-child HIV-1 transmission (PMTCT) programs decrease the numbers of HIV-1–infected infants, it remains important to improve growth in HIV-1–exposed, uninfected (EU) infants. To determine the growth ...

Background The incidence and correlates of breast milk HIV-1 RNA detection were determined in intensively sampled women receiving highly active antiretroviral therapy (HAART) for the prevention of mother-to-child HIV-1 ...

Background Current WHO guidelines recommend antiretroviral therapy (ART) initiation at CD4 counts ≤350 cells/µL. Increasing this threshold has been proposed, with a primary goal of reducing HIV-1 infectiousness. Because ...

Background Physiologic and behavioral changes during pregnancy may alter HIV-1 susceptibility and infectiousness. Prospective studies exploring pregnancy and HIV-1 acquisition risk in women have found inconsistent ...

Background HIV prevalence has recently declined in several African countries, and prior to this the risk of HIV acquisition per unprotected sex contact also declined in Kenyan sex workers. We hypothesized that heterogeneity ...

: To define the frequency and timing of breast milk transmission of HIV-1. DESIGN: Meta-analysis of data abstracted from published literature. SUBJECTS: Participants in prospective cohort studies of MTCT ...
