An Evaluation of Selected Populations for HIV-1 Vaccine Cohort Development in Nigeria.

Development of a globally effective HIV-1 vaccine will need to encompass Nigeria, one of the hardest hit areas, with an estimated 3.2 million people living with HIV. This cross-sectional Institutional Review Board (IRB) approved study was conducted in 2009-12 at four market sites and two highway settlements sites in Nigeria to identify and characterize populations at high risk for HIV; engage support of local stakeholders; and assess the level of interest in future vaccine studies.

Effectiveness of highly-active antiretroviral therapy by race/ethnicity.

Objective: To determine the effectiveness of HAART by race/ethnicity.

Design: Prospective multicenter cohort study.

Methods: We studied 991 African-Americans and 911 European-Americans enrolled in the United States Military's Tri-Service AIDS Clinical Consortium Natural History Study who had dates of HIV seroconversion known within 5 years and followed between 1990 and 2002.

Long-term efficacy of routine access to antiretroviral-resistance testing in HIV type 1-infected patients: results of the clinical efficacy of resistance testing trial.

The long-term efficacy of making resistance testing routinely available to clinicians has not been established. We conducted a clinical trial at 6 US military hospitals in which volunteers infected with human immunodeficiency virus type-1 were randomized to have routine access to phenotype resistance testing (PT arm), access to genotype resistance testing (GT arm), or no access to either test (VB arm). The primary outcome measure was time to persistent treatment failure despite change(s) in antiretroviral therapy (ART) regimen.
