Between July 2008 and November 2010, we enrolled heterosexual HIV-1 serodiscordant couples from 9 sites in Kenya and Uganda (Tables S1 and S2).15 (link) HIV-1 seronegative partners had normal renal function, were not infected with hepatitis B virus (HBV), and were not pregnant or breastfeeding. HIV-1 seropositive partners were not using antiretroviral therapy and did not meet Kenyan or Ugandan guidelines for initiation of antiretroviral therapy.
The study protocol was approved by the University of Washington Human Subjects Review Committee and ethics review committees at each of the study sites (Table S3). All participants provided written informed consent in English or their local language.
