Among people living with HIV (PLWH), tuberculosis (TB) is the most common opportunistic illness and a leading cause of death, accounting for nearly a quarter of HIV-related deaths worldwide. Initiating antiretroviral therapy (ART) early during TB treatment significantly increases survival, and World Health Organization (WHO) guidelines recommend ART initiation for all PLWH as soon as possible after TB treatment initiation, regardless of CD4+ count. Yet in the African Region, only 42% of TB patients known to be living with HIV were on ART in 2010, and retention in ART programs has been limited. In Lesotho, only 27% of HIVinfected TB patients received ART in 2010. There is an urgent need to identify programmatic interventions that increase the proportion of HIV-infected TB patients on ART, shorten the duration between TB diagnosis and ART initiation, and improve adherence to medications and retention in care amongst HIV-infected TB patients in Lesotho.
