Start TB Patients on ART and Retain on Treatment (START Study) — START  

HIV Clinical Trial

Official title: Start TB Patients on ART and Retain on Treatment: Combination Intervention Package to Enhance Antiretroviral Therapy Uptake and Retention During TB Treatment in Lesotho

Status Completed

Clinical Trial Summary

The purpose of the START Study is to identify an effective, cost-effective, acceptable intervention that addresses programmatic, structural and psychosocial barriers to ART initiation and retention during TB treatment, with the ultimate goal of improving health outcomes among HIV-infected TB patients in Lesotho. The study is a two-arm cluster randomized trial, randomized at the TB/HIV clinic level, which includes twelve TB/HIV clinics in Berea district. Clinics are randomized to deliver the combination intervention package (CIP) or standard of care (SOC), with stratification by facility type. The experimental intervention will be delivered to all HIV-infected TB patients in TB/HIV clinics randomly assigned to CIP. In TB/HIV clinics assigned to SOC, usual care procedures for ART initiation and retention will be delivered. Study hypotheses focus on the effectiveness of the CIP on HIV- and TB-related outcomes. Compared to HIV-infected TB patients attending SOC clinics, HIV-infected TB patients at CIP clinics will have superior HIV- and TB-related outcomes, including: - Greater ART initiation during TB treatment - Shorter time to ART initiation - Greater retention in ART care - Higher adherence to ART - Greater change in CD4+ count - Greater TB treatment success (completion and cure) - Greater sputum smear conversion - Higher adherence to TB treatment Additionally, CIP delivery will have an incremental cost-effectiveness ratio more favorable than alternative resource uses.

Clinical Trial Description

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. Lesotho, a small, landlocked country completely surrounded by South Africa, is among the world's poorest nations with one of the world's most severe epidemics of HIV and tuberculosis (TB). There is strong evidence that TB patients who are also infected with HIV have better survival rates if they begin antiretroviral therapy (ART) soon after starting TB treatment; however, there are many patients who do not initiate ART within the recommended timeframe, and who do not remain in care. ;
