Purpose

Tuberculosis (TB), a bacterial infection common in HIV infected people, is a major problem in developing countries. The purpose of this study is to test the effectiveness of a combined treatment strategy using directly observed therapy (DOT) for HIV infected patients with TB. Participants will be recruited from resource-poor communities in Durban, South Africa.

Primary Outcome Measures

  • Diagnosis of an AIDS-defining illness
  • 18-month mortality

Enrollment: 592
Study Start Date: August 2009

Detailed Description:

TB is the most common serious infectious complication associated with HIV in sub-Saharan Africa and is also the most common cause of death among HIV infected patients in developing countries. Furthermore, TB in an HIV infected person accelerates the progression of HIV disease and hastens death. This study will evaluate a combined TB and antiretroviral treatment (ART) strategy utilizing DOT in HIV infected people coinfected with TB. This study will compare two treatment strategies: TB and HIV medications given concurrently (integrated arm) and TB treatment completed first, followed by HIV treatment (sequential arm).
This study has two parts. The entire study will last 24 months after participants have been randomly assigned to one of two arms. Arm 1 (integrated arm) participants will receive didanosine (ddI), efavirenz (EFV), and lamivudine (3TC) once daily concurrent with standard TB therapy. ART and TB medications will be provided through DOT on weekdays; participants will take their medications without DOT on weekends. Arm 1 participants will also attend four 15- to 20-minute sessions of an adherence study program at study start, Week 2, Month 2, and 1 to 3 weeks prior to the end of TB therapy.
Arm 2 (sequential arm) participants will first receive DOT-provided TB treatment alone. After completion of TB treatment, participants will receive ddI, EFV, and 3TC once daily without DOT.
Study visits in the first part of the study will occur at screening, study start, Weeks 1, 2, and 3, and every month until the end of the first part of the study at Month 12. Study visits will include blood collection, medical and medication history assessment, a physical exam, and pill counts. Patients will be asked to complete an adherence questionnaire at every study visit and a sexual behavior survey and quality of life questionnaire at study start and Month
