Objective: To determine the extent of and reasons for relapse and re-infection in incident cases of tuberculosis (TB) in Human Immunodeficiency Virus (HIV)-infected patients on Highly Active Antiretroviral Therapy (HAART)\n2. Design: A prospective cohort study of patients with HIV previously treated for pulmonary TB and initiated on HAART in the SAPIT (Starting AIDS treatment at three Points in TB treatment) and START (Starting Tuberculosis and Anti-Retroviral Therapy) trials. Each incident case of TB recurrence in this cohort of adult patients on HAART will be investigated to assess whether the infecting mycobacterium is similar to that from the previous infection and whether the immune responses differ in cases of relapse and re-infection.\n3. Population: Men and women 18 years of age with documented HIV infection and past TB therapy as part of the SAPIT and START trial will be enrolled.\n4. Study Procedures: This study will involve 3 years of follow-up of patients who had been initiated on a course of TB therapy as part of the SAPIT and START trials. Upon exit from the SAPIT trial (i.e. 18 months post-TB diagnosis), study patients will be consented and enrolled in this cohort study. Study participants will be seen monthly for the first 3 months and thereafter 3 monthly, for routine clinic visits and ART services. At every visit patients will be screened for TB recurrence clinically, with chest radiograph and, whenever possible, with available TB diagnostics or new diagnostics that are being developed and/or tested.\n5. Study Outcome The primary endpoint of this study will be the development of recurrent TB. TB recurrence as a result of relapse will be defined as isolates of M. tuberculosis from the first and second episodes of TB which cluster in Restriction Fragment Length Polymerization (RFLP) analysis. TB recurrence as a result of re-infection will be defined as isolates from the first and second episode of TB which differ on RFLP analysis. Each study participant who has recurrent TB will be assessed by Interferon (IFN) gamma ELISPOT assay to compare cytotoxic lymphocyte (CTL)immune responses in TB relapse and re-infection.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'samplingMethod': 'NON_PROBABILITY_SAMPLE', 'studyPopulation': 'Men and women \\> 18 years of age with documented HIV infection and past TB therapy as part of the SAPIT and START trial will be enrolled.', 'healthyVolunteers': True, 'eligibilityCriteria': 'Inclusion Criteria:\n\n1.
