Brief Summary:
A significant number of HIV infected patients in Africa also have disseminated tuberculosis infection throughout multiple organs This type of tuberculosis is a significant cause of mortality in these patients The purpose of this study is to evaluate the safety and effectiveness of a vaccine designed to prevent disseminated tuberculosis
Detailed Description:
Disseminated infection with Mycobacterium tuberculosis dMTB has been documented in 10 to 25 of patients with HIV infection in Africa Unlike pulmonary tuberculosis pMTB most cases of dMTB are not recognized and death ensues rapidly Therefore dMTB may be a more important cause of HIV-associated mortality than pMTB in developing countries Mycobacterium vaccae MV is an investigational vaccine prepared by heat inactivation of a nontuberculous mycobacteria MV immunization may reduce the risk of HIV-associated dMTB The purpose of this study is to define risk factors for HIV-associated dMTB and to assess the safety and effectiveness of an MV vaccine for the prevention of HIV-associated pulmonary and disseminated tuberculosis
HIV positive patients with prior BCG immunization and HIV negative controls will be entered in a 5-year study in Tanzania Participants will be randomized to receive a 5-dose series of MV or placebo over 12 months with a repeat skin test at Month 14 Baseline evaluation will include medical history chest x-ray skin tests with purified protein derivative PPD and blood tests to evaluate interferon-gamma production Participants with PPD reactions greater than or equal to 5 mm will receive 6 months of prophylaxis with isoniazid Participants will be followed every 3 months for 3 to 5 years to assess new pMTB microbiologic or clinical diagnosis or dMTB microbiologic diagnosis Potential risk factors for dMTB will also be assessed
