Abstract
Tuberculosis and HIV have combined to present a major threat to global public health. Each disease has a negative effect on the other, and mortality in patients with both tuberculosis and HIV is higher than that caused by either condition alone. In regions such as sub-Saharan Africa, as many as a third or more of all patients with tuberculosis have concomitant HIV infection. In urban centers in developed nations, HIV co-infection may also be quite common. Treatment of latent tuberculosis infection in persons with HIV is successful in preventing many cases of active disease, and newer ultra-short course regimens, such as those consisting of 2 months of rifampin and pyrazinamide, should aid in this effort. Diagnosis and treatment of active tuberculosis in HIV-infected patients may be difficult. Although treatment of active tuberculosis is generally successful in patients with HIV, drug interactions between anti-tuberculosis medications and antiretrovirals often complicate the matter, and expert guidance should be sought for proper management.
