Tuberculosis and HIV infection: global perspectives.
This paper reviews the epidemiological and clinical aspects of the interaction between Mycobacterium tuberculosis and HIV infection. The incidence of HIV-associated tuberculosis is increasing worldwide and is expected to increase further, especially in Africa and parts of Asia. HIV infection appears to increase the likelihood that tuberculous infection will occur after tubercle bacilli are inhaled into the lungs. Moreover, there is persuasive evidence that in the presence of HIV infection, new-onset tuberculous infection will progress rapidly to clinically significant disease and the probability that latent tuberculous infection will reactivate is enormously increased. The accelerating and amplifying influence of HIV infection is also contributing to the increasing incidence of disease caused by multidrug-resistant strains of M. tuberculosis. Neither clinical nor radiographic features reliably distinguish the majority of patients with HIV-associated tuberculosis from those who are non-HIV-infected. Some HIV-infected patients, however, have atypical manifestations and are difficult to diagnose. Chemotherapy for 6 months with conventional antituberculosis drugs cures most patients, but many died during or after treatment of other AIDS-related complications. HIV is contributing heavily to the worldwide increase in tuberculosis. There is also mounting evidence that tuberculosis accelerates the course of co-existing HIV disease.
