Radiology of pulmonary turberculosis and human immunodeficiency virus infection in Gulu, Uganda.
Pulmonary tuberculosis is a major complication of human immunodeficiency virus (HIV) infection. The radiographic manifestations of pulmonary tuberculosis in HIV-infected patients are not typical of those seen in immunologically normal individuals. We sought to determine whether these manifestations provide clues to the pathogenesis of tuberculosis in HIV-infected persons. The radiographic manifestations of pulmonary tuberculosis were reviewed and classified in 82 HIV-positive and 53 HIV-negative tuberculous patients in Gulu, Uganda. Pulmonary presentations of tuberculosis were more acute in HIV-positive patients, and often included hilar or mediastinal adenopathy and pleural effusions, findings typical of primary tuberculosis in immunologically normal individuals. Many patients also had chronic forms of tuberculosis, either alone or in combination with acute disease. The findings of this study support the hypothesis that reactivation of latent infections and progression of pre-existent chronic disease produce a substantial portion of the tuberculosis burden of HIV-positive persons in Uganda. Tuberculosis control efforts should extend beyond efforts at decreasing transmission of new infections.
