Abdominal tuberculosis in patients infected with the human immunodeficiency virus.

We compared the presentation of abdominal tuberculosis in 43 patients infected with the human immunodeficiency virus (HIV) and in 35 patients without HIV infection. Fever, weight loss, and extraabdominal lymphadenopathy were more common in HIV-infected patients, whereas ascites and jaundice were more frequent in patients without HIV infection. Intraabdominal lymphadenopathy and visceral lesions, visualized on computed tomography scans, were more common in HIV-infected patients, whereas ascites and omental thickening were more frequent in patients without HIV infection. Aspirates of abdominal lymph nodes were the only samples revealing acid-fast bacilli in eight HIV-infected patients, yielding a rapid diagnosis. Disseminated tuberculosis was present in 93% of the HIV-infected patients, compared with 31% of those without HIV infection; tuberculosis contributed to death in 23% of HIV-infected patients and in 31% of those without HIV infection. We conclude that abdominal tuberculosis in HIV-infected patients is almost invariably a manifestation of disseminated disease and results in significant mortality.
