[Tuberculosis in patients with human immunodeficiency virus infection].

Six men (mean age: 36.3 +/- 29 years) infected with the human immunodeficiency virus (HIV), four Japanese and two from Myammar, were admitted to our hospital for treatment of tuberculosis. In five, HIV positivity on serologic testing was first found when tuberculosis was diagnosed. The mean CD4 cell count was 37.3 +/- 29.6/microliters. Results of tuberculin skin tests were negative in 5 patients. One patient had pulmonary tuberculosis and 5 had miliary tuberculosis. Hilar and mediastinal lymphadenopathy was found on chest X-ray films in 4 patients and superficial lymphadenopathy was found in all patients. All patients had positive mycobacterial cultures of sputum and 2 patients had positive tests for acid-fast bacilli on smears of lymph-node aspirates. In one patient with tuberculosis meningitis, a culture of cerebrospinal fluid for acid-fast bacilli was positive. Epithelioid cell granulomas were found in samples of lung, liver, and bone marrow from 4 patients. Mycobacterium tuberculosis was isolated from all patients, and was not resistant to isoniazid, rifampicin, ethambutol, or streptomycin. Therefore all patients responded well to treatment of tuberculosis.
