摘要：Background: Pulmonary tuberculosis is still the most common form of tuberculosis in HIV infected patients having different presentations according to the degree of immunosuppression. This study appraised the impact of HIV infection on clinical, laboratory and radiological presentations of tuberculosis. Methods: The clinical, laboratory and radiological presentations of pulmonary TB in 56 HIV-infected patients were compared with 56 individually sex and age matched HIV-seronegative ones, admitted to Imam Hospital in Tehran (1999–2006) using paired t -test in a case control study. Results: All cases and the controls were male. Fever was found in 83.9% of the HIV positive patients compared to 80% of the HIV negative ones. Cough was the most common clinical finding in the HIV negative group (89.3% vs. 82.1% in HIV positive group). Among radiological features, cavitary lesions, upper lobe and bilateral pulmonary involvement were observed significantly less often in the HIV-infected group. On the contrary, lymphadenopathy was just present in the HIV positive group in this series of patients (12%) and primary pattern tuberculosis was more common, as well (71% vs. 39%, P = 0.02). The Tuberculin test was reactive in 29% of the HIV/TB patients. Conclusion: The coexistence of both infections alters the picture of tuberculosis in many aspects and should be taken into account when considering a diagnosis of HIV infection and its potential for TB co-infection, and vice-versa.
