    Abstract:
    The aim of this prospective study was to investigate the main features of standard chest X-ray in patients with concomitant tuberculosis and HIV infection. From 21 December 1992 to 21 February 1993, we compared 45 chest X-rays of HIV+patients with pulmonary tuberculosis with those of 73 HIV negative patients with pulmonary tuberculosis. Our results revealed that extrapulmonary thoracic localizations were remarkably frequent in HIV+tuberculosis patients (57.8% versus 22% in HIV-patients; P < 0.05). Extrapulmonary localizations were frequently mediastinal lymph nodes (82.7%). Parenchymal involvement was often extensive including frequent miliary images (20% versus 38.3% in HIV-patients). Thus despite the lack of CD4 counts in our study, we were able to observe that about one half the co-infected tuberculosis patients had reached the stage of AIDS as defined by the CDC in 1987. These findings are in agreement with those reported in the literature and would suggest that thoracic manifestations of tuberculosis is a good marker of the state of immunodepression. In the Ivory Coast, pneumologists examined 188 chest X-rays of patients with pulmonary tuberculosis (TB) treated at the Treichville Antituberculosis Center to compare the principal X-ray characteristics of patients with only TB with those of patients infected with TB and HIV. They did not conduct CD4 counts. 45 TB patients were also infected with HIV for an HIV prevalence rate of 38%. 73.3% of HIV infected TB patients were infected with HIV-1. 4.4% were infected with HIV-2. 22.3% were infected with both HIV-1 and HIV-2. Men predominated in both the TB only group and the TB-HIV group (67.1% and 77.7%, respectively). HIV infected patients were more likely to have thoracic extrapulmonary TB lesions than HIV seronegative patients (57.8% vs. 22%; P 0.05). Thus, 57.8% of co-infected patients had AIDS as defined by the CDC in 1987. Among co-infected patients, lesions on the mediastinal lymph nodes predominated (80.7%). Involvement of the parenchyma, demonstrated by miliary X-rays, was rather common (22.3% vs. 38.3% for HIV negative patients). The X-ray of 84.6% of patients with caseous pneumonia were infected with HIV and TB. These findings parallel those in the literature. They suggest that thoracic manifestations of TB indicate the state of immunodepression.
