[Thoracic tuberculosis in adults. A comparative study of radiological findings of HIV seropositive and seronegative patients]. / Tuberculosis torácica en el adulto. Estudio comparativo de los hallazgos radiológicos entre enfermos VIH positivo y negativo.

ABSTRACT

We compare the radiologic manifestations of chest TB in three groups of patients HIV patients (52 cases), HIV negative patients (85 cases and 100 cases). Initial radiologic findings were similar in the two seronegative groups, even though there is an eight-year interval between both series. However, seropositive patients have a higher risk of acquiring the infection (x 2.25), of extrathoracic disease (x 4.22), of coincidental infections (p < 0.0002) and of progression of the disease p < 0.0003) than the normal population. Lymphadenopathy and miliary TB are much more common in the HIV positive patients (x 6.23 and x 44 respectively). Cavitation, pulmonary scarring, volume loss and calcification are more frequent among the seronegative patients (p < 0.03), as well as pleural disease (p < 0.0001).
