A COMPARATIVE STUDY OF CHEST RADIOGRAPHIC FEATURES BETWEEN HIV SEROPOSITIVE AND HIV SERONEGATIVE PATIENTS OF PULMONARY TUBERCULOSIS.

Chest radiographic appearance of pulmonary tuberculosis (TB) in Human Immunodeficiency Virus (HIV) positive patients was reviewed. A study group of 50 HIV +ve cases and a control group of 100 HIV -ve cases were analysed. The chest radiographs of HIV seropositive group showed significantly higher incidence of thoracic lymphadenopathy (36% vs 8%, P<.001), pleural effusion (28% vs 10%, P<.01) and miliary pattern (12% vs 2%, P<.05) as compared to the seronegative group. Cavitation was less common in the seropositive group (8% vs 35%, P<.001) than the seronegative group. Upper zone involvement was significantly less common in the study group (38% vs 77%, P<.001) as compared to the control group.
