A study of 284 patients with tuberculous pleural effusions cytologically diagnosed by smears stained with giemsa common method allowed distinguishing two groups: typical and untypical patients. Typical tuberculous pleural effusions were characterized by the presence of lymphocytes, typical characterized by the presence of lymphocytes, typical Langhans and/or epithelioid cells, typical caseum and other products and a few number of neutrophils. Untypical tuberculous pleural effusions were marked by the preponderance of lymphocytes, the complete degeneration of neutrophil, the presence of macrophages, lipophages, untypical Langhans and epithelioid cells, and of minor but clear caseum and other degeneration elements, no common bacteria on smears. With these criteria, the true of cytodiagnosis in comparison with histophatology was 80%.

Tuberculous pleurisy is the most common form of extrapulmonary tuberculosis in Korea. Tuberculous pleurisy presents a diagnostic and therapeutic problem due to the limitations of traditional diagnostic tools. There have been many clinical research works during the past decade. Recent studies have provided new insight into the tuberculous pleurisy, which have a large impact on clinical practice. This review is a general overview of tuberculous pleurisy with a focus on recent findings on the diagnosis and management.

PURPOSE: To describe radiologic differences between tuberculous pleural effusion and empyema on the basis of computed tomography(CT). MATERIALS AND METHODS: We reviewed retrosepectively CT findings of 50 patients with pathologically and grossly proved empyema. Twenty-two patients had empyema, and 28 patients had tuberculous pleurisy. RESULTS: CT findings known to be useful in differentiating tuberculous pleural effusion from empyema (1) contour and extent of pleural thickening, (2) mediastinal pleural involvement, (3)accumulation of extrapleural tissue and (4) change of ipsilateral thoraic volume of empyema. However, none of the above findings were helpful in the differential diagnosis of empyema. CONCLUSION: The differentation of tubrculous pleurisy from pyogenic empyema may be not possible with CT findings only.

BACKGROUND: IFN-gamma is the main effector mediator of the host immune response against Mycobacterium tuberculosis. Evaluating the IFN-gamma gene expression in response to M. tuberculosis antigens may help in elucidating the host defense mechanism against M. tuberculosis and in the development of a vaccine. METHODS: The IFN-gamma mRNA expression in the lymphocytes obtained from pleural effusions from tuberculous pleurisy patients (TB-PLC) after in vitro stimulation with whole cell M. tuberculosis(H37Rv), purified protein derivatives(PPD), man-lipoarabinamman (man-LAM), ara-LAM and Antigen 85B(Ag85B) were evaluated. The degree of IFN-gamma mRNA expression was determined by a semiquantitative reverse transcriptase-polymerase chain reaction (RT-PCR) method. RESULTS: M. tuberculosis induced the expression of IFN-gamma mRNA in the TB-PLC in time and dose dependent manners. The PPD and Ag85B induced high levels of IFN-gamma mRNA expression in the TB-PLC. However, man-LAM inhibited IFN-gamma mRNA expression in the TB-PLC, while ara-LAM did not. CONCLUSION: IFN-gamma mRNA expression in TB-PLC is stimulated by PPD and Ag85B, but inhibited by man-LAM.

Polymerase chain reaction was used to detect DNA sequence belonging to IS 6110, specific agent for M.tuberculosis, directly in pleural fluids of 48 patients suspected to be due to tuberculosis and 13 patients suspected to be due to lung cancer selected by clinical, biochemical and cytological data. Excepted 2 samples showed to have inhibition factors to the activity of tag polymerase, 33 of 48 samples were found PCR positive, giving a sensitivity of 72%. All 13 pleural fluids taken from patients with pleural effusion due to cancer were PCR negative. The results: PCR of pleural fluid can be a useful method for rapid diagnosis of pleural effusion due to tuberculosis, which is difficult to differentiate with those due to cancer.
