focused on patients with MPE, TPE, and PPE. Further, the diagnostic criterion
for MPE was based on the presence of malignant cells in pleural effusion or
pleural biopsy specimens.7 (link) The inclusion criteria for
patients with TPE were chronic granulomas in the pleural tissue, clinical
response to anti-tuberculosis treatment, or acid-fast bacteria found in pleural
fluid or sputum. PPE was identified as exudative effusions associated with
bacterial pneumonia, lung abscesses, or bronchiectasis, absence of
Mycobacterium tuberculosis (MTB) in the pleural fluid,
pathological manifestations of inflammatory pleuritis, pleural fibrosis and
plaques, or chronic empyema without evidence of MTB and good response to
antibiotic therapy.26 (link) Demographic and baseline characteristics including age,
sex, and color of the pleural fluid were collected from all study
participants.
