The objective of the study was to determine if residual pleural thickening after treatment for pleural tuberculosis could be predicted from the pleural fluid findings at the time of the initial thoracentesis. Forty-four patients initially diagnosed as having pleural tuberculosis between January 1986 and January 1988 were separated into two groups: the 23 patients in group 1 had residual pleural...

BACKGROUND Detection of pneumococcal antigen may help to increase the rate of diagnosis of pneumococcal pneumonia. This study was designed to determine the value of rapid detection of pneumococcal antigen in pleural fluid from patients with community acquired pneumonia. METHODS Thoracentesis was performed in patients suspected of having empyema and in patients with pneumonia of unknown aetiol...

  Background and Objectives:Infection of pleural fluid is a common disease and because of antibiotic administration, the microbiology of this fluid has changed. The aim of this study was to determine the common bacteria and suitable antibiotics for treatment in pleural effusion (PE). Materials and Methods: In this cross sectional study, 1210 samples with exudative features were cultured for p...

Clinical and immunologic evidence suggests that tuberculous pleuritis provides a model to understand protective immune mechanisms against Mycobacterium tuberculosis. We therefore evaluated the pattern of cytokine mRNA expression and cytokine production in pleural fluid and blood of patients with tuberculous pleuritis. RNA was extracted from mononuclear cells, reverse transcribed to cDNA, and am...

Some proand anti-inflammatory cytokines and angiogenesis-related factors play important roles in the inflammatory response after surgery. To study their kinetics and mutual relationships after major lung resection for lung cancer, concentrations of interleukin (IL)-6, -8 and -10 and vascular endothelial growth factor (VEGF) were measured in serum and pleural fluid. Venous blood and pleural flui...

To analyze the association of the eosinophil granulocyte with pleural effusions, we measured the concentrations of two eosinophil proteins, eosinophil cationic protein (ECP) and eosinophil protein X (EPX), in pleural fluid and serum of 92 patients with pleural effusions of various causes. We observed significantly higher ECP and EPX concentrations in eosinophilic than in noneosinophilic pleural...

BACKGROUND A high concentration of hyaluronic acid in pleural fluid is suggestive of malignant mesothelioma. However, a relatively high concentration of hyaluronic acid was also seen in the pleural fluid of patients with benign inflammatory diseases. To show the utility of measuring hyaluronic acid levels in pleural fluid to diagnose tuberculous pleurisy, we compared the clinical features and l...

We hypothesized that inhibition of matrix-degrading metalloproteinases (MMPs) accounts for a portion of the pleural fibrosis and adhesions of tetracycline pleurodesis. MMPs recently have been described in pleural fluid from patients with both exudative and transudative effusions. Since tetracyclines are recognized inhibitors of other metalloproteinases, we investigated their inhibitory capacity...

Continuous movement of fluid into and out of the pleural compartment occurs in normal chest physiology and in pathophysiological conditions associated with pleural effusions. RT-PCR screening and immunostaining revealed expression of water channel aquaporin-1 (AQP1) in microvascular endothelia near the visceral and parietal pleura and in mesothelial cells in visceral pleura. Comparative physiol...
