Limited additive value of pleural fluid carcinoembryonic antigen level in malignant pleural effusion.

Objective: To assess the additive value of pleural fluid carcinoembryonic antigen (CEA.PF) level in the diagnosis of malignant pleural effusion.

Methods: Thoracentesis and closed pleural biopsy were performed in consecutive patients with pleural effusions.

Diagnostic value of pleural fluid adenosine deaminase in tuberculous pleuritis with reference to HIV coinfection and a Bayesian analysis.

Objectives: To evaluate the diagnostic use of pleural fluid adenosine deaminase (ADAPF) levels in tuberculous pleuritis (TBpl), with a special reference to HIV coinfection and a Bayesian analysis.

Methods: We investigated a total of 216 patients with pleural effusion, including 100 with TBpl, 68 with malignant effusion, 6 with transudates, 19 with empyema, 15 with miscellaneous diseases, and 8 with diseases of unknown etiology.

Results: The mean values (SE) of ADAPF were 110 (4.
