Twenty-three patients with nonspecific pleuritis were studied to determine clinical outcome. After a mean follow-up period of 6 months (1 to 36 months), a diagnosis was reached in 17 patinets, while 6 patients remained unknown.The causes of the nonspecific pleuritis diagnosed on initial pleural biopsy were tuberculosis (11 patients, 48%), neoplasm (2 patients, 8.7%), parapneumonic effusion (1 patient), subphrenic abscess (1 patient), congestive heart failure (1 patients), and nephrotic syndrome (1 patient).The diagnosis was made by therapeutic trials (tuberculosis: 11 patients, parapneumonic effusion: 1 patient, congestive heart failure: 1 patient), by repeat pleural biopsy in 1 hepatoma, by open thoractomy in 1 lung cancer, by exploratory laparotomy in 1 subphrenic abscess, and by kidney biopsy in 1 nephrotic syndrome.The WBC counts (more than 2,000/mm3) and lymphocyte percentage (more than 60%) in the pleural fluid were significantly elevated in the patients with tuberculosis compared to those with malignant pleurisy, and other laboratory data were meaningless.As a result of this investigation, we suggest that tuberculous pleurisy is the most common cause of nonspecific pleuritis in Korea and that therapeutic trial with antituberculous medication for patients with high WBC count and lymphocyte percent in pleural fluid can help to locate the nonspecific pleuritis.
