Abstract [en]

It has been suggested that a high level of hyaluronan (hyaluronic acid, HYA) in pleural fluid is an indicator of malignant mesothelioma. In 78 consecutive patients with pleural effusion of various causes the HYA concentration was measured in pleural fluid samples and in serum. Nine patients had malignant pleural mesothelioma, and in three of them the HYA level in pleural fluid was 100 mg/l or more. In 42 patients with effusions due to metastatic malignancy, the mean HYA in the pleural fluid was 75 mg/l, and in five the HYA level was above 100 mg/l. Cardiac insufficiency caused the effusion in 11 patients, of whom two had a level above 100 mg/l in pleural fluid. Four patients had a serologically confirmed viral infection and had HYA levels in pleural fluid of 8, 157, 335, and 554 mg/l, respectively. One patient had postinfectious effusion with an HYA level in pleural exudate of 748 mg/l, the highest in this investigation. Two patients had benign asbestos pleural effusions, and both had high pleural HYA levels (256 and 490 mg/l, respectively). The serum HYA values were much lower than in the pleural fluid, namely from 15 to 480 micrograms/l; the levels were independent of the levels in the pleural fluid. Thus, a high level of HYA in pleural fluid is not specific for mesothelioma but can occur in other malignant or benign diseases, and a low level does not exclude mesothelioma.
