Popis: | To investigate the mechanism of eosinophilia in patients with eosinophilic pleural effusions, we measured the activities of eosinophil colony-stimulating factor (Eo-CSF) and stimulating factor for eosinophil survival in the eosinophilic pleural fluids of six patients (two with tuberculous pleuritis, two with drug allergy, and one each with chronic eosinophilic pneumonia and pleuritis associated with rheumatoid arthritis). The number of eosinophil colonies formed by the pleural fluid of patients with eosinophilic pleural effusions significantly exceeded that of control patients with noneosinophilic pleural effusions (7.5 +/- 1.9 colonies/10(5) bone marrow cells, n = 6, versus 0.3 +/- 0.1 colonies/10(5) bone marrow cells, n = 6, P < 0.01). Similarly, eosinophil survival evaluated on day 4 of culture with pleural fluid of patients with eosinophilic pleural effusions significantly exceeded that of patients with noneosinophilic pleural effusions (83.9 +/- 9.8% versus 46.1 +/- 11.2%, P < 0.001). Both activities were inhibited mainly by anti-IL-5 antibody and partially by anti-GM-CSF antibody and anti-IL-3 antibody. Mononuclear cells obtained from eosinophilic pleural fluid released the activities of Eo-CSF and stimulating factor for eosinophil survival in vitro. These findings suggest that GM-CSF, IL-5, and IL-3 are important to eosinophil accumulation in pleural cavity as stimulators of proliferation and survival of eosinophils. |
