title: [Data on the etiology of the liquid of broncho-alveolar lavage in mediastino-pulmonary sarcoidosis (author's transl)].
abstract: The cell population of the liquid of broncho-alveolar lavage of 44 cases of mediastino-pulmonary sarcoidosis was compared to that of 12 normal controls, of 14 controls with a localized pulmonary affection, who underwent lavage in healthy contro-lateral segment, and of 33 patients with various diffuse interstitial pneumopathies, except hypersensitivity ones. In sarcoidosis, the total number of cells is significantly higher than in controls; such is the case for neutrophils. It is also higher for lymphocytes in sarcoidosis: 21.8, than in controls: 7.8, or in patients with other diffuse interstitial pneumopathies: 10.3. It is independent of the disease radiological stage, but closely related to its degree of activity; it showed important variations, going from 3 to 50%. The observation of a normal level of lymphocytes is not enough to exclude the diagnosis of sarcoidosis.
