[Value of bronchoalveolar lavage in assessing the activity of sarcoidosis].

BAL was performed in different courses of sarcoidosis in order to evaluate the importance of this examination. We found a higher degree of lymphocytosis in Löfgren's syndrome and in relapses than in the others. Probably there is a direct connection between high intensity alveolitis and reduction of diffusing capacity. There could not be found any correlation to other markers of activity (lung function, SACE, 67-Gallium-Scan).
