Abstract
In 49 patients with pulmonary sarcoidosis BAL differential and T-cell count, determination of IgG, IgA levels in BAL-fluid were performed. A significant increase of lymphocytes, T-cell count and levels of IgG in BAL-fluid in patients with active sarcoidosis was found. Steroid therapy significantly lowered lymphocyte counts and increased the number of macrophages.
