    Abstract:
    In 20 patients with pulmonary sarcoidosis bronchoalveolar lavage (BAL) was performed. The cellular content was analysed and lymphocyte subpopulation was determined using monoclonal antibodies. The patients with more than 28% of BAL T lymphocytes are classified as patients with high intensity alveolitis (n = 8) and those with less than 28% of T lymphocytes as low intensity alveolitis (n = 12). Of the total number of BAL T lymphocytes in high intensity alveolitis CD 3+ T cells were 88.8 +/- 8.4% and in low intensity alveolitis 68.2 +/- 13.8% (p < 0.001). In high intensity alveolitis the number of CD 4+ T cells was increased and the number of CD 8+ T cells was decreased which caused the increased index CD 4:CD 8; 9.8 +/- 8.7. In low intensity alveolitis this ratio was 2.2 +/- 1.2. Effects of smoking were also analysed. In smokers the total number of BAL cells was higher 184.0 +/- 47.2 x 10(4) ml of BAL, and in nonsmokers 101.3 +/- 65.1 x 10(4) ml of BAL (p < 0.001). Smoking has no effects on the characteristics of the cellular elements and subpopulation of BAL lymphocytes in patients with sarcoidosis. In 7 patients T lymphocyte subpopulation in the peripheral blood were determined too. Patients with high intensity alveolitis had the increased index CD 4:CD 8 in the peripheral blood compared with low intensity alveolitis.
