    Abstract:
    In 28 patients with sarcoidosis patients (14 F, 14 M aged 19-54) lymphocytes subpopulations were estimated in double BAL from two lung segments: with the most (s.A) and with the least (s.B.) extensive involvement estimated by high resolution computed tomography (HRCT). HRCT score for whole lung correlated negatively with DCO (r = 0.46, p < 0.05), D/VA (r = -0.46 p < 0.05), Cstat (r = -0.57, p < 0.05) and Cdyn (r = 0.-057, p < 0.01). HRCT-score for lung segments A and B did not correlate with BAL-cell count and lymphocytes subsets from these segments. The relationship between percentage of lymphocytes HLA-DR in BAL from s.A and d(A-a)O2 (r = 0.38, p < 0.05) and the relationship between absolute number of CD25 in BAL from s.A and DCO (r = -0.38, p < 0.05) were observed. The percentage of lymphocytes in BAL from s.B correlated negatively with D/VA (r = -0.40, p < 0.05) and the percentage of HLA-DR lymphocytes in BAL from s.B. correlated negatively with Cdyn (r = -0.45, p < 0.05). Our results suggests usefulness of HRCT in estimation of sarcoidosis advancement but not in it's activity and indicate the careful interpretation the relationships between BAL results from only one lung segment and pulmonary function parameters.
