Abstract

BAL and blood mononuclear cells and their reactivity to Kveim antigen, tuberculin and concanavalin A (Con A) were studied in nine patients with different clinical stages of sarcoidosis. After separation by plastic adherence, non-adherent cells (mainly lymphocytes) were admixed with 10% autologous adherent cells (monocytes/macrophages). After 3 and 6 days' culture with Kveim antigen (1, 10, 100 micrograms/ml), PPD tuberculin (2.5 micrograms/ml) and Con A (10, 20, 40 micrograms/ml) stimulation was measured as incorporation of 14C-thymidine into DNA. Except for occasional reactions the study did not show any unitary significant increase in lymphocyte response to the different concentrations of Kveim antigen in either BAL or blood. For Con A there was a weaker response by BAL-mononuclear cells with no difference between 3 and 6 days, compared with blood where there was an early peak. The lymphocyte reaction to PPD was weak with no difference between blood and BAL.
