Oxygen radical formation of alveolar macrophages (by luminogenic substrate-intensified chemiluminescence) and the concentrations of phagocyte products myeloperoxidase, elastase and lactoferrin, as well as alpha-proteinase inhibitor and albumin were measured in bronchoalveolar lavage fluid of 28 patients with pulmonary sarcoidosis. There were 15 men and 13 women (mean age 41 [18-62] years), 10 of them with sarcoidosis I, 10 with clinically active sarcoidosis II and 8 with inactive sarcoidosis II. Six healthy persons served as controls. The purpose of the study was to demonstrate the extent of correlation between macrophage activity and stage of sarcoidosis. Patients in stage I had significantly higher luminescence (346 +/- 253 relative light units [RLU] per second) than the controls (117 +/- 29 RLU/s; P less than 0.02). But the difference between controls and patients in clinically active stage II (294 +/- 75 RLU/s) was not significant and the luminescence in patients with clinically inactive stage II was within normal range (119 +/- 33 RLU/s). The concentrations of proteins measured in the lavage fluid was increased, independent of the site of formation. These data indicate that in pulmonary sarcoidosis there exists, early and independent of stage, a marked activation of alveolar macrophages with increased production of oxygen radicals and a resulting increase in permeability of the alveolo-capillary membrane.
