چکیده
between the progression of the disease and SACE activity. Conversely, we recently observed three cases of rapidly progressive pneumoconiosis (CWP, 1 case; silicosis, 2 cases) characterized by very high SACE activity (>mean + 4 units of standard deviation), associated with an increased alveolar lymphocytosis. Evidence of elevated SACE levels in non pneumoconiotic coal miners lead us to suggest that interaction between mineral particles and alveolar macrophages may be in part responsible for the increased SACE production in CWP However, little information is available concerning the relationship between type of mineral particles and secretories activities of alveolar macrophages. In our study, SACE activity is not related to progression offibrosis in CWP but acute ftrms ofCWP and silicosis are associated with high SACE activity.
