The aim of the study was to evaluate the plasma levels of inflammatory mediators in subjects exposed to silica, with and without silicosis compared with unexposed control group; and to check the association between inflammatory mediators with pulmonary function, quality of life, functional capacity, and dyspnea grade. Inflammatory mediators were measured by enzyme-linked immunosorbent assay. There were 30 subjects exposed to silica and 24 control group. Interleukin-6 plasma levels were higher in subjects exposed to silica with and without silicosis than in the control group. There was a positive correlation between radiological severity and the quality of life, whereas there was a negative correlation between radiological severity and pulmonary function. A negative correlation between sTNFR1 plasma level and functional capacity was found. Interleukin-10 was negatively correlated with the quality of life total score and was positively correlated with the functional capacity and pulmonary function.
