OBJECTIVE: To evaluate the plasma levels of CCL2, CCL3, CCL11, CCL24, tumor necrosis factor alpha, sTNFR1, and sTNFR2 in subjects exposed to silica (SES) with and without silicosis compared with unexposed reference control group, and their associations with the radiological severity and duration of exposure to silica. METHODS: Fifty-seven SES; 36 with silicosis and 22 subjects in control group, were included in the study. RESULTS: CCL3, CCL24, sTNFR1, and sTNFR2 were increased in SES and in SES with silicosis than in controls. There were no differences in the levels of CCL2, CCL11, or tumor necrosis factor alpha. The sTNFR2 level was greater in SES with silicosis than in SES without silicosis. There was a positive correlation between sTNFR1 and sTNFR2 and the radiological severity and time of exposure to silica. sTNFR2 was associated with all categories of radiological severity. CONCLUSION: sTNFR2 is associated with silicosis severity and early exposure to silica.
