Serum SAA levels in sensitized sarcoidosis sub-groups. Median SAA levels between bacterial sensitized and/or autoantigen sensitized and inorganic agent sensitized sarcoidosis patients did not significantly differ. The percentage of patients using immunosuppressive medication did not significantly differ between the bacterial and/or autoantigen and inorganic sensitized group (33.3% vs. 46.2% respectively, p = 0.355) nor did the percentage of patients using prednisone (20.8% vs. 42.3%, p = 0.104). Bacterial: sensitization to mycobacterial antigens or C. acnes catalase, autoantigen: sensitization to vimentin, inorganic: sensitization to aluminum, beryllium, zirconium, or silica. p-values were calculated using Mann–Whitney U test.
