LYZ and latent syphilis: The increase in serum lysozyme level was significant for patients with presumed sarcoidosis with respect to AS (p = 0.0001), BD (p = 0.0001), presumed latent TB (p = 0.001), presumed latent syphilis (p = 0.033), and control group (p = 0.0001) (Table 5) The mean (SD) differences of serum lysozyme levels between control group and AS, BD, presumed latent TB, presumed latent syphilis were −0.928 (1.531), −1.175 (1.530), −1.790 (1.617), and −0.784 (2.328) respectively (Table 5).
