LYZ and monocytic leukemia: For example, there is an increase in lysozyme concentrations in case of oral infections, oral squamous cell carcinoma, coronary artery disease [20], monocytic leukemia [21,22,23,24], Crohn’s disease, sarcoidosis and renal tubular damage [25,26,27], resulting in elevated saliva, serum and urine levels (reaching, and in some cases overcoming, 100 mg/L) [14], while a decrease occurs in case of neonatal septicemia [28].
