Lysozyme and IgA concentrations in serum and saliva from psoriatic patients

Acta Derm Venereol. 1992;72(2):138-40.


Significantly lower lysozyme concentrations were found in saliva of 15 psoriatic patients compared with controls, whereas in serum, lysozyme activity, was significantly higher than in controls. The concentrations of IgA in serum of psoriatic patients were significantly higher than in controls, whereas in patients' saliva IgA concentrations were not significantly different from the controls. The findings indicate that lysozyme and IgA may be of significance in the pathophysiology of psoriasis.
