Lysozyme and IgA values in patients with atopic dermatitis

Ten patients with atopic dermatitis had significantly depressed lysozyme levels in saliva, compared with controls, whereas no differences were found in lysozyme activity in serum of patients and controls. The concentrations of IgA in saliva of patients with atopic dermatitis were also significantly lower than in controls, whereas IgA in patients' serum was within normal levels.
