The in vitro effect of levamisole on lymphocyte proliferation, polymorphonuclear leucocyte chemotaxis, basophil histamine release and platelet serotonin release in patients with atopic dermatitis

Abstract
The in vitro effect of levamisole (LMS) on lymphocyte, neutrophil, basophil and platelet function was investigated in patients with severe atopic dermatitis and hyper‐immunoglobulinaemia E. Lymphocyte stimulation by several concentrations of PHA, con A and PWM, polymorphonuclear leukocyte chemotaxis and basophil histamine release were unaffected by LMS (10 μg/ml). Platelet serotonin release induced by iodipamide was decreased in patient and control groups by LMS but release induced by methacholine, epinephrine and thrombin was not.
