Platelet aggregation in atopic dermatitis.
Many observations suggest the active role of platelets in allergic inflammation. However, this problem is poorly researched in atopic dermatitis. The aim of study was to examine the intensity and velocity of platelet aggregation and a potential relationship with some immunological parameters (total IgE and specific-IgE serum levels) in atopic dermatitis patients. Platelet aggregation was evaluated in 12 subjects with atopic dermatitis and 12 healthy, nonatopic persons, according to the Born method, in a dual-channel aggregometer, in response to three exogenous stimulators (ADP, thrombin and collagen). The intensity and velocity of platelet aggregation and total platelet counts did not differ between the two groups irrespective of the type of extrinsic stimulator used. In contrast to other atopic diseases, in atopic dermatitis platelet aggregation is not impaired.
