Author information

Department of Dermatology, National Taiwan University Hospital, No. 7, Chung-Shan South Road, Taipei, Taiwan.


Allergens play an essential role in atopic dermatitis, either intrinsic or extrinsic. They provoke cutaneous inflammation via IgE-dependent and cell-mediated immune reactions. Food allergens have a well-known contribution to disease activity of atopic dermatitis, especially in infants and young children. However, the importance of inhaled allergens is still under investigation. For clinical implication, identification of individualized allergens is an ideal strategy for better control of atopic dermatitis and avoidance of atopic march. The aim of this article is to discuss the common allergens in atopic dermatitis (AD), the specificity and sensitivity of laboratory tests for allergens, and the clinical effect of various preventions.
