Study on Skin Tests of 43 Patients with Seasonal Contact Dermatitis / 中华皮肤科杂志

ABSTRACT

To study the etiology and pathogenesis of seasonal contact dermatitis (SG),some skin tests including pollen allergen patch test were performed in 43 cases of SG.Sixty-two patients with al- lergic contact dermatitis(NSG) and 50 healthy individual(HG) were used as control.The results showed that the level and positivity rate of total serum IgE in SG,and the positivity rate of specific IgE,pollen allergen prick test and patch test in SG were higher than those in NSG and HG.The speeific IgE,pollen allergen prick test and pollen allergen patch test were significantly correlated,and showed high consis- tency.These results indieate that the pathogenesis of seasonal contact dermatitis he obviously associated with pollen allergen-induced IgE-mediated late-phase reaction.
