Common Inhalant Pollen and Grassesallergens Profile in Patients with Atopic Dermatitis

Abstract

Atopic dermatitis is a chronic inflammatory skin reaction related to immediate-type hypersensitivity reactions and characterized by eczematous skin lesions. Pollen, of different sources, has been considered as an important causative agent of allergy worldwide. The present study aimed to investigate the sensitivity of atopic dermatitis patients towards different inhalant pollen allergens of grasses and trees. (100) persons of different ages and sexes and suffering from skin symptoms were included and subjected to skin prick testing using standard allergens solutions. The results revealed that (60%) of the tested group have allergic skin reactivity towards allergens used in the current study. Also, sensitization percent was significantly higher in females than in males and all age groups of the study population suggesting a role of the sex hormone. The highest skin reactivity was found against the Salicaceae, of the tree pollens, and five grasses mixture of the grasses pollen. Tree pollens were the main cause of atopic reaction in the studied group. The study concluded that aging and female sex may be major risk factors for developing allergic skin reactions after exposure to tree and grasses pollen. Tree pollens were significantly related to the occurrence of atopic dermatitis in the analyzed patients.
