Atopic syndrome

• "Atopic syndrome is a predisposition toward developing certain allergic hypersensitivity reactions. Atopy may have a hereditary component, although contact with the allergen must occur before the hypersensitivity reaction can develop."
•  Many EE patients suffer from concurrent autoimmune and allergic disease.
• Patients with atopy usually develop what is referred to as the “allergic triad” of symptoms, i.e., eczema (atopic dermatitis), hay fever (allergic rhinitis), and allergy-induced asthma (allergic asthma).
• They also have a tendency to have food allergies, and other symptoms characterized by their hyperallergic state. For example, eosinophilic esophagitis is found associated with atopic allergies.
• Although atopy has various definitions, in general, it is defined by the presence of elevated levels of total and allergen-specific IgE in the serum, leading to positive skin-prick tests to common allergens.
• There is a strong genetic predisposition toward atopic allergies, especially on the maternal side.
