What is atopic sensitization?
Atopic sensitization is considered IgE positivity or prick test positivity to any common food- or air-borne allergen. Atopic conditions are considered: atopic dermatitis, allergic rhinitis (hay fever), allergic asthma, atopic keratoconjunctivitis.
What is allergic sensitization?
Allergic sensitization is the outcome of a complex interplay between the allergen and the host in a given environmental context. The first barrier encountered by an allergen on its way to sensitization is the mucosal epithelial layer.
What happens during sensitization?
For example, by being stung by a bee. Then your immune system memorizes the particular structure of the allergen so that it can produce specific IgE antibodies in defense. This process is called sensitization. You’re sensitized when you have specific IgE antibodies in your blood.
Is asthma atopic?
Allergic (or atopic) asthma is asthma that’s triggered by allergens like pollen, pets and dust mites. About 80% of people with allergic asthma have a related condition like hay fever, eczema or food allergies.
What is atopic individual?
Atopy is defined as a personal and/or familial tendency, usually in childhood or adolescence, to become sensitized and produce IgE antibodies in response to ordinary exposure to allergens, usually proteins.
What is an example of sensitization?
Sensitization is the strengthening of a neurological response to a stimulus due to the response to a secondary stimulus. For example, if a loud sound is suddenly heard, an individual may startle at that sound. It is essentially an exaggerated startle response, and is often seen in trauma survivors.
What is the most common atopic disorder?
Atopic dermatitis, also called eczema, is a chronic, relapsing inflammatory disease of the skin that leads to itching and risks for skin infection. It is the most common skin disease in children: about 10% to 20% of children in the United States and Western Europe have atopic dermatitis.
