2024年6月8日 · Atopy is a predisposition to immunological responses against a range of antigens or allergens, leading to CD4 + Th2 differentiation and overproduction of immunoglobulin E (IgE). These mechanisms drive hypersensitivity reactions to diverse allergens.

2025年2月20日 · What is the atopic triad? The atopic triad is a term used to describe the coexistence of atopic dermatitis, also known as eczema; asthma; and allergies, like allergic rhinitis and conjunctivitis, also known as hay fever.

2024年10月3日 · Atopic diseases include asthma, allergies and eczema. They’re caused by IgE antibodies, which overreact to things they shouldn’t, like pollen or foods, causing symptoms of allergies, a rash or airway swelling. Treatments include corticosteroids, antihistamines and …

Atopic reactions are caused by localized hypersensitivity reactions to an allergen. Atopy appears to show a strong hereditary component. One study concludes that the risk of developing atopic dermatitis (3%) or atopy in general (7%) "increases by a factor of two with each first-degree family member already suffering from atopy". [14] .

2023年5月4日 · The atopic triad is when three conditions develop in one person. They include eczema, asthma, and allergic rhinitis. They may all develop together due to genetic differences causing one person’s immune system to have a heightened reaction to allergens.

Atopy is an immune disorder of hypersensitivity to common, rather innocuous environmental antigens derived from agents such as pollen and house dust mites. It is the leading cause of asthma, rhinitis, and atopic dermatitis (AD). However, allergic mechanisms do not play a central pathogenic role in AD [1,2].

2021年6月22日 · Atopy involves a collection of comorbidities that share pathogenic features, and atopic comorbidities affect outcomes of concomitant conditions rather than existing synchronously. The clinical importance of understanding the relationship of these conditions is necessary because the treatment of one condition influences the others, and the ...

Atopy refers to the genetic predisposition to have an exaggerated immune response to allergens via the overproduction of immunoglobulin E (IgE). The term is derived from the Greek word meaning “the state of being out of place”.

2022年5月17日 · During atopy, your body responds to an otherwise harmless or mild antigen by making too much of a specific antibody called immunoglobulin E (IgE). This leads to the release of histamine and other...

2024年6月8日 · Atopy is a predisposition to respond immunologically to diverse antigens or allergens, leading to CD4 + Th2 differentiation and overproduction of immunoglobulin E (IgE). The consequence of these cellular processes is the development of …
