atopy[′ad·ə·pē] (medicine) Clinically evident hypersensitivity. atopyenUK
atopy [at´o-pe] a clinical hypersensitivity state or allergy with a hereditary predisposition; the tendency to develop an allergy is inherited, although the specific clinical form (such as hay fever or asthma) is not. The antibody reagin is involved. Called also atopic, hereditary, or spontaneous allergy.at·o·py (at'ō-pē), A genetically determined state of hypersensitivity to environmental allergens. Type I allergic reaction is associated with the IgE antibody and a group of diseases, principally asthma, hay fever, and atopic dermatitis. [G. atopia, strangeness, fr. a- priv. + topos, a place] atopy A state of increased sensitivity to common antigens (e.g., house dust, animal dander, pollen) with increased production of allergen-specific IgE. Atopy may have a hereditary component, given the increased susceptibility to hay fever, asthma and eczematoid dermatitis.atopy Clinical immunology A state of ↑ sensitivity to common antigens–eg, house dust, animal dander, pollen, with ↑ production of allergen-specific IgE; atopy may have a hereditary component as there is ↑ susceptibility to hay fever, asthma, and eczematoid dermatitis. See Asthma, Atopic dermatitis, Hay fever. at·o·py (at'ŏ-pē) A genetically determined state of hypersensitivity to environmental allergens. Type I allergic reaction is associated with the IgE antibody and a group of diseases, principally asthma, hay fever, and atopic dermatitis. [G. atopia, strangeness, fr. a- priv. + topos, a place]atopy A state giving rise to an allergy in which the reaction occurs at a different site from that of contact with the causal ALLERGEN. Atopy is an immediate hypersensitivity reaction associated with IMMUNOGLOBULIN E (IgE) and is a maternally transmitted genetic disorder due to mutations in a gene on chromosome 11. This gene codes for the IgE receptor on MAST CELLS. Atopy causes a proneness to ASTHMA, HAY FEVER and ECZEMA (atopic DERMATITIS). The term is derived from the Greek a , not and topos , a place.AtopyA state that makes persons more likely to develop allergic reactions of any type, including the inflammation and airway narrowing typical of asthma.Mentioned in: Asthmaat·o·py (at'ŏ-pē) A genetically determined state of hypersensitivity to environmental allergens.
