Allergic reactions to latex range from Type I hypersensitivity, the most serious form of reaction, to Type IV hypersensitivity. [4] Rate of onset is directly proportional to the degree of allergy: Type I responses will begin showing symptoms within minutes of exposure to latex, while Type IV responses may take hours or days to appear.
People with latex allergy often also develop allergies to bananas, kiwifruit, avocados, and some other foods. ... Skin-prick testing is easy to do and results are ...
Hevein is the main IgE-binding epitope of the major latex allergen prohevein [4] as are hevein-like protein domains in fruit class I chitinases. [5] Therefore it is a possible cause for allergen cross-reactivity between latex and banana or other fruits like chestnuts or avocadoes. [6]
Name Possible reaction(s) Remarks Balsam of Peru: Redness, swelling, itching, allergic contact dermatitis reactions, stomatitis (inflammation and soreness of the mouth or tongue), cheilitis (inflammation, rash, or painful erosion of the lips, oropharyngeal mucosa, or angles of their mouth), pruritus, hand eczema, generalized or resistant plantar dermatitis, rhinitis, conjunctivitis, and blisters.
Latex and banana sensitivity may cross-react. Furthermore, those with latex allergy may also have sensitivities to avocado, kiwifruit, and chestnut. [57] These people often have perioral itching and local urticaria. Only occasionally have these food-induced allergies induced systemic responses.
Oral allergy syndrome (OAS) or pollen-food allergy syndrome (PFAS) is a type of allergy classified by a cluster of allergic reactions in the mouth and throat in response to eating certain (usually fresh) fruits, nuts, and vegetables. It typically develops in adults with hay fever. [1] It is not usually serious. [2]
Cross reactivity may also occur between a pathogen and a protein found on a non-pathogen (i.e. food.) There may even be cross reactivity between two non-pathogens; [5] for example, Hevein-like protein domains are a possible cause for allergen cross-reactivity between latex and banana. [6]
A patch test is a diagnostic method used to determine which specific substances cause allergic inflammation of a patient's skin.. Patch testing helps identify which substances may be causing a delayed-type allergic reaction in a patient and may identify allergens not identified by blood testing or skin prick testing.
