"A low-risk penicillin allergy was added to her chart as a 2 year old," said Stone, who is treating Woerner. "For 30+ years, this meant whenever she got sick, her doctors had to work around it."
A review identified "the eliciting dose for an allergic reaction in 1% of the population" as the threshold reference dose for certain foods (such as cow's milk, egg, peanut and other proteins) to provide food manufacturers with guidance for developing precautionary labeling and give consumers a better idea of what might be accidentally in a ...
The terms CCD or CCDs describe protein-linked carbohydrate structures responsible for the phenomenon of cross-reactivity of sera from allergic patients towards a wide range of allergens from plants and insects. In serum-based allergy diagnosis, antibodies of the IgE class directed against CCDs therefore give the impression of polysensitization ...
Cross-reactivity, in a general sense, is the reactivity of an observed agent which initiates reactions outside the main reaction expected. This has implications for any kind of test or assay , including diagnostic tests in medicine, and can be a cause of false positives .
People with fish allergies have a 50% likelihood of being cross reactive with another fish species, [14] but some individuals are only allergic to one species, such as; tilapia [15] salmon, [13] or cod. A proper diagnosis is considered complicated due to these cross reactivity between fish species and other seafood allergies. [16]
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]
Nevertheless, the risk of cross-reactivity is sufficient to warrant the contraindication of all β-lactam antibiotics in patients with a history of severe allergic reactions (urticaria, anaphylaxis, interstitial nephritis) to any β-lactam antibiotic. Rarely, allergic reactions have been triggered by exposure from kissing and sexual contact ...
Around 10% of the U.S. population reports having an allergy to penicillin. In reality, it is believed that less than 1% are truly allergic to the life-saving antibiotic, said Dr. Kim Frodl, UW-Eau ...
