Shellfish cross reactivity
WebNov 2, 2016 · A recent study has shown that allergens other than tropomyosin, such as arginine kinase, might also be responsible for cross-reactivity between shellfish and inhalant invertebrate allergen sources [27, 43]. In addition, hemocyanin has been demonstrated to be cross-reactive and is also a known cockroach allergen [44, 45]. WebCross-reactivity with species that are not closely related is common in shellfish-allergic patients, as many of shellfish allergens are widely distributed panallergens in invertebrates. Cross-reactivity with house dust mites is well known, but other species can also be …

WebCross-reactivity is defined as the recognition of distinct antigens by the same IgE antibody, demonstrable by in vivo and in vitro tests, which clinically manifests as reactions caused by antigens homologous to different species. Subclinical sensitization can also occur, giving rise to patients sensitized to particular fish or shellfish but who ... WebThe strength of shellfish protein cross-reactivity explains a common observation that one may test positive to multiple species within the crustacean family, or mollusk family.
