![]() 7 Worldwide prevalence of shellfish allergy was found to be 0.6% with higher incidence reported in the Asia-Pacific region. ![]() 6 In Asia, fish allergy prevalence was much higher in the Philippines (2.29%) than in Singapore (0.26%) and Thailand (0.29%). 5 In the USA, the lifetime prevalence rate for reported fish allergy was 0.4% while 0.2% of population experienced both fish and shellfish allergy. Fish allergy affects 0.2% of the general population. 4įish and shellfish are among the most common culprits of food allergies. 2, 3 Another survey in the United States on 38,480 subjects younger than 18 years of age reported a food allergy prevalence of 8.0%, where 38.7% of the cohort experienced severe allergic reaction, and 30.4% developed multiple food allergies. 1 Sensitization usually occurs by exposure through ingestion, inhalation, or skin contact, and re-exposure to milligrams of allergens is sufficient to trigger life-threatening allergic responses. A cross-sectional study in a United States cohort of 333,200 children reported a food allergy prevalence of 6.7%. IgE-mediated food allergy is a major global public health issue. Further understanding of the molecular identities and characteristics of seafood allergens can advance the development of CRD and lead to more precise diagnosis and improved clinical management of seafood allergies. Emerging diagnostic strategies, such as component-resolved diagnosis (CRD), which uses single allergenic components for assessment of epitope specific IgE, can provide critical information in predicting individualized sensitization patterns and risk of severe allergic reactions. Current clinical diagnosis of seafood allergy is a complex algorithm that includes clinical assessment, skin prick test, specific IgE measurement, and oral food challenges. The diagnosis of seafood allergies is complicated by cross-reactivity among fish allergens and between shellfish allergens and other arthropods. Parvalbumin and tropomyosin are the most common fish and shellfish allergens, respectively. Effective and accurate diagnostic workup for seafood allergy is essential for clinicians and patients. Seafood allergy is a hypersensitive disorder with increasing prevalence worldwide.
