“…This finding again confirmed and proved that tropomyosin is heat resistant in nature and can retain IgE-binding ability even after prolonged heating period (Leung et al, 1998;Motoyama et al, 2007;Kamath et al, 2013). Reese et al (1999) reported that tropomyosin can withstand heat-treatment by most known type of food processing techniques and it could be specifically due to its exceptionally stable alpha helical coiled secondary structure.…”

Consumption of shellfishes is a major cause of allergic reaction and IgE mediated hypersensitivity is an increasing health issue in sensitive individuals. Thermal stability of allergen of the flower tail shrimp Metapenaeus dobsoni was evaluated during extended period of boiling for immunoreactivity. Shrimp extracts boiled for 5 to 25 min showed increased IgE reactivity of 0.251 to 0.268 at absorbance of 490 nm in comparison to raw extract. Trpomyosin of 37 KDa was observed to withstand longer periods of boiling and found to retain IgE binding activity. Thermal treatment by means of boiling for longer duration increased the recognition of this major allergen in individuals with shrimp sensitivity. Hence, tropomyosin subjected to longer period of boiling could be used in facilitating shrimp allergy diagnosis and for detection of allergen in processed food products.

“…Myofibrillar protein, tropomyosin is reported as a major allergen in shellfishes having two identical subunits with molecular weight of 35 to 38 KDa (Shanti et al, 1993;Leung et al, 1998). It is present in both muscle and non-muscle cells.…”

Precision allergy molecular diagnostic applications (PAMD@) is increasingly entering routine care. Currently, more than 130 allergenic molecules from more than 50 allergy sources are commercially available for in vitro specific immunoglobulin E (sIgE) testing. Since the last publication of this consensus document, a great deal of new information has become available regarding this topic, with over 100 publications in the last year alone. It thus seems quite reasonable to publish an update. It is imperative that clinicians and immunologists specifically trained in allergology keep abreast of the new and rapidly evolving evidence available for PAMD@. PAMD@ may initially appear complex to interpret; however, with increasing experience, the information gained provides relevant information for the allergist. This is especially true for food allergy, Hymenoptera allergy, and for the selection of allergen immunotherapy. Nevertheless, all sIgE tests, including PAMD@, should be evaluated within the framework of a patient's clinical history, because allergen sensitization does not necessarily imply clinical relevant allergies.

“…The boy's elder brother response to oyster at the first time when he was 13 years old, which may be a cross-allergic reaction caused by mite allergy. Studies had found that there are cross-reactivities between tropomyosin in molluscs such as oyster and myosin in D.pteronyssinus and D.farinae [7]. This case report has certain limitations.…”

Background: It was estimated that about 10% of the population suffer from food allergy. Atopic dermatitis is often associated with food allergy. In this case report, we presented a child with atopic dermatitis who was sensitive to multiple food and inhaled allergens. Case report: A 3-year-old boy was admitted to the First Affiliated Hospital of Guangzhou Medical University due to skin allergy caused by drinking semi-hydrolyzed infant formula milk powder. Allergen test results showed that the boy was sensitive to multiple food and inhaled allergens. we conducted the follow-up interview by phone to completed the questionnaire. Conclusion: Atopic dermatitis children with multiple food allergies must pay attention to diet adjustment to prevent or delay the development of the disease.
