IgE-mediated food allergies have been linked to suboptimal naïve CD4 T (nCD4T) cell activation in infancy, underlined by epigenetic and transcriptomic variation. Similar attenuated nCD4T cell activation in adolescents with food allergy have also been reported, but these are yet to be linked to specific epigenetic or transcriptional changes.
Clinical studies supported by immunological data indicate early life intervention strategies to be promising in reducing the growing global burden of food allergies. The events that predispose to food allergy, including the induction of allergen-specific immune responses, appear to be initiated early in development.
A dose of the whooping cough vaccine might reduce cases of childhood food allergies according to latest research by the Wesfarmers Centre of Vaccines and Infectious Diseases based at The Kids Research Institute Australia.
Food allergies have become more common in our community, with up to one in ten young children now affected. Reactions can range from mild hives to life threatening anaphylaxis and breathing difficulties. The most common food allergies are to egg, peanut, tree nuts, cow’s milk, fish, shellfish, sesame, wheat and soy.
Meta-analyses of randomized controlled trials have found that introducing eggs and peanuts earlier during infancy reduced egg and peanut allergy risk. Hence, infant feeding advice has dramatically changed from previous recommendations of avoidance to current recommendations of inclusion of common food allergens in infant diets.
Food allergy affects families' quality of life, can be lifelong and life-threatening, urging the identification of early modifiable risk factors. Formula feeding in the first days of life may increase the risk of cow's milk allergy, a risk often attributed to cow's milk allergens exposure. Early formula feeding also reduces the colostrum intake, the first 3 days' milk, which is rich in bioactive compounds critical for immune and gut health. This study investigates whether partial colostrum feeding increases the risk of food allergy beyond cow's milk.
The effect of breast-feeding on the development of allergic disease is uncertain
Elucidation of early life factors is critical to understand the development of allergic diseases, especially those manifesting in early life such as food allerg
The development of food allergy has been reported to be related with the changes in the gut microbiome, however the specific microbe associated with the pathogenesis of food allergy remains elusive. This study aimed to comprehensively characterize the gut microbiome and identify individual or group gut microbes relating to food-allergy using 16S rRNA gene sequencing with network analysis.
To show underlying mechanisms, we examined differences in T-cell gene expression in samples at birth and at 1 year in children with and without IgE allergy.
