Strategies to prevent early-life food allergen sensitisation prior to commencement of solid foods are needed and should be the focus of future research
Elevated egg-specific Th2 cytokine responses were established prior to egg ingestion at 4months and were not significantly altered by introduction of egg
The dramatic rise in early childhood allergic diseases indicates the specific vulnerability of the immune system to early life environmental changes.
Antioxidant intakes in pregnancy may influence fetal immune programming and the risk of allergic disease.
Here, we report on a model that does not use Th2-skewing adjuvants and yet achieves sensitization solely via the nasal mucosa.
Group B streptococcus (GBS) is an important cause of early- and late-onset sepsis in the newborn. Preterm infants have markedly increased susceptibility...
Human milk is a rich source of immunomodulatory factors that influence the development of the infant immune system, including susceptibility to allergic diseases. Among these components, milk antibodies have been extensively studied for their role in protecting against infections; however, their potential contribution to allergy prevention may be equally important. The mechanisms of protection include allergen exclusion, enhanced and targeted antigen presentation, immune modulation via shaping of the infant gut microbiome, and direct regulation of gut immune responses.
Early infancy is a critical period for immune development. In addition to being the primary food source during early infancy, human milk also provides multiple bioactive components that shape the infant gut microbiome and immune system and provides a constant source of exposure to maternal microbiota. Given the potential interplay between allergic diseases and the human microbiome, this study aimed to characterise the milk microbiome of allergic mothers.
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.
