The prevalence of allergic diseases across the Australian population, in all regions and age groups, is not well documented. This study aimed to describe the prevalence and distribution of five allergic diseases (allergic rhinitis, asthma, drug allergy, eczema, and food allergy) and examine differences by sociodemographic factors.
The first peanut oral immunotherapy (OIT) for children was approved by the US Food and Drug Administration (FDA) in 2020. While clinical efficacy is established, evidence on cost-effectiveness-whether the benefits outweigh the costs and adverse effects-remains limited. A variant of OIT, known as probiotic and peanut OIT (PPOIT), has shown similar efficacy in trials.
Previous reports suggested that food proteins present in human milk (HM) may trigger symptoms in allergic children during breastfeeding, but existing evidence has never been reviewed systematically.
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.
The immunological changes underpinning acquisition of remission (also called sustained unresponsiveness) following food immunotherapy remain poorly defined. Limited access to effective therapies and biosamples from treatment responders has prevented progress. Probiotic peanut oral immunotherapy is highly effective at inducing remission, providing an opportunity to investigate immune changes.
In Western countries, Asian children have higher food allergy risk than Caucasian children. The early-life environmental exposures for this discrepancy are unclear. We aimed to compare prevalence of food allergy and associated risk factors between Asian children in Singapore and Australia.
Showed for the first time that the presence of an egg-derived allergen in breast milk is associated with a reduced risk of egg allergy in children at 2.5 years of age
Australian infants who received whole-cell pertussis vaccines were less likely to be diagnosed with food allergy in childhood
This study highlights an unpredicted potential risk factor for the development of food allergy, that is, D pteronyssinus allergens in breast milk
Infant feeding practices in Australia have changed over the past decade; a large majority of infants are now fed peanut before 12 months of age
