BACKGROUND Several indicators suggest that food allergy in infants is common and possibly increasing. Few studies have used oral food challenge to measure this phenomenon at the population level. OBJECTIVE To measure the prevalence of common IgE-mediated childhood food allergies in a population-based sample of 12-month-old infants by using predetermined(More)
BACKGROUND The evidence on whether the atopic march observed in childhood (ie, the progression from eczema to allergic rhinitis and asthma) extends to adulthood is sparse, and there is no evidence on whether the progression leads to a specific phenotype of asthma. OBJECTIVE We sought to assess whether childhood eczema and rhinitis are risk factors for(More)
BACKGROUND Infant feeding guidelines have long recommended delaying introduction of solids and allergenic foods to prevent allergy in high-risk infants, despite a paucity of evidence. OBJECTIVE We aimed to determine whether confirmed egg allergy in 12-month-old infants is associated with (1) duration of breast-feeding and (2) ages of introducing egg and(More)
BACKGROUND The incidence of hospital admissions for food allergy-related anaphylaxis in Australia has increased, in line with world-wide trends. However, a valid measure of food allergy prevalence and risk factor data from a population-based study is still lacking. OBJECTIVE To describe the study design and methods used to recruit infants from a(More)
BACKGROUND Measurement of whole peanut-specific IgE (sIgE) is often used to confirm sensitization but does not reliably predict allergy. Ara h 2 is the dominant peanut allergen detected in 90% to 100% of patients with peanut allergy and could help improve diagnosis. OBJECTIVES We sought to determine whether Ara h 2 testing might improve the accuracy of(More)
PURPOSE OF REVIEW The purpose of the present review is to describe the epidemiology of food-induced, medication-induced, drug-induced, and insect sting-induced anaphylaxis; to summarize recent changes in the incidence of anaphylaxis internationally; and to discuss recent insights into potential risk factors for anaphylaxis. RECENT FINDINGS Recent studies(More)
Food allergy seems to represent a new spectrum of disease that has elicited significant community concern and extended waiting lists for allergists and gastroenterologists alike. The apparent rise in prevalence of IgE-mediated food allergy (and associated risk of anaphylaxis) has been postulated to result from effects of a "modern lifestyle" but as yet(More)
BACKGROUND Although egg allergy is the most common food allergy in infants and young children, risk factors for egg allergy remain largely unknown. This study examined the relationship between environmental and demographic factors and egg allergy in a population-based infant cohort. METHODS In a study of 5276 infants (HealthNuts), infants underwent skin(More)
