Studies examining associations of early-life cat and dog ownership with childhood asthma have reported inconsistent results. Several factors could explain these inconsistencies, including type of pet, timing, and degree of exposure. Our aim was to study associations of early-life cat and dog ownership with asthma in school-aged children, including the role of type (cat vs dog), timing (never, prenatal, or early childhood), and degree of ownership (number of pets owned), and the role of allergic sensitization.
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.
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.
Allergic diseases are rising worldwide, especially in childhood, and their clinical diversity increasingly exposes the limits of traditional phenotype-based classifications. Genetic susceptibility, environmental exposures, epithelial barrier biology, and immune pathways interact to shape highly variable disease trajectories and treatment responses. In this context, precision medicine is no longer only an aspirational concept, but a practical effort to define meaningful endotypes, identify clinically useful biomarkers, and connect biological insight to prevention and care.
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.
Peanut allergy is the most common childhood-onset, persistent food allergy. Peanut oral immunotherapy (OIT) is a potential treatment, but few studies prospectively examine the outcome of peanut OIT in young children using parent-measured doses compared to standard care (peanut avoidance).
Allergic sensitization and reduced ability to respond to viral infections may contribute to virus-induced wheeze and asthma development in young children. Plasmacytoid dendritic cells (pDC) are rare immune cells that produce type I interferons (IFN-I) and play a key role in orchestrating immune responses against viruses.
This was a single center prospective clinical observational comparative biomarker study that included 25 dogs with anaphylaxis (evidence of insect exposure, acute dermatological signs, and other organ involvement), 30 dogs with other critical illness, and 20 healthy dogs.
Research question: Are asthma and allergies more common in adolescents conceived with assisted reproductive technologies (ART) compared with adolescents conceived without?
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.
