Respiratory infection and wheezing illness are leading causes of hospitalisation in childhood, placing a significant burden on families and healthcare systems. However, reliably distinguishing children at risk of developing persistent disease from those likely to outgrow their symptoms remains a clinical challenge. Earlier identification would allow clinicians to focus care and resources on those most likely to benefit from long-term management, while reducing anxiety and uncertainty about the future for families.
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 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.
One in eight children have asthma, a chronic disease of the airways in the lungs. It results in shortness of breath, chest tightness, wheezing and coughing.
Asthma affects more than 300 million people worldwide and is frequently associated with other medical conditions in adults, including chronic obstructive pulmonary disease, ischaemic heart disease, and stroke. Despite the huge burden, there has been little progress toward prevention and cure, possibly related to a one-size-fits-all approach.
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.
Asthma affects > 10% of children in Australia and New Zealand (NZ), with up to 5% of those having severe disease, presenting a management challenge. We aimed to survey tertiary paediatric respiratory services across Australia and NZ using a custom-designed questionnaire, to conduct a cross-sectional observational study of the numbers of children with problematic severe asthma seen, the number treated with biologic therapy, outpatient clinic/multidisciplinary team services available, investigations and tools routinely used and approaches utilised for transition to adult care.
Respiratory oscillometry (or the forced oscillation technique) is a highly practical lung function test that can be applied in a wide range of clinical scenarios in children and adults, including the clinic, intensive care unit, patient home monitoring and emergency departments. Oscillometry measurements complement spirometry in detecting abnormal lung function, measuring effects of treatment such as inhaled corticosteroids or bronchodilators, and changes due to disease activity.
Excessive production, secretion, and retention of abnormal mucus is a pathological feature of many obstructive airways diseases including asthma. Azithromycin is an antibiotic that also possesses immunomodulatory and mucoregulatory activities, which may contribute to the clinical effectiveness of azithromycin in asthma.
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.
