Prospective birth cohort studies tracking asthma initiation and consolidation in community cohorts have identified viral infections occurring against a...
The aim of this study was to explore associations between severe respiratory infections and atopy in early childhood with persisting wheeze and asthma.
Information is accumulating which implicates airway inflammation resulting from respiratory viral infections, acting against a background of atopy.
In this study, using a mouse model, we determined whether vitamin D deficiency in utero and during early life modulated the severity of asthma.
The goal of the current study was to investigate asthma and mental health among youth in the community.
Asthma remission has emerged as a potential therapeutic goal. However, definitions of remission have primarily focused on adult populations, with limited consensus on how remission should be defined in children.
Asthma exacerbations in children are associated with respiratory viral infection and atopy, resulting in systemic immune activation and infiltration of immune cells into the airways. The gene networks driving the immune activation and subsequent migration of immune cells into the airways remains incompletely understood. Cellular and molecular profiling of PBMC was employed on paired samples obtained from atopic asthmatic children during acute virus-associated exacerbations and later during convalescence.
Poor maternal diet during pregnancy is a risk factor for severe lower respiratory infections in the offspring, but the underlying mechanisms remain elusive. Here, we demonstrate that in mice a maternal low-fiber diet led to enhanced LRI severity in infants because of delayed plasmacytoid dendritic cell recruitment and perturbation of regulatory T cell expansion in the lungs.
The way the immune system operates differs between males and females. This is due to both differential expression of immune-related genes from the sex chromosomes as well as the immune modulatory properties of sex hormones. Together, these effects contribute to a skewed prevalence of disease and disease course between males and females, including allergic-, infectious-, autoimmune-, and cancerous disease.
Asthma is among the commonest noncommunicable diseases of childhood and often occurs with other atopic comorbidities. A previous case-control study found evidence that compared to children who received acellular pertussis (aP) vaccines in early infancy, children who received one or more doses of whole-cell pertussis (wP) vaccine had lower risk of developing IgE-mediated food allergy. We hypothesized that wP vaccination in early infancy might protect against atopic asthma in childhood.
