What we know: Airway inflammation and remodelling of the airway wall play an important role in the pathophysiology of asthma in adults. There is a paucity of information regarding the pathology of asthma in early childhood. Postmortem and biopsy studies of children with asthma have consistently shown an increase in the size of mucous glands, but an increase in smooth muscle is seen only in some...
BACKGROUND Childhood asthma is a complex disease with known heritability and phenotypic diversity. Although an earlier onset has been associated with more severe disease, there has been no genome-wide association study of the age of onset of asthma in children. OBJECTIVE We sought to identify genetic variants associated with earlier onset of childhood asthma. METHODS We conducted the first ...
Asthma phenotypes based on age-of-onset may be differently influenced by the interaction between variation in toll-like receptor (TLR)/CD14 genes and environmental microbes. We examined the associations between single-nucleotide polymorphisms (SNP) in the TLR/CD14 genes and asthma, and their interaction with proxies of microbial exposure (childhood farm exposure and childhood rural environment)...
BACKGROUND Childhood asthma prevalence has been shown to be higher in urban communities overall without an understanding of differences by neighborhood. OBJECTIVE To characterize the geographic variability of childhood asthma prevalence among neighborhoods in Chicago. METHODS Asthma screening was conducted among children attending 105 Chicago schools as part of the Chicago Initiative to Rai...
Asthma in adults is associated with comorbidities such as obesity, gastro-oesophageal reflux, dysfunctional breathing and mental disorders. Herein, we provide an overview of the current state of evidence on these comorbidities in childhood asthma. The prevalence, known mechanisms and possible treatment options for each comorbid condition will be discussed. Obesity is an increasing health proble...
It remains unclear whether the GSTM1 genotype interacts with tobacco smoke exposure (TSE) in asthma development. This study aimed to investigate the interactions among GSTM1 genotype, gender, and prenatal TSE with regard to childhood asthma development. In a longitudinal birth cohort in Taiwan, 756 newborns completed a 6-year follow-up, and 591 children with DNA samples available for GSTM1 geno...
