Reduced transforming growth factor β1 (TGF-β1) in the repair of airway epithelial cells of children with asthma

Evidence into the role of TGF-β1 in airway epithelial repair in asthma is still controversial. This study tested the hypothesis that the reduced TGF-β1 levels previously observed in paediatric asthmatic airway epithelial cells directly contribute to the dysregulated repair seen in these cells.

Alpha-1 antitrypsin mitigates the inhibition of airway epithelial cell repair by neutrophil elastase

Free NE activity is deleterious for epithelial homeostasis and support the hypothesis that proteases in the airway contribute to CF structural lung disease

Impact of lung disease on respiratory impedance in young children with cystic fibrosis

The present study investigated whether lung function measured by forced oscillation technique would be impaired in the presence of infection,...

Protocol for a study of the psychosocial determinants of health in early childhood among children with cystic fibrosis

This protocol outlines the study aims to investigate the causal effect of psychosocial functioning, parenting and attachment on physical health outcomes in...

Respiratory tract exacerbations revisited: Ventilation, inflammation, perfusion, and structure (VIPS) monitoring to redefine treatment

For cystic fibrosis (CF) patients older than 6 years there are convincing data that suggest respiratory tract exacerbations (RTE) play an important role in...

Matrix metalloproteinase activation by free neutrophil elastase contributes to bronchiectasis progression in early cystic fibrosis

The aim of this study was to assess if MMP activation positively correlates with neutrophil elastase activity, disease severity and bronchiectasis in young...

Reversibility of trapped air on chest computed tomography in cystic fibrosis patients

To investigate changes in trapped air volume and distribution over time and compare computed tomography (CT) with pulmonary function tests for determining...

Feasibility of parental collected nasal swabs for virus detection in young children with cystic fibrosis

No evidence to demonstrate relationships with symptoms and viruses, prolonged symptoms, prolonged shedding or patterns of virus infections in CF

House dust mite induced lung inflammation does not alter circulating vitamin D levels

We hypothesized that allergic inflammation decreases the level of circulating 25(OH)D and tested this using a mice model of house dust mite (HDM) induced...

Early respiratory infection is associated with reduced spirometry in children with cystic fibrosis

We hypothesized that the presence of these markers of cystic fibrosis lung disease in the first 2 years of life would be associated with reduced lung...
