Substrate-dependent metabolomic signatures of myeloperoxidase activity in airway epithelial cells: Implications for early cystic fibrosis lung disease

Myeloperoxidase is released by neutrophils in inflamed tissues. MPO oxidizes chloride, bromide, and thiocyanate to produce hypochlorous acid, hypobromous acid, and hypothiocyanous acid, respectively. These oxidants are toxic to pathogens, but may also react with host cells to elicit biological activity and potential toxicity. In cystic fibrosis and related diseases, increased neutrophil inflammation leads to increased airway MPO and airway epithelial cell exposure to its oxidants.

Detection of bile acids in bronchoalveolar lavage fluid defines the inflammatory and microbial landscape of the lower airways in infants with cystic fibrosis

Cystic Fibrosis (CF) is a genetic condition characterized by neutrophilic inflammation and recurrent infection of the airways. How these processes are initiated and perpetuated in CF remains largely unknown. We have demonstrated a link between the intestinal microbiota-related metabolites bile acids and inflammation in the bronchoalveolar lavage fluid from children with stable CF lung disease.

Improving screening in a paediatric cohort for cystic fibrosis-related diabetes: A quality improvement project

The SPEC score—A quantifiable CT scoring system for primary ciliary dyskinesia

Structural lung changes seen on computed tomography scans in persons with primary ciliary dyskinesia are currently described using cystic fibrosis derived scoring systems. Recent work has shown structural changes and frequencies that are unique to PCD, indicating the need for a unique PCD-derived scoring system.

The feasibility of using electrical impedance tomography to guide positive pressure airway clearance in children with cystic fibrosis and tracheobronchomalacia

Positive expiratory pressure devices are frequently used for airway clearance in children with cystic fibrosis and tracheobronchomalacia. This study aimed to establish if electrical impedance tomography is a feasible measure to titrate pressures in non-sedated children.

Young children with cystic fibrosis and tracheobronchomalacia have longer and more frequent hospital admissions

Tracheobronchomalacia (TBM) is characterised by abnormal collapsibility of the trachea and bronchi, often seen in children with cystic fibrosis (CF). This study aims to determine the impact of TBM on hospital admissions in young children with CF.

A Small Device May Deliver King-Sized Solutions for Patients With an Exacerbation of Cystic Fibrosis

The aim is to examine whether using a portable spring-infusor device to deliver antibiotics compared with a standard infusion pump (SIP) translated to (i) improve health outcomes, (ii) reduce the length of stay (LoS), and (iii) reduce cost for treatment of exacerbations of cystic fibrosis.

Early nasal microbiota and subsequent respiratory tract infections in infants with cystic fibrosis

Respiratory tract infections (RTIs) drive lung function decline in children with cystic fibrosis (CF). While the respiratory microbiota is clearly associated with RTI pathogenesis in infants without CF, data on infants with CF is scarce. We compared nasal microbiota development between infants with CF and controls and assessed associations between early-life nasal microbiota, RTIs, and antibiotic treatment in infants with CF.

Cyanide in bronchoalveolar lavage is not diagnostic for Pseudomonas aeruginosa in children with cystic fibrosis

We investigated whether cyanide in bronchoalveolar lavage (BAL) fluid could be used as an early diagnostic biomarker of infection in kids with cystic fibrosis
