Pulmonary exacerbations pose a significant clinical burden on people with cystic fibrosis (pwCF). Whether management of exacerbations should change in the context of modulator therapy is unclear. We describe the characteristics, treatment and lung function outcomes of pulmonary exacerbations requiring intravenous antibiotic therapy (PERITs) in a contemporary Australian cohort of pwCF, in an era of rapidly broadening access to modulator therapy.
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.
Cystic fibrosis (CF) is the most common chronic, life-shortening genetic condition affecting young Australians. There is no cure but researchers are working to prevent the onset of lung disease.
Multiple-breath washout (MBW) is an established technique to assess functional residual capacity (FRC) and ventilation inhomogeneity in the lung. Indirect calculation of nitrogen concentration requires accurate measurement of gas concentrations.

Newly developed quantitative chest computed tomography (CT) outcomes designed specifically to assess structural abnormalities related to cystic fibrosis (CF) lung disease are now available. CFTR modulators potentially can reduce some structural lung abnormalities. We aimed to investigate the effect of CFTR modulators on structural lung disease progression using different quantitative CT analysis methods specific for people with CF (PwCF).
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.
For those born with cystic fibrosis (CF), hyper-concentrated mucus with a dysfunctional structure significantly impacts CF airways, providing a perfect environment for bacterial colonization and subsequent chronic infection. Early treatment with antibiotics limits the prevalence of bacterial pathogens but permanently alters the CF airway microenvironment, resulting in antibiotic resistance and other long-term consequences.
SHIP-CT showed that 48-week treatment with inhaled 7% hypertonic saline (HS) reduced airway abnormalities on chest CT using the manual PRAGMA-CF method relative to isotonic saline (IS) in children aged 3-6 years with cystic fibrosis (CF). An algorithm was developed and validated to automatically measure bronchus and artery (BA) dimensions of BA-pairs on chest CT. Aim of the study was to assess the effect of HS on bronchial wall thickening and bronchial widening using the BA-analysis.
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.
