Improving standards of care and new therapeutics means individuals with cystic fibrosis are living longer, but this brings an increased risk non-communicable diseases, especially cardiovascular disease (CVD). To improve both longevity quality life, it is important to consider CVD prevention in those fibrosis.

Glutathione is an important antioxidant in the lungs but its concentration is low in the airways of patients with cystic fibrosis. Whether this deficit occurs from an early age or how oxidative stress contributes to lowering glutathione is unknown. We measured glutathione, its oxidation products, myeloperoxidase, and biomarkers of hypochlorous acid in bronchoalveolar lavage from children with c...

UNLABELLED Although the cytokine profile in nasal polyposis is well documented, little is known about cytokines associated to cystic fibrosis. AIM Assess the expression of cytokines IL not4, IL not5, IL not6, IL not8, GM not-CSF and IFN not-y, analyzed through RT-PCR, in the polyps of patients with cystic fibrosis. MATERIALS AND METHODS A cross-sectional, prospective study was carried out w...

Nasal ciliary function and mucociliary clearance were studied in patients with cystic fibrosis and in three control groups. Ciliary beat frequency and nasal clearance time were measured in groups of 10 subjects with cystic fibrosis, sinusitis and bronchiectasis and age and sex-matched control subjects. Ciliary beat frequency was also measured in normal subjects matched as bronchiectasis control...

The hypoxic environment of cystic fibrosis airways allows the persistence of facultative anaerobic bacteria, which can produce short-chain fatty acids (SCFAs) through fermentation. However, the relevance of SCFAs in cystic fibrosis lung disease is unknown. We show that SCFAs are present in sputum samples from cystic fibrosis patients in millimolar concentrations (mean±sem 1.99±0.36 mM).SCFAs po...

Newborn screening for cystic fibrosis offers the opportunity for early intervention and improved outcomes. This summary, resulting from a workshop sponsored by the Cystic Fibrosis Foundation to facilitate implementation of widespread high quality cystic fibrosis newborn screening, outlines the steps necessary for success based on the experience of existing programs. Planning should begin with a...

The epithelial response to bacterial airway infection, a common feature of lung diseases such as chronic obstructive pulmonary disease and cystic fibrosis, has been extensively studied. However, its impact on cystic fibrosis transmembrane conductance regulator (CFTR) channel function is not clearly defined. Our aims were, therefore, to evaluate the effect of Pseudomonas aeruginosa on CFTR funct...

BACKGROUND The psychosocial functioning of adolescents and young adults with cystic fibrosis still living in the parental home was investigated. With its proven genetic aetiology cystic fibrosis is an ideal model with which to assess the impact of a chronic and life threatening disorder on family and individual psychological and social functioning. METHODS Twenty nine patients with cystic fib...

1. Measurements of resting metabolic rate were made by open-circuit indirect calorimetry in 78 unrelated cystic fibrosis patients and 30 healthy control subjects. The aims of this study were: (i) to determine the range of variability in resting metabolic rate in cystic fibrosis, (ii) to relate this to pulmonary function and body size, and (iii) to investigate the hypothesis that, in cystic fibr...

Cystic fibrosis results from defects in the gene encoding a cyclic adenosine monophosphate-dependent chloride ion channel known as the cystic fibrosis transmembrane conductance regulator (CFTR). To create an animal model for cystic fibrosis, mice were generated from embryonic stem cells in which the CFTR gene was disrupted by gene targeting. Mice homozygous for the disrupted gene display many f...
