Amphotericin B Makes Path for Lung Defense in Cystic Fibrosis Amphotericin B Makes Path for Lung Defense in Cystic Fibrosis

Amphotericin B treatment may be able to restore the infection-fighting properties of the lungs in cystic fibrosis by standing in for a missing or deficient protein channel, studies in pigs and in human lung tissue suggest.Reuters Health Information

Boston-based Vertex Pharmaceuticals Inc. has achieved one of the biggest feats to date for cystic fibrosis patients — a treatment that could benefit 90 percent of patients with the rare lung disease. The FDA approved a combination of three drugs Monday called Trikafta, which targets a mutation in the F508del gene. That genetic error is found in approximately 90 percent of patients with the rare lung disease. The drug is set to be a blockbuster product for Vertex, which makes billions annually…

CONCLUSION: A substantial proportion of infants diagnosed with CF after detection by NBS already showed evidence of lung disease. P. aeruginosa colonization was associated with increas ed Bhalla scores, highlighting the importance of this CF pathogen in early structural lung disease. The presence of bronchial wall thickening at such a young age may reflect the presence of airway inflammatory processes. The detection and quantification of structural abnormalities with the modified Bhalla score may aid in the identification of lung disease before it is clinically apparent.

Authors: Paterson SL, Barry PJ, Horsley AR Abstract Introduction: Cystic fibrosis (CF) is a complex, multi-system, genetic disease affecting over 70,000 people worldwide. The underlying defect is a mutation in the CFTR gene. Dysfunctional CFTR protein results in abnormal anion movement across epithelial membranes in affected organs. There has been a paradigm shift in CF treatment over the last decade with the advent of CFTR modulation, treatments which target this underlying genetic defect and have the potential to change the course of CF clinical disease. Areas covered: Available CFTR modulators in current clinica...

Background: In US cystic fibrosis (CF) patients, methicillin-resistant Staphylococcus aureus (MRSA) rates have tripled in the past 2 decades. Known clinical risk factors include exposure to a healthcare setting, Pseudomonas aeruginosa and CF-related diabetes. Area-level socio-environmental exposures have not been evaluated. We explored the association of area-level deprivation with MRSA prevalence in a pediatric CF Center in the Southeastern United States. Methods: Patients’ residential addresses were geocoded and linked to a composite Area Deprivation Index and Rural-Urban Commuting Area scores. The association...

Abstract Cystic fibrosis (CF) is the most common life-limiting hereditary condition of Caucasian populations and is characterised by chronic airways inflammation driving progressive structural lung damage. Despite tremendous advances in the treatment of CF and concomitant increased life expectancy for patients, chronic lung disease remains the main cause of morbidity and mortality among CF patients. While universal restoration of cystic fibrosis transmembrane conductance regulator activity remains a future hope, novel therapies aimed at reducing or preventing chronic airways inflammation and progressive structural...

Abstract In yeast Saccharomyces cerevisiae cells, some aberrant multimembrane-spanning proteins are not transported to the cell surface but form and are accumulated in endoplasmic reticulum (ER)-derived subcompartments, known as the ER-associated compartments (ERACs), which are observed as puncta under fluorescence microscopy. Here we show that a mutant of the cell surface protein Pma1, Pma1-2308, was accumulated in the ERACs, as well as the heterologously expressed mammalian cystic fibrosis transmembrane conductance regulator (CFTR), in yeast cells. Pma1-2308 and CFTR were located on the same ERACs. We also note ...

en-Foncea H Abstract During exercise, the human body maintains optimal body temperature through thermoregulatory sweating, which implies the loss of water, sodium (Na+), and other electrolytes. Sweat rate and sweat Na+ concentration show high interindividual variability, even in individuals exercising under similar conditions. Testosterone and cortisol may regulate sweat Na+ loss by modifying the expression/activity of the cystic fibrosis transmembrane conductance regulator. This has not been tested. As a first approximation, the authors aimed to determine whether basal serum concentrations of testosterone or cort...
