Secondhand smoke affect cystic fibrosis lung disease
Any exposure to secondhand smoke adversely affects both cross-sectional and longitudinal measures of lung function in individuals with cystic fibrosis CF. Variations in the gene that causes CF (CFTR) and a CF-modifier gene (TGF?1) amplify the negative effects of secondhand smoke exposure. – Exposure to secondhand smoke is associated with adverse effects on lung function among persons with cystic fibrosis, with this effect being worse for persons with certain gene variations, according to a study in the January 30 issue of Journal of the American Medical Association (JAMA).
