CONTEXT Treatment strategies for cystic fibrosis (CF) lung disease include antibiotics, mucolytics, and anti-inflammatory therapies. Increasing evidence suggests that macrolide antibiotics might be beneficial in patients with CF. OBJECTIVE To determine if an association between azithromycin use and pulmonary function exists in patients with CF. DESIGN(More)
C ystic fibrosis–related diabetes (CFRD) is the most common comorbidity in people with cystic fibrosis (CF), occurring in 20% of adolescents and 40–50% of adults (1). While it shares features of type 1 and type 2 diabetes, CFRD is a distinct clinical entity. It is primarily caused by insulin insufficiency, although fluctuating levels of insulin resistance(More)
RATIONALE Cystic fibrosis (CF) is an autosomal recessive disease characterized by abnormal airways secretions, chronic endobronchial infection, and progressive airway obstruction. The use of medications to slow the progression of lung disease has led to significant improvement in survival. An evidence review of chronic medications for CF lung disease was(More)
Proteinase 3 (PR-3) is a human polymorphonuclear leukocyte (PMNL) serine proteinase that degrades elastin in vitro and causes emphysema when administered by tracheal insufflation to hamsters (Kao, R. C., Wehner, N. G., Skubitz, K. M., Gray, B. H., and Hoidal, J. R. (1988) J. Clin. Invest. 82, 1963-1973). We have determined the primary structure of several(More)
BACKGROUND AND AIMS Selenium (Se) and sulfur (S) exhibit similar chemical properties. In flowering plants (angiosperms) selenate and sulfate are acquired and assimilated by common transport and metabolic pathways. It is hypothesized that most angiosperm species show little or no discrimination in the accumulation of Se and S in leaves when their roots are(More)
CONTEXT Azithromycin is recommended as therapy for cystic fibrosis (CF) patients with chronic Pseudomonas aeruginosa infection, but there has not been sufficient evidence to support the benefit of azithromycin in other patients with CF. OBJECTIVE To determine if azithromycin treatment improves lung function and reduces pulmonary exacerbations in pediatric(More)
Cystic fibrosis (CF) is a genetic disease characterized by dehydration of airway surface liquid and impaired mucociliary clearance. As a result, there is difficulty clearing pathogens from the lung, and patients experience chronic pulmonary infections and inflammation. Clearance of airway secretions has been a primary therapy for those with CF, and a(More)
BACKGROUND Numerous improvements in diagnostic and therapeutic strategies for patients with cystic fibrosis (CF) have occurred during the past 2 decades. We hypothesized that these changes could impact trends in respiratory microbiology. METHODS Data from the Cystic Fibrosis Foundation Patient Registry were used to examine trends in the incidence and(More)
The objective of this study was to create a 5-year survivorship model to identify key clinical features of cystic fibrosis. Such a model could help researchers and clinicians to evaluate therapies, improve the design of prospective studies, monitor practice patterns, counsel individual patients, and determine the best candidates for lung transplantation.(More)
