Recent data indicate that cystic fibrosis (CF) airway mucus is anaerobic. This suggests that Pseudomonas aeruginosa infection in CF reflects biofilm formation and persistence in an anaerobic environment. P. aeruginosa formed robust anaerobic biofilms, the viability of which requires rhl quorum sensing and nitric oxide (NO) reductase to modulate or prevent(More)
BACKGROUND Obesity is an independent risk factor for morbidity and mortality from pandemic influenza H1N1. Influenza is a significant public health threat, killing an estimated 250,000-500,000 people worldwide each year. More than one in ten of the world's adult population is obese and more than two-thirds of the US adult population is overweight or obese.(More)
Recent studies suggest that inflammation plays a role in the pathogenesis of lung disease in cystic fibrosis (CF). The goal of the present study was to quantitatively compare bronchoalveolar lavage fluid (BALF) inflammation and its relation to bacterial infection, between children with CF and children with other chronic respiratory problems. Differential(More)
BACKGROUND Cystic fibrosis is a monogenic disease that deranges multiple systems of ion transport in the airways, culminating in chronic infection and destruction of the lung. The introduction of a normal copy of the cystic fibrosis transmembrane conductance regulator (CFTR) gene into the airway epithelium through gene transfer is an attractive approach to(More)
INTRODUCTION Transforming growth factor beta-1 (TGF-β₁) is an important genetic modifier of lung disease severity in cystic fibrosis (CF), yet the mechanism behind this disease association remains unknown. Initial steps in the investigation of the relationship between TGF-β₁ and CF lung disease include determining the most appropriate available biospecimen(More)
This study measured chemokines in nasal lavage fluids (NLF) from infants with respiratory syncytial virus (RSV) bronchiolitis, defined by lung hyperinflation and wheezing. Comparison was made to RSV-positive infants without bronchiolitis and RSV-negative infants with acute respiratory illnesses. RSV-positive illnesses were associated with increased(More)
High levels of neutrophils and the neutrophil-attracting chemokine interleukin (IL)-8 have been observed in the airways of patients with cystic fibrosis (CF). We hypothesized that CF respiratory epithelium produces excessive amounts of IL-8 either at baseline or after stimulation. To test this hypothesis we compared immunoreactive IL-8 release by primary(More)
BACKGROUND Children with complex airway problems see multiple specialists. To improve outcomes and coordinate care, we developed a multidisciplinary Children's Airway Center. For children with tracheostomies, aspects of care targeted for improvement included optimizing initial hospital discharge, promoting effective communication between providers and(More)
Children in a day care center underwent serial nasal lavages in order to assess nasal cytokine expression during acute upper respiratory infections (URI). Interleukin (IL)-1 beta, IL-8, IL-6, and tumor necrosis factor-alpha (TNF-alpha) were markedly elevated in nasal lavage fluid during acute URI compared to baseline, and all except TNF-alpha decreased(More)
Respiratory syncytial virus (RSV) is the most common cause of lower respiratory infection in infants and young children, but the pathogenesis of RSV-induced inflammation is not well defined. We hypothesized that in vitro infection of a human bronchial epithelial cell line (BEAS) would induce production of proinflammatory cytokines. BEAS cells were infected(More)
