The goal of this study is characterize the changes in bacterial diversity of the upper respiratory tracts of infants with cystic fibrosis (CF). Another goal is to determine when CF patients become colonized with pathogenic bacteria that are responsible for the lethal lung damage in children with CF. Ten subjects will be recruited into the study. Throat swabs will be collected at 6-8 weeks of age, 3 months, 6 months, 9 months, and 12 months of age in order to chart any changes in the bacterial populations of the respiratory tract. Clinical data will also be collected to evaluate the possible influence of external factors on changes in the microbial communities. This study will provide preliminary data on whether probiotics can eradicate the colonization of the respiratory tract by pathogenic bacteria.

The purpose of this study is to identify all the bacterial species present in the respiratory tracts of patients with Cystic Fibrosis (CF), and to connect them with clinical information. T...
The purpose of this study is to determine which biological marker, or association of biological markers, best predict clinical response of cystic fibrosis patients to CFTR modulators.
The aim of this pilot study is to demonstrate the feasibility of viral biomolecular diagnosis in sputum compared to nasopharyngeal swab in cystic fibrosis acute respiratory infection.
Cystic fibrosis is a genetic disease caused by mutation of the cystic fibrosis transmembrane conductance regulator (CFTR). The purpose of the study is to investigate the effects of miglust...
In order to further enable physiopathology studies, the aim of this project is to validate an in vitro model of cystic fibrosis created using induced pluripotent stemcell (iPS) differentia...
Pathogen surveillance is challenging but crucial in children with cystic fibrosis-who are often non-productive of sputum even if actively coughing-because infection and lung disease begin early in lif...
The risk of vitamin E deficiency is of primary concern in cystic fibrosis patients. However, early diagnosis and routine vitamin E supplementation can lead to its normal or even high levels. In the pr...
In healthy lungs, epithelial sodium channel (ENaC) is regulated by short, palate, lung, and nasal clone 1 (SPLUNC1). In cystic fibrosis (CF), ENaC is hyperactivated in part due to a loss of SPLUNC1 fu...
Cystic fibrosis diagnosis is dependent on the chloride ion concentration in the sweat test (≥60mEq/mL - recognized as the gold standard indicator for cystic fibrosis diagnosis). Moreover, the saliva...
An autosomal recessive genetic disease of the EXOCRINE GLANDS. It is caused by mutations in the gene encoding the CYSTIC FIBROSIS TRANSMEMBRANE CONDUCTANCE REGULATOR expressed in several organs including the LUNG, the PANCREAS, the BILIARY SYSTEM, and the SWEAT GLANDS. Cystic fibrosis is characterized by epithelial secretory dysfunction associated with ductal obstruction resulting in AIRWAY OBSTRUCTION; chronic RESPIRATORY INFECTIONS; PANCREATIC INSUFFICIENCY; maldigestion; salt depletion; and HEAT PROSTRATION.
A chloride channel that regulates secretion in many exocrine tissues. Abnormalities in the CFTR gene have been shown to cause cystic fibrosis. (Hum Genet 1994;93(4):364-8)
A strain of mice widely studied as a model for cystic fibrosis. These mice are generated from embryonic stem cells in which the CFTR (cystic fibrosis transmembrane conductance regulator) gene is inactivated by gene targeting. As a result, all mice have one copy of this altered gene in all their tissues. Mice homozygous for the disrupted gene exhibit many features common to young cystic fibrosis patients, including failure to thrive, meconium ileus, and alteration of mucous and serous glands.
A species of STENOTROPHOMONAS, formerly called Xanthomonas maltophilia, which reduces nitrate. It is a cause of hospital-acquired ocular and lung infections, especially in those patients with cystic fibrosis and those who are immunosuppressed.
Intestinal obstruction caused by congealed MECONIUM in the distal ILEUM and CECUM. It presents shortly after birth as a failure to pass meconium and frequently occurs in infants with CYSTIC FIBROSIS.
