The Effects of Long Term Inhalation of Hypertonic Saline in Subjects With Cystic Fibrosis
The effect of long term inhalation of hypertonic saline in subjects with cystic fibrosis on lung function, incidence of respiratory tract infections, quality of life, quantitative microbiology and sputum cytokine profile. The hypothesis is that regular inhalation of nebulised hypertonic saline will have a beneficial effect on lung function and other clinical outcomes with no adverse effects on infection and inflammation in adults and children with cystic fibrosis.
The study intervention is nebulised hypertonic (7%) saline (Active) or nebulised normal (0.9%) saline (Control) twice per day for 336 days. At a screening visit, subjects will complete quality of life questionnaires, be questioned regarding their medical history, undergo physical examination and spirometry, and will be requested to provide a sputum sample. The subject is then supervised taking their first dose to ensure the correct procedure is used and there are no adverse effects. The subject then commences taking the trial solution at home, and once a week completes a diary card to monitor factors such as respiratory tract infections and medication use. Subsequent visits are scheduled at Days 28, 84, 168, 252, 334, and 336, at which the same investigation are performed as at the screening visit.

Saline Solution, Hypertonic
Hypertonic sodium chloride solution. A solution having an osmotic pressure greater than that of physiologic salt solution (0.9 g NaCl in 100 ml purified water).
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.
Cystic Fibrosis Transmembrane Conductance Regulator
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)
Mice, Inbred Cftr
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.
Despite the lack of trials proving the efficacy of DNase in non cystic fibrosis patients, it is currently heavily used in this population. In fact, per evidence of barcode scanning via Med...
The purpose of this study is to determine whether the daily inhalation of nebulised hypertonic saline (6%) will decrease the incidence of pulmonary exacerbations and increase the quality o...
This study is examining the effect of hypertonic saline compared to placebo on the Lung Clearance Index in Cystic Fibrosis patients.
Previous work demonstrated that inhaled hypertonic saline (HS) reduces exacerbation frequency and improves lung function in adults with cystic fibrosis (CF). It is unclear, however, wheth...
The general objective is to elucidate the mechanisms whereby sex hormones may modulate the severity of respiratory disease. An important component of this proposal is a systematic and inte...
The aim of our study was to evaluate the tolerance of two inhaled hypertonic saline solutions (HS) in patients with cystic fibrosis.
ABSTRACT: BACKGROUND: Cystic fibrosis is a debilitating lung disease due to mutations in cystic fibrosis transmembrane conductance regulator protein (CFTR) that are associated with chronic infections...
The effects of hypertonic saline on hypothalamic paraventricular nucleus (PVN) parvocellular neurons were examined using whole-cell patch-clamp technique. Under current-clamp, 50% (41/82) of parvocell...
Purpose The use of hypertonic saline injection in trauma patients is discussed. Summary Patients with hemorrhage, burns, and traumatic brain injury (TBI) may develop hypovolemic shock and require resu...
Cystic fibrosis is caused by mutations in the cystic fibrosis transmembrane conductance regulator (CFTR) gene that lead to abnormalities in transepithelial ion transport in the airways of affected pat...
