Filter by:Inflammation clearly contributes to the progression of the cystic fibrosis (CF) lung disease, and administration of the anti-inflammatory agent high-dose ibuprofen retards the rate of decline of pulmonary function. However, utilization of this valuable drug has been suboptimal because of its rare, but dramatic, adverse effects. Therefore, alternative anti-inflammatory agents are urgently needed. One strategy for identifying new anti-inflammatory agents is to determine the mechanism by which the only proven anti-inflammatory agent for the CF lung disease, high-dose ibuprofen, exerts its effect. If this were known, then other drugs that act by a similar mechanism become candidates for treating the CF inflammatory disease. The investigators have shown, in our preliminary studies, that high dose ibuprofen limits the delivery of neutrophils to an inflamed mucosal surface, the gingival crevices. The investigators plan to test pioglitazone and simvastatin, (ibuprofen (positive control)) to determine their anti inflammatory affects on neutrophil migration to the oral mucosa. The hypothesis to be tested is that pioglitazone, and/or simvastatin will reduce neutrophils in the oral mucosa after 10 days of therapy in mouthwashes of healthy volunteers. Ibuprofen will be used as a positive control. This study will provide pilot data from healthy volunteers to support an FDA Grant to be submitted at a future date.
It is well known that an association exists between the acquisition of some respiratory pathogens and prognosis of CF people. About 57 % of patients has a lung infection due to P.aeruginosa (PA). Transmission of PA between CF patients is possible and several prevention measures are recommended. Among these measures, all international guidelines recommend that CF people maintain a minimum distance of 1 meter between them. However, this recommendation is not supported by specific studies and scientific evidence. In other words, the investigators don't know if this measure is sufficient or excessive, as it is based only on a theoretical rationale. This study aims at measuring experimentally the distance that can be reached by PA emitted from airways of colonized CF patients during cough and during conversation. To this purpose, the investigators will evacuate the presence of PA on surfaces placed at 4 different distances from patients, through the collection of 8 swabs, 4 of which following cough and 4 following conversation. Swabs will be collected on sterile surfaces comprised between tra 0 - 0,5 mt; 0,5 -1,00 mt.; 1,00 - 1,5 mt and 1.5-2 mt. All the PA-positive CF patients of the CF Centre of Tuscany aged 14 or more will be recruited.
The hypothesis of this study is that feeding infants diagnosed with CF via newborn screening a formula enhanced with a specific fish-oil fatty acid known as DHA will improve growth and decrease pancreatic dysfunction (as measured by human fecal elastase-1 in stool) over the first year of life. Briefly, infants diagnosed with CF in the first month of life whose parents chose not to breast feed their babies will be invited to enroll in a study comparing a standard commercial infant formula (Enfamil) with a formula enriched with arachidonic acid (AA) and docosahexaenoic acid (DHA). The study formula has 3 times the amount of DHA available in commercially available formulas. Infants will have monthly tests of stool elastase and blood work at entry, 3, 6, 9 and 12 months of age.
This clinical trial will attempt to determine whether we can improve clinical outcomes for patients with cystic fibrosis who are infected with a fungus called Aspergillus fumigatus.
Our data indicate that the CFTR-molecule functions as a transporter for sphingosine-1-phosphate and sphingosine or regulates the uptake of these sphingolipids by epithelial cells. The disturbed uptake of sphingosine and sphingosine-1-phosphate over the cell membrane results in an accumulation of ceramide in the cell membrane, which finally triggers a pro-inflammatory and pro-apoptotic status in the respiratory tract of cystic fibrosis patients. Amitriptyline reduces the cera-mide levels in the lung tissue, normalises the activity of cytokines and prevents constitutive cell death of epithelial cells observed in CFTR-deficient mice. Most important, amitriptyline prevents pulmonary infections of CFTR-deficient mice with P. aeruginosa. These effects of amitriptyline may result in an improved lung function of cystic fibrosis patients.
This is a Phase III, multicenter, open-label study, that will evaluate the improvement of nutrient absorption when participants will receive Ultrase® MT20. This study is sponsored by Aptalis (formerly Axcan). This study is performed in children from 7 to 11 years old.
This study will assess the effect of pancrelipase delayed release 24,000 unit capsules on fat and nitrogen absorption in subjects with PEI due to Cystic Fibrosis.
This study will investigate the safety, tolerability, pharmacokinetic, and pharmacodynamic response of patients with cystic fibrosis to administration of QAU145 via intranasal spray.
The majority of cystic fibrosis (CF) patients die from a progressive pulmonary disease.Airway inflammation plays a major role for the pathogenesis of CF lung disease, and ultimately leads to lung destruction. The release of oxidants during the inflammation process leads to a chronic imbalance of oxidants and antioxidants and may be a central component leading to irreversible lung damage in CF patients. The antioxidant glutathione, which is a naturally occurring tripeptide, is depleted in the extracellular epithelial lining fluid of the CF lung. The elevation of reduced level to normal and also the augmentation of glutathione concentrations above the normal level, as observed in smokers and during defence of Pseudomonas infection, may be desirable to avoid lung damage. Data from pilot studies in humans and animals have indicated that the glutathione concentrations in epithelial lining fluid can be elevated by aerosol application. The main objective of this trial is to evaluate the effect of a 24-week treatment with inhaled glutathione compared with control inhalations (normal saline) on pulmonary function in adult and pediatric CF patients. Secondary objectives are to determine the effects of inhaled glutathione on inflammatory variables, glutathione levels and free elastase in induced sputum and to evaluate the safety and tolerability of the 24-week treatment with inhaled GSH. There is considerable hope within the CF community that the addition of anti-oxidative therapy to an already comprehensive program for treating the lungs will decrease morbidity and improve the quality of life for patients with CF.
This is a research study where researchers are collecting blood to evaluate the genetic characteristics of individuals with chronic lung diseases, including asthma, COPD (chronic obstructive pulmonary disease), interstitial lung disease, cystic fibrosis, and lung cancer. The investigators hope to be able to identify an association between a genetic make-up in the blood samples and the risks of developing a particular lung disease, or severity of a lung disease. The findings of this study might be important to develop future preventative methods and potential treatments for the management of lung disease.
