Filter by:This study will assess whether rhDNase treatment improves ventilation inhomogeneity as assessed by lung clearance index (LCI) in patients with cystic fibrosis (CF).
The purpose of this research study is to determine if multiple doses of two inhaled drugs will help Cystic Fibrosis patients whose lungs are infected with a bacteria called Burkholderia dolosa. The names of these drugs are tobramycin solution for inhalation and amiloride solution for inhalation. Currently, treating patients with Burkholderia dolosa infections is challenging because the bacteria is resistant to antibiotics. Therefore, researchers are looking for drugs which, when taken with an antibiotic, will help the antibiotic to work more effectively.
The aim of this research study is to collect and store the specimens that are left over after patients undergo tests ordered by their physicians. These specimens will be used at a later time by researchers in the Pulmonary Division to develop a better understanding of pulmonary diseases or for the development of new treatments. Typical research studies that will be conducted on the stored tissue, fluid, or bacteria from the patient sample involve obtaining bacterial cultures, measurement of inflammatory markers, and examination of the characteristics of the tissue. Other similar tests may be done in the future; however, these tests have not all been determined at this time. It is important to note that no genetic testing will be performed on any samples that are obtained as part of this protocol.
This is an open-label pilot study of the safety and tolerability of 7% hypertonic saline inhaled twice daily for 14 days in infants with CF, 12 to 30 months of age.
The objective of this overall project is to develop a new aerosol-based technique for quantifying liquid absorption in the airways of subjects with cystic fibrosis(CF) that can be used to help develop new therapies. In CF, mutations in the CF gene result in dysfunction of the Cystic Fibrosis Transmembrane Conductance Regulator (CFTR) ion channel on the cells that line the airway epithelium, causing improper fluxes of ions such as sodium, chloride, and bicarbonate. The so called "low volume" hypothesis of CF pathogenesis contends that abnormal absorption of ions from the airways causes excessive absorption of liquid, resulting in an airway surface liquid layer that is dehydrated and difficult to clear. Here we are measuring the absorption rate of a radiolabeled small molecule (DTPA) from the lungs of cystic fibrosis patients and healthy controls. We hypothesize that the molecule will absorb more quickly in cystic fibrosis patients. Further studies will be performed to determine if DTPA absorption is related to liquid absorption in the airways.
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 miglustat on CFTR function in cystic fibrosis patients.
Rhinosinusitis disorders are often associated with Cystic Fibrosis. They can restrict quality of life enormously and give cause to repeated ENT surgery. The basic defect in CF is a dysfunction of chloride channels in exocrine glands, leading to retention of secretions and consecutive chronic inflammation with bacterial superinfections. The prospective placebo controlled cross-over study aims at the evaluation of a nasally inhalation of Pulmozyme with respect to mucus retention and resulting inflammation.
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.
