Retrospective Observational Study to Compare Cystic Fibrosis Patients in Two Decades Before and...
Cystic FibrosisThe purpose of this study is to describe two cohorts of cystic fibrosis patients treated in 2 different decades in terms of FEV1 (Forced Expiratory Volume in one second) maintenance.
Biodistribution of Neutrophile Proteases in the Sputum of Patients Affected by Cystic Fibrosis
Cystic FibrosisThe purpose of the proposed project is to characterize the neutrophile proteases which participate in the chronic inflammatory phenomenon associated with the cystic fibrosis and which are responsible for the degradation of the lung tissue. The respiratory failure which results from it is one of main causes of the fatal evolution of this pathology but the anti-inflammatory therapies based on the use of antiproteases targeting specifically the soluble elastase did not end, until now, in the hoped results. The identification of the other noxious targets is a crucial element to give new orientations to the anti-inflammatory strategies based on the administration of antiproteases which remain a promising way.
Aztreonam Lysine for Inhalation in Patients With Cystic Fibrosis and Pseudomonas Aeruginosa Airway...
Cystic FibrosisPseudomonas Aeruginosa Airway InfectionThe primary objective of this program is to provide expanded access to aztreonam lysine for inhalation (AZLI) 75 mg prior to its commercial availability to patients with cystic fibrosis (CF) and chronic P. aeruginosa airway infection who have limited treatment options and are at risk for disease progression.
A Study to Determine the Variability of a 6-Minute Walk Test in Cystic Fibrosis Subjects With Advanced...
Cystic FibrosisThis is an observational study to be conducted at approximately 25 sites in the United States. Approximately 25 subjects with severe obstructive CF lung disease (FVC <40% predicted) will be enrolled.
Can Quantitative Ultrasound be Used for the Evaluation of Bone Health in Adolescents and Adults...
Cystic FibrosisMeasurement of bone density of Cystic Fibrosis patients with two techniques and correlation to serum bone parameters, use of steroids, lung function and nutritional status.
Prevalence of Chronic Rhinosinusitis in Cystic Fibrosis
Cystic FibrosisSinusitisAim of the study is to detect the prevalence of chronic rhinosinusitis and the colonisation with Pseudomonas aerug. in the upper airways in patients with cystic fibrosis.
Cystic Fibrosis Treatment Adherence Cayston Proof-of-Concept Pilot Study
Cystic FibrosisReal-world adherence to inhaled and oral therapies for cystic fibrosis (CF) patients remains discouragingly low, ranging between 31-53% for inhaled antibiotics and 41-72% for hypertonic saline. Programs to enhance adherence, including comprehensive behavioral interventions with adolescents, have met with mixed success. Advances in therapy, treatment delivery systems, and data capture technology offer the potential for enhancing adherence by providing immediate and more frequent feedback to the patient regarding his or her fidelity to the prescribed treatment regimen. We propose to conduct a proof-of-concept study to evaluate a systematic approach to linking treatment and feedback components to enhance adherence.
Glucose Tolerance in Children With Cystic Fibrosis
Glucose IntoleranceCystic FibrosisThe aim is to describe the association of glucose tolerance measured with three different tools (continuous glucose measurement system - CGMS, oral glucose tolerance testing - OGTT and optional intravenous glucose tolerance testing -IVGTT) with parameters out of lung function and anthropometric parameters in patients with cystic fibrosis.
Evaluating the Impact of Chronic Rhinosinusitis on the Health-Related Quality of Life Among Adults...
Cystic FibrosisIndividuals with Cystic Fibrosis (CF) have a defective protein, which is known as the cystic-fibrosis transmembrane regulator (CFTR). The CFTR transports salt and hydrates mucous. CFTR defects may result in the accumulation of thick mucous in the sinus cavities. As a result, the tiny hair-like structures that sweep mucous out of the sinuses cannot function properly, which can lead to recurrent infection and swelling of the sinus walls. When symptoms are persistent for more than 12 weeks, this is known as chronic rhinosinusitis (CRS). The symptoms that are associated with CRS are nasal discharge, congestion, facial pain or pressure and reduced sense of smell. CRS in non-CF patients affects a large number of individuals in Canada and has been found to be associated with poor quality of life. In the CF population the life expectancy is increasing but chronic disease like CRS is becoming increasingly prevalent. Investigators currently do not know the impact that CRS has on the health-related quality of life in adults with CF and how many suffer from symptoms. The investigators aim to determine the impact of CRS among adults with CF, in order to gain a better understanding of chronic disease among these individuals. The investigators strongly feel this research will improve the referral processes between Respirologists and Otolaryngologists, thereby improving treatment and quality of life for patients.
IL-17 Neutrophils in CF Lung Inflammation
Cystic FibrosisThe purpose of this study is to determine whether IL-17 polymorphonuclear leukocytes (PMNs) are central to the disease pathology in CF. This will be determined by demonstrating that IL-17 PMNs are present in the CF airway, correlate with lung function measures, and decrease in patients being treated with IV antibiotics for a pulmonary exacerbation.
