Filter by:Primary Objective Our primary objective in this study is to evaluate satisfaction of hormonal contraception in this sample of women and to evaluate the impact that this hormonal contraceptive has on cystic fibrosis (CF) disease in women with regular menstrual cycles accompanied by cyclic exacerbations. We hypothesize: 1a) women with CF who perceive an overall benefit of hormonal contraception will be more satisfied than women with CF who do not perceive a benefit, 1b) women with CF who have cyclic exacerbations will have decreased Pseudomonas aeruginosa mucoidy conversion while using hormonal contraception, 1c) women with CF who have cyclic exacerbations will have improved patient-reported quality of life indices while on hormonal contraception, and 1d) women with CF who have cyclic exacerbations will have improvement in pulmonary function tests while on hormonal contraception. Secondary Objective We plan to secondarily evaluate the cervical mucus of women with CF at the time of ovulation and compare it to that of healthy controls. We hypothesize that women with CF have ovulatory cervical mucus similar to healthy peers.
The purpose of this study is to characterize bacterial diversity and richness in the sputum of cystic fibrosis patients treated with every-other-month TOBI™ Podhaler™ and continuous alternating therapy with TOBI™ Podhaler and colistimethate (Colistin).
The primary objective of this study is to determine the long-term safety and tolerability of ataluren in participants with nonsense mutation cystic fibrosis (nmCF) who completed participation in the double-blind study PTC124-GD-009-CF (NCT00803205), as assessed by adverse events and laboratory abnormalities. The secondary objective of this study includes the assessment of the efficacy of ataluren, as measured by forced expiratory volume in 1 second (FEV1) and pulmonary exacerbation rate, and other safety parameters (for example, 12-lead electrocardiogram [ECG] measurements, vital signs).
The purpose of this study is to determine whether the medical device "simeox" is safe in the treatment of respiratory diseases, in comparison with traditional physiotherapy.
To provide efficacy and safety data comparing two dosing schedules of Tobramycin Inhalation Powder (TIP) for the treatment of pulmonary Pseudomonas aeruginosa in patients with cystic fibrosis.
The hypothesis being tested is that inhibition of the enzyme known as elastase in the airways of patients with cystic fibrosis will help decrease the number of bacteria. Alpha1 antitrypsin, an elastase inhibitor, will be given to patients with cystic fibrosis by aerosol therapy twice in 1 day and sputum will be collected to measure the density of bacteria
This is a double-blind randomised controlled crossover study to investigate whether high frequency airflow oscillation (HFAO), delivered using Aerosure, improves sputum clearance in patients admitted to hospital with infective exacerbations of cystic fibrosis (CF). This study will test the hypothesis that the wet weight of sputum expectorated is greater following the use of Aerosure than following the use of a sham Aerosure device.
Cystic Fibrosis (CF) is a genetic disorder of altered ion transport across cell membranes which is characterised by the production of thickened bodily secretions, affecting the function of organs such as the pancreas and the lungs. Within the lungs, thickened sputum is very difficult to clear, which can results in recurrent chest infections, which can lead to lung damage. therefore it is important to optimise the removal of sputum to try and prevent these complications. Traditionally, a variety of approaches are usually combined including inhaled medications to thin or hydrate secretions, and chest physiotherapy to mobilise secretions and improve sputum clearance. There are many chest physiotherapy or airway clearance techniques (ACT) available including breathing methods such as the Active Cycle of Breathing Techniques (ACBT) or Autogenic Drainage (AD) and adjuncts such as Positive Expiratory Pressure (PEP), High Frequency Chest Oscillation (the "Vest"), or oscillatory devices such as the Flutter or Acapella. When people with CF have an infection or have severe disease often the effectiveness of ACTs can decrease due to fatigue, shortness of breath or having an overwhelming amount of sputum. At this time it is necessary to re-assess ACTs and the addition of positive pressure to airway clearance techniques has been shown to be helpful in decreasing fatigue during chest physiotherapy. At present no research studies have reported an increase in sputum cleared with the addition of positive pressure, however it is thought that the ability to take a deeper breath when using positive pressure would help to improve sputum clearance. With clinical experience of the use of NIV with adult CF patients, the investigators aim to explore this objectively in this study. Research Question: Does the addition of non-invasive ventilation (Breas, I-Sleep 25) as supplementary positive pressure to normal airway clearance techniques improve sputum clearance in stable adult patients with cystic fibrosis? Hypothesis The inclusion of non-invasive ventilation in addition to a patient's normal airway clearance technique will lead to improvements in subjective ease of clearance and work of breathing during airway clearance and objectively increase sputum clearance, as well as being well tolerated in patients as an adjunct to airway clearance.
Respiratory exacerbations are frequent among cystic fibrosis patients and supplemental oxygen is usually required. We will compare a new high flow nasal cannula system with Venturi masks for oxygen supplementation to patients with CF hospitalized for respiratory exacerbation.
This is a randomized, double-blind, cross-over, vehicle-controlled study to determine whether GS-5737 in 2.8% saline accelerates mucociliary clearance (MCC) in healthy subjects, compared to vehicle of 2.8% saline alone.
