Filter by:This is a pilot study of inhaled antibiotic regimens is a pilot study examining clinical and laboratory endpoints of patients on inhaled antibiotic treatments. We hypothesize that alternation therapy utilizing Cayston and Tobi will inhibit antibiotic resistance and that alternation therapy will result in a decreased incidence of antibiotic resistance to Cystic Fibrosis (CF) microbial isolates. The long term strategic goal is to develop a model biometric system for selecting a patient's optimal inhaled antibiotic regimen by utilizing clinical and microbiological parameters.
The purpose of this study is to evaluate the long term safety and tolerability of Liposomal Amikacin for Inhalation (LAI) 590 mg once daily (QD) in Cystic Fibrosis patients with chronic infection due to pseudomonas aeruginosa. This long-term, open-label, multi-cycle extension study enrolled subjects who had successfully completed study TR02-108, were compliant with the study protocol, and did not meet any of the listed study discontinuation criteria. The safety and tolerability of LAI were evaluated for up to approximately 2 years.
A major factor in the respiratory health of Cystic Fibrosis (CF) participants is the prevalence of chronic Pseudomonas aeruginosa (Pa) infections. The Pa infection rate in CF patients increases with age and by age 18 years approximately 85% of CF patients in the US are infected. Liposomal amikacin for inhalation (Arikayce™) was developed as a possible treatment for chronic infection due to Pa in CF patients. The purpose of this study is to determine whether Arikayce™ is effective in treating chronic lung infections caused by Pa in CF participants. The effectiveness, safety, and tolerability of Arikayce™ will be compared to Tobramycin TOBI®, an inhalation antibiotic already available for use.
The purpose of this study to investigate the effect of sulforaphane from macerated broccoli sprouts in humans and to evaluate less invasive methods of assessing potential anti-inflammatory drugs in CF.
Given the treatment burden and excess morbidity and mortality associated with acute infective exacerbations in cystic fibrosis, a clear understanding of the mechanisms involved in the origins of an infective exacerbation and the response to antibiotics is vital to improving long-term outcomes in CF. This study will examine 3 areas of interest in CF exacerbations. 1. Bacterial biodiversity and its clinical significance 2. The role of bacteria which are able to rapidly mutate (hypermutators) 3. Inter-bacterial communication and its role in infective exacerbations Study Hypothesis 1 Increased microbiological diversity represents a balanced community of bacteria. The presence of a diverse population of bacteria in CF infections therefore predicts a better outcome for treatment than when a population consists of a small number of more virulent organisms. Study Hypothesis 2 Pseudomonas aeruginosa hypermutators can mutate much more often than ordinary Pseudomonas aeruginosa bacteria. Hypermutators are likely to grow better when the bacteria are under stress, such as during antibiotic treatment or during an infection. They are, however, weaker organisms because of the multiple mutations they have undergone. Their presence does not relate to clinical outcome but may be associated with the emergence of antibiotic resistance. Study Hypothesis 3 Some Pseudomonas aeruginosa bacteria communicate with each other by secreting and responding to chemicals known as quorum sensing (QS)molecules. As well as affecting the behaviour of bacteria, these QS molecules can cause inflammation in the lung of CF patients. Selective growth of QS-producing organisms can trigger lung exacerbations in CF. If antibiotics kill this population of bacteria and QS molecule levels drop in the lung, patients recover from infection quickly. Failure to kill these bacteria with antibiotics allow QS molecule levels to remain elevated and patients to have prolonged infections.
The purpose of this study is to determine if inhaled urea can be used to detect the presence of Pseudomonas Aeruginosa in the lungs
Previously, the investigators and others have shown that mucociliary clearance (MCC) is defective in patients with cystic fibrosis (CF) and it is now thought that alterations in airway mucus rheology figure prominently in the impairment. Mucociliary clearance works by trapping toxic particles, bacteria and viruses in the lung mucus and then quickly removing the mucus out of the lungs. Defects in MCC typically lead to the accumulation of mucus in the airways, and this in turn is associated with acute infections, chronic bacterial colonization and chronic inflammation. One treatment strategy that is gaining acceptance as an important therapy for improving MCC in adults with CF is the inhalation of the osmotic stimulus, hypertonic saline (HS). A number of studies have shown that acute inhalation of HS (7% saline) significantly improves MCC in adults with CF and results from a recent study indicate that two weeks of inhaling HS leads to a significant increase in MCC that is sustained for 8 hours post inhalation and is associated with significant improvements in FEV1, FVC and FEF25-75 values. Since MCC in patients with CF appears to be impaired by adulthood, any drug that disrupts or slows the impairment in childhood could prove enormously beneficial in the long-term prognosis of the disease. Nevertheless, no studies have been conducted to determine if HS treatment improves MCC in children with CF. This is most problematic for physicians who care for children with CF who have normal FEV1 and FVC values, since it is unclear if they should treat these children with HS or not. This research study is designed to begin to answer this question. The investigators hypothesize that acute inhalation of hypertonic saline (7%) will improve MCC in CF children with normal pulmonary function. Our hypothesis will be tested in a one-year clinical trial that will be randomized and placebo-controlled. Twelve children with CF who are 7-12 years old and have normal FEV1 and FVC values will participate. Our goal will be to compare MCC in these children on two study visits after acute inhalations of placebo (0.12% saline) or hypertonic saline (HS) (7% saline) aerosol. The investigators predict that MCC values after acute inhalation of 7% HS aerosol will be statistically significantly greater than after placebo inhalation.
To study the contribution of osteopathy on the reduction of pain in adult patients with cystic fibrosis
Main objective : This project aims to assess the educational needs of patients who received a lung transplantation or a simultaneous heart-lung transplantation for mucoviscidosis. Specific objectives : Evaluate the specific needs dependent on seniority transplantation : 3 to 6 months, 6 months to 2 years, more than 2 years after transplantation Secondary objectives : - Assess the state of health - Assess the knowledge - Assess gestural know-how - Assess the cognitive know-how - Assess the behaviour adopted in reality by the patient - Assess motivation psychosocial factors of : - self-efficacy and inefficiency - representation of obstacles, disadvantages of treatment - sense of control over their health - feeling of being supported by health professionals, by his close - representation of his responsibility to take care of his health, to follow his treatment, to be active about his treatment
Main objective : This project aims to have a better understanding of the influence of representations of patients with mucoviscidosis, their assistants and their medical persons in the choice of patients to accept or not lung transplantation. Specific objectives : 1. Identify the knowledge, representations, or feelings of patients which could constitute bridles or factors of motivation to use for transplantation. 2. Identify the knowledge, representations, or feelings of medical persons which could constitute bridles or factors of motivation to the "encouraging" proposal to patients of lung transplant. 3. Identify the knowledge, representations, or feelings of assistants which could constitute bridles or factors of motivation to the "encouragement" of lung transplantation at its close. 4. Identify the needs of patients, assistants and medical persons to successfully reduce these bridles to transplantation and increase the factors of motivation. 5. Compare the representations of patients, assistants and medical persons 6. Search representations associated with patients who refuse the transplantation and those who accept the transplantation
