Filter by:The purpose of this study is to see if giving people with CF and ABPA enough vitamin D to make their blood levels of the vitamin higher, will reduce the allergic response in their body and make the symptoms caused by ABPA better.
The purpose of this study is to assess the pharmacokinetics and safety of VX-809 and VX-770 alone and in combination in healthy subjects.
The purpose of this study is to investigate the pharmacokinetics and safety of a single dose of VX-770 in subjects with moderate hepatic impairment.
Cystic fibrosis is the most common inherited life limiting condition which affects children. Patients with it develop lung infections which become difficult to clear, and damage the lungs. These are treated with antibiotics (such as tobramycin) into the vein (termed "intravenous antibiotics"). This has without doubt improved survival. However, all treatments have side effects. Tobramycin can cause kidney damage. The investigators have preliminary data that suggests that administering tobramycin in the morning may be safer for the kidneys than administering it in the evening. The investigators plan to approach children and adults with cystic fibrosis whose doctors have decided to administer a course of intravenous tobramycin. The investigators will randomly allocate them to receive it at either 0800h or 2200h. The investigators will measure the rate at which the body eliminates tobramycin from the bloodstream, by measuring the amount of tobramycin in the blood stream after administering the antibiotic. For each patient the study will last for the duration of the course of antibiotics. This is decided by the doctor looking after the patient (rather than the researcher), and would typically be 14 days. The investigators will also measure substances in the blood and urine ("biomarkers") which are sensitive indicators of low levels of kidney injury. The investigators will monitor lung function and lung bacteria in both the groups to ensure that the patients in both groups improve by the same amount. If the preliminary data are proved correct, this research will allow investigators to improve the safety profile of tobramycin, one of the most widely prescribed drugs in cystic fibrosis.
Patients with Cystic Fibrosis have multiple pulmonary infections and repeated antibiotic treatment. These factors taken together with high sputum viscosity and slow motility of the gastrointestinal tract-may change the pathogenicity and consistency of the intestinal pathogens. Part of the pulmonary infections in CF patients are due to intestinal pathogens. A pilot study performed by the researchers using probiotics in CF patients showed a decrease in the rate of pulmonary infections. Therefore,we planned a double-blind placebo-controlled trial to examine the effect of probiotics on pulmonary infections, sputum bacteria and sputum inflammatory markers in CF patients.
The objective of the study is to implement a new method of performing chest CT imaging in young children with cystic fibrosis at Packard Children's Hospital. This technique will be used to evaluate early lung disease comparing quantitative chest CT air trapping and airway measurements with lung function measurements in infants, toddlers, and young children with chronic lung disease.
Cystic Fibrosis (CF), the most common inherited disease in Caucasians, is characterized by chronic pulmonary inflammation and progressive loss of gas exchange units that eventually results in respiratory failure. There is strong evidence that, in CF, abnormally low perfusion carries a high risk of death independent from the presence of pulmonary hypertension. However, the evolution of pulmonary vascular disease in CF and how it might contribute to the rate of decline in lung function is not known. Our knowledge remains limited to the results of old observational studies which concluded that the major causes of pulmonary vascular remodeling and hypertension in CF are hypoxic respiratory failure and destruction of lung tissue. Our recent data obtained by state-of-the-art Magnetic Resonance Imaging (MRI) of the pulmonary circulation, challenges the existing paradigm. We demonstrate that in the absence of hypoxia, significant changes in pulmonary perfusion and in surrogate measures of vascular resistance as well as in collateral blood flow begin early in the course of CF. Newly developed therapeutics have altered dramatically the course of patients suffering from pulmonary vascular disease. Through this 8 week trial, we will examine by Magnetic Resonance Imaging the effect of Sildenafil on pulmonary perfusion and systemic vascularization of the lungs in subjects with mild to moderate disease.
The primary objective of this study is to determine if quantitative Dynamic contrast-enhanced magnetic resonance (DCE MR) perfusion imaging accurately quantifies right and left pulmonary artery blood flow as compared with phase contrast flow velocity mapping (PC), the current gold standard of flow volume measurements.
Adolescents with cystic fibrosis are particularly vulnerable to poor adherence, which negatively impacts their health status, quality of life and long term survival. CFFONE: A Cell Phone Support Program for Adolescents with Cystic Fibrosis, will make use of cutting-edge technology- a broadband capable, cellular telephone keyed into a highly-interactive informational web site. This web site will provide engaging online learning activities and resources specific to adolescents with cystic fibrosis. We believe the information and activities contained in CFFONE will improve adolescents knowledge, attitudes, and practices around cystic fibrosis and that adolescents exposed to the CFFONE program will demonstrate an increase in adherence to their treatment regimens and related improvements in their health status and quality of life.
The purpose of this study is to evaluate the safety and tolerability of denufosol 60 mg TID in pediatric CF patients 2 to 4 years of age
