Filter by:The investigators research question is whether or not yoga effectively alleviates symptoms of pain, sleep disturbance, anxiety and depression in children with cystic fibrosis. If yoga does prove to be effective, the investigators will educate our CF population about the benefits they may experience if they choose to incorporate yoga into their CF therapy. The investigators will also go on to do further research of other complementary alternative medicine therapies. This is a pre/post-test study with 20 subjects. The subjects will serve as their own controls. Each subject will participate in six yoga sessions over a ten week period. Subjects' symptoms will be evaluated with the use of questionnaires. The investigators will also test cortisol levels on weeks -2, -1, 1, 6, 7, 8. Cortisol is a hormone that is affected by stress. Testing of cortisol throughout the study will help us determine the subjects' stress level throughout the study.
Patients with cystic fibrosis (CF) suffer from chronic infections of the lower respiratory tract that can be caused by one or multiple bacteria, including Pseudomonas aeruginosa, which has been particularly problematic to eradicate and been implicated as the major cause of morbidity and mortality in CF patients. Aerosol delivery of antibiotics directly to the lung increases the local concentrations of antibiotic at the site of infection resulting in improved antimicrobial effects compared to systemic administration. Decreased efficacy, intolerance and high treatment burden with currently available therapies indicate a need for additional therapies. MP-376 (Aeroquin™) is a novel formulation of the fluoroquinolone levofloxacin that has been optimized for aerosol delivery. Preclinical and clinical studies conducted to date show that aerosol doses of MP-376 are safe and well tolerated, exert an antimicrobial effect, improve lung function and reduce the need for other anti-pseudomonal antibiotics. High concentrations of levofloxacin in the lung delivered as MP-376 are active against CF pathogens including those with high minimum inhibitory concentration (MIC) levels to aminoglycosides such as tobramycin (TOBI®) and other inhaled antimicrobial agents. Inhaled MP-376 can be delivered rapidly and efficiently using a customized PARI investigational configuration of the eFlow® nebulizer system.
To date, there have been no formal clinical studies completed using tiotropium in CF patients. While there is a large body of evidence demonstrating the efficacy and safety of tiotropium in patients with Chronic Obstructive Pulmonary Disease (COPD), relatively little is known about its efficacy and safety in patients with a diagnosis of cystic fibrosis. Therefore, Boehringer Ingelheim proposed to profile the long acting anticholinergic tiotropium and to generate adequate clinical data for use as a bronchodilator in paediatric and adult CF. The phase III trial (205.438) is a part of the approved Paediatric Investigation Plan (PIP) agreed for Spiriva® Respimat® in Cystic Fibrosis.
Malnutrition, including muscle wasting commonly occurs in children with cystic fibrosis (CF), negatively influencing their quality of life and survival. At the time of a diagnosis of CF, severe protein deficits can already be present. It is important to get CF children fed adequately to prevent that their condition becomes worse or that recovery takes longer. Oral supplementation trials showed that gains in lean body mass are difficult to achieve in CF unless specific metabolic abnormalities are targeted. However, the specific needs for certain food components are not clear yet in children that are ill. Therefore, more information is necessary on the need for protein and certain amino acids in children with CF. Previous studies support the concept of essential amino acids (EAA) as an anabolic stimulus in the young and elderly and in insulin resistant states. Until yet no information is present on the anabolic effects of EAA in CF. It is therefore our hypothesis that a high-leucine essential amino acids mixture specifically designed to stimulate protein anabolism will target the metabolic alterations of pediatric subjects with CF. In the present proposal, the acute metabolic effects of this high leucine essential amino acids mixture will be examined in pediatric subjects with CF and compared to that of a regular balanced total mixture of essential and non-essential amino acids. The principal endpoints will be the extent of stimulation of whole body protein synthesis as this is the principal mechanism by which either amino acid or protein intake causes muscle anabolism, and the reduction in endogenous protein breakdown. Both endpoints will be assessed by isotope methodology which is thought to be the reference method.
Cystic Fibrosis (CF) is caused by mutations in the cystic fibrosis transmembrane conductance regulator (CFTR) gene. The encoded protein, CFTR, is an epithelial chloride ion channel responsible for aiding in the regulation of salt and water absorption and secretion in various tissues. Although the disease affects multiple organs, the leading cause of mortality is the progressive loss of lung function. Obstruction of airways with thick mucus, chronic bacterial infection of the airways, and inflammatory response are all thought to play a role in causing lung damage. Through its function as a chloride channel, CFTR is believed to be integral in epithelial ion and water transport and hence, maintaining the normal hydration of lung secretions. VX-770 (ivacaftor) is a potent and selective potentiator of wild-type, G551D, F508del, and R117H forms of human CFTR. Based on in vitro studies and pharmacologic, pharmacokinetic (PK), and safety profiles, VX-770 has been selected for clinical development as a possible treatment for patients with CF. Hyperpolarized noble gas magnetic resonance imaging (HG-MRI) is a promising new means of assessing lung function by direct imaging of certain non-radioactive isotopes of an inert noble gas, such as helium or xenon. Through this technique, high-resolution 3-dimensional images of lung ventilation can be obtained in both pediatric and adult patients during a single short breath-hold following inhalation of the gas. This is a 2-part study to evaluate the effect of VX-770 on hyperpolarized helium-3 magnetic resonance imaging (3He-MRI), and to evaluate the safety and efficacy of VX-770 in subjects aged 12 years and older with CF who have the G551D-CFTR mutation. Part A is a single-blind, placebo-controlled study that includes 4 weeks of VX-770 treatment and 4 weeks of placebo treatment. Part B is an open-label, 48 week study of long-term effect of VX 770 on hyperpolarized 3He-MRI.
Meropenem is an intravenous antibiotic commonly used to treat acute exacerbation of respiratory infections in cystic fibrosis. The research study aims to determine if a different method of infusing the drug over 3 hours or longer, instead of the traditional half-hour will improve target attainment of drug concentrations and bactericidal activity. A secondary aim is to assess if the pharmacokinetics of meropenem is different during active infection compared to non-infective stage. Twelve patients admitted with acute respiratory infection and who requires meropenem will be enrolled into the study. Meropenem blood concentrations collected over 8 hours will be measured after half-hour and 3-hour infusions on different days. A pharmacokinetic modelling and Monte Carlo simulation program will use the data to assess and predict the optimal method of dosing. When patients return for a follow-up clinic visit, a single dose of meropenem will be administered and blood concentrations will be measured to determine the pharmacokinetics during non-infective stage.
The hypothesis is that the intranasal use of Pulmozyme will decrease the severity of sinusitis in Cystic Fibrosis and lead to an improved quality of life.
The objective of this study is to compare the lower airways inflammatory response to infection/pulmonary exacerbation among children known to have Primary Ciliary Dyskinesia (PCD) with children known to have Cystic Fibrosis (CF) as measured by the presence of inflammatory mediators in expectorated/induced sputum.
The objective of this study is to evaluate the effects of VX-770 on Desipramine
Cystic fibrosis (CF) is the most common lethal, inherited disorder among Caucasians. Choline is an essential vitamin and as a methyl donor is critically needed to support the normal metabolism. Our previous studies have demonstrated that children with CF have depleted levels of choline. The purpose of this study is to gather data on the status of choline and related metabolites in children with Cystic Fibrosis by age and gender. The hypothesis for this study is that in children with CF, deficiency of choline and related metabolites will increase with increasing age.
