Cystic fibrosis (CF) is an illness that makes the lungs clog up with sticky mucus. There is no cure and so treatments are used to help make the illness easier to live with. The treatment can take lots of time and can feel not very nice sometimes. When children with CF become teenagers they need to learn to take charge of their treatment. This can be difficult. Teenagers with CF want to fit in with friends and can become more upset about their illness. Their parents have to learn to let their child take charge of their illness which can be hard for parents. These issues can put strain on parent-child relationships and this can make it harder for teenagers to stick to their treatment plans. A parenting program (called Teen Triple P) has been shown to help teenagers with other illnesses (such as diabetes) to be able to stick to their treatment plans. Parents are given a booklet to work through at home which helps them to build on the skills they already have. It aims to help families to support positive parent-child relationships, to manage difficult teenage behaviours, and to teach new skills and behaviours. So far no one has done any research to see if this program helps families of teenagers with CF. This research would like to see if the Triple P program can help teenagers with CF stick to their treatment plan. Helping teenagers stick to their treatment plan will help them to live happier and healthier lives.
Insulin replacement therapy may be effective in breaking the cycle of protein catabolism, undernutrition and overall clinical deterioration in pre-diabetic, insulin insufficient CF youth because of its potent anabolic effect. A significant number of CF patients might benefit from this therapeutic approach with a substantial impact on morbidity and mortality.
Cirrhotic patients are patients with high morbidity and mortality, it is very important for determining the prognosis of these patients. The importance increases when these patients waiting for a liver transplant. The Model for End-Stage Liver Disease (MELD) is a reliable measure of mortality risk in patients with end-stage liver disease. It is used as a disease severity index to help prioritize allocation of organs for transplant. MELD uses the patient values for serum bilirubin, serum creatinine, and the international normalized ratio for prothrombin time (INR) to predict survival. Blood tests that we use today in daily practice to evaluate the coagulation system (PT, PTT) do not check actually the functioning of the system, but examine the level of clotting factors and therefore only verify that the side of Anticoagulant of the equation and not the side of the procoagulant . To examine the coagulation system function tests have been developed, One of them is the thrombin generation. The purpose of the trial is to determine whether thrombin generation test can be a prognostic indicator in patients cirrhosis.
The purpose of this study is to assess degree of hepatic fibrosis using multiparametric MRI for investigating difference between normal or early fibrosis and advanced fibrosis.
This study plans to learn more about the effect of oral antibiotics for an outpatient pulmonary exacerbation (respiratory illness) on sputum (mucus) bacterial infections, lung function, airway inflammation and quality of life. In this study subjects will perform pulmonary function tests, provide a sputum sample and complete a questionnaire at two separate clinic visits. If a subject is unable to cough up sputum in clinic he or she will be asked to breathe in a salt water solution to help cough up sputum. The first sputum sample will be obtained at the first visit (within 48 hours of starting antibiotics). Pulmonary function testing and the questionnaire will also be completed at this time. Subjects will complete a two week course of oral antibiotics at home. During these two weeks subjects will be asked to write down the times antibiotics are taken and airway clearance (vest treatment) is performed. Within one week of completing the antibiotic course subjects will return to clinic for a second visit. At that time a sputum sample will be obtained again and if subjects are unable to cough up sputum they will again be asked to breathe in salt water solution to help cough up sputum. Pulmonary function testing and the questionnaire will also be completed at this second visit. Sputum samples will be tested for infections with bacteria and viruses. Sputum samples will also be used to measure markers of airway inflammation (swelling). The investigators hypothesize that the use of two weeks of oral antibiotics for the treatment of a pulmonary exacerbation will result in a decrease in the amount of bacteria measured in sputum. Additionally the investigators hypothesize that treatment with antibiotics will lead to an improvement in lung function, a decrease in airway inflammation and an improvement in quality of life measurements.
The purpose of this study is to determine whether magnetic resonance imaging (MRI) using inhaled hyperpolarized 129Xe gas, and conventional contrast can help visualize impaired lung function and detect changes over time in patients receiving treatment as well as those who don't. 129Xe is a special type of xenon gas and when inhaled during MRI may be able to show areas of abnormal thickening of parts of the lungs. These images combined with images taken with injected contrast agents or other types of MRI may provide a better way to look at lung structure and function in patients with IPF. The ultimate goal is to predict how a particular patient might respond to a particular therapy and to observe such responses earlier than conventional tests. The investigators anticipate that the images acquired in this study will provide more specific information about lung disease than standard lung function tests. The use of 129Xe MRI is investigational. "Investigational" means that these tests have not yet been approved by the US Food and Drug Administration and are being tested in research studies like this one. In addition, standard MRI with contrast is not typically done as standard of care for monitoring progression of IPF, therefore, its use in this study is also considered investigational. Healthy volunteers are being asked to participate in this study because the investigators need to develop a database of functional images that are representative of healthy lungs.
This study assesses the tolerability of a single dose of gefapixant (AF-219) in participants with idiopathic pulmonary fibrosis (IPF). Six eligible participants will receive a single 150 mg dose of gefapixant and undergo tolerability and PK assessments.
identify and validate biomarkers that might reflect partial restoration of CFTR function and can be used to monitor disease progression, and ii) evaluate the mechanistic effects of CFTR modulators and other relevant therapies in individuals with CF
Chest/abdominal wall varices and spider nevi are two common presenting signs of liver cirrhosis. Their prognostic values remain unclear.
