Active clinical trials for "Cystic Fibrosis"

Ivacaftor will restore CFTR function in treated CF patients with the G551D mutation. Improvement in ventilation, salt balance and well-being will contribute to better exercise capacity at all levels of lung function. While potential improvements may be variable across the spectrum of lung function, even small gains at low levels of FEV1 may have significant benefit for some subjects.

Background to ghrelin Ghrelin is a naturally occurring hormone found in the blood which stimulates appetite. In healthy individuals, levels of ghrelin are high before a meal and falls afterwards. Previous studies have shown that giving ghrelin (by injection) to thin patients with renal failure and cancer increases their food intake. Furthermore, addition of ghrelin may also reduce inflammation within the body. Cystic Fibrosis (CF) is a genetic disease which frequently results in recurrent lung infections (leading to progressive inflammatory lung damage) and low body weight. Low body weight in CF is associated with increased lung infections, rapidly worsening lung function and a shortened life expectancy. The researchers postulate that administration of extra ghrelin to CF patients with low body weight may increase food intake and reduce lung inflammation. If successful, this study might identify ghrelin as a potential therapy for CF patients to improve nutrition, decrease lung inflammation and thereby improve survival.

Cystic fibrosis (CF) is a lung disease that affects 30,000 children and adults in the US. Incorporation of regular exercise into the lives of patients with CF is of interest because it may improve lung function and quality of life. Yoga is an activity that may benefit patients with CF in many ways including strengthening muscles of breathing, improving lung function, and reducing stress which could improve quality of life and adherence to therapies. Yoga has been shown to be beneficial in patients with other lung diseases such as asthma, but has not yet been studied in CF. The investigators hypothesize that yoga will be an activity that is safe and tolerable for CF patients 12 to 25 years of age. The primary aim is to investigate the safety and tolerability of an 8 week yoga program for patients with CF. The secondary aim is to determine the effect of yoga on many aspects of CF disease including respiratory symptoms, adherence to regular CF therapies, quality of life, lung function, exercise tolerance, and nutritional status. The long-term goal is to use the data obtained in this study to design a future study of the efficacy of yoga in a larger population of CF patients at multiple CF centers. This research has the potential to influence the prevention and treatment of CF by providing data which could be used to help understand the most appropriate and beneficial type of physical activity for CF patients.

The primary objectives: To evaluate the effect of immunonutrition on the adult patient suffering from cystic fibrosis Safety of immunonutrition The effect of immunonutrition on parameters of oxidative stress The effect of immunonutrition on the inflammatory parameters The effect of immunonutrition on nutrition status Hypothesis The high oxidative stress is present in patients with cystic fibrosis. Immunonutrition has been shown to positively modulate oxidative stress in the different clinical setting however it has not yet been evaluated inpatients with cystic fibrosis who frequently need some support by means of enteral nutrition. We anticipate that the substitution of routine enteral nutrition by immunonutrition will result in improving of oxidative stress parameters. ,

Cystic Fibrosis (CF) is a life limiting illness. Median predicted UK survival is 41.4 years (UK CF Registry 2011). The commonest cause of death is respiratory failure. Non invasive ventilation (NIV) is a system which delivers a preset pressure to supplement the size and depth of each breath. It is introduced in CF to manage established respiratory failure. A nose or a mask which covers both the nose and mouth allows flexible ventilation, is used just at night, or for part of the day in addition or for 24 hours as clinical status indicates. It is introduced within a normal ward environment and then continued longterm at home.Once respiratory failure is established longterm noninvasive ventilation is introduced throughout 24 hours and multidisciplinary assessment concludes that the timing is appropriate for the individual. This study aims to evaluate a potential development of current practice: the use of non invasive ventilation during hospital admission only to enhance recovery from an acute exacerbation which has caused respiratory failure in those individuals where long term non invasive ventilation is not yet indicated. A mixed methods design will allow description of the experience of noninvasive ventilation during a semistructured interview to add to understanding of the results from an experiment designed to measure the differences between noninvasive ventilation and standard care. Aim: To compare the clinical efficacy with the patient experience of NIV on recovery from an acute respiratory exacerbation complicated by respiratory failure in adult Cystic Fibrosis.

An airway clearance technique (ACT) is one of the core treatments for children with chronic lung diseases who are unable to clear their secretions effectively. Unfortunately adherence to performing an ACT is low with a reported rate between 40 - 70%. Up to the present, there has been no way to objectively measure adherence to an ACT. With new technology, it is now feasible to connect an electronic manometer to an airway clearance device to objectively measure how often the child is actually performing their ACT. The first part of this proposed study is to objectively measure adherence against reported adherence over a 4 month period. During the second 4 months a video game will be added to the digital manometer which only operates if participants are performing their ACT properly. Adherence will again be measured.

Malnutrition is a significant problem in children and adults with Cystic fibrosis (CF). An impaired intestinal digestion and absorption capacity is one of the main factors responsible for the malnutrition in CF. This impairment starts early in life, leading to malnutrition, muscle weakness, impaired immune and lung function associated with poor prognosis. As low BMI and body weight is strongly associated with morbidity and mortality, a reduction in weight loss in CF and its manifestations would save the healthcare system substantially per year. Simple methods to measure the digested portions and utilization of nutrients and the effectiveness of pancreatic enzyme preparations and medications in CF are not available. Developing a panel of methods to accurately measure gut digestion, absorption and function will lead to studies optimizing nutritional regimen and pancreatic enzyme replacement therapy in CF. Furthermore, it will provide detailed insight in the disease and age related mechanisms of gut dysfunction in CF. Finally, it will provide required information that will lead to implement new strategies to improve gut health in order to enhance nutritional status, quality of life and survival. The hypothesis is that intestinal macronutrient digestion, absorption and function in CF can be quantified by an innovative panel of methods using stable isotopes. With this panel of methods, information can be obtained on the effect of disease progression on lipid, protein and glucose digestion and absorption and on gut function in CF as well as in other diseases and conditions characterized by a compromised gut. Furthermore, the optimal nutritional regimen and pancreatic enzyme therapy if applicable can be evaluated in these diseases. In the present study the investigators will study: 1. Pediatric patients with CF at Arkansas Children's Hospital; 2. Adult patients with CF at University of Arkansas for Medical Sciences. 3. Healthy control subjects. Diagnosis of CF is made based on universal diagnostic criteria. All CF patients are characterized by abnormal lipid digestion based on clinical and or laboratory (72 hour fat analysis or fecal elastase measurement) diagnosis, and requiring pancreatic enzyme replacement therapy, and no presence of unstable metabolic diseases. Additional criteria for the CF pediatric inpatients are: admitted to ACH for treatment of exacerbations of CF disease, clinically stable. The CF outpatients are stable outpatients with pancreatic insufficiency.

Hypothesis 1: Mindfulness is a feasible tool for use within a cystic fibrosis (CF) clinic Hypothesis 2: Participants in the mindfulness intervention will show an increased level of quality of life post intervention with the Mindfulness course Hypothesis 3. Levels of mindfulness: Participants in the mindfulness intervention will report increased mindfulness levels post-program completion as compared to pre-program completion Hypothesis 4. Levels of stress: Participants in the mindfulness intervention will report lower levels of stress post-program completion as compared with pre-program commencement. Hypothesis 5. Levels of residual depressive symptoms post-mindfulness intervention program: Residual symptoms of depression are a risk factor for relapse of depression. Post -program participants of mindfulness will purport fewer residual depressive symptoms compared with pre-program. Hypothesis 6. CF is associated with severe neutrophilic inflammation of the airways. As mindfulness intervention has been shown to modulate immune system it may improve physical aspects of CF including markers of inflammation and markers of lung disease (lung function tests and rate of pulmonary exacerbations) and nutritional state.

This is a Phase 1/2a, multicenter study, designed to evaluate the pharmacokinetics, safety, and tolerability of once daily administration of 150 mg of Ciprofloxacin for Inhalation (CFI) in patients with Cystic Fibrosis who have a history of chronic P. aeruginosa lung infection.

Cystic fibrosis (CF) is the most common lethal autosomal recessive disease among Caucasians. While the pulmonary disease in CF receives most of the attention, gastrointestinal diseases occur in >95% of CF individuals and can contribute to significant morbidity, mortality and a decreased quality of life. The abdominal pain in CF is usual chronic in nature, and the etiology is not usually found, despite medical testing for standard causes of abdominal pain. Helicobacter pylori (Hp) is increasingly being recognized as the etiology of peptic ulcer disease and other upper and lower gastrointestinal tract diseases.1 The role that Hp plays in CF abdominal pain has not been elucidated. Our long-term goal is to understand relationship between chronic HP infection and abdominal pain in pediatric CF patients. The specific objective of this proposal is to utilize current state-of-the-art testing for HP to determine the prevalence of Hp in our CF patients age 5 and older. The central hypothesis is that Cystic fibrosis subjects with significant abdominal pain will have an increased incidence of Helicobacter pylori as determined by the urea breath test and stool antigen test. The rationale for the proposed research is that once we elucidate a causal relationship between CF patients with abdominal pain and Hp, we can begin treatment of this infection to improve quality of life.
