Active clinical trials for "Cystic Fibrosis"

This study compares the lung clearance index (LCI) in cystic fibrosis and healthy children obtained with two different multiple breath nitrogen washout (MBWN2) devices. Each participants will perform the test (LCI) in duplicate on each device.

In the planned study, 60 patients with mild cystic fibrosis (CF) with and without the involvement of small airways (small airway disease - SAD) are to be compared with a historical control group matched in age and gender. During the first study visit subjects are asked to perform a pulmonary function test (spirometry, body plethysmography with helium, determination of "Trapped Air") and exhaled nitric oxide (eNO) and exhaled carbon monoxide (eCO) measurements will be done in exhaled air. In addition, a blood sample is drawn to describe inflammatory status. Sputum is induced as well. During the second study visit, a non-specific bronchial provocation test(methacholine PD20 FEV1) is performed. The aim of the study is to get a characterization of the bronchial and systemic inflammation (IL-1ß, IL-6, IL-8, IL-17, TNF-α, NFKB, and recognition structures like TLR2 and TLR4) in CF patients with and without the involvement of the small airways, which may point to new treatment strategies.

According to the U.S. CF Foundation Patient Registry, more than 25% of children and 40% of adults were treated with intravenous (IV) antibiotics for flares of lung disease in 2016. Medication for these flares is often delivered through a peripherally inserted central catheter (PICC). Case series have identified important complications of PICCs in CF patients such as blood clots and infection. The frequency of PICC-associated blood clots in CF patients ranges from 2 to 8%. Catheter-related complications may interfere with completion of therapy and lead to repeated procedures and other complex medical treatments. In some cases PICC complications may discourage patients from accepting future courses of IV antibiotics. Therefore, it is very important to identify patient- and device-related factors that are linked with more frequent complications and to figure out ways to reduce these risks. Proposed risk factors fall into several broad categories. First are catheter-related factors; second are patient factors; and third are catheter-management factors. To date, no multicenter trial has carefully studied PICC complications in a large group of adult and pediatric CF patients from the time each catheter is placed to when it is removed. The main purpose of this study is to see whether the investigators can identify important factors in each of the three categories (patient, catheter, and catheter management) that are linked to various complications.

This project is an attempt to understand how Orkambi treatment affects exercise capacity and the function of the arteries in CF patients who are homozygous F508del. Our goal is to perform the exercise and vascular measurements every 3 months after a patient starts taking Orkambi.

The aim of this study is to develop a reliable and valid instrument to measure symptom management (experience and / or management strategies) during exacerbation episodes in CF patients. For the development a sequential exploratory two phase mixed-method study will be applied. In a first step, up to 25 CF patients will be interviewed: approximately 15 CF patients who experienced at least one episode of exacerbation in the past year and approximately CF 10 patients who are currently experiencing an exacerbation. The latter group will be interviewed up to 3 times during and after the antibiotic treatment. The instruments initial item list will be developed on basis of the interviews. Up to five health professionals will rate the items' relevance. In a further step, items' clarity and relevance will be assessed by cognitive debriefing interviews with no more than 10 patients. In the last step (part III), the instrument's preliminary construct and concurrent validity and reliability will be tested in a larger sample up to 150 patients experiencing exacerbation. Patients will be asked to complete the newly developed questionnaires and a set of other questionnaires at one time point. For part III, ethic approval will be asked at a later date (2015).

The Impact of cystic fibrosis (CF) on psychological and emotional functioning has been the focus of several studies over the past 20 years. The results from a current meta-analysis indicated that depressed patients were three times more likely to be noncompliant with treatment recommendations than nondepressed patients with chronic illness. To date, most studies of the prevalence of psychiatric symptoms have been limited by small sample size; reliance on samples of convenience that are potentially biased in term of rates of symptomatology, and measures that contain legitimate symptoms that are part of the respondent's chronic disease. Estimating the prevalence of depression and anxiety has become important as new evidence indicates that these symptoms may have a significant impact on health outcomes, including adherence to medical treatments, utilization of health care services, and rates of morbidity and mortality. More depressive the symptoms are associated with poorer lung function, and that in the absence of depression, poor lung function is minimally associated with lower patient ratings of quality of life. The purpose of the current study is to estimate the regional, and if possible the national prevalence of depressive and anxious symptoms in children and adults with CF and parents caregivers. Patients with CF ages 14 to 17, and parents of children ages 14 to 17, will complete and depression/anxiety screening measure at a routine clinic visit. These will then be linked with demographic and medical variables reported to the CF registry and analyzed cross sectionally. Adults with CF ages 18 and older will also complete the depression / anxiety screening measure at a routine clinic visit. Efforts will be made to recruit a representative sample of patients from each clinic.

Elevated fecal calprotectin is a biomarker for intestinal inflammation in cystic fibrosis

We wish to measure the inspiratory flow and volumes generated by the subjects inhaling from a spirometer with a high resistance dry powder inhaler in series in subjects with cystic fibrosis.

Our general aim is to determine the prevalence of diabetic microvascular complications in CFRD patients with and without fasting hyperglycemia, and to explore whether the presence of these complications is related to diabetes or CF factors. This cross-sectional study will provide pilot data for a longitudinal study of diabetes complications in CF.

Background Chronic airway inflammation is present in cystic fibrosis. Non-invasive inflammometry may be useful in disease management. Objective We studied 1) the ability of fractional exhaled nitric oxide and inflammatory markers (acidity, nitrite, nitrate, hydrogen peroxide, 8-isoprostane, interferon-γ, tumor necrosis factor-α, interleukin-2,-4,-5,-10) in exhaled breath condensate, to discriminate between cystic fibrosis and control children, and, 2) the relationship of biomarkers with control and severity of cystic fibrosis. Methods In 98 children (48 cystic fibrosis / 50 controls), condensate was collected using a glass condenser. Exhaled nitric oxide was measured using the NIOX®.
