Feasibility of Home-based Exercise Program for Adults With Cystic Fibrosis
Cystic FibrosisThe main objective of this clinical pilot study is to evaluate the feasibility and impact of a home-based exercise program on clinical and patient-centered outcomes in adult with cystic fibrosis (CF) and inform the design of a larger clinical trial.

Evaluating Bronchodilator Response in Patients With Bronchiectasis
BronchiectasisCystic Fibrosis3 moreAlthough patients with bronchiectasis tend to have non reversible obstructive patterns on pulmonary function tests (PFTs), reversible obstruction is not uncommon. While bronchodilator response (BDR) is a main characteristic of asthma, the pathophysiology causing this phenomenon in bronchiectasis patients is less clear. The goal of this clinical trial is to assess BDR in patients with bronchiectasis. The main aims of this study: To evaluate the role of bronchodilators in BDR testing of patients with bronchiectasis. Characterize and compare BDR between different subgroups of patients with bronchiectasis, and compared to patients without bronchiectasis (healthy controls). Identify demographics and other clinical variables associated with positive BDR Participants will be taking a series of three spirometry tests: After the first spirometry testing, patients will be randomly assigned to receive bronchodilators as per bronchodilator response protocol (Salbutamol, 100 mcg, 4 puffs via spacer) or four puffs of placebo. After a waiting time of 15 minutes, spirometry will be repeated. Following the second spirometry testing those who received salbutamol will now receive placebo and those receiving placebo will receive Salbutamol. After a second period of 15 minutes, a third series of spirometry will be recorded.

Cystic Fibrosis in the Kidney: Monitoring the Effectiveness of Elexacaftor/Tezacaftor/Ivacaftor...
Cystic Fibrosis (CF)CFTR Gene MutationIn cystic fibrosis (CF) renal base excretion is impaired, due to mutations in the Cystic Fibrosis Transmembrane Regulator (CFTR) gene, since CFTR function is crucial in regulation of the kidney's HCO3- excretion. The investigators suggest that challenged urine HCO3- excretion is a biomarker of CFTR function, which can be used to evaluate the extent of CFTR dysfunction and the possible correcting effects of CFTR modulating therapy. This study aims to evaluate changes in challenged urine HCO3- excretion in CF patients, who are currently in treatment with the triple CFTR modulator combination therapy, Elexacaftor/tezacaftor/ivacaftor (ETI), before, during, and after a short treatment pause.

Project 2 Airway Potential Hydrogen (pH) in Asthma
Cystic FibrosisAsthma2 moreThis study is testing a non invasive way to measure airway pH in individuals with Asthma and Cystic Fibrosis using a new inhaled drug. The airway pH will help health care providers in creating tailored treatment plans for individuals suffering from these specific conditions.

NETwork of Linoleic Acid Supplementation in Cystic Fibrosis
Cystic FibrosisUndernutrition is a common problem in patients with cystic fibrosis (CF) despite international consensus that the patients shall be given 120-200% of energy recommendations. Studies imply that one problem might be that the patients are not compensated for the essential fatty acid deficiency (linoleic acid, LA), which is well known in these patients. This deficiency is shown not to be due to fat malabsorption, but related to an increased turnover of arachidonic acid, a transformation product of LA. This abnormality is related to mutations associated with a more severe clinical phenotype. The most common and typical symptom of LA deficiency is poor growth. Studies in animals have further indicated that many of the symptoms in CF are related to the deficiency. A series of recent prospective studies from Wisconsin corroborate the importance of LA for growth. In Sweden LA has been supplemented to most patients since the late 70´, and the condition of patients have been among the leading in the world regarding growth, pulmonary function and survival. Short-term studies have shown better effect of LA supplementation compared to similar supply of energy without including extra LA. There are few long-term studies, performed before the gene was identified, giving very heterogeneous patient groups in regard to genotype, but with some positive results on growth and physiology. It´s of interest that modern personalized extremely expensive therapy with correctors and potentiators for Cystic Fibrosis Transmembrane Conductance Regulator may influence lipid metabolism. LA might thus tentatively be a cheap adjuvant to this modern therapy, but this has to be specially studied. The aim of the study is to find if there are differences in clinical and metabolic outcome between two groups, blindly given similar amount of extra calories, in one group consisting of linoleic acid.The benefit for the patients would be great if the expected positive effect can be proved in the planned study. The treatment will be cheap and without adverse effects. From socioeconomic point of view is would be a great advantage.
