数据说明

Conditions: Cystic Fibrosis, Lung Diseases. Justification: Advances in therapies and patient care have led to dramatic improvements in CF survival. Consequently, CF patients are living longer with varying degrees of lung function impairment. Dyspnea is a commonly reported symptom in CF that adversely impacts quality of life. Recently, elexacaftor/tezacaftor/ivacaftor (Trikafta), a combination drug therapy, was approved by Health Canada for use in CF patients. Exercise capacity is an important outcome parameter in CF and is a strong predictor of disease prognosis including survival. Although previous research in patients on elexacaftor/tezacaftor/ivacaftor combination therapy reported improved respiratory symptoms and lung function, it remains uncertain as to whether this translates into improvements in exercise performance. Stressing the respiratory system to its physiologic limits through exercise might provide a more sensitive outcome measure to evaluate the response to cystic fibrosis transmembrane regulator (CFTR) modulator therapy. Studies on another CFTR modulator therapy combining lumacaftor and ivacaftor, have shown inconclusive results on exercise tolerance in patients with CF when evaluated using an incremental work rate exercise test protocol. However, a far more clinically and physiologically relevant protocol in evaluating treatment effects is to use constant work rate exercise tests and to evaluate dyspnea at standardized submaximal exercise times. Additionally, changes in body composition shown to result from CFTR modulator therapy may also have contributed to these inconclusive findings; however, body composition has not been evaluated in previous CFTR studies. Purpose: The purpose of this study is to determine the various factors that cause shortness of breath (or dyspnea) in patients with cystic fibrosis (CF) and to determine how treatment with Trikafta can manipulate these factors to improve shortness of breath and exercise capacity. Hypothesis: The investigators hypothesize that Trikafta w
