Active clinical trials for "Bronchiectasis"

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.

A study of an educational intervention of primary care practice physicians to assist in the identification of patients who have Bronchiectasis and to assess the effectiveness of the specific didactic educational intervention targeting primary care physicians in the recognition of Bronchiectasis.

Pain mechanisms and their clinical impact in patients with bronchiectasis have not been investigated yet. The aim of the research is to assess the presence of central pain mechanisms in patients with bronchiectasis using the Quantitative Sensory Testing (QST) assumptions.

Bronchiectasis is a long-term lung condition where the airways become abnormally enlarged, leading to a build-up of mucus and inflammation that makes the lungs more susceptible to recurrent infection. Patients with bronchiectasis have subtle abnormalities in the way their airway cells respond to infection that are, in part, responsible for the development of their condition. At present there are no licensed treatments for bronchiectasis. This study will aim to characterise in depth some of these abnormalities with a view to future studies that will try to develop treatments that can directly target those abnormalities at a molecular level. Patients known to have bronchiectasis who have provided written informed consent will be enrolled alongside healthy volunteers and patients with chronic obstructive pulmonary disease and cystic fibrosis, for comparison. Participants will give a blood sample and have a bronchoscopy. This is a thin telescopic tube, passed through the nose or mouth, under sedation, into the airways that will allow a sample of bronchial epithelial cells to be taken. The main objective of the study is to achieve a greater understanding of some of the key biological processes/pathways and disease marker genes that play a role in the development of bronchiectasis. This is important because, at present, little is known about the underlying disease mechanisms and there are no licensed treatments for bronchiectasis. The investigator's hope this in-depth characterisation of specific bronchial epithelial cell abnormalities in bronchiectasis will shed light on novel targets for future drug discovery.

The measurement of markers in the expired breath condensate has proven to be a useful method for assessing and monitoring airway inflammation. The aim of this study is to determine the amounts of pH in the expired breath condensate of patients with bronchiectasis, and the relationship between pH and the severity of bronchiectasis.

Prevalence of dynamic hyperinflation and its relationship with functional exercise capacity will be evaluated in children with bronchiectasis.

In the literature, there are no studies evaluating COVID-19 phobia, quality of life, health anxiety, physical activity level and quality of sleep in patients with bronchiectasis during COVID-19 pandemic. The investigators will evaluate these parameters in patients with bronchiectasis and compare the findings of healthy individuals during COVID-19 pandemic

In this study we analyzed the overall survival for all newly diagnosed patients with non-cystic fibrosis bronchiectasis from June 2006 onwards. The investigators wanted to confirm the known risk factors such as age, gender, smoking history and Pseudomonas aeruginosa and evaluate the impact on survival of etiology, number of different bacteriological species in retrospective and prospective sputa, azithromycin use and presence/development of pulmonary hypertension.

Non-cystic fibrosis bronchiectasis patients (and controls) were recruited for the study. The investigators' aim was to study the relevance of clinical parameters in terms of underlying disease severity, proteolysis and inflammation in a diverse non-cystic fibrosis bronchiectasis population.

Gastric reflux into the oesophagus may further lung damage in respiratory disease. The proportion of adults with chronic lung disease and gastric reflux is unknown. Adults with this disease regularly complete physiotherapy but the contribution of physiotherapy to reflux is unknown. This study will measure gastric reflux in adults with chronic lung disease, using 24 hour acid monitoring. It is anticipated that approximately 50% of adults with chronic lung disease will have gastric reflux. After monitoring, the number of gastric reflux episodes will be calculated. The results will identify the extent of the gastric reflux problem in these patients and will enable appropriate medical treatment and modifications to physiotherapy, which may improve lung function and quality of life.
