It is to determine the effectiveness of pulmonary rehabilitation by telerehabilitation method in bronchiectasis patients. The cases meeting the inclusion criteria will be randomized and divided into two groups, the groups will be named as Telerehabilitation Exercise Group (TRGr) and Control Group (CGr).
The aim of this clinical trial is to assess the safety of: - single doses of the study drug CHF6333 in Healthy Volunteers (HVs) and in subjects with Bronchiectasis (BE) - Part I - repeated doses of the study drug CHF6333 in subjects with BE - Part II
BronchConnect is a prospective trial to investigate the impact of support groups on health care related quality of life in those with noncystic fibrosis bronchiectasis (NCFBE). It has been well demonstrated that participation in patient support groups improves quality of life in those who suffer from interstitial lung disease and chronic obstructive pulmonary disease, but the impact is largely unknown for those who live with NCFBE, a chronic lung disease with rising prevalence with no targeted FDA-approved therapy. NCFBE causes chronic cough, dyspnea, recurrent infections, and leads to anxiety and uncertainty. This study seeks to evaluate the impact of a virtual patient support group for patients with NCFBE through questionnaires to assess change of quality of life and anxiety, and exacerbation rates through clinical assessment.
This is the follow-up study of autologous transplantation of P63+ lung progenitor cells (LPCs) for treatment of bronchiectasis (NCT03655808). Bronchiectasis is the consequence of chronic suppurative inflammation and fibrosis of the bronchial tubes and the surrounding lung tissues. This seriously damages the muscular and elastic tissues of the bronchial walls, leading to deformation and permanent dilatation of the bronchial tubes. Histopathological damage to the patient's lungs is irremediable. However, there is no effective drug for rebuilding the damaged lung tissue structure, and thus cannot fully restore normal lung function. Lung progenitor cells, located in the basal position of the bronchial epithelium, express the P63 and Keratin-5 (KRT5) marker genes. These cells are active in division and migration, continuously generating new cells to replace other types of dead epithelial cells. They exhibit functional plasticity and can directly repair bronchial and alveolar structures. P63+ LPCs can be extracted by fibreoptic brushing and then isolated, purified and expanded on a large scale using appropriate methods. Currently, preclinical studies and some pilot clinical trials have shown that these cells can successfully repair damaged lungs, improve lung function and have a favourable safety profile. To further investigate the therapeutic mechanism of P63+ LPCs, RNA sequencing will be performed on the remaining LPCs previously transplanted back into the patients. Additionally, to confirm the existence of LPCs in the lung tissue of bronchiectasis patients, the pathological sections of lung tissue samples from patients who had received surgical resection of the lesions, will be subjected to fluorescence staining.
There is an intricate link between bronchiectasis and fungi. Patients with cystic fibrosis frequently manifest fungal sensitization and fungal colonization with Aspergillus fumigatus.6 Aspergillus species also has a cause-and-effect relationship with non-CF (cystic fibrosis) bronchiectasis.7, 8 In allergic bronchopulmonary aspergillosis (ABPA), Aspergillus is the cause of bronchiectasis. In contrast, in other causes of bronchiectasis, A fumigatus can theoretically promote allergic response, which may result in poor lung function, increase the risk of exacerbations, and even cause ABPA over time.9, 10 In a recent study, we found an overall prevalence of Aspergillus sensitization of 29.5% and the prevalence of chronic aspergillus infection was 76%.11 The prevalence of chronic aspergillus colonization in non-(tuberculosis) TB-non-CF fibrosis was 47.5% (49/103).11 By mechanism similar to chronic bacterial colonization, chronic aspergillus infection or aspergillus sensitization can increase the risk of bronchiectasis exacerbation. Therefore, eradication of A. fumigatus from the airways of patients with bronchiectasis would decrease the future risk of a bronchiectasis exacerbation. Notably, in ABPA, use of itraconazole and voriconazole reduce the exacerbations by reducing the fungal burden in the airways.12, 13 In this randomized trial, we will investigate whether treatment with oral itraconazole for six months would reduce the future risk of bronchiectasis exacerbation in patients with non-CF-non-ABPA bronchiectasis.
The goal of this observational study is to learn about the use of equipment to monitor health at home in participants who have non-cystic fibrosis bronchiectasis. The main question[s] it aims to answer are: - How acceptable participants find using home monitoring equipment. - To find out if the data collected from home monitoring can help to detect chest infections (exacerbations) before participants get symptoms they are aware of. Participants will be provided with - - a handheld spirometer to record FEV1 (lung function) - a Fitbit, or other compatible activity monitor, to record activity and heart rate - a saturation monitor that fits painlessly on the end of the finger to record oxygen levels - weighing scales to record weight - a mini freezer and pre-labelled sample containers to store a daily sputum sample. There is enough room in the freezers for samples to be brought to routine clinic visits. We will provide a cool bag and freezer packs for this. A courier collection of the samples can be arranged if necessary. Participants will be encouraged to perform lung function, activity and oxygen levels at least 4 x per week. Participants will be guided through how to set up and use each piece of equipment by the research team. The devices all connect to a smartphone app called Breathe RM (Remote Monitor,) which is free to download, via Bluetooth. Once set up using the home monitoring devices and adding notes to the app should take no more than 15 minutes per day. Participants will be asked to record in the app - - episodes of pulmonary exacerbation that require antibiotic treatment - their coughing and wellness scores daily
The investigators aim to develop a comprehensive patient registry of patients with non-CF bronchiectasis and/or Nontuberculosis Mycobacteria (NTM)
This project will use literature analysis, expert research, real-world data mining and other methods to investigate the current status of the application of antimicrobial aerosolized inhalation in healthcare institutions, combine expert recommendations and real-world data analysis results to explore potential risk points in the process of antimicrobial aerosolized drug delivery, and sort out the key points of drug use management in healthcare institutions and the key points of regulatory recommendations for healthcare institutions.
People with bronchiectasis are prone to Pseudomonas aeruginosa (PA) infections, which can become chronic and lead to increased death rates and disease severity. Studies from cystic fibrosis suggest that eradication therapy aimed at PA can successfully transition patients to a culture-negative status, providing long-term benefits. Current guidelines for managing bronchiectasis in adults recommend eradicating PA when it is first or newly isolated; however, there is a lack of randomized controlled trials supporting such recommendations. The researchers hypothesize that both oral ciprofloxacin combined with Tobramycin inhalation solution and Tobramycin inhalation solution alone are superior to no eradication (inhaled saline) in terms of the eradication rates of PA, defined as a negative sputum culture of PA at both 24 weeks and 36 weeks.
