Filter by:Bronchiectasis is a chronic respiratory disease characterized by permanent bronchiectasis.The incidence and prevalence of bronchiectasis have assumed continuously grows in global. Chest computed tomography (CT) remains the imaging standard for demonstrating cystic fibrosis (CF) airway structural disease in vivo. However, visual scoring systems as an outcome measure are time consuming, require training and lack high reproducibility. Our objective was to validate a fully automated artificial intelligence (AI)-driven scoring system of CF lung disease severity.
Chronic obstructive pulmonary disease (COPD) and bronchiectasis are common chronic respiratory diseases in China. COPD is characterized by irreversible lung function decline due to airway inflammation, emphysema and alveolar destruction. Bronchiectasis is characterized by permanent bronchiectasis, its main clinical symptoms are cough, dyspnea, hemoptysis and recurrent respiratory tract infections. The incidence and prevalence of bronchiectasis have assumed continuously grows in global. Airway microbiota, whose alterations play an important role in the occurrence and development of bronchiectasis, form a complex ecosystem interacted with host cells and various biotic and abiotic factors in the microenvironment. Additionally, mounting evidence suggests that the airway microbiome is associated with COPD phenotypes and endotypes, and that dysbiosis contributes to airway inflammation. However, the mechanisms remain poorly understood, owing to limited knowledge of microbial functional properties, metabolic activities and cross-talk with the host immune system. The investigators aim to collect sputum specimen and perform multi-omic analysis on patients with COPD and bronchiectasis in seven clinical centres in China.
To comprehensively evaluate the pulmonary rehabilitation (PR) outcomes of patients with chronic respiratory disease (CRD), and to screen biomarkers for predicting different PR outcomes of patients with CRD using metabolomics methods, and to build a prediction model.
To determine the effect of pulmonary rehabilitation on pulmonary function in non-chronic obstructive pulmonary disease patients.To determine the effect of pulmonary rehabilitation on health related quality of life in non-chronic obstructive pulmonary disease patients.Limited researches are available in non chronic obstructive pulmonary disease patients.
Bronchiectasis is characterized pathologically by permanent bronchial dilatation and airway inflammation. The pathogenesis of the disease and the inflammatory, infective and molecular drivers of disease progression are not fully understood. The concept of "treatable traits" was proposed as biomarker-directed approach, based on the recognition of clinical phenotype and endotypes, help to personalized treatment options. Airway microbiota, including bacteria, NTM and fungus, have important but different inflammatory process in bronchiectasis. Our study will provide a new concept that airway microbiota might involve in the airway and systemic inflammation, mucus hypersecretion, as well as the airway damage, remodeling, and frequent exacerbations in bronchiectasis, thus leading to the deterioration of disease severity. Bronchiectasis remains a major cause of respiratory morbidity and treatment is generally only partly successful. Our study will give more clues about the mechanisms on the inflammatory pathway and the probably different response among patients with different isolated microbiota from airways.
Bronchiectasis is a chronic respiratory disease characterized by permanent bronchiectasis.The incidence and prevalence of bronchiectasis have assumed continuously grows in global. Different from overseas, bronchiectasis is common disease in China. This study will collect data from the real-world bronchiectasis database and follow up for one year, describe the bronchiectasis exacerbation rate and proportions for frequent exacerbation, clinical features and prognosis of bronchiectasis exacerbation, the treatment pattern (when clinically stable) during follow-up period; and describe characteristics of bronchiectasis at baseline. This study will also explore potential baseline risk factors for bronchiectasis exacerbation during follow-up period.
The present study will aim to find out whether a home treatment in people with bronchiectasis consisting of a single daily session to facilitate expectoration (combining nebulization of hypertonic saline (HS) at 6% followed by airway clearance techniques) is at least as effective as performing two sessions per day following the same process in each of the sessions, during a period of 6 months.
The study hypothesis is that dilations of idiopathic bronchi are particularly common in French Polynesia, and that there are arguments in favour of an underlying genetic factor. The study will retrieve retrospective data in the history of bronchial dilation, patients' personal and family history, microbiological and scannographic data, and the latest cardio respiratory checkup.
The objective of this study was to assess whether the long-term use of oral An'Ningpai Enteric Soft Capsuleson (300 mg, three times daily, 12 months) might reduce the incidence of exacerbations and improve the quality of life in patients with Non-CF bronchiectasis.
Airflow limitation is common exist in idiopathic bronchiectasis patients. However, there are few evidence on the treatment of bronchodilator in bronchiectasis with airflow limitation. The efficacy and safety of dual bronchodilator in idiopathic bronchiectasis with airflow limitation are still unclear. Thus, the investigators conduct a multicenter, open-label randomized controlled trial to investigate the efficacy and safety of dual bronchodilator in idiopathic bronchiectasis with airflow limitation.
