Filter by: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.
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.
The aim of the study is to compare the efficacy of using EFA technology versus the combination of EFA + high flow in hypersecretory patients COPD and bronchiectasis
Introduction: Non-CF, non-PCD bronchiectasis in children is a chronic, suppurative lung disease diagnosed by high resolution computed tomography (HRCT) imaging of the lungs. Spirometry can be abnormal in bronchiectasis but has been shown to be insensitive to early disease in other related conditions such as cystic fibrosis. Lung clearance index (LCI) could have a role in assessment of the disease. Lung clearance index is calculated from multiple breath washout tests. There are limited data on the normative values expected using some devices, in a range of ages, and between ethnic groups. The investigators aim to establish normative values in children aged between 6 years and 12 years, to investigate differences between ethnic groups, and to establish the relationship between lung clearance index and other measures of disease in children with bronchiectasis. Methods: Healthy children will be recruited from a range of settings and reviewed to ensure no previous lung disease. Children with bronchiectasis diagnosed on HRCT will be recruited from the outpatient service of Birmingham Children's Hospital. All participants will perform lung function tests including LCI and spirometry. Basic demographic data was collected.
Smoking cessation support is provided by smoking cessation outpatient clinics in our country. Smokers with chronic airway diseases can also apply to these services by making an appointment from quit lines. Quit rates of that group patients were found to be similar to the general population. In novel smoking cessation support approaches immediate cessation support is reported to be more effective than routine practice. The sample in these studies consists of individuals who applied for lung health screening programmes. There is no study in the literature examining the effect of this immediate support on patients with chronic airway diseases' quit success. Our aim with this study is to examine impact of immediate cessation support by getting an appointment to the same cessation clinic instantly on our sample's cessation success.
Double-blind, randomized, cross-over trial involving 20 participants with bronchiectasis. This trial will make an important contribution to therapeutic development in bronchiectasis by determining whether alpha-1 antitrypsin (AAT) therapy results in reduced airway inflammation and improves neutrophil function. Patients will be randomly assigned to receive Prolastin-C 120mg/kg (n=10 patients) by weekly intravenous infusions, Prolastin-C 180mg/kg (n=10 patients) by weekly intravenous infusions or placebo (0.9% saline) for a period of 4 weeks, followed by a 3-5 week washout period and a further 4 weeks during which patients will cross-over to receive the alternative therapy.
To investigate the Influence of Climatic and Environmental Factors on Respiratory or Allergic Diseases in Sanya.
The bronchodilators (BD) have been widely used in bronchiectasis (BCE) therapeutic and have been shown to be effective in improving exercise capacity in patients with chronic obstructive pulmonary disease and asthma. However the BD effect on the exercise capacity of patients with BCE is poorly known. Besides, the respiratory mechanics pattern of the patients with BCE is not known nor its association with their physical activity level (PAL). Therefore, the hypothesis of this study is that BD are effective in improving exercise capacity of patients with BCE. The authors also propose to characterize the respiratory mechanics of the patients with BCE and to evaluate their PAL and its association with quality of life, as secondary aims.
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.
