Filter by:The investigators meant to establish a multi-centered bronchiectasis patient registry for Chinese bronchiectasis patients. This would be the first bronchiectasis registry in China. Patients with all kinds of bronchiectasis would be enrolled.
This is a randomized, cross-over, single-blind trial. Eligible patients will be randomly assigned to undergo either capsaicin or adenosine triphosphate (ATP) cough provocation test, followed by a washout period of 2 to 14 days. Participants will be crossed-over to undergo another cough provocation test. Patient would be under observation in the out-patient clinics for ~2 hours following the cough provocation tests in case of severe adverse events.
The purpose of this study is to Understand the prevalence of non-tuberculous mycobacterial(NTM) infections in the middle-aged and old women patients with bronchiectasis in Mainland China, and explore the characteristics of patients with bronchiectasis comorbid NTM.
The investigators aimed to compare the home-based Pulmonary Rehabilitation with the hospital-based pulmonary rehabilitation in terms of pulmonary rehabilitation efficiency in patient with bronchiectasis.
The objectives of this research grant are to determine the association of hypoxia with the severity of osteoporosis in the patients with bronchiectasis and whether the mechanism of inflammation is triggered by inflammasones, which makes it more prone to osteoporosis in patients with bronchiectasis.
This is a single centre exploratory study that aims to apply hyperpolarized xenon-129 (129Xe) magnetic resonance imaging (MRI) methods and measurements in individual patients with and without lung disease to better understand lung structure and function and evaluate response to therapy delivered as a part of clinical care.
Monitoring patients with chronic, inflammatory airways disease particularly in the early stages is hampered by the relative insensitivity of current outcome measures to detect subtle changes. Multiple breath washout is a potential sensitive test that is a useful readout of disease at these early stages but it lacks standardisation and knowledge of variability with reference to standard lung function measures. This is a Cross sectional and longitudinal observation study. The hypothesis is that multiple breath washout-derived indices will provide a robust signal of gas mixing inhomogeneity, correlating with conventional measures of airway disease severity. Multiple breath washout performed on different devices will generate indices which correlate but differ in value.
Introduction: Bronchiectasis is a chronic lung disease in which the underlying condition causes permanent damage to the conducting airways. Bronchiectasis is associated with considerable morbidity and poor quality of life. While cystic fibrosis (CF) is the most common cause of bronchiectasis in childhood, non-CF bronchiectasis is associated with a wide variety of disorders. CF bronchiectasis patients show reduced daily habitual physical activity and exercise capacity. Cardiopulmonary exercise test (CPET) is increasingly gaining importance in clinical medicine and considered the gold standard exercise test for assessing aerobic exercise capacity. The test objectively evaluates exercise physiological functions, may help assess morbidity and predict the outcome and mortality in different clinical circumstances and may serve as a basis for individualized exercise prescription within the limitation of the disease. Unlike CPET in CF, there is a paucity of data on exercise capacity using CPET in non- CF bronchiectasis patients, and on the implications of physical activity on non- CF bronchiectasis morbidity and mortality. Aim: To evaluate and compare exercise capacity in CF and non-CF bronchiectasis patients. Methods: This will be a cross-sectional retrospective/prospective study population. The retrospective study will include data analysis of patients that preformed CPET as part of their clinical evaluation. In the prospective study, patients that are scheduled to perform CPET as part of their clinical evaluation will sign (or legal guardian) informed consent prior to participation. Patients will be recruited from the exercise clinic at the Pediatric Pulmonary Institute at the Rappaport Children's Hospital. Inclusion criteria: 1. Children and adults (age >7 years, height >125cm), with CF and non CF bronchiectasis. 2. Completed a maximal CPET test according to accepted criteria; (maximal VO2 > 80% predicted, maximal heart rate > 80% predicted, acceptable RER (RER > 1.0 in children (under 18 years), RER > 1.05 for adults) or reaching a VO2 plateau..3. Evidence of bronchiectasis in computed tomography (CT). Exclusions criteria: preforming submaximal CPET, lack of data from the exercise test, exacerbation of patient's condition within three days before the exercise evaluation, relevant related chronic diseases that affecting test results.
Treatment based on syndrome differentiation is the essence of traditional Chinese Medicine(TCM) and forms the individualized treatment. N-of-1 trials may be a good clinical effect evaluation method for the individualized treatment of TCM. This study aims to compare: (1) the efficacy of syndrome differentiation(individualized decoction) with placebo, (2)the efficacy of syndrome differentiation(individualized decoction) with the same prescription minus heat-clearing Chinese herbs, for patients with stable bronchiectasis through N-of-1 trials.
This is the registry of control participants for patients with various respiratory diseases. We screened healthy volunteers who visited Seoul National Hospital Healthcare System Gangnam Center for routine health check-up, and enrolled patients who agree to participate in the study. The participants undergo baseline questionnaires, provide blood specimen and information of the results of health check-up. We will include participants as controls if they have no significant respiratory symptom and no significant radiographic abnormality. The data from this registry will be compared with those from other registry of various respiratory diseases
