Rövid összefoglaló (regiszter, angolul)
This study is a prospective, observational study of patients aged 18-80 years with clinical diagnosis of bronchial asthma, allergic bronchopulmonary aspergillosis (ABPA), bronchiectasis and healthy subjects. Among them, the bronchial asthma group will be divided into asthma control group, asthma partial control group and asthma uncontrolled group according to the GINA asthma control classification. Record the baseline information of the subjects in detail, including basic information, disease course, smoking, previous acute attacks and hospitalizations, long-term medication, etc. (including the frequency, dose and duration of ICS use, antifungal drug type, dose, duration of use, and course of treatment), and evaluate and record environmental factors (such as indoor).Humidity, temperature, ventilation, pet keeping, plant planting, etc.) and other lifestyle factors that may affect disease control and fungal exposure. The patient's disease status was assessed using questionnaire scores. Sputum samples were taken at the time of enrollment.Set (asthma ABPA group uses sputum induction), pulmonary function test and bronchodilator test, FeNO measurement (asthma ABPA group only), blood routine test, Aspergillus-specific IgE and IgG detection, total immunoglobulin IgE, allergen detection, etc. Dust was collected indoors (bedrooms), outdoor (balconies) and on the surface of air conditioners or fans (if applicable) in the subject's living environment, and environmental data such as ambient temperature, humidity, and particulate matter concentration were recorded. 18S rRNA technology was used for sputum and dust fungus detection, and ELISA was used for asthmatitis symptomatic markers, which assess the impact of fungal infections on the disease. Follow-up for each subject 6 months, 6 months after enrollment, the patient's symptom changes, acute exacerbations/exacerbations, and prognosis were recorded, and relevant questionnaire scores were completed.
