Bronchiectasis Adult
Conditions
Brief summary
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.
Detailed description
Airflow limitation is common exist in idiopathic bronchiectasis patients. Our previous studies showed that FEV1\<50% is one of the major risk factors for poor prognosis and high incidence of acute exacerbation in patients with bronchiectasis. However, there are few evidence on the treatment of bronchodilator in bronchiectasis with airflow limitation, and there is no recommendation in bronchiectasis guidelines. Moreover, because of the high risk of infection and bacterial colonization in bronchiectasis, there is still unclear whether inhaled corticosteroids or bronchodilators affect the parameters of bronchiectasis. Thus, there is urgent need to optimize the treatment of bronchiectasis with airflow limitation.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Actue exacerbation | One year | Times of acute exacerbation |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Leicester Cough Questionnaire | Six months | Cough Questionnaire for the degree of cough. The minimum value is 1 and maximum value is 21. Higher scores mean a better outcome. |
| Questionnaire of life-Bronchiectasis | Six months | Including eight scales: respiratory symptoms; physical, role, emotional, and social functioning; vitality; health perceptions; and treatment burden. For each scale, scores are standardized on a 0-to-100-point scale; higher scores indicate better health-related quality of life. |
| FEV1, FVC | Six months | Forced Expiratory Volume In 1s and Forced Vital Capacity. |
| modified Medical Research Council score | Six months | modified Medical Research Council score for the degree of dyspnea. The minimum value is 0 and maximum value is 4. Higher scores mean a worse outcome. |
| Incidence of atrial fibrillation | Six months | One of common adverse events |
| Incidence of coronary artery disease | Six months | One of common adverse events |
| FEV1% | Six months | The percent of predicted Forced Expiratory Volume In 1s |
