- Henan University of Traditional Chinese Medicine
- Brief Summary
The aim of this study is to evaluate the effectiveness of Traditional Chinese Medicine (TCM) on patients with clinically stable bronchiectasis by a multi-center, randomized, double-blind, controlled trial: one, TCM treatments based on syndrome differentiation; the other, a placebo of TCM treatment.
- Detailed Description
Bronchiectasis is a common and frequently occurring respiratory disease, with more hospitalization rate and mortality, poor quality of life and heavy financial burden. The main clinical manifestations are persistent or recurrent cough, expectoration, sometimes accompanied by hemoptysis, which can cause respiratory dysfunction and chronic pulmonary heart disease. There are some randomized controlled trials of TCM for bronchiectasis, and have the effect in the treatment of bronchiectasis, reducing the number of acute aggravation and alleviating dyspnea. However, some TCM interventions lack comprehensive syndrome differentiation and the placebo control.
This is a multi-center, randomized, double-blind, controlled trial to compare the efficacy to evaluate the effectiveness of TCM on patients with clinically stable bronchiectasis. 216 subjects will be randomly assigned to one therapies (TCM treatments based on syndrome differentiation) and the other therapy (placebo of TCM treatment) for 24 weeks. After the treatment period, the subjects will be followed up for 24 weeks. The primary outcomes include the frequency of bronchiectasis exacerbation, and the secondary outcomes include quality of life (SGRQ, LCQ, QOL-B), pulmonary function, safety observation index.

Group Intervention Description TCM Bufei Huatan granule Patients in this group will receive two types of TCM treatment, which are Bufei Huatan granule, Yifei Qinghua granule. The herbal extract twice daily for 24 weeks for lower dosage. The two granules are corresponding to the two traditional Chinese syndromes in sequence, which are syndrome of qi deficiency of lung and phlegm-turbidity obstructing the lung, Qi and Yin deficiency of the lung and the phlegm-heat obstructing the lung. placebo TCM Placebo Bufei Huatan granule Patients in this group will be given two placebo TCM treatment, which are which are placebo Bufei Huatan granule, placebo Yifei Qinghua granule, corresponding to the two traditional Chinese syndromes in sequence, which are syndrome of qi deficiency of lung and phlegm-turbidity obstructing the lung, Qi and Yin deficiency of the lung and the phlegm-heat obstructing the lung. placebo TCM Placebo Yifei Qinghua granule Patients in this group will be given two placebo TCM treatment, which are which are placebo Bufei Huatan granule, placebo Yifei Qinghua granule, corresponding to the two traditional Chinese syndromes in sequence, which are syndrome of qi deficiency of lung and phlegm-turbidity obstructing the lung, Qi and Yin deficiency of the lung and the phlegm-heat obstructing the lung. TCM Yifei Qinghua granule Patients in this group will receive two types of TCM treatment, which are Bufei Huatan granule, Yifei Qinghua granule. The herbal extract twice daily for 24 weeks for lower dosage. The two granules are corresponding to the two traditional Chinese syndromes in sequence, which are syndrome of qi deficiency of lung and phlegm-turbidity obstructing the lung, Qi and Yin deficiency of the lung and the phlegm-heat obstructing the lung.
- Primary Outcome Measures
Name Time Method The frequency of bronchiectasis exacerbation Changes in the frequency of exacerbation at the week 12 and week 24 of the treatment phase, and at the week 24 of the follow-up phase compared with baseline. The bronchiectasis exacerbations often result in reduced quality of life, increased rate of lung function decline, increased hospitalization. It is important to assess the changes of bronchiectasis exacerbations over time.
- Secondary Outcome Measures
Name Time Method The time to the first bronchiectasis exacerbation Week 24 of the treatment phase. Changes in Forced expiratory volume in one second Changes in FEV1 at the week 24 of the treatment phase and the week 24 of the follow-up phase compared with baseline. Forced expiratory volume in one second (FEV1)is the amount of air that can be exhaled in one second. A positive change from baseline in FEV1 indicates improvement in lung function.
