• Conditions: COPD Exacerbation Acute; Asthma Acute

• Registration Number: NCT06869525
• Lead Sponsor: Henan University of Traditional Chinese Medicine

Brief Summary

For patients in the acute phase of chronic airway diseases, on the basis of guideline-directed treatment, the experimental group was given acupuncture treatment, while the control group was given sham acupuncture treatment. The treatment lasted for one week, followed by a 13-week follow-up. For asthma and COPD, PEF and CAT were respectively used as the primary outcome measures to evaluate the clinical efficacy and safety of acupuncture. Based on the improvement of the primary outcome measures, the advantageous population was identified. The mechanism by which acupuncture reduces airway mucus hypersecretion was preliminarily explained.

Detailed Description

This study was a multicenter, randomized, double-blind, controlled trial. A total of 336 patients with acute exacerbation of chronic obstructive pulmonary disease (COPD) and 240 patients with acute attack of asthma were included. On the basis of guideline-directed treatment, the experimental group received acupuncture treatment, while the control group was given sham acupuncture treatment. For patients with AECOPD, the acupoints selected were Zhongfu, Dingchuan, Tiantu, Fenglong, and Feishu. For patients with acute attack of asthma, the acupoints selected were Dingchuan, Zhongfu, Tiantu, Feishu, and Kongzui. The acupoints were connected to electroacupuncture and treated for 30 minutes. The control group received sham acupuncture treatment. The acupoints were located 5 to 10 mm away from the actual acupoints, and the needles were inserted superficially through the skin. The acupoints were connected to electroacupuncture but without electricity. The treatment lasted for 30 minutes, once a day, for one week. Follow-up was conducted for 13 weeks. For COPD, the COPD Assessment Test (CAT) was the primary outcome measure, and the secondary outcome measures included the mMRC scale, assessment of airway mucus hypersecretion, CT assessment of airway mucus, basic vital signs, clinical symptom scores, use of control medications and antibiotics, acute exacerbation status, hospitalization time, tracheal intubation rate, and arterial blood gas. For asthma, the peak expiratory flow (PEF) was the primary outcome measure, and the secondary outcome measures included the Asthma Control Test (ACT), Asthma Control Questionnaire (ACQ), Asthma Quality of Life Questionnaire (AQLQ), assessment of airway mucus hypersecretion, CT assessment of airway mucus, basic vital signs, clinical symptom scores, use of control medications and antibiotics, acute attack status, hospitalization time, and fractional exhaled nitric oxide (FeNO). The clinical efficacy and safety of acupuncture were evaluated. The population with advantages was identified based on the improvement of the primary outcome measures. The mechanism of acupuncture in reducing airway mucus hypersecretion was preliminarily explained.

Primary Outcome Measures

Name	Time	Method
COPD part：CTA	Before treatment, at 4 and 7 days of treatment, and at 4 and 13 weeks of follow-up	Record the COPD Assessment Test (CAT) for each patient, and evaluate the impact of acupuncture on improving the clinical symptoms of patients with AECOPD.
Astham part: PEF	Before treatment, at 4 and 7 days of treatment, and at 4 and 13 weeks of follow-up	Record the peak expiratory flow rate(PEF) for each patient, and evaluate the impact of acupuncture on improving the peak expiratory flow (PEF) of asthma patients.

Secondary Outcome Measures

Name	Time	Method
Asthma part：Asthma Quality of Life Questionnaire(AQLQ)	Before treatment, at 4 and 7 days of treatment, and at 4 and 13 weeks of follow-up	The asthma quality of life scale (5-point scale-RRB- consists of 35 items, including activity limitation (1-12) , asthma symptoms (13-20) , psychological status (22-26) , response to stimuli (27-31) , concern for one's own health (32-35) . On a 5-point scale, 1 is the worst and 5 is the best.
Asthma part：The cough and expectoration assessment questionnaire (CASA-Q)	Before treatment, at 4 and 7 days of treatment, and at 4 and 13 weeks of follow-up	Each indicator of the patient is scored from 1 to 5 based on the severity. After reverse scoring, the lower the score, the more severe the airway mucus hypersecretion and the poorer the therapeutic effect.
Asthma part：Asthma Control Questionnaire(ACQ)	Before treatment, at 4 and 7 days of treatment, and at 4 and 13 weeks of follow-up	The content of ACQ involves the following aspects: asthma-related, symptoms, the use of first-aid drugs, the impact on daily life and lung function test results.The higher the score, the worse the state.
Astham part: the Asthma Control Test (ACT)	Before treatment, at 4 and 7 days of treatment, and at 4 and 13 weeks of follow-up	ACT includes five questions. Every question will be assessed using a 5-point scale with scores ranging from 5 to 25. The higher the score, the better the symptom control.25 is considered complete control level, 20 \~ 24 is considered good control level, and \<20 is considered non-control level.
Asthma part：Evaluation of Airway Mucus by CT Imaging	Before treatment, and day 7	Airway mucus CT assessment evaluates the distribution characteristics of airway mucus through the imaging features of thin-layer CT.
Asthma part：Evaluation of Airway Mucus Hypersecretion	Before treatment, at 4 and 7 days of treatment, and at 4 and 13 weeks of follow-up	The assessment includes: the difficulty of expectoration score, the sputum character score, and the sputum viscosity grading. They represent the nature of the sputum and the difficulty of coughing, ranging from 0 to 3 points. The higher the score, the more mucus secretion in the airway and the more severe the symptoms.
Asthma part：Clinical symptom score	Before treatment, at 4 and 7 days of treatment, and at 4 and 13 weeks of follow-up	Including wheezing, coughing, expectoration, chest tightness and wheezing sounds.A score of 0-3 will be given to every symptom or sign with a higher score indicating a worse conditoin.

Asthma part：Hospitalization time	At 4 weeks of follow-up	The time required from the point of enrollment to the attainment of the discharge criteria
Asthma part：Fractional exhaled nitric oxide (FeNO)	Before treatment, and day 7	FeNO is measured by a FeNO detector. It is used to determine the concentration of nitric oxide in exhaled breath of the human body. As a biomarker of airway inflammation, its normal range is less than 25ppb (adults) .
COPD part：clinical symptoms and signs questionnaire	Before treatment, at 4 and 7 days of treatment, and at 4 and 13 weeks of follow-up	Assessment will be performed by clinical symptoms and signs questionnaire. The clinical symptoms to be evaluated in this study include cough, phlegm, chest tightness, gasp,shortness of breath, feeble and cyanosis. A score of 0-3 will be given to every symptom or sign with a higher score indicating a worse conditoin.

COPD part：The cough and expectoration assessment questionnaire (CASA-Q)	Before treatment, at 4 and 7 days of treatment, and at 4 and 13 weeks of follow-up	Each indicator of the patient is scored from 1 to 5 based on the severity. After reverse scoring, the lower the score, the more severe the airway mucus hypersecretion and the poorer the therapeutic effect.
