简要总结
A randomized controlled trial involving 140 subjects with (Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition) DSM-5 insomnia disorder after excluding those with other medical conditions, psychiatric disorders, and sleep disorders that may cause insomnia. The subjects will be randomly assigned to either acupuncture treatment or sham acupuncture (control group) in a 1:1 ratio. The acupuncture treatment group will receive acupuncture treatments using a semi-standardized protocol. In a similar way, the sham acupuncture control group will receive acupuncture using validated non-invasive sham acupuncture needles. Both subjective (the sleep questionnaire and sleep diary) and objective (actigraphy) outcome measures will be recorded at baseline and at 1- and 5-week post-treatment. Fasting blood samples will be taken on the morning of the assessments at these time points to measure the oxidative stress parameters, including the malondialdehyde (MDA) level, and the glutathione peroxidase (GPx), paraoxonase (PON), and arylesterase (ARE) activities. The primary outcome is sleep efficiency, measured using a 7-day sleep diary and the oxidative stress parameters at 1-week post-treatment.
详细描述
Background: Insomnia is a very common complaint worldwide. Acupuncture is an alternative treatment for improving sleep quality. However, its efficacy and mechanism of action as a treatment for insomnia requires further investigation. Acupuncture may attenuate oxidative stress which is thought to be an important pathophysiological factor in insomnia.
Aims: To evaluate the safety and efficacy of a semi-individualized acupuncture treatment in improving sleep, and to examine its effects on oxidative stress parameters in subjects with primary insomnia disorder.
Methods: This will be a randomized controlled trial involving 140 subjects with DSM-5 insomnia disorder after excluding those with other medical conditions, psychiatric disorders, and sleep disorders that may cause insomnia. The subjects will be randomly assigned to either acupuncture treatment or sham acupuncture (control group) in a 1:1 ratio. The acupuncture treatment group will receive acupuncture treatments using a semi-standardized protocol. In a similar way, the sham acupuncture control group will receive acupuncture using validated non-invasive sham acupuncture needles. Both subjective (the sleep questionnaire and sleep diary) and objective (actigraphy) outcome measures will be recorded at baseline and at 1- and 5-week post-treatment. Fasting blood samples will be taken on the morning of the assessments at these time points to measure the oxidative stress parameters, including the malondialdehyde (MDA) level, and the glutathione peroxidase (GPx), paraoxonase (PON), and arylesterase (ARE) activities. The primary outcome is sleep efficiency, measured using a 7-day sleep diary and the oxidative stress parameters at 1-week post-treatment.
Data analysis: Changes in the sleep and oxidative stress outcome measures will be compared between groups by using a mixed-effects model at each time point. Correlations between sleep parameters and oxidative stress parameters will be examined using a Pearson correlation. Mediation analysis will be performed to explore the possible mediating effect of oxidative stress factors on sleep.
Significance: The relationship between oxidative stress and insomnia severity has been under-researched. To the best of our knowledge, there has thus far been no study on the effect of acupuncture on oxidative stress in subjects with insomnia disorder. The present study will not only provide high-quality evidence of the efficacy of acupuncture as a treatment for insomnia, but also of the associated changes in oxidative stress parameters. It will guide future studies on the treatment mechanism and pathophysiology of insomnia.
