简要总结
The purpose of this study is to evaluate the efficacy of Suan-Zao-Ren Tang in improving sleep quality, anxiety, depression, and heroin craving among methadone-maintained persons with sleep complaints.
详细描述
Background:
Heroin dependence is one of the major health issues worldwide. Methadone Maintenance Therapy (MMT) is an effective treatment for opioid dependence, but more than three quarters of persons receiving MMT report sleep complaints. Traditional Chinese Medicine (TCM) is one of the most common complementary therapies offered to insomnia patients in Taiwan. Investigators designed a randomized, double-blind, placebo-controlled clinical trial to evaluate the efficacy of TCM in methadone-maintained persons with sleep disturbance.
Methods/design:
In this study, inclusion criteria are persons receiving MMT for at least one month, more than 20 years old, complain insomnia with a Pittsburgh Sleep Quality Index (PSQI) of six or higher. Exclusion criteria include being pregnancy, had serious physical or mental illness, current use (last 30 days) of TCM, had received any antidepressant or neuroleptic medication and inability to read and fill out the forms for the study. The patients were separated into an intervention group (Suan-Zao-Ren Tang, SZRT) and a placebo group for four weeks using a randomized, double-blind procedure. Outcome measures will be assessed at baseline, 4 weeks and 8 weeks after receiving medication. PSQI was used to assess sleep quality over the past 30 days, anxiety and depression levels measured by the Beck Anxiety Inventory (BAI) and Beck Depression Inventory II (BDI-II) were also conducted, heroin craving degree was evaluated by the change of the visual analog scale (VAS). Serum proteins will be detected using a proteomics method based on two-dimensional gel electrophoresis, and the specificity of proteins will confirmed by western blotting. T-test and chi-square tests are used for statistical analysis.

结局指标
主要结局
sleep quality
时间窗: The patients will complete the questionnaire at baseline (first visit), four weeks later (second visit), and eight weeks later (third visit).
The primary outcome measure under study is the sleep quality. Sleep quality will be assessed using the Taiwanese version of the PSQI, which has demonstrated reliability and validity. It evaluates sleep disturbances in 7subscales: subjective sleep quality, sleep latency, sleep duration, habitual sleep efficiency, sleep disturbances, use of sleeping medication and daytime dysfunction. Each subscale is rated on a 4-point scale (0 to 3, with 3 indicating a more profound effect), which is summed together to yield a global score (0to21).
次要结局
- severity of heroin craving(The patients will complete the questionnaire at baseline (first visit), four weeks later (second visit), and eight weeks later (third visit).)
- Beck Anxiety inventory (BAI)(The patients will complete the questionnaire at baseline (first visit), four weeks later (second visit), and eight weeks later (third visit).)
- Beck Depression Inventory (BDI-II, second edition)(The patients will complete the questionnaire at baseline (first visit), four weeks later (second visit), and eight weeks later (third visit).)
