About

Major depressive disorder (MDD) is a serious psychiatric illness with a high lifetime prevalence rate and causes major clinical, social and economic burden to patients and their family. Despite more than 40 antidepressants with various mechanisms are available on the market, half of patients fail to achieve remission with optimized medication treatment. Due to unsatisfactory efficacy, frequent intolerability and poor compliance of psychopharmacotherapies, novel and safe alternative therapies are critically in need to improve the treatment of depression.

Traditional Chinese medicine (TCM) theory describes a state of health maintained by a balance of energy in the body. If imbalanced, it can be corrected by acupuncture, the insertion of fine needles into different parts of the body. Although there are several clinical trials to demonstrate the antidepressant effects of acupuncture, its biological and physiological mechanisms are still unknown. In addition, clinical depression is frequently accompanied with somatic presentations, which are related to autonomic nervous dysfunction. It would be of interest to know if acupuncture could regulate autonomic nervous system (ANS) and improve the somatic symptoms in depression. The purpose of this study is to assess the effectiveness of acupuncture in the treatment of depression and to determine the influence of acupuncture on the molecular and ANS systems.

Full description

In this study,the investigators will test the antidepressant effect of acupuncture versus sham intervention on major depression, in an eight-week, double-blind, randomized-controlled trial in 40 MDD patients who still have significant depressive symptoms without changing at their treatment modality for the last 4 weeks. During the visits at weeks 0 (baseline), 1, 2, 4, 6, 8 (intervention), and 12 (4 weeks after intervention), subjects will be assessed depressive symptoms with the 21-item Hamilton Rating Scale for Depression (HAM-D). Before and after the intervention (Weeks 0 and 8),Computerized TCM constitution diagnosis will be measured and the blood samples will be collected for biomarker analyses, including neurotransmitter, inflammatory molecules and immunologic function. All parts of this research will start after being approved by the Institution Review Board in study sites.

The outcomes of this study could provide the evidence of applying acupuncture as an alternative effective treatment for depression and to improve the understanding of biological mechanisms for its antidepressant effects.

40 participants in 2 patient groups

acupucture

Experimental group

Description:

For real acupuncture, disposable acupuncture needles (0.22 x 30-mm sterile stainless needles) were inserted into acupoints for a depth of 10-30 mm in a direction oblique or parallel to the surface.

Treatment:

Other: Acupuncture

control

Sham Comparator group

Description:

For sham acupuncture procedure, Streitberger's noninvasive placebo acupuncture needles will be used. Its validity and credibility have been well demonstrated (Streitberger and Kleinhenz, 1998). The needles will be affixed with plastic O-rings and adhesive tapes. The needles with blunt tips will be quickly put onto the same acupoints used in real acupuncture without inserting into the skin.
