About

Major depressive disorder (MDD) is highly prevalent, affecting nearly 4% of the global population. Pharmacotherapy is the frontline treatment recommended by the guideline, but it also has some limitations such as delayed onset, inadequate response, and drug resistance. Intradermal acupuncture (IA) is a method of using short indwelling needles retained under the skin to produce continuous stimulation for long-term efficacy. It has been reported that IA combination medication appears to be more valuable than medication alone in the treatment of MDD, however, there is a lack of high-quality clinical evidence.While several studies have proposed that manual or electroacupuncture can improve MDD symptoms by modulating brain networks, the cerebral mechanism of IA as superficial acupuncture for MDD has not been reported. Hence, investigators designed a multicentre randomized controlled trial to assess the clinical efficacy and safety of IA for MDD and preliminarily explore the potential therapeutic mechanisms for IA by functional magnetic resonance imaging (fMRI) .

Full description

A total of 120 patients with MDD who meet the inclusion criteria will be included in the study. Participants will be randomly assigned 1:1:1 to the waiting list group (patients in this group will be treated with selective 5-hydroxytryptamine reuptake inhibitors (SSRIs) only), sham intradermal acupuncture combined with SSRIs (SIA) group and active intradermal acupuncture combined with SSRIs (AIA) group. The study will assess the efficacy and safety of intradermal acupuncture for MDD. In addition, investigator will explore the possible cerebral mechanisms by which IA exerts its antidepressant effects.

Trial design

Primary purpose: Treatment

Allocation: Randomized

Interventional model: Parallel Assignment

Masking: Double Blind

---

120 participants in 3 patient groups

Waiting list group

Other group

Description:

This group will include 40 patients with MDD who will be treated with oral SSRIs only, the dosage of which will be determined by the psychiatrist. At the end of this trial, patients could choose 6 weeks' intradermal acupuncture treatments free of charge.

Treatment:

Drug: SSRI

SIA group

Sham Comparator group

Description:

This group will include 40 patients with MDD who will be treated with sham intradermal acupuncture (SIA) combined with SSRIs. Acupoints related to MDD will be stimulated by acupuncturists and the dosage of oral SSRIs will be determined by the psychiatrist.

Treatment:

Drug: SSRI

Device: SIA

AIA group

Experimental group

Description:

This group will include 40 patients with MDD who will be treated with active intradermal acupuncture (AIA) combined with SSRIs. Acupoints related to MDD will be stimulated by acupuncturists and the dosage of oral SSRIs will be determined by the psychiatrist.

Treatment:

Drug: SSRI
