A Meta-analysis of Different Acupuncture Modalities Combined With Antidepressants to Reduce Major Depressive Disorder.

OBJECTIVES

Acupuncture is an effective therapy for depression. Nevertheless, the results of clinical studies on major depressive disorder (MDD) remain controversial.

METHODS

By November 2023, English-language published randomized clinical trials involving acupuncture for treating MDD were searched. The analysis comprised 9 studies with 809 subjects who met the eligibility criteria. The quality of the included studies was evaluated using the Quality in Prognostic Studies (QUIPS) tool.

RESULTS

Acupuncture moderately alleviated the severity of MDD, independent of the method used (standardized mean difference [SMD] = -0.55; confidence interval [CI] 95%: -1.19, 0.09; P = 0.08). The severity of MDD was moderated by MA, regardless of antidepressant use (SMD = -0.49; CI95%: -1.13, 0.14, P = 0.09). Subgroup analysis revealed a nonsignificant reduction in MDD severity when using manual acupuncture alone (SMD -0.52; CI95%: -1.47, 0.44, P = 0.18). MDD severity was reduced by the use of manual acupuncture and antidepressants (SMD = -0.47; CI95%: -0.88, -0.06). Laser acupuncture and electroacupuncture (with or without antidepressants) did not significantly affect the severity of MDD.

CONCLUSIONS

Manual acupuncture with or without antidepressants may alleviate the severity of MDD, but its clinical benefit for treating MDD is inconclusive.
