Efficacy and safety of acupuncture therapy combined with conventional pharmacotherapy in the treatment of systemic lupus erythematosus: A systematic review and meta-analysis.

Abstract

Currently, the mainstream treatments for systemic lupus erythematosus (SLE) are based on glucocorticoids and immunosuppressants, which are known to have considerable adverse effects. This meta-analysis is aimed at confirming the efficacy and safety of acupuncture therapy in combination with traditional medications in the treatment of SLE. Multiple databases were searched for randomized controlled trials using acupuncture therapy in combination with conventional pharmacotherapy for the treatment of SLE, from the establishment of the database to March 2023. Study selection, data collection, as well as quality assessment were conducted by 2 reviewers independently. RevMan 5.4 and Stata 17 software were used for Meta-analysis. Seven eligible studies involving 514 patients with SLE were included. Meta-analysis demonstrated that in SLE patients, extra treatment with acupuncture was superior to drug therapy alone in improving the overall response rate (RR = 1.20, 95% confidence intervals [1.11, 1.29], P < .00001, heterogeneity P = .69, I2 = 0%) and regulating immunological indicators (C3, C4, IgG, T lymphocyte subpopulation, IL-6, ds-DNA, ESR) while reducing TCM symptom scores, the SLE Disease Activity Index (SLEDAI) and the incidence of adverse events on treatment (P ≤ 0.05). Additionally, it was able to reduce BUN, Scr and 24 hours urine protein, suggesting that acupuncture treatment had a protective effect on the kidneys. Acupuncture therapy combined with conventional pharmacotherapy is an efficient and safe way in the treatment of SLE. However, the conclusions drawn from this meta-analysis have some limitations due to the small number and uneven quality of the included studies, leading to heterogeneity and bias. Thus more relevant high-quality randomized controlled trials are needed for further evaluation in the future.
