Electroacupuncture for juvenile idiopathic arthritis: clinical efficacy and its role in modulating pyroptosis and autophagy pathways.

Background: Juvenile idiopathic arthritis (JIA) is a common chronic inflammatory disorder in children, leading to significant physical and psychosocial challenges. Current treatments often fall short, prompting interest in complementary therapies. This study aims to evaluate the effectiveness of electroacupuncture (EA) on clinical outcomes in children with JIA, focusing on its impact on the pyroptosis pathway and autophagy function.

Methods: A randomized controlled clinical trial was conducted from 7 November 2023 to 12 January 2025. A total of 106 participants were recruited and randomly assigned to receive EA or sham acupuncture (SA) for 8 weeks. Clinical assessments, including functional ability, pain scores, and quality of life, were measured at baseline, week 4, week 8, month 3, and month 6. Serum levels of pyroptosis-related proteins and autophagy markers were analyzed to elucidate the underlying mechanisms.

Results: The EA group showed significant improvements in functional ability and pain scores compared to the SA group at both week 4 and week 8. Notable reductions in serum levels of pyroptosis markers (caspase-1, GSDMD, NLRP3) and pro-inflammatory cytokines (IL-1β, IL-18) were observed in the EA group. Additionally, autophagy markers (LC3, Becline1) significantly decreased after EA treatment, suggesting enhanced autophagic activity.

Conclusion: This study demonstrates that electroacupuncture is a safe and effective adjunctive treatment for improving function and reducing pain in children with JIA. The observed biological changes indicate potential anti-inflammatory effects, supporting EA's role in comprehensive JIA management. Future research should explore long-term outcomes and mechanisms for these findings further. Key Points • The study demonstrates that electroacupuncture (EA) significantly improves functional ability and pain scores in children with juvenile idiopathic arthritis (JIA) compared to sham acupuncture. • EA treatment led to notable reductions in serum levels of pyroptosis-related proteins and pro-inflammatory cytokines, indicating its potential role in modulating inflammatory pathways. • The research observed significant changes in autophagy markers post-EA treatment, suggesting that EA may enhance autophagic function in children with JIA. • EA is presented as a safe adjunctive therapy for JIA management, with implications for further research into its long-term effects and underlying mechanisms.
