Brief Summary:
This pilot study will assess the efficacy of sacral never stimulation (SNS) for the treatment of adult patients with active, mild-to-moderate rheumatoid arthritis or those with refractory disease. The study will enroll 60 subjects in a single center. All eligible subjects will be randomly divided into two groups at a ratio of 1:1. Half of the subjects will receive SNS (treatment) and the other half will receive sham stimulation (control). Subjects will be followed up for 2-4 weeks, according to their response to the treatment. Disease activity score, patient report outcomes and serum inflammatory cytokines will be observed before and after treatment.
Detailed Description:
Studies have shown that vagus nerve stimulation (VNS) may exert an anti-inflammatory effect through mechanisms like cholinergic anti-inflammatory pathway (CAP). This anti-inflammatory function of VNS has been verified in collagen induced arthritis (CIA) rats, RA patients, and animal models of inflammatory bowel disease (IBD). In recent years, it was reported that sacral nerve stimulation (SNS) is a safer way to exert a similar anti-inflammatory effect as VNS. Therefore, this study aims to explore the therapeutic effect of SNS on RA patients.
This is a randomized controlled clinical trial which will enroll 60 eligible RA patients. These subjects will be divided into two groups at a ratio of 1:1, the treatment group (Group 1) who will receive SNS and the control group (Group 2) who will receive sham stimulation. The patients will lie in prone position. In Group 1, a senior acupuncture doctor will pierce filiform needles through the sacral foramen into the S3 and S4 sacral nerves. These sites correspond to the Zhongliao and Xialiao acupoints in Traditional Chinese Medicine. In Group 2, shallow acupuncture stimulation will be performed at sites 8-10cm away from the acupoints in Group 1. In both groups, electrodes will be clamped on the filiform needles and an electrical current of 0.5 mA will be delivered. The stimulation will last for 60 minutes every time, once a day for 2 weeks. If the subjects respond to the treatment well, SNS treatment will be continued for 2 weeks. The following parameters will be measured before and 2-4 weeks after treatment:
1. Disease activity-related indexes of RA: swelling joint number (SJC), tender joint number (TJC), erythrocyte sedimentation rate (ESR), C-reactive protein (CRP);
2. Serum levels of inflammatory cytokines, including IL-6, IL-17, TNF-α, etc;
3. Patient report outcomes: Visual Analogue Scale (VAS) pain score, Health Assessment Questionnaire Disability Index (HAQ-DI) ;
4. Indexes of autonomic nervous function: serum level of norepinephrine (NE), heart rate variability (HRV).
