Detailed Description
This randomized, double-blinded, sham acupuncture controlled trial is aimed to assess the effectiveness and safety of acupuncture in the treatment of Primary Sjögren Syndrome.The eligible participants will be randomly allocated to receive acupuncture or sham acupuncture for 8 weeks.
Assuming a two-sided alpha of 0.05, power of 85%, and a 20% drop-out, a sample sized of 30 would be needed for each group. The statistical analysis will be based on the intention-to-treat principle. Continuous variables will be compared by Student t test or Mann-Whitney U test; categorical variables will be analyzed by chi-square test, Fisher's exact test or Kruskal-Wallis H test as appropriate. For comparison between two time points, paired t-test or Wilcoxon signed rank test will be used as appropriate. A statistically significant difference was set at P<0.05.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Acupuncture group Participants will receive acupuncture for 8 weeks. In particular, acupuncture will be performed three times a week in earlier 4 weeks and twice a week in later 4 weeks. |
Device: acupuncture group
Acupoints include 11 on the head, two on the upper extremities, and two on the lower extremities. Before performing acupuncture, a small pad will be pasted on each acupoint. All the needles will insert the acupoints through these pads. Then, they will be twirled, lifted and thrust three times to elicit the Deqi sensation. Each session will last 30 minutes.
|
| Sham Comparator: Sham Acupuncture group Participants will receive sham acupuncture for 8 weeks. The procedure is the same as the acupuncture arm. |
Device: Sham Acupuncture group
The same acupoints with acupuncture group are selected.A placebo needle with a blunt tip will be used to perform sham acupuncture. They will only insert the pad and no skin penetration. The same procedure with acupuncture group will be performed.

Outcome Measures
Primary Outcome Measures
- The proportion of participants who has a 30% or greater reduction in 2 of 3 items,including the numeric analog scale (NAS) of dryness, fatigue, and pain. [24 weeks]
Subjects will be asked to provide every NAS score based on the average situation over the past 24 hours 13 rather than a point of time. And we will collect NAS scores three times a week in week0-8 (24 times in total) as removal of a variety of factors causing bias, including mental relaxation in weekend, weather changing, or unexpected events life in, etc., each of which may influence the feelings of dryness, fatigue, and pain.
Secondary Outcome Measures
- Change in NAS of each item including dryness, fatigue, and pain. [24 weeks]
Subjects will be asked to provide every NAS score based on the average situation over the past 24 hours 13 rather than a point of time. And we will collect NAS scores three times a week in week0-8 (24 times in total) as removal of a variety of factors causing bias, including mental relaxation in weekend, weather changing, or unexpected events life in, etc., each of which may influence the feelings of dryness, fatigue, and pain.

it will be measured at week0/8/16/24
