Ulcerative Colitis
Conditions
Brief summary
The aim of this study was to evaluate the efficacy and safety of transcutaneous electrical acustimulation in patients with mild to moderate ulcerative colitis.
Interventions
A transcutaneous electrical stimulator (TEA) device applies a mild electric stimulation through the skin, similar to acupuncture at the treatment site. The precise stimulating sites are not described upon registration to reduce unblinding risk.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Clinical response | 8 weeks | decrease of ≥3 points and ≥30% from baseline mayo score and decrease of ≥1 point in rectal bleeding subscore or absolute rectal bleeding subscore ≤ 1 |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Endoscopic remission | 8 weeks | defined as Mayo endoscopic score ≤ 1 |
| Clinical remission | 8 weeks | overall score ≤2 \[and no individual subscore \>1\] |
| Symptomatic remission | 2, 4, 6, and 8 weeks | Stool frequence subscore = 0 (or = 1 with a ≥ 1-point decrease from baseline) and rectal bleeding subscore = 0 |
| Fecal calprotectin | 4 and 8 weeks | fecal sample |
| erythrocyte sedimentation rate | 4 and 8 weeks | blood sample |
| C reactive protein | 4 and 8 weeks | blood sample |
| pancreatic polypeptide | 4 and 8 weeks | blood sample |
| Change from baseline in the Mayo score | 8 weeks | Mayo score at 8 week minus the Mayo score at baseline. The range of Mayo score is 0-12, and higher scores mean worse outcome. |
| acetyl choline | 4 and 8 weeks | blood sample |
| alpha7 nicotinic acetylcholine receptor | 8 weeks | Intestinal mucosal tissue sample |
| Inflammatory Bowel Disease Questionnaire Score | 4 and 8 weeks | The range of Inflammatory Bowel Disease Questionnaire Score is 32-224, and higher scores mean worse outcome |
| Hospital Anxiety and Depression scale score | 4 and 8 weeks | anxious depression. The range of Hospital Anxiety and Depression scale score is 0-21, and higher scores mean worse outcome. |
| Pittsburgh sleep quality index | 4 and 8 weeks | The range of Pittsburgh sleep quality index is 0-21, and higher scores mean worse outcome. |
| autonomic profile characteristics | 4 and 8 weeks | heart rate variability indicating sympathetic and parasympathetic activity |
| norepinephrine | 4 and 8 weeks | blood sample |
