Long-term Safety and Efficacy of Sacral Nerve Stimulation in Patients With Ulcerative Colitis

Although the incidence of inflammatory bowel disease is stable in North American and European countries, the incidence of inflammatory bowel disease is increasing in newly industrialized countries, especially in China. The treatment drugs for ulcerative colitis include 5-aminosalicylic acid (5-ASA), glucocorticoids, immunosuppressants, and biological agents. The aim of this clinical trial is to evaluate the long-term safety and efficacy of sacral nerve stimulation in patients with ulcerative colitis

Treatment and study plan

sacral nerve stimulation

Device

Device: G132 system, Beijing PINS Medical Co., China Neuromodulation was performed according to the usual protocol

Primary outcomes

  1. Change from baseline in the Mayo score

    Time frame: From baseline to 8 years

    The range of Mayo score is 0-12, and higher scores mean worse outcome

Secondary outcomes

  1. Clinical remission

    Time frame: From baseline to 8 years

    overall mayo score ≤2 [and no individual subscore >1]

  2. Clinical response

    Time frame: From baseline to 8 years

    defined as the reduction of baseline scores by ≥3 points

  3. Change from baseline in the Truelove and Witts Severity Index

    Time frame: From baseline to 8 years

    Truelove and Witts Severity Index

  4. Endoscopic remission

    Time frame: From baseline to 8 years

    defined as Mayo endoscopic score ≤ 1

  5. Fecal calprotectin levels

    Time frame: From baseline to 8 years

    fecal sample

  6. erythrocyte sedimentation rate levels

    Time frame: From baseline to 8 years

    blood sample

  7. C reactive protein levels

    Time frame: From baseline to 8 years

    blood sample

  8. Inflammatory Bowel Disease Questionnaire Score

    Time frame: From baseline to 8 years

    The range of Inflammatory Bowel Disease Questionnaire Score is 32-224, and higher scores mean worse outcome

  9. Hospital Anxiety and Depression scale score

    Time frame: From baseline to 8 years

    The range of Hospital Anxiety and Depression scale score is 0-21, and higher scores mean worse outcome

  10. Gut microbiota profile

    Time frame: From baseline to 8 years

    fecal sample

  11. The Pittsburgh Sleep Quality Index

    Time frame: From baseline to 8 years

    higher scores mean worse outcome
