Study Details

Study Description

Brief Summary

This study will enroll 60 patients with mild to moderate active ulcerative colitis as subjects. They will be randomly divided into two groups: the TCM group received QHQYP rectal instillation, while the control group received mesalazine enema. The treatment period for both groups was 8 weeks. The modified Mayo Activity Index will be used as the main evaluation index. Secondary evaluation indices will include the Underwater Endoscopic Severity Index (UCEIS) score, endoscopic Baron score, mucosal histological score (Geboes index), Chinese medicine syndrome efficacy evaluation, quality of life score, physicochemical indicators reflecting disease activity or remission, intestinal microbiota indicators, and changes in inflammation and immune-related indicators in colonoscopy biopsy tissues. Safety indicators were also monitored.

Arms and Interventions

Arm Intervention/Treatment
Experimental: The TCM group is treated with QHQYP by rectal instillation.

QHQYP is decocted in water, with a dose of 100ml each time, and rectal instillation before going to bed, once a night, for 8 weeks.

Drug: Treatment group: Rectal instillation of QHQYP
QHQYP is decocted in water, with a dose of 100ml each time, and rectal drip before going to bed, once a night, for 8 weeks.
Other Names:
  • QHQYP is prepared by unified decocting from the Pharmacy Department of Beijing Hospital of Traditional Chinese Medicine, Capital Medical University.
  • Active Comparator: The control group is treated with mesalazine enema.

    Mesalazine enema, 4g/tube, 1 tube each time, enema before bed, once a night, for 8 weeks.

    Drug: Control group: Mesalazine enema treatment
    Mesalazine enema, 4g/tube, 1 tube each time, enema before bed, once a night, a total of 8 weeks of continuous treatment.
    Other Names:
  • Mesalazine enema is produced by Vifor AG Zweigniederlassung Medichemie Ettingen, National medicine approval H20150127.
  • Outcome Measures

    Primary Outcome Measures

    1. Change from Modified Mayo Activity Index at 8 weeks of treatment [Evaluation will be made at baseline and 8 weeks of treatment.]

      To understand the remission status of ulcerative colitis from the stool frequency, rectal bleeding, colonic mucosa condition and physician's overall evaluation. Each of the above aspects includes four levels (from 0 to 3, with higher scores indicating more severe disease).

    Secondary Outcome Measures

    1. Change from Ulcerative Colitis Endoscopic Index of Severity(UCEIS) at 8 weeks of treatment [Evaluation will be made at baseline and 8 weeks of treatment.]

      It focuses on three aspects: vascular pattern, bleeding and erosions&ulcers. The total score of the three scores can range from 0-8 (normal: 0, mild activity: 1-3, moderate activity: 4-6, and severe activity: 7-8.

    2. Change from Endoscopic Baron score at 8 weeks of treatment [Evaluation will be made at baseline and 8 weeks of treatment.]

      To understand the degree of activity of endoscopic ulcerative colitis.It includes four levels (from 0 to 3, with higher scores indicating more severe disease).

    3. Change from Geboes Score at 8 weeks of treatment [Evaluation will be made at baseline and 8 weeks of treatment.]

      To understand the status of mucosal tissue score. It ranges from Grade 0 (Architectural changes) , Grade 1 (chronic inflammatory cell infiltration), Grade 2 (neutrophils and eosinophils), Grade 3 (epithelial neutrophils) , Grade 4 (crypt destruction) to Grade 5 (erosion and ulcer). The higher the Geboes score, the more serious the disease activity. A grade lower than 2A.0 can be regarded as histological remission.

    4. Change from Evaluation of curative effect of traditional Chinese medicine syndrome at 8 weeks of treatment [Evaluation will be made at baseline and 2,4,8 weeks of treatment.]

      Traditional Chinese medicine (TCM) syndrome score of ulcerative colitis will be carried out to understand whether the symptoms of patients improved after treatment. It consists of 9 questions, and the total scores are ranging from 0 to 43 with higher scores indicating more severe disease.

    5. Change from Quality of life score at 8 weeks of treatment [Evaluation will be made at baseline and 8 weeks of treatment.]

      To understand the quality of life score of patients. It consists of 32 questions divided into four dimensions: bowel symptoms (10 items), systemic symptoms (5 items), emotional function (12 items) and social function (5 items). Every question has graded responses from 1 (worst situation) to 7 (best situation), and thus the total score is ranging from 32 to 224 with higher scores representing better quality of life.

    6. Change from Intestinal flora at 8 weeks of treatment [Examination will be performed at baseline and 8 weeks of treatment.]

      Fresh feces are collected at baseline and 8 weeks of treatment, and the distribution of intestinal flora is detected by 16s rRNA sequencing technology.

    Other Outcome Measures

    1. Change from Inflammation and immune-related indicators in colonoscopy biopsy tissues at 8 weeks of treatment [Examination will be performed at baseline and 8 weeks of treatment.]

      Colonoscopy biopsy tissues are collected at baseline and 8 weeks of treatment, and the Inflammation and immune-related indicators is detected by immumohistochemical staining.
