Brief summary: Ulcerative colitis (UC) is one of the two primary forms of inflammatory bowel disease. This condition is characterized by continuous mucosal inflammation that begins in the rectum and extends proximally throughout the colon. Common intestinal symptoms also include rectal bleeding, increased stool frequency, tenesmus, nocturnal bowel movements, and crampy abdominal pain. Acupuncture has been suggested as a potential intervention to alleviate clinical symptoms of UC. This single-center, parallel-group, two-arm, randomized, sham-controlled trial aims to evaluate the effects and safety of acupuncture for UC.

Detailed description: Ulcerative colitis (UC) is a chronic inflammatory bowel disease characterized by episodes of symptoms including rectal bleeding, increase stool frequency, and abdominal pain, impacting quality of life significantly. Conventional treatments often come with potential side effects and may not be sufficient. Acupuncture is increasingly recognized for its promising benefits in UC. This study aims to assess the efficacy and safety of acupuncture for symptom relief in mild to moderate UC.This single-center, parallel-arm, randomized, sham-controlled trial will involve 64 patients with UC, randomly assigned in a 1:1 ratio to either the acupuncture or sham acupuncture group. Participants will receive 20 sessions of acupuncture or sham acupuncture over eight weeks. Blinding will be applied to participants, outcome assessors, and statisticians. The primary outcome measure is the change in Patient-Reported Outcome 2 (PRO2) from baseline at week 8. Secondary outcomes include changes from baseline in the following scales: PRO2 at other time points, weekly average Numeric Rating Scale (U-NRS) for bowel urgency, weekly average NRS for abdominal pain (both associated and not associated with bowel movement), the 32-item Inflammatory Bowel Disease Questionnaire (IBDQ-32), Work Productivity and Activity Impairment Questionnaire-Inflammatory Bowel Disease (WPAI-IBD), Pittsburgh Sleep Quality Index (PSQI), and Hospital Anxiety and Depression Scale (HADS). Patient Global Impression of Change (PGIC) will also be assessed as secondary outcomes. Adverse events and additional treatments will be monitored throughout the study. The modified intention-to-treat (mITT) population will include participants who complete baseline assessments and receive at least one treatment session.

Eligibility criteria: Inclusion Criteria:

Eligible participants are those aged 18 to 70 years who meet the diagnostic criteria for mild to moderate UC, have a PRO2 score of ≥ 2 points, and provide written informed consent. Patients currently receiving oral and/or topical 5-aminosalicylic acid (such as mesalamine) may continue their treatment during the study period.

Exclusion Criteria:

Participants will be excluded if they meet any of the following criteria:

1. Diagnosis of Crohn's disease, intestinal tuberculosis, chronic intestinal infections, or intestinal malignancies.
2. Current treatment with corticosteroids, thiopurines, biologics, or oral small molecules.
3. Severe skin conditions or infections.
4. Presence of severe underlying medical conditions, including but not limited to cardiovascular diseases, hepatobiliary diseases, kidney diseases, hematologic disorders, autoimmune diseases, communicable diseases, severe malnutrition, or malignancies.
5. Mental illness, cognitive dysfunction, or language disorders.
6. Receipt of acupuncture therapy for UC within the past month.
7. Substance abuse issues.
8. Pregnancy, plans to become pregnant within the next year, lactation, or being within 12 months postpartum.
