Brief Summary

This project plans to develop a new diet therapy suitable for China -- CD-C-food, which is more in line with the common diet of Chinese patients' eating habits and economic conditions, and its expected therapeutic effect and influence on intestinal microorganism are similar to that of EEN. In order to explore the influence of intestinal microorganisms and their metabolites on the clinical remission effect and inflammatory response of patients with CD-C-Food, and to reveal the possible internal mechanism， a randomized control of adult subjects with a healthy CD-Chinese-food diet, treatment group of CD patients and animal model will be conducted by using intestinal microbiome, bacterial metabolite analysis, inflammatory factors detection and other technical means.

Detailed Description

Exclusive Enteral Nutrition (EEN) is the only established dietary treatment for children with CD.Changes in diet affect the amount of short-chain fatty acids and branched-chain fatty acids produced by changing the composition of intestinal flora, leading to changes in intestinal state.Through the long-term clinical observation of our team, most patients with CD can achieve stable remission by removing the processed food and screening the corresponding food by combining the characteristics of Chinese diet with the food intolerance detection method. So, what kind of diet is suitable for the treatment of CD patients in China? The CD-Treat program, replacing the Western diet with Chinese diet, so as to design an individualized program CD-Chinese-food (CD-C-food) that is consistent with the eating habits of Chinese patients with CD. By comparing the effects of this individualized diet with EEN on inducing and maintaining remission in CD patients.

Study Groups

CD-C-Food group

During the first 3 months，participants received EEN；In the second 3months , CD-C-Food group received received CD-C-food .

CD-C-Food

Intervention Type: DIETARY_SUPPLEMENT

CD patients combined with the characteristics of Chinese diet, remove the refined food, and combined with food intolerance detection method to check the corresponding food

EEN group

During the period, participants received EEN for 6 months.

Exclusion Criteria

2. CD patients who currently need or expect surgical intervention during the study period.

3. CD patients with symptoms or signs of perforation such as abdominal abscess, intestinal fistula, etc.

4. Patients with complete intestinal obstruction or fibrous stenosis with pre-stenosis dilation that require surgery to relieve the obstruction.

5. CD patients with colorectal tumors. Those who have EN contraindications (active gastrointestinal bleeding, severe esophageal and gastric varices, intestinal obstruction, abdominal cavity syndrome, etc.).

6. Pregnancy and breastfeeding patients.

7. Severe hemodynamics, unstable vital signs, or the presence of rapid progression or end-stage disease, are expected to die during the course of the study.

8. Patients diagnosed with short bowel syndrome or with ileostomy or colostomy.

9. Patients with severe liver and kidney dysfunction, active infection, or other reasons (such as previous infliximab anaphylactic shock) cannot tolerate the treatment drugs used in this study.

10. The patient is allergic to known ingredients of enteral nutrition or has no previous EEN for 12 weeks.
