Specific Dietary Pattern for Crohn's Disease Patients Following Surgery

Second Affiliated Hospital, School of Medicine, Zhejiang University35 enrolled

Overview

Over the past 10 years, there are a large number of dietary treatments related to the CD, such as specific carbohydrate diet, low Fermentable Oligo-, Di-, Mono-saccharides And Polyols (FODMAP) diet, and allergen-free foods. But there is no consistent conclusion or convincing evidence about the effectiveness. Through the long-term clinical experience observation, we find most of the CD patients can get stable remission by removing refined food and intolerance food.This project aims at developing a new dietary therapy suitable for Chinese patients.

The dietary therapy is based on the nutrient composition of exclusive enteral nutrition and is more in line with Chinese patients' dietary habits and economic conditions.

Outcomes

Primary Outcomes

Quality of Life(IBDQ)

IBDQ: Inflammatory Bowel Disease Questionnaire.The IBDQ evaluates the quality of life of patients from four aspects: intestinal symptoms, systemic symptoms, emotional function and social function. There are 32 questions in the questionnaire, with a total score of 32 to 224 points. The higher the score, the higher the quality of life of the patient.

Time frame: The two groups of patients were scored at first week and sixth week after surgery.

Secondary Outcomes

nutritional status of the patient

Body composition analysis, calf circumference in centimeter , albumin in g/L, hemoglobin in g/L, were measured to evaluate the nutritional status

Time frame: The two groups were evaluated at first week and sixth week after surgery.

Disease-related evaluation indicators

We assessed the effect of the intervention on disease by measuring the following indicators: Harvey-Bradshaw Index(HBI), Crohn's Disease Activity Index (CDAI), C Reactive Protein (CRP)in mg/L, Erythrocyte Sedimentation Rate (ESR) in mm/h, platelets in 10\^9/L, triglycerides in m mol/L, cholesterol in m mol/L , uric acid in u mol/L.
