About this trial

Food intolerance (FI) is an adverse reaction to food caused by non-immune mechanisms, mainly related to digestive enzyme deficiencies (e.g. lactase deficiency), metabolic abnormalities (e.g. impaired absorption of fructose) or toxicity of food components (e.g. histamine). Unlike immune-mediated food allergy, FI symptoms are usually delayed (hours to days after ingestion) and mild, but are difficult to diagnose and manage clinically due to the complexity and variety of mechanisms that affect approximately 20% of the world's population.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Food intolerance occurs through laboratory examination of at least two main foods

Underwent washed microbiota transplantation.

Disqualifiers

Expected survival time <3 months;

Women who are pregnant or breastfeeding;

Other patients deemed not suitable for enrollment by the investigator.

Trial population

Patients with food intolerance receiving WMT will be enrolled.

Treatments tested in this trial

  • washed microbiota transplantation

    Procedure/Surgery

    The prepared microbiota suspension was infused into the patients' gut.

Trial outcomes

Primary outcomes

1

change of weight and height

Weight and height will be combined to report BMI in kg/m\^2.

Time frame
baseline, 4 weeks, 12 weeks post transplantation
2

change of the Gastrointestinal Symptom Rating Scale(GSRS)

GSRS is a 13-item test to make a comprehensive assessment of common gastrointestinal symptom and each item receives a value from 0 to 3, with higher value indicating worse gastrointestinal condition.

Time frame
baseline, 4 weeks, 12 weeks post transplantation

Secondary outcomes

1

change of insulin-like growth factor I(IGF-I),intestinal barrier function and immunoglobulin

Blood test

Time frame
baseline, 12 weeks post transplantation
2

the difference of the gut microbiota composition before and after washed microbiota transplantation

The composition of the gut microbiota is evaluated by sequencing faecal metagenome. We evaluate the differences in the structure of the flora and its metabolism.

Time frame
baseline, 12 weeks post transplantation
3

the incidence of treatment-related adverse events (AE) assessed by CTCAE, Version 5.0

The severity of AE was graded as mild (grade 1), moderate (grade 2), severe/disabling (grade 3), life threatening (grade 4), and death (grade 5). All AE were divided in definitely, probably and possibly related to treatment. The treatment-related AE we focused on included microbiota-related AEs (e.g., infection, diarrhea, abdominal pain, etc.) and route of delivery related AEs (e.g., nausea, vomiting, etc.).

Time frame
12 weeks post transplantation
