Assessment of Adherence to Gluten Free Diet in Children and Adolescents by Detection of Gluten in Faecal Samples.

September 30, 2021 updated by: raanan shamir, Rabin Medical Center

Assessment of Adherence to Gluten Free Diet in Children and Adolescents by Detection of Gluten Immunogenic Peptides in Faecal Samples and Nutritional Assessment. Retrospective Study

To assess the adherence to gluten free diet by measuring faecal and urinary gluten immunogenic peptides (GIP). This will provide an objective measure for adherence.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The adherence to the GFD can be assessed through a dietary interview performed by a registered dietitian or patient self-reports, mucosal healing, assessed by a small bowel biopsy or CD serological screening tests showing decreasing levels of antibodies. However, none of these methods offer an accurate measure of dietary compliance. A novel method to monitor the adherence to the GFD by detection of immune-dominant gluten peptides in human faeces or urine using the anti-α -gliadin G12 antibody was described recently in the literature. Gluten peptides, in particular peptides equivalent to the immunogenic - α -gliadin-33-mer peptide, are resistant to gastrointestinal digestion and that ensures a significant amount of the ingested gluten is excreted in faeces. Consequently, recovery of detectable amounts of the immunogenic fraction in faeces or urine indicates that gluten has passed through the digestive tract, and in the case of urine was absorbed, and, therefore, that gluten has been consumed .

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

Study Population

  1. Children and adolescents aged 2-17 years, reported to be on gluten free diet for at least a year, diagnosed with celiac disease
  2. Children and adolescents aged 2-17 years that are reported to be noncompliant with gluten free diet, diagnosed with celiac disease for at least 1 year.
  3. Healthy controls aged 2-17 years old matched for age and sex.

Description

Inclusion Criteria:

  • Age 2-17 years.
  • Either diagnosis of celiac disease or, in controls, no systemic disease or inflammation
  • For all groups parents will provide informed consent.

Exclusion Criteria:

° Children with suspected or known inflammatory bowel disease or other gastrointestinal or systemic diseases.

Diagnostic test: detecting Gluten peptides in faecal and urine samples

At each visit patient will:

  • Bring 4-day food diary (attached)
  • Fill symptoms and complaints questionnaire (attached)
  • Provide 24 h diet recall in case a food diary absents
  • Fill Biagi score questionnaire (attached)
  • Perform blood test of TTG
  • Provide stool and urine samples

Healthy controls aged 2-17 years old matched for age and sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Correlation between fecal gluten peptides and nutritional assessment for gluten free diet, and correlation with celiac serology.
Time Frame: one year
Our goal is to examine which method will be the most accurate, nutritional assessment or laboratory tests for the adherence to GFD
one year
