Brief Summary

The use of a home rapid test for the detection of both gluten immunogenic peptides (GIP) in urine and immunoglobulin A (IgA) anti tissue transglutaminase (anti-tTG) antibodies in blood may contribute to the early detection of volunteers who suffer celiac disease (CD), a highly under-diagnosed disorder. Patients with positive results could inform their doctors in order to accelerate the diagnosis, contribute to symptoms control and improve their quality of life. This observational, cross-sectional study with no interventions applied in subjects consists on a single group of volunteers between 2 and 18 years old. They will be given an informed consent which must be signed by them or their parents/legal guardians, a Celiac Symptoms Index (CSI) questionnaire and the sample collection material required on the testing day. Urine samples will be collected and analysed in situ or alternatively they will be stored and analyzed after at the laboratory. Blood samples will be collected and analyzed in situ the testing day. The main outcome is to determine the prevalence of CD through mass screening within the pediatric and adolescent population in order to provide an early diagnosis and avoid long-term consequences which are suffered by untreated patients. As an international innovation, misdiagnosis (false negatives) because of an insufficient gluten intake are expected to be detected, thus the use of GIP detection in urine will confirm gluten ingestion at the diagnosis. Volunteers with a confirmed diagnosis of CD could be monitored by their doctors to corroborate whether a gluten-free diet improves their quality of life.

Outcome Measures

Primary Outcomes (2)

  • Presence of Gluten Immunogenic Peptide (GIP) in urine

    The immunochromatographic test iVYCHECK GIP Urine allows the detection of GIP resulting from gastrointestinal degradation of ingested gluten in urine. The detection step is based on the reaction of the 33-mer-like immunogenic peptides of gluten present in the sample with the coloured conjugated (monoclonal anti-gliadin 33-mer antibody/red-coloured microsphere) previously loaded in the cassette. Complexes spread through the cassette by capillarity and interact with a second anti-gliadin 33-mer antibody immobilized on the membrane at the test zone. A red line at the test zone indicates a positive result while the absence of the red line indicates a negative result.

    Only the testing day.

  • Presence of IgA anti-tTG in blood

    The immunochromatographic test CeliacDetect allows the detection of IgA anti-tTG in blood samples. The detection step is based on the union of the IgA anti-tTG with anti human IgA antibodies labeled with colloidal gold and tTG (whose origin is the erythrocyte lysis in the dilution buffer). The complex would be bounded to the stable protein line (test line) by tTG. A red line at the test zone indicates a positive result while the absence of the red line indicates a negative result.

    Only the testing day.

Secondary Outcomes (1)

  • Presence of previous symptoms

Study Population

Population comprised of patients between 2 and 18 years old who are diagnosed with celiac disease or suspected to suffer the disease. They should have willingness to perform the study and ability to collect urine samples. Moreover, the patients or their legal guardians have to sign the informed consent.

You may qualify if:

  • Children and adolescents volunteers (2-18 years old).
  • Regular gluten consumption.
  • Willingness to perform the study and ability to collect urine samples.
  • The signing of the informed consent by the volunteer and his/her legal guardians.

You may not qualify if:

  • Related diseases or psychiatric alterations which do not recommend being included in the study as the researcher's consideration.
  • Lack of foreseeable collaboration.
  • Patients which do not provide samples or surveys in 70% of cases.
