Gluten-free Diet Monitoring in Urine

Early Phase 1
Completed
Conditions
Celiac Disease
Interventions
Device: Non-invasive lateral flow test for monitoring gluten intake
Behavioral: gluten-free diet (GFD)
Behavioral: gluten-containing diet
Registration Number
NCT02344758
Lead Sponsor
University of Seville
Brief Summary

The purpose of this study is to develope a novel method to determine gluten intake and to check gluten-free diet adherence in celiac patients by detection of gluten immunogenic peptides in urine.

Detailed Description

To date, the mainstay of the management of CD is a strict life-long adherence to gluten-free diet (GFD). Follow-up monitoring of the improvement of patients on GFD is essential to assess symptomatic recovery and to monitor complications, as well as to assist patients with dietary compliance. However, practical methods to monitor diet compliance and to detect the origin of an outbreak of celiac clinical symptoms are not available.

In this study, we have overcome these challenges and shown the feasibility of measuring gluten immunogenic peptides (GIP) in urine samples in healthy and celiac individuals by solid phase extraction and estimating the peptide concentrations with a reader of anti-GIP moAb immunochromatographic strips (IC-strips).
