Abstract
AbstractObjectivesThis study aimed to evaluate the contributions of the Adapted Celiac Dietary Adherence Test (CDAT) and the Rapid Urinary Gluten Detection Test (u‐GIP) in assessing gluten‐free diet adherence in children and adolescents with celiac disease.MethodsFifty‐four celiac patients from two pediatric gastroenterology outpatient clinics affiliated with university hospitals were evaluated. The original CDAT was adapted for children through a transcultural process, and the original cutoff point was adopted to define adherence. A single examiner carried out the u‐GIP test in fresh urine samples. Sociodemographic and clinical factors and family food security status were also evaluated.ResultsA total of 88.9% of participants (confidence interval [CI]: 77.4–95.8; p<0.001) adhered to the gluten‐free diet, as determined by the adapted CDAT score, while 87.0% (CI: 75.1–94.6; p<0.001) had negative u‐GIP results. Among the 48 children adhering to the CDAT, six exhibited positive u‐GIP results in a urine sample. Of the six nonadherent participants, only one had a positive u‐GIP result. Notably, none of the children and adolescents with celiac disease who tested positive for u‐GIP reported symptoms on the day of testing, and their growth rates remained stable.ConclusionsEven celiac children and adolescents adhering to the CDAT questionnaire may show a positive u‐GIP in a single measurement without accompanying symptoms or growth impairment. The u‐GIP could be helpful in complementary tests in specific situations, such as for patients who exhibit compliant behavior but still experience symptoms or maintain persistent positive serology.
