Tiny gluten doses spark immune changes in kids with celiac disease
NCT ID NCT07362654
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at how the immune system of children with celiac disease responds to tiny, controlled amounts of gluten. About 51 kids on a strict gluten-free diet will get either a placebo, a small dose (50 mg), or a larger dose (5 g) of gluten daily for three days. Researchers will analyze blood, stool, and urine samples to see if even tiny gluten exposures cause measurable immune changes, which could lead to better tests and care for celiac disease.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Age 8 to 14 years at study entry. * Diagnosis of celiac disease according to ESPGHAN 2020 criteria. * At least 18 months on a strict gluten-free diet (GFD). * Adequate adherence to the GFD, demonstrated by negative fecal gluten immunogenic peptides (GIP) prior to inclusion. * Asymptomatic from a gastrointestinal perspective in the preceding weeks. * Ability to swallow the gluten/placebo preparation. * Written informed consent from parents/legal guardians and assent from the child. Exclusion Criteria: * Obesity defined as BMI ≥ 95th percentile according to WHO criteria. * Diagnosed inflammatory bowel disease or diabetes mellitus. * Acute infectious illness at the time of inclusion. * Chronic hepatic, pulmonary, renal, or rheumatologic disease. * History of severe acute reactions to accidental gluten ingestion. * Use of oral corticosteroids or immunosuppressive therapy in the previous 3 months. * Any condition that, in the opinion of the investigators, may contraindicate participation or compromise study integrity.
