Actual (reported)The goal of this clinical trial is to evaluate the tolerability of the oat cultivar Saul, previously characterized by low celiac disease-related immunoreactivity, in adults with celiac disease in sustained clinical and immunological remission The main question the study aims to answer is whether consumption of gluten-free oats of the Saul variety leads to changes in patient-reported symptoms and serological markers. Participants consumed50 g of gluten-free oat flakes daily for 14 consecutive days.

Actual (reported)Change in EMA-IgA
Change in endomysial antibody IgA (EMA-IgA) titers as a marker of celiac disease activity.
Day 1 (Baseline, start of oat consumption) and Day 15 (Post-intervention assessment)
Change in tTG-IgA
Change in tissue transglutaminase IgA (tTG-IgA, U/mL) levels as a marker of celiac disease activity.
Day 1 (Baseline, start of oat consumption) and Day 15 (Post-intervention assessment)
Change in DGP-IgG
Change in deamidated gliadin peptide IgG (DGP-IgG, U/mL) levels as a marker of celiac disease activity..
Day 1 (Baseline, start of oat consumption) and Day 15 (Post-intervention assessment)
Change in hs-CRP
Change in high-sensitivity C-reactive protein (hs-CRP, mg/L) levels as a marker of systemic inflammation.
Adult participants with celiac disease who are in clinical and immunological remission and have met all inclusion criteria. This arm evaluates the tolerance of gluten-free oats in the form of oat flakes, which participants consume daily for 14 consecutive days, with monitoring for clinical, immunological, and safety outcomes.
Variability in gluten-free oat tolerance in celiac disease in remission has been reported. Many clinical studies lack of specification of the oat cultivar used. In the present study, we evaluated the tolerability of the oat cultivar Saul, previously characterized by low CeD-related immunoreactivity
