What this trial studies

This study investigates the tolerability of various types of wheat bread in individuals who may have non-celiac wheat sensitivity (NCWS). It employs a double-blind placebo-controlled food challenge and confocal laser endomicroscopy (CLE) to assess the intestinal mucosal response to different bread types. The goal is to improve the understanding and diagnosis of NCWS, which is often misdiagnosed due to inconsistent criteria. Participants will adhere to a prescribed diet while their gastrointestinal symptoms are monitored over the study period.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 to 75 with chronic gastrointestinal symptoms and a history of wheat sensitivity.

Not a fit: Patients with diagnosed celiac disease or wheat allergy will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to better diagnostic methods and dietary recommendations for individuals suffering from wheat sensitivity.

How similar studies have performed: While studies on gluten and wheat sensitivity exist, this specific approach using CLE and various bread types is relatively novel.
