Evaluating biomarkers in patients with not-celiac wheat sensitivity

Official title: Not-celiac Wheat Sensitivity (NCWS) in Patients With Irritable Bowel Syndrome. Randomized Double-Blind Placebo-Controlled Trial (Wheat vs Placebo) for Bio-markers Identification of NCWS and Understanding Its Pathogenetic Mechanisms.

Run by University of Palermo · NCT01762579 · Data updated 2026-11-12

This study is trying to understand how the body reacts to wheat in adults with symptoms that get better on a gluten-free diet and worse when they eat gluten, to help clarify not-celiac wheat sensitivity.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 18-65 with IBS-like symptoms that improve on a gluten-free diet and worsen on a gluten-containing diet.

Probably not a fit

Patients diagnosed with celiac disease, wheat allergy, or other significant gastrointestinal conditions will not benefit from this study.

What this trial studies

This study aims to assess the biochemical, immunological, and histological characteristics of patients experiencing symptoms related to not-celiac wheat sensitivity (NCWS). Participants will include adults aged 18-65 who have IBS-like symptoms that improve on a gluten-free diet and worsen with gluten consumption. The study will involve testing for celiac disease and wheat allergy to ensure accurate diagnosis. By understanding the immune response to wheat, the researchers hope to clarify the nature of NCWS and its impact on health.

Why it matters

Potential benefit: If successful, this study could lead to better diagnosis and management of not-celiac wheat sensitivity, improving quality of life for affected patients.

How similar studies have gone: While the concept of not-celiac wheat sensitivity is gaining attention, this specific approach to understanding its biomarkers is relatively novel and has not been extensively tested in previous studies.
