Improving food allergy diagnosis using mucosal IgE levels

Improving the Diagnosis of Food Allergy and Food Intolerance by Determining Mucosal IgE and Inflammatory Markers and Validating With Intestinal in Vitro Organoids

Not applicable Interventional University of Erlangen-Nürnberg Medical School · NCT05259826

This study is testing a new way to diagnose food allergies by looking at specific markers in gut tissue to see if it helps people get better answers about their symptoms.

What this trial studies

This study aims to enhance the diagnosis of food allergies and hypersensitivities by analyzing mucosal IgE levels and other inflammatory parameters from intestinal biopsies. Researchers will correlate these findings with serum values and disease status, while also culturing organoids from duodenal tissue to identify relevant biomarkers in response to major food allergens. The study addresses the challenges of diagnosing gastrointestinal-mediated food allergies, which often present similar symptoms to other food intolerances. By utilizing advanced techniques, the study seeks to provide a more accurate diagnostic approach for affected patients.

Who should consider this trial

Good fit: Ideal candidates include patients with suspected food allergies or hypersensitivities and healthy controls requiring endoscopic diagnostics.

Not a fit: Patients who are pregnant will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to more accurate diagnoses of food allergies, reducing the reliance on elimination diets and improving patient outcomes.

How similar studies have performed: Previous pilot studies have shown promising results in identifying mucosal IgE levels as a potential diagnostic marker for food intolerances, indicating a novel approach.
