Biomarkers for Intestinal Permeability

January 25, 2021 updated by: Stephan C. Bischoff, MD, Professor, University of Hohenheim

Pilot Study: Validation of Easy-to-measure Biomarkers for Intestinal Permeability in Human Trials

This study aims to find easy-to-measure biomarkers of intestinal permeability as surrogate markers for effortful "gold standard" methods.

Study Overview

Detailed Description

This study aims to find easy-to-measure biomarkers of intestinal permeability as surrogate markers for effortful "gold standard" methods. In healthy volunteers potential biomarkers for intestinal permeability as well as an established "gold standard" method for intestinal permeability (urinary lactulose/mannitol excretion) will be measured at one time point. Using correlation analyses, potential associations will be assessed and potential biomarkers will be addressed and discussed.
