Past, present and future of non-invasive tests to assess gluten exposure, celiac disease activity, and end-organ damage

Although many biomarkers have been proposed and several are in widespread clinical use, there is no single readout or combination of readouts that correlates tightly with gluten exposure, disease activity or end-organ damage in treated celiac disease patients. Challenges to developing and evaluating better biomarkers include significant interindividual variability related to immune amplification of gluten exposure and how effects of immune activation are manifest. Furthermore, the current “gold standard” for assessment of end-organ damage, small intestinal biopsy, is itself highly imperfect, such that a marker that is actually a better reflection of the “ground truth” may indeed appear to perform poorly.
