Plasma enteroglucagon in the control of childhood celiac disease.

Abstract

To study whether or not plasma enteroglucagon reflects changes of the small intestinal mucosa during different phases of celiac disease, we studied fasting and postprandial concentrations of plasma enteroglucagon, as well as small intestinal mucosa morphology, in children with celiac disease and in a reference group of children without gastrointestinal disorders. The children with celiac disease were studied before dietary treatment, during gluten-free diet, and during gluten challenge. In untreated celiac children we found high mean basal and postprandial plasma enteroglucagon concentrations compared with the reference group (p less than 0.001). After a gluten-free diet period of 0.2-4.5 years (mean, 1.0 year), when the small intestinal histology was normal or only mildly abnormal, there was a decrease of both mean basal plasma enteroglucagon concentration (from 81 to 17 pmol/L; p less than 0.001) and mean postprandial plasma enteroglucagon concentration (from 129 to 39 pmol/L; p less than 0.001). During a subsequent gluten challenge, which resulted in a mucosal relapse, there was a rise in mean postprandial plasma enteroglucagon concentration (from 39 to 74 pmol/L; p less than 0.005), although there was a substantial overlap in values from treated and challenged patients. These findings suggest that plasma enteroglucagon levels, particularly after a mixed meal, are correlated with the small intestinal mucosal morphology in childhood celiac disease. Determination of plasma enteroglucagon may facilitate the control of the dietary adherence during gluten-free diet and may in some children indicate mucosal relapse during gluten challenge. Thus, the number of control biopsies may be reduced.
