Gastrointestinal Peptide Profile in Children with Celiac Disease

Le résumé fourni par la source

In order to investigate if a plasma profile of gastrointestinal peptides reflects changes in jejunal mucosa in celiac disease, we studied basal and postprandial plasma levels of gastrin, secretin, somatostatin, vasoactive intestinal polypeptide (VIP), and neurotensin in children with untreated and treated celiac disease and in a control group of children. Basal and 30-min postprandial secretin concentrations were statistically significantly lower in untreated celiac children compared to both treated celiac (p less than 0.01 and p less than 0.05, respectively) and control children (p less than 0.001). Plasma secretin levels 30 min after a breakfast meal were also statistically significantly lower (p less than 0.001) in treated celiac children with respect to the control group. In both untreated and treated celiac groups, basal and postprandial plasma levels of somatostatin and VIP were statistically significantly decreased (p less than 0.001) compared to control children. Moreover, there was a significant rise in postprandial levels of neurotensin after a breakfast meal in untreated celiac children. On the contrary, there was no rise of neurotensin in healthy children. These findings seem to indicate that determination of plasma profile of gastrointestinal peptides in children with celiac disease may be useful in monitoring the development of this disease and, thus, the number of jejunal biopsies could be decreased.
