[Oxyntomodulin, a new hormonal marker of intestinal malabsorption syndromes].

Plasma oxyntomodulin-like immunoreactivity (OLI) concentrations were found to be significantly elevated in 6 patients with coeliac disease when compared with those observed in 38 healthy subjects. Furthermore, OLI hypersecretion is related to the degree of malabsorption. This marker could be used as a test for detection and follow-up of patients with malabsorptive disorders.
