Role of Glucagon-Like Peptide-1 in Postprandial Hypoglycemia After Nissen Fundoplication: Studies With the GLP-1 Receptor Antagonist Exendin-(9-39)
In Brief
A clinical study evaluating Exendin-(9-39) and Vehicle for Postprandial Hypoglycemia. Completed, enrolled 7 participants across 1 site.
Detailed Summary
It has been proposed that the rapid gastric emptying of carbohydrate containing fluids into the intestine causes hyperglycemia followed by reactive hypoglycemia. The investigators have shown that glucagon-like peptide-1 (GLP-1) secretion in response to a glucose load is increased in children with Post-prandial hypoglycemia (PPH). This is a proof of concept study to investigate the causative role of GLP-1 in the pathophysiology of PPH after fundoplication by evaluating the effects of GLP-1 receptor antagonism on metabolic variables after a mixed meal. Hypothesis: In children with post-prandial hypoglycemia after fundoplication, antagonism of the GLP-1 receptor by exendin-(9-39) will elevate nadir blood glucose levels after a meal challenge and prevent post-prandial hypoglycemia.
