title: Elevated cholecystokinin concentrations in plasma in children with recurrent abdominal pain.
abstract: The objective of the present study was to measure plasma concentrations of the gastrointestinal hormones gastrin, somatostatin and cholecystokinin in plasma of children with recurrent abdominal pain, since these hormones affect gastrointestinal function. Forty-four children (7-16 years old) with recurrent abdominal pain and 36 control children (matched for age and sex) participated in the study. In a blood sample collected after an overnight fast, gastrin, somatostatin and cholecystokinin concentrations were measured by radioimmunoassay. The children with recurrent abdominal pain had higher plasma cholecystokinin levels (p < 0.001) than the controls. Whether or not this aberration is related to the clinical symptoms of children with recurrent abdominal pain remains to be established.
