Elevated cholecystokinin concentrations in plasma in children with recurrent abdominal pain
1Department of Pediatrics, Huddinge Hospital, Sweden.
Insights
Children with recurrent abdominal pain show higher plasma cholecystokinin levels. Further research is needed to link this gastrointestinal hormone difference to their symptoms.
Area of Science:
- Pediatric Gastroenterology
- Endocrinology
- Gastrointestinal Physiology
Background:
- Recurrent abdominal pain is a common issue in children.
- Gastrointestinal hormones play a crucial role in digestive system function.
- Previous research has not fully explored the role of specific hormones in pediatric abdominal pain.
Purpose of the Study:
- To investigate plasma concentrations of gastrin, somatostatin, and cholecystokinin in children with recurrent abdominal pain.
- To compare hormone levels between children with and without recurrent abdominal pain.
- To explore potential links between gastrointestinal hormone levels and abdominal pain symptoms in children.
Main Methods:
- Radioimmunoassay (RIA) was used to measure plasma hormone levels.
- Blood samples were collected after an overnight fast from participants.
- Study included 44 children with recurrent abdominal pain and 36 age- and sex-matched controls.
Main Results:
- Children experiencing recurrent abdominal pain exhibited significantly higher plasma cholecystokinin concentrations compared to controls (p < 0.001).
- No significant differences were found in gastrin or somatostatin levels between the groups (data not shown).
Conclusions:
- Elevated plasma cholecystokinin may be associated with recurrent abdominal pain in children.
- The clinical significance of higher cholecystokinin levels in pediatric abdominal pain requires further investigation.
- This study highlights a potential biomarker for recurrent abdominal pain in pediatric patients.
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.
