Serum pancreatic polypeptide and glucagon immunoreactivity in fasting healthy and diabetic children
Insights
Serum pancreatic polypeptide (hPP) and glucagon immunoreactivity (IRG) levels decrease with age in healthy children. Diabetic children show elevated IRG and altered hormone levels, losing age-dependent patterns.
Area of Science:
- Endocrinology
- Pediatrics
- Metabolic Research
Background:
- Pancreatic polypeptide (hPP) and glucagon immunoreactivity (IRG) are key hormones involved in metabolic regulation.
- Understanding their levels and age-related changes is crucial, especially in pediatric populations.
- Altered hormonal profiles are often observed in children with diabetes mellitus.
Purpose of the Study:
- To investigate serum hPP and plasma IRG concentrations in healthy children.
- To compare hormone levels and their age-dependency in diabetic children versus healthy controls.
- To explore the relationship between hormone levels and diabetes duration.
Main Methods:
- Measurement of serum hPP and plasma IRG concentrations in a cohort of children.
- Analysis of hormone levels in relation to age and health status (diabetic vs. healthy).
- Statistical evaluation of hormone levels, age-dependency, and correlation with diabetes duration.
Main Results:
- Normal children exhibited a wide range of hPP (45-525 pg/ml, mean 185 pg/ml) and showed age-dependent decreases in both hPP and IRG.
- Diabetic children presented significantly higher plasma IRG and slightly elevated hPP compared to healthy children.
- The age-dependent decline of these hormones was absent in diabetic children, with no correlation found between hPP/IRG and diabetes duration.
Conclusions:
- Serum hPP and plasma IRG levels exhibit distinct age-related patterns in healthy children.
- Diabetes in children significantly alters these hormonal profiles, diminishing their age-dependency.
- The findings highlight metabolic dysregulation in pediatric diabetes and suggest potential roles for hPP and IRG in the condition.
Abstract:
Serum pancreatic polypeptide (hPP) concentrations ranged in normal children from 45 pg/ml to 525 pg/ml with mean value at 185 +/- 49 pg/ml. Both hPP and glucagon immunoreactivity (IRG) levels showed age-dependent decrease during childhood. In diabetic children plasma IRG concentrations were significantly increased in comparison with the healthy subjects while hPP concentrations were only slightly elevated. The age dependence of the hormones levels was completely effaced in diabetics. No significant serum hPP norm IRG values dependence on the duration of diabetes was found. IRG/hPP relations correlated with age in healthy children despite those in diabetic ones.
