Gastrointestinal hormone levels, including gastrin, cholecystokinin, and somatostatin, are significantly higher in young children compared to older children. These hormone concentrations decrease with age, potentially linked to growth and energy needs.

Area of Science:

  • Pediatric Endocrinology
  • Gastrointestinal Physiology
  • Developmental Biology

Background:

  • Newborns exhibit elevated gastrointestinal hormone levels compared to adults.
  • Hormonal profiles undergo significant changes during early childhood development.
  • Understanding these changes is crucial for assessing pediatric growth and metabolic health.

Purpose of the Study:

  • To investigate the correlation between age and plasma concentrations of gastrin, cholecystokinin, and somatostatin in healthy children aged 1-15 years.
  • To quantify the age-related decline in these key gastrointestinal peptides.
  • To explore potential physiological factors influencing these developmental hormonal shifts.

Main Methods:

  • Plasma samples were collected from healthy children aged 1-15 years.

  • Concentrations of gastrin, cholecystokinin, and somatostatin were measured using validated assays.
  • Statistical analysis was performed to determine correlations between age and hormone levels.

    • Main Results:

    • Hormone concentrations were approximately twice as high in children aged 1-2 years compared to those over 10 years.
    • Significant negative correlations were observed between age and plasma levels of all three studied hormones.
    • These findings indicate a clear age-dependent decrease in gastrin, cholecystokinin, and somatostatin during childhood.

    Conclusions:

    • Plasma levels of gastrin, cholecystokinin, and somatostatin decrease significantly with age in children from 1 to 15 years.
    • The observed age-related differences are hypothesized to be associated with the high growth rate and energy demands of early life.
    • Further research could elucidate the precise mechanisms linking growth, energy metabolism, and gastrointestinal peptide regulation in pediatric development.
