    Severe tropical malabsorption alters gut hormone levels, showing elevated motilin and enteroglucagon but reduced gastric inhibitory polypeptide and insulin release post-meal. This distinct hormonal pattern offers insights into malabsorption pathophysiology.

    Area of Science:

    • Gastroenterology
    • Endocrinology
    • Human Physiology

    Background:

    • Tropical malabsorption is a severe condition affecting nutrient absorption.
    • Gut hormones play crucial roles in digestion and nutrient regulation.
    • Understanding hormonal imbalances is key to addressing malabsorption.

    Purpose of the Study:

    • To investigate the specific patterns of gut hormone release in patients with severe tropical malabsorption.
    • To compare the gut hormone profiles of these patients with healthy controls.
    • To elucidate the pathophysiological mechanisms underlying tropical malabsorption through hormonal analysis.

    Main Methods:

    • Measurement of various gut hormone concentrations (motilin, enteroglucagon, gastric inhibitory polypeptide, insulin) in plasma.

  • Administration of a standardized test breakfast to participants.
  • Comparison of hormone levels between eight patients with severe tropical malabsorption and 12 healthy controls.

    • Main Results:

    • Patients exhibited significantly elevated basal plasma motilin and enteroglucagon concentrations.
    • Postprandial release of gastric inhibitory polypeptide and insulin was significantly reduced in patients.
    • The observed gut hormone release pattern in tropical malabsorption differs from that seen in coeliac disease.

    Conclusions:

    • Gut hormone dysregulation is a significant feature of severe tropical malabsorption.
    • Specific hormonal profiles, including elevated motilin and enteroglucagon and reduced GIP/insulin, characterize this condition.
    • Hormonal measurements provide novel insights into tropical malabsorption pathophysiology and potential therapeutic targets.
