[The problem of functional achlorhydria]

H Kinzlmeier, H Freitag

    Zeitschrift Fur Gastroenterologie
    |July 1, 1976
    PubMed
    Summary
    This summary is machine-generated.

    Functional achlorhydria can persist in the gastric mucosa even after maximal stimulation. Submaximal stimulation does not reliably correlate with the gastric mucosa

    Area of Science:

    • Gastroenterology
    • Physiology

    Background:

    • Achlorhydria, the absence of hydrochloric acid in gastric secretions, can be associated with various gastric conditions.
    • Understanding the relationship between gastric mucosal morphology and acid secretion is crucial for diagnosis and treatment.

    Purpose of the Study:

    • To investigate whether achlorhydria can persist in anatomically intact gastric mucosa after maximal stimulation.
    • To evaluate the concept of functional achlorhydria versus structural causes.
    • To assess the correlation between gastric mucosal histology and chloric acid secretion under different stimulation levels.

    Main Methods:

    • Studied chloric acid secretion in 101 cases after submaximal and maximal stimulation.
    • Utilized histamine chloride and pentagastrine for maximal stimulation.

  • Correlated acid secretion with histological examination of gastric mucosal biopsies.

    • Main Results:

    • No correlation was found between morphology and acid secretion in intact gastric mucosa after submaximal stimulation.
    • Submaximal stimulation showed correspondence to histology in only 18 out of 28 cases.
    • Maximal stimulation revealed persistent achlorhydria in one case with histologically intact mucosa, supporting functional achlorhydria.
    • More congruence between histology and secretion was observed in atrophic gastric mucosa.

    Conclusions:

    • Persistent achlorhydria after maximal stimulation suggests a functional basis.
    • Submaximal stimulation protocols lack sufficient correlation with gastric mucosal morphology.
    • Discrepancies are more pronounced in histologically normal gastric mucosa compared to atrophic mucosa.
