Is peptic ulceration a hormonal disease?

R G Fiddian-Green

    Lancet (London, England)
    |January 8, 1977
    PubMed
    Summary

    Peptic ulcers are not solely caused by excess acid. An antral factor, likely abnormal gastrin (G17) release, contributes to ulcer development and persistence, requiring its removal for a cure.

    Area of Science:

    • Gastroenterology
    • Pathophysiology
    • Endocrinology

    Background:

    • Peptic ulcer disease pathogenesis is complex, not solely explained by abnormal acid secretion.
    • Ulcers can occur in individuals with normal acid secretion levels.
    • Duodenal and gastric ulcers share a common underlying cause.

    Purpose of the Study:

    • To investigate the common cause of duodenal and gastric ulcers.
    • To differentiate between ulcer healing mechanisms and disease cure.
    • To identify and characterize an 'antral factor' involved in ulcer pathogenesis.

    Main Methods:

    • Analysis of acid secretion capacity in ulcer patients.
    • Evaluation of mechanisms involved in ulcer healing versus disease resolution.
    • Postulation of gastrin (G17) as a key antral factor.

    Main Results:

    • Ulcer location is determined by individual acid secretion capacity.
    • Reducing acid secretion heals ulcers but doesn't cure the disease.
    • Abnormal gastrin (G17) release in gastric juice is implicated in ulcer patients and gastrinomas.
    • Impaired response to duodenal acidification and reduced secretin release contribute to abnormal gastrin release.
    • Abnormal gastrin stimulation may lead to antral G-cell hyperplasia and gastrinomas.

    Conclusions:

    • An antral factor, specifically abnormal gastrin (G17) release, is crucial for ulcer cure.
    • Abnormal gastrin secretion can lead to uncontrolled acid production and bile exposure, causing ulcers.
    • Understanding gastrin's role offers insights into treating persistent peptic ulcer disease.
