[Immunity in patients with peptic ulcer].

    Summary

    Patients with ulcer disease exhibit immune system dysregulation due to food antigens. This leads to an immune-complex reaction in the gastroduodenal area, potentially causing ulcer formation.

    Area of Science:

    • Immunology
    • Gastroenterology
    • Pathophysiology

    Background:

    • Ulcer disease is a common condition with complex etiologies.
    • The role of immune responses in ulcer pathogenesis requires further elucidation.

    Purpose of the Study:

    • To evaluate unspecific defense and immunological factors in patients with ulcer disease.
    • To propose a hypothesis for ulcer formation based on immune responses to food antigens.

    Main Methods:

    • Evaluation of immunological parameters in 520 patients with ulcer disease.
    • Assessment of unspecific defense mechanisms.

    Main Results:

    • Patients showed excessive release of food antigens, particularly partially split proteins.
    • Increased secretion of IgA, elevated IgG in blood, inhibited T-cell immunity, and increased complement consumption were observed.

    Conclusions:

    • Food antigens entering the body can lead to sensitization.
    • An immune-complex reaction, similar to the Arthus phenomenon, in the gastroduodenal zone may cause ulcer formation.
