Reaginic hypersensitivity in ulcerative colitis.

D P Jewell, S C Truelove

    Gut
    |November 1, 1972
    PubMed
    Summary
    This summary is machine-generated.

    This study found no evidence of reaginic antibody-mediated milk protein allergy in ulcerative colitis patients. However, a higher incidence of atopy suggests a general susceptibility to allergic responses.

    Area of Science:

    • Immunology
    • Gastroenterology

    Background:

    • Ulcerative colitis (UC) pathogenesis is complex.
    • Investigating potential triggers like food allergies is crucial for understanding UC.
    • Reaginic hypersensitivity, often IgE-mediated, is a common allergic response.

    Purpose of the Study:

    • To investigate reaginic hypersensitivity to cow's milk proteins in ulcerative colitis patients.
    • To determine the frequency of atopic diseases in UC patients.
    • To explore the role of milk allergy in UC pathogenesis.

    Main Methods:

    • Intradermal skin testing with milk proteins.
    • Assessing circulating IgE-specific antibodies to milk proteins.
    • Comparing atopic disease prevalence in UC, Crohn's disease, and control groups.

    Main Results:

    • Intradermal tests for milk protein hypersensitivity were common but not specific to UC.
    • No IgE-specific antibodies to milk proteins were detected in UC patients.
    • Atopic diseases were significantly more frequent in UC (15.7%) and Crohn's disease (13.3%) patients than in controls (1.2%).

    Conclusions:

    • Reaginic antibodies do not appear to mediate milk protein allergy in ulcerative colitis.
    • The increased frequency of atopy in UC patients suggests a general susceptibility to allergic reactions.
    • Further research is needed to elucidate the role of atopy in inflammatory bowel disease pathogenesis.
