Giardiasis with total villous atrophy.

J D Levinson, L J Nastro

    Gastroenterology
    |February 1, 1978
    PubMed
    Summary
    This summary is machine-generated.

    Symptomatic giardiasis can cause total villous atrophy, a finding previously undescribed in patients without celiac disease or immunodeficiency. Treatment with metronidazole normalized the small intestine biopsy, even with continued gluten exposure.

    Area of Science:

    • Gastroenterology
    • Parasitology
    • Internal Medicine

    Background:

    • Giardiasis is a common intestinal infection caused by Giardia lamblia.
    • Diagnosis typically involves stool examination or duodenal aspiration.
    • Villous atrophy is a known complication of celiac disease and certain immunodeficiencies.

    Observation:

    • A patient presented with symptomatic giardiasis following travel to the Soviet Union.
    • Duodenal aspiration confirmed the diagnosis of giardiasis.
    • Small intestinal biopsy revealed total villous atrophy.

    Findings:

    • The observed total villous atrophy was not associated with celiac sprue or gastrointestinal immunodeficiency syndrome.
    • This represents a novel finding in the context of giardiasis.

  • Following a single course of metronidazole, the patient's small intestinal biopsy normalized.
  • The biopsy remained normal despite subsequent gluten exposure, suggesting a resolution of the villous atrophy.

    • Implications:

    • Giardiasis should be considered in the differential diagnosis of unexplained villous atrophy.
    • Metronidazole appears effective in resolving giardiasis-induced villous atrophy.
    • Further research is warranted to understand the mechanism of villous atrophy in giardiasis and its resolution.
