    Increased immunoglobulin E (IgE) plasmocytes in small bowel biopsies indicate potential cow's milk allergy in children. Normal levels were observed in children on a milk-free diet, suggesting IgE’s role in diagnosing milk allergy.

    Area of Science:

    • Immunology
    • Gastroenterology
    • Pediatrics

    Context:

    • Assessing small bowel injury in children.
    • Investigating the role of immunoglobulin E (IgE) in pediatric gastrointestinal disorders.
    • Utilizing immunoperoxidase techniques for cell identification.

    Purpose:

    • To quantify IgE-positive plasmocytes in the small bowel mucosa of children with suspected injury.
    • To determine if elevated IgE plasmocytes correlate with specific conditions like cow's milk allergy.
    • To evaluate IgE plasmocyte levels in children with cow's milk allergy on a restricted diet.

    Summary:

    • Small bowel biopsy tissues from 24 children were analyzed for IgE plasmocytes using immunoperoxidase staining.
    • Significantly higher IgE plasmocyte counts (mean 143 cells/mm²) were found in 3 children with diagnosed cow's milk allergy.

  • Other patients and 2 children with cow's milk allergy on a milk-free diet exhibited low IgE plasmocyte counts (mean 4 cells/mm²).

    • Impact:

    • Suggests elevated IgE plasmocytes in small bowel biopsies may serve as a biomarker for cow's milk allergy in children.
    • Highlights the potential diagnostic value of IgE plasmocyte enumeration in pediatric gastroenterology.
    • Provides evidence for the reversibility of IgE plasmocyte elevation upon dietary intervention for cow's milk allergy.
