Patients with celiac disease symptoms and anti-endomysium antibodies may have normal intestinal lining. Accurate diagnosis requires multiple biopsies and testing for immune activation to confirm gluten dependency.

Area of Science:

  • Gastroenterology
  • Immunology
  • Genetics

Background:

  • Celiac disease is a permanent gluten intolerance linked to HLA class II antigens.
  • Some patients present with celiac disease symptoms and anti-endomysium antibodies but normal mucosal architecture.
  • This study investigates a cohort of such patients.

Purpose of the Study:

  • To investigate patients with potential celiac disease who exhibit anti-endomysium antibodies but normal intestinal mucosa.
  • To assess the role of mucosal immune activation and HLA typing in these cases.
  • To determine gluten dependency in patients with atypical celiac disease presentation.

Main Methods:

  • Immunohistochemistry was used to detect mucosal immune activation.
  • HLA typing was performed on all patients.

  • Multiple biopsy specimens were analyzed, and in vitro gliadin challenge was conducted.

    • Main Results:

    • Mucosal immune activation was observed in patients on a gluten-containing diet, despite normal villous morphology in most samples.
    • Severe villous atrophy was found in one sample from 3 out of 6 patients.
    • Clinical and immunomorphologic features were strictly gluten-dependent, and immune response to gliadin was confirmed in vitro.

    Conclusions:

    • Gluten-sensitive celiac-like symptoms can occur in patients with anti-endomysium antibodies, normal mucosa, and non-typical HLA typing.
    • Multiple biopsies and assessment for immunologic activation are crucial for diagnosis.
    • A gluten-free diet trial and in vitro gliadin response testing can aid in diagnosing gluten-sensitive enteropathy.
