Pitfalls in diagnosing coeliac disease

Summary

Accurate coeliac disease diagnosis requires careful review of duodenal biopsies, especially in non-responsive cases. Morphometric analysis and repeat biopsies aid in confirming diagnosis when initial findings are equivocal or normal.

Area of Science:

  • Gastroenterology
  • Histopathology
  • Immunology

Background:

  • Coeliac disease diagnosis relies heavily on duodenal biopsy interpretation.
  • Refractory cases with equivocal histology present diagnostic challenges.

Purpose of the Study:

  • To identify diagnostic pitfalls in coeliac disease.
  • To recommend improved diagnostic and management strategies for refractory coeliac disease.

Main Methods:

  • Retrospective study of six patients with suspected refractory coeliac disease.
  • Peroral jejunal biopsies and morphometric analysis (villus height:crypt depth, enterocyte height, intraepithelial counts).

Main Results:

  • All patients had normal jejunal biopsies on gluten-free diet and after gluten challenge.

  • Morphometric analysis and intraepithelial counts were normal in follow-up biopsies.

    • Conclusions:

    • Initial misdiagnosis can stem from poor biopsy quality and sectioning.
    • Normal follow-up biopsies in non-responsive patients necessitate re-evaluation.
    • Recommendations include multiple, adequate, and correctly oriented biopsies, expert histopathological review, and consideration of morphometric analysis and jejunal biopsy for refractory cases.
