Omitting control biopsy in paediatric coeliac disease: a follow-up study.

AIM: To evaluate the practice of diagnosing coeliac disease with only one small-bowel mucosal biopsy in a selected group of children with suspected coeliac disease.

METHODS

A retrospective review of medical records and a follow-up interview of 102 children (65 girls, 37 boys) at diagnosis of coeliac disease. The inclusion criteria were age >18 months, increased levels of serum antitissue transglutaminase IgA antibodies and pathologic small-bowel mucosal biopsy. Anthropometric data were calculated for children 1.5-11 years of age.

RESULTS

The levels of serum antitissue transglutaminase IgA antibodies were either normal (92%) or slightly elevated (8%) in all children after 1 year on a gluten-free diet. The height-for-age Z score increased in 52 of 61 (85%) children, (median 0.26 SD, range -0.45 to 1.83 SD) and the weight-for-age Z score increased in 50 of 61 (82%) children (median 0.42 SD, range -0.77 to 2.24 SD). Sixty of 61 (98%) children showed normal or catch-up growth. Regression of symptoms after 1 year on a gluten-free diet was reported for 71 of 72 (98%) children.

CONCLUSION

We propose that a control biopsy is not necessary for the diagnosis of coeliac disease in these children.
