Celiac disease and short stature--not always cause and effect.

Four children with familial short stature were diagnosed with celiac disease (CD) by positive serology for antigliadin and antiendomysial antibodies and characteristic intestinal biopsy findings. These patients complied well with their diet as evidenced by their parents' reports, increase in weight standard deviation scores in all but one child, and reversion to seronegativity for antigliadin and antiendomysial antibodies in all four. However, typical catch-up for linear growth did not occur. In our view, the poor response of linear growth is evidence that the original stunting was not due to CD. Since the advent of sensitive tests for antiendomysial antibodies, many asymptomatic children have been diagnosed as having CD. Some of these children are short and despite a history of familial short stature their growth stunting may be wrongly attributed to CD. This report highlights this new problem and emphasizes the need for caution when predicting growth response to a gluten-free diet.
