Background & Aims: Celiac disease (CD) has been associated with several genetic disorders, but has not been associated with hereditary fructose intolerance (HFI). Methods: We identified CD in 4 female patients affected by HFI from among 38 Italian HFI patients. Results: Three of these patients were children in whom the CD-associated signs were hypertransaminasemia, failure to thrive, low weight, and short stature, whereas the adult patient had protracted diarrhea notwithstanding a fructose-free diet. The incidence of CD in our group of HFI patients was higher (>10%) than in the general population (1%-3%) (P <.02). Conclusions: The possibility of an association between these 2 gastrointestinal disorders is important, particularly in the management of HFI patients with persisting symptoms.
