Coeliac disease screening among a large cohort of overweight/obese children.

Coeliac disease (CD) is a chronic, gluten-dependent enteropathy with a prevalence of approximately 1% in Western countries. Up to now, CD has been described only in sporadic cases of obesity. Our study aimed to evaluate retrospectively CD prevalence in a large series of overweight/obese children and adolescents. Among the 1527 overweight/obese children and adolescents consecutively evaluated, 17 (7 boys, 1.11%) were positive for serology and showed villous atrophy. In all of the patients with CD a well-balanced gluten-free diet was started, and a loss of weight rapidly obtained. Our study demonstrates that CD prevalence in overweight/obese children is similar to the general paediatric population in Italy.
