BACKGROUND: @entity66 may easily mimic symptoms which are parts of the criteria used for diagnosing @entity1744 . AIM: To find the frequency of @entity66 among @entity1 diagnosed as @entity1744 . METHODS: During a period of one year, @entity1744 @entity1 referred to a university clinic in Tehran were studied. For each @entity1 , an asymptomatic sibling was enrolled as control. Serological tests for @entity66 were performed in all @entity1 and controls. If positive, duodenal biopsy was performed to confirm the diagnosis. @entity1 subsequently diagnosed as @entity66 were placed on a gluten free diet and re-evaluated after 6 months. RESULTS: One hundred and five cases of @entity1744 and 105 controls were enrolled. @entity66 was diagnosed in 12 of the @entity1744 @entity1 and none of the controls. Eleven @entity66 @entity1 adhered to a gluten free diet. After 6 months, all 11 @entity1 had significant improvement in symptoms and three were totally asymptomatic. Six allowed repeated endoscopy after 6 months of gluten free diet, of which five showed improvement in histological findings. CONCLUSIONS: @entity66 is a common finding among @entity1 labelled as @entity1744 . In this sub-group, a gluten free diet may lead to a significant improvement in symptoms. Routine testing for @entity66 may be indicated in all @entity1 being evaluated for @entity1744 .
