Silent celiac disease is frequent in the siblings of newly diagnosed celiac patients.

Background/aims: Celiac disease is caused by environmental and genetic factors, and the relatives of celiac patients are at higher risk of developing celiac disease than the general population. This prospective study evaluates the prevalence of celiac disease in the asymptomatic siblings of celiac patients.

Methods: Forty-eight siblings (22 males; mean age 13 years) of 39 celiac children (20 males; mean age 4 years), and 120 siblings (55 males; mean age 33 years) of 55 adult celiac patients (12 males; mean age 31 years) were serologically screened for celiac disease.

Gluten intolerance: gender- and age-related differences in symptoms.

Objective: Gluten intolerance is a common, immunologically mediated disorder with a widely variable clinical presentation that affects genetically predisposed subjects. Women seem to be more frequently affected although data on sex differences are poor. In this study the prevalence of different clinical pictures according to sex and age is analysed in a large series of patients.
