Gluten-related disorders

Gluten-related disorders are a heterogeneous group of clinical entities caused by intolerance to wheat, rye, and barley flour components. They occur in 3–5% of genetically predisposed persons and, based on pathogenic and clinical features, are classified into celiac disease, non-celiac gluten sensitivity, and wheat allergy. There are also specific entities such as dermatitis herpetiformis or gluten ataxia, which can occur either within the celiac disease or independently. This article based on the current knowledge shows the basic details of the pathogenesis, clinical expression, diagnosis, and treatment of these disorders.
