[Dermatitis herpetiformis and other forms of wheat sensitivity].

backgroundWheat sensitivity is a collective term for several, especially gastrointestinal, diseases that occur as part of a hypersensitivity reaction after wheat consumption. The symptoms, which are mostly similar to those of irritable bowel syndrome, are often accompanied by skin lesions. In addition to celiac disease and dermatitis herpetiformis, the cutaneous manifestation of celiac disease, wheat sensitivity also includes nonceliac gluten sensitivity (NCGS), allergic nickel contact mucositis, wheat allergy, amylase-trypsin inhibitor intolerance, and fermentable oligosaccharides, disaccharides, monosaccharides, and polyols (FODMAP) intolerance.

objectivesThis review article aims to provide an overview of the clinical, especially dermatological and gastrointestinal features of the different forms of wheat sensitivity. Diagnosis and therapeutic management are also discussed. MATERIALS AND

methodsA selective literature search was carried out with evaluation of our own clinical data.

resultsThe skin lesions in dermatitis herpetiformis are very disease-specific. In contrast, wheat allergy often shares signs and symptoms with many other diseases. Other forms of wheat sensitivity cause primarily gastrointestinal abnormalities, but extra-intestinal manifestations can also occur. Their diagnosis is often complex and requires cross-disciplinary collaboration with experts in gastroenterology. The therapy consists of a wheat- or gluten-free diet.

conclusionsKnowledge of the different and frequently occurring dermatological signs of wheat sensitivity is of great importance, because dermatological manifestations associated with gastrointestinal pathology, intolerance reactions, and allergies appear more and more frequently.
