Celiac disease is manifestation of intolerance to gluten better known, but not the only existing. Through the skin can also manifest hypersensitivity to this component of the diet is what is called dermatitis herpetiformis , also known as disease Durhing Brocq . ” It is a disease autoimmune which develops gluten intolerance and consisting of the appearance of lesions is called vesicular papules, with sobreelevada, bullous appearance , ” says Teresa Truchuelo, a dermatologist at the Vithas Hospital Our Lady of America and Vithas International .
Both people who have celiac disease, such as dermatitis herpetiformis, have some genetic predisposition to suffer from such diseases, however, it is clear that ” only 5 percent of celiac patients develop this skin condition throughout their lives “said Truchuelo. However, the expert stresses the importance of ” differential diagnosis because this type of dermatitis, in many cases go unnoticed or be confused with eczema, scabies or other bullous diseases.”
Lesions causing skin appear frequently in extension areas as elbows, knees and buttocks and sometimes on scalp . It is usual to begin to develop in the third decade of life and rarely appears in children under 3 years. Dermatitis herpetiformis to treat the bottom line is avoid eating gluten “is essential to eliminate from the diet wheat, rye and barley; itself can be taken oats, maize and rice. Once gluten is removed, the skin lesions disappear , “says Truchuelo.
How to diagnose dermatitis herpetiformis
To diagnose this disease is not enough clinical examination, it is necessary to perform a biopsy of the affected skin . As explained dermatologist, “it is necessary to apply a specific technique in the study of biopsy, which is the immunofluorescence , used to detect antibodies generated in this disease. It is to make these antibodies that are generated by intolerance to gluten and are responsible for the formation of skin lesions. ” If it is confirmed that it is dermatitis herpetiformis and the patient is not diagnosed with celiac disease, “it will be necessary to rule out the disease by relevant evidence”. Experts stress the importance of making a diagnosis of dermatitis herpetiformis certainty so early , since clinical refers to make a gluten – free diet. But, clarify, referral may take a few months , so that in some cases may be associated oral treatment with dapsone, “under medical supervision to avoid possible side effects.”
