 Dermatitis herpetiformis generally responds well to medication and a strict gluten-free diet.It is an autoimmune disease, however, and thus individuals with DH are more likely to develop other autoimmune conditions such as thyroid disease, insulin-dependent diabetes, lupus erythematosus, Sjögren's syndrome, sarcoidosis, vitiligo, and alopecia areata.There has been an association of non-Hodgkin lymphoma in individuals who have dermatitis herpetiformis, although this risk decreases to less than the population risk with a strict gluten-free diet.
