Extraintestinal (dermatological) manifestations of malabsorption syndrome and celiac disease

This review presents information on the prevalence, pathogenesis, clinical manifestations, diagnosis and treatment of Duhring’s dermatitis herpetiformis. Although the disease was first clinically described in 1884 by the American dermatologist L.A. Duhring, the study of its pathogenesis and the search for prognostic markers of its occurrence continue. Against the background of a significant expansion of ideas about gluten-dependent diseases and conditions, views on the mechanisms of autoimmune skin damage in dermatitis herpetiformis are detailed. A strong association with hereditary predisposition through the major human leukocyte histocompatibility complex (HLA) DQ2 and DQ8, and a role of epidermal transglutaminase as a major autoantigen in dermatitis herpetiformis are shown. The hypotheses explaining the decline in the incidence of dermatitis herpetiformis in recent decades against the background of increased and more effective serological screening and the resulting earlier diagnosis of celiac disease are commented on. A typical clinical picture of dermatitis herpetiformis, in which erythematous papules, plaques, vesicles are seen, usually clustered on the flexural surfaces of the extremities. Secondary elements are erosions, excoriations and crusts due to rupture of blisters and due to scratching caused by intense itching. A generally favourable prognosis for life and disease is shown with a gluten-free diet and the use of dapsone, glucocorticoids and, if these are ineffective, immunosuppressants. The authors describe a clinical case of the disease in an adolescent girl with a typical clinical history and characteristic rashes on the extensor surfaces of the limbs. The authors show that drug therapy without a gluten-free diet cannot be considered effective, and that the diet for dermatitis herpetiformis, like that for celiac disease, is lifelong. The growing understanding of gluten-associated pathology, which includes dermatitis herpetiformis, in recent decades has led to an intensive search for diagnostic and prognostic markers, as well as the development of ways to correct this group of diseases, including those not related to the lifelong elimination of cereal prolamines.
