title: [Dermatitis herpetiformis (author's transl)].
abstract: Detailed investigations of 9 patients with dermatitis herpetiformis are presented. In all cases cutaneous lesions were controlled by dapsone alone or by dapsone and gluten free diet. Granular IgA deposits were found in 7 patients, linear IgA deposits in one, and C3 component of complement in one. 3 patients out of 8 tested, carried the specific HLA-B8 antigen. Despite an extensive investigation, no malabsorption was detected. Jejunal biopsies were performed in 8 cases. Jejunal villous flattening was observed in one patient. It improved after a 2 months gluten free diet on subsequent jejunal biopsies. D. H. seems peculiar in France as compared with case reports from other countries: low prevalence of gluten sensitive enteropathy; rare occurrence of the specific HLA-B8 antigen; incidence of D. H. seems to be low in France. It is noticeable that french incidence of coeliac disease is low as well. This suggests a genetic difference in the investigated population (low prevalence of HLA-B8 antigen) and/or different alimentary habits, particularly a low dietary gluten amount.
