A study was undertaken to determine whether the skin eruption of linear IgA disease (LAD) was gluten dependent. Six patients with LAD were treated with a gluten free diet (GFD) for an average period of 33 months (range 19-48). Although one patient with LAD had an enteropathy which was clearly gluten sensitive, there was no convincing evidence that the rash of any of the patients responded to a GFD. Four of the six patients showed no significant alteration in their drug requirements. The remaining 2 patients showed a fall in minimum drug requirement but there was no increase after gluten challenge indicating that they were entering spontaneous remission. This contrasts to the situation in dermatitis herpetiformis, where both the rash and the enteropathy are gluten dependent. These data add further to the evidence that LAD and dermatitis herpetiformis are separate entities.
