Elevation of IgA anti-epidermal transglutaminase antibodies in dermatitis herpetiformis

Abstract

IgA antibodies to TG3 are elevated in patients with DH and adults with CD. The progressive expansion of the epitope-binding profile of IgA antitransglutaminase antibodies in patients with CD may explain the development of DH in patients with undiagnosed CD during their adult life.
