  • Title: Antigliadin and antireticulin antibodies in children with dermatitis herpetiformis.
    Author: Vainio E, Kosnai I, Hällström O, Karpati S, Mäki M, Reunala T.
    Journal: J Pediatr Gastroenterol Nutr; 1986; 5(5):735-9. PubMed ID: 3531458.
    Abstract:
    The serum samples of 27 children with dermatitis herpetiformis (DH) were examined for the presence of antigliadin (AGA) and antireticulin (ARA) antibodies. AGA were determined with an enzyme-linked immunosorbent assay (ELISA) and ARA with an immunofluorescence method. Increased IgA or IgG class AGA levels were found in four of ten children on a normal diet, in two of 25 on a gluten-free diet (GFD), and in two of four children on gluten challenge. The corresponding figures for ARA were nine of ten, two of 25, and four of four, respectively. All nine patients with ARA on a normal diet had either subtotal or partial villous atrophy, whereas the patient negative for ARA had a normal jejunal mucosa. ARA were mostly of IgA class, and after gluten withdrawal, increased levels fell to normal range. Four children were challenged with gluten, and they all developed subtotal villous atrophy and demonstrated IgA class ARA. These results suggest that in childhood DH, ARA is a more sensitive indicator of gluten-sensitive enteropathy than AGA, but both antibody determinations can be used in monitoring adherence to GFD treatment.
