"[The following observations were made: (1) the intestinal biopsies revealed a direct correlation between degree of lesions and age at onset of DH; (2) a significantly increased relative risk (RR) was found for the following HLA antigens: A1 (RR = 2.2), B8 (RR = 6.2), Cw7 (RR = 3.9), C4AQ0 (RR = 7.4), DR3 (RR = 5.2), DR7 (RR = 4.4), DRw53 (RR = 4.7), DQw2 (RR = 6.0); (3) B8 and DR3 were significantly more frequent in patients with severe intestinal lesions; and (4) of the two DR3 subtypes revealed by RFLP typing, only 3.1 showed an increased frequency in DH patients (RR = 8.4).].
