[HLA antigens in stomach ulcer]

A total of 55 gastric ulcer patients and 1045 healthy persons were investigated for 36 HLA antigens (A, B, C loci). The study revealed that HLA B12, B15, B35, Cw4 were more common in the patients (34.55, 18.18, 27.27 and 25.45%, respectively). HLA A3 (10.9% in the patients and 25.74% in those healthy) is found to be protective against gastric ulcer. The data obtained are considered with regard to heterogeneity of the disease.
