Genetic predisposition is known to be an important etiopathogenic factor of autoimmune hepatitis (AIH). HLA antigens associated with AIH have been well studied in Western countries and Japan, but there is no HLA typing data of AIH patients in Taiwan. We therefore investigated HLA phenotypes and their association with AIH patients and compared the results with those of normal subjects and patients with chronic liver disease. Group 1 consisted of 22 AIH patients. All were born in Taiwan with no history of blood transfusion. Group 2 consisted of 19 chronic liver disease patients. Group 3 consisted of 81 unrelated healthy subjects who were normal blood donors. All three groups were tested for HLA phenotypes (HLAA, B, C, DR, DQ) using the polymerase chain reaction-sequence specific probe method. The statistical method used was Fisher's exact test. We found that HLA-DQ5 was significantly more frequent in the AIH group compared to the control group (RR, 2.03; p = 0.034). Low frequency of A1 (n = 2/22), B8 (n = 1/22) and DR3 (n = 0/22) were noted compared to results from the West; only HLA-DR4 showed a higher rate in our AIH patients (n = 8/22). This is a preliminary report of our study of HLA antigens in AIH patients. Further investigation to characterize AIH patients into HLA allelic subgroups is being done.
