PG - 91-7 AB - We carried out human leukocyte antigen (HLA)-A, B, Cw, DR and DQ serological typing and HLA-DQA1, DQB1, DRB1 and DPB1 genetic typing for 46 Japanese haemophilia A patients, including 20 who had developed an antibody to factor VIII. It appears that anti FVIII inhibitor formation is associated with the major histocompatibility complex in Japanese haemophilia A patients. Absence of HLA-A24 is a principal risk factor for inhibitor formation in Japanese haemophilia A patients. As supplemental risk factors, HLA-DR4.1, DQ4 and DQA1*0301=2 are positively associated with patients exhibiting inhibitor compared with normal subjects. This and previous studies show that the association between HLA antigens and the formation of inhibitor depends on race. Data of HLA typing may be useful for the recognition of groups at high risk for the possible formation of inhibitor among Japanese haemophilia A patients.
