ABSTRACT
HLA association with drug-induced liver injury has recently been pointed out about multiple medicines. The aim of this study was to evaluate relationship between HLA gene and liver injury related to Baikal skullcap-containing Kampo medicines (BSCK). We previously examined HLA genes in 3 cases of BSCK-induced liver injury. Recently we could encounter 2 cases diagnosed as "definitely-related case" of BSCK-induced liver injury. HLA genes of the 2 cases were analyzed by Sequencing Based Typing method with Next Generation Sequencer at HLA Laboratory in Kyoto. HLA-DPA1*020202 and DPB1*050101 were observed in the 2 cases concordance was not observed in HLA-A, B, C, DRB1, DRB4, DQA1, or DQB1. The previous 3 cases of BSCK-induced liver injury had the same allele type to the 2 cases only in HLA-DPA1. Putting all these together, HLA-DPA1*020202 was observed in common among 5 cases of BSCK-induced liver injury. HLA-DPA1*020202 is possibly associated with BSCK-induced liver injury.
