ABSTRACT
Drug-induced interstitial lung disease (DILD) is a life-threatening adverse reaction. The Japanese population is more susceptible to DILD as compared with other populations, suggesting its pathogenesis could vary depending on ethnic genetic background. We conducted case-control studies to elucidate the association between DILD and HLA alleles in the Japanese. The 177 clinically diagnosed DILD patients and 3002 healthy controls for exploration and 55 DILD patients and 201 healthy controls for validation were genotyped for four HLA genes. HLA-DRB1*0405 was significantly associated with DILD (corrected p = 0.014); this was also validated in the other set of patients/controls. Chemical drugs other than protein therapeutics showed this association (p = 1.7 × 10-4) . The Japanese population showed a higher HLA-DRB1*0405 frequency than most other populations. In conclusion, HLA-DRB1*0405 could be associated with DILD susceptibility in Japanese individuals, and its high general frequency may explain the high reported incidence of DILD in Japanese.
