摘要
Our aim was to investigate whether major histocompatibility complex (MHC) polymorphisms are associated with response to infliximab therapy in Japanese patients with Beh double dagger et uveitis (BU). We retrospectively reviewed 24 patients (17 men and seven women) treated with infliximab for BU. Of them, ten patients were genotyped as HLA A*2601, and nine as HLA B*5101. Therapeutic response levels in the two groups were compared based on ocular attacks and the Beh double dagger et disease ocular attack score 24 (BOS24) over 24 months of treatment. Mean frequencies of ocular attacks at 13-18 and 19-24 months after the start of treatment were significantly higher in the HLA A*2601 group (P = 0.0392 and 0.0177, respectively). Mean BOS24-6 M values for months 1-6, 7-12, 13-18, and 19-24 were also significantly higher in the HLA A*2601 group (P = 0.0459, 0.0150, 0.0394, and 0.0178, respectively). Shortening of the infusion interval was required in eight patients in the HLA A*2601 group but in one only in the HLA B*5101 group. Beh double dagger et-disease-related adverse events occurred in eight patients in the HLA A*2601 group and two in the HLA B*5101 group. Nonocular adverse events occurred in four patients in the HLA A*2601 group and none in the HLA B*5101 group. Although mean change from baseline in the number of ocular attack scores in the HLA A26 and HLA B51 groups seemed to be similar, the HLA-A26 group had a more severe disease course under infliximab therapy for ocular/extraocular involvement. These data suggest that response to infliximab therapy in Japanese patients with BU is partly due to genetic determinants in the HLA complex.
