title: Reiter's syndrome associated with HLA-B51: a case report.
abstract: A 32-year-old Japanese man developed polyarthritis with mild fever and conjunctivitis. Clinical assessment indicated non-specific arthritis, aseptic pyuria induced by infection with Chlamydia, and conjunctivitis. He was diagnosed with reactive arthritis (Reiter's syndrome). Serotyping of human leucocyte antigen (HLA) class I and II revealed positivity for B51(5), A2, A33(19), B44(12), Cw1, DR4 and DR6, but B27 was negative. He was treated with a combination of doxycycline, oral prednisolone, diclofenac sodium and salazosulphapyridine. Fever and arthralgia improved and he became negative for anti-Chlamydia immunoglobulin (Ig) A and IgG antibodies. HLA-B51 may be involved in the pathogenesis of Reiter's syndrome in this Japanese patient.
