title: Relation between HLA-B27 and clinical features in patients with yersinia arthritis.
abstract: A study of 74 yersinia arthritis patients implied that the clinical picture of the disease may be modified by genetic background associated with the histocompatibility antigen B27 (HLA-B27). Sixty-six percent of patients were B27 positive. Joint symptoms were somewhat more severe in B27+ patients. Iritis, conjunctivitis, carditis, signs of urologic inflammation, and complete Reiter's triad occurred only in the B27 + group, whereas erythema nodosum was more common in B27 - group. Several B27 + patients also had "B27 + rheumatic diseases," such as ankylosing spondylitis or Reiter's disease, in their history.
