  • Title: Enhanced inflammatory reactivity in the pathogenesis of spondyloarthropathies.
    Author: Repo H, Ristola M, Leirisalo-Repo M.
    Journal: Autoimmunity; 1990; 7(4):245-54. PubMed ID: 2102768.
    Abstract:
    Pathogenesis of seronegative spondyloarthropathies such as ankylosing spondylitis and reactive arthritis is not known. Growing evidence indicates that microbial structures such as Chlamydia antigen and Yersinia antigen are present in the inflamed joints of patients with reactive arthritis. Microbial antigens can activate the host's inflammatory mechanisms. After the activation, the course of inflammation can be postulated to be affected by the host factors responsible for amplification of the inflammatory reaction and elimination of the foreign structures. Thus, the amplification, whether strong, moderate, or weak, may contribute to the degree of inflammatory tissue injury in patients with seronegative spondyloarthropathies. This review will discuss the role of increased inflammatory reactivity in the pathogenesis of HLA-B27 associated spondyloarthropathies, with special reference to reactive arthritis triggered by yersinia enteritis.
