    Infectious arthropathies

    • This block comprises arthropathies due to microbiological agents. Distinction is made between the following types of etiological relationship:
    • a) direct infection of joint, where organisms invade synovial tissue and microbial antigen is present in the joint;
    • b) indirect infection, which may be of two types: a reactive arthropathy, where microbial infection of the body is established but neither organisms nor antigens can be identified in the joint, and a postinfective arthropathy, where microbial antigen is present but recovery of an organism is inconstant and evidence of local multiplication is lacking.

    Postinfective and reactive arthropathies
Clinical Information
  • An aseptic, inflammatory arthritis developing secondary to a primary extra-articular infection, most typically of the gastrointestinal tract or urogenital system. The initiating trigger pathogens are usually shigella; salmonella; yersinia; campylobacter; or chlamydia trachomatis. Reactive arthritis is strongly associated with hla-b27 antigen.
  • Historically characterized by a triad of inflammation involving the eye (conjunctivitis), the bone (post-infectious arthritis), and the urethra (urethritis), it is now thought to be nearly synonymous with reactive arthritis.
  • Triad of nongonococcal urethritis followed by conjunctivitis and arthritis.
