Prostatic discharge containing many septic cells is one of the typical manifestations of Reiter syndrome, a group of diseases in which fever, skin and mucous membrane damage, urethritis and conjunctivitis are the main manifestations. It’s a good idea to have a good look at the product. The following is a brief introduction: genetic and immunological theory, because the patients of this syndrome have increased blood sedimentation, C-reactive protein positive, IgG, IgA and α2 globulin increased, and non-bacterial urethritis or enteritis can occur after aseptic synovitis, suggesting that immune factors have a role in the pathogenesis. However, the presence of a generalized humoral or cellular immune abnormality as in SLE has not been confirmed, and the present arthritis may not be caused by antibodies or T cell-mediated responses. Chlamydia has recently been detected in the synovial membrane of some patients, perhaps suggesting that some bacterial component hidden in the joint is triggering the inflammation. Also, acute gonorrhea, prostatitis, chronic bacterial prostatitis, and non-bacterial prostatitis may all cause prostatic secretions containing many pus-shrinking cells.
