摘要:

Immunological studies of prostatitis have developed from findings of antibody coated bacteria in the 1970s to the more recent studies of various models of autoimmunity. This review presents data suggesting that possible causes for prostatitis (bacterial or otherwise) may be explained under an immunological umbrella.

摘要:

Chronic idiopathic prostatitis, sometimes called prostatodynia or abacterial prostatitis, is a commonly diagnosed and poorly treated urological syndrome. Clinically, this condition frustrates the patient and physician due to its chronicity and resistance to therapy. Recent studies suggest that the etiology of chronic idiopathic prostatitis may be of bacterial origin. Three types of provocative data have demonstrated bacterial presence from prostatic specimens (tissue and secretions) that were negative by traditional clinical microbiologic tests: (i) presence of bacterial gene sequences in prostatic tissue encoding 16S rRNA and tetracycline resistance (tetM‐tetO‐tetS); (ii) controlled cultural findings showing coagulase‐negative staphylococci as the most common isolates (68%) in prostatodynia (chronic idiopathic prostatitis); and (iii) culture of difficult‐to‐grow coryneforms in expressed prostatic secretions (EPS) on enriched culture media and direct microscopic observation of these pleomorphic bacteria in EPS. Additionally, earlier experimental studies in a rat model support the concept that antibiotic therapy in chronic bacterial prostatitis may not be due to altered antibiotic pharmacokinetics in the chronically inflamed prostate gland. Rather, ineffective antimicrobial eradication might result from protected bacterial micro‐colonies within an infection‐induced altered micro‐environment deep within the prostate gland. We postulate that extracellular slime substances produced by bacteria that are buried in prostatic tissues could impair host defenses by their anti‐phagocytic and anti‐chemotactic properties that affect neutrophils as well as anti‐proliferative characteristics that affect lymphocytes. These extracellular slime substances could also have cytoprotective properties which can conceal bacteria from otherwise bactericidal levels of antibiotics and lead to recrudescent infections resistant to therapy. Persistence of bacterial antigens might initiate a cascade of cellular immunologic events resulting in chronic inflammation of the prostate gland.

摘要:

Assessment of men suffering from proven chronic prostatitis involves a cascade of diagnostic steps, including evaluation of symptoms and clinical features, objectivation of the inflammatory response in expressed prostatic secretions, standardized localization techniques for common bacteria and a search for fastidious, uncommon pathogens.

摘要:

The therapeutics of chronic prostatitis remain as enigmatic as the disease. In light of the recent guidelines from the National Institutes of Health, there may finally be satisfactory evaluation of efficacy.
