Purpose: Epidemiological evidences had shown that patients with Helicobacter pylori (H.p.) infection had more urological prostatitic diseases. And chronic prostatitis patients had significantly higher positive anti-H.p. rate. Therefore, we investigated the possible role of H.p. in chronic prostatitis.
Materials and Methods: We set up chronic prostatitis model by introducing H.p. into male rats. Physiological bladder changes along with pain sensitivity in scrotum and tail base were evaluated with cystometrogram and Von Frey filament correspondently. Local prostatic inflammation was checked with Western blot and immunohistochemical stain. Systemic inflammation was evaluated by checking cytokines in spleen. .
Results: Hypersensitivity in rat scrotum confirmed the development of chronic prostatitis. Tail base sensitivity showed less significant correspondence. There was significant difference caspase 1 expression in H.p. antigen stimulated prostate. Matured caspase 1 ratio also increased. However, local IL-1b did not seem to have significance. Systemic inflammation was confirmed by significantly increased TNF-alpha in spleen protein extraction.
Conclusions: H.p. antigen may induce local and systemic inflammation. Local effect in prostate induces chronic prostatitis-like response. Further investigation on the systemic effect of H.p. antigen may be necessary to confirm its immunological role on chronic prostatitis.
