Summary

Chronic abacterial prostatitis shows immune system involvement, with specific antibodies and complement factors detected in patient tissues. These immune deposits correlate with key prostatitis symptoms, suggesting a potential immunological basis for the condition.

Area of Science:

  • Urology
  • Immunology
  • Pathology

Background:

  • Chronic abacterial prostatitis (CAP) is a common urological condition with unclear etiology.
  • Understanding the underlying mechanisms of CAP is crucial for developing effective treatments.

Purpose of the Study:

  • To investigate the presence and patterns of immune deposition in prostatic tissues of patients with CAP.
  • To explore the correlation between immune markers and clinical symptoms in CAP.

Main Methods:

  • Direct immunofluorescence (IF) technique was used to examine prostatic biopsies from 60 CAP patients and 21 controls.
  • Antibody (IgM, IgA, IgG), complement (C3), and fibrinogen deposition were assessed.

Main Results:

  • 57% of CAP patients showed IF staining in prostatic tissue, compared to 5% in controls.

  • IgM, C3, IgA, and fibrinogen deposition were frequently observed in CAP patients.
  • Specific symptoms like poor urinary flow, irritative voiding, and urgency correlated significantly with IgM, C3, and fibrinogen deposition.

    • Conclusions:

    • Immune system activation, evidenced by antibody and complement deposition, is implicated in the pathophysiology of CAP.
    • The correlation between immune deposits and symptoms suggests an immunological component contributing to CAP symptomatology.
    • Potential mechanisms involve intraprostatic urine reflux inciting an immune response.
