Autoimmune etiology in chronic prostatitis syndrome: an advance in the understanding of this pathology.
The prostate is the target of many inflammatory and neoplastic disorders that affect men of all ages. Pathological conditions of the prostate gland range from infection of this organ by ascending bacteria from infected urine, to chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) of a still unknown etiology (accompanied with inflammation and lymphocyte infiltration of the gland), to benign hyperplasia and cancer. Patients under 50 years of age usually suffer from CP/CPPS, a chronic inflammatory syndrome characterized by pelvic pain, irritative voiding symptoms, and sexual dysfunction complaints. In this review, we summarize the current knowledge regarding immunological alterations present in CP/ CPPS patients. Remarkably, an inflammation state, in the absence of an invading infectious agent, is established in these patients, suggesting that an autoimmune process could be involved. In fact, specific autoimmune response to prostate antigens has recently been reported in CP/CPPS patients. Autoimmune response to prostate gland affects the seminal quality reported in these patients and may have critical consequences in their fertility. It is anticipated that preclinical studies in experimental models for CP/CPSS will provide important insights into the etiopathogenic mechanisms involved in this disease. We discuss here the similarities and the differences between human disease and experimental models and argue for the importance of the prostate gland in male reproductive function. Ultimately, we suggest that a state of inflammation, originally incited by an autoimmune response within the prostate, together with a diminished prostate functionality, may compromise male fertility.
