We have noted increased oxidative stress in the prostatic fluid of these patients, implying an active inflammatory response. Immune cells can produce the natural opioid β-endorphin at the site of injury, which may modulate pain. We measured β-endorphin and the inflammatory marker prostaglandin E2 in the expressed prostatic secretions of men with prostatitis, and correlated the results with symptoms. Materials and Methods: Expressed prostatic secretions samples from 70 patients and 8 asymptomatic controls were collected and frozen. β-Endorphin and prostaglandin E2 were measured by enzyme-linked immunosorbent assay. Results were stratified according to prostatitis category and compared in individuals before and after therapy. Results: In symptomatic patients β-endorphin and prostaglandin E2 were not significantly different in categories II, IIIa and IIIb expressed prostatic secretions but they were higher than in controls. The mean β-endorphin level plus or minus standard error of mean in symptomatic patients was significantly higher (23.8 ± 11 ng./ml. versus 8.7 ± 4.7, p = 0.0001) and mean prostaglandin E2 was lower (6.01 ± 2.9 ng./ml. versus 3.01 ± 2.9, p = 0.001) after successful therapy with antibiotics or antioxidant phytotherapy, Prosta-Q (Farr Laboratories, Santa Clarita, California). Conclusions: We observed a correlation of higher prostaglandin E2 and lower β-endorphin in symptomatic men with chronic prostatitis. Increased oxidative stress and inflammation may induce prostaglandin E2 production that would inhibit β-endorphin release. Treatment with therapeutic agents that decrease oxidative stress, such as antibiotics and antioxidant phytotherapy, may function at least partially by increasing β-endorphin and decreasing prostaglandin E2.
