Increased Oxidative Stress and Damage in Patients With Chronic Bacterial Prostatitis

  • Objective To investigate whether chronic bacterial prostatitis (CBP) increases oxidative stress and damage in patients with CBP, and to explore its possible mechanism. Methods Eighty patients with CBP and 80 healthy adults as controls were enrolled in a case-control study, in which levels of nitric oxide (NO), vitamin C (VC), and vitamin E (VE) in plasma, as well as malondialdehyde (MDA), activities of superoxide dismutase (SOD), and catalase (CAT) in erythrocytes were determined by spectrophotometry. Results Compared with the average values of NO, VC, VE, MDA, SOD, and CAT in the healthy control group, those of plasma NO and erythrocyte MDA in the CBP group were significantly increased (P<0.001), and those of plasma VC and YE as well as erythrocyte SOD and CAT in the CBP group were significantly decreased (P<0.001). Findings from partial correlation analysis for course of the disease and NO, VC, VE, MDA, SOD, and CAT in 80 patients with CBP, adjusted for age, suggested that with prolonged course of the disease, values of NO and MDA were gradually increased (P<0.001), and those of VC, VE, SOD, and CAT were gradually decreased (P<0.05-0.001). The findings from stepwise regression analysis for course of the disease and NO, VC, VE, MDA, SOD, and CAT in CBP group suggested that the model of stepwise regression was Y = -19.1160 +0.3112MDA + 0.0337NO, F = 22.1734, P<0.001, r = 0.6045, P<0.001. The findings from the reliability analysis for VC, VE, SOD, CAT, NO, and MDA in the CBP group showed that the reliability coefficients' alpha (6 items) was 0.7195, P<0.0001, and the standardized item alpha was 0.9307, P<0.0001. Conclusion There exist increased oxidative stress and damage induced by chronic bacterial prostatitis in patients, and such a phenomenon is closely related to the course of disease.

Abstract: Objective To investigate whether chronic bacterial prostatitis (CBP) increases oxidative stress and damage in patients with CBP, and to explore its possible mechanism. Methods Eighty patients with CBP and 80 healthy adults as controls were enrolled in a case-control study, in which levels of nitric oxide (NO), vitamin C (VC), and vitamin E (VE) in plasma, as well as malondialdehyde (MDA), activities of superoxide dismutase (SOD), and catalase (CAT) in erythrocytes were determined by spectrophotometry.
