ABSTRACT
OBJECTIVE: We designed this study to investigate the potential use of N-acetylcysteine (NAC) as an adjunct to alpha-blockers in the treatment of category III chronic prostatitis (CP).
METHODS: Sixty-three men with category III CP with a National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI) total score of 15 or more were randomized to either the NAC treatment group or the placebo treatment group. Besides tamsulosin at a dose of 0.4 mg once daily, participants based on their allocation group received NAC or placebo at a dose of 600 mg twice daily for 12 weeks. The efficacy of the medications was assessed by measuring changes in the NIH-CPSI total score and its subscales, including pain, urinary symptoms, and quality of life.
RESULTS: Based on the general linear model analysis of the data, over the 12-week treatment, NAC+tamsulosin was statistically superior to placebo+tamsulosin in reducing the total NIH-CPSI score, pain subscore, and quality-of-life subscore (P value <.001). Further, after 12 weeks, more patients in the NAC+tamsulosin group than in the placebo+tamsulosin group met the responder criterion, defined as a decrease of at least 6 points in the NIH-CPSI total score (65.6% vs 29.0%). A more favorable outcome was also noted in the NAC+tamsulosin group regarding the number of patients reporting moderate or marked improvement in symptoms (62.5% vs 25.80%). No significant difference was seen between the groups concerning changes in urinary symptoms.
CONCLUSIONS: Our study provided clinical evidence that men with category III CP might benefit from NAC treatment. Further studies are needed for the validation of these findings.
