Input: In this update, no new trials were identified (08/2002).  Only one trial with 54 men lasting 240 days (with 330 days of follow up) met study inclusion criteria. There was a statistically significant change favoring allopurinol in patient-reported discomfort between the study and control groups at follow up. Between days 45 to 225, the mean score was -0.95 (SD 0.19) for the allopurinol group (seven men), compared with -0.47 (SD 0.21) for the placebo group (seven men). The weighted mean difference (WMD) was -0.48 (95% CI -0.690 to -0.270). The mean score between days 45-135 was -1.08 (SD 1.29) for the 25 men in the allopurinol group, compared with -0.21 (SD 0.97) for the 14 men in the control group. The WMD was -0.87 (95%CI -1.587 to -0.153). The allopurinol group had significantly less investigator graded prostate pain and had lower levels of serum urate, urine urate, and expressed prostatic secretion urate and xanthine. No significant differences between the two groups regarding leukocyte counts were found. No patient receiving allopurinol had any significant side effects. Three patients in the placebo group dropped out because of side effects. One small trial of allopurinol for treating chronic prostatitis showed improvements in patient-reported symptom improvement, investigator-graded prostate pain, and biochemical parameters. However, the data provided, the measures used, and the statistics presented do not make these findings convincing that changes in urine and prostatic secretion composition regarding purine and pyrimidine bases resulted in the relief of symptoms. Further studies of allopurinol treatment using standardized and validated outcomes measures and analyses are necessary to determine whether allopurinol is effective.
Output:

Only one small randomized trial of 54 men was included in this review. Based on the results of this trial, which used non-valid ways to measure symptom improvements, allopurinol cannot be recommended. Further studies of allopurinol treatment, enrolling larger numbers of men and using standard and validated measures to measure symptom improvements, are necessary to determine whether allopurinol is an effective treatment for chronic prostatitis.
