title: [Detection of bacterial signal of 16S rRNA gene in prostate tissues obtained by perineal approach from patient with chronic pelvic pain syndrome].
abstract: OBJECTIVE
  To explore the role of bacteria in etiology of chronic pelvic pain syndrome (CPPS), i.e., chronic prostatitis and the correlation between presence of bacterial signal of 16S ribosomal RNA (16S rRNA) gene and the response to antibiotics.
  
  
  METHODS
  Samples of prostatic and subcutaneous tissues were obtained by biopsy via perineal approach from 112 CPPS patients, aged 20 - 48. Polymerase chain reaction was conducted to detect the 16S rRNA gene of bacteria. The patients were treated with gatifloxacin 0.4 g once a day for 4 weeks and then 4 weeks later the effects of treatment were assessed by the National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI).
  
  
  RESULTS
  PCR was completed in 94 of the 112 patients, and 18 were excluded because their subcutaneous biopsies were positive for 16S rRNA, showing the possible contamination of their prostatic tissues. The total positive rate of bacterial 16S rRNA gene was 63.8% (60/94). The positive rate of bacterial 16S rRNA gene in the patients with IIIa CPPS and IIIb CPPS were 68.3% and 60.3% respectively. The total gatifloxacin effective rate of positive bacterial signal group after the was 55.0%, significantly higher than that of the negative bacterial signal group (14.7%, P < 0.001). The gatifloxacin effective rate of the 16S rRNA positive IIIa CPPS patients was 75%, significantly higher than that of the 6S rRNA negative IIIa CPPS patients (23.1%, P < 0.001), and the gatifloxacin effective rate of the 16S rRNA positive IIIb CPPS patients was 37.5%, significantly higher than that of the 6S rRNA negative IIIb CPPS patients (9.5%, P < 0.05).
  
  
  CONCLUSIONS
  Bacterial infection is related to CPPS in part of the patients. Bacterial signal detection helps predict the effect of antimicrobial therapy.
