NCT01659866

Brief Summary

This study is being conducted in men scheduled to undergo transrectal ultrasound-guided prostate biopsy (TRUSP). Traditionally prior to prostate biopsy, an antibiotic, ciprofloxacin, has been given to men to prevent biopsy-related infections. In recent years as ciprofloxacin resistance has increased in the community, more and more men are becoming infected with ciprofloxacin-resistant bacteria after prostate biopsy. This study is being done to determine if obtaining rectal swab cultures and choosing antibiotics based on these culture results will result in fewer infectious complications than giving all men ciprofloxacin. The investigators will compare 2 groups: men whose rectal swabs do not show ciprofloxacin-resistant bacteria will receive ciprofloxacin prior to biopsy, and men whose swabs do show ciprofloxacin-resistant bacteria will receive alternative antibiotics based on their culture results. Our hypothesis is that these 2 groups will have equal numbers of post-biopsy infectious complications and both groups will have fewer infectious complications than a historical group who received empiric ciprofloxacin without the benefit of rectal swab culture results.

Outcome Measures

Primary Outcomes (1)

  • Number of Participants With Post-biopsy Infection.

    To measure and compare the rates of infection following TRUSP in subjects with and without CR-GNB. This measure is number of participants with post-biopsy infection.

    30 days post-biopsy

Study Arms (2)

Cipro-susceptible

OTHER

Patients with ciprofloxacin-susceptible bacteria on their rectal swab cultures will receive ciprofloxacin, the standard of care, as prophylaxis for their prostate biopsy

Drug: Ciprofloxacin

Cipro-resistant

ACTIVE COMPARATOR

Patients with ciprofloxacin-resistant bacteria on their rectal swab will receive one of the following drugs: * trimethoprim-sulfamethoxazole 1 double strength tablet orally 2 hours before the procedure and again 12 hours later * cefuroxime 500 mg orally 2 hours before the procedure then again 12 hours later * ceftriaxone 500 mg intramuscularly 2 hours before the procedure * gentamicin 2mg/kg intramuscularly 2 hours before the procedure * amikacin 5 mg/kg intramuscularly 2 hours before the procedure * aztreonam 500 mg intramuscularly 2 hours before the procedure * imipenem 500 mg intramuscularly 2 hours before the procedure * ceftriaxone 2000 mg intravenously 1 hour before the procedure * gentamicin 2 mg/kg intravenously 1 hour before the procedure * amikacin 5mg/kg intravenously 1 hour before the procedure * aztreonam 2000 mg intravenously 1 hour before the procedure * imipenem 1000 mg intravenously 1 hour before the procedure

Sexmale
Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Ability and willingness to provide written informed consent.
  • All individuals who will undergo TRUSP as part of their standard of care are eligible for study.

You may not qualify if:

  • Men under 30 years of age
  • Individuals whose rectal swab indicates that they harbor CS-GNB who cannot receive ciprofloxacin as pre-procedure prophylaxis for any reason
  • Individuals whose rectal swab indicates that they harbor CR-GNB who cannot abide by the antimicrobial prophylaxis guidelines outlined in the study protocol for any reason
  • Individuals who do not wish to complete the pre-procedure risk factor questionnaire or the two post-procedure phone questionnaires to assess for infectious complications

Limitations and Caveats

Did not reach recruiting targets due to fewer prostate biopsies being performed than originally estimated in the study period.
