A single dose of meropenem is superior to ciprofloxacin in preventing infections after transrectal ultrasound-guided prostate biopsies in the era of quinolone resistance
Abstract
PURPOSE: To evaluate the efficacy of meropenem single dose before transrectal prostate biopsy, instead of ciprofloxacin in the era of fluoroquinolones resistance.
METHODS: This prospective study included patients with indications for prostatic biopsy from January to December 2014. Those with known resistance in fluoroquinolones or meropenem or with decreased creatinine clearance were excluded. Patients were randomized into two groups, and statistical analysis was carried out. Group A received a 3-day course of ciprofloxacin 500 bid per os starting the day before biopsy. Group B received 1 g meropenem intravenously 1 h prior to the procedure. Patients were followed up for 15 days, and those with lower urinary tract symptoms (LUTS) and fever were called for hospitalization. Urine and blood cultures were obtained.
RESULTS: A total of 110 patients, 52-75 years old (mean 67.5, median 66) participated in the study, allocated in Groups A and B. After the procedure, 18 patients (32.7 %) of Group A reported macroscopic hematuria, while 10 (18.2 %) reported rectal blood loss. Nine patients (16.3 %) presented because of fever and LUTS. One of them developed septic shock and died in the ICU. Cultures revealed multi-resistant E. coli with high sensitivity to meropenem, and patients were treated accordingly. In Group B, 20 (36.3 %) patients presented with macroscopic hematuria and 9 (16.3 %) with rectal blood loss. One patient returned to hospital with LUTS and fever. Cultures revealed…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 110 participants or records.
