Fosfomycin in antibiotic prophylaxis of infectious complications after biopsy of the prostate

Abstract

Introduction. Biopsy of prostate is a routine urologic procedure. More than 1 million biopsies are performed worldwide annually. The frequency of infectious-inflammatory complications remain high, despite the recommended antibiotic prophylaxis schemes.Aim. The evaluation of  effectiveness and safety of  combined antimicrobial prophylaxis: Fosfomycin and Fluoroquinolones of 3rd generation.Materials and methods. 80 patients underwent prostate biopsy in our study and were divided into 2 groups: the first group of 40 patients received routine prophylaxis: Levofloxacin 500 mg 6 hours before the biopsy and 500 mg per day during 4 days after biopsy. The second group of 40 patients, along with standard prophylaxis as in the first group, additionally after biopsy received Fosfomycin 3 gr single-shot.Results and discussion. In the first group, infectious and inflammatory complications occurred in 8 patients (20%). 12.5% of patients from the first group were hospitalized for paranteral antibiotic therapy. The average length of stay in hospital was 3.4 ± 1.45 days. In all cases, in the first group of patients, E. coli was detected, in 70% of cases fluoroquinolone-resistant strain of the bacterium was received. In the second group of patients now hospitalization was required. One patient out of forty (2.5%) from this group showed signs of urinary tract infection, which was not accompanied by an increase of body temperature, as well as changes in blood and urine tests.Conclusion. Our results show good effectiveness and safety of fosfomicin for antibiotic prophylaxis for transrectal prostate biopsy.
