Epidemiology and O-Serotypes of Extraintestinal Pathogenic Escherichia Coli Disease in Patients Undergoing Transrectal Ultrasound Prostate Biopsy: A Prospective Multicenter Study.
The Journal of urology/The journal of urology(2021)
摘要
PURPOSE Extraintestinal pathogenic Escherichia coli (ExPEC) are a leading cause of invasive infections in adults. The study aimed to evaluate the incidence of microbiologically confirmed Invasive ExPEC disease (IED) in patients undergoing transrectal ultrasound-guided prostate needle biopsy (TRUS-PNB), O-serotype distribution and antibiotic resistance profiles of associated E. coli isolates. MATERIALS AND METHODS Adult men (≥18 years) undergoing TRUS-PNB were enrolled. The TRUS-PNB procedure was performed according to local standard of care, including preferences of prophylactic antibiotics. Clinical and microbiological data were collected. RESULTS Of the 4951 patients (mean age: 66.9 years) enrolled, 4935 (99.7%) underwent TRUS-PNB (95.1% received prophylactic antibiotics); 98.9% completed the study. Overall incidence of IED was 0.67% (33/4935 patients; 95% CI: 0.46-0.94); highest incidence was in US (0.97%, 14/1446 95% CI: 0.53-1.62). Prevalence of the 10 selected O-serotypes O1, O2, O4, O6, O8, O15, O16, O18, O25, and O75 was 52.0% (95% CI: 31.3-72.2). E. coli isolates showed highest resistance rates to levofloxacin and ciprofloxacin (76%; 95% CI: 54.8-90.6 for both). Among fluoroquinolone-resistant ExPEC isolates, prevalence of the 10 selected O-serotypes was 60%. CONCLUSIONS This study provides an estimate of microbiologically confirmed IED incidence following TRUS-PNB. Information on E. coli O-serotype distribution and associated antibiotic resistance profiles from IED cases in the first 30 days following TRUS-PNB may help guiding antibiotic use and inform development of a prophylactic ExPEC vaccine.
