Sitafloxacin and Ertapenem Treatment for Acute Pyelonephritis Caused by Escherichia Coli
Sitafloxacin and Ertapenem Treatment for Acute Pyelonephritis Caused by Escherichia Coli
The aim of the investigators' study was to evaluate oral and non carbapenem antimicrobial
 agents which can be used in outpatient for the treatment of non-bacteremic acute
 pyelonephritis caused by Extended Spectrum Beta Lactamase Escherichia coli. This study was
 conducted to compare the clinical and bacteriological outcomes of patients with
 non-bacteremic acute pyelonephritis caused by Extended Spectrum Beta Lactamase Escherichia
 coli who were treated with intravenous (IV) carbapenems followed by oral sitafloxacin or IV
 ertapenem.
A prospective randomized controlled trial of patients with a presumptive diagnosis of acute
 pyelonephritis caused by Extended Spectrum Beta Lactamase-producing pathogen was performed.
 Carbapenems was initially given to all patients. After day 3, patients were randomized to
 receive either oral sitafloxacin (100 mg twice daily) or intravenous ertapenem. The regular
 course of treatment was completed within 10 days.
