ABSTRACT
BACKGROUND:
Recently, the spread of multidrug-resistant bacteria has become a global problem. Extended-spectrum beta-lactamase (ESBL)-producing Enterobacteriaceae (enterobacteria) is one example. The incidence of urinary tract infections caused by ESBL-producing enterobacteria has been increasing in some Japanese community settings. Currently, there is insufficient evidence on the effectiveness of oral antibiotics used for the treatment of pyelonephritis caused by ESBL-producing enterobacteria. We investigated the effectiveness of oral antibacterial agents against pyelonephritis caused by ESBL-producing Enterobacteriaceae.METHODS:
The records of patients who had been treated for pyelonephritis caused by ESBL-producing enterobacteria with oral antibiotics between April 1, 2014, and March 31, 2019, were reviewed retrospectively to assess the effectiveness of oral antibiotic treatment.RESULTS:
A total of seven cases were identified, including 1 patient with a positive blood culture and one patient with a Pitt bacteremia score of four points, indicating that the infections were severe. The antibiotics used to treat pyelonephritis were amoxicillin-clavulanic acid (n = 3), minocycline (n = 1), levofloxacin (n = 3), and sulfamethoxazole-trimethoprim with amoxicillin-clavulanic acid (n = 1). None of the patients had recurrence of pyelonephritis in the 60 days following oral antibiotic treatment, and there were no deaths during the 60-day follow-up period.CONCLUSIONS:
These antibiotics should be considered for oral treatment of pyelonephritis caused by ESBL-producing enterobacteria. However, as there is insufficient evidence available on the effectiveness of these antibiotics for the management of ESBL-producing enterobacterial infections, further large-scale prospective studies are needed.
