OBJECTIVES: EUCAST recently advised against temocillin use, except for non-serious urinary tract infections (UTI) caused by Escherichia coli, Klebsiella spp. (except Klebsiella aerogenes) and Proteus mirabilis (EKP) treated with a dose of 2 g q8h. We aimed to analyse our practice in the context of a larger temocillin use in France.
PATIENTS AND METHODS: All ≥3 day temocillin prescriptions from 2016 to 2019 were reviewed, with reference to French recommendations and a susceptibility breakpoint of 8 mg/L. The primary outcome was early clinical failure (antibiotic switch, relapse or death within 10 days after the completion of antibiotic treatment).
RESULTS: Overall, 153 cases were analysed: 123 cases of UTI (80.4%) and 133 cases of monomicrobial infection with Enterobacterales (86.9%). A total of 160 Enterobacterales were isolated, comprising 108 (67.5%) ESBL producers and 30 (20.7%) non-EKP species. The rate of early clinical failure was 9.2% and was significantly lower for UTI compared with non-UTI (4.9% versus 26.7%, P = 0.001) and for sepsis compared with severe sepsis or septic shock (6.2% versus 25%, P = 0.011). It was not different between 2 g q12h and 2 g q8h doses (10% versus 7.4%, P = 0.81) and between EKP and other Enterobacterales (8.7% versus 14.3%, P = 0.41).
CONCLUSIONS: EUCAST recommendations on urinary isolates seem to be too restrictive. Our data support the efficacy of temocillin at a dose of 2 g q12h to treat patients with non-severe complicated UTI caused by MDR Enterobacterales with an MIC of ≤8 mg/L, whatever the species.
