OBJECTIVE: To evaluate the real-world clinical efficacy of ceftolozane/tazobactam (C/T) in difficult-to-treat infections caused by multi-drug resistant Gram-negative microorganisms, including carbapenem-resistant Pseudomonas aeruginosa.
METHODS: Retrospective cohort study of adult patients treated with C/T for at least 48 hours for infections caused by multi-drug resistant Gram-negative bacteria in a tertiary hospital from May 2016 until August 2019. The primary outcome analysed was clinical failure, defined as a composite of symptomatology persistence after 7 days of C/T treatment, infection recurrence, and/or all-cause mortality within 30 days of follow-up.
RESULTS AND DISCUSSION: 96 episodes of C/T treatment were included, mostly consisting of targeted treatments (83.9%) for the following sources of infection: intra-abdominal (22.6%), urinary tract (25.8%), skin and soft tissue (19.4%), hospital-acquired pneumonia (14%), and other (6.4%). The most frequently isolated bacteria were carbapenem-resistant (88, 94.6%). Clinical failure rate was 30.1%, due to persistent infection at day 7 (4.3%), recurrence of the initial infection (16.1%), or 30-day all-cause mortality (8.6%). Adverse events most frequently reported were Clostridium difficile infection (9%) and cholestasis (8%).
WHAT IS NEW AND CONCLUSION: C/T showed a favourable clinical profile for difficult-to-treat multidrug-resistant and carbapenem-resistant Gram-negative infections, regardless of the source of infection.
