Author Information

An event is serious (based on the ICH definition) when the patient outcome is:

  • * death

  • * life-threatening

  • * hospitalisation

  • * disability

  • * congenital anomaly

  • * other medically important event

In a prospective observational study of 58 patients performed between May 2016 and September 2017, eight patients [ages and sexes not stated] were described, who developed resistance to ceftolozane/tazobactam during treatment of multidrug resistant Pseudomonas aeruginosa infection [routes, duration of treatments to reactions onset and outcomes not stated; not all doses stated].

Patient 1: A patient, who had multidrug resistant Pseudomonas aeruginosainfection, received treatment with ceftolozane/tazobactam along with meropenem, ceftazidime and amikacin. The dose of ceftolozane in ceftolozane/tazobactam was reported as 1g. A sample bronchial aspirate isolated on 18 Jul 2016 showed minimum inhibitory concentration (MIC) of ceftolozane/tazobactam 4 mg/L and on 31 Jul 2016 MIC of...
