Abstrakt: In the last decades, the worldwide spread of difficult-to-treat (DTR) Gram-negative bacteria has prompted the use of newly approved antimicrobials with activity against MDR microorganisms, in particular carbapenem-resistant strains.[1] Bacterial meningitis is I per se i a severe infection, especially in the paediatric population and if MDR bacteria are involved.[2] We here describe the case of an infant successfully treated with cefiderocol for meningoencephalitis caused by DTR I Pseudomonas aeruginosa i . The patient completed 8 weeks of treatment with cefiderocol uneventfully with progressive improvement in MRI images and subsequent negative CSF culture results. CSF penetration of cefiderocol was 69.5%, higher than previously reported in adults,[10] probably due to the severity of the patient's clinical condition with a consequent high blood-brain barrier permeability.
