Clinical Cure of a Difficult-to-Treat Resistant Pseudomonas aeruginosa Ventriculitis Using Cefiderocol: A Case Report and Literature Review

Ventriculitis is a complication of meningitis (community-acquired or nosocomial) or other central nervous system (CNS) infections such as brain abscess. They are associated with a different spectrum of microorganisms, from resistant gram-negative bacilli to staphylococci, that can lead serious illness with high mortality. Difficult-to-treat resistance (DTR) gram-negative bacilli may increase to 20% of deaths respective to susceptible isolates of the same bacteria. We present the first report of a clinical cured case of DTR Pseudomonas aeruginosa ventriculitis in which cefiderocol penetration into the CNS has been confirmed in blood and cerebrospinal fluid. Cefiderocol might be considered for difficult-to-treat CNS infections in view of the recent new cases published as well as our case.
