Pharmacodynamic target attainment at infection site during treatment of post-neurosurgical ventriculitis caused by carbapenem-resistant klebsiella pneumoniae with ceftazidime-avibactam-based regimens: a case report

Int J Antimicrob Agents. 2024 Dec;64(6):107356. doi: 10.1016/j.ijantimicag.2024.107356. Epub 2024 Oct 9.

Abstract

A patient developed a post-neurosurgical ventriculitis with carbapenem-resistant Klebsiella pneumoniae and mold, initially treated with ceftazidime/avibactam and voriconazole. A Klebsiella pneumoniae carbapenemase mutation led to therapy adjustment to ceftazidime/avibactam and polymyxin B, achieving cure. Pharmacokinetic/pharmacodynamic analysis highlights effective ceftazidime/avibactam brain penetration and bacterial clearance efficacy.

Keywords: Carbapenem-resistant Klebsiella pneumoniae; Ceftazidime-avibactam; Central nervous system infection; Pharmacodynamics; Pharmacokinetics; Polymyxin B.
