Combination antibiotic therapy for treatment of a patient with infected prosthesis and peri-prosthetic abscess due to Klebsiella pneumoniae harboring New Delhi Metallo (NDM) beta-lactamase.
Overview
abstract
Treatment options for patients infected with multi-drug resistant gram-negative bacteria harboring metallo-beta-lactamases (MBLs) requires precision therapy. We present the case of a 20 year-old male with a right distal femoral peri-prosthetic abscess with presumed infected hardware and osteomyelitis in whom four multi-drug resistant gram negative bacteria were isolated. The rapid identification of an MBL producing organism, novel combination of therapy, and prompt infection prevention enforcement and education led to appropriate treatment of our patient as well as prevention of spread of organisms during and after hospitalization. This case illustrated successful management of multiple challenges faced by patients infected and/or harboring extensively resistant bacteria.
