: The authors present the case of a critically ill morbidly obese patient (body mass index, 51.2 kg/m) who suffered from methicillin-resistant Staphylococcus epidermidis, and Candida albicans bloodstream infections. Initial treatment with caspofungin and daptomycin was deemed inappropriate, because blood cultures remained positive for both isolates after 14 days. The clinical pharmacological consultant suggested adding fluconazole and ceftobiprole to the ongoing antimicrobial therapy, and starting a real-time therapeutic drug monitoring program of daptomycin, ceftobiprole, and fluconazole, aimed at optimizing plasma exposures. Punctual minimum inhibitory concentration knowledge on the clinical isolates allowed attainment of the desired pharmacodynamic efficacy targets. Within few days, the patient greatly improved, as blood cultures became negative, and the inflammatory markers decreased to near normal values. This is a proof-of-concept of the importance of a therapeutic drug monitoring-based multidisciplinary approach in the proper management of complex antimicrobial therapy in special populations.

Abstract
: The authors present the case of a critically ill morbidly obese patient (body mass index, 51.2 kg/m) who suffered from methicillin-resistant Staphylococcus epidermidis, and Candida albicans bloodstream infections. Initial treatment with caspofungin and daptomycin was deemed inappropriate, because blood cultures remained positive for both isolates after 14 days. The clinical pharmacological consultant suggested adding fluconazole and ceftobiprole to the ongoing antimicrobial therapy, and starting a real-time therapeutic drug monitoring program of daptomycin, ceftobiprole, and fluconazole, aimed at optimizing plasma exposures. Punctual minimum inhibitory concentration knowledge on the clinical isolates allowed attainment of the desired pharmacodynamic efficacy targets. Within few days, the patient greatly improved, as blood cultures became negative, and the inflammatory markers decreased to near normal values. This is a proof-of-concept of the importance of a therapeutic drug monitoring-based multidisciplinary approach in the proper management of complex antimicrobial therapy in special populations.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
