ICU Patients With ECMO And-or RRT and With Gram Negative Infections Susceptible to BL-BLIs
Conditions
Brief summary
The aim of this study is to comparatively evaluate serum concentrations of continuously applied antibiotics in ICU patients, with and without ECMO/RRT support.
Detailed description
Among all patients being treated with new generation antibiotics (beta.lactams and beta-lactamase inhibitors), we will take into consideration the results of those admitted to intensive care units. Effective antimicrobial treatment is critical to reduce their mortality associated with bacterial sepsis. They often also require extracorporeal supports, such as renal replacement therapy (RRT) and extracorporeal membrane oxygenation (ECMO), for their survival. However, few studies, limited only to some drugs, report the importance of therapeutic drug monitoring for adequate dose adjustment in these particular conditions of extracoporeal support. The risk of reaching sub therapeutic or toxic levels is quite high, due to possible very significant variations in the pharmacokinetics of the drugs because of their interaction with the various components of the ECMO and RRT devices, the characteristics of the drug itself and the pathophysiological changes of the patients on ECMO and/or RRT. Primary aim is to evaluate whether the standard prescriptions of beta lactams/beta lactamase inhibitors (BL/BLIs) are adequate to achieve the optimal PK/PD target also for ECMO and RRT (or combined) patients admitted to intensive care unit. Secondary aims include to evaluate: * the occurrence of sub-therapeutic and/or toxic drugs levels * the proportion of patients with insufficient drugs levels in different subgroups (i.e., absence of extracorporeal therapy vs. ECMO; absence of extracorporeal therapy vs. RRT, absence of extracorporeal therapy vs ECMO and RRT) - the proportion of patients with toxic or sub-therapeutic drugs levels in the same subgroups; * the proportion, when possible, of drugs level before and during the extracorporeal therapy, for the same patient; * the occurrence of drug resistance by pathogens and their mechanism
