There are limited therapeutic options to treat infections caused by vancomycin-resistant (VREfm). The lipoglycopeptide oritavancin exhibits activity against this pathogen, although its utility against infections caused by VREfm has not been clinically established. In this study, the pharmacodynamic activity of free-drug levels associated with 12 mg/kg/day of daptomycin and a single 1,200-mg dose of oritavancin were determined against three VanA VREfm isolates in an pharmacokinetic/pharmacodynamic model.

Background: Initial antimicrobial therapy for pneumonia is frequently empirical and resistance to antimicrobial agents represents a great challenge to the treatment of patients hospitalized with pneumonia. We evaluated the frequency and antimicrobial susceptibility of Gram-negative bacteria causing pneumonia in US hospitals.
Methods: Bacterial isolates were consecutively collected (1/patient) from patients hospitalized with pneumonia and the susceptibility of Gram-negative bacilli (3,911 Enterobacterales and 2,753 non-fermenters) was evaluated by broth microdilution in a monitoring laboratory.

Background: Rates of carbapenem-resistant Acinetobacter baumannii are rising in Thailand. Although high-dose (HD) sulbactam is recommended for treating carbapenem-resistant A. baumannii infections, data on plasma sulbactam concentrations in children are limited.

Background: MDR Gram-negative bacteria, such as ESBL-producing and carbapenemase-producing Klebsiella pneumoniae, represent major global health threats. Treatment options are limited due to increasing resistance and slowed development of novel antimicrobials, making it necessary to apply effective combination therapies based on approved antibiotics.
Objectives: To quantitatively evaluate the synergistic potential of meropenem and fosfomycin against carbapenem-resistant K.

Background: Sulbactam is an effective therapy for infections. Previous sulbactam pharmacokinetics/pharmacodynamics (PK/PD) analyses established exposure efficacy targets in plasma against pneumonia. Herein, we established sulbactam efficacy targets in epithelial lining fluid (ELF).

Background: Microsampling of biological fluids followed by innovative sample pre-treatment reflects trends in bioanalytical chemistry. Volumetric absorptive microsampling (VAMS) enables exact whole blood volume collection and reduces the impact of hematocrit on the assay. In animal studies, it complies with the 3R principles (refine, reduce, replace).
