An in vitro single-compartment dilutional pharmacokinetic model was used to study the pharmacodynamics of ceftaroline against Staphylococcus aureus (both methicillin-susceptible S. aureus [MSSA] and methicillin-resistant S. aureus [MRSA]). Mean serum free concentrations of ceftaroline (the active metabolite of the prodrug ceftaroline fosamil) dosed in humans at 600 mg every 12 h (q12h) were sim...
BACKGROUND Ertapenem is a novel carbapenem with activity against both penicillin-susceptible (MIC < or = 0.06 mg/L) and penicillin-non-susceptible (MIC > or = 0.12 mg/L) Streptococcus pneumoniae. This study assessed the pharmacodynamic activity of ertapenem against penicillin-susceptible and penicillin-non-susceptible S. pneumoniae using an in vitro pharmacodynamic model. METHODS Fifteen S. p...
BACKGROUND Ectopic pregnancy (EP) occurs in 1-2% of pregnancies, but is over-represented as a leading cause of maternal death in early pregnancy. It remains a challenge to diagnose early and accurately. Women often present in early pregnancy with a 'pregnancy of unknown location' (PUL) and the diagnosis and exclusion of EP is difficult due to a lack of reliable biomarkers. A serum biomarker abl...
In vivo pharmacodynamic parameters have been characterized for a variety of antibacterial agents. These parameters have been studied in correlation with in vivo outcomes in order to determine (i) which dosing parameter is predictive of outcome and (ii) the magnitude of that parameter associated with efficacy. Very little is known of the pharmacodynamics of antifungal agents. We used a neutropen...
As natural products garner attention in the medical field, the emergence of antibiotic-resistant strains of bacteria has confounded the current use of antibiotic therapy, leading to the re-examination of earlier remedies such as honey and royal jelly (RJ). Four varieties of honey and one variety of freshly reaped RJ were used to evaluate the additive antimicrobial action against Pseudomonas aer...
BACKGROUND Vancomycin hydrochloride treatment failure for infections caused by susceptible methicillin-resistant Staphylococcus aureus (MRSA) strains with high minimum inhibitory concentration (MIC) has prompted recent guidelines to recommend a higher vancomycin target trough of 15 to 20 microg/mL. METHODS A prospective cohort study of adult patients infected with MRSA was performed to determ...
Coagulase negative staphylococcal sepsis in neonates: do we need to adapt vancomycin dose or target?
BACKGROUND Despite differences in types of infection and causative organisms, pharmacokinetic-pharmacodynamic (PKPD) targets of vancomycin therapy derived from adult studies are suggested for neonates. We aimed to identify doses needed for the attainment of AUC/MIC > 400 and AUC/MIC > 300 in neonates with sepsis and correlate these targets with recommended doses and treatment outcome. METHODS...
Staphylococcus pseudintermedius is a coagulase-positive species that colonizes the nares and anal mucosa of healthy dogs and cats. Human infections with S. pseudintermedius range in severity from bite wounds and rhinosinusitis to endocarditis; historically, these infections were thought to be uncommon, but new laboratory methods suggest that their true incidence is underreported. Oxacillin and ...
BACKGROUND Elevated macrophage inhibitory cytokine-1 (MIC-1/GDF15) levels in serum mediate anorexia and weight loss in some cancer patients and similarly elevated levels occur in chronic kidney disease (CKD). Serum MIC-1/GDF15 is also elevated in chronic inflammatory diseases and predicts atherosclerotic events independently of traditional risk factors. The relationship between chronic inflamma...
OBJECTIVES Although most susceptibility studies for linezolid have investigated aerobic bacteria, only a few have investigated anaerobe isolates. The aim of the present study was to determine the antibacterial activity of linezolid against a larger sample of clinical isolates of Fusobacterium spp. and to report on the detailed susceptibility, stratified by species. METHODS The in vitro suscep...
