OBJECTIVE To summarize the pharmacokinetic and pharmacodynamic properties of ticagrelor, a selective P2Y12 receptor antagonist, and evaluate its role in the treatment of patients with acute coronary syndromes (ACS). DATA SOURCES A literature search was conducted in MEDLINE (1966-November 2009), International Pharmaceutical Abstracts (1970-November 2009),(More)
Enterococcus species are the second most common cause of nosocomial infections in the United States and are particularly concerning in critically ill patients with preexisting comorbid conditions. Rising resistance to antimicrobials that were historically used as front-line agents for treatment of enterococcal infections, such as ampicillin, vancomycin, and(More)
Ceftolozane-tazobactam (TOL-TAZ) is a novel cephalosporin/beta-lactamase inhibitor with activity against several Gram-negative pathogens. Daptomycin (DAP) has demonstrated synergistic activity with beta-lactams against methicillin-resistant Staphylococcus aureus (MRSA) isolates with reduced lipopeptide and glycopeptide susceptibilities. Our objective was to(More)
Oritavancin possesses activity against vancomycin-resistant enterococci (VRE) and methicillin-resistantStaphylococcus aureus(MRSA).In vitrodata suggest synergy between beta-lactams (BLs) and vancomycin or daptomycin, agents similar to oritavancin. We evaluated the activities of BLs combined with oritavancin against MRSA and VRE. Oritavancin MICs were(More)
Daptomycin (DAP) is being used more frequently to treat infections caused by vancomycin-resistant enterococcus (VRE). DAP tends to be less active against enterococci than staphylococci and may require high doses or combination therapy to be bactericidal. Fosfomycin (FOF) has activity against VRE and has demonstrated synergistic bactericidal activity with(More)
Ertapenem and cefazolin were used in combination to successfully clear refractory methicillin-susceptible Staphylococcus aureus (MSSA) bacteremia. In addition, recent work has demonstrated activity of combination therapy with beta-lactams from different classes against methicillin-resistant S. aureus (MRSA). The ertapenem-plus-cefazolin combination was(More)
In this study, we describe the genetic features of an XDR KPC-2-producing Klebsiella pneumoniae isolate by using whole-genome sequencing, its clinical-epidemiological context and susceptibility against antimicrobial combinations. The isolate belongs to clonal complex 258 and harbors several acquired genes and mutations associated with antimicrobial(More)
Ceftaroline is a novel cephalosporin recently approved in children for treatment of acute bacterial skin and soft tissue infections and community-acquired bacterial pneumonia (CABP) caused by methicillin-resistant Staphylococcus aureus, Streptococcus pneumoniae and other susceptible bacteria. With a favorable tolerability profile and efficacy proven in(More)
Objectives Among viridans group streptococcal infective endocarditis (IE), the Streptococcus mitis group is the most common aetiological organism. Treatment of IE caused by the S. mitis group is challenging due to the high frequency of β-lactam resistance, drug allergy and intolerability of mainstay antimicrobial agents such as vancomycin or gentamicin.(More)
The evidence for using combination therapy for the treatment of serious methicillin-resistant Staphylococcus aureus (MRSA) infections is growing. In this study, we investigated the synergistic effect of daptomycin (DAP) combined with piperacillin-tazobactam and ampicillin-sulbactam against MRSA in time-kill experiments. Six of eight strains demonstrated(More)
