    Gram-positive bacterial infections: research priorities, accomplishments, and future directions of the antibacterial resistance leadership group
    (Oxford University Press, 2017) Doernberg, Sarah; Lodise, Thomas; Thaden, Joshua; Munita, José; Cosgrove, Sara; Arias, Cesar; Boucher, Helen; Corey, G. Ralph; Lowy, Franklin; Murray, Barbara; Miller, Loren; Holland, Thomas
    Antimicrobial resistance in gram-positive bacteria remains a challenge in infectious diseases. The mission of the Gram-Positive Committee of the Antibacterial Resistance Leadership Group (ARLG) is to advance knowledge in the prevention, management, and treatment of these challenging infections to improve patient outcomes. Our committee has prioritized projects involving methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant enterococci (VRE) due to the scope of the medical threat posed by these pathogens. Approved ARLG projects involving gram-positive pathogens include (1) a pharmacokinetics/pharmacodynamics study to evaluate the impact of vancomycin dosing on patient outcome in MRSA bloodstream infection (BSI); (2) defining, testing, and validating innovative assessments of patient outcomes for clinical trials of MRSA-BSI; (3) testing new strategies for "step-down" antibiotic therapy for MRSA-BSI; (4) management of staphylococcal BSIs in neonatal intensive care units; and (5) defining the impact of VRE bacteremia and daptomycin susceptibility on patient outcomes. This article outlines accomplishments, priorities, and challenges for research of infections caused by gram-positive organisms.

    Priorities and Progress in Gram-positive Bacterial Infection Research by the Antibacterial Resistance Leadership Group: A Narrative Review
    (2023) Doernberg, Sarah; Arias, Cesar; Altman, Deena; Babiker, Ahmed; Boucher, Helen; Creech, C Buddy; Cosgrove, Sara; Evans, Scott; Fowler, Vance; Fritz, Stephanie; Hamasaki, Toshimitsu; Kelly, Brendan; Leal, Sixto; Liu, Catherine; Lodise, Thomas; Miller, Loren; Munita, Jose M.; Murray, Barbara; Pettigrew, Melinda; Ruffin, Felicia; Scheetz, Marc; Shopsin, Bo; Tran, Truc; Turne, Nicholas; Williams, Derek; Zaharoff, Smitha; Holland, Thomas; Antibacterial Resistance Leadership Group
    The Antibacterial Resistance Leadership Group (ARLG) has prioritized infections caused by gram-positive bacteria as one of its core areas of emphasis. The ARLG Gram-positive Committee has focused on studies responding to 3 main identified research priorities: (1) investigation of strategies or therapies for infections predominantly caused by gram-positive bacteria, (2) evaluation of the efficacy of novel agents for infections caused by methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant enterococci, and (3) optimization of dosing and duration of antimicrobial agents for gram-positive infections. Herein, we summarize ARLG accomplishments in gram-positive bacterial infection research, including studies aiming to (1) inform optimal vancomycin dosing, (2) determine the role of dalbavancin in MRSA bloodstream infection, (3) characterize enterococcal bloodstream infections, (4) demonstrate the benefits of short-course therapy for pediatric community-acquired pneumonia, (5) develop quality of life measures for use in clinical trials, and (6) advance understanding of the microbiome. Future studies will incorporate innovative methodologies with a focus on interventional clinical trials that have the potential to change clinical practice for difficult-to-treat infections, such as MRSA bloodstream infections.
