RT Journal Article SR Electronic T1 New antibiotics for Gram-negative pneumonia JF European Respiratory Review JO EUROPEAN RESPIRATORY REVIEW FD European Respiratory Society SP 220119 DO 10.1183/16000617.0119-2022 VO 31 IS 166 A1 Bassetti, Matteo A1 Magnè, Federica A1 Giacobbe, Daniele Roberto A1 Bini, Lorenzo A1 Vena, Antonio YR 2022 UL https://publications.ersnet.org//content/31/166/220119.abstract AB Pneumonia is frequently encountered in clinical practice, and Gram-negative bacilli constitute a significant proportion of its aetiology, especially when it is acquired in a hospital setting. With the alarming global rise in multidrug resistance in Gram-negative bacilli, antibiotic therapy for treating patients with pneumonia is challenging and must be guided by in vitro susceptibility results. In this review, we provide an overview of antibiotics newly approved for the treatment of pneumonia caused by Gram-negative bacilli. Ceftazidime-avibactam, imipenem-relebactam and meropenem-vaborbactam have potent activity against some of the carbapenem-resistant Enterobacterales, especially Klebsiella pneumoniae carbapenemase producers. Several novel antibiotics have potent activity against multidrug-resistant Pseudomonas aeruginosa, such as ceftazidime-avibactam, ceftolozane-tazobactam, imipenem-relabactam and cefiderocol. Cefiderocol may also play an important role in the management of pneumonia caused by Acinetobacter baumannii, along with plazomicin and eravacycline.Thanks to new antibiotics, there is hope in the future regarding treatment of pneumonia caused by Gram-negative bacilli. https://bit.ly/3sl2sVw
