This is a retrospective single-center study of 24 patients who received ceftazidime-avibactam plus aztreonam (CZA/ATM) for the treatment of VIM-type-producing Gram-negative bacillus (GNB) infections. The bacteria isolated were in 22 patients and Pseudomonas aeruginosa in 2. Sixteen out of 19 isolates showed synergistic activity. Two patients presented clinical failure at day 14, and the 30-day mortality was 17% (4/24). CZA/ATM could be considered an alternative therapy for VIM-type-producing GNB infections.

Objective: The emergence of multidrug-resistant (MDR) Escherichia coli strains has significantly constrained antibiotic treatment options, while the spread of antimicrobial resistance genes (ARGs) and mobile genetic elements exacerbates the situation. This study delves into an MDR E. coli strain, QMM-01, which uniquely co-expresses β-lactamases from all four recognized classes, aiming to uncover the underlying mechanisms of its resistance and assess its potential for global spread.

Background: Carbapenem-resistant Gram-negative bacteria (CR-GNB) develop resistance to many antimicrobials. To effectively manage infections caused by these organisms, novel agents and/or combinations of antimicrobials are required.

Objectives: Evaluated the in vitro efficacy of ceftazidime/avibactam in combination with other antimicrobials against CR-GNB.

Treatment options are limited for infections caused by carbapenem-resistant Klebsiella pneumoniae (CRKP) isolates due to the production of metallo-β-lactamase (MBL). The ceftazidime-avibactam (CZA)/ aztreonam (ATM) combination represents a new therapeutic approach in MBL-positive isolates. Our study aims to determine distribution of carbapenemase genes in CRKP isolates and to investigate the in vitro synergistic effect of the CZA/ATM combination.

Introduction: Infections caused by multidrug-resistant gram-negative bacilli (MDR-GNB) in critically ill patients present a challenge for timely and appropriate antibiotic treatment. This is particularly important in patients undergoing extracorporeal life-support techniques such as renal replacement therapy and extracorporeal membrane oxygenation. These techniques can introduce additional pharmacokinetic alterations, potentially leading to suboptimal exposure to antibiotics.

Background: MDR/XDR constitutes a difficult to treat bacteria in a number of infections as there are few therapeutic options. Promising drugs in such cases can be cefiderocol, aztreonam and ceftazidime/avibactam or meropenem/vaborbactam.

Case Presentation: A 72-year-old female patient with sepsis caused by KP NDM, OXA 48 was admitted to the Intensive Care Unit, immediately after an emergency graftectomy (of a recently transplanted kidney) complicated with bleeding.
