Aztreonam plus Clavulanate, Tazobactam, or Avibactam for Treatment of Infections Caused by Metallo-β-Lactamase-Producing Gram-Negative Bacteria.

ABSTRACT: Metallo-β-lactamase (MBL)-producing Gram-negative bacteria are often extremely resistant, leading to a real therapeutic dead end. Here, we evaluated the in vitro and in vivo efficacy of aztreonam in combination with ceftazidime-avibactam, ceftolozane-tazobactam, or amoxicillin-clavulanate for the treatment of infections caused by MBL-producing Enterobacteriaceae, MBL-producing Pseudomonas aeruginosa, and extremely drug-resistant Stenotrophomonas maltophilia First, we report two clinical cases, namely, a urinary tract infection caused by an NDM-5-producing Escherichia coli isolate and a pulmonary infection caused by a S. maltophilia isolate efficiently treated with the association of aztreonam-ceftazidime-avibactam and aztreonam-amoxicillin-clavulanate, respectively. Then, a total of 50 MBL
