Treatment of remains challenging, despite the availability ceftolozane-tazobactam. We report a treatment failure with ceftolozane-tazobactam salvage therapy for pneumonia complicated by lung abscess. Drug resistance, dose selection, and source control are possible contributing factors. Ceftolozane-tazobactam susceptibility testing should precede therapy and consideration should be given to dosing selection.

Background: Bacterial persistence is a phenomenon whereby a subpopulation of bacteria survive high concentrations of an active antibiotic in the absence of phenotypic alterations. Persisters are associated with chronic and recurrent infections for pathogens including Pseudomonas aeruginosa. Understanding persister profiles of newer antibiotics such as cefiderocol and ceftolozane/tazobactam against P.

Objectives: To investigate clinical outcomes of patients with Pseudomonas endocarditis and identify factors associated with treatment failure.

Methods: Adult patients meeting definitive Duke's criteria for Pseudomonas endocarditis at 11 hospitals were identified between May 2000 and February 2024. Failure was defined as death or microbiological failure by day 42.

Article Synopsis
  • * No significant survival advantage was found among most beta-lactam antibiotics, but the combination of meropenem and aerosolized colistin showed a reduction in mortality compared to intravenous colistin alone.
  • * Although ceftolozane/tazobactam showed potential superiority for microbiological cure, ceftazidime had a higher clinical failure rate compared to other treatments, and intravenous colistin was linked to more acute kidney failure in safety assessments.

Aim: To investigate the efficacy of intravenous (IV) fosfomycin as combination therapy for treatment of difficult-to-treat (DTT) acute and subacute infections with multi-drug-resistant (MDR) Gram-negative bacteria (GNB), and risk factors associated with 90-day mortality.

Methods: A retrospective, observational, monocentric study enrolled patients treated with IV fosfomycin in combination regimens (≥72 h) for proven DTT-MDR-GNB infection. Multi-variate regression analysis identified independent risk factors for 90-day mortality.
