Abstract
Background
Multidrug-resistant (MDR) Gram-negative infections are challenging to treat in children, and polymyxin-based regimens are limited by toxicity. We evaluated the real-world use of ceftazidime-avibactam (CZA) as a potential polymyxin-sparing option for children with MDR Gram-negative infections.
Methods
We conducted a single-center retrospective comparative cohort study at a tertiary hospital in Istanbul, Türkiye. Children aged < 18 years who received definitive therapy for microbiologically confirmed MDR Gram-negative infections between January 2022 and May 2024 were included. The primary outcome was 28-day all-cause mortality. Secondary outcomes included clinical response, documented microbiological clearance, acute kidney injury (AKI), drug-induced liver injury (DILI) and one-year all-cause mortality.
