The study evaluated the characteristics of NFGNBs infections in children and the risk factors for bloodstream infections. Carbapenem-resistant NFGNBs infections were common in children with severe and prolonged neutropenia, and were associated with prior antimicrobial use and intensive care unit admission.
Introduction: Non-fermentative Gram-negative bacterias (NFGNBs) are a major cause of life threatening infections in hospitalized children. In this study, we aimed to evaluate the demographic and clinical characteristics of NFGNBs infections and identify the risk factors and outcomes of bloodstream infections (BSIs) caused by carbapenem-resistant (CR) NFGNBs infections. Methods: A retrospective cohort was designed to evaluate the patients with a BSI caused by NFGNBs between in January 2014 and December 2017. Results: A total of 131 episodes from 115 patients were evaluated. The mean age of the patients was 4.79 +/-(4.74) year. The most commonly isolated NFGNBs species was Acinetobacter spp. (35.9%), Pseudomonas spp. (34.4%), and Stenotrophomonas maltophilia (13%). The rate of carbapenem-resistance was 38.2% in Acinetobacter spp. and 26.6% in Pseudomonas spp. The comparison of CR group with carbapenem-susceptible (CS) group showed statistical significance for the length of hospital stay prior to onset of infection and total hospital stay (P values were 0.001, 0.008). Based on the univariate analysis, requirement of mechanical ventilation, central venous catheter, nasogastric tube, Foley catheter, severe neutropenia (<100/mm3), prolonged neutropenia (>14 days), prior intensive care unit admission and prior antimicrobial treatment (carbapenems, colistin, glycopeptide) were more common in carbapenemresistant NFGNBs infections (P values are 0.001, 0.012, 0.000, 0.005, 0.042, 0.027, 0.007, 0.007). In patients with NFGNBs infections 14-day and 30-day mortality rates were %16.8 and 21.4%. Conclusion: CR infections were more common in children with prolonged and severe neutropenia. Prior antimicrobial use and intensive care unit admission were more common in CR infections. (c) 2021 Japanese Society of Chemotherapy and The Japanese Association for Infectious Diseases.
