Evaluation of the Pneumonia Panel on laboratory samples from an Italian pediatric center: results from a monocentric study.

Lower respiratory tract infections (LRTI) are still burdened by considerable morbidity and mortality. Rapid and appropriate treatment imply knowledge of the underlying causative pathogen; while it is tempting to offer broad spectrum antibiotics, Antimicrobial Stewardship Practices invite a judicious use of the latter, especially when bacteria are not the cause. However, the epidemiology shifts to multidrug resistant (MDR) pathogens that require optimization of molecules in order to provide optimal treatment. Novel methods requiring direct sample result testing such as the Biofire Pneumonia (PN) panel have recently been made available on the market. Syndromic testing may hence provide support in the diagnosis of LRTI. There is paucity of data concerning experiences in high MDR settings, and even less concerning the performance of these panels in pediatric settings with moderate MDR prevalence. Our study highlights the optimal sensitivity and importance of support from such methods in settings burdened by MDR presence and where fast and appropriate therapy is mandatory.
