Precision medicine for the diagnosis and treatment of carbapenem-resistant Enterobacterales: time to think from a different perspective.

Abstract:

INTRODUCTION:Carbapenem-resistant Enterobacterales (CRE) represent a global public health problem. Precision medicine (PM) is a multicomponent medical approach that should be used to individualize the management of patients infected with CRE. AREAS COVERED:Here, we differentiate carbapenem-producing CRE (CP-CRE) from non-CP-CRE and the importance of this distinction in clinical practice. The current phenotypic CRE-case definition and its implications are also discussed. Additionally, we summarize data regarding phenotypic and molecular diagnostic tools and available antibiotics. In order to review the most relevant data, a comprehensive literature search of peer-reviewed articles in PubMed and abstracts presented at high-impact conferences was performed. EXPERT OPINION:PM in CRE infections entails a multi-step process that includes applying the current phenotypic definition, utilization of the right phenotypic or molecular testing methods, and thorough evaluation of risk factors, source of infection, and comorbidities. A powerful armamentarium is available to treat CRE infections, including recently approved agents. Randomized controlled trials targeting specific pathogens instead of site of infections may be appropriate to fill in the current gaps. In light of the diverse enzymology behind CP-CRE, PM should be employed to provide the best therapy based on the underlying resistance mechanism.
