Executive summary of the consensus document of the Spanish Society of Infectious Diseases and Clinical Microbiology (SEIMC) on the diagnosis and antimicrobial treatment of infections due to carbapenem-resistant Gram-negative bacteria / Resumen ejecutivo del documento de consenso de la Sociedad Española de Enfermedades Infecciosas y Microbiología Clínica (SEIMC) sobre el diagnóstico y tratamiento antimicrobiano de las infecciones por bacterias gramnegativas resistentes a carbapenémicos

Infections caused by multidrug resistant Gram-negative bacteria are becoming a worldwide problem due to their increasing incidence and associated high mortality. Carbapenem-resistant bacteria such as Klebsiella pneumoniae, Pseudomonas aeruginosa and Acinetobacter baumannii are the most important in clinical practice. The objective of these guidelines is to update the recommendations for the diagnosis and treatment of infections caused by these multidrug resistant bacteria. Although ‘old’ antibiotics such as aminoglycosides, colistin, or tigecycline are frequently used for therapy of these bacteria, the ‘new’ beta-lactams such as ceftazidime–avibactam, ceftolozane–tazobactam, meropenem–vaborbactam, imipenem–cilastatin–relebactam or cefiderocol are progressively becoming the first-line therapy for most of these microorganisms. The Spanish Society of Infectious Diseases and Clinical Microbiology (Sociedad Española de Enfermedades Infecciosas y Microbiología Clínica) designated a panel of experts in the field to provide evidence-based recommendations in response to common clinical questions. This document is primarily focused on microbiological diagnosis, clinical management, and targeted antimicrobial therapy of these infections, with special attention to defining the role of the new antimicrobials in the treatment of these bacteria.(AU)

Las infecciones causadas por bacterias gramnegativas multirresistentes se han convertido en un problema mundial debido a su creciente incidencia y alta mortalidad asociada. Las bacterias resistentes a carbapenémicos como Klebsiella pneumoniae, Pseudomonas aeruginosa y Acinetobacter baumannii son las más importantes en la práctica clínica. El objetivo de este documento de consenso es actualizar las recomendaciones sobre diagnóstico y tratamiento de las infecciones causadas por estas bacterias multirresistentes. Aunque los antibióticos ‘antiguos’ como aminoglucósidos, colistina o tigeciclina se utilizan con frecuencia en el tratamiento de estas bacterias, los ‘nuevos’ betalactámicos como ceftazidima-avibactam, ceftolozano-tazobactam, meropenem-vaborbactam, imipenem-cilastatina-relebactam o cefiderocol se están convirtiendo de forma progresiva en el tratamiento de primera elección para la mayoría de estos microorganismos. La Sociedad Española de Enfermedades Infecciosas y Microbiología Clínica ha designado un grupo de expertos en la materia para elaborar una guía de recomendaciones basadas en la evidencia sobre las cuestiones clínicas más habituales. Este documento está principalmente centrado en el diagnóstico microbiológico, el manejo clínico y el tratamiento dirigido de estas infecciones, con especial referencia a definir el papel de los nuevos antimicrobianos en el tratamiento de estas bacterias.(AU)
