ABSTRACT

Resumen Introducción: La neumonía asociada a ventilación mecánica (NAVM) es frecuente en pacientes críticos con COVID-19. Su diagnóstico precoz es fundamental para su pronóstico. Objetivo: Demostrar la utilidad del panel FilmArray Pneumo (PFA-P) en la confirmación o descarte de NAVM en estos pacientes. Métodos: Estudio retrospectivo de 71 pacientes críticos con COVID-19 con sospecha de NAVM en quienes se realizó cultivos y PFA-P para confirmación diagnóstica. Se describen las características clínicas, microbiología y mortalidad. Se define la validez y seguridad de PFA-P. Resultados: El uso de FAP-P y cultivos descartó NAVM en 29 pacientes (40,8%). En 41 pacientes se confirmó NAVM y la mortalidad a 30 días fue 48,8%. Se estudiaron 48 muestras, los cultivos fueron positivos en 30 (62,5%) y se detectaron 33 bacterias, PFA-P detectó 32 de estas 33 bacterias; 37 bacterias fueron detectadas exclusivamente por PFA-P. Las bacterias prevalentes fueron Klebsiella pneumoniae (31,4%) Pseudomonas aeruginosa (21,4%) y Acinetobacter calcoaceticusbaumannii (14,2%). La sensibilidad, especificidad, valor predictor positivo y valor predictor negativo de PFA-P con respecto a cultivos fue 96,9%, 92,5%, 46,4% y 99,8, respectivamente. Un paciente tuvo NAVM por Burkholderia cepacia bacteria no detectada por FAP-P. Conclusiones: La FAP-P es una técnica molecular eficaz para descartar y diagnosticar la NAVM permitiendo una suspensión rápida de los antimicrobianos o un tratamiento dirigido temprano.


Abstract Background: Ventilator-associated pneumonia (VAP) is frequent in critical COVID-19 patients. Its early diagnosis is essential for its prognosis. Aim: To demonstrate the usefulness of the FilmArray Pneumo panel (FAP-P) in confirming or ruling out VAP in these patients. Methods: Retrospective study of 71 critical COVID-19 patients with suspected VAP in whom cultures and FAP-P were performed for diagnostic confirmation. Clinical characteristics, microbiology and mortality are described. The validity and safety of FAP-P is defined. Results: The use of FAP-P and cultures ruled out VAP in 29 patients (40.8%). In 41 patients, VAP was confirmed and the 30-day mortality was 48.8%. Forty-eight samples were studied, the cultures were positive in 30 (62.5%) and 33 bacteria were detected, FAP-P detected 32 of these 33 bacteria; 37 bacteria were exclusively detected by PFA-P. The most prevalent bacteria were Klebsiella pneumoniae (31.4%), Pseudomonas aeruginosa (21.4%) and Acinetobacter calcoaceticus-baumannii (14.2%). The sensitivity, specificity, positive predictive value and negative predictive value of FAP-P with respect to cultures were 96.9%, 92.5%, 46.4% and 99.8%, respectively. One patient had VAP due to Burkholderia cepacia bacteria not detected by FAP-P. Conclusions: FAP-P is an effective molecular technique to rule out and diagnose VAP, allowing rapid suspension of antibiotics or early targeted treatment.
