“…To our knowledge, this is the first study in which BrRNA RT-qPCR was used in a clinical setting to detect bacterial pathogens. The detection rate obtained by the BrRNA RT-qPCR assay was markedly higher than that obtained from the standard blood culture in this study, which was comparable to the detection rate reported in the literature (4,6,7,19). BrRNA RT-qPCR may be a more sensitive technique because it can detect bacteria that grow poorly in culture media.…”

“…Because bacterial infection is considered to be the most common cause of this complication, which can be life threatening if untreated, it is recommended that antibiotic treatment be started immediately when neutropenic patients develop fever (10,17,18). However, blood culture, a current standard microbiological assessment for febrile neutropenic patients, can identify pathogens in only 10 to 37% of these patients (4,6,7,19) and can take more than 24 h to yield a report. Therefore, the majority of cases are treated empirically with broad-spectrum antibiotics and without microbiological evidence to support the treatment.…”

“…Se define como la reducción en el recuento absoluto de neutrófilos en la sangre por debajo de 1500 células/mm 3 , la cual está determinada por la suma de segmentados y cayados. En la tabla 1 se puede observar la clasificación según el recuento celular, y teniendo en cuenta esta, se tomará como neutropenia severa un recuento de neutrófilos menor o igual a 500 células/mm 3 o conteo entre 500 y 1000 células/mm 3 con una caída brusca entre el 25% y 50% del valor en la última semana 9 .…”

“…En un estudio realizado en el Hospital Universitario de Santander en el periodo comprendido entre enero del 2007 y enero 2008, el 78% de los episodios de neutropenia febril correspondieron a pacientes con neoplasia hematolinfoide 11 . etiología Al analizar la causa de la fiebre, los estudios indican que la mayoría de los casos son secundarios a una infección 3,13,15 ; pudiendo ser de origen viral, fúngica o bacteriana, siendo la infección bacteriana la complicación más frecuente con presentación más temprana durante el episodio febril en un paciente neutropénico 2 . La identificación del origen de la infección se logra solo en el 30% a 50% de los casos 15,17 , y cuando se reconoce el foco, este generalmente corresponde a infecciones del tracto respiratorio superior e inferior como neumonía, sinusitis y otitis, estas dos últimas en menor frecuencia 3,15,18 .…”
