Risk Factors for and Outcomes of Bloodstream Infection Caused by Extended-Spectrum β-Lactamase–Producing Escherichia coli and Klebsiella Species in Children

Abstract: Receipt of extended-spectrum cephalosporins in the 30 days before infection by an Escherichia coli or Klebsiella species is significantly associated with having an ESBL-EK infection in hospitalized children. Curtailed use of cephalosporins among high-risk groups may reduce the occurrence of ESBL-EK infections. Future studies on identifying high-risk children and investigating the impact of curtailed third-generation cephalosporin use to limit additional emergence of ESBL-EK infections should be undertaken.

“…2,6 In addition, extended-spectrum ␤-lactamase and carbapenemase-producing E coli strains, such as were historically associated with nosocomial or health care-associated (HA) infections, are now prevalent in the community. 2,6,[12][13][14] Most studies that have examined antibiotic resistance among E coli isolates have included convenience samples, 1,2,4,5,[15][16][17][18][19] and only 2 have been population based. 20,21 Thus, it is unclear whether the increase in antibiotic-resistant E coli infections is disproportionately affecting specific patient groups.…”

“…El cálculo del tamaño muestral se realizó considerando un valor de OR de al menos 3, con nivel de error alfa de 0,05 bilateral y poder de 80%. Se consideró arbitrariamente como valor bajo la hipótesis nula, la tasa de BLEE encontrada en los controles del trabajo con el mejor diseño para este objeto: 17% 8 . Se incluyeron 3 controles por caso para mejorar el poder del diseño y facilitar el análisis estratifi cado.…”

“…En algunos estudios se ha observado que los pacientes que usan antibióticos en los 30 días previos a presentar una bacteriemia, tienen más riesgo de que ésta sea producida por una enterobacteria productora de BLEE. También tienen más riesgo aquellos pacientes sometidos a procedimientos invasivos (VMI, CVC, cirugía torácica y abdominal) y aquellos pacientes que se encuentran en Unidades de Cuidados Intensivos 2,[8][9][10] . Existen escasos estudios que caracterizan las infecciones pediátricas por estos microorganismos productores de BLEE [8][9][10] .…”
