    Background There is little information about the efficacy of active alternative drugs to carbapenems except β-lactam/β-lactamase inhibitors for the treatment of bloodstream infections (BSIs) due to extended-spectrum β-lactamase–producing Enterobacteriaceae (ESBL-E). The objective of this study was to assess the outcomes of patients with BSI due to ESBL-E who received empiric therapy with such drugs (other active drugs [OADs]) or carbapenems. Methods A multinational retrospective cohort study of patients with BSI due to ESBL-E who received empiric treatment with OADs or carbapenems was performed. Cox regression including a propensity score for receiving OADs was performed to analyze 30-day all-cause mortality as main outcome. Clinical failure and length of stay were also analyzed. Results Overall, 335 patients were included; 249 received empiric carbapenems and 86 OADs. The most frequent OADs were aminoglycosides (43 patients) and fluoroquinolones (20 patients). Empiric therapy with OADs was not associated with mortality (hazard ratio [HR], 0.75; 95% confidence interval [CI], .38–1.48) in the Cox regression analysis. Propensity score–matched pairs, subgroups, and sensitivity analyses did not show different trends; specifically, the adjusted HR for aminoglycosides was 1.05 (95% CI, .51–2.16). OADs were neither associated with 14-day clinical failure (adjusted odds ratio, 0.62; 95% CI, .29–1.36) nor length of hospital stay. Conclusions We were unable to show that empiric treatment with OAD was associated with a worse outcome compared with carbapenems. This information allows more options to be considered for empiric therapy, at least for some patients, depending on local susceptibility patterns of ESBL-E.

    Factores de riesgo para Infecciones relacionadas con la Asistencia Sanitaria causadas por Enterobacteriaceae productoras de Klebsiella pneumoniae carbapenemase: un estudio de caso control
    (Murcia: Servicio de Publicaciones de la Universidad de Murcia, 2020) Alvim, André; Couto, Bráulio Roberto Gonçalves Marinho; Gazzinelli, Andrea
    Objetivo: Evaluar los factores de riesgo para infecciones relacionadas con la asistencia sanitaria causadas por Enterobacteriaceae productoras de carbapenemas. Método: Este es un estudio retrospectivo de casos y controles que consistió en una muestra de 82 pacientes infectados y 164 controles, totalizando 246 pacientes. La recopilación de datos se realizó entre enero y mayo de 2017 mediante la búsqueda en el Sistema Automatizado de Control de Infecciones Hospitalarias y en los registros electrónicos de pacientes. Resultados: Pacientes previamente colonizados con microorganismos gramnegativos (OR: 10.7, 95% CI: 2-60, p=0.007), con cáncer (OR: 20.8, 95% CI: 4-120, p<0.001), utilizando una catéter de doble luz (OR: 30.5, 95% CI: 2-382, p=0.008), con lesión por presión (OR: 136.2, 95% CI: 11- 1623, p<0.001) y permanecer en la Unidad de Cuidados Intensivos (OR: 1.4, 95% CI: 1.2-1.6, p <0.001) fueron más propensos a desarrollar infecciones causadas por Enterobacteriaceae productoras de carbapenemas que el grupo control. El área bajo la curva ROC mostró un buen rendimiento general (0,99; IC 95%: 0,992-0,998) del modelo de regresión logística final. Conclusión: La colonización previa, el cáncer, el uso de catéteres de doble luz, la lesión por presión y la estadía en la UCI fueron factores de riesgo muy importantes para la adquisición de infecciones en el entorno hospitalario.
