Staphylococcus aureus es un patógeno importante que causa cerca de 11% a 33% de las bacteriemias hospitalarias y un porcentaje importante de las adquiridas en la comunidad, con una tasa de complicaciones cercana a 50%. En la siguiente revisión se destaca la epidemiología de la bacteriemia por S. aureus, con especial referencia a la situación de este patógeno en Colombia, la frecuencia y los mecanismos de resistencia a los medicamentos más frecuentemente usados en este contexto, y se discuten los elementos semiológicos, clínicos y de laboratorio que influyen en el enfoque diagnóstico y terapéutico de los pacientes con bacteriemia por este microorganismo.Palabras clave: Staphylococcus aureus/patogenicidad, bacteriemia/terapia, bacteriemia/ epidemiología, agentes antibacterianos/uso terapéutico.
Therapeutic approach to Staphylococcus aureus bacteremiaStaphylococcus aureus is an important human pathogen, responsible for 11-33% of the bacteremias acquired in the hospital setting and nearly 50% of those acquired in the community at large. The epidemiology of S. aureus bacteremia is discussed, with an special emphasis on the situation in Colombia and the resistance mechanisms against the major drug groups used for the treatment. The clinical keys and laboratory support for the appropriate clinical approaches are presented together with the therapeutic strategies for the treatment of patients with S. aureus bacteremia.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
