Aspectos microbiológicos de interés en el diagnóstico de la peritonitis bacteriana espontánea del paciente con cirrosis hepática
Resumen
La peritonitis bacteriana espontánea es una complicación grave del paciente cirrótico, con elevada mortalidad intrahospitalaria y pobre pronóstico a corto plazo. Su diagnóstico requiere un elevado índice de sospecha, la realización precoz de paracentesis abdominal para recuento del número de polimorfonucleares en líquido de ascitis y estudio bacteriológico. El cultivo en frascos de hemocultivo ha sustituido al método tradicional en placa de agar por su mayor rendimiento diagnóstico y su menor demora. La importancia de los estudios bacteriológicos tiene un renovado interés debido a los cambios reportados en la literatura en la causa de la infección en relación al uso de antibioticoterapia profiláctica, al aumento de infecciones nosocomiales, y al bajo rendimiento del estudio directo del líquido de ascitis. Esta metodología de estudio del líquido de ascitis ha permitido mejorar el diagnóstico de peritonitis bacteriana espontánea en el Hospital Pasteur. En medios sanitarios de escasos recursos económicos, podría ser apropiado cultivar el líquido de ascitis de pacientes cirróticos en frascos de hemocultivo sólo en casos de sospecha clínica o analítica de peritonitis bacteriana espontánea, o de inicio de terapéutica antibiótica, disminuyendo así el costo asistencial en relación a esta técnica de cultivo microbiológica.
