Abstract

Capnocytophaga canimorsus is an Anaerobic Gram-Negative bacterium present in the oral microbiology of cats and dogs. It can produce infections in humans, being capable of causing severe complications with the development of septic shock. There are known cases where this bacterium developed medical complications like thrombotic microangiopathy and disseminated intravascular coagulation. We have the case of 79 years old male that developed thrombotic microangiopathy and splenic infarction linked to bacteraemia by Capnocytophaga canimorsus. Due to its severity, it was necessary to start renal replacement therapy and several sessions of plasmapheresis with good evolution.

Resumen

Capnocytophaga canimorsus es una bacteria anaerobia gramnegativa presente en la microbiología oral de gatos y perros. Puede producir infecciones en humanos, siendo capaz de provocar un diagnóstico severo con desarrollo de shock séptico. Existen casos descritos con complicaciones médicas como Microangiopatía Trombótica y Coagulación Intravascular Diseminada. Presentamos el caso de un varón de 79 años que desarrolló microangiopatía trombótica e infarto esplénico asociado a bacteriemia por Capnocytophaga canimorsus. Por su gravedad, fue necesario iniciar terapia de reemplazo renal y varias sesiones de plasmaféresis con buena evolución.

Palabras clave

Micrpangiopatía trombótica; Shock séptico; Bacteriemia; Daño renal
