Endocarditis por Rothia aeria / Rothia aeria endocarditis. case report

Resumen Paciente de sexo femenino de 65 años, con antecedentes de hipertensión arterial crónica, resistencia a la insulina, histerectomía total y fractura tibioperonea antigua, es hospitalizada por cuadro febril, sin foco, de 2 meses de evolución, con sospecha de endocarditis por parámetros inflamatorios elevados y soplo diastólico en foco aórtico 2/6. Se estudia con ecocardiograma, transtorácico (ETT) y transesofágico (ETE), que muestra vegetación en velo aórtico coronario izquierdo de 9 mm por 7 mm e insuficiencia aórtica leve, motivo por el cual se toma hemocultivo resultando positivo para Rothia aeria. La paciente evoluciona con embolia de riñón derecho y bazo, y posteriormente, con hemorragia subaracnoidea. Inicia tratamiento antibiótico con ampicilina, vancomicina y gentamicina, con lo cual presenta una evolución satisfactoria y es dada de alta luego de 28 días de hospitalización. Al revisar la literatura, se puede llegar a la conclusión de que la endocarditis por Rothia es extremadamente infrecuente y que, en cuanto al cuadro clínico, tiene tendencia a una forma de presentación subaguda, con presencia de vegetaciones grandes mayores a 10mm y un alto grado de complicaciones neurológicas.

Abstract A 65-year-old female patient, with a history of chronic hypertension, insulin resistance, total histerectomy, and tibioperoneal fracture, is hospitalized for fever of unknown etiology. Basterial endocarditis was suspected due to elevated inflammatory parameters and a 2/6 diastolic murmur present in the aortic focus. Transthoracic and transesophageal echocardiography, showed a 9 mm by 7 mm vegetation in the left coronary aortic leaflet of and mild aortic insufficiency, Blood cultures were positive for Rothia aeria. She developed embolism of the right kidney and spleen, and subsequently, a subarachnoid hemorrhage. Antibiotic therapy was initiated with ampicillin, vancomycin and gentamicin, with a satisfactory evolution being discharged after 28 days of hospitalization. When reviewing the literature, it can be concluded that Rothia endocarditis is extremely rare and that, tends to have a subacute presentation with large vegetations, larger than 10 mm, and a high incidence of neurological complications.

Rothia aeria endocarditis in a patient with a bicuspid aortic valve: case report

Rothia aeria is an uncommon pathogen mainly associated with endocarditis in case reports. In previous reports, endocarditis by R. aeria was complicated by central nervous system embolization. In the case we report herein, endocarditis by R. aeria was diagnosed after acute self-limited diarrhea. In addition to the common translocation of R. aeria from the oral cavity, we hypothesize the possibility of intestinal translocation. Matrix-assisted laser desorption ionization-time of flight mass spectrometry and genetic sequencing are important tools that can contribute to early and more accurate etiologic diagnosis of severe infections caused by Gram-positive rods.
