Prosthetic valve endocarditis caused by Aerococcus Urinae

Abstract

Infective endocarditis (IE) caused by Aerococcus urinae is rare. The true incidence rate of this pathogen is likely underestimated as this is easily misidentified as Staphylococci or Streptococci . It is also associated with increased risk of complications such as systemic emboli. Aerococcus usually affects elderly males with underlying urological conditions. Here we present a case of IE with this rare Aerococcus urinae in a young man with a bioprosthetic aortic valve, despite negative urine cultures.

Aerococcus Urinae Endocarditis: A Case Report and Literature Review

“…Among the antibiotic regimens used, the most common treatment course involved approximately 72% of the 50 cases receiving beta-lactam therapy with an aminoglycoside for an average duration of approximately six weeks, which resulted in approximately 78% of patients treated in this manner surviving. AG: aminoglycoside, Van: vancomycin, BPH: benign prostatic hyperplasia, ASD: atrial septal defect, TURP: trans-urethral resection of the prostate Data from: (Ludhwani, 2020) [3], (Yabes, 2018) [12], (Tai, 2021) [14], (Feghaly, 2022) [16], (Lattanzio, 2020) [17], (Bathania, 2019) [18], (Rosborough, 2020) [19], (Martín-Guerra, 2020) [20], (Ahmed, 2021) [21], (Varughese, 2021) [22], (Khan, 2021) [23]…”

Aero to the heart: A case of aortic valve endocarditis caused by Aerococcus Urinae in an elderly woman

“…It has been associated with balanitis, soft tissue infections, and septicemia, as well as, endocarditis, which is the most common presentation for disseminated aerococcal bacteremia 2 , 4 . IE vegetation often involves the aortic valve, followed by the mitral valve in order of prevalence, and may increase in mortality due to complications for embolic events, cardiogenic shock, stroke, renal failure, disseminated intravascular coagulation, or aortic wall ulceration 5 , 6 .…”
