Characterization of Enterococcus Faecalis Endocarditis and Impact of Amoxicillin MIC Elevation on Patient Outcome

Infective endocarditis is a complex infection that can be life-threatening. These infections also cause anatomical lesions that can be severe. Their management is complex and involves several disciplines: cardiology, bacteriologists, infectious diseases specialists, radiologists, nuclear medicine specialists, cardiac surgeons, neurologists, pharmacologists, etc. The incidence of Enterococcus faecalis endocarditis is increasing due to the aging of the population and the disappearance of rheumatic fever. The adequate management of these infections is complex and relies on the prolonged administration of high-dose antibiotics, classically the combination of amoxicillin and ceftriaxone. In the context of Streptococcal endocarditis, the impact of increasing the Minimum Inhibitory Concentration (MIC) of amoxicillin on patient mortality has been demonstrated but no study has yet examined the impact of increasing the MIC of amoxicillin on the outcome of patients treated for Enterococcus faecalis infective endocarditis.
