Abstract

Globally, the adoption of Solid Organ Transplantation (SOT) as first-line therapy for end-stage organ failure has not come without its share of complications. Enterococcal endocarditis poses a substantial risk to renal transplant patients, and multiple factors must be considered due to the grave nature of this infection. Such factors include addressing multidrug-resistant organisms, antibiotic therapy-related toxicity, and preserving the transplanted organ. Additional considerations include salvaging an affected cardiac valve and avoiding the need for a valve replacement with the attendant complications. Ampicillin and gentamicin have historically been the standard of care as first-line treatment for many years until the aminoglycoside sparing regimen of ampicillin and ceftriaxone showed non-inferiority in clinical studies. We present a second case report with an aminoglycoside sparing regimen of ampicillin and daptomycin in a renal transplant patient who developed Enterococcus faecalis endocarditis. We conclude with a brief review of published research with this combination.
