Rothia dentocariosa sepsis in a pediatric renal transplant recipient having post-transplant lymphoproliferative disorders.

BACKGROUND

Rothia dentocariosa (RD) is a Gram-positive rod that colonizes the human oral cavity and can cause infective endocarditis.

RESULT: We report on a six-yr-old boy who underwent renal transplantation for polycystic kidney disease at the age of eight months. He developed post-transplant lymphoproliferative disorders after four yr and progressive graft failure. Following chemotherapy, the patient presented with neutropenia and sepsis. RD was isolated from blood and treatment with piperacillin/tazobactam was initiated; however, the child died because of multiorgan failure.

DISCUSSION: To the best of our knowledge, this is the first case of RD sepsis in a pediatric solid organ transplant recipient.
