Incidental detection of Corynebacterium jeikeium endocarditis via regular blood examination in an afebrile hemodialysis patient

AbstractHerein, we describe a rare case ofCorynebacterium jeikeium endocarditis that silently progressed in a 65-year-old man undergoing hemodialysis. Because routine monthly blood examination revealed high C-reactive protein levels, blood cultures were collected, although he had no symptom and was afebrile. After 2  days, a Gram-positive rod was detected in one set of the blood culture. Furthermore, transthoracic echocardiography revealed new aortic regurgitation (AR) and vegetations, and, therefore, infective endocarditis was suspected. Transesophageal echocardiography showed vegetations with a maximum diame ter of 8 mm on his aortic valve, with some valve destruction.C. jeikeium was identified in three sets of blood cultures. Administration of daptomycin was started because he had vancomycin allergy. Judging from the high risk of embolization due to vegetations, emergency aortic valve replacement was performed on the second day.C. jeikeium was detected in a resected cardiac valve specimen and blood. This case emphasizes that physicians should always consider the possibility of infective endocarditis even in hemodialysis patients without any symptoms.
