Corynebacterium jeikeium, a pleomorphic Gram-positive bacillus, is a common component of the cutaneous microbiota, usually considered as a contaminant, with little pathogenic potential. However, its role in various types of infections, such as bacteremia, sepsis, endocarditis (IE) and infection of prosthetic material is gradually being proven. Few cases of IE due to Corynebacterium jeikeium have been described in the literature. The aim of this article was to describe four cases of IE due to Corynebacterium jeikeium diagnosed in our hospital between May 2021 and April 2022, as well as to conduct a narrative review of the literature on this entity. After analysis, we highlight that 65.6% were men, 81.3% were valve or intravascular device carriers, and IE cases presented early, before one year after surgery. The most affected valve was the aortic valve (68.8%), followed by the mitral valve (21.1%). Valve replacement was performed in 65.6% of cases, and the most commonly used antibiotic was vancomycin (68.8%) at a dose of 15 mg/kg/12 h. With respect to prognosis, the overall mortality rate was 21.9%. The comparative results between our series and the literature review were similar except for a higher mortality rate (50%) and the use of dalbavancin in the treatment. We go on to review previously reported cases, along with four cases described in our hospital, of C. jeikeium endocarditis and will discuss various aspects of C. jeikeium infection, focusing on microbiology, pathophysiology, and treatment.
