Native Mitral Valve Endocarditis Caused by a Non-HACEK Gram-Negative Pathogen in a Hemodialysis Patient.

Infective endocarditis (IE) due to non-HACEK (species other than ) bacteremia accounts for less than 2% of all IE cases but is proven to be associated with higher mortality, even more so in hemodialysis (HD) patients. Few data are available in the literature concerning non-HACEK Gram-negative (GN) IE in this immunocompromised population with multiple comorbidities. We report the atypical clinical presentation of an elderly HD patient diagnosed with a non-HACEK GN IE, namely , successfully treated with intravenous (IV) antibiotics.
