Endocarditis por Bordetella holmesii en un paciente asplénico / [Bordetella holmesii endocarditis in an asplenic patient].

ABSTRACT

The case of a 52-year-old female patient with a history of critical aortic stenosis, hypothyroidism and splenectomy as treatment for her Hodgkin’s lymphoma is herein presented. In April 2011, the patient was admitted to the cardiology service due to global heart failure, fever and poor response to diuretic and vasodilator therapy. A transesophageal echocardiogram showed images compatible with vegetations in the aortic, pulmonary, and mitral valves. A diagnosis of infective endocarditis was made. Growth of gram-negative coccobacilli was observed in two blood culture sets. The microorganism was finally identified as Bordetella holmesii. The patient was treated with ceftriaxone 1 g every 12 hours for 28 days with favorable outcome.
