RT Journal Article SR Electronic T1 Neisseria elongata subsp elongata infective endocarditis following endurance exercise JF BMJ Case Reports FD BMJ Publishing Group Ltd SP bcr2015212415 DO 10.1136/bcr-2015-212415 VO 2015 A1 Joanne May Jenkins A1 Amanda Fife A1 Max Baghai A1 Rafal Dworakowski YR 2015 UL http://casereports.bmj.com/content/2015/bcr-2015-212415.abstract AB A 31-year-old Argentinian woman presented with a 3-week history of fever, night sweats, myalgia and lethargy following a work trip to Uganda where she ran a marathon. Malarial screens were negative but C reactive protein, erythrocyte sedimentation rate and neutrophil count were raised and she was anaemic. A new pansystolic murmur was heard over the mitral valve and the transthoracic echocardiogram showed a large vegetation (>1 cm) with at least moderate mitral regurgitation. Blood cultures grew Neisseria elongata, subsp elongata treated initially with ceftriaxone then oral ciprofloxacin to complete 4 weeks of treatment. CT scan revealed a wedge-shaped area of low attenuation in the spleen in keeping with a splenic infarct. Seven days postadmission, the patient underwent a successful mitral valve repair. Recovery was complicated by a likely embolic infarct in the right frontal lobe, but the patient was discharged 12 days postoperative with no neurological sequelae.
