Three patients with endocarditis due to Candida species were treated with 5-fluorocytosine. One had endocarditis imposed on senile aortic sclerosis and survived and two had infections on prosthetic valves and died. In the latter two patients chemotherapy failed to eradicate the infection and was associated with marrow depression and possibly hepatic necrosis.

A 49-year-old black man with hypertension-induced chronic renal failure requiring hemodialysis and a history of arteriovenous access graft infection was admitted with Staphylococcus aureus sepsis, dyspnea, and peri-incisional erythema over his arteriovenous graft fistula. Results of a transthoracic echo demonstrated aortic sclerosis and concentric left ventricular hypertrophy. Results of a whole-body In-111 white cell (WBC) scan were negative over the arteriovenous graft site; however, an intense abnormal focus of labeled WBCs was evident to the left of the sternum. A subsequent transesophageal echocardiogram showed a mixed cystic-solid calcified mass adjacent the left aortic cusp. Surgery confirmed a perivalvular abscess. As a whole-body imaging modality, the In-111 WBC scintigram indicated the true location of the infectious process responsible for the patient's sepsis. The combination of echocardiography and radiolabeled WBC imaging increases sensitivity for detection of endocarditis/perivalvular abscess. Radiolabeled WBC imaging is more efficacious for monitoring therapy because the echocardiogram often does not change with treatment of endocarditis/perivalvular abscess.

We report the case of a 64-year-old man with Arcanobacterium pyogenes endocarditis. The patient presented with dyspnea and asymmetrical progressive quadriparesis. A transthoracic echocardiogram revealed mobile vegetations on both leaflets of his mitral valve measuring 0.5 x 3 cm, thickening of the mitral valve with severe mitral regurgitation due to dehiscence of the papillary muscle to the posterior mitral leaflet. He also had aortic sclerosis with a vegetation measuring 0.5 x 1 cm causing aortic valve dehiscence and free flow aortic regurgitation. An initial hemoculture grew out pleomorphic, gram-positive, non-motile, anaerobic to microaerophilic bacilli. A diagnosis of infective endocarditis was made using modified Duke criteria. He was treated with intravenous ampicillin and gentamicin. Four days after admission, he developed acute respiratory failure and succumbed to the disease. A pre-mortem hemoculture and post-mortem heart valve culture grew Arcanobacterium pyogenes. Septic thromboemboli involving the brain, kidneys, lungs and spleen were documented. The patient also had ischemic vasculopathy with focal spinal arteriolitis and bilateral demyelination of the cervical corticospinal tracts. There are three published reports of human A. pyogenes endocarditis in the literature. Neurological involvement with ischemic spinal vasculopathy and demyelination has not been reported. We report the first autopsy proven case of A. pyogenes infective endocarditis with ischemic spinal vasculopathy. We review the clinicopathologic features of systemic A. pyogenes infection.
