摘要：

Although a variety of microorganisms have caused infective endocarditis, Nocardia species have rarely been reported as a causative agent of the disease. We describe a case of nocardial endocarditis, occurring to a 22-year-old Japanese woman during long-term corticosteroid therapy for adult-onset Still's disease and diagnosed after the rupture of cerebral mycotic aneurysm. Echocardiography showed that the causative organism, isolated from the blood and identified as Nocardia nova with an analysis of 16S ribosomal RNA sequences, affected the posterior papillary muscle of the left ventricle. Nocardia-like organisms were also detected in the pus around the raptured aneurysm. After treatment with imipenem/ cilastatin plus amikacin for 3 months followed by oral trimethoprim/sulfamethoxazole for 1 year, no relapse of nocardiosis occurred during a follow-up for 3 years. To our knowledge, the present case is the first reported endocarditis due to N. nova. (c) 2021 Japanese Society of Chemotherapy and The Japanese Association for Infectious Diseases.
