Infective endocarditis-induced crescentic glomerulonephritis dramatically improved by plasmapheresis.
A 50-year-old woman was referred to our hospital because of skin purpura, anemia, high fever, and acute renal insufficiency. Five years ago, she had been diagnosed as having ventricular septal defect without any complications. A blood culture drawn during the hospitalization grew Streptococcus viridans. She was diagnosed as having infective endocarditis-induced crescentic glomerulonephritis (GN) according to echocardiography and renal biopsy results. Although antibiotic treatment alone showed no apparent efficacy, after the initiation of plasmapheresis, the high fever and acute renal insufficiency were dramatically improved. After clinical stability was achieved, closure of the ventricular septal defect was performed. This result suggests that plasmapheresis may be beneficial in the treatment of infective endocarditis-induced crescentic GN. The possible mechanisms of this therapy are discussed.
