A Case of Crescentic Glomerulonephritis Associated with Bacterial Endocarditis

Abstract

A 25-year-old male presented with mitral insufficiency, perimembranous type of ventricular septal defect, pulmonary edema and renal insufficiency. The initial serum creatinine level was 16.2mg/dl. Blood cultures were positive for Streptococcus viridans and appropriate antibiotic therapy was initiated. Renal biopsy revealed diffuse proliferative glomerulonephritis with crescents involving all of the glomeruli. Even after adequate duration of treatment with antibiotics, surgical therapy, and high dose steroid therapy, renal function did not recover and the patient ended up with continuous ambulatory peritoneal dialysis. We present a case of crescentic glomerulonephritis associated with bacterial endocarditis with a review of the literature.
