Diffuse Crescentic Glomerulonephritis in Bacterial Endocarditis: A Case Report

Renal involvement is common in patients with bacterial endocarditis. Very rarely, patients may present with an extensive glomerular epithelial crescent formation with a rapid deterioration in renal function. We report a 9-years old female patient with endocarditis and crescentic glomerulonephritis with impaired renal function. We tried a brief course of corticosteroid therapy and appropriate antibiotic due to hypocomplementemia. Appropriate antibiotic therapy is essential to eradicate the infection. A brief course of corticosteroid therapy may be helpful in those with deteriorating renal function. Plasmapheresis may be useful in those with persistent hypocomplementemia.
