Pneumococcal endoprosthetic pulmonary valve endocarditis with crescentic glomerulonephritis and acute renal failure

We describe a case of acute renal failure with crescentic glomerulonephritis, due to pneumococcal infective endocarditis on an endoprosthetic pulmonary valve. The patient's renal insufficiency subsequently improved following eradication of the microbe with antibiotics alone. Moreover, this is the first description of pneumococcal PVE leading to a crescentic glomerulonephritis.
