Diffuse proliferative glomerulonephritis and acute renal failure associated with acute staphylococcal osteomyelitis.

Abstract

A 72-year-old man developed acute renal failure after coronary bypass surgery that had been complicated by sternal osteomyelitis caused by the Staphylococcus aureus bacterium. Bacteremia and sepsis were not present. Renal biopsy demonstrated a florid, diffuse, proliferative glomerulonephritis with glomerular immune complex deposition. Management included hemodialysis, prolonged antibiotic therapy, and repeated surgical debridement. Spontaneous recovery of renal function occurred after eradication of infection and final surgical wound repair. The relationship between acute bacterial infections and glomerulonephritis and, in particular, the causal role of staphylococcal antigens in the pathogenesis of such lesions is discussed.
