Necrotizing Crescentic Glomerulonephritis Complicating Bivalvular Bacterial Endocarditis

In the setting of an increasing incidence of endocarditis in the United States, we report a patient with necrotizing crescentic glomerulonephritis (GN) associated with native valve bacterial endocarditis due to Streptococcus parasanguinis. He was started on appropriate antibiotic treatment and subsequent blood cultures showed no growth. However, due to continuing decline in kidney function, immunosuppressive therapy was started. Despite immunosuppressive therapy and antibiotics, renal function did not improve and chronic hemodialysis was required. Due to rarity of condition, there are no definite treatment guidelines available. Antibiotics, steroids, immunosuppressive agents can be of help in most cases. Further research in this regard may help with early diagnosis and better treatment modalities.
