Immunosuppressive therapy and plasmapheresis in rapidly progressive glomerulonephritis associated with bacterial endocarditis.
A 25-year-old male presented with new cardiac murmurs and acute renal insufficiency. Blood cultures grew Streptococcus viridans and appropriate antibiotic therapy was initiated. A renal biopsy revealed diffuse proliferative glomerulonephritis with crescents involving more than 50% of the glomeruli. Treatment with antibiotics, plasmapheresis, and steroids resulted in renal recovery that paralleled reductions in circulating immune complexes. The rationale for this therapeutic approach is discussed, as well as a review of two similar case reports. These experiences suggest a possible role for plasmapheresis and immunosuppressive drugs in patients who develop rapidly progressive glomerulonephritis as a complication of bacterial endocarditis.
