L. Ades et al., BACTERIAL-ENDOCARDITIS ASSOCIATED WITH CRESCENTIC GLOMERULONEPHRITIS IN A KIDNEY-TRANSPLANT PATIENT, Transplantation, 66(5), 1998, pp. 653-654
Background. Endocarditis-induced crescentic glomerulonephritis is a we
ll-described complication in nontransplant patients. Its occurrence in
transplant patients has not been reported to date. Methods. A 50-year
-old man who had received a renal allograft 13 years before and been t
reated with prednisone, 10 mg/day, was admitted for progressive renal
failure, purpura, edema of the lower limbs, and fever. Results. Blood
cultures isolated Streptococcus bovis and cardiac ultrasound examinati
on revealed a 23-mm-large vegetation on the mitral valve. His plasma c
reatinine level was 478 mu mol/L and his proteinuria was 5.5 g/day. A
renal biopsy showed diffuse crescentic glomerulonephritis. Long-term a
ntibiotic treatment and three methylprednisolone pulses were effective
in treating the endocarditis and glomerulonephritis. Conclusion. Endo
carditis-induced glomerulonephritis is an immune-mediated disease that
can also occur on a renal allograft. It is likely that a low daily do
se of immunosuppressive treatment may have been a facilitating factor.
