RESUMO
Fibrillary glomerulonephritis is an uncommon disease seen in approximately 1% of all native kidney biopsy specimens. We present here a case of a 40-year-old white woman with the rapid loss of graft function secondary to fibrillary glomerulonephritis within 7 days of receiving a living-related renal allograft. This case emphasizes the values of combining urinalysis with prompt allograft kidney biopsy in recipients with an elevated serum creatinine posttransplantation. When one encounters rapidly progressing glomerulonephritis or a pulmonary-renal syndrome in the immediate posttransplantation period, fibrillary glomerulonephritis must be considered in the differential diagnosis. Because of a high recurrence rate and no available treatment to modify a potentially malignant course of this disease, we recommend caution when considering these patients for transplantation.
