RESUMO

Hypoalbuminemia in end-stage renal disease is a marker of high morbidity and mortality. In some patients, the cause of low serum albumin levels is easily identified and therefore treatable, but in many patients, the cause is not clear. We studied the effect of changing the dialysis membrane from a bioincompatible to a biocompatible membrane on serum albumin level. Stable hemodialysis patients dialyzed with cuprammonium membranes who had serum albumin levels less than 3.5 g/dL were switched to the more biocompatible membrane, polysulfone. Serum albumin levels increased from 3.22 +/- 0.037 to 3.35 +/- 0.038 g/dL (mean +/- SE; P < 0.002). The increase was seen in patients both with and without diabetes. Thus, dialyzer membrane may affect serum albumin levels and should be considered in the differential diagnosis of hypoalbuminemia in patients undergoing hemodialysis with bioincompatible membranes. Membrane choice may have an important effect on the outcome of morbidity and mortality of hemodialysis patients.

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.
