  • Title: Nephrotic range proteinuria with "minimal change glomerulopathy" in human renal allografts: report of four cases.

    Journal: Am J Kidney Dis; 1988 Jul; 12(1):51-61. PubMed ID: 3291610.
    Abstract:
    Four patients who received renal allografts developed nephrotic range proteinuria 2 to 16 months after renal transplantation. Twenty-four-hour urine protein excretion at the time of renal allograft biopsy ranged from 5.9 to 17.0 g/24 hours. The serum creatinine at the time of renal allograft biopsy ranged from 2.0 to 3.9 mg/dl (180 to 350 mumol/L). Biopsies of the allografts demonstrated minimal glomerular abnormalities by light microscopy, immunomicroscopy, and electron microscopy. Two biopsies exhibited severe interstitial fibrosis. These four cases illustrate the unusual finding of "minimal change glomerulopathy" in renal allograft recipients exhibiting nephrotic range proteinuria. All four patients progressed to dialysis 4, 36, 46, and 53 months after transplantation. Transplant nephrectomy was performed in three patients. One showed acute cortical necrosis. Two showed glomerular, vascular, and tubular-interstitial features of chronic rejection.
