De novo minimal change disease

Abstract

Beyond the acute posttransplantation period, glomerular causes of proteinuria in the renal allograft include recurrent glomerulopathy, transplant-associated entities, and de novo disease. We present a case of de novo minimal change disease with reversible acute renal failure occurring 2.5 years posttransplantation in a 56-year-old man. The cause of end-stage renal disease in the native kidney was membranous glomerulopathy. De novo minimal change disease in the renal allograft is an extremely rare entity requiring stringent clinical-pathological criteria for diagnosis. Many of the cases previously reported as de novo minimal change disease fail to meet these criteria. We review the eight reported cases that appear to fulfill a strict definition of minimal change disease in the context of the current report.
