Concomitance of IgA nephropathy and diabetic nephropathy in a kidney allograft: Case report and review of the literature

摘要

Whereas diabetic nephropathy is the most common cause of end-stage renal disease (ESRD), IgA nephropathy is the most common glomerulonephritis in the world. We report a case of a kidney transplant recipient whose native renal disease was presumptive diabetic nephropathy. Five years after transplantation, the patient developed proteinuria, hematuria, and allograft dysfunction. Transplant biopsy revealed IgA nephropathy superimposed on diabetic nephropathy.
