- Abstract
Although membranous nephropathy ( MN) is a commonly observed cause of post-transplant glomerulonephritis, distinguishing de novo from recurrent MN in kidney allograft is often difficult. Phospholipase A2 receptor ( PLA2R) staining is useful for diagnosing recurrent MN in allografts similarly to idiopathic MN in native kidney. No specific treatment strategy has been established for MN, especially when accompanied with HCV infection in kidney transplant recipients. This report describes a 66-year-old man who was diagnosed as having PLA2R positive membranous nephropathy accompanied with already-known IgA nephropathy and HCV infection 26 years after kidney transplantation conducted between identical twins. PLA2R was detected along capillary loops, implying that this patient is affected by the same pathogenic mechanism as idiopathic MN, not secondary MN associated with other disorders such as HCV infection. The patient successfully achieved clinical remission after steroid therapy.
