Core Tip

Core Tip: This is a case presentation of a patient who developed post-transplant nephrotic syndrome 3 mo after transplantation and was diagnosed with de novo membranous nephropathy (MN). He had received a well-matched living donor kidney. According to the literature, the most common causes of de novo MN include secondary causes and antibody mediated injury, which we ruled out. This patient was treated with increased dosage of tacrolimus and an angiotensin converting enzyme inhibitor, which resulted in a good recovery. We favoured a new concept of pathogenesis of de novo MN, which requires the identification of the causative antigens.
