Fecal microbiota transplantation for membranous nephropathy.

Membranous nephropathy is a pathological type of nephrotic syndrome. Current treatments including supportive therapy, corticosteroids, immunosuppressive agents are not effective for all patients. New therapies are needed to treat the disease safely and effectively. Gut microbiota may contribute to the pathogenesis of this disease. Fecal microbiota transplantation (FMT) has made achievements in many diseases. Here, we report a case in which FMT is used to treat a patient with membranous nephropathy and chronic diarrhea, whose symptoms ameliorated and renal function improved.
