Fecal Microbiota Transplantation for Refractory IgA Nephropathy

IgA nephropathy (IgAN) is one of the most common glomerular diseases worldwide. Current treatments for IgAN are limited by their relatively insufficient efficacy and severe adverse events. Previous studies suggested that the disorder of intestinal flora may play an important role in the pathogenesis and prognosis of IgAN. Fecal microbiota transplantation (FMT) have been proved to be effective on rebuilding the intestinal microecological balance. However, there is no evidence for the safety and efficacy of FMT in IgAN. Therefore, investigators perform a prospective cohort study to evaluate the safety and efficacy of FMT in IgAN patients who did not response to the conventional treatment and did not want to aggravate immunosuppressive treatments or IgAN patients who did not response to immunosuppressive treatments.
