Evaluation of efficacy of rituximab for membranous nephropathy: A systematic review and meta-analysis of 11 studies.

Introduction: The use of traditional immunosuppressive medicines for the treatment of membranous nephropathy is being challenged, owing to its limited efficacy and tolerability. Research on M-type phospholipase A2 receptor antibodies has provided a new way for evaluating the efficiency and prognosis of treatment of membranous nephropathy. However, the relationship between rituximab, a monoclonal antibody against CD20, and antiphospholipase A2 receptor antibodies and the drug regimen of rituximab for membranous nephropathy is uncertain.
