Recurrent Proliferative Glomerulonephritis With Monoclonal Immunoglobulin Deposits in Kidney Allografts Treated With Anti-CD20 Antibodies

Background. Proliferative glomerulonephritis with monoclonal immunoglobulin deposits (PGNMID) is a distinct form of glomerulonephritis that often recurs after kidney transplantation causing severe graft injury and often failure. Methods. We describe post transplant outcomes and response to therapy in 20 recipients with PGNMID. Evidence of PGNMID recurrence or lack thereof was determined by protocol and clinical biopsies.
