Posttransplant membranous nephropathy - A case report

Abstract

Primary membranous nephropathy (PMN) is a common cause of adult-onset nephrotic syndrome. Anti-M-type phospholipase A2 receptor (PLA2R) antibodies are pathogenic and correlate with clinical outcomes. The role of anti-PLA2R in recurrent PMN is unclear. In the present manuscript, we report five cases of PMN who underwent kidney transplantation (KT) with varying titers of anti-PLA2R pre-kidney transplantation (KT). Two patients with anti-PLA2R in the second and third tertiles had a recurrence of PMN, whereas patients with a negative or anti-PLA2R in the first tertile had no recurrence. The report signals a heightened risk of PMN recurrence in patients with elevated anti-PLA2R antibody titer at KT.
