Abstract

We report a young woman presented with nephrotic syndrome and normotension during every pregnancy and achieved complete remissions after the deliveries. We thus inferred that her nephrotic syndrome was closely associated with pregnancy. Kidney biopsies were perfromed and showed different histologic patterns: the first biopsy showed a pattern of endocapillary proliferative glomerulonephritis; the second biopsy revealed proliferative glomerulonephritis with monoclonal immunoglobulin deposits (PGNMID) with features of membranous nephropathy. With regard to presentation during the second trimester of pregnancy, achieving complete remission after delivery, and no relapse during the follow-up period, pregnancy associated PGNMID is suggested. To our best knowledge, this is the first reported case of PGNMID associated with pregnancy.
