RESUMEN

OBJECTIVE: To detect the expression of renal M-type phospholipase A2 receptor (PLA2R) in patients with idiopathic membranous nephropathy (IMN), and to explore the relationship between renal PLA2R and the curative effect of immunotherapy. METHODS: A total of 56 patients who were diagnosed as IMN from January 2012 to June 2014 in the department of nephrology in First People's Hospital, Shanghai Jiaotong University, were included in this study. The expression of renal PLA2R was detected by immumofluorescence assay. The IMN patients were treated with corticosteroids and cyclophosphamide, and the relationship between renal PLA2R and the curative effect of immunotherapy was observed. RESULTS: The ratio of PLA2R related IMN (renal PLA2R-positive) patients was 71.4%(40/56). The recovery conditions in proteinuria and serum albumin were better in the non-PLA2R related IMN group since 6 months after the treatment (P<0.05). The overall response rate in PLA2R related IMN group was 58.3%, 62.5% and 62.5% after 6, 9, 12 months, respectively. However, the overall response rate in non-PLA2R related IMN group almost reached 100% after treatment for 6 months. Compared with PLA2R related IMN group, the time which patients reached complete remission was significantly shorter in the non-PLA2R related IMN group [(5.4±3.5) vs (10.5±1.6) months, P<0.05]. CONCLUSIONS: Detection of renal PLA2R can be helpful to diagnose IMN. Non-PLA2R related IMN patients usually have a better curative effect of immunotherapy and a shorter time to onset of efficacy.
