Objective: To assess the correlation between Serum phospholipase A2 receptor antibody and clinicopathological features in patients with membranous nephropathy. Method: The patients being hospitalized for renal biopsy were selected in this study from January 2016 to January 2018. And normal controls were randomly selected; all the patients were divided into idiopathic membranous nephropathy and non-idiopathic membranous nephropathy groups; patients with idiopathic membranous nephropathy were divided into three groups, namely stage I, stage II and stage III; using software for statistical analysis. Results: A total of 357 patients were enrolled, including 155 patients with idiopathic membranous nephropathy, 183 patients with non-idiopathic membranous nephropathy, and 19 cases for normal controls. The average age of the idiopathic membranous nephropathy (IMN) group is higher than that of the membranous nephropathy group (P = 0.01). Different pathological stages of idiopathic membranous nephropathy general clinical characteristics analysis results showed that the age, cys c, serum creatinine (Scr) in stage III membranous nephropathy group were higher than those of the stage I and II membranous nephropathy (P values were 0.003, 0.000 and 0.000 respectively); titers of serum phospholipase A2 receptors antibody with stage II and III membranous nephropathy higher than the stage I membranous nephropathy group (P = 0.006); serum albumin (Alb) levels correlated inversely with serum anti-PLA2R antibody titers (rs = –0.234, P = 0.003), serum antiphospholipase A2 receptor (PLA2R) antibody titer level in patients with idiopathic membranous nephropathy was significantly higher than that in patients with non-membranous nephropathy (P < 0.001). Conclusion: Baseline titer of serum anti-PLA2R antibody is negatively correlated with Alb in the IMN patients，and serum anti-PLA2R antibody level in patients with stage I IMN was significantly lower than stage II and III IMN patients.

Phospholipase A2 Receptor

Background: Anti-phospholipase A2 receptor antibody (PLA2R-Ab) is useful in diagnosing idiopathic membranous nephropathy (IMN). We investigated the clinical relevance of PLA2R-Ab enzyme-linked immunosorbent assay (ELISA) in patients with IMN. Methods: We measured PLA2R-Ab with an ELISA kit from the serum of 160 patients with IMN (n = 93), secondary MN (n = 14) and other glomerulonephritis (n = 41) as well as healthy controls (n = 12) at the time of renal biopsy and investigated the correlation of titers of PLA2R-Ab with clinical parameters. Results: PLA2R-Ab was positive in 41 of 93 patients (44.1%) with IMN. No samples from the patients with secondary MN and other glomerulonephritis or healthy controls were positive with the ELISA test. The PLA2R-Ab-positive patients showed severe disease activity and a low remission rate. The PLA2R-Ab titer positively correlated with proteinuria and was negatively associated with renal function and serum albumin. The patients with a high titer of PLA2R-Ab had significantly decreased remission rates. The cumulative probabilities of remission was significantly lower in patients with PLA2R-Ab (p = 0.01) and even so in patients with a high titer of PLA2R-Ab (p = 0.04). When we compared the ELISA titers with Western blot (WB) data of 43 patients who had been enrolled in our previous study, 18 and 30 patients were positive on ELISA (41.9%) and WB (69.8%), respectively. WB and ELISA had a concordance rate of 72.1% and were positively correlated (r = 0.590, p < 0.001). Conclusion: The presence, as well as a high titer, of PLA2R-Ab on ELISA was associated with poor prognosis of IMN. Assessment of PLA2R-Ab with ELISA is an easy and reliable tool for the diagnosis and guidance of therapeutic plans.
