The aim of this prospective study was to determine the prevalence of anti\u2010PLA2R in iMN in an Australian cohort.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Serum anti\u2010PLA2R was measured using two techniques, an enzyme\u2010linked immunosorbent assay (ELISA) and a cell\u2010based indirect immunofluorescence test. Kidney biopsies were also examined for the presence of PLA2R using a polyclonal antibody. A group of 21 patients with iMN were compared with a group of 19 patients with secondary MN and other glomerular diseases.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Seventeen of 21 patients with iMN were positive for anti\u2010PLA2R on both ELISA and indirect immunofluorescence test, and 14 of these patients also had positive staining for PLA2R in the biopsy (tissue was unavailable in two patients). Three patients with iMN had positive staining in the biopsy only, and one patient was negative in both the serum and the biopsy. None of the patients with secondary MN or other glomerular diseases had anti\u2010PLA2R antibodies or PLA2R in the biopsy. There was wide inter\u2010individual variation in titre on ELISA, but serial levels within an individual patient enabled monitoring of disease, and a fall in titre correlated with clinical remission.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>This is the first Australian series to examine the incidence of anti\u2010PLA2R in iMN. It is also unique in examining sera by two separate techniques in conjunction with tissue localization of PLA2R. We have shown 100% specificity of both serum anti\u2010PLA2R and glomerular PLA2R in iMN, with a sensitivity of 81.0%. When serum testing is combined with tissue localization of PLA2R, the sensitivity increases to 95.2%.<\/jats:p><\/jats:sec>","DOI":"10.1111\/nep.12624","type":"journal-article","created":{"date-parts":[[2015,9,15]],"date-time":"2015-09-15T11:45:12Z","timestamp":1442317512000},"page":"397-403","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":18,"title":["PLA2R and membranous nephropathy: A 3\u2009year prospective Australian study"],"prefix":"10.1111","volume":"21","author":[{"given":"Prue A","family":"Hill","sequence":"first","affiliation":[{"name":"Department of Anatomical Pathology St Vincent's Hospital Melbourne  Melbourne Victoria Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jennifer L","family":"McRae","sequence":"additional","affiliation":[{"name":"Immunology Research Centre St Vincent's Hospital Melbourne  Melbourne Victoria Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Karen M","family":"Dwyer","sequence":"additional","affiliation":[{"name":"Immunology Research Centre St Vincent's Hospital Melbourne  Melbourne Victoria Australia"},{"name":"Department of Nephrology St Vincent's Hospital Melbourne  Melbourne Victoria Australia"},{"name":"Department of Medicine University of Melbourne  Parkville Victoria Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2016,4,22]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMoa0810457"},{"key":"e_1_2_6_3_1","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMoa1009742"},{"key":"e_1_2_6_4_1","first-page":"1","article-title":"The diagnostic accuracy of PLA2R\u2010AB in the diagnosis of idiopathic membranous nephropathy: a meta\u2010analysis","volume":"9","author":"Du Y","year":"2014","journal-title":"PLoS One"},{"key":"e_1_2_6_5_1","doi-asserted-by":"publisher","DOI":"10.1007\/s40620-014-0042-7"},{"key":"e_1_2_6_6_1","doi-asserted-by":"publisher","DOI":"10.1038\/srep08803"},{"key":"e_1_2_6_7_1","doi-asserted-by":"publisher","DOI":"10.1038\/ki.2012.209"},{"key":"e_1_2_6_8_1","doi-asserted-by":"publisher","DOI":"10.1007\/s10157-014-1054-2"},{"key":"e_1_2_6_9_1","article-title":"Clinicopathological characteristics of M\u2010type phospholipase A2 receptor (PLA2R)\u2010related membranous nephropathy in Japanese","author":"Hayashi N","year":"2014","journal-title":"Clin.
