ABSTRACT
Objective To explore the relationship of phospholipase A2 receptor (PLA2R) expression in renal tissue with clinical characteristics,prognosis of idiopathic membranous nephropathy (IMN) patients.Methods 134 patients diagnosed as nephropathy proven by biopsy was selected as subjects of this research,including 98 patients with IMN patients,10 patients with secondary membranous nephropathy and 26 patients with other renal glomerular diseases.The expression of PLA2R antigen in renal tissue was detected by immuno-fluorescence chemistry staining.Results The positive rate of renal PLA2R expression in IMN patients was higher than that in SMN patients (91.84% vs 40.00%,P< 0.01),whereas there is no expression in other glomerular diseases.The PLA2R negative group were mainly stage Ⅰ membranous nephropathy,and positive group was mainly in stage Ⅱ.The distribution of pathological stage between the two groups was statistically significant (P <0.01).Compared with the positive group,the negative group was manifested with higher eGFR[(115.91± 23.32) ml· min-1 · (1.73 m2)-1 vs (94.06±27.38) ml· min-1 · (1.73 m2)-1,P=0.031],associated with the higher 12-month complete remission rate (87.50% vs 44.07%,P=0.021).Conclusions The expression of PLA2R antigen in renal tissue plays an important role in the diagnosis,disease evaluation and prognosis of IMN.The negative PLA2R in kidney tissue of IMN may indicate a good clinical prognosis.
