ABSTRACT
Objective:
To examine the expression ofphospholipase A2 receptor (PLA2R) in renal tissues and the level of anti-PLA2R antibody in serum in patients with idiopathic membranous nephropathy (IMN) and secondary membranous nephropathy (SMN),and to evaluate their diagnostic value in IMN.Methods:
A total of 73 patients,who were diagnosed between May,2014 and February,2015 in the Department of Nephrology of the Second Xiangya Hospital,Central South University,were divided into three groupsan IMN group (n=48),an SMN group (n=17) and a minimal change disease group (n=8) according to the renal biopsy.PLA2R expression in renal tissues and the level of antiPLA2R antibody in serum were detected by indirect immunofluorescence technique.Results:
The positive rate and fluorescence intensity for PLA2R in the renal tissues in the IMN group were higher than those in the SMN group (91.7% in the IMN group vs 29.4% in the SMN group,P<0.05),while the positive rate and serum level for anti-PLA2R antibody in the IMN group were higher than those in the SMN group (85.4% in the IMN group vs 29.4% in the SMN group,P<0.05);the expression of PLA2R in renal tissues and the serum level for anti-PLA2R antibody were not detected in the minimal change disease group,The serum level of anti-PLA2R antibody was positively correlated with 24 h urine protein (r=0.432,P<0.01) and negatively correlated with serum albumin (r=-0.307,P<0.05).Conclusion:
The expression of PLA2R in renal tissues and the serum level of anti-PLA2R antibody might be potential markers for diagnosis oflMN.
