Abstract:Objective To evaluate application value of serum anti-phospholipase A2 receptor antibody in the diagnosis of membranous nephropathy. Methods Fifty patients with membranous nephropathy treated with nephrology in Department of Nephrology, the Second People′s Hospital of Yunnan Province ("our hospital" for short) from July 2014 to August 2016 were selected as observation group. Fifty healthy subjects of our hospital Physical Examination Department were selected as control group. Serum anti-phospholipase A2 receptor antibody and a variety of biochemical immune indicators of the results between two groups were compared, the relationship between indicators were analyzed. Results The anti-phospholipase A2 antibody titer in observation group was higher than that in control group, TP and IgG in observation group were lower than those in control group, the differences were statistically significant (P < 0.05). There was no significant difference in IgM, IgA, C3 and C4 between two groups (P > 0.05). The diagnostic sensitivity of anti-phospholipase A2 antibody to membranous nephropathy was 58.00%, specificity was 98.00%. There was a positive correlation between anti-phospholipase A2 antibody and TP, IgG and IgA (r = -3.954, -0.483, -0.286, P < 0.05), and positively correlated with C4 (r = 0.256, P < 0.05), and IgM and C3 did not show correlation (P > 0.05). Conclusion The technique of detecting anti-phospholipase A2 antibody by ELISA is maturing. The diagnosis of membranous nephropathy by anti-phospholipase A2 antibody detection is a good research direction, and ELISA can be used for quantitative detection of anti-phospholipase A2 antibody, and the change of condition for membranous nephropathy monitoring and treatment of the effectiveness of the assessment, but also has the role of auxiliary judgment.
