Membranous Nephropathy-associated Serological Antibody Predict the Prognosis of Idiopathic Membranous Nephropathy

Brief description of study

Idiopathic membranous nephropathy (IMN) remains a common cause of the nephrotic syndrome in adults and one of the leading known causes of end-stage renal disease. Identification of circulating autoantigens provide potential biomarkers for diagnosis and therapy of idiopathic membranous nephropathy. M-type phospholipase A2 receptor (PLA2R) and Thrombospondin type-I domain-containing 7A (THSD7A) were identified as the target antigen in membranous nephropathy with high specificity and the concentration of serum anti-PLA2R antibody and anti-TSHD7A antibody were helpful for predicting disease activity. In our prospective cohort study, hospitalized patients diagnosed as IMN are prospectively studied. Circulating anti-PLA2R antibody and anti-THSD7A antibodies were recently screened by using enzyme-linked sorbent assay(ELISA). This study aims to analyse the difference of clinicopathological characteristics for different concentrations of serum anti PLA2R antibody and anti TSHD7A antibody, and analyze the association between baseline concentrations of serum antibody and disease activity. This study also explored the prediction effects of serum antibody concentrations with different types of therapeutic regimen in IMN and compare the curative effects of different types of therapeutic regimen in different serum antibody concentrations.
