Idiopathic Membranous Nephropathy
Conditions
Brief summary
Infection is one of common risk factors for relapsing of idiopathic membranous nephropathy (IMN). However, it is still unclear wheather COVID-19 infection can induce the relapsing of IMN. Herein, in this prospective, multi-center, cohort study, the investigator enrolled the IMN patients with COVID-19 infection. All subjects will be followed for three months with four visits at 1, 2 and 3 months. Then the investigator will compare the rate of replase of IMN in the two groups to evaluate the association of COVID-19 infection and replapse of IMN.
