Brief Summary

Multi-center, prospective, randomized, controlled study to verify the efficacy of prednisone alone and combination therapy with methylprednisolone and cyclophosphamide in the treatment of stage I membranous nephropathy.

Detailed Description

Idiopathic membranous nephropathy (IMN) is one of the most common cause of adult nephrotic syndrome. Prednisolone and methylprednisolone are essential drugs for IMN. However, there are no recommendations for the treatment of IMN in China. KDIGO guidelines recommend combination therapy with methylprednisolone and cyclophosphamide as first-line therapy of IMN, but there is a large side effect of cyclophosphamide.There were retrospective study showed that the use of glucocorticoid hormones (including prednisone and methylprednisolone) alone may be effective in patients with membranous nephropathy in Asia, but there is no high quality evidence of evidence-based medicine.The study is a randomized prospective controlled multi-centered trial,to compare the efficacy of prednisone alone and combination therapy with methylprednisolone and cyclophosphamide in the treatment of membranous nephropathy in stage I.
