Clinical Trial Summary

The goal of this observational study is to explore the factors that can predict the prognosis difference in patients with idiopathic membranous nephropathy (IMN) under the treatment of glucocorticoid + cytoxan. The main questions it aims to answer are:

• to explore the factors that can predict the prognosis difference in patients with IMN under the treatment of glucocorticoid + cytoxan

• to establish a clinical prediction model and verify it to provide a reference for the early Participants will receive standard glucocorticoid + cytoxan treatment and will then be divided into remission and non remission groups based on the treatment effect after the standard treatment cycle. Blood, urine, and fecal samples were collected from patients to explore possible factors influencing treatment efficacy.

Researchers will compare [remission group and non-remission group] to see if the gut microbiota and its metabolites are factors that influence the efficacy of treatment.

Intervention

Drug:
• glucocorticoid + cytoxan
The initial full dose of prednisone was 1mg/kg/d (the maximum dose was 60mg/d) for 6-8 weeks, and then slowly decreased by 10% of the original dose every 1-2 weeks, and the later small dose was maintained at 0.4-0.5mg/kg/d; Cyclophosphamide 200mg/time, intravenous drip or oral every other day, up to the cumulative dose of 6-8g.

Primary	Remission	None-Remission of the State of MN: 1) 24-hour urin protein (24-h UP)>3.5 g, or 24-h UP<50% lower than the baseline, or serum creatinine increased by 50% compared with the baseline; 2) Renal function progress: Compared with the initial examination, estimated glomerular filtration rate (eGFR) progress is greater than or equal to 30%; 3) End stage renal disease: eGFR<15ml/min, or renal replacement therapy.; Partial Remission of the State of MN: 24-h UP is 0.5-3.5 g, and 24-h UP is more than 50% lower than the baseline, serum creatinine is normal, and plasma albumin is = 30 g.; Complete Remission of the State of MN: 24-h UP<0.5g, serum creatinine normal, plasma albumin = 35g.	6 months
