Study Details

Study Description

Brief 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 tacrolimus. 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 tacrolimus

  • to establish a clinical prediction model and verify it to provide a reference for the early Participants will receive standard the treatment of tacrolimus 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.

Arms and Interventions

Arm Intervention/Treatment
Remission

Drug: Tacrolimus
0.05-0.10mg/kg/d, twice orally, with an interval of 12h. The drug valley concentration is 5-10ng/ml, which will be gradually reduced to a low dose after it is effective.

Non-remission

Drug: Tacrolimus
0.05-0.10mg/kg/d, twice orally, with an interval of 12h. The drug valley concentration is 5-10ng/ml, which will be gradually reduced to a low dose after it is effective.

Outcome Measures

Primary Outcome Measures

  1. Remission [6 months]

    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.
